Dynafit TLT 6 P On-Snow Comparison – Green Vs Black

We covered the differences between the 2014-2015 Dynafit TLT6 (Green version), as well as the 2015-2016 (Black version) in this post. As with all our gear-nerding on Wildsnow, it’s in depth, and has a ton of good info. However, the workbench can only tell you so much. I decided buckle one of each model on my pedes and ski them for a day.

To summarize: The Black version has a lower shell (scaffo-shoe) that is made out of Pebax, while the older boot has a lower shell made out of Grilamid. The two plastics are very similar, however the new Pebax is perhaps slightly less stiff, and harder for a bootfitter to heat-punch. The new shell also has slightly more width in the forefoot, and a slightly higher instep, making it feel significantly more roomy. The new boot also has a cam-buckle power strap, rather than the traditional Velcro strap of the older, green boot. This test was performed with two “CL Custom Light” liners, which are the lighter version that we prefer. As pointed out here by reader Greg, the heavier CR liner can add some downhill performance and perhaps a snugger fit (depending on what insoles and other boot fitting tweaks you do.)

Mismatched boots. Old on the left, new on the right.

Mismatched boots. Old on the left, new on the right.

A few days ago I did a few laps in our local Colorado backcountry wearing the old green boot on my left foot, and the newer black boot on my right foot. For simplicity and comforts sake, I wore the same (new) liner in both boots, with my custom insoles. I did not heat-mold the liners. The boots were both size 27.5. The black boots were entirely stock, straight from the box. However, the older green boots have been moderately heat-punched at the forefoot, and the lower buckle has been replaced with one that rides on top of the shell instead of to the side — not something that would change downhill skiing performance. Although it was only a day of skiing, I encountered a variety of conditions, and it was a good test.

The first thing I noticed is that the 2015-2016 black boot feels great on my foot, straight out of the box, with no heat-molding. The 2014-2015 green boot felt comfortable as well, but even though it has been heat-punched significantly, it still felt lower volume than the new boot. I was surprised at how much of a difference I could feel, although the new shell is only a few millimeters wider (shows you how sensitive your feet are to small variations). This is excellent, as it means a more comfy, warmer boot, without boot-fitting chores common to the former TLT6 lasting.

Skinning in the boots, they feel quite similar. The new power strap is super easy to adjust with gloves, and can be cranked down much tighter than a traditional Velcro strap. However, the strap doesn’t loosen quite as much as the old Velcro strap (unless you completely undo it). This made the new boots have slightly less range of motion when skinning, when the power straps and buckles were loosened. However, to have comfort and control when skinning, I don’t loosen the Velcro strap entirely, which negates the difference. If you like your boots loosy-goosy when touring, you will notice a slight difference. If you remove the power strap, as many uphill-oriented TLT6 owners do, the difference is irrelevant.

On the transition, the new power strap design really shined. The Velcro power strap has always seemed like an afterthought on the TLT6 boots. Velcro straps are fussy, hard to use with gloves, get gummed up with ice, and drag in the snow when they are undone. Without the power strap, the TLT6 transition is faster than almost anything else. However, the fiddling with the Velcro almost negates the advantage. The newer power strap is significantly faster, can be easily operated with gloves, and gets super tight. Well done.

The 2015 TLT6 powerstrap loosened. Nice and trim. The grey bartack blocks the cam from coming all the way off the strap, unless it is pulled really had.

On the descent, the boots felt nearly identical. I did feel that the older, green boots are slightly stiffer. This would make sense, with the Grilamid vs. Pebax plastic. However, the difference was so subtle that I barely could tell, and it could have been more a factor of the difference of fit than the plastic.

In conclusion, with the exception of the fit, the differences between the two boots are quite subtle. Without wearing both on the same tour, I doubt I would be able to tell the difference between the two. In my opinion, if you already have a pair of TLT6 P boots, there’s no reason to upgrade. The improved fit can easily be achieved with heat-punching, rather than shelling out for a new pair. However, the wider fit will be wonderful for the majority of people purchasing new boots, as they will fit better out of the box, and be warmer. The new power strap is awesome, and makes changeovers quite a bit faster and less hassle. I wonder if Dynafit will be selling it individually? I’d put it on all three dozen pairs of boots in my quiver.

    NIce comparision, Louie, but I think you mean “slightly taller” instep, right? I think it’s worth noting that either boot will feel more powerful (but snugger) with the older and heavier CR liner.

  2. Andy Carey December 1st, 2015 9:06 am

    I’ve been removing the power straps from my Dynafit boots and carrying a booster strap in my pack in case I want to use it on the down; takes less than 30 sec to thread it thru the slats in the back of the TLT5, TLT6, & Mercury; I have it permanently mounted to my Zeus. For those interested, check out the website and see where the big differences comes.

