Dynafit 2011/12 — The New Boots

Post by WildSnow.com blogger | January 17, 2011      
Backcountry Skiing

Boots remain one of the most boring and static segments of backcountry skiing gear design. That’s my take this winter, anyway. What’s yours?

Consider the last few years. What was hot? Mama mia, overlap construction! But wait, wasn’t that around 35 years ago? Oh, and wow, some boots were made in China instead of Italy. And whoops, almost forgot, I can stick alpine soles on my touring boots. Excuse me while I pass out from my footwear climax.

Nonetheless, bright spots of innovation exist in the mainstream boot makers (and of course small shops are in the mix as well). Scarpa has stellar performance in their Maestrale, which is admittedly a synergy of incremental improvements to a fairly conventional boot, but end result is the real deal. Garmont is doing a nice job of trying the minimalist approach with their Masterlite. Less is more and all that. Black Diamond is giving freeriders the beef they desire.

But the clear winner in the innovations department has to be handed to Dynafit. They’re still buckle boots. They’re still made in Italy. But with features such as one-motion closure, low volume lasts, use of nylon plastics, carbon fiber and other knicknacks, I’ll admit that despite my yawning cynicism, this Dynafit shoe stuff has been pretty interesting for the last couple of years. The coming season is no exception.

Dynafit Red Machine, Franz Klammer's secret weapon during Olympic downhill race of 1976.

Overlap cuff. Four buckles. Polyurethane. The latest in performance ski boots? Nope, this is the Dynafit Red Machine, Franz Klammer's secret weapon for his legendary win of the Olympic downhill ski race of 1976. Many of today's boot designers were not even alive when this boot was state of the art -- and it still could easily ski as well and be just as comfortable as most of the boots on the market today. My point? Boot innovation is not exactly growing like a weed in a rain forest.

Yes, while the Red Machine of 1976 looks amazingly familiar, incremental evolution is indeed happening in randonnee AT ski boots. (And to the credit of boot designers, I’ll admit that making the better AT boot is no simple task.) Today, check out what Dynafit is doing to that end.

The full line of Dynafit boots for 2011/2012 is impressive, although most are really fairly conventional. Click image to enlarge.

After having seen all of Dynafit’s new product in one place (European product launch press event, Austria), I’m here to say the boot lineup is their most impressive product category this year for changes, design, and overall improvement (that is unless the Dynafit binding Power Towers really work, and in that case it’s a tie).

Indeed, with the addition of their Evo race boot (see below) as well as improvements such as a lighter weight Titan 4-buckle, Dynafit is raging. Even so, I’m not sure I’d call this (and what other companies are doing) a macro evolutionary event of cataclysmic import (that red Dynafit still looks awfully familiar), but it’s certainly a bit more interesting than things were in the boot world a few years ago.

Green machine backcountry skiing boot.

This year's Green Machine ZZero boot from Dynafit has what's essentially a carbon cuff, and brings back the original carbon buckle shield over the instep (a brilliant feature that prevented 'crushing' during tight buckling). This offering is lighter and stiffer than the previous 4-buckle green boot. Super. Click image to enlarge.

Dynafit ZZero 2011-2012

Dynafit ZZero 2011-2012

First up, as in photo above, Dynafit has split the ever popular four-buckle “Green Machine” ZZero 4 into two boots. What was formerly the green Zzero is now white with red highlights but functionally the same as last year (photo to right). Now they’re doing a green ZZero with what is essentially a carbon fiber cuff. This shoe appears to be a truly sweet item. Still easy to customize, but yielding even stiffer performance at 1,580 grams per boot (size 27.5, thermo liner). That’s at least 10 grams lighter than the stock Zzero last year. Not a quantum change, but noticeable especially considering the boot is obviously a bit stiffer due to the added carbon fiber.

Green Machine carbon cuff has Pebax flaps under buckles, which is probably a better closure system than pure carbon. Click image to enlarge.

It’s been a hoot watching AT boot makers play around with the “freeride” market. I’ll just say that at this recent press event, I’m not sure there was one skier who I’d call a “freerider.” Even so, the concept of freeride tour skiing, meaning you use gear that can perform on the down in a more conventional sense, (rather than, for example, making survival turns on 65 mm waist rando race skis), is a solid idea. Thus, Dynafit’s freeride boots continue to be a terrific area where they’re combining almost alpine-like performance with touring walk modes and reasonable weight.

In the freeride category, last year’s Dynafit offerings were headlined by the ZZeus and Titan. This year they’ve lightened the Titan a bit with some carbon fiber and a few other tweaks — they’re calling this iteration the Titan Ultralight. At a claimed 1,750 grams (size 27.5), if this boot skis as stiff as last year’s Titan, then it is indeed impressive and could be THE go to shoe for those of you who want a beef boot that still tours.

Titan Ultralight backcountry skiing and ski mountaineering boot.

Know that last year’s Titan model also continues, as does the ZZeus (the latter in a changed color scheme of grey with yellow hardware, while Titan continues with white and red color scheme.) For the ladies, ZZeus is available in the Gaia model, in off-white and grey with the women’s shape spoiler and liner cuff.

Last season’s big Dynafit boot hype was of course their TLT 5 variations. TLT 5 provided super light weight along with nearly one-motion mode changes and a metatarsal hinge/bend. I’m still planning giving these guys a go, but am finding the concept a bit of a yawner since the company is obviously going the direction of no metatarsal bend, while racing towards weight targets that can only be called emaciated — but in a good way.

The start of the trend is the new Dynafit Dy.N.A. Evo race boot. Carbon cuff with Pebax front straps, nylon plastic lower shoe that’s obviously engineered to the ultimate minimum possible thicknesses that injection molding allows, one-motion mode changes but of course, and weight significantly less than 1,000 grams per boot (size 27 range).

Dynafit Evo backcountry skiing ski mountaineering boot, racing.

Dynafit Evo is the evolution of Dynafit backcountry skiing race boots. When I picked these up, the lack of weight blew me away. I want some for touring. Click image to enlarge.

I spent about three hours in the lab where they’re developing the Evo, and I can honestly say the technology is impressive. Still, it’s interesting to note that injection molding thin plastic ski boot lowers out of harder plastic to save weight is not a new idea. Scott did it just after the pyramids were constructed, and Dynafit’s own boot guru, Mario Sartori, was working on the same concept with Garmont back in the 1970s. He even has a catalog from that era he enjoys sharing and chuckling over. Indeed, Mario has about 30 years experience with this type of boot construction — the Evo is dialed!

What else? Here is the outline:


TLT 5 has a small amount of metatarsal bend, almost imaginary if you're a smaller person, noticeable if you're heavy enough to bend it. Removing the tongues for the uphill is a debatable feature.

– TLT 5 series is comprised of three models (or four if you count a TLT 5 Mountain with a different liner): TLT 5 Performance (carbon cuff), TLT 5 Mountain (nearly same boot, around 200 grams heavier with thermo liner), TLT 5 Mountain Women (I like mountain women, and I hope they like their boot. Essentially a TLT 5 with off white body and purple accents, enlarged spoiler area for calf shape some women have that’s different from men.)

TLT 5 womens model backcountry skiing boot.

TLT 5 womens model, off-white with purple highlights.

ZZero4 PX — The Zzero-like boot with a PU plastic stringer instead of carbon fiber, now yellow for men, white and grey for women. Really quite a nice boot with a better price point than full-on ZZero with carbon stringers.

Zzero 4 U — Urethane versions of above ZZeros, men’s is red, women’s is off white and black, with some little green leaves so you can presumably look down and know you’re covered.

