The Mach1 LV 85 W is for the intermediate or lighter female skier, built on a women's specific narrower last. With a flex rating of 85, this boot features numerous fit solutions for the shell and liner, including a thermoformable cuff. Tecnica has covered the liner in lambswool with Celliant micro-crystals. These convert body heat into infrared radiation, which stimulates blood circulation thereby increasing warmth. The integrated Lift-Lock-System positions the buckles at a 45 angle when open, making the boot easier to put on and take off. Quick Instep offers easy entry and exit, and the balanced Women's Natural Stance make this a great blend of control, comfort and warmth for a wide range of female skiers.
