All the Mach1 line is available in 3 different volumes, because we strongly believe that the products must adapt to people, and not the other way around. We are literally obsessed by the fit and to get the best result we use the inside-out approach. That means that we start from the anatomy of the foot and we build the liner around it. The dual-density C.A.S. (Custom Adaptive Shape) material helps us to precisely mirror the anatomy. Than we build the shell around it. This gives us the precise and comfortable fit from the first try and a very low pack out rate.The Mach1 MV 120 is a high performance ski boot designed for advanced to expert level skiers with medium volume feet who are looking for a comfortable but precise fit and a high level of customization. Grounded in the fundamentals of ski boot design, the MV 120 features T-Drive technology that allows the boot to function in a much more efficient way. Developed with an anatomically shaped shell and liner, the C.A.S. technology provides a great fit right out of the box but allows the boots to be fully customized if need be.Liner Customization:
