Dynafit TLT5 Performance TF Ski Boot -
Climb easier, hike longer - a boot for elite skiers - Dynafit's TLT5 Performance TF ski boot trims weight with a carbon fiber cuff for lightness and stiff downhill support.


  • Double tongue system with driving booster increases stiffness for ripping it back down the hill

Traction and Grip:

  • Claw outsole provides better grip and traction, and Dynafit’s sole construction allows for re-soling in case of abrasion


  • Acti-flex zone allows 5mm of flexibility in the toe when climbing and skiing, and it does not affect torsional rigidity or downhill performance
  • Short rockered sole is crampon compatible for those tough rocky or icy summits
  • Carbon fiber cuff and lightweight TF liner combine for maximum downhill and uphill performance
  • Quick step inserts compatible to Dynafit bindings
  • Ultra-lock system opens up 60 degrees of mobility from walk to ski mode making skinning or running as easy as late fall training runs
Thanks to the super-light weight and smooth flex, the Dynafit TLT 5 Performance TF Alpine Touring Boot glides in the high altitude of the Himalayas and in the slightly lower altitude of your local rando races.

Dynafit TLT5 Performance TF Ski Boot Reviews:


These boots are pretty awesome. The combination of extremely low weight and huge range of motion put these boots in a class of their own.
I've heard of sizing up and using thicker liners to add warmth to the boots, but my experience has been good year-round in the cascades.
Notes after a year's usage:
-Fit was strange for my feet. the boot narrows as it goes down, especially at the arch. I had to use an insole to mitigate the pressure on the inside of my feet. Also pressure at the top of my foot at the lower buckle was minimized by loosening the buckle and with some effort by a pro bootfitter.
-The tongues are a little hard to keep track of sometimes since they don't fit nicely into pockets.
-the boots go on and off faster than tennis shoes
-I wear a size 10.5 street- and 11 running shoe and these were the correct length in a 29.0, BSL 317mm, although very narrow for my feet.

I haven't used these boots beyond trying them on and dialing them in on my bindings, but I am really excited to start touring on them this winter. Just pulling them out of the box was a jaw dropping experience as these boots are phenomenally light. I'm really pumped to see how well they drive my skis. They seem like they're going to be very capable climbing boots for those lines that require crampons. Great product, I think these boots are a winner.

Three years old, 250+ days toured, over 500,000 ft. of vert., heat molded to fit my fat American feet, and currently hanging tight in their fourth year of touring and skiing. The tongues are not as optional as they once were, though. Best boots!

light and fast

This is the most amazing two buckle boot on the market - light and powerful at the same time - hikes better than my boots. The only thing better is a ride to the top and who wants that...

Wow!! In comparison to other AT boots, these are the lightest. I usually fit a 98 mm last in my regular ski boots but these were even tighter on the side....almost like a 95 or 96 mm last.