ZZero PX –Budget three-buckle boot models, male and female, without stringers on cuff. A totally viable option though it’s weird they have two buckles on the tongue and only one on the cuff. Seems to me it should be the other way around.

Well, that’s it, let the comments commence and we’ll flesh out the details as much as is humanly possible.

Bonus shot. Skiers have been devising creative ways to carry the TLT 5 removable tongue. While amusing, we're not sure this method is advisable in high winds.

    nice..what about zzeus?
    will it be any changes on those boots?

  2. Lou January 17th, 2011 5:08 am

    Pete, they just look different, same boot as far as I can tell. The lower shoe is transparent off-white, upper is dark grey or black, yellow buckles. They look nice, very freeride-ish. Second from left in the photo above that shows total line, as well as second from left in the photo in my teaser post:


  3. aviator January 17th, 2011 6:25 am

    I know you said it’s probably a proto and they haven’t finalized the weight but…
    holding the evo in your hand, perhaps even comparing it to an older dy.n.a or tlt5p at the same time? would you say it’s 750g-ish or 850g-ish? that must be the ballpark we’re talking?

  4. Lou January 17th, 2011 6:35 am

    I’d say the 850-ish range.

  5. Harry January 17th, 2011 7:39 am

    I am already trying to figure out how to get my TLT 5 Performance tongue on the Evo lower shell.

    It will be interesting to see how the weight savings on the Titan Superlite compare with the weight savings I have done on my current Titan. Dy N. A. buckles are nice and lite.

  6. Mike Bromberg January 17th, 2011 10:10 am

    I’m with ya Lou, definitely a bit of a yawner overall. It looks like the new green machine has a better walk mechanism, I was hoping for tlt5 type technology in a stiffer, beefier boot..

  7. Lou January 17th, 2011 10:20 am

    Mike, this stuff is race driven, so what we have to do is wait till the Evo gets full swing production and economies of scale make it possible to build on that platform. Lot’s of potential, but I’m not holding my breath for how fast it’ll pan out. Meanwhile, if a person could afford the price of the Evo they could pretty easily build it into a touring boot, it might even work well in its stock configuration, for all I know.

  8. Frame January 17th, 2011 10:38 am

    Hey you guys, don’t tire on the boots! Some of us desk jockeys / week skiing warriors (or is that weak) have lunch hours to fill with reviews of boots, while contemplating their blisters (from touring in alpine boots), that they are looking to turn into a solid reason for buying a lightish boot that tours with swappable AT/Alpine soles (so there is less to carry on a road trip across 3 countries to get the aforementioned blisters or take on a plane) and devour this stuff. As it is the other half has made an outlandish suggestion that I only take one pair of skis next time (they take up room in the car or carrying a bag with her ski’s and 2 pairs on mine on planes/trains near killed my shoulder…. funnily she never offered to leave her ski’s behind). 😛

    That’s a lot of words and bollocks for 2 sentences!

  9. Andy January 17th, 2011 10:51 am

    Perhaps I’m missing something, but is the carbon on the cuff of the new green machine only on the back and sides, or is most of the entire cuff carbon? Wondering how much stiffer in forward flex it would be if the carbon doesn’t go around the shin.

  10. Lou January 17th, 2011 11:09 am

    Andy, the trend seems to be to make the cuff part carbon and part Pebax, so it’s easier to get in and out of and a bit more forgiving. The forward flex is a much a function of the touring lock and carbon backbone, so if the boot is well designed it shouldn’t really need the carbon going around the front. In the end, you’ve got to ski ’em and find out for yourself of course…

  11. lawtalkinggirl January 17th, 2011 11:47 am

    Please show us mountain women the TLT 5 for women! We read your blog too! 8)

  12. wick January 17th, 2011 12:22 pm

    I believe the TLT 5 Performance/F1 Carbon/Evo style boots are the way of the future….I can drive my car with the boot on (Upper cuff articulation rocks for touring and driving) ….and when locked into DH mode, with a one buckle throw, carbon upper cuff and destroy vertical pow…why would you ever go 4 buckle with a Frankenstein looking stride?? Training wheels??

  13. Eurob January 17th, 2011 12:33 pm


    from your ZZero 4C review i took away that the boot was stiff enough. Are you really lusting for more rigidity?

  14. Lee Lau January 17th, 2011 12:51 pm

    eurob. The ZZero was fairly rigid laterally but a bit soft in fore-aft. I suspect (emphasis here till a test pair arrives) that the boot will be a bit stiffer fore-aft. This test won’t happen any time soon though fyi

  15. Omr January 17th, 2011 1:05 pm

    Andrew Mc. . made an astute observation when he said tele has pretty well evolved itself out if existence by going bigger, beefier, and heavier. AT is slowly doing the same by going lighter, squirrel-ier and softer. If the trend continues, in a few years i can take my Merrill Super Doubles and 3-pins out of moth-balls, and look cool doing so. My ski partners, who went AT early and lobbed plenty of crap on all us tele die-hards, and who are now going superlight AT, are now again skiing like they are on tele gear: arms wind-milling, wide-stance and falling every third turn. If the snow is not perfect they are whining and making excuses like a true tele-dude. For downhill performance, boots have almost come full circle.

  16. Tony January 17th, 2011 1:29 pm

    OMR, If your buddies are windmilling & falling & flailing on a set of Stokes or Manaslus paired with a TLT5… I’ll give you a hint : it isn’t the gear.

    If they’re doing it on full race gear, understandable – but that doesn’t signal de-evolution of AT, just stupid decisions on the part of your buddies.

  17. skian January 17th, 2011 1:39 pm

    Zzeus has new PU formulation and color way. Slight mode to liner. Bit wider in toe box area.

  18. AndyC January 17th, 2011 1:41 pm

    I’ve found my TLT5 mountains to be a perfect match to my 187 Manaslus, at least in powder. They actually seem stiffer than my Zzero4 PU TFs (and the same height at the cuff) and taller and stiffer than my Zzero3 Pbax MFs. I didn’t thermofit the liners and after 3 days of powder skiing, the fit is pretty good. I don’t use the downhill booster tongue at all because it makes the boot too stiff fore and aft for my taste in powder skiing. I had to remount my bindings for my size 29s and while the forward lean is 15 degrees it seems a slight excessive, maybe a little more ramp angle or maybe just need the upper liner broken in some more. I love the 2 buckles and power strap–very quick transitions and the fore and aft rotation of the cuff in walk mode is all it has been claimed to be. The boot was comfortably cool with my lightest weight socks in powder that fell at 7 F and air temps 13-15F.

  19. Jason January 17th, 2011 2:25 pm

    I think we, the backcountry ski consumers, are to blame for the lack of true excitement in ski boot evolution. The true revolution is carbon, but manufacturers are reluctant to put more carbon in their boots because of the expense. Look at the people complaining about the expense of TLT5s. Until we are willing to pay as much for gear as other sports (i.e. road biking, mountain biking, golfing, snowmobiling, flyfishing, jetskiing, etc.), we will see these slow evolutions.

    The technology exists to have ski boots that perform as well as the stiffest Alpine race boot that tour as well as any boot at less than 750 grams. But people would complain about the $1500+ price tag.

  20. Lou January 17th, 2011 2:56 pm

    Jason, that is a VERY good point. I think what happened with bicycles is a psychological barrier was passed some years ago, when people realized it was worth it to pay more for their bicycle than their car. We have not gotten there with ski boots yet, perhaps because they’re small and not mechanical like a bicycle.

  21. Lou January 17th, 2011 3:00 pm

    Law girl, thanks for laying down the law. Photo of female TLT5 is published above.

