Whether the snow Gods have delivered or not, the Mach1 HV 120 TD is a high performance ski boot designed 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 Mach1 HV 120 TD delivers the same level of performance as our top-of-the-line 130, but with a slightly more forgiving flex. T-Drive Technology, a cuff-to-shell interface, fundamentally improves the boot’s power transmission, provides a smooth, progressive flex and increases energy efficiency allowing you to ski longer with less fatigue. It also provides a consistent flex throughout changing temperatures. The anatomically shaped shell and liner provides a comfortable out-of-the-box fit. If needed, you can add personal customization with Tecnica’s C.A.S. system to solve any additional fit problems. Advanced skiers will appreciate the Asymmetrical Power Transmission shell, which efficiently transfers all of your energy directly into the turn. For crushing hot laps from bell to bell with precision and comfort, the Mach1 HV 120 TD is the boot you want to step into.
