Lange's Assisted Performance System amplifies your input to the boot through the mechanical advantage of their Dual Pivot and Suspension Blade technology. The design boosts input by up to 26%, giving you more power and control with less energy. The boot's clean, consistent flex is combined with increased shock absorption through the shell for enhanced snow feel and contact. Like a full suspension bike, the combination lets you ski longer and more efficiently. Together with a 95-rated flex, this boot gives intermediate and advanced skiers a strong platform to keep pushing their skiing. The women's-specific shell and Lange's 100mm-wide, medium-volume last complement the thermoformable liner to offer all-day comfort. Combined with an asymmetrical toe box and enhanced insulation, the liner offers foot-hugging comfort and warmth that lasts all day.