  3. Lou Dawson 2 December 1st, 2015 9:07 am

    Thanks Greg for reading carefully. We made a few quick edits. Lou

  4. Nick December 1st, 2015 9:23 am

    Yeah, Andy’s on to the booster strap game. A touring partner of mine has been doing this for a few seasons now and I just bought a pair for my TLT6Ps. But no slats in back of 6Ps. Have to screw em down after removing the stock velcro version. Still, a world of a difference in transition ease and ski power vs the velcro. At least Dynafit is now including a similar product on their premier touring boot that costs about $35US aftermarket from Booster.

    Does Dynafit’s new strap have a progressive flex ala Boosters? A key feature of such a strap IMO

  5. swissiphic December 1st, 2015 9:26 am

    Don’t understand why the removal of powerstrap for merc/tlt 5/6 etc…. I find it invaluable for uphill scenarios involving steep sidehilling on hard surfaces or breakable crust. Snug it up slightly or firmly for edge kicking precision and grip…without the fiddly ski mode block mod thingy for the cuff buckle.

  6. Lou Dawson 2 December 1st, 2015 9:57 am

    Some things in life are best left a mystery. Lou

  7. XXX_er December 1st, 2015 10:11 am

    Agreed Lou, IME that would almost always be love

    but as for the merc powerstrap I couldn’t tell the difference so when I got my new vulcans I took the power strap off/ the shitty liners out, swapped them on/in the old mercs and sold that boot with new powerstraps & dynafit liner

  8. Andy Carey December 1st, 2015 10:35 am

    @swissiphic: I do use the surgical tubing attached with a loop of cord when I want more support of the lower leg without locking into the forward lean. One can always keep a booster strap on (permanently or intermittently). But I do a lot of ski touring that includes longish up hills and shortish drops to finally get to the steeper slopes I want to ski. Much of the time on the drops I don’t even lock in the heel or buckle the top buckle of the boot (use to be a telemark skier lol). In any case I found very little use for the power strap downhill compared to the booster strap. Fore the uphill you are talking about I would latch the upper strap with the lock blocker.

  9. Louie Dawson December 1st, 2015 10:50 am

    Good idea on the Booster strap in the pack, maybe I’ll have to try that. I have used Booster straps, and I’ve found that they tend to stick with ice, and are a bit tricky to operate with gloves. The Dynafit version seems smoother, and with the pull-cord it’s easy to operate with gloves. I might have to try to modify the original booster straps to use the pull-cord and bar-tacked stopper.

    The Dynafit version doesn’t have a stretch section, like the Booster straps do. Since the TLT6 boots aren’t super stiff (for me) to begin with, it still feels good when tightened down though.

  10. andrew December 1st, 2015 10:51 am

    nice comparo. however I would disagree that the increased volume/width in the new (black) model is “excellent.” its much easier to create than take away volume in the bootfitting process…

  11. swissiphic December 1st, 2015 11:35 am

    Just my opinion here in the myopic elitist world of ski touring 😉 but, any suggestions to remove the powerstrap (whatever form it may take; booster, velcro, duct tape…) is doing a disservice to potential neophyte users who may miss out on a much more pleasurable downhill ride with micro adjustabliity of fit, flex and function of boot using the strap…i.e., eliminate the ‘gaposis’ of gap in front of liner between upper plastic for chicken leggers’, place powerstrap on liner above plastic cuff for tweaking of forward flex feel and fit, uphilling powerstrap use; postholing, iceclimbing, steep couloir kick stepping and low grade rock climbing and finally coastal rain forest pure sufferage desperation climbing/kick stepping/falling emergency boot skiing on a crazy carpet of moss detached from rock slab where continuous adjustment of powerstrap for different pitches is required. 😉 Powerstrap offers a bit more finely tunable adjustability of fit and function than the ski/walk mod blocker cuff buckle thingy. Wow, didn’t actually mean to write an essay…the power of the morning coffee! 😉 I rest my case.

  12. Ben W December 1st, 2015 12:02 pm

    swissiphic, I would add that some boots seem to benefit more from power straps than others. On some boots almost serves as a extra buckle, while on others it is more of an accessory.

  13. GreggR December 1st, 2015 2:14 pm

    I have the green/black ones with carbon ($1000 two years ago) and they have always felt cramped although the same size as the previous 4 pairs of Dynafits. No room for a footbed with the stock liner. Since I don’t feel like buying another new pair of these boots, any suggestions as to an Intuition liner that would make these fit more like the new version? Any comments on tongue versus wrap liners in these boots?

