Dynafit TLT 5 Flex Lockout Mod

Like some readers here, I’m not a huge fan of the forefoot hinge in the TLT 5 backcountry skiing boots. A couple of steel pop rivets solved the annoyance.

Take out the liner, make sure you’ve identified a location where the white lower shell, the black hinge cover, and the yellow extra tongue holder overlap. Drill through and insert a pop rivet. I put in two for redundancy and to share the load.

For me, the fix did two things:

1) Made the foot platform rigid. While downhill skiing the stock shell flex zone allows the ball of your foot to bob up and down as you pressure the boot cuff essentially changing your foot’s ramp angle constantly and allowing more “give” in the cuff flex. Now that the metatarsal flex is gone, my boot feels like a solid platform, without having to place a shim on the ski under the ball of my foot – no extra ski drilling, minimal extra weight, no problems w/ ski crampon interference. While skinning, I prefer the solid platform over the flexible one. The only place I miss the flex is skating the valley floors and snowmobile riding.

2) Stiffened the boot in ski mode. Since the lower shell doesn’t hinge, the boot collapses less under forward pressure, a very noticeable sensation skiing on firm snow. The TLT5P is already plenty stiff laterally (I drive a 125mm ski every day) it’s just got a little more of a front seat to support me (150lbs) and my huge work pack (airbag, plus snow observation and guiding gear).

Also, I’ve re-pressed the cuff rivets to reduce the slop that developed between the cuff and lowers, moved the instep buckle (like what Lou describes here on Wildsnow), put in an Intuition liner, pushed the shell for a bit more big toe room and added a Booster strap (the old one w/ the light plastic buckle, not the heavy metal ones available today). They ski like a “beef boot” and walk like nordic boots. Love them!

Modify Dynafit TLT 5 backcountry skiing boots.

You'll need a couple of 16d 'box' nails (the thin type of 16d, not a 'sinker'). Get a handful so you can experiment. The cheapest ski gear you ever bought.

Ski mountaineering boot mod for Dynafit TLT.

Cut the tip off nail, deburr, flatten one side of the tip, then file a taper near the end so it inserts in the space behind the yellow rivet on the boot toe. The fit must be tight, and the depth of the area you flatten should be measured somehow. I used the depth gauge on a caliper.

Ski mountaineering boots fitting and modification.

Finished product is bent so it snaps down into space, as shown, with upper end trapped below edge of yellow plastic. It took me about 10 tries to get it nearly perfect, about 10 minutes. It would be easier to make this T shaped so it still snapped down inside the yellow plastic, but required less fancy bending. I could do that with my welder, but I wanted to keep this as an ultra simple build of something fun. If you fit the lower end tight behind the yellow rivet, it locks out virtually all the flex. If the unit tends to pop up out of the boot, a hunk of duct tape will provide. But it seems quite solid.

    Awesome! I was wondering about this. Now I just need to guts to drill into my expensive-a$$ boots.

  2. Lou December 1st, 2011 9:58 am

    Andy, lots of people really like the small amount of flex. Even in my case, though I’m not a fan of the concept, I have to admit it does help my crippled left foot and leg (fused ankle) by giving the boot more movement in touring mode. I wouldn’t even mind it in alpine mode if it was a firmer flex, but I can really feel it bounce and don’t prefer that effect as it’s not “progressive” or damped. Thus, in alpine mode I like having a shim under the ball of my foot, and will probably experiment with the mod presented in this post.

    Mainly, I wish there was a way to switch the flex on and off. Now that would be incredibly cool. I can think of an easy way to implement that, but it would be cumbersome as a homebrew.

  3. Lou December 1st, 2011 10:13 am

    !!! I just devised an elegant and reversible way of locking out 99% of ball-of-foot flex in TLT 5. Going for a workout, when I return I’ll add to this blog post. Just two photographs will show it. Less than a cent worth of parts gets you the joy. Some of you thinkers out there can probably guess what it is.

  4. Nick December 1st, 2011 11:56 am

    I know Fedricio may chime in here to chasitize me, but man it is tough reading all these posts about mods to such an expensive boot. I love the concept of this boot, but will likely hold out for future models that can at least incorporate some of these great suggestions into new models. Not necessarily this particular one, but some of the after-market mods that have been popping up on WS (e.g., the tounge to permit the cable to remain in place while touring but without locking into ski mode). Also corrections to the forward lean (e.g., alternate options) sound like they may be in the works.

