The object at hand: TLT-7-P ski touring boot.

I’m amazed and delighted by this shoe. Firstly, I’m here to tell you that we have in the TLT-7 much more than a model iteration. This is easily one of the most innovative boots to drop in the last few seasons. It’s like a Tesla coming after a Prius. From the one-motion mode change that actually might be best-ever, to the chop toe, to the through bolted heel fitting, super.

But more, let me brag. This boot incorporates a goodly number of TLT boot hacks and innovations we’ve made here in the WildSnow mod shop over the past decade. Yes, imitation is the sincerest form of flattery. Thanks Dynafit! Let me count the ways, with linkage to some of our mod posts.

1. Through bolted heel fitting.
2. Relocated instep cable pressure. (we relocated the lower buckles on all my former TLT boots.)
3. Hinged tongue (I added a small hinge from the hardware store to my first pair of TLT-5).
4. Possibly less wear-prone cuff pivot rivets (designed with Bill Bollinger).
5. Wider forefoot box (we’ve been punching out TLT boots for years).
6. Optional power strap (in retail box but not attached.) We almost always removed.
7. Lower buckle that doesn’t catch or open during snow or rock climbing.
8. Total elimination of vestigial buckles at the toe of boot (old news, but belongs on the list since we got a lot of grief for ripping the lower buckles off 4-buckle boots.)
9. Grinding duckbill toe off boot to the greatest extent possible. (We couldn’t produce a “Shark Nose,” but we tried.)
10. Modification of Ultralock plate to change forward lean.
11. Elimination of metatarsal flex in the first generation TLT (us and blog contributors).

Okay, I got to brag. Moving along…

First, let us put one question to bed. Is the TLT-7 last wider than the TLT-? Definite answer is yes, comparing my TLT6 with punched out metatarsal, the outside width of the 7 is still 3 mm wider. According to Skialper Magazine, which actually measures the last width of a 27.5, the TLT6 has a 99.5 mm internal width, while the 7 measured at 100 mm. That doesn’t sound like much (and makes me wonder if Skialper might have changed their measurement methods), but every bit can make a difference to sensitive feet. More, in real life terms they reshaped the TLT last significantly, especially in the toe area and over the forefoot. Comparative testing of this is easy, you just shell fit each boot on a stocking foot. The 7 clearly feels overall more roomy. In my opinion it’ll be easier to fit and warmer, while not being so commodious as to bum out those of you who like narrow lasted boots.

(Podiatry teaches us that the foot is actually something like a “sack of bones” and squishes around to use additional shoe volume that’s not always in the exact spot you would assume. In other words, while the specific last width might not be all that much wider in the 7, the overall increased volume can make it feel significantly more commodious. Adding to that, the 7 has less layering of plastic getting in the way of shell width “punching” modifications, as well as still using easily heat adjusted Grilamid plastic.)

Ankle width of the 7 is slightly wider as well. I compared using my interior dimension caliper, which doesn’t give me exact millimeters but does yield good visual evaluation. Measured outside with my external caliper, the 7 is about 3 mm wider than the 6. (Remember outside boot measurements are dependent on thickness of shell plastic, so they’re only a rough guide.)

Weights are interesting. My 27.5 TLT-6-P (shell only) with power strap and without add-on tongue comes in at 958 grams, while TLT-7-P shell comes in at 882 with power strap (it has a permanently attached tongue). That’s a significant difference in mass that’s even greater when you add the “real” tongue to the TLT-6-P. Takeaway here is Dynafit clearly made a boot model upgrade that doesn’t suffer dreaded “weight creep” that sometimes happens in lightweight ski touring gear.

Big deal with weight here is ourselves and others in the industry have informally created a “category” of “real” ski touring boots. Big criteria is weight around one kilo per boot. TLT-7 is right in there. Our sample 27.5 without power strap but otherwise fully configured come in at 1,018 grams per boot.

Note we tend to do boot weight comparisons without liner installed, as many skiers add multiple liner customizations or simply swap out the liner for something they like better. Be that as it may, rest assured that the 7 liner is about as minimalist as you can get (164 grams with stock footbed). Its weight is not an issue.

Hidden cable routing for one motion buckle operation.

Hidden cable routing for one motion buckle operation. The upper buckle is actually two buckle levers that work either independently or in concert (see video and more photos below). While we do like this setup, it’s perhaps a bit over hyped. Reality is that the TLT 5 and 6, when set up correctly, can easily be switched between up and down modes by flipping the one upper cuff buckle. Difference here is not only does the TLT-7 buckle remain low profile (it doesn’t stick out from your boot like a tree branch), but the the 7 buckle system also opens the entire boot with one flip of a buckle and a little pulling at the closure cable loops. Perfect for when a skier needs hypothermia treatment and you need to quickly jump into a sleeping bag with him or her. (Seriously, any added convenience in ever fiddly ski tour gear is welcome).

The hidden cable operated closure system needs exposition. It looks more complex than it is. Upper cuff buckle is actually two levers. One (black) is attached to the cuff closure cable loop and can be operated independently, the other (greenish anodized aluminum) is attached to a cable routed down to the instep closure over the tongue. When you first don the boot to begin a tour, you buckle with the black buckle which puts you in downhill mode. Adjust all your tensions so they feel good for down-skiing, then simply flip the upper black buckle out, which opens and releases the cuff for touring.

Ideally, throughout the day, simply flip the black buckle to go from downhill to uphill mode and back. Long term testing needs to occur, but for now I’m truly impressed by this system. The upper buckle(s) is much more low-profile than the TLT 5 and 6, and also entirely opens your boot with one motion (more on that below).

The 'double buckle' of the TLT-7

The ‘double buckle’ of the TLT-7. Black controls only the upper cuff. Once you enter the boot and everything is adjusted for the day, you just flip the black open and closed to switch between uphill and downhill modes. When you flip the black to uphill mode, it releases the green buckle from the lean lock by lifting the green buckle a few millimeters. Ingenious. They call this whole system Ultralock 3.0. It continues to use the Dynafit patented and beautifully simplistic lean lock consisting of a small aluminum tang on the buckle, that inserts in a hole at the rear of the boot cuff. Clearly still one of the best lean lock systems in the industry.

Ultralock 3.0 open for touring.

Ultralock 3.0 open for touring. Said again, making this move lifts the green buckle up out of the lock hole at rear of boot cuff. The instep buckle remains snug with perhaps a nearly imperceptible easing. Using this system for a truly one-motion switch between up and down modes requires properly fitted boots, as you’re limited to one instep buckle setting that doesn’t snug up for the down the way people tend to do manually. Update per reader comments: Note the small black cord loop coming up from front of cuff. This is intended to position the power strap and needs field evaluation.

The 'double buckle' of the TLT-7

The ‘double buckle’ of the TLT-7. In this photo you can see how lifting the black buckle lifts the longer colored buckle tang out of the Ultralock lean-lock opening. This photo shows the somewhat short liner spoiler that could cause comfort problems for some folk’s calf shapes. Easily fixed with boot fitting skills or aftermarket liners.

Ultralock 3.0 uses same interior aluminum plate as ver 2.0, you can flip this for more or less forward lean by a few degrees.

This TLT boot does not a removable or add-on tongues.

