They work. Light weight. Secure holding when locked down.


  • Light weight
  • Secure


  • Brakes not large enough

Enjoyed using these bindings this last winter. A few challenges learning how to get locked in and managing the steps but after the second trip, things were good. You can, with a pole tip, turn the heal piece all the way around to switch from walk to ski or back. Took some practice.  

Though I am a lightweight, have no problems carving the hard pack on the way back to the lodge. These are much better than the clunky first pair of bindings I had.
