The Mach1 MV 95 W is a performance oriented-women specific ski boot built on a medium last. With a flex rating of 95, this boot features Tecnica’s C.A.S. (Custom Adaptive Shape) system with numerous fit solutions for the shell and liner, including a thermoformable cuff. Tecnica has covered the liner in lambs wool with Celliant micro-crystals. These convert body heat into infrared radiation, which stimulates blood circulation, thereby increasing warmth around the entire foot. The Women's Natural Stance puts you in the perfect balanced position to take you to the next level of skiing.