This TLT boot does not have removable or add-on tongues. Instead, a permanently attached tongue not unlike that of the TLT-6 is hinged for easy entry and exit. In the way of many modern ‘tongue’ type ski touring boot shells, TLT-7 depends on the rigid rear spine of the shell for resistance to forward flex, rather than depending on how stiff the upper part of the tongue is. It would be trivial to mod this by adding a plastic layer to the tongue, but in my testing I see little need for most skiers to do this, due to how well the shell resists bulging at the cuff pivots, which is the mechanism by which these type of boots ‘collapse’ forward under aggressive skiing.

Opened up for entry, note the hinged tongue.

Spine and outside of boot lower shell are reinforced with a fiber composite molded in with the boot plastic.

Spine and outside of boot lower shell are reinforced with a fiber composite molded in with the boot plastic. This all appears more sophisticated than TLT-6-P though we doubt it skis downhill any better. Which is not a criticism, as the 6 does the job quite nicely. I do wonder why they didn’t build the fiber composite into both sides of the scaffo, as during carpet testing you can clearly see how doing so would have contributed to ever more stiffness by preventing bulging. Or? A ‘tongue’ boot can be too stiff. Perhaps Dynafit did this intentionally to tune the forward flex.

Dynafit 'certified' fittings are indicated by this clip-on seal.

Dynafit ‘certified’ fittings are indicated by this clip-on seal. Is this a big deal? Depends. If you know what you’re doing, or working with a competent ski shop, binding release and retention can be evaluated in such a way as to give the nod or nix to any given boot fitting and binding combo. On the other hand, the boot fittings in the tech system are very much a part of the binding mechanical systems. Without an industry DIN/ISO standard for the fittings, some sort of standardization can be valuable. I don’t want to write another thousand words on that issue here, as we’ve already written 500,000 words on it. Try this site search.

Dynafit uses their new toe fitting version they call Master Step.

Dynafit uses their new toe fitting version they call Master Step. These are intended to make binding entry easier while preventing accidental release at odd angles. I’m of the opinion that experienced users will be fine with any version of tech fittings, while Master Step is helpful for newcomers to the tech system.

Only real downside to the Master Step is the added size eliminates room for more boot rubber, thus creating a wear prone spot for people who do a lot of hiking or rock scrambling in their ski boots. For that reason, I have a constant itch that will only be scratched when Dynafit goes back to the old style fittings in their high end boots. But that’s probably not going to happen. It would be like that Tesla dragging a 2-inch receiver hitch.

This is big. Heel fitting is attached using a through-bolt type of fastener from the inside of the boot.

This is big. Heel fitting is attached using a through-bolt type of fastener from the inside of the boot (this can be viewed by simply pulling the liner and looking down inside the boot heel area). I’d actually call this the uber feature of the TLT-7, as it probably eliminates an inconvenient or downright dangerous failure mode.

Comparison of TLT-6 toe box (r) and TLT-7.

Comparison of TLT-6 toe box (r) and TLT-7 widths, you can clearly see the extra volume of the 7. Toe box of 7 is slightly higher as well.

Instep closure is via wire cable and an adjustable ladder ankle.

Instep closure is via wire cable loop and an adjustable ladder ankle. This system gives much better pressure distribution than TLT-6 as well as locating one of the cables up higher on the instep for that ‘locked in’ feeling many of us desire in a ski boot; that’s not well provided by having one buckle lower down on the shell over your foot arch.

Shell closure flaps include a mysterious black cord loop.

Shell closure flaps include a mysterious black cord loop. This is intended to solve the ubiquitous problem of power straps riding up too high, and also keeps the power strap from being tangled inside your pant cuff. We’d recommend trying this boot without the power strap, as using the strap kind of makes a mockery of the ‘one motion’ mode change system. (This photo is the Dynafit ‘Expedition’ model boot, not the TLT-7).

Other thoughts: Yes esteemed WildSnow readers, you can’t use “toe bail” style crampon on the 7 without an adapter. On the other hand, perhaps this will encourage crampon makers to build spikes that utilize tech fittings for attachment, such as the Techcrampon 250, (Which is said to work fine so long as you order the current version.) Another concern with TLT-7 is the liner being rather short at the rear shell spoiler. This could be uncomfortable for folks with certain lower leg and calf shapes and require an aftermarket liner or boot fitter mods. In terms of weight, just as with skis a big marketing target for ski touring boots is ONE KILO! Obviously, the 7 reaches that target in fine style. Thumbs up.

Metrics and specs:
Official weight, industry standard sample size 27, 1,010 grams.
Weight of our 27.5 testers, no power strap, 1,018 grams.
Women’s model? This boot is unisex, as most if not all ski touring boots actually are — other than color stereotypes.
Plastic type is Grilamid, so ease of heat punching will continue.

Shell breaks
(22.5) (23 – 23.5) (24 – 24.5) (25 – 25.5) (26 – 26.5) (27 – 27.5) (28- 28.5) (29 – 29.5) (30 – 30.5)

As always when it comes to ski touring boots, we recommend several boot shopping options. If you know what you’re doing, etail can work. Backcountry.com has ’em. Otherwise, seek out a local shop. Our website financial supporter who loaned us our evaluation boots Cripple Creek Backcountry is a good example, to find a “real” shop near you see our Best Ski Shops post.

    According to Fritchi, this boot is not compatible with the Vipec binding. Lou, can you confirm this?

  2. Andy Carey November 28th, 2016 9:34 am

    Looks like the shell breaks have changed, so the size guide on Backcountry.com is off. And, for me, would necessitate visting/buying from a shop as my foot is a little between 29 and 29.5; I might actually get a better fit with the 28.5-29 shell or perhaps too short a fit. I have actually liked the CR liners in my 5s, 6s, and Mercuries. I couldn’t use my Intuition Pro-tour in my 5’s but I can in my 6s. Any comments on how the 7 liner compares to the CRs and the Intuition. Sounds like it might be quite thin?

  3. See November 28th, 2016 10:00 am

    Nice looking boots, but I don’t get what the advantage of the blunt toe is, especially given the crampon compatibility issue it creates. I’m guessing the carbon stiffener is only on the outside of the boot lower to allow for navicular punch.

  4. NT November 28th, 2016 10:18 am

    What’s the BSL on the 27.5? Looks like it’s going to be shorter than the TLT6.

  5. jay November 28th, 2016 11:02 am

    So what crampons are people using and having success with when using these boots?

  6. Paul November 28th, 2016 11:23 am

    The amount of detail provided for this boot (and other Dynafits) in comparison to a Zero G boot or similar boot is a bit laughable. Shocked Dynafit isn’t buying all the ads on this site as well.

  7. Ben November 28th, 2016 11:52 am

    I’ll take the Tesla over the Prius no question, but this is no Tesla in terms of aesthetics. Ugliest boot ever.

  8. Eric Steig November 28th, 2016 11:58 am

    A real annoyance with the TLT 5 was the that power strap could easily ride up and off the front of the boot. Also true (though less so) with the TLT6.

    Does the TLT7 solve this properly?

    (Another mild annoyance I’ve always had is that sometimes I would like the boot to be in tour mode, but with the top buckle still engaged. If the power strap is any good, that would largely this problem.)

    Thoughts on this, Lou?

  9. Eric Steig November 28th, 2016 11:59 am

    I guess you address this actually:

    “When you first don the boot to begin a tour, you buckle with the black buckle which puts you in downhill mode. Adjust all your tensions so they feel good for down-skiing, then simply flip the upper black buckle out, which opens and releases the cuff for touring.”

