Shadow 140 LV Pro Ski Boots 2025

The Lange Shadow 140 LV ski boots bring a new level of power transfer, vibration absorption and comfort to all-mountain skiing. Our Assisted Performance System amplifies your input to the boot through the mechanical advantage of our 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 140-rated flex, this boot gives expert skiers every advantage for skiing any terrain on the mountain. At 97mm wide, our low-volume last complements the thermoformable liner for a comfortable performance fit.
