Designed for the intermediate skier who prioritizes comfort, warmth, and convenience, the Mach Sport HV 80 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 80 flex will give them the performance they need for all-day on (and off) mountain comfort.
