Assisted Performance System amplifies your input to the boot through the mechanical advantage of Lange's 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 110-rated flex, this boot gives intermediate skiers a strong platform for pushing their skiing forward. At 97mm wide, our low-volume last complements the thermoformable liner for a comfortable performance fit.