    Serious hats off to all you DIYers on WS about coming up with these mods (and I know Lou that you love this stuff :)) but sometimes I just want to be lazy, bake the liners and have a perfect boot!! Haha – is that too much to ask for?

  5. Lou December 1st, 2011 12:20 pm

    Federico has that same concern. I’ve told him to not worry, Americans mod their $50,000 trucks too, and no fewer are sold because of that. Besides, isn’t Dynafit working with a famous boot modder to design and produce another revolutionary boot for 2012/2013? Modders are just designers who don’t have a job with Dynafit — until they do.

  6. Lou December 1st, 2011 12:20 pm

    NEW MOD POSTED, see lower part of post above.

  7. Lou December 1st, 2011 12:23 pm

    Nick, P.S., since you’ve found the perfect boot, I’d advise you to stick with it. Otherwise, you might want to consider some mods of your own instead of suffering in silence (grin).

  8. Jonathan Shefftz December 1st, 2011 1:06 pm

    For rivet repressing, my DyNA had loosened up really badly, but then Dyanfit/Salewa repressed them this fall, and they are now super tight.
    But just curious, if my TLT5 start to loose up during the season, any suggestions for what kind of shop might have a rivet press with sufficiently large cups? (I called around, but could find anyone who did.)

  9. Tyler Beck December 1st, 2011 1:17 pm

    Nice work on the mod. Curious, are you going to put this in before each down and pull it out for the up? Also, do you carry your additional tongues for the ski down? It sure does feel like a lot to mess with…. 🙂


  10. Lou December 1st, 2011 1:56 pm

    Tyler, I’d plan on just leaving it in, probably with a bit of duct tape. Was trying to cook up something that didn’t require drilling the boot. I don’t carry the tongues, way too fiddly for my taste. If I want stiffer tongues, I’ll just rivet them into the boot. Have been thinking of doing so. Lou

  11. Phil M December 1st, 2011 2:23 pm

    It seems like if Dynafit wants to do this, they could mod the boot fairly easily so that an installed tongue locks out the flex. This would be ideal – no additional steps, and you get the flex only when you want it.

    I’m thinking about something as simple as a hard nub molded to the toe of the boot, around where the current flex-rivet is. The removable tongue would jam between that and the current tongue-retaining nub on the pseudo-tongue, locking out the flex. Or, at least making it extremely stiff and progressive. There would be a ton of force on it, but the lower buckle holds things together so well down there that it seems quite possible.

  12. Nick December 1st, 2011 3:04 pm

    Lou – alas, therein lies the rub – there is no perfect boot!

  13. Craig December 1st, 2011 3:09 pm


    If you wanted to improve that mod a bit and make it more permanent, you could make some sort of hinge which would lock down and plug the travel of that critical rivet. I’m thinking something similar to the lean lock on the TLT 5, where the buckle has a protrusion which fits into the hole in the rear of the boot. Same idea, except that protrusion would plug the rivet’s slot and lock out the flex. Less fiddly and easy to switch from locked to flex mode.

  14. Dimitri December 1st, 2011 3:43 pm

    i picked up a pair of these recently in Chamonix (literary, i didn’t buy them) and was amazed at their weight and construction. I currently ski a DB quadrant and I am more than satisfied at with their downhill performance. does anyone out there have the capacity to compare these boots in that respect?

    p.s. im not expecting an engineering thesis here, be real world please..

  15. Lou December 1st, 2011 4:31 pm

    Craig, I was originally thinking of something on a hinge, but that was too complex for my taste, since I’d be leaving the device in, not swapping it in and out during the day. I’ll leave the hinge improvement up to you guys!

  16. Lou December 1st, 2011 4:32 pm

    I’d also add that my method is not as solid as Ben’s. If you have no need for the flex and want to beef up the boot, just rivet it like Ben did.

  17. mike bromberg December 1st, 2011 5:31 pm

    nice one Ben! I’m definitely going for this. I suppose if one wanted to make this mod reversible they could use screw rivets?
    I tried intuitions in my TLT5p’s and hated the huge amount of forward lean.
    It’s a nice boot but I tend to pick the maestrale more often because I prefer the nice progressive flex as opposed to the abrupt/harsh feel of the TLT5p, I wish I had gone for the mountains.

