Dynafit One U-TF Randonee Boots -

The lightweight Dynafit One U-TF randonee boots balance a progressive flex with great walkability so you can ski those steep backcountry lines you've always dreamed about.



  • Polyurethane shells and cuffs offer similar performance to the popular TLT5 Mountain boots, but are a touch wider in the forefoot for a more comfortable fit
  • Lightweight thermo-formable (TF) liner for superior fit, warmth, energy transfer, and performance

Lining and Layers:

  • Expanded polyurethane insulation layer is glued to the insides of the shells to help keep your feet warm on frigid winter days


  • Central magnesium buckles are positioned exactly on the shell pivot points to keep your heels in place when you're skinning uphill and skiing back down

Weather and Wind:

  • Compact shells with rockered soles provide excellent walkability and nimbleness when you're booting up steep snow slopes or scrambling rocky ridges


  • Flexible tongue design doesn't interfere with the cuff rotation for comfort when touring


  • Power straps help close the boots securely around your legs


  • Ski/walk mechanisms can be set between 15° and 18° of forward lean, as well as loosened for walking
  • Dynafit One U-TF randonee boots have self-guiding notches located at the inserts at the toes of the boots to ease stepping into Dynafit bindings
  • 15-18 degrees of forward lean, and 60-degree cuff rotation in walk mode, to accommodate whatever the movement
  • Lightweight liners are premolded on anatomic lasts for use right out of the box; or, have the liners custom molded to your feet by a qualified ski shop employee
  • Opening the Ultra-Lock magnesium cuff buckles simultaneously changes the boots from ski to walk mode for fast, effortless transitions
  • PU (polyurethane) shell for durability and a resilient flex
  • PU cuff and driving spoiler adds stiffness to the shell, holds heel in place, and features an adjustable lean angle
  • Dynafit Pro, a durable, sticky rubber sole for sure, secure footing
  • Compatible with Dynafit Quick Step-In or standard touring binding
  • Cuff and central buckles are designed with a retention system to prevent unwanted release
  • Magnesium Ultra-Lock System for quick, easy release connected to walk mode
