  Size Chart

The upagraded Speedfit Pro from Dynafit gets you up in the mountains without needing to leave a painfully large chunk of your wallet behind at the shop. With the same fit as the much revered TLT6 line, the boot is optimized for performance, ease of use, and reliability-- enough for many seasons of skiing. The Speedfit Pro offers similar skiing and walkability to the more expensive and carbon-heavy TLT8, in a bit heavier shell with a narrower last. The big upgrade in this version versus the Speedfit is a new cuff material, meant to stiffen up the downhill performance when the boot is cinched and buckled down. A burly, quick-release power strap alongside a simple and efficient two-buckle closure system make for fast transitions. With a standard toe lug housing the tech inserts, these boots come ready for automatic crampons, and the soft flex tongue makes for easy skinning on the way up while providing stout support on the way down. Built for on and off-piste touring alike, the TLT Speedfit Pro comes ready for whatever the season throws your way.

  • The Titantex fiber cuff is a titanium-infused glass that takes makes an affordable top-end boot that performs while climbing and descending.
  • The tried and true Ultra Lock System 2.0 gets you a quick and easy ski/walk lever system, so there's no fiddling with your boots at the top--just skiing.
  • A minor feature though it may be, the Ultra Lock Strap has glove-friendly, quick-release as well as a stitched 'speed bump' so you don't over-release your strap.
  • Non-removable Flex Tongues simplify life, and save you a world of trouble on windy days-- boot tongues have been known to be blown while unsecured for even the briefest of moments.

Questions & Reviews

Question from Dane
From the review and questions this would seem to be a straight trade for a TLT6 P. Is that correct? Then we get to the fixed tongue. Is the boot flex closer to a black tongue or a green tongue? Finally, is the liner the same Custom Light as what came in the black and orange boot? Thanks!
Answer from TSB
Hey Dane, I wouldn't so much say the Speedfit is a "straight trade" as it is a close cousin (apologies for the mixed metaphor). Lower shell/scaffo fit will be very similar between the Speedfit and the TLT6 Performance, though discerning Dyna-rippers will recall that the orange/black TLT6 P and the green/greenish TLT6 P were slightly different in fit (see question from Boris below). Consensus is that the upper cuff flex in the Speedfit is a touch softer than it was in either version, but in the same range as the green/orange (softer) tongues. The Custom Light liners are roughly the same thickness, but not exactly the same design, as the older foamies of the same name. Among other things, they're easier to heat mold and a bit warmer.
Answer from Kam
I think the fit is slightly roomier than my Mercury & Neo boots

Kam (used product a few times)
Just a quick preliminary review after a short uphilling-style tour and a day in the mountains. These boots are pretty sweet. They fit similar to my Dynafit Mercury & Neo boots before I had work done, with a touch more width in the forefoot (I will still need a punch). I love that there is no tongue to fiddle with. Stiffness is comparable to my Backland Carbon boots with the tongues in.

The one negative I have found is that the thin liner has a tendency to lead to shin bang against the cuff when driving a ski. I've carpet-tested the Backland liner, which has extra cushioning in the shin, and it feels like adding cushioning to the Speedfit liner could replicate the feel. Buckling the powerstrap (which is nice, but I wish it had some elasticity) underneath the boot cuff helps prevent some of the harsh feeling since you don't flex as hard against the cuff plastic.

It's a good boot and I look forward to testing it more once I get a few punches to make it fully comfy.
Reply from Kam
Update: It is a bit softer than the original Backland Carbon. I broke the boot cuff in a "just skiing along" situation. The walk mode lock popped out mid turn and, in doing so, cracked the cuff. I've had this situation occur in Mercury and Neo boots, which have a similar lock mechanism, without damage. It seems like a good boot but maybe fragile. Dynafit replaced the boots, so no issues there.

This was on day 3 of use.

Question from Boris
Is the fit similar to the wider black orange TLT6P, or more like the narrower green TLT6P ?
Answer from TSB
Boris, personal fitting of size 30 Mondo suggested a fit more akin the Halloween edition, but your results may vary, especially given liners differences between new and old "custom light" versions.

Question from Todd F
Are these going to be comparable to the TLT6 in performance? Looking to replace mine.
Answer from Jeff
Hey Todd! Yes, should be comparable to the TLT6 Performance. Without removable tongues.

Question from ryan
I am interested in replacing my TLT 6 mountain boots. Would this be a good fit? I am looking for a back country boot, fresh snow and spring couloir skiing.
Answer from Jeff
Ryan, If your TLT6 fit you perfectly, then yes this boot will be a good fit, it uses the same mold for the lower shell. It does have updated materials and a lighter weight. The tongue is not removable as in the 6 and stiffness is fairly comparable. If fit is not perfect, try our boot fitter.
