The boot feels surprisingly comfortable out-of-the-box, thanks to the anatomically shaped liner and shell. But if needed, you can add personal customization with Tecnica’s C.A.S. system to solve any additional fit problems. Merino wool and Celliant combine in the liner for increased warmth, while the C.A.S. Cuff Adapt System quickly and easily adjusts volume to fit a variety of lower leg shapes. The Women's Natural Stance puts you in the perfect balanced position and the Asymmetric Shell Design allows you to access all the energy and power of the ski. A great fit with a high level of performance, the Mach1 HV 95 W provides the foundation you need to get after it on the mountain.