    So in short, you can keep the upper part of the boot tight, but still stay in tour mode?

  10. Lou Dawson 2 November 28th, 2016 12:02 pm

    Andy, I got the shell breaks off the Dynafit site figuring that was a solid source and their punctuation messed me up. I fixed, apologies. Regarding finding out for sure about Vipec, that would probably for sure allow me to sell every ad I have to Dynafit, per Paul’s suggestion, so I’ll get on it. Am already planning the Cortina ski vacation I’ll be able to afford.

    See, the blunt toe has several advantages I know of. 1.) Perhaps occasionally works better in the vast variety of tech binding out there that some boots might have trouble with when toe configuration is wrong shape for binding. 2.)Weight. 3.)Looks excellent next to your Tesla.


  11. Lou Dawson 2 November 28th, 2016 12:05 pm

    Eric, NO, I tried to figure out a way you could use the boot at downhill tightness without the lean lock engaged. I had high hopes for this, but alas, not a feature I could find. If I’m wrong, then all the more reason for Dynafit to buy more advertising (smile.)

    The idea with buckling down the boot during tour start is simply to get your downhill tightness adjusted so you don’t have to change it at the top of the tour, instead you simply flip the black buckle. Similar idea to any other boot one attempts to configure for “one motion” mode changes, a la skimo racing style.

    Re the power strap, I couldn’t see how the shell or liner were high enough to prevent the slippage to which you refer. Clearly, the boot is intended to be used without power strap if possible. Many European boot designers in my opinion have never had much truck with power straps… eh?


  12. Arnie November 28th, 2016 12:40 pm

    Surely the old “piece of tube” over the lean lock will still work for a tight cuff with ankle “unlocked”?

  13. SteveR November 28th, 2016 2:08 pm

    If a pair of skis has non-adjustable race bindings, and is set up to accept a TLT6, can you use the same ski with the TLT7 without redrilling? I could compare BSLs to try and work this out, but the lack of a toe welt on the TLT7 would make a comparison of BSL with the TLT6 irrelevant.

  14. Dave Place November 28th, 2016 4:09 pm

    Thanks for the TLT-7
    tech insight (& brag!)

    My feet & 50ish legs are in the market for new
    boots, especially those approaching the one kilo.

    Any thoughts on
    comparing the Atomic Backland Carbon, Arc’teryx Procline Carbon & TLT-7P especially regarding
    heel pocket fit & a moderately stiff progressive flex ?

    With the PNW getting pounded & snow on its way this week to most of the west let the real world testing begin… 🙂

  15. jbo November 28th, 2016 4:53 pm

    @Eric & @Lou – There is a little loop of cord on the upper buckle catch through which you feed the power strap to prevent it from riding up. Simple and works great. You could use it to close the top while in tour mode.

    @Andy & @NT – The shell break is the same as the TLT5/6 while the BSL is ~4mm shorter in the same size (e.g. 27.5 is a 293 vs 297).

    @Lou – The women’s model has an upper cuff adapted to a female calf. It’s not bigly different.

  16. jbo November 28th, 2016 5:01 pm

    @SteveR – The BSL comparison is not irrelevant since the toe fittings are pushed back to the standard distance from the toe. This is a feature of the 7 in that the fittings are closer to the natural pivot point of your foot, making for a more efficient stride. That said, the effective tech-length difference is more like 3mm versus the 4 you would expect based on the indicated BSLs. Definitely cannot reuse a fixed-race mount though.

  17. Eric Steig November 28th, 2016 5:29 pm

    Lou Dawson 2, thanks for the clarification regarding the boot tightness and power strap question. This is too bad, because I have found times when this is what I want — e.g. when going up and down rolling terrain where it’s not worth locking in (faux telemarking, if you like). Makes the Atomic Backland series attractive.

  18. Eric Steig November 28th, 2016 5:30 pm

    @Jbo, thanks for that tip on the cord for keeping the powerstrap in place. Not very impressive. Scarpa has had this figured out for years; too bad Dynafit still doesn’t get it!

  19. Lou 2 November 28th, 2016 6:22 pm

    Guys, I totally 100% missed that about the cord loop for the power strap. Selfie face slap. Does seem a bit manky but it might actually a good solution because otherwise the strap is always getting moved around during touring when it’s loose, or at least that happens to me nearly every time I got to fiddle around with getting into downhill mode. I’ll install a power strap and get a photo. Good catch. But, wait, they left the straps off for a reason? Lou

  20. Lou 2 November 28th, 2016 6:25 pm

    JBO, I compared toe fitting location of my 27.5 TLT-6 with that of the 7, no difference. Or should I look again? I was thinking it was indeed different, was surprised it was not as I’ve always liked the idea of the fittings being located a few mm back. I just held the soles of the two boots together, should I measure with method other than that? Thanks, Lou

  21. Lou Dawson 2 November 28th, 2016 6:43 pm

    The “tubing on the tang” Lock Blocker mod would probably work fine.


    Lo and behold, in the post linked above you can see my hinge mod on the TLT tongue! I was looking for that photo and couldn’t find it. Rather amusing. Worked well.


  22. Greg November 28th, 2016 6:54 pm

    I will stick with my Prius. Unlike a Tesla it has a 500 mile range and is easily and quickly refueled at just about anywhere, while costing less than 20% as much. And, it is not powered by coal.

    On the other hand, I want these boots.

  23. Blake November 29th, 2016 10:06 am

    Lou – I feel like I get a lot of use out of a traditional toe when primarily when making kicksteps in firm snow (but not icy crampon firm) and don’t think these boot would be as effective. The typical protruding toe also keeps my toes away from impact when kicking in firm snow and rocks.

    Your thoughts?

  24. Doug November 29th, 2016 10:41 am

    “I tried to figure out a way you could use the boot at downhill tightness without the lean lock engaged…but alas, not a feature I could find”
    ” This is too bad, because I have found times when this is what I want — e.g. when going up and down rolling terrain where it’s not worth locking in (faux telemarking, if you like). Makes the Atomic Backland series attractive.”

    …and the Mtn Lab, and the Procline…

    For everybody but racers, I feel the one buckle lean/lock thing that both Dynafit and Sportiva use is a bad idea. I do a lot of semi-technical climbing in my AT boots so not being able to snug up the cuff in walk mode is a deal breaker. Sure, you can do the tubing trick, or you can upgrade to a Procline, Backland or Mtn Lab boot. Don’t know anyone who has ever wanted to return to buckle/leanlock combo after trying one of these three competing boots.

  25. jbo November 29th, 2016 2:24 pm

    @Lou – I put the boots into a binding and measured the difference in heel gap at about 3mm for the 26 shells. Not much to see by just eyeballing.

  26. Ed November 29th, 2016 2:49 pm

    I agree with the lock-in comment – I use this “mode” a lot in tours thru the timber here in Alberta. What I did on my old reliable TLT5’s is use half of a plastic grommet – I have them on a little string tied to the lever and the grommet hole is the right size to easily press onto the boot’s locking tab but doesn’t go anywhere or let it lock into downhill mode – this gives me lots more support for undulating terrain (hoiking it over downed trees, beaver dams and critters) and then down the little dips, especially when carrying a pack.
    Typical grommet package (cheap) is at:
    Maybe this’ll help?

