The XT3 130 is Lange's stiffest ski boot built for backcountry touring, freeride, and big mountains. Its 130 flex prepares you for steep lines, rowdy cliffs, and cruising icy aprons at top speeds. Lange paired its professional-level performance with an equally comfortable fit for more skiers out there. The 100mm last is a perfect balance of roomy comfort and a precise fit, and the Dual 3D Full Liner includes Ultralon foam for easier thermo-molding in key areas. This boot also boasts a burly latch that stays secure in ski mode, and unlatches for a massive 53° range of motion.
