The Mach Sport HV 120 is a boot built to maximize comfort, without necessarily sacrificing the performance you might lose on a softer flexing boot. Featuring Tecnica's highly customizable Custom Adaptive Shape (C.A.S) technology - these boots are as customizable as they come, and with 102mm last, they're designed to fit an assortment of wider foot shapes right out of the box. *note, these have aftermarket lange liners in them*