  22. Christian January 17th, 2011 3:24 pm

    People are spending more and more on gear, and it is getting better and better. I am currently skiing the tlt5p and mustagh ata sl. This is the best rando gear I have ever had – and the most expensive. “Montagne” gave the 999 euro super light alpcontrol ski top scores in all categories…

  23. Jonathan Shefftz January 17th, 2011 3:33 pm

    Lack of excitement in ski boots? Only compared to last season’s DyNA and this season’s TLT5 Performance. The price premium is painful, but being able to tour uphill with a weight comparable to beefy hiking boots along with nordic-esque lack of stride inhibition then ski down with all the stiffness anyone really needs for backcountry conditions, the only drawback is that future improvements can never be so dramatic. (Well, the other drawback is that the narrow and low-volume last causes fit problems for many folks, but I just consider this the revenge of the slender footed!)
    And at the other end of the spectrum, plenty of offerings for those who are mainly riding lifts but want a boot for the occasional skintrack. Far from evolving itself out of existence, AT (and especially Dynafit) is now offering something for everyone across a huge spectrum (i.e., from all-around performance at race weight to true alpine downhill performance at what was recently considering all-around weight), and rendering tele even more pointless than it already was.
    I am a bit surprised though that the Zzero cf upper seems to wrap around less than the TLT5, and that the Titan cf seems to be limited to just the rear spine. Still though, lighter for the up and stiffer for the down, can’t complain (as long as you can afford it).
    Also, if the DyNA Evo is 850g per boot, then the 27.0/27.5 is only 3 oz less per pair than a 26.0/26.5 after some inadvertent spring/summer bootsole rubber reduction. (I know, apples & orange with the sizes, but still seems relatively minor.)

  24. Lee Lau January 17th, 2011 3:40 pm

    Not to harsh the Dynafit buzz but there’s one boot that stands out as getting better and better (lighter, stiffer, improved tourability) yet at a lower price – the Scarpa Maestrale.

    The old joke was strong, light, cheap. Pick just two. Maestrale is the exception to the rule on that old joke.

    No list prices on the Dynafit boots yet for Noram to my knowledge so it’s difficult to speculate on what would be the direction of pricing.

  25. Federico January 17th, 2011 4:03 pm

    … still not officially revealed but the DyNA Evo in size 27 is pretty much ligher than 850g guys! … climbs really great and ski pretty good.

    I personally think there was pretty much work and evolution done in the last few years, the TLT5 P is a good example! 1kg boot which climbs great and ski on a much higher level of performance than the beefiest touring boots of 5-6 years which weighted nearly the double! .. how do you call it?


  26. aviator January 17th, 2011 4:18 pm


    much less than 850g sounds good!

  27. Lee Lau January 17th, 2011 4:23 pm


    Consumers are very demanding and have conflicting needs. Now you folks at Dynafit have done the inconceivable with such innovative boot designs consumers are demanding the impossible and with such competing and different demands – you know – Your boots are too wide, your boots are too narrow. I like the bright colours, I like the boots to be black. Your boots are too soft, your boots are too stiff.

    But I am sure that Dynafit, and many other boot companies will continue to innovate and come out with more shiny new things for all of us to fondle and drool over. To be fair, the TLT5’s marriage of light weight yet excellent ski performance is going to be tough to top at a reasonable pricepoint.

  28. David January 17th, 2011 4:26 pm

    Not following this lack of evolution in boots line of thought….
    I believe this years TLT5 performance is truly revolutionary.
    Was good enough to pry $$ out of my wallet and absolutely no regrets – I love this boot every time I get out on it.

    Its an evolution of race (DyNA) technology and came to mainstream retail remarkably quickly. Think how long it takes auto or cycle racing technology to hit retail channels.

    And its relatively cheap too at about 1.66x the next best thing (Maestrale according to Lou)
    Cycle racing technology for the mainstream consumer costs a heck of a lot more than 3x the “average” stuff.

  29. Mike Bromberg January 17th, 2011 4:50 pm

    No doubt that the DyNA, TLT5 and evo are huge leaps forward. I personally would have hoped to see (was expecting) more of a “freeride” oriented boot with similar tourability as the TLT5… Maybe higher cut or with another buckle? I’m certainly not opposed to more carbon in all these boots even with the higher price tag.

    With that said, I’d love the opportunity to put the TLT5 through the ringer. This season I’ve been on Maestrale’s for touring and Titans for gravity fed. I had hoped to be on Titans/TLT5p’s but I’ve been satisfied with the Maestrale…

    It’s true that Dynafit has boots on both ends of the spectrum, but I suppose the middle of the spectrum (maestrale territory) is still somewhat less inspiring. At the end of the day, what I want is a daily driver that can be efficient both up and down, and be durable enough that I get more than one season out of the shells.

  30. Omr January 17th, 2011 5:08 pm

    Tony and Jason, Yeah, the human element is aways the biggest factor. My friends are on TLT5’s, on various skis, and they USE to be darn good skiers. Bottomline: I’m still ripping on my Radiums while they now face-plant far more than they ever did pre-TLT5’s. Every generation of equipment has good and bad ideas. Hopefully this ‘Chuck Taylor’ stuff will pan out. Terrain is the ultimate test; remember how SX91’s were all the rage for a short time during the ’80’s? In comparison Klammers Dynafits were light-years ahead. (see b of a’s for great skiers being tossed on boots way too-soft). But that’s my whole point: where are we headed? Back the leather, lace-ups?

    And what’s with these Rando racers and their one-time-use skin tracks?

  31. KDog January 17th, 2011 5:46 pm

    As Dynafit’s boot selections grows, so does my brains inability to keep all the names and numbers straight.

    Zzeus/Zzero 3/4/UTF/PU/CF/WTF!/PX/DyNA/EVO/TLT5/P/M/MW/Titan UL 😯

    How about a boot named “Joe”?

    Try doing a Google search on one style of their boots and you will come up with 5 models. How do retailers decide on what to carry? My local shop carries 4 models of boots total (of all brands available). They can’t afford to stock more than that and they are kicking themselves for not carrying the Maestrale this year.

    Variety might be the spice of life, but in a weak economy it makes it hard to try on a specific pair of boots.

  32. Greg Louie January 17th, 2011 5:56 pm

    Omr, your friends used to be good skiers and suddenly became hackers after buying TLT 5’s?

    Something suspicious about that, it’s certainly not my experience. The boot required some “dailing in” like any piece of gear, and the lack of mass doesn’t inspire confidence in certain conditions (ie. breakable crust) but they definitely don’t lack for support.

  33. Josh Marvel January 17th, 2011 8:44 pm

    Any word on the specific changes to the Titan Ultralight? I see the carbon stiffener but I’ve heard that most of the weight savings is actually in the liner.

  34. Mark W January 17th, 2011 10:15 pm

    TLT 5 impressed me with the exception of the velcro strap on the liner tongue. That thing needs to go!

  35. Lou January 18th, 2011 12:03 am

    Kdog, I agree. In my opinion Dynafit could have a much more solid boot brand if they worked a bit on their naming. Same goes for the bindings. I have no idea why they have to prefix with the word “TLT” for example. Couldn’t it just be the “Speed Radical” and the “Radical FT?” Seems like it’s some kind of cultural thing, where the longer the name the more significance it has.

  36. Christian January 18th, 2011 1:10 am

    Mike: Dont you feel that the tlt5p is in the middle? I see no need for anything between them and the titan. The new green machine might be there though…

  37. Federico January 18th, 2011 1:42 am

    HAHAHA, a lot of people loves our names guys… anyway that’s really not something which makes any difference in selling 🙂

    Mark… this little velcro on the liner is made for those guys using race binding heel part (always with a little heel raise) and going with long and fast gliding steps on flat terrain. in this case the velcro prevent the liner tongue to go out from the liner cuff… if you don’t like it it’s made in a way you can easily cut it.
    Try to look the world from a wider angle guys, there are many skiers in the world with different technique and different requirements… 🙂

  38. Kaz January 18th, 2011 8:56 am

    Glad to see the psych for our new boots!

