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.