  14. wyomingowen December 1st, 2015 4:09 pm

    I fixed a Titan strap to the tongue, goes in/out with each lap quite easily, tight as a booster strap without all the fiddling

  15. Matt Kinney December 1st, 2015 6:05 pm

    I put Booster Straps on my boots(albeit telemark) and the difference is very positive. They feel bomb-proof and stiffened everything better than the factory straps and my boots feel even better. There is an added fiddle factor at times, but not much. I think an end-loop on the strap would the ticket. I keep mine pre-set and they are still loose enough around my cuff for skinning. With an inch or so to grab, it has been pretty smooth at the transition. Not much adjusts with mittens regarding boots, but liner gloves solve that. Velcro was just becoming unreliable, slip, gets dirty, etc…

  16. Bill Balz December 1st, 2015 6:26 pm

    I ski an alpine rig with Lange RX 130 boot and zip fit stiff liners and use the stock Lange strap..all on current FIS slalom and 27 meter GS skis. I like it for ice-coast beer league level racing just fine. However, I feel as though I don’t need that stiffness in my TLT6 AT rig and have ditched the strap and mostly just use the yellow tongue now. Seems to me that the skis and bindings are more the limiting factor than the boots for control in sketchy situations. But I’m not shooting 50+ degree couloirs either here in the east. Would be interested in feedback from people on how hard they are skiing these AT rigs and whether this is more of a debate for unmarried guys under 30 years of age?

  17. Terry December 1st, 2015 6:34 pm

    Lou or Louie,
    Am wondering if you know if the sole dimensions have changed with the new models. More specifically, are there any differences in size between the TLT5, which I have now, and the newer TLT6s. Am wondering whether I’ll need to remount or adjust bindings if I buy new boots? I have Speed Superlights on a couple pairs of skis, which don’t allow adjustment.

  18. Lou 2 December 1st, 2015 8:32 pm

    Same length

  19. Wookie December 2nd, 2015 2:13 am

    Thanks for the comparison. Seeing as how several shops are offering the greens new at really low prices – might be a good time to get a steal! And I think I will miss the grilamid – it is just a dream to work with! As good as the new boot may be out of the box – nothing beats a custom fit, and that was really easy to get with the greens, even for hobbyists like me!

  20. Louie Dawson December 2nd, 2015 8:22 am

    Yep, it’ll also be great to have the option of essentially the same boot, in two different fits.

    At our shopping link above there’s the new TLT6 at full price, and the green version for %50 off. Looks like a pretty good deal!

  21. Eric Steig December 2nd, 2015 8:27 am

    My TLT5 power straps have an annoying habit of creeping up and off the boot at the front. Others have complained about this too? Is this not a problem on the TLT6?

  22. Greg Louie December 2nd, 2015 9:30 am

    Speaking of the superiority of the new Dynafit power straps, my MTN Labs were calling out for this treatment:

  23. swissiphic December 2nd, 2015 9:49 am

    Greg Louie; awesome d.i.y. got the smurf shoes, will try the mod. Although, i’m finding good success for opening the strap with simultaneously pushing on tab while doing a deep forward knee bend….pushes it open to the fully loose extent for tour mode.

  24. Greg Louie December 2nd, 2015 10:55 am

    Yeah, that works too – I just had an itchy drill finger and couldn’t stop myself.

  25. Kristian December 2nd, 2015 5:06 pm

    Slightly off topic maybe, but what is different about the tlt6 c-one boot ? Anyone know if it is stiffer or lighter, maybe more bootfitter friendly?

  26. Lou Dawson 2 December 2nd, 2015 5:45 pm

    That’s the “Competence Center” boot for 2015/16. It does have a Grilamid lower shell and is supposedly only sold at “Competence Centers” which is a wrinkle on Dynafit retailing I’ve never quite understood. It has a fiberglas cuff which is pretty much the same thing as a carbon cuff though probably a few grams heavier. They’re pretty much the same boot as any other TLT6, though the Grilamid lower shell is indeed more boot fitter friendly. From what I recall, they also use this boot as their boot for demo days loaner fleet. Lou

  27. Atfred December 2nd, 2015 7:24 pm

    Hi Louie,

    Do you think that the last width of the new tlt6 is now about the same as the dynafit mercury?

    Thanks

  28. Lou Dawson 2 December 3rd, 2015 9:50 am

    Hi Atfred, Louie asked me to glance at the Skialper magazine for a take on this. They say the Vulcan measurement (same last as Merc) is 103 mm for the 27.5, and the TLT6 is 99.5. Interpret that as you will in terms of comparison of one to the other… Lou

  29. David Brophy December 3rd, 2015 10:35 am

    Hey Lou, I’d love to hear your thoughts on how you think these boots compare to the Atomic Backland Carbon Light…

  30. Gavin February 19th, 2017 4:24 pm

    Has anyone tried modding the Solomon Mtn Lab straps on to TLT6s (specifically the older green TLT6)? Verdict? Thoughts? Thanks!
