Aimed squarely at skiers who spend their days looking for the best snow on the mountain, without regard to where that might be, the Tecnica Mach1 120 MV Ski Boots sit a notch below the 130 flex Mach1 which can actually be an advantage in narrow spots and powder. With new and super secure contours in the C.A.S. (Custom Adaptive Shape) shell and liner, the Mach1 120 MV has both improved heel hold and better potential for modification than ever before.