  18. Lou December 1st, 2011 5:52 pm

    Mike, if you don’t like the harsh feel, why rivet the things? That’ll just make them even less forgiving. Good point about the screw rivets, but a bit hard to reach inside there to hold them for tightening. Lou

  19. Caleb December 1st, 2011 7:22 pm

    Mike, it looks like you mean the intuitions have something to do with the forward lean. I’m about to add some intuition alpines to my mountains. I would think with the extra amount of foam the intuition provides, you could mold them in a way that lessens the angle (as minimal as that may be)…………

  20. Lou December 1st, 2011 8:06 pm

    Caleb, some Intuitions tend to be fairly thick behind the calf, and since the angle of the boot shell is fixed at the rear, that can really jack you forward. I’ve had trouble with that myself.

  21. Greg Louie December 1st, 2011 8:42 pm

    I didn’t care for the abrupt “too stiff too soon” flex of the TLT5P either, and found that chopping off the tongues just below the power strap (about the top 1 7/8″) made them ski just about right. Easy flexing to start, but solid enough to resist totally caving in when pressure is applied.

  22. Lou December 1st, 2011 8:45 pm

    Greg, did you try not using the power strap?

  23. Lou December 1st, 2011 8:48 pm

    Important, with my mod: Only flatten one side of the nail and run the flat against the metal washer. The curved side of the nail needs to go against the yellow plastic, otherwise you risk damaging the plastic as the boot presses down against the nail.

  24. Greg Louie December 2nd, 2011 9:48 am

    Yes, I tried a number of different combinations – with and without power strap, with and without tongue before I cut – but I’m satisfied with the result. I leave the reduced height tongue in all the time (except for our one rando race a year) and just open or close the buckle to transition . . .

  25. Federico December 2nd, 2011 12:03 pm

    Nick, surely you, Lou and all modders of the nice TLT5 will be punished one day 😉 … I’m kidding of course.

    I had a nice mail discussion with Lou a few days ago about the topic and I agree with him, especially with the fact that if a lot of people like to spend so much time discussing and tuning something is because they are very interested in it. Plus I also think in general a lot of people nowdays, thanks to internet, really likes a lot to discuss and try to share their experiences with others.

    What i personally don’t like is when I read negative comments especially about one of the most innovative and functional boots of the last … many … years.
    I might understand that somebody doesn’t like the flex area but much more do and it’s definitely one of the success point on the design of this boot.

    I also would like to remind that the TLT5 devlopement never had in mind to be a resort ski boot, and alpine boot, a freeride boot or anything like that. we wanted the best mountainering ski boots for top level ski mountaineers, professionals, guides… looking for the LIGHTEST boot with the best climbing agility … then it came out also stiff and very good for skiing 😉

    When we would like to have a boot MUCH better for skiing but heavier than 1kg with a wider fit, more insulation, and still amazingly good climbing abilities… we will be able to do it.. but it will not be a TLT5.

  26. Ali E December 2nd, 2011 12:22 pm


    My only problem with the TLT5 is the price. I live in NE Scotland, where there are a number of shops selling touring gear, including Dynafit, but none will stock the TLT5, because they think their customers will find it too expensive. I am sure this is the same in many other places.

    I understand that when the TLT5 was developed, you were aiming for a niche – and therefore limited – market of top level ski mountaineers, guides etc, but what you ended up with was a runaway success with a much broader customer base of good, recreational ski mountaineers. I just get the feeling that the TLT5 would be the boot of choice for many more people if it were priced more competitively.

    As it is, I cannot even try them on, because no will stock them.

  27. Lou December 2nd, 2011 12:24 pm

    Federico makes a VERY good point, one which I echo. We Norte-Americanos need to be careful not to try and make a touring boot into a resort boot. I don’t know if anyone noticed, but nearly all my own mods up to the flex lockout were strictly for fit and comfort, ditto for nearly every other mod we’ve had here. And even the flex lockout could be argued to be as much for touring as for the downhill, as not every person feels the need for their boot to sag while up on their heel elevators.