    To preface, I am a bit biased as I work for Dynafit/Salewa, but…I have been skiing the TLT 5 Performance for about a year now (having skied the Zero 4C previously) and truly have not found a need to go back to the Zero 4 C. The Zero 4 C is a great, great boot and arguably, a bit warmer for folks who have a higher volume foot…but from the pure standpoint of touring and ski performance this boot (TLT 5 Series) has been nothing short of stellar.

    I am sure Skian would agree as he skis the same shoe…

    Fede and his design team continue to provide skiers with purpose built products…

    Hope you all enjoy the rest of the 2011/12 Line-Up…some great products in Apparel, Skis, bindings and Packs.

    I just spent 20 minutes on this super well thought out answers and hit delete instead of send???? That’s what happens when I work first instead of ski. I have over 50 days this year on the tlt5. Nothing compares to this boot, It walks ridges better, Climbs couloirs better drives the accelerator pedal better hits the dance floor better and gets you those curious conversations at the coffee shop better than any other boot. But it lacks warmth for those bitter cold days.
    I have had many days this year jumping out of the truck to head out and it’s pitch black and the thermo on the dash says -28 or lower. I need a Titan for those freeride days and for Speed Touring I love the TLT. Long days, multiple peaks and moving fast. Nothing retains insulation but dead air. You lack this in a tlt5 and for most they will never notice this because all the other features just blow you away. The new green machine is also in a class of its own. It is not side by side either or with the tlt or the titan. I will say it again “Light is right but weight is great”, and volume is too. How many bikes in your garage?? DH, MT, Road Racing, Touring, pump track?? Lets stop comparing either or but how many days in each. Dynafit engineers and designers have again hit another home run. Start saving now and bringing coffee and tea to your spouse with the paper your gonna need some love to get this boot. You will have to earn before this turn. It’s not cheap but its not for every Tom, Dick or Harry. I will not
    lie i have been begging for mine for the last three months. I’m frothing at the mouth.

    After using my DyNA almost exclusively last winter, I sold my Zzero4C in the spring in anticipation of the TLT5 cf, and have not been disappointed.
    On both the DyNA and the TLT5, I think the liner velcro works well: the liner is designed to stay with the your leg while skinning, with the shell upper cuff far out of the way.
    I agree that deciding which boots to stock must be a difficult decision for a retailer. But at least the names have improved somewhat over the recent past, when every Dynafit product started off with TLT and then the rest of the product name consisted of the unabbreviated words rearranged in various ways, e.g., TLT Tour Lite All-Terrain Tech Lite ski, etc.

  44. skian January 18th, 2011 1:24 pm

    Frankly i don’t care if they call it the mountain fart if it does the job.

  45. Lou January 18th, 2011 1:28 pm

    You might not care, but about a zillion marketing people actually do. Each person to their own profession 😀

  46. Sam January 18th, 2011 2:46 pm

    I never get tired of watching that Franz Klammer clip!

  47. Brad January 18th, 2011 7:05 pm

    Any idea whether some of the weight savings in the green Titan comes from a lighter liner? (I hope so–that way my “old” Titans, with replacement liners, won’t be *that* much heavier than the new ones.)

  48. Lou January 18th, 2011 11:37 pm

    Brad, yeah, probably. And yes, with boots like that they’re frequently so similar in weight that even adding footbeds can make a “light” boot “heavy.” Basically, that’s what I mean about boot development being boring. I mean, when they call a boot the “Ultralight” and it’s not significantly lighter, how is that exciting?

  49. skian January 18th, 2011 11:50 pm

    I don’t think your looking hard enough.

  50. Federico January 19th, 2011 5:12 am

    The titan ultralight is light! it’s not coming from the liner, that’s just a few grams lighter but from the shell material, pebax instead of PU… the new titan is 1.800gr in size 27,5 … which is more than 200gr less than the old titan.
    With that weight it goes very close to classic ski touring weights, zzero and so on and ski hard like a over 2kg boot!.
    Titan ultralight will be in the market next year the best performing freeride boot with high level of touring abilities and BY FAR the lightest!. That’s it.

  51. scottyb January 19th, 2011 9:41 am

    I wish to say first off I like to read eveyones opinions and thoughts, I am more of a lurker here.

    I am a AT convert after decades of tele both on XCD and HD gear, still do on occasion. Right now I ski mostly Dynafit binders and sometimes my NAXOs but all with my Zzero4cf(green machines). I have been a Scarpa guy for many years. The Zzero is one of the best boots I have ever skied. I ski it in walk mode so a stiffer version would not matter to me, maybe I will come over to lock mode later. That said I just bought, second hand, a set of Titans to use primarily at the ski areas. I would not really want a light weight version of the Titan.

    I usually keep a two boot quiver, back up and all that plus spare liners. It great that the “D” is working up new versions for different folks. Some of it I scratch my head at but different boots for different folks.


  52. J_Castro January 19th, 2011 9:55 am

    Is that next years 7SSL behing the new Zzero’s?

  53. Luke January 19th, 2011 4:24 pm

    So is the new TLT 5 identical to the one out now? Or did it lose the metatarsal flex as well? I can’t really tell from the photos but I’m thinking it’s the same (with flex). Can anyone confirm if it’s identical? I’m probably gonna go get me some of those…

  54. Lou January 19th, 2011 4:30 pm

    Luke, TLT 5 is virtually same as last year. Fede?

  55. Brad January 19th, 2011 7:05 pm

    Lou and Federico,


  56. Ben W January 19th, 2011 7:18 pm

    Is the walk mode on the new green Zzero the same mechanism as the old Zzero’s?

  57. John January 19th, 2011 10:25 pm

    Lou and Federico,
    Topic: Toe piece pull out
    Background: I have witnessed a toe piece pull out by one of the worlds top ski mountaineers no less then a minute after we skied a no fall pitch. Lou has photos of this which I’d like to keep private. This particular case of mounting may be questionable.

    Since Dynafit is redesigning their bindings, I have both a question and suggestion related to binding mounting. It is difficult to calculate screw pull out force when the female material is weaker then the screw. But by simply increasing the diameter of the fastener by 1mm, keeping engaged length and thread pitch the same, the mathmatical pull out force can be increased by 20%.

    I mount with West Systems low viscosity marine epoxy (will penetrate CF and wood) and because it is impervious to water (unlike most over the counter epoxies) it will strenghten the area around the fastener also increasing pull out strength, at least in wood or foam core.

    Will Dynafit consider increasing the fastener diameter?

    On a good note, the unamed skier did finish the trip on my pre-season Stokes. I have Dynafit bindings on all of my skis, and I trust they will not pull out, because I am meticulous about mounting.

  58. Federico January 20th, 2011 1:54 am

    Ben, the new Green Machine has a different mechanism and a different cuff shape, this allow a much wider cuff rotation and better walkabiliy.

  59. Lou January 20th, 2011 7:01 am

    John, I don’t know of many (if any) alpine bindings that have more than 4 screws holding the toe to the ski and they don’t seem to need larger screws or have any particular problem with pull out. That’s using standard binding screws just like Dynafit.