  27. harpo November 29th, 2016 10:31 pm

    One of the things I liked about the TLT6P (green) was the contrast between downhill mode and tour mode. With the removable tongue installed and power strap tightened, the flex was stiff enough for me to ski as aggressively as in my downhill boots, albeit, the flex wasn’t as progressive, I am fat, I am not a racer, and I don’t catch much air. In tour more with the optional tongue removed, the TLT6P didn’t feel very different in terms of ankle mobility from my long gone plastic mountaineering boots. How does the 7 compare to the 6P in this regard? For that matter, how do any of the AT boots currently on the market compare in this regard? I know you can find boots that tour as well as the 5/6P, and boots that ski as well as them in full downhill mode, but can you find that in the same boot? My guess is that the removable tongue was the key design feature that provided that mode contrast. I might be wrong though, I haven’t tried on any new AT boot since the green 6P came out.

  28. Eric Steig November 30th, 2016 8:12 am

    Lou, I have a not-totally unrelated question about dynafit gear this year.
    You reviewed the Cho Oyo a couple of years ago, and then the Carbonio 88 this year, but you didn’t compare them. Are they actually very different (other than price)? They are about the same dimensions and weight, it seems.

  29. Lou Dawson 2 November 30th, 2016 9:20 am

    All, thanks to JBO I paid attention to the “black loop” on the cuff of the TLT-7 and other of this year’s Dynafit boots. Added photo and text to the blog post. If you do use a power strap, I think the loop is a good idea. If nothing else it’ll prevent the power strap from getting tangled up in your pant cuff when loosened or undone for touring mode, and perhaps it’ll keep the strap located where you want it while you’re in downhill mode. Lou

  30. Lou Dawson 2 November 30th, 2016 9:24 am

    Eric, I can tell you that they are quite a bit different, but I don’t recall details as, wasn’t it Louie who skied the Carbonio? I’d ask him but he’s on a raft in the Grand Canyon at the moment. Overall, I’d offer that lightweight “narrow” skis have really improved in the last couple of years, with companies such as Volkl pushing it with the VTA 88. Thus, while I like the Cho for what it is, I’ve already moved on. Lou

  31. Chris December 1st, 2016 7:28 am

    Excellent piece Lou, thanks.

    Like Harpo, I am a great fan of the big forward and backward motion of the 5 and 6 with their tongue out.

    How does the 7 compare? That fixed tongue looks severely restrictive!

  32. Lou Dawson 2 December 1st, 2016 8:55 am

    Chris, same mobility, the fixed tongue is not much, it’s similar to the faux tongue of the 5 and 6. The 7 tongue could easily be detuned even more, but I don’t see the need. Lou

  33. harpo December 1st, 2016 2:33 pm

    Indeed, a maggot on TGR who has tried on the 7 says it is comparable to the 5/6 in both ski mode and tour mode. Pretty damn cool. I can’t wait to wear out my 6’s but with my new newly married life style that isn’t going to happen anytime soon.

  34. Chris December 2nd, 2016 12:47 pm

    Thanks for the quick answer Lou. In reading my question I realised I had actually wanted to ask 2 questions relating to forward and backward motion: 1/ how much movement is there backwards and forwards with and without tongue (i think you answered that one)? and 2/ how much additional friction in the backward and forwards movement is added by the tongue?

    I know that from my experience with the TLT5s, I often took out the tongue because i felt a significant difference with and without tongue. I am guessing that this is because I rarely pivot my rear bindings and stay on the lower ramp setting for a much broader range of slope angles than I should (i.e. i probably lean forward into my TLT5s more thanI should on steeper terrain).

  35. Martin Volken December 2nd, 2016 1:58 pm

    Hi Louie;
    Great review for the TLT 7 boot. I would like to make one correction though. The Techcrampon 250 works just fine with the TLT 7 boot. We made one minor modification (essentially opened up the bumper angle by 2 degrees) and now everything fits very well.
    It is important that folks who want to purchase the crampon for a TLT 7 boot specify that in their order, since those crampons are modified a bit.
    Thank you. Martin

  36. Lou Dawson 2 December 2nd, 2016 2:31 pm

    Thanks Martin, super information, I’ll add to the review. Could you email me a photo of how the Techpon attaches to a boot with no toe ledge? I’m mystified. ‘best, Lou

  37. Martin Volken December 2nd, 2016 2:35 pm

    it works because the toe ledge is has no structural function in keeping the crampon in place in the event of a trip. This gets taken care of by the rubber sole. I will email you a photo.

  38. Lou Dawson 2 December 2nd, 2016 3:32 pm

    Thanks Martin, I updated. I’ll probably publish the photo. Louie of course has our Techcrampons, hence I didn’t get hands on to fit them to the 7. Thanks, Lou

    Bought these boots sight unseen this year, just finished up 2 days on them. One day of lift accessed backcountry yo-yo ing and one full backcountry day. Driving big(ish) skis with them – BD Helio 116 Carbon.

    They are very very light, very low profile boots. the buckle system secures your heel very well, toes, not so much – lots of wiggle room there. They are fairly stiff too! not much flex at all for such a light touring boot.

    The liners – are very minimalistic, and very low on my calf. I can see myself putting a higher intuition liner in it to bring it up to a higher level.

    All in all – very satisfied (except with the liner).

  40. Lou Dawson 2 December 5th, 2016 5:10 am

    Thanks for the contribution Don. I’d agree, if the liner were only a centimeter taller it would be much better. But they do function. A boot fitter can mod and there is indeed always the aftermarket liner option, especially now that the toe of the boot is not so small. Lou

  41. eggbert December 5th, 2016 12:49 pm

    Was there any answer to the question re: the TLT 7 compatibility with the Vipec binding? I’m assuming it is due to the reshaped toe and forward release of the Vipec.

  42. Lou Dawson 2 December 5th, 2016 12:54 pm

    Eggbert, the release of the Vipec has nothing to do with the shape of the boot toe or even that of the heel. It works off the boot’s tech fittings. The only question would be how the boot does when entering the binding. Someone will probably chime in here. If not, I’ll check out that combo sometime today or tomorrow when I’m out doing errands. Thanks for bringing it up. Lou

  43. eggbert December 5th, 2016 9:28 pm

    Thanks Lou for chasing this down. I looked at the Diamir site and they put the burden on the boot maker/buyer to check the fit. I think the standards horse has been beat to death so no need to resurrect that topic.

  44. Bob December 6th, 2016 8:51 am

    It seems to me that the shape of the boot toe on the TLT7 could potentially impact the function of the Vipec binding. In skiing mode the boot toe has to depress the toe lever to open the pins to allow release in a forward fall. In tour mode the shape of the boot toe is supposed to eliminate the opening of the pins. This is all accomplished by different shapes of the plastic inserts that go in the toe lever. I don’t have this boot to test out the different toe lever inserts to see if any of these inserts will work effectively with this boot. Fritschi Europe told me a no go with the TLT7, but would love your take.