    As for product criticism, we welcome it so long as it’s constructive and comes from experience, as we are firm believers that nothing is perfect and everything can be improved.

    I think the most valid crit of the TLT5 boots is that in some cases, some sort of adjustable cuff angle would be very nice to have. I’ve gotten tons of feedback on that, both in public and private, so I know that’s an accurate take.

    But the reason that take is out there is because people are buying and using the boot!


  28. Lou December 2nd, 2011 12:30 pm

    RE price: We the touring public want lighter weight boots that perform. Making boots like that is expensive. We need to get used to it, or just buy a used boot from the Ebay or the local consignment store and accept that we’ll haul around a pound more on each foot. Really, if Dynafit wants to make a revolutionary and incredibly costly to manufacture boot, and charge for it, where is the wrong in that?

    My only gripe in the area of cost is that I do know people who spent good money on these boots, and they’re getting some wear in areas such as the cuff pivot that could be prevented by a small design change such as some sort of bushing system, preferably owner serviceable.

    It’s like an expensive carbon bicycle. You spend the money, but when the tires wear out from riding your fun machine, you expect to be able to swap another pair of them on with minimal fuss.

  29. Lou December 2nd, 2011 12:31 pm

    As for punishment, every time I use a heavier boot I get punished. Is not that enough, Fede? (grin)

  30. Ali E December 2nd, 2011 1:37 pm

    Lou, of course you’re right, a revolutionary product like the TLT5 is expensive to develop. I was musing more on whether Dynafit had perhaps misjudged the popularity of these boots and if so, whether a slightly cheaper price point might not drive even more phenomenal sales. Then again, maybe it’s just the tightfisted Scot in me 🙂 At the moment it’s a choice between these babies or a week’s touring in the Alps. Maybe Santa will be kind to me.

  31. Federico December 2nd, 2011 1:52 pm

    Ali … I’m very sorry for the price but Lou already described perfectly the reason why it’s expensive…
    And by the way despite from your thought the TLT5 line is not a niche product … at the moment it’s our best selling and most probably the best selling touring line in the world now… talking abut numbers not by internet posts… on internet posts for sure TLT5 is first with no peer 😉

    The TLT5 Mountain is a very affordable boot, sold in europe between 430 to 480 euros which is the nowdays standard for a top end boot. and it’s an enough good ski boot for most of the skiers.

    The performance is obviously more expensive… consider that only the carbon cuff pair costs nearly as a full TLT5 mountain boot …

    As lou said top products have a top price…not because of gaining more money but because of the higher production costs and the higher R&D costs.

  32. Lou December 2nd, 2011 2:16 pm

    Take my word for it as well, they sell bunches and bunches of TLT5 boots. There is some argument about what’s more popular overall, the Scarpa Maestrale or TLT5. It’s a battle!

  33. Ali E December 2nd, 2011 2:38 pm

    Federico, Lou, good to hear they are selling so well. Need to start saving the pennies…

  34. stephen December 2nd, 2011 9:22 pm

    Am seriously considering getting one of the TLT5 boots for next (southern) winter. I know some people have been rather negative about the Mountain, but have been wondering if this is because 1) the skiers are heavy, 2) there’s more bragging rights with the P, 3) the P “must be better because it costs more.” (The two people I’ve met with the Mountain were both happy with them.)

    Since I’m 65kg max, and come from tele and XC skiing rather than alpine I’m wondering if I might notice any difference, and if the softer flex of the Mountain cuff might not actually suit me better.

    FWIW, at present I have Scarpa F3s, and have swapped to softer tongues since the forward flex was too stiff for my liking; I’ve found these to be plenty stiff enough laterally for the skiing I do. The TLT5 actually fits me better due to the different shell break and close fitting last, plus there’s less weight and greater freedom of movement, so everything seems good.

    Would I really be penalising myself by getting the Mountain TF rather than the Performance TF???

  35. Lou December 3rd, 2011 5:14 am

    Stephen, some people are negative about anything… lots of folks love TLT5 Mountain. I think you’d be very happy with it. Lou

  36. mike bromberg December 3rd, 2011 10:31 am

    I always had just a mild distaste for the metatarsal flex especially on firm terrain as well as when cramponing. I ran into Ben the other night in town and he felt that with this mod he would find no other comparable boot.
    The TLT5 has certainly changed the game as far as touring boots go. I do end up skiing these often and they are bone stock.
    For me, this is an excellent ski mountaineering boot, especially when the climbing challenges exceed the skiing difficulties.

