The Tecnica Mach1 LV 120 Ski Boots hit the sweet spot for skiers seeking equal parts power and precision without the uncompromising feel of a full 130 flex boot. Their smooth flex is burly enough to power bigger skis without dialing things back, and bootfitter friendly features like grindable C.A.S. boot boards and easily punched C.A.S. shells mean they can be modified to accommodate higher volume feet with relative ease.