  45. Lou Dawson 2 December 6th, 2016 9:00 am

    Ok, thanks Bob, I’ll look at it. You’re probably right. Lou

  46. Lou Dawson 2 December 6th, 2016 12:09 pm

    Ok boys and girls, I spent an hour fooling around with a Dynafit “shark nose” boot and the Vipec Black, no go. It either bumps into the toe lever too soon in touring mode and opens the binding, or else it doesn’t bump into it correctly during a forward release and thus a complete binding exit during forward release would be compromised. I tried it with all three sets of toe bumper clips, as well as without a clip. That is all. Lou

  47. eggbert December 6th, 2016 3:29 pm

    Well, I guess job security isn’t something you’ll have to worry about Lou. Thanks for the test results.

  48. Ron December 25th, 2016 8:00 am

    Hi Lou,
    Just finished my first tour on these things. Incredibly light and good fitting. The single buckle system seems to work for me although I kept looking for more buckles to latch out of habit. I’ll second that the cuff is stiffer than expected although a little low.

    Do you have any ideas on where to latch a dynafit leash?

    Also, are there any concerns with wear on the cuff hole where the latch tang passes through?

  49. Matti December 28th, 2016 10:36 pm

    Just got these boots last week. Out of curiosity I tried to fit these to my beast 14 bindings since they were advertised that the insert is not needed anymore. I wasn’t able to fit those correctly, the claws above the heel pins were touching the boot frame way too early and I wasn’t able to get the “kiss gap” between the binding & boot. I wrote Dynafit about this issue, but still haven’t got any reply.

  50. Lou Dawson 2 December 29th, 2016 9:28 am

    Matti, where did you see it advertised that the TLT-7 would fit the Beast? Perhaps they have a new version of Beast coming out that doesn’t have the “claws.” Otherwise, I don’t get it, as your testing revealed what I would assume would be the case. Lou

  51. Matti December 29th, 2016 9:32 pm

    Lou, from their website. (http://www.dynafit.com/us/tlt7-performance-boot.html) and then from there the section Features -> and then click the Master Step. The text says ” Automatically compatible with Beast binding” I know that this is related to Master Step, but I think that should not be advertised like it says for TLT 7. Same is also in the evo.com
    Anyhow I’m not worried because I’m using MTN LAB boot with the Beast and TLT7P with my ATK Raider 12 2.0 & ATK SLR Release bindings. Just saying that their advertisement is a bit misleading.

  52. Andre January 2nd, 2017 1:10 pm

    Hi Lou. I am currently in the Dynafit One as I generally prefer a softer boot, with an Intuition Plug liner which stiffens it up a wee bit. I am excited about the new TLT7 as first try carpet testing offers little to no instep pain (I have a nightmare high instep and wide forefoot though high volume boots are too roomy everywhere else). I am considering buying these TLT7 Performance or Carbonio boots though wonder if they will be too soft for the downhill. What is your estimate of the infamous subjective flex on these TLT models? 110 perhaps? So I wonder if they will handle the downhill alright even for this contributor who likes something a little softer than super stiff? I’m about 190lbs and getting lighter. Cheers mate!

  53. Lou Dawson 2 January 2nd, 2017 3:17 pm

    It’s easy to soften a boot! As for the TLT7-P vs Carbonio the only difference seems to be the color. But if you want slightly softer, the TLT-7 Expedition appears to not have as stiff a cuff spine, though much of that could be cosmetic. Lou

  54. Don January 2nd, 2017 3:39 pm

    Commented earlier as well. Now on my third set of this model since late nov 2016 due to several issues. Firstly I broke the cable on the lower buckle where it passes hidden. I was tightening it up (not super tight, just usual tight for a downhill run) and the cable snapped clean. Took it back to distributor (MEC in Canada) and they replaced it. Then skied it for a couple weeks. During a hut trip ended up putting a crack in the carbon where the latch tang passes through the upper cuff of the buckle. The other one is showing signs of wear as well. I’m now on my third pair of boots. I love the boots, how they ski, the lightness, but loosing faith in the toughness of this model… third times the charm, right?

  55. Lou Dawson 2 January 2nd, 2017 3:53 pm

    Early adoption of probably the majority of modern ski touring produces has been fraught with this sort of thing. It used to really bother me, and I put a lot of energy into finding out why it happened. Now, after literally decades, I just sigh and advise people to be very careful of first-year products.

    We would report more on these sorts of things if we could, but we are constrained by a couple of things. When we use pre-production product we try to be fair about problems that appear to be easily correctable in retail manufacturing run. More, we sometimes don’t use product enough before retail to put the kind of abuse a real season of consumer use places on it. Tricky situation. Buying from a reputable shop that’s into helping with warranty issues is key.


  56. Ernie Bodie January 5th, 2017 11:25 am

    I now have 4 days in on my TLT7s. The technology, weight, and fit are optimal for me. I typically have issues with my super-sized ankles, but these boots accommodated them with minimal mods – and custom footbeds.

    The issue I have is with the stock liners, which are super-light. Somehow I managed to frostbite 4 toes with moderately cold temps around -10C. My first frostbite in 40 years of touring. So time for new warmer liners! Any recommendations for warmer liners that would work with this boot? I’m willing to give up some of the huge flex that walk mode provides.

  57. Lou Dawson 2 January 5th, 2017 11:45 am

    Ernie, any liner molded to your foot and to the inside of the shell is going to be pretty much the same wall thickness and warmth, and the heavier the liner, the denser the foam and perhaps even less warmth. I’ve worked on my TLT-6 quite a bit to make them warmer, main thing was punching out the toe box enough so I had more room for toe circulation, and less compression of the liner foam while fitting. I also use the boot gloves. Much of keeping feet warm is about boot fit, even how they fit in areas other than the toes that could choke off blood circulation.

    Now that you damaged your toes, you may need heated footbeds or socks for a season or two, no matter what boot or liner.


  58. Matti January 21st, 2017 7:47 am

    Have been now touring for 6 days with these including 1/2 day testing at resort. I like the fit of these and also performance. Toured in -20c without cold feet. Here are few issues I have noticed:
    – Liner cuff velcro closures ripped off already during my third day. Just emailed regarding this and new liners are on their way. Great customer service.
    – I have noticed that boot carbon fiber cuff makes some kind of friction during touring and that creates some carbon fiber dust. I’m a bit worried about that, if the cuff starts to wear. I also asked about that in my email to dynafit but didn’t get any reply.

  59. jbo January 22nd, 2017 10:56 pm

    @Matti – Are you touring with the yellow buckle closed? If not there will be some rubbing of the Titanex fiber (not carbon). Some folks cut off the liner Velcro fyi.

  60. Wintersmith January 23rd, 2017 5:06 am

    Anyone know if the TLT-7 problem with the Vipec Black also exists on the old Vipec “white” ?

  61. Lou Dawson 2 January 23rd, 2017 7:59 am

    Probably. Jbo?

  62. jbo January 23rd, 2017 9:46 am

    Hey Lou, yes same problem with the White version.

  63. Matti January 24th, 2017 1:28 am

    @jbo, yes I’m touring with yellow buckle closed. There is already very deep grooves in my both boots just below the Ultralock3.0 hole. The grooves are in that carbon coloured cuff. I can send photos of those to get the idea if that is possible?

  64. Wintersmith January 24th, 2017 2:00 am

    Vipec White update is much appreciated, thank you 🙂

  65. jbo January 24th, 2017 12:29 pm

    @Matti – A little dust wouldn’t be surprising, it happened sometimes with previous UltraLock models but would stop after a couple days. Deep grooves indicate a problem that needs investigating.

