Ski boot craftsmanship is still a living art, and the update to our Mach1 LV 120 is further proof. Tecnica has once again improved performance, fit, and customization options in this all-new version. To give you the confidence needed to progress, Tecnica has modernized the LV while staying true to the benefits of the Custom Adaptive Shape (C.A.S.) system. A brand-new T-Drive system ensures a smooth and progressive flex while also making the boot easier to put on. First-class design, fit, and performance.
