Dynafit One PX-TF Ski Boot -
It may not be the Chosen One, nor the One Ring and it’s definitely not the Keanu-Reaves-One, but Dynafit’s One PX-TF women’s ski boot may just be the one-and-only that you’ve been looking for. Winner of the 2013 Powder Skier’s Choice and Backcountry Gear Guide Select awards, the women’s specific One PX-TF combines lightweight skinning performance with a boot cut for women that is stiff enough that it won’t feel lost and out of place at the resort.
The One’s three buckles include both an instep buckle that will hold you foot down without compressing your arch and Dynafit’s Ultra-Lock buckle that tightens the upper cuff and puts you in ski mode with the same motion – smoothing out transitions and preventing those first three powder turns in walk mode. While skinning, the One allows for a full 60 degrees of range and the wider last increases warmth and comfort. The Dynafit One PX-TF women’s ski boot comes with Tech inserts and a grippy Dynafit Pro Sole, compatible with all touring bindings. The One comes with Dynafit’s lace-up heat moldable TF Universal Liner for individualized fit and comfort.


  • Lightweight thermo-formable (TF) liner with women-specific fit, for superior warmth, energy transfer, and performance


  • Pebax cuff and driving spoiler adds stiffness to the shell, holds heel down, and features an adjustable lean angle


  • VELCRO® Brand Fastener power strap


  • 103 mm last
  • Dynafit Pro short and rockered sole
  • Compatible with Dynafit Quick Step-In or standard touring binding
  • 3 buckles
  • Flex tongue for smooth pressure application that doesn't restrict the 60° cuff rotation.
  • Ski/walk mode with 60˚ cuff rotation is activated by top Ultra-Lock buckle.
  • Dynafit Pro, a durable, sticky rubber sole for sure, secure footing
  • 15-18 degrees of forward lean and 60-degree cuff rotation in walk mode, to accommodate your every move
  • Ultra lock system with a magnesium cuff buckle that lets you open and close the buckle easily and change between walk and ski mode
  • Pebax shell, a high-performance, thermoplastic elastomer for flexible impact-resistance and strength
  • Magnesium Ultra-Lock System for quick, easy release connected to walk mode
  • Thermoformable liner

This boot features several attributes of the TLT5, adapted to a wide range of customers. Compared to the TLT6, the ONE PX is a bit wider, warmer, stiffer (in ski mode) and more adjustable thanks to 3 buckles. The ONE PX is the perfect choice for ski tourers looking for the lightest and best performing ski boot in this category. Notable features include: a cuff with the widest and smoothest cuff ro- tation possible on the ski touring category; a new articulated cuff buckle ULTRA LOCK SYSTEM 2.0, which, when compared to the previous version, reduces lateral snag, unhampering the transition from SKI to WALK mode and reverse; a short rockered sole (only 304mm for 27.5); the central buckle system (45°) for maximum heel retention and superior downhill performance; a 3mm polyethylene layer provides adequate insulation. Thanks to the BUCKLE RETENTION SYSTEM, the tension of every buckle cable is guaranteed while walking. The sole is compatible with Dynafit bindings and all other touring bindings on the market. The ONE PX offers a newly developed TF – thermoformable liner with unbeatable fit, warmth and performance.

Dynafit One PX TF Ski Boot - Women's:   The ONE boot line combines the features of Dynafit’s lightweight TLT 5 boots with the features of the Vulcan/Mercury big-mountain boots: downhill performance with 60 degree cuff rotation for skinning back up. One boots also feature a Thermoformable liner, Pebax shell, Ultra lock buckle system, rockered sole and central buckle system for maximum heel retention. Weight 1300 g (size 25.5)

Evo (2014)
Serious ski tourists who put in the miles and pound out the vert but don't care for the stiffness or price point of the Vulcan will love the Dynafit One PX TF Alpine Touring Ski Boots. It sports an all Pebax® construction with the TLT 5-derived Ultra-Lock Buckle System and its stride-friendly 60˚ range of cuff motion. At 1490 grams in a 27.5, it also beats up on the competition in the weight category. Stiff enough for many to use as a resort boot, the Dynafit One really is what its name implies.

Oregon Mountain Community
The walk-friendly, fore-aft, 60° cuff rotation of the old TLT5 is featured in the Dynafit One PX-TF Alpine Touring boot. But as opposed to the more spartan TLT5, the One PX is more comfortable, easier to use, warmer, taller, cheaper and more supportive. And, importantly, pushes skis around better when charging down a bowl, couloir or tree shot, even on wide skis.


Following on the heels of the revolutionary TLT 5 boot, the ONE PX brings the same innovations to a wider range of customers, in greater comfort. It features the same tremendous mobility as the TLT series, but it is wider, warmer, stiffer (in ski mode) and more adjustable thanks to its 3-buckle design. Notable features include a cuff with the widest and smoothest articulation possible in the ski touring category; a new articulated cuff buckle system; a short, rockered sole for easy walking; and a 3mm polyethylene layer for extra insulation.


The One PX-TF Alpine Touring Boot was made to knock off peaks on your to-summit list. Lightweight, strong and aggressive, it will be your best touring companion, with never a complaint, never a whimper. And with women-specific design, thermo-formable liner, rocker sole, and walk mode, you'll be list-making all season.

Dynafit One PX-TF Ski Boot Reviews:


I took these for a few runs in a ski area during a demo, and pretty much immediately knew I needed a pair. They are unlike anything I've ever had on my feet. My husband has been skiing the Dynafit TLT5 and calls them his "mountain slippers" because they are so light. The awesome part, however, is that they get pretty stiff when they are buckled down, and can definitely shred.
These are an evolution from that TLT5 design, with one big difference that made me get serious about these: there are no stupid, extra tongues to carry around and deal with on your tour. I hate that!
I doodled around the base area a little with my heels unlocked and the range of motion was amazing. I've never felt anything like it! And have been skiing in the backcountry on Scarpas and Garmonts for the last 7 years.
The downhill performance was great. They got pretty stiff (a legit 110, from what I've been told), and I railed on some super firm groomers without a second thought.
Super light, easy to transition from hiking to skiing, excellent rotation for the climb, and a crazy heel pocket that locks you in... I can't wait to get these babies on some of our big volcanoes!

If these boots fit your feet (the #1 for choosing any touring boot), then you're in luck! I have been touring on these since last fall (going on 25+ days including one 45km day) and still am giddy about them when I strap them on. The range of motion while touring/walking is amazing (gets a bit getting use to) and I have been enjoying the speed and convenience of the one step transition into downhill mode (although sometimes you need to put a bit of muscle into it if you want to crank your boots up tight!) they are stiff enough to handle large powder skis and variable conditions - they won't feel like your downhill boots but the trade off is a nimble, light boot that performs respectably on the down.
After having a pretty high turnover of touring boots the last few years, these ones are here to stay!