  37. Greg Louie December 3rd, 2011 10:53 am

    @stephen – If you felt the forward flex of the F3 was too much in the stock boot, the TLT 5M will be more than adequate (you may even end up skiing it without tongues).

  38. nick vitale December 3rd, 2011 12:00 pm

    I was wondering if anyone has been skiing the dynafit TLT 5 mountian without the power strap?
    they seem to get in the way hiking but I’ve only made a few turns without them as we don’t have much snow yet.

  39. Lou December 4th, 2011 9:08 pm

    I generally ditch the power strap with all my boots. Sometimes that’s a mistake, but usually it’s just so much less fiddly. I’ve been using it with my TLT5s, but once I get the tongue I like figured out, I’ll probably ditch it on those as well.

  40. stephen December 4th, 2011 9:45 pm

    ^ Thanks Lou and (Greg) Louie!

    Seems like most of the comments I’ve seen online about the Mountain have been to the effect that the Performance is much better, but not sure how many of these were based on ego versus testing. 🙂

  41. Lou December 4th, 2011 9:48 pm

    “Much” is the wrong word. I’ve skied both. But you do notice a difference. For some folks, the carbon cuff is too stiff….

  42. Ali E December 5th, 2011 10:39 am

    Lou (and anyone else who cares to comment)

    Well. Santa heard me and I have been promised a pair of TLT5s for Christmas! Now I just need to decide between the Performance and Mountain models. I weigh 70 kg (155 lbs) and ski the original Manaslus in 177. I am not an overly aggressive skier. My boots for the last 5 years have been the Scarpa Spirit 3, so they are really my only benchmark. My question is: How stiff is the Mountain (with and without tongue) compared to the Spirit 3 and same for the Performance (with and without tongue)? If price were not an issue, is there any reason I should prefer the Mountain over the Performance? Lou, when you say the Performance can be too stiff for some people, could you expand on that? I don’t want to make any mistakes with something so expensive! Many thanks, Ali

  43. Lou December 5th, 2011 10:46 am

    At 155, not agro, happy with Spirit 3, you’ll be fine in the TLT5 Mountain. The difference between the two boots is minimal. “How stiff… compared,” is a tough one to be super specific about without scientific testing. Personally, the only big reason I like the Performance better is it’s slightly lighter. Weight is everything (grin). I’m wondering if the cuff rivets actually wear out slower on the Mountain model, which would be an advantage to consider. Lou

  44. Federico December 5th, 2011 12:09 pm

    Hi Lou, the weight between the performance and mountain is not an issue. with the same liner the difference is countable in 10-15 grams… which would never justify the retail price difference. While the stiffness difference is quite noticable. We rated it on the flex testing machine around 35% more on the performance, which is a lot.
    Very strange you don’t feel the difference. Most of other skiers, testers feel it and a lot.

    I obviously refers to standard products in standard configuration out of the box … modification of the standard, including liner change, shell boilng/molding etc… are perfect to customize products but have pretty noticeable results as well on product performances.

    So Ali … if you want my opinion … if money are not an issue goes with the Performance but if they are an issue, and compared with your previouse boots you will surely be fine enough with the Mountain.

    The other big blus of the performance is that you can ski it perfectly without the tongues… the mountain without tongues would be probably a bit too less if used in combination with a pair of Manaslu.

    But at the end it’s all about ski technique and own expectation 😉

  45. Ali E December 5th, 2011 12:48 pm

    Thanks Lou and Fede both. I have to say, I am leaning towards the Performance. Now another dilemma: I am somewhere between a Mondo 29 and 29.5. My left foot is bigger than my right and the 29 just touches the tip of my left toe when I am standing weighted, the 29.5 has a bit of spare. I know they are the same shell size, so is there any advantage in a longer or shorter liner? My Spirit 3s were always a bit too small on the left foot, meaning I got black toes every year; not something I want to have with these new (very expensive!) boots! Also, I think I might appreciate the extra space when hiking downhill or kicking steps on climbs. But if I go for the 29.5, will they pack out and end up slopping?