  66. Matti January 24th, 2017 8:35 pm

    Yes that what I was thinking also. I believe the main reason is that the edges of the ultralock3.0 metal piece attached with bolts are grinding the cuff during touring movement. For me it seems to do so when I have done some testing.

  67. Matti January 25th, 2017 8:49 am

    Here is link to my youtube about the wear… comments?

  68. Jason January 31st, 2017 12:04 pm


    I’m closing in on 50 years old, I’m a rock solid variable condition skier, and have just recently taken up ski touring, focusing on the Colorado Hut system and social time with friends backcountry in the Leadville, CO area. I have a really basic question about fit and performance with these boots… My foot LOVES the fit, if I’m in a size that is a bit long. Do you think that will have much if any impact on me in this new activity?

    In terms of general volume, 29 is the answer, but I would need the toe punched, and probably the outer mid foot as well, plus some liner work on the top of the instep. But the 30 absolutely fits like a glove out of the box, except that I’ve got 3/4 of an inch in front of my toes to the end of the liner. I really like these boots, all their mechanics seem great, and I love the weight. But I was just curious what all your experience says about that extra length in any realistic way performance-wise in this for a daily driver?

    Should I move on to a 29 backland carbon and hope it molds out well, or massage the heck out of the Scarpa Intuition liners in a shorter length F1 or Maestrale in order to get rid of that extra 3/4″ length in the boot? I’m 6′ and 220lbs with a Blizzard Zero G 95 and radical 2.0 binding waiting on my boot selection. Those other boots have a more ideal shell length when I tried them on, but a list of areas to adjust.

    The guys at the local shop thought I was nuts for wanting these boots. They thought burlier would be better for me. But I didn’t get the sense that they well understood my aspirations for simply a beautiful backcountry workout with some nice easy turns through trees in pow. Nothing radical. If that is where I go in a few years, I’d buy different boots if I needed them.

  69. Lou Dawson 2 February 1st, 2017 6:34 am

    Hi Jason, I’ll tackle this one…

    The “local shop” stocks something then thinks you’re nuts for wanting it? Interesting. They could be right, or not… Did anyone tell you that when you fit boots they’re not supposed to always feel perfect “out of the box?” Further, if you’ve never owned ski touring boots, how do you know they fit perfect?

    There is a well known process to fitting ski boots. It begins with the size of the shell (shell fit), then moves to heat molding with a correctly sized liner. Only after that process is partially completed will you know for sure if the shell and liner sizes are correct.

    Buying ski boots is not the same thing as taking ten minutes to try on a few pairs of running shoes at the shoe store, then picking one. It’s more involved and requires either lots of personal knowledge, or the services of a shop employee trained in ski boot fitting.

    In any case, the best fit for a ski touring boot does have some space in front of the toes. For comfort and warmth, and to prevent what can be long lasting damage to your toes from impacting the liner over and over again during the uphill, on skis or while snow climbing.

    As for actually changing the liner so you have less space in front of your toes, you can experiment with using the same shell but a shorter liner. Doing so might be beyond what your local shop wants to get involved in. But you could for example purchase some aftermarket liners and pay to have them molded, and see how that works.


  70. Jeff February 5th, 2017 9:53 pm

    @matti, the carbon dust has also been an issue for me since day 1 on the TLT7. I often get black spots on my hands after taking them off from the green ultralock, and the liners themselves have become quite blackened on the outer rear where they used to be light gray. I only have 10-12 days, but am concerned this could persist and might not just be limited to the break-in period. I haven’t noticed any groves, but will continue to monitor. The culprit is the metal insert rubbing on the inner carbon cuff. Besides this issue, I absolutely love the boots, so we’ll see how it goes from here.

  71. Jeff February 9th, 2017 10:10 am

    I should clarify it’s not “carbon”, but rather the titantex cuff (fiber layup pattern looks similar to carbon) that is responsible for the dust. I have the gray/silver TLT7 performance version.

  72. Craig February 19th, 2017 5:23 pm

    Great discussion.
    I’m a ski touring guide in BC. I’ve been skiing the tlt 5’s (too much fixed forward lean), and 6’s, (cold feet!) since they came out. I never used the removable tongues as I found it a hassle switching at transitions an for the most part didn’t need the stiffness in soft snow. I was intrigued by the prospect of warmer feet and fixed tongues of the 7’s so got a pair this fall.
    My first impression was they are light! And comfortable!. On the slopes once I got used to them they skied great and were warm! I found the lower buckle cable thing a bit awkward, especially with gloves on but got used to that too.
    But: They broke on day 8.
    Not any replaceable part, but the plastic. Basically the rear spoiler on one boot snapped off on the boot side of the pin rendering them into super articulating moccasins.
    Bubble burst I got back into my toe freezing tlt 6’s.
    Best boots I have skied for 8 days anyway. Waiting now for the replacements and hoping for better luck next time.

  73. ALW February 28th, 2017 1:52 am

    Got this boot for rando race training after comparing the weights of the PDG to TLT7P. In the size I need, 24-25 (ish) the weight difference worked out to a surprisingly small 110 grams.
    Wondering if anyone’s tried modding the fixed tongue on the TLT7P so that it’s removable to get to a closer weight to the PDG. The thinking behind it is to get a much better performing boot at a “somewhat” similar cost. I’m thinking the fixed tongue weighs about the 100 grams to bring it down to the 770 grams of the PDG. Have any weight weenies (like me) tried this mod yet??

  74. Mike March 4th, 2017 7:16 am

    So, I went to my local shop to check out these boots, and while I was there I mentioned how on your blog you said they are not compatible with the Vipecs. Almost immediately, they pretty much claimed you were “full of it” and just wanted to help Dynafit sell more bindings. I was right there at the shop where we pulled out the TLT7 and played around with the Vipec that was mounted to a demo board. None of us could demonstrate the supposed problems that you described.

    So I emailed Dynafit and Black Diamond. I haven’t heard back from Dynafit, but this was Black Diamond’s response:

    “Thanks for writing into us regarding the Vipec and TLT7 boot. I have gone to our retail location and personally tested the TLT7 and Vipec (both older white version and current black TUV). Both bindings were able to release and work with the TLT7 without issue. On the new Fritschi bindings that will be released next season (Tecton and Evo) these models will not be compatible with the TLT7.

    In short the Vipec Black TUV will work with the TLT7 without issue. Let me know if you have any further questions or concerns.”

    Lou…Care to comment? Any elaboration on your tests? Could you maybe post a video better explaining what makes them incompatible. I think plenty of us trust you, but it was weird that I couldn’t recreate the problem you described and neither could Black Diamond, enough that they just pretty much assured the compatibility of this setup…

    We’d love to know to what you seem to be the only one to know!

  75. Mike March 7th, 2017 2:46 pm

    And Dynafit’s response to my question asking about compatibility between Vipecs and TLT7s:

    “Thank you for reaching out! While we only guarantee our boots with our bindings, this type of incompatibility issue is not a known incompatibility issue that we are aware of. I would definitely recommend checking in with Diamir as well but I would expect that the TLT7 boot would work with the latest vipec.”

    So, Dynafit says there’s no problem, Black Diamond tested the setup personally and says there’s no problem, and I tested the setup with my shop guys and we couldn’t find the problem, but you are saying they won’t work.

    What’s the deal dude?

