The Tecnica Women's Mach1 MV 95 Ski Boots are 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 lamb's wool with Celliant micro-crystals. These convert body heat into infrared radiation, which stimulates blood circulation, thereby increasing warmth around the entire foot for all-day comfort. Also made with Women's Natural Stance design that puts you in the perfect balanced position to take you to the next level of skiing.