  46. Jonathan Shefftz December 5th, 2011 1:39 pm

    Fede, the problem with dismissing the weight differential as solely attributable to the liner is that your North American distributor carries only the TF-X version of the Mountain.
    Back to the Performance version, the only changes I would make are:
    1. The boot currently has too much forward lean for me, and I suspect also too much for the majority of skiers (even if they don’t realize it, as skiers often mistake excessive knee flexion for a well-balanced stance).
    2. Also, the stock velcro strap is fine for what it is, I’ve been experimenting this season so far with a Scarpa Active Power Strap, which essentially provides the performance of a heavy clunky Booster Strap but with no noticeable weight penalty.

  47. Plinko December 5th, 2011 1:44 pm


    Just spoke to Andrew (McLean) and he confirmed that Black Diamond has discontinued the 3/4 basket that he helped design.

    Amazing how something so little can make such a big difference in the security of pole placements, especially on the uptrack when conditions are firm. Brilliant design and a shame BD has lost touch.

    Think they’d reconsider if enough people expressed interest (ie public shaming on some of the forums)?

    [/ horde mode ON]

  48. Lou December 5th, 2011 1:51 pm

    LOL, public shaming? I don’t think that’s really our style here, but shame on here in the comments if your’e so inclined. Beyond that, seems like the perfect thing for the aftermarket to take care of. Or, just cut one side off a basket and be done with it.

    I do like those baskets.

  49. Lou December 5th, 2011 1:54 pm

    Jonathan, one interesting thing is that the Radical series bindings have slightly less ramp than the Vertical series. When I stick a TLT5 in one or the other, I notice the difference. Could be when they designed TLT5 cuff angle it was optimized for the Radical bindings. That said, even then it would still be too much for my preference, but perhaps okay for most people?

  50. Federico December 6th, 2011 1:20 am

    Jonathan and Lou … I know Lou is already using an intuition liner on his TLT5, what about you Jonathan? the TLT5 has been designed to work with a much thinner liner than “old” kind of liners… if you use a liner with much padded cuff like the intuition series you end up in chaning several degrees the forward lean angle. In that case I agree it become too much for a lot of people especially if they have skinny legs (like Lou for example)..
    Forward lean angle of boots depends strongly on how “thin” your calf is, thicker calf less angle, skinny calf more angle.
    So.. for Lou, the combination of skinny calf + intuition liner makes definitely too forward.
    In general a strong comment is that the TLT5 is too less forward… but depends a lot on the skiing style and what you used before.

    The “famouse” modification tool which will be be soon available will offer 2 diferent forward positions compared with the actual boots which will be -1° and +2° … so in a few words a little bit less and a little bit more.

  51. Lou December 6th, 2011 5:16 am

    Federico, you forgot, I actually use Intuition that is molded to virtually same thickness behind calf as stock liner. 13 mm. See http://www.wildsnow.com/4461/dynafit-tlt-5-performance-review/

    But YES, it is true that unless a person is careful about this, an aftermarket liner can radically change lean angle of lower leg (cuff lean).

    Using the aftermarket liner was mandatory for me, the stock one simply did not take up enough volume. I have very skinny/bony feet.

    More, I really like a liner that laces up around my foot, as the Intuition Pro Tour does. Without lacing, my heel moves up and down excessively in nearly any boot I’ve ever fitted, though moving the lower buckle aft helps immensely with that problem.


  52. Jonathan Shefftz December 6th, 2011 5:37 am

    Federico, rest assured that I would never use any liner other than the original TF liners in my DyNA and TLT5 — they are so absolutely perfect! I am so impressed at how the thickness and weight of the TF liner was significantly reduced, yet it still holds my put in place very well, and comfortably too. For skiing that puts my foot close to the shell (as it should be), and for off-snow scrambling I am able to have a 287mm boot sole for a 265mm foot, thereby enhancing agility.
    But I do have very skinny calves!

  53. Lou December 6th, 2011 5:44 am

    Believe me, I’d use the stock liner if I could. The one in the ZZeros works great for me, for example. But really, bottom line is you pick a boot as cool as the TLT5 and make it work through boot fitting techniques if necessary. Skiers have been doing that for what, a hundred years?

    The stock TX-F liners in the Mountain work great for me, partly because they do lace up, thus preventing the heel movement in tour mode that Lou mentions.

