Designed for the beginner to intermediate skier who prioritizes comfort, warmth, and convenience, the Mach Sport HV 70 is specially built for skiers with higher-volume feet. An anatomical 103-mm last combined with a Comfort Celliant liner enhances circulation for optimized warmth and performance. If needed, you can add personal customization with Tecnica’s C.A.S. system to solve any additional fit problems. Double Quick-Instep and Lift-Lock buckles make for easy entry and exit, and the 70 flex is our most forgiving for all-day on (and off) mountain comfort.