    In my opinion, after years of using Dynafits and mounting hundreds, correct mounting is the key, not using bigger screws. It’ll take quite a bit to change my opinion. I’m just not seeing bindings popping off skis right and left…

  60. Randonnee January 20th, 2011 9:23 am

    I am a 100 kg – weight Dynafit skier who tours 80+ days per years. No problems ever pulling Dynafit toes off of skis, and I am able to stand and intentionally release- with some real effort- from a locked Dynafit toe.

    My Dynafit binding heel pulled from my new FR10 ski when it came out several years ago. I was on the highest heel setting and skinning maximum steepness on a narrow ridge to avoid avalanche hazard, pushing very hard with my bullk, and I pulled the heel off. That ski is foam core. Dynafit replaced the ski and I am still using the same pair occasionally early season as rock skis. But I quit using the high heel setting on that ski.

  61. jmr January 20th, 2011 10:49 am


    Note that they are on TLT 5 and skiing without arms wind-milling, wide-stance and falling every third turn. :mrgreen:

    But Mr. Montaz is a good skiier ( and a CHX Guide).. and to be honest he looks better on slightly beefier gear.

  62. Christian January 20th, 2011 12:54 pm

    Nice video. IMHO I prefered her skiing to his…but both good skiers (more balanced). Well within the limits for the tlt5(at least the tl5p which is the only I have tried). Also recommend gillesleskieur videos: e.g. on k2 darksides – that was a combo I did not expect. (http://www.gillesleskieur.com/)

  63. Justin January 20th, 2011 7:41 pm

    It looks like the light Titan still has the removable soles, is that right? I wonder how many people actually swap out the soles on those. Especially since the goal with that boot is to make it lighter than the original, it seems like a normal (non swappable) AT sole would save even more weight (and make them more modifiable, the sole attachment limits your ability to stretch the toe area of the shell).

  64. Jean-F January 21st, 2011 10:33 am

    Hy there,

    I have a problem with my Dynafit Zzero, third Season, I took them out the first time this season yesterday on my pair of Coombas with Dynafit FT12, normal day, no fall.
    Today I look at the shoes:

    On both Shoes, in front on the right side, there is crack in the green plastik that goes from behind the front metal insert to the Sole…!!! As if the metal moved down and brocken the plastik…

    Seems like these shoes are finished, good for garbage?!?

    Is this Problem known by someone here?

    I will try to go back to the shop and ask for Warranty?

    Thanks for your answers


  65. Lou January 21st, 2011 11:05 am

    That is a known defect that seems to affect a fairly small number of boots from early manufacturing run, but enough to where I’m getting pretty tired of hearing about it. In fact, I’m wondering if a recall is appropriate for ZZero boots of a certain manufacturing vintage (a couple of years ago). Again, I’m getting sick of hearing about this. And Jean, you should be able to get them replaced for no charge.

  66. tony January 21st, 2011 11:33 am

    This isn’t a problem now, but judging from what happened to my Zzeros it will be a problem for me in a season or two

    On my Zzeros, the toe area of the rubbler sole became trashed after two seasons of rock scrabling. The rubber and plastic right under the toe sockets wore out to the point that that I had a couple of mm of the toe socket metal showing when looking at the bottom of the sole. Unlike my old Megarides, the Zzero soles were not replaceable becasue of the configuration of the quick step in toe sockets. After three seasons the wear got to the point where clicking into the toe piece of the binding became harder (Lou fix for this problem is a dab of JB Weld on the toe piece trigger point.).

    I think I remember reading that on my TLT5s, the portion of the sole made out of yellow rubber at the toe and heel were designed to be replacable. Lou, can you confirm this and also find out how we do this? Judging from how fast my Zzeros wore, I will want to do this by the end of the season to avoid wearing into the plastic between the rubber sole and the toe sockets.

  67. Jean-F January 22nd, 2011 4:07 am

    Thank you for your answer Lou,

    will go to the shop today and try to get my Dynafit exchanged.



  68. Federico January 24th, 2011 8:36 am

    Ciao, I know this answer will not sound nice but it’s the truth.
    This little crack on the toe area of the old green machine, only happening in the first production run, is a purely aestetical problem!.
    It’s too long and too complicate to explain why but this lilttle crack is only on the external side, the inserts are hold on the central part of the shel so they will NEVER broke completely.

    Tony, who told you the soles of zzero are not replaceable? of course they are like all footwear/ski boots soles. They are also sold as spare parts and a good shoe maker can easily replace them.
    The problem is that now you walked a lot and wore out all the plastic until the metal inserts the replacment will be very complicate to do.

    The TLT5 are much more durable as they are much thicker on that area compare with the ZZEro. This is one of the good point of making ski boots working only with dynafit bindings… we can do them without respecting the norms for making them compatible with the classic touring bindings which restricts a lot how to build the shell toe shape/thicnkess and consequently the outsole thicnkess…

  69. Lou January 24th, 2011 9:48 am

    Fede, it is well documented that some ZZeros have had the front of the sole actually break due to cracking. Thus, yes, some boots have an aesthetic crack, while others actually break. My understanding is it’s only an early production run that breaks. Nonetheless, I have seen this with my own eyes. It seems pretty rare and only on older first-run boots, so I never panicked in terms of blogging. Also, the word has been out for a long time, But we need to be clear about this. If necessary, I’ve got photos somewhere I can dig up and publish, and I think there is something floating around on TGR or elsewhere.

    Thus, let us be clear that some boots have a crack that is only one to the eye, while others actually break. The question is, how does one tell the difference? What can your dealers do for a customer who has a visual crack? Are they going to tell them with 100% confidence that the boot will not break? If so, wonderful. But that’s what they need to be able to say.

    I have a pair of Green Machines with what are probably the visual cracks. Nonetheless, this caused me to leave them home for my Denali trip and use my Scarpa Spirit 3s instead. I just couldn’t be sure. Again, how can a person be sure it’s only aesthetic, when some have broken?

  70. Lou January 24th, 2011 9:53 am

    Tony, in Dynafit’s defense, it is a known compromise to have thinner sole under the quick-step-in fittings. The problem is that to maintain DIN/ISO standard sole shape, as well as have boot work in tech bindings, what can be done to make rubber thicker is limited. That’s why I still think the old style tech fittings are viable. Look at Garmont boots for example, with the old style tech fittings, and observe how much sole rubber is below the steel fitting and the plastic. Quite different. All this stuff is about compromise. I personally like the Quick Step In fittings and am willing to have my boot toes wear out faster. But if a person does a lot of rock scrambling, they might want to avoid buying boots with thin sole material under the tech fittings. Such thin sole material can be worn out and scoured off in one climb!

    I’d add that Dynafit does provide more sole material under the tech fittings on boots such as TLT 5. Not sure why that is, perhaps because they are less concerned about ISO/DIN shape of sole, or perhaps just better design.

  71. Simon January 26th, 2011 3:59 am

    First picture of the new Scarpa Alien boot with the new DYNA evo at:

  72. tony January 26th, 2011 9:37 am


    When I wanted to resole my Zzeros, Dynafit USA reffered me to Rocky Mountain Resoles and Dave Page Cobbler. DPC had resoled my Megarides so I sent the boots to them. DPC said because of the indentation in the rubber caused by the quick step in toe fitting, they could not use any of the stock vibram soles they had to replace the Zzero rubber. I contacted Dynafit USA to see if they could sell me any Zzero rubber soles with the indentation built in to the rubber, but they said they were unavailable, even after checking with Europe. Rocky Mountain told me the same thing when I talked to them after DPC sent the boots back to me.

    Just talked to Dynafit USA, they say the yellow heel/toe rubber will be available as a spare part that you can send with your boots to a cobbler to replace the toe/heel rubber with.

