The Tecnica Mach1 MV 105 W is a sporty women-specific ski boot built on a medium last. With a flex rating of 105, this boot features Tecnica’s C.A.S. (Custom Adaptive Shape) system with numerous fit solutions for the shell and liner, including a new 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. The integrated Lift-Lock-System is a further highlight as it positions the buckles at a 45° angle when open, making the boot easier to put on and take off.