    And I had an extra $250 to put towards Dynafit bindings 🙂

    Wow this topic exploded. May I add to the insanity?
    I was able to pick up a pair of TLT 5 Performance this summer to use for some Rando races and touring here in the Wasatch and so far they rock! I was hoping that I could use the TLT5 as my daily driver paired up with something like a Vector or Manaslu, but I able to pick up a pair of 185 BD Carbon Justice super cheap and I think it might just be too much ski. I have a pair of Quadrants that I love but was hoping I could downgrade to just one boot all year…

    Lou, would you guess the TLT and Justice pairing to be insufficient? 6′ 180 lbs – average skier.

  56. Lou December 6th, 2011 2:25 pm

    Tyler, depends on your style. If you push it, you might want a bigger boot with more progressive flex, no ball-of-foot flex, etc.

    Well my TLT5 Performance boots arrived today! I’m not allowed to use them until Christmas, but I am going to get the TF liner baked at a local shop.

    The instructions that come with the boots say Dynafit recommend a blower tower rather than a convection oven. The shop that has agreed to do this only has the oven. Will this be OK? Also, how long should they be heated in the oven? A bootfitter I spoke to on the ‘phone mentioned 8 minutes, as they are thinner than your average thermo liner. Any authoritative answers greatly appreciated! Thanks.

    For my nearly identical TF liners, I had my DyNA done in a blower tower (thank you local REI — free too!) and then got the courage to do my TLT5 at home in my Scarpa boot oven. But like that bootfitter said, I went short on the time — about 8 minutes (as opposed to the more typical 12-15 I use). Both came out fine.

  59. Ali E December 15th, 2011 2:36 pm

    That’s great, thanks Jonathan. Do you use the supplied footbeds in the TLT5s? I have been ski touring and running with custom Superfeet footbeds (dark green), although I also have a pair of Conformable custom footbeds that I used to use in my downhill boots (long since gone!). What would be best in the TLT5s: The stock inserts, Superfeet or Conformable?

  60. Jonathan Shefftz December 15th, 2011 2:41 pm

    It all depends on how much support and customization you need.
    The stock footbeds are pretty minimal. Although then again, they are light!
    I have Superfeet in some of my bike shoes & xc ski boots. Definitely a step up in terms of support.
    For my AT boots though, I always use custom footbeds. Pricey (and adds a wee bit of weight), but they keep my feet from pronating (which also helps to keep my 265mm foot length short inside the 287mm TLT5/DyNA bsl), plus they’re comfier.

    I have a pair of TLT5 performance boots and am a bit concerned, as you have noted, about the durability of the hinge. After two days of use, I noticed some black powder on the shell below the hinge indicating wear of the carbon fiber cuff. I am thinking about actually lubricating the hinge to prevent wear on this “moving” part. Any thoughts? Amazing boots. Hope they last because I want to use them lots.

  62. Durango Joe February 5th, 2012 1:03 pm

    I’m wondering of other folks besides Lou and Ben have riveted or otherwise removed the metatarsal flex from their TLT 5p’s. What was your experience with it? Did you notice a big difference?

    Thanks for posting this fix! Intriguing. I love my TLT5p but wouldn’t mind a bit more downhill chops in tough snow conditions. But I’d just like to know a bit more before drilling holes in my boots or tweaking nails. Thanks!

  63. Chris September 24th, 2012 5:58 am

    does anyone know if there are other compatible lower buckle cables for TLT5s?

    i have a huge instep and while boot fit is ok, it could be better and more comfortable.

    the boot manual mentions longer cables for the lower buckle, but dynafit here in switzerland says they no longer make them.

    has anyone tried anything to get more lenght on the lower buckle?

  64. Plinko September 24th, 2012 12:39 pm

    No longer make them?? Strange. The TLT5P continues to be a current model this winter as well, (2012-2013) so they should stock parts for them. Last winter I had different sized/length lower cables sent to me from Dynafit North America with very little hassle. If you are unable to find a replacement, (or happen to break or lose one in the field) you can simply use a loop of 3mm accessory cord

  65. Lou Dawson September 24th, 2012 12:44 pm

    Or do a buckle remount if you just need a bit of extra…

  66. Jack September 24th, 2012 12:52 pm

    Just bought a pair of TLT5 Mountains. Wow! I haven’t skiied them yet, but they are unbelievably light. If you google “Dynafit TLT5 Mountain” you’ll find that Fire on the Mountain in NH has them at well below street price.
    They feel more like ballet slippers than anything else. Thanks, Lou et al. for supporting this novice. I’m so happy that the European last wasn’t a fit problem.