  73. Brandon February 1st, 2011 5:50 pm

    Lou or Federico, any idea on the price of the new DyNA Evo? Similar to the current DyNA? Also is the last the same as the current TLT / DyNA, i.e. would the fit be the same?

  74. Ronald Cassiani February 20th, 2011 9:34 am

    Hi Lou,
    I am wondering if you have seen the La Sportiva boot line up for 2012. I know they also are distributing skis and a tech binding starting in December. The boots look quite innovtive to say the least

  75. Josa February 21st, 2011 3:20 pm

    Hi there, tried on my new Titans this weekend and a problem occured with my left boot. In walking mode it locked in skiing position when I leaned slightly forward, lever still in the upper walking position. Pushing the lever maximum up I could release to walking mode but when leaning the cuff forward in the stride it locks into skiing mode again. No problem with the right boot. Do I send them back to the shop or is there an easy fix?

    Thanks for your help

  76. olin February 28th, 2011 11:52 pm

    Thanks Lou, good advice (cheap gear thread). no mold yet on my Spirit 3’s so I threw in the TT liners and went for a ‘luge run’, I’m all smiles so far. My AT boot set has been a strange progression from my first somersaults with climbing boots on silverettas. In regard to boot evolution maybe the tele guys had a clue for long tours… a simple binding and a boot that flexes… but even one of my most diehard tele friends is threatening to convert b/c he can’t maintain his tele legs.

    I thought hard about the Scarpa bellows boots (F1/F3) and I’m really impressed at the incorporation of metatarsal flex in the TLT’s. The TLT seems like the real deal. Enough flex yet w/o the squishiness and need for shims, very nice! It just hurts too much to look at the price considering blisters might only be an issue for a certain long dream trip or two.

    Keep up the good work. I’m looking forward to some reviews on the new radical and wondering if the power towers will be compatible with the older boots.

  77. Jason Gregg March 11th, 2011 9:30 am

    Any idea when the 2011/12 ZZero Carbon Green Machine will start to show up over here? my original pair is about done and over in Europe now but I will wait until the new ones are out before buying a replacement.

  78. Skian March 11th, 2011 9:32 am

    August 2011.

  79. dg March 15th, 2011 1:22 am

    FYI Lou I am a ski boot guy here at BD and my first pair of real performance boots were the ski swap versions of the Competition 3f shown above… I suggest that we things have come some distance since then as well. 🙂

  80. Lou March 15th, 2011 5:50 am

    Insofar as ski boots coming a long way in 35 years, yes, they’ve changed quite a bit. But, I mean, 35 years? I’d really think we’d see more different stuff now. Perhaps so with boots such as Dynafit TLT5 series and Evo, but one has to admit how similar most ski boots are to those of 35 years ago, and really, how boring. I could take those 35 year old boots, fit them up, and ski in them just fine tomorrow. But try that on a 35 year old pair of skis. I’d sure like to see BD get as innovative and radical as Dynafit is with Evo and TLT5, at that point I’ll start thinking that yes, ski boots have really come along…

  81. Kjetil April 14th, 2011 3:32 pm

    Since you claim that the actual shell in the Titan Ultralight is so much lighter than the original Titan shell, why don’t you just weigh both shells and post the weights here?

    I replaced the stock liner in my Titans with Intuitions and saved almost 200 grams per boot.

    My guess is that the shell weights aren’t that much different (original Titans coming in at 1600gram – shell only – according to wildsnow!). Prove me wrong!

  82. Kjetil April 14th, 2011 3:34 pm

    Take the challenge, Federico! 😀

  83. Robin Taggart May 24th, 2011 5:35 am

    As long as they keep chipping away, I don’t mind if Dynafit are slow about evolving what they’re doing in boots. Slow and steady is good in my books; apart from anything else, it allows me to put a bit of wear and tear on my newest boots so that I can justify that spanky new pair in a couple of seasons’ time!! There’s nothing worse than having just laid out serious cash for new gear, only to find that they’ve completely re-hashed and upgraded the range the following season – you feel like you’ve be ‘done’!!
    Seriously though, I’m just back from the Italian High Level Route on the Swiss-Italian border (four days above 3500m) and I want to praise Dynafit for the incredible comfort and quality of their TLT Performance boots. The lack of weight is simply incredible; the feel and comfort they provide nothing short of revolutionary in skiing footwear. The pair together weigh less than one of my first alpine boots!! I have Titans, too – properly fitted and comfortable – which, although excellent, still feel like ‘ski boots’ on my feet; you are aware of their relative bulk and mass as you move. They have their place, especially on piste and just off it, on family holidays. But the TLTs: you could wear them all day; they’re like conventional footwear; slim, light and unobtrusive, with a natural progressive flex in walking, and yet enough support to feel confident and connected when skiing rubbish snow. They are a revelation!! If the future of ski touring footwear lies along this path, then any wait for it is going to be worthwhile!! So don’t rush them; give the Dynafit alchemists all the time they need to brew their secret formulas; in a few short years we’ll be thanking them from the top of our slopes and the bottom of our boot liners 🙂
    – “Oh Yes, I’ve found my moving buddies!!”

  84. Lou May 24th, 2011 6:33 am

    Robin, I’d agree. TLT5P is costly, but once you use them you understand just how much comfort and efficiency they add to your life as a backcountry skier. I have many boots I can choose from, and keep grabbing my TLT5s nearly every time I go out. I’ve lost count of the days in them, around 40 or so. My only real gripe is really don’t think they need the me tarsal sag, which reduces downhill performance while adding little if anything to uphill performance. But nothing is perfect, and like you say, all boots will evolve.

  85. Joel July 15th, 2011 3:39 am

    Does the Titan UL have vibram soles or just plastic?

  86. John Milne July 15th, 2011 11:26 am

    @ Kjetil – Both boots were 28.5’s w/ AT blocks, Titan UL’s used were preproduction demos.

    According to my scale, the Titan liner weighed in at 373g and the shell was 1716g for a total of 2089g.

    The Titan UL liner was 328g and the shell was 1541g for a total of 1869g and a difference between the two of 220g. 175g saved in the shell, 45g saved in the liner.

  87. John Milne July 15th, 2011 1:27 pm


    The Titan UL is the same setup as the regular Titan – Swappable rubber AT soles and plastic DIN certified blocks.

  88. Mark Schwartz August 29th, 2011 4:57 pm

    Is Dynafit producing both the Titan UL and a version of the 2011 Titan for the 2011-12 season? If yes, why would would select the 2011 Titan version over the Titan UL?

  89. Lou August 29th, 2011 5:08 pm

    Both Titan and Titan UL will be sold. UL costs more (that’s my recollection), which is one reason for choice… the boots no doubt have a slightly different feel between them as well, so a person might prefer one over the other for that. Lou

  90. James Brocklehurst August 31st, 2011 4:05 pm

    Can’t see any big difference between the zzeus and the Titan Ultralight. Is it just a few grammes or is zzeus a bit stiffer? Do you think they will ski the same?

  91. David November 6th, 2011 12:37 pm

    Lou et al,

    Have you figured out the difference between the 2011 ZZero green machine and the 4 C-TF? Worth the extra $200+? I’m looking for a lighter boot then my Zzeus. The TLT-5 wouldn’t fit my 3x surgically modified ankle and the Maestrale isn’t a good fit either (too big), so I guess I’m left with a ZZero, no? Garmont doesn’t look to have a boot in the Maestrale/ZZero class

  92. JasminD November 13th, 2011 5:22 pm

    Hey Lou –
    It’s finally time for a new pair of ski touring boots and I’m (attempting) to find some good beta on women’s boots, or at least men’s boots that come in smaller sizes. Much harder to come by good reviews about women’s gear in general it seems. I’d probably splurge on a green machine but it doesn’t come in a size smaller than a 25 🙁

    I’m currently skiing a Megaride with raichle tongues and intutions to stiffen up the boot. Looking for something stiffer and better downhill performance than the megaride, but still has to remain somewhat light (I can’t see the point of pairing up a super heavy boot with dynafits). Has to be a four buckle and my preference is for an intuition type liner.

