The Mach1 HV 130, our high-performance model for skiers with high-volume feet. Mach1 stands for best-in-class all-mountain performance, promising a precise fit, the ultimate level of customization and efficient power transfer. The 130 flex with a 103 mm last is ideal for commanding skiers with wider feet or larger overall frames. The boot feels surprisingly comfortable out-of-the-box, but if needed, you can add personal customization with Tecnica's C.A.S. system to solve any additional fit problems. Demanding skiers will appreciate the Asymmetrical Power Transmission shell, which efficiently transfers all of your energy directly into the turn. The Mach1 HV 130 delivers a level of power, comfort and control that you've never seen before in a high-volume boot.
