This Boot is So Good. I can say this because I skied in it all last season.I was super impressed with this new Mach model. It's out of the box fit is great. The liner is super comfortable and the 120 flex is perfect for hitting the entire mountain.
This boot is for advanced to expert skiers the Mach1 120 is the perfect solution for
someone that doesn’t want to compromise fit and performance but is
looking for a slightly softer flex than the 130 in a medium volume,
100mm last. The proven C.A.S. liner is now joined by the new C.A.S.
Shell and C.A.S. Bootboard offering a great out-of-the box fit with
amazing customization capabilities. No compromises!