    Scarpa Shaka’s or a Dynafit ZZero have so far interested me. Any other general thoughts / reviews that you know of that could be useful? (So far, local stores haven’t been helpful – can’t answer very technical questions). Cheers.

  93. olin November 13th, 2011 7:40 pm

    I have a pair of Scarpa Divas b/c they were the only thing I could find small enough (when I had money burning a hole in my pocket). They seem a little too soft with the touring tounge and stress fracture stiff with the stiff blacks. I longed for some cross between them and the heavy but comfy Denali’s so I got the Spirit 3; so far I’ve been pretty happy….23.5 Divas for sale.

  94. Don November 28th, 2011 4:05 pm

    Looking for some help trying to locate a A/T boot size 4.5 to 5 women’s. Most North America boots are 22.5 but with a 23 sheel. Hoping somebody might have contact or information to locate a smaller European boot. With Europe doing alot more A/T skiing that here in North America.

  95. Bob November 29th, 2011 6:01 pm

    Lou and others,
    Have any of you seen and better yet tried on some of the new ZZero full carbon Green Machines? I am curious because I do not fit the TLT5 very well, but I do fit the ZZero line. Is there a substantial difference between this boot and last year’s ZZero CF? I like the idea of a stiffer cuff particularly backwards and the additional range of motion theoretically provided by the full carbon version. With the full carbon cuff, I wonder if the forward flex will still be as progressive as the original green machine. Comments

  96. steve sellers January 2nd, 2012 6:00 pm

    Question on the Evos. I’m fortunate enough to have a pair on the way. With the race bindings there’s no adjustability, so I’m wondering if the boot sole length on the Evos is the same as what I currently have on the Dynas?

  97. Jonathan January 2nd, 2012 8:46 pm

    You know you’re just asking that question only to brag about having lighter race boots than I do…
    Anyway, my understanding is that the Evo has a different bsl than the original DyNA, but that it also doesn’t necessarily go in 10mm increments for every full shell size jump. So maybe it does match up at some bsl? (See the listing at Backcountry dot com for some examples.)

  98. Matthew January 2nd, 2012 9:52 pm

    Not sure about the DyNAs, but the Evo is shorter than the TLT5. My 2010/2011 TLT5Ps are 297mm; my 2011/2012 Evos are 289mm. Both in size 26.5 (and both feel the same size on the inside).

  99. Jonathan Shefftz January 3rd, 2012 5:38 am

    Ooops, ignore my comment on 10mm increments (or rather lack thereof) — I was confused by a TLT5 v Evo comparison somewhere else. The two boots apparently though have different shell breaks, i.e., 2X.0 and 2X.5 TLT5 are the same shell size, but I think the Evo goes 2X.5 and 2Y.0 are the same shell size.
    Also, I’m pretty sure Matt has the 27.0 in both those boots.

  100. Matthew January 3rd, 2012 9:09 am

    I think Jonathan is right- the back of the Evo liner says 270 on it. But, if you are going to drill race skis you should hold off. Both boots fit the same- the TLT5 was quite snug and required multiple rounds of punching on toes and heel. The Evo feels the same- if anything it will take less punching to dial it in, yet it is 8 mm shorter, so the last is different.. I don’t think most people will be able to swap boots without remounting race bindings (ST/FT/Classic should adjust fine)

  101. Jonathan Shefftz January 4th, 2012 8:49 am

    Is the interior length really the same for identical sizes with the Evo vs DyNA/TLT5?
    Even after two years I’m still astounded that my 265mm foot fits inside the 287mm bsl of my 26.0/26.5 DyNA & TLT5. I can’t see how another 8mm could be foregone for the same interior length (with a 279mm bsl) … but then again that’s what I thought about the 287mm in the first place!

  102. Matthew January 4th, 2012 7:55 pm

    Just measured my naked foot (heel against a wall, not with a Brannock device) at 284mm long, versus the 289mm BSL of my Evos. Magic!

    I had a pair of the Red Machine boots in my late teens. Best boots I ever had, but I grew out of them. Wish I still had them and they feet…amazing, soft, progressive flex but still secure.

    Really looking forward to trying out the superlight race stuff. I was debating a Dynafit setup or a Garmont Excursion/3-pin setup…and the Dynafit setup can be lighter, tour better, kick steps better and ski downhill better.

    Crazy…I remember doing the Haute Route on pins in 1989 because my Merrell Super Comp/Chouinard cable/Tua Expresso setup was SO much lighter than the AT gear of the time…and skied just about as good.

  104. Marlene February 1st, 2012 1:31 am

    In Europe they sell a women’s TLT 5 that’s white and green instead of off-white and purple. I wonder if yours is exactly the same boot?

  105. paul wunnicke September 27th, 2012 3:06 am

    How do this years’ Scarpa F1 and F! Race alpine touring boots compare with the 2009 Scarpa F3? Anybody know where I can get a pair of F3s size 26.0 Mondo?

  106. Lou Dawson September 27th, 2012 6:14 am

    Paul, the F3 and Terminator X have a much higher and stiffer cuff, and overall have quite a bit of beef. They are “real” alpine touring ski boots with a bellows. They weigh more than the F1 and don’t allow as much freedom when in touring mode.

    One could say the difference between the two is that the F3 and TX will feel like a regular backcountry ski boot, while the F1 may require some getting used to if you’ve not skied a more minimalist boot.


  107. paul wunnicke September 27th, 2012 9:32 am

    I am a former alpine area skier and have been skiing in the back country for almost 35 yrs. I have been using Merrill Super Comps for the last 25 years, still do. I have tried to make the switch to AT for safety reasons several times since the mid-90s. Every boot I have tried, most recently 2008 or so, has caused me to have Lange bang flashbacks from my racing days.
    The AT boots w/ bellows sound promising and a former pinhead friend of mine loves the Scarpa F3s. I want the most flexible(for the ups), best foot feel(for the downs) light weight boot I can find. Your recommendations?

  108. Lou Dawson September 27th, 2012 9:49 am

    Paul, preventing shin bang these days should be a simple matter of fitting and liner selection. Regarding bellows boots, lots of former telemarkers seem to like them, but I’d suggest just forgetting about the bellows as it’s totally not needed (as millions of AT skiers around the world prove every day).

    In terms of specific recommends, you probably need to get a bit more specific with your wants and needs, since every backcountry skiing boot out there is built to be flexible on the ups, have the best feel for the downs, and to be lightweight. (grin).

    But I’ll offer that folks are having great success with the Scarpa Maestrale and Dynafit TLT5 (which does have a slight forefoot flex), easily the two most popular boots out there. Here are the links:



    I like the Garmont Cosmos as well, but it doesn’t seem to be in the etailer channel yet. Also look at the Dynafit One.

    The above boots are excellent compromises between uphill and down. If you want something more on the down, the “freeride” type, that’s a whole other arena of boots such as Black Diamond Factor, Tecnica Cochise, and so on.

    Whatever you do, work with a good boot fitter. Fixed heel skiing is less tolerant of fitting and alignment mistakes, since you have less room for compensating movements (perhaps where your shin bang issue comes from).