  76. Bob March 7th, 2017 10:50 pm

    Interesting. I contacted FFRITCHI directly and they said they did not work with the Vipec. A lot of confusion.

  77. Lou Dawson 2 March 8th, 2017 6:11 am

    UPDATE, see more information a few comments down from here.

    Bob and all, the confusion is because the mode of operation that doesn’t work is a kind of odd thing that most people don’t realize is part of the safety operation of the Vipec. That being that in a forward (upward) release, the boot not only comes out vertically at the heel, but the TOE OF THE BOOT HAS TO IMPACT THE BINDING TOE IN SUCH A WAY AS TO OPEN THE BINDING TOE TO COMPLETE THE RELEASE.
    1. Fritschi says TLT7 won’t do this correctly.
    2. I tested and verified.
    3. Ski shop says insulting things about me and then claims this isn’t so.

    Ok, whatever. Pretty funny a guy in a ski shop would try to make someone else wrong for selling things, and I laughed out loud at the concept that somehow this blog post is designed to sell more Dynafit stuff, when there are dozens of boot and binding options available on the market and we spend hundreds of hours and thousands of words covering much of it. I guess this person has little knowledge of the ski touring market these days… I’m happy to look at the boot-binding combo again and see if something changed, but can’t do that for a few days. Meanwhile, the test is easy:
    1. Place boot in Vipec without latching down the boot heel in ski mode, and without locking the toe touring lockout.
    2. Pivot the boot upward until the toe box of the boot impacts the binding.
    3. Doing this should open the binding mechanically (not by tearing the boot out), thus completing a forward-upward release.
    4. If the boot doesn’t come out as above, then it’s incompatible with the binding, or the binding is incompatible with the boot, or both…

    Again, if I’m wrong about this due to an inline change or something, fine. But the proof is in the physical testing, not what someone says who might not understand how the binding works, or, dare I say, wants to sell them (smile)?


  78. Lou Dawson 2 March 8th, 2017 6:22 am

    Mike, you’re taking what Dynafit wrote you as gospel truth? Read it again: “I would expect that the TLT7 boot would work with the latest vipec” That says nothing, it’s just conjecture. Actually pretty disappointing they couldn’t give a firm answer. But on the other hand, fair enough that they concentrate on their own bindings being compatible with their own boots. With little to no standardization in all this, that’s the best course of action for Dynafit.

  79. MarkW March 8th, 2017 8:55 am

    TLT7 & Vipec Black.

    For what it’s worth, I have 2 sets of VIpec Black bindings. One pair I got last season (early, from europe) and they came with 2 sets of toe blocks. The 2nd set of Vipec are from this season (USA) and they came with 3 sets of toe blocks.

    The TLT7’s clearly work with one of the sets of this year’s binding toe blocks. In DH mode (toe unlocked) the boot can swing up and open the binding. In climbing mode (toe locked) the binding does not open with forward swing. (Yes, you can twist and wrench the boot out, but that’s another matter, not the tested mode of operation)

    I’ve got 30 days on the boot/binding combo. I’m not happy with the durability/quality of the TLT7’s, but have no issues with the way they work with the Vipec Black bindings.

  80. See March 8th, 2017 8:59 am

    Re. the shape of the boot toe being critical to the proper functioning of the Vipec: I have some BD Prime boots that I’ve never really used because when I swing my boot to clear ice from the toe sockets, the boot hits the Dynafit ski/walk lever and releases the toe.

    Now it’s looking like some version of the Vipec may be the tech binding that finally offers release/retention function comparable to alpine bindings. I plan to try out some Vipecs soon on a freeride type setup. What does this have to do with Tlt7-Vipec compatibility? The boot in all the Fritschi Vipec videos, manuals, etc. is a Prime. I’m glad I held onto those boots.

    (And if the new “improved” Vipec doesn’t come with different toe blocks, I wonder what that means for compatibility.)

  81. See March 8th, 2017 9:01 am

    Note: I’m not sure the boot in the videos is a Prime, but it sure looks like it.

  82. Lou Dawson 2 March 8th, 2017 9:17 am

    If things have changed then I’m happy to revise this post, but honestly, I did test the TLT7 in Vipecs, as well as being informed by Fritschi that that toe shape was not compatible. Ongoing, I’ll check it out soonest. Lou

  83. Lou Dawson 2 March 9th, 2017 11:45 am

    Okay folks, while I didn’t appreciate being insulted as incentive to re-test, since this is my job I tested TLT 7 with Vipec BLACK and it does release out of toe unit during a vertical (upward) release, and it does release in the other modes insofar as my bench tests show. HOWEVER, YOU HAVE TO USE THE CORRECT SPACER CLIP ON THE TOE LEVER TO MATCH WITH A GIVEN SHAPE OF BOOT TOE BOX, AND, THERE MAY WELL BE COMBINATIONS OF BOOT AND BINDING THAT DO NOT WORK. Hence, testing is MANDATORY.

    The testing we did early this winter was extensive and we did find combinations of boot and binding that did not release. Please note that.

    Where TLT7 seems to not be reliable in terms of forward release of toe is with Vipec before the Black model, I tested one Vipec I have here that’s NOT the Black and the boot appeared to be incompatible. But perhaps they added a different size clip I don’t have, or perhaps some of this has to do with the size of the boot shell, since that would change the size of the toe box. So, again, it’s a simple test. Put the toe of the binding in downhill, put boot in binding toe, hinge boot forward, see if it pops out of the binding without a huge amount of force. If it comes out nicely, your boot is compatible. If not, do something about it.

    P.S., I’d add here that apparently there was some kind of inline change to the binding, as, honestly, I tested the heck out of it back when and there clearly was a problem with the boot coming out forward during an upward release. I’m super glad it now works, much less confusing. But bear in mind that this sort of thing should always be tested. You don’t want that ski flopping around still attached to your foot after a partial release.

    P.S., P.S., My test setup here does take quite a bit of force sometimes, seems to be dependent on exact angles or something, but in any case perhaps that’s why Fritschi says TLT7 is incompatible. Again, just bench test it and decide for yourself, AS YOU HAVE TO HAVE THE CORRECT SPACER CLIP ON THE TOE LEVER AND THINGS MAY STILL NOT WORK.

    I suppose my next step here is to see if Fritschi still officially says Vipec is still incompatible with TLT7. More soon.

    Thanks, Lou

  84. DG March 25th, 2017 6:52 am

    Hey guys, been following this for a while and about to pull the trigger on a set TLT7s as spring prices are down.

    My only concern is wear. Is there a final consensus since people are our there skiing them daily? Some of the posts seem to indicate there is excessive wear on the back of the boot near the lean/lock plate. Other issues? Any input would be great. Thanks-


  85. Galen April 13th, 2017 7:40 pm

    Hey just wanted to provide additional information on the boot from my experience the last two days, because I’m sure there’s plenty of bargain hunters like me out there. I’m coming from a 2011 dynafit zzero 4 C-TF 28.5. First, the tech and thoughtfulness of the boost is pretty amazing. Toe pins mounted further back does make an ergonomical difference and did Lou mention how lihjt they were? But I like being comfortable going up and down…the idea of just flipping one lever to make my foot comfortable for both is still not a reality.
    Too much space for my slim calves (which is something I struggle with). I didn’t want to distort the cuff by mounting the ratchet further back, so I dropped in an Eliminator from my resort boots and the boot became mind boggling stiff and responsive for a 1000grams.
    Tons of space for my forefoot, which after being in too small of a boot and developing left foot pain was very nice. But ultimately 28.5 may be too big. Heel is sliding around while hiking and not much padding back there!. I wear a US size 11-12…These boots fit better out of the box than maestrale-too much pressure on top of foot or scott cosmos 2(which also didn’t have extendable hooks on the cuff to use for walk mode…stupid, plus a lot of pics of broken walk mechanism).
    I’ve noticed the wear I read about where the metal latch for the ski/walk mechanism rubs on the back cuff…umm probably not a good sign. Hopefully get a smaller size boot/liner and reinforce that area. One last thing, trying to ski walk mode with ~70 degrees of cuff rotation is next to impossible haha!