  67. Chris September 24th, 2012 1:47 pm

    Guys – thanks for the help!

    @plinko: I had someone from Salewa/dynafit contact me just now and they are not aware of any replacement cable… I am waiting for Dynafit in Switzerland to come back to me, but they seemed puzzled too. Was hoping to get a factory part, but i guess i might have to do the accessory cord thing in the end…

    @Lou: you build wood cabins, but I struggle with a light bulb! Relocating buckles for me is a virtually foolproof way of getting myself somewhere where the only way out is new boots!

  68. Lou Dawson September 24th, 2012 2:03 pm

    Chris, understood. Boot fitters are good at that stuff. Lou

    I ski the TLT Carbon and the BD Quadrant. I love’m both.
    my background: have owned and destroyed Garmont Adrenalines, BD Methods. I demoed quite a few touring boots working at a shop winter 10/11, including Maestrales. And i’m big: 6’2″, 220 lbs+. I’m not a racer background, but i am aggressive, powerful, and backcountry oriented.
    The Quadrant skiis pretty well. It hikes amazing as 4 buckle overlaps go. I’ve skied a number of big skiis; i own Bluehouse Maestro 189s with tech binders.
    I like to ski the TLT Performance/Carbon WITH the tongues on the downs on 187 BD Aspects (90mm waist) with FT12 binders.
    I like to use the right tool for the job, but doesn’t always happen. The TLTs are weak when noodling in the backseat, like when running the Aspects (90mm waist) in super deep Rocky blower or Sierra spring-ment. I also don’t care for the metatarsal flex (which i will mod out). Though TLTs ski strong in blower. And are definitely stiffer than Maestrales. TLTs ski great until they blow through the flex (happens 10% tops), which generally happens when bottoming a turn in deep conditions. I feel (and ski) confident at speed on TLTs.
    I feel the Quadrant has a more linear flex than i would like. Or they could just be stiffer. However, I am much more confident in Quadrants when maching into chop, crud, debris, bumps, etc. There is enough boot to regain control compared to TLTs, like when running into tracks from freshies above.
    The weight difference is very noticeable on the ups, though the Quadrant is great for skinning/booting in snow (as in, not booting up rocks and talus).
    Overall tactile feel is the biggest difference i think. There is much less plastic on the TLT. My favorite part about TLTs is the tactile feel (and weight) when, say, edging some 5.7 or kick-gliding and skating across flats. And they ski great!
    Feel free to ask more specific questions if you like; i’ll try to be as specific as possible.

    salewa makes a mountaineering boot that allows you to lock out the metatarsal flex by turning a little key in the sole. maybe dynafit will add something like this to future boots. the flex is nice if you have some trail pounding to do before reaching snow.

  71. Bob April 27th, 2014 1:17 pm

    Where is the best place to locate the rivets when locking out a TLT5? Based on the location of the rivets in the photo above it looks like one might not go through the lower shell. The lower shell seems to have a tab that extends into the boot for the original rivet to pass through to allow the boot to flex. Would it be better to locate the rivets in the black plastic to make sure they got through the lower shell material and to spread the forces out? A photo of the “best potential” locations would be great.

  72. Lou Dawson April 28th, 2014 7:13 am

    Bob, the best way to determine the location is just feel inside the boot with your finger and figure out a place where the rivets will indeed go through all the layers. Even with a photo, you’d still need to do that as the areas with three layers are limited in area. I didn’t find it very tough to figure out. In terms of whether to include the yellow plastic or not, I just thought it better to catch all layers but it would probably work just to rivet through the black. You could always go back and add a third rivet if necessary. Lou

  73. Greg Tolman January 27th, 2015 10:59 am

    Does locking out the metatarsal flex make these boots compatible with any non-tech bindings?

  74. Lou Dawson 2 January 27th, 2015 12:09 pm

    No, they don’t have a DIN/ISO shaped sole. Lou