  109. Ronald Cassiani September 27th, 2012 2:04 pm

    As a tele convert I think a bellows boot would suit you better. I notice that one gets better purchase (kick and glide) with bellows boots that with an AT herd shell.The bellows allows the ball of the foot to pressure downward onto the ski mimicking the kick of a XC ski technique. The resulting rebound powers the ski forward even with skins

  110. wick September 27th, 2012 3:00 pm

    Paul – I once tele’d too…go try on the Dynafit TLT 5 & SCARPA’s Alien …I don’t believe you will need the carbon version in either boot (its a stiffer upgrade for sure if you are still slightly charging in the BC), but these are your boots…especially if you are used to Super Comps! If you seek to ski powder in the BC these are your boots. I spent 5 years in F1’s and F3’s (hated the F3 compared to the F1 due to the lack of a natural stride in tour mode). I’m now in the Alien and DO NOT miss the bellows…even for mellow hut approaches…FWIW. Get the boot (between Dynafit & SCARPA) that fits your foot best!

  111. Lou Dawson September 27th, 2012 3:17 pm

    You guys might find it hard to believe, but I spent three years strictly telemarking, back when pins were pins, skis were toothpicks and men were men. I also did quite a bit of citizen nordic racing. Never missed the bellows, it is totally over rated and not something to sacrifice other features or performance for. Lou

  112. Lou Dawson September 27th, 2012 5:13 pm

    Lisa telemarked for one day. It’s a good story. Perhaps she’ll tell it some time.

  113. See September 27th, 2012 5:36 pm

    The phrase “foot feel (for the downs)” suggests to me that Paul W might want to make sure to get boots with adequate room in the forefoot (wide enough shells, molded with toe caps and maybe even padding around first metatarsal and 6th toe) to allow foot to spread and get that tele “big toe/ little toe pressure” feeling. Especially if he’s switching from 25 year old leather boots.

    Just my take as a sometimes (not often these days) telemarker with wide feet.

  114. paul wunnicke September 27th, 2012 11:35 pm

    Well I appreciate some of your insights and can feel the love of skiing vibe and anticipation for a new Winter. Here in AK it seems like it will snow tomorrow night maybe even later tonight.
    Lou, you might remember I took you on a tour in Turnagain Pass when you were researching your book. I think we also discussed the “S” couloir on Ptarmigan peak.
    While I have telemarked and still do every winter just because I can, it’s fun and every now and then even works better in certain heinous conditions; you all have made some assumptions. To wit: I am a free heel parallel skier and have been for 98% of the last 25 years. I still use pins. I don’t wear knickers or have a boda bag. My motto is: “if Tony Sailor and Jean Claude can do it, so can you!”
    Thanks for the tips!
    I guess I’ll be trying on a few pairs this Fall.

  115. See September 28th, 2012 12:13 am

    Have you tried leaving the cuff unlocked?

    Releaseable teles (7tm’s)?

    And I thought Jean Claude was a snowboarder.

  116. Lou Dawson September 28th, 2012 6:17 am

    Paul, so you were not the guy in the knickers (grin)?

    Still remember that tour up there on Turnagain, that AK trip was a big part of the genesis of WildSnow.com… Thanks!

    And then, the Ski Train.


  117. Matt November 12th, 2012 11:44 pm

    Hi Lou, Iv’e got a question for you about boot modifications on ZZERO boots. I’d like to do a punch near the inside ankle on a pair of ZZEROs and am trying to decide which model (if any) would be able to accommodate a punch. Unfortunately the punch needs to happen in the area of the stringer. My assumption is that the carbon stringer on the ZZero 4 C-TF would not accommodate a punch.

    Do you know if the rislan stringer on the ZZero 4 PX-TF would tolerate a punch?
    What about the polyurethane plastic on the ZZERO4 U – MF?

    Thanks for any help.


  118. Lou Dawson November 13th, 2012 6:19 am

    Matt, yeah, you’re not going to be able to heat mold that carbon with conventional boot tools. Anything in urethane, pebax or grilamid is moldable with good tooling and technique. Lou

  119. Matt November 13th, 2012 7:53 am

    Thanks Lou. Two more questions for you:
    1. Is rislan a type of urethane, pebax or grilamid?
    2. Is there a non conventional way to mold carbon? What is it?
    Thanks again,

  120. AVIATOR November 13th, 2012 9:14 am

    @ matt
    About molding composite parts, no it’s not possible.

    You might hear stories about people kind of doing it but that’s when they had an incomplete cure for some reason, the epoxy didn’t go 100% hard in the first place.

    And they will have caused stress, cracks and fractures to the part and it will be a LOT weaker even if they THINK they did a great job.

    Carbon boot parts are made in autoclaves, and the epoxy is perfectly cured and post cured. They cannot be reshaped.

    You have to replace the composite part, or at least part of it.
    The beauty of composites is how you can epoxy glue them, repair them and keep adding on to them.
    You cant do that with polyamids, whether it’s grilamid or pebax.

    To punch a carbon boot, you have to drill/saw a hole where you want to expand, then add new fiber and resin on the outside, repairing it but with a new and slightly different shape. That’s the only way.

  121. David Morissette November 22nd, 2013 11:56 am

    Great review!

    I am wandering if the Zzero Green Machine have a similar (or the same fit) as older versions of the Zzero. I’ve own a pair from 2008 or 2009 of regular Zzero, not the ones with the carbon reinforcement. I’ve always love them and i’d like to get a similar fit with my new boots.


  122. Lou November 22nd, 2013 1:29 pm

    I’m 999 sure that both versions have the same exact last.

  123. Vt February 19th, 2014 9:51 am

    Anyone had a problem with the carbon cuff slicing through the back of the boot liner? Just noticed this lately. Did a number on the backs of some more comfortable and better performing liners I replaced stock Palau liner that came with boot. Have gone back to stock liner because I don’t want to further damage my other liners that I use in another boot. Not being materials scientist, I hesitate to attempt to file the edges. Haven’t checked with Dynafit about this yet, but it’s pretty bad.

  124. Billy Balz February 19th, 2014 10:00 am

    @vt, yep it’s happening to my liners as well on tlt6p. I’m wondering how bad it will get and whether it’s a cosmetic issue with no performance ramifications. I’ve only skinned 20,000 feet so far and done about 5 resort days. On mine it’s ripping/fraying the yellow piping away from the lower material. It seems cosmetic but too early to tell.

  125. Dave January 31st, 2015 2:47 pm

    Lou, I have been skiing a pair of Dynafit ZZero4 PX’s for the last few years. An incredibly comfortable and light boot that I can wear for a week in BC with nary a sore spot. I currently use them to drive Voile V8’s with Radical ST binding. A nice light setup. Unfortunately I find the boot “cold”, and on the soft side. All day trips in weather below 10F are numbing experiences and the occaional powder day at the area is a little random. Is there anything I can do to make the boot warmer (I ski them with Superfeet already) like new liners and any tweaks to make them a bit stiffer? Or is it time to face reality and pony up for new boots? If so what would you recommend for all around boot that would be fairly light, moderately stiff and warm?

  126. Daniel February 16th, 2016 1:02 am

    Hi there

    I ski the Green Machine boot pictured above- the one with the ful carbon cuff. Great boot!

    Recently on of the walk machanism levers fel off and got lost. Dynafit Europe seem to have severe problems finding a spare part.

    Anyone got an idea? Or maybe a lever?


  127. Daniel February 17th, 2016 1:03 pm

    bump…I’m desperate…

  128. Lou Dawson 2 February 17th, 2016 3:57 pm

    Daniel, can you work with a machinist or hobby fabricator and make a part?

  129. Daniel March 21st, 2016 1:34 am

    Dynafit eventually made me an aluminum spare part! good job! hooray!