    Just wanted to add my experience here too. I just tested both the Dynafit TLT6 Mountain CR and the TLT7 Expedition CR with the older, white Vipec 12 bindings. They both worked! I was able to easily get them to release when the binding was in ski mode and I rotated the boots all the way forward.

    Now I just need to decide which boot I like better. The TLT7 is definitely roomier for a wider foot, but it might even be too wide for me. Super comfortable though! The walk modes feel about the same, and the TLT7 might feel just a tiny bit stiffer, but it also feels shorter on my shins.

    But the good news is that they both worked properly with the white Vipecs 🙂

  87. Lou Dawson 2 May 13th, 2017 9:15 am

    Rob, indeed, due to the older Vipecs having the optional spacer “clips” that can be installed on the toe lever, most boots are fully compatible. This is true of the Vipec Black as well.

    Where it gets confusing is that I have verified here in my shop that a size 27.5 TLT7 is NOT compatible with Tecton or the Vipec Evo (assuming Evo uses same toe). The TLT7 will NOT correctly open the Vipec toe when forward-upward release occurs.

    Again, this is physically verified on my workbench.

    I am just about to buy a pair of these boots from Telemark Pyrenees but noticed that the boot was dark grey in colour, not silver like the version here and on the Dynafit website.

    Does anyone know if there are any differences between the boots, or is it some variation from one year to the next?

  89. Derek September 11th, 2017 11:12 pm

    I broke my shell on day 10 in of the TLT7 cr. Next day I broke the lower cable. Warranty without issue…..but….

    Has anyone had issues with the ski mode releasing! I’ve had several times when the lock released following a bad landing and backwards force. Not anything crazy, just off 1-2 meter drops.

    The lock plate has been replaced as it was damaged, but it’s happened again since.

    I have been very careful to make sure ski pants were not trappped in the lock buckle.

    Just broke my second pair of TLT7’s. The first pair, TLT7 Expedition had two failures: 1) plastic tongue cracked and 2) lower cable snapped (after about 25 days touring). Second pair, Dynafit upgraded to TLT7 Performance free of charge (through my local shop). Snapped the lower cable after about 8 days touring. Love the boots and the stiffness of the Performance but not sure about a third pair. When trying on boots at start of this season it was a coin toss between TLT7 and Scarpa F1.

  92. Alan April 11th, 2018 8:55 am

    Followup to my March 25, 2018 posting. Dynafit, with the advocacy of my local shop, fully refunded the purchase price on the Expeditions. I’ve switched to the Scarpa F1. The TLT7’s are still nice fitting and skiing boots but, perhaps, with a mechanical design flaw? While I experienced some inconvenience, in the end Dynafit’s response was great. I think my experience shows the benefits of working with a small, customer-focused local shop!

  93. Lou Dawson 2 April 11th, 2018 12:08 pm

    Hi Alan, thanks for the report. An engineer told me he thinks the problem with TLT-7 cable is that it’s anchored in a way that prevents rotation during use, and cables are much stronger and wear resistant when they’re allowed to rotate freely. Interesting. In any case, gear that breaks consistently is best avoided… after all, isn’t this 2018, not 1998 ? Lou

  94. Alan April 11th, 2018 12:09 pm

    Thanks Lou for your comments and couldn’t agree more with your final line! Sorry for the double post! Really like your site.

    Reminds me of the VW microbus we had when I was a kid that kept breaking clutch cables. Turns out one of the cable attachments was tweaked so the cable had a bend where it should have run straight. I have never seen a TLT7 in person, but it seems like it might be possible to modify so as to eliminate major kinks.

  96. Chris May 19th, 2018 3:02 pm

    I have had the boot buckle cable snap on three different boots (one was a warranty replacement), all snapped from where the cable enters the boot shell. Dynafit has dutifully replaced the boot each time, but I fear this will be a reoccurring issue…. I love these boots, so any suggestions for mods that might help alleviate this issue?

  97. Lou Dawson 2 May 19th, 2018 4:14 pm

    Hi Chris, what occurs to me is to remove the cable system and add a buckle… I’d grab a pair and experiment, but I need to move along to the future… Lou

  98. mike August 13th, 2018 9:50 am

    Hi Lou, just saw dynafit has posted its fall/winter line. I was wondering if you’ve heard anything about them fixing the issues with the TLT7?

  99. Greg December 22nd, 2018 6:55 pm

    Has anyone had problems with the cables freezing?
    I’ve had issues on multi day tours and on cold days (i.e. -20C/-4F). When the cable freezes in place it impossible to take the boot off because the cable can’t be removed from the black instep closure. Pulling on the cable eventually dislodges it but it’s super annoying.

  100. Alisse January 1st, 2019 9:13 pm

    Hey Greg, I was out yesterday in ~10* F and the cable on one TLT 7 boot froze — twice. First time couldn’t get the cable extended — had to warm the boot up to get it loose, and the second time it was stuck in the locked position so I couldn’t take the boot off until it thawed. Have you had any luck with WD40 or anything else?

  101. Will January 2nd, 2019 9:50 pm

    Another case of TLT7s breaking at the heel hinge. Cold day, log impact, but surprised to have damage to the boot and not the ski. No warranty, small discount from dynafit if I want a replacement. Love the boots otherwise, but not quite ready to buy them again

  102. Jake Krong January 25th, 2019 2:13 pm

    My wife and I both have these boots, and within two weeks of each other one of the steel cables on each pair of boots has snapped. Her pair probably had ~65 days of skiing on them and maybe ~80 days for mine. Dynafit is making the repairs, but it takes a while because according to them they basically have the take the entire upper of the boot apart to replace the cable. I’m a little worried about what this means for the non-broken boot in each set and the durability moving forward.

  103. Andreas January 26th, 2019 8:16 am

    For those having cable btrskage issues, I reccomend padding liners or getting a volume reducing footbed. Getting a snugger initial fit means not having to pull the cable so hard and overtensioning the cable. I have 100+ days in all kinds of temps and snow and haven’t had cable issues… yet

  104. jbo January 26th, 2019 11:19 am

    Andreas, yes. The TLT7 is a high volume boot and if you don’t fit it well you can see this problem. We’ve only seen the issue on folks who weren’t fitted for the boots.

  105. Ryan February 12th, 2019 12:07 am

    Following up on the frozen cable question.

    Has anyone come up with a good fix on this? Only had the issue on cold mornings during multi-day tours.

    Good lubricant?

  106. Alisse February 12th, 2019 8:54 am

    Hey Ryan, on really cold days, I’ve been spraying a shot of WD40 into the holes where the cables go into the shells. Haven’t had any issues again…
