Booster Straps give you the maximum ski boot performance, extraordinary ski control and shin protecting shock-absorption. Skiers with boot flex indices between 110 and 140, including athletic and advanced recreational skiers Why It Matters Elite-Level Control: The three-layer elastic design dramatically improves boot-to-leg contact, giving skiers better responsiveness, power transmission, and precision edge control. Refined Performance Feel: Although it doesn’t physically stiffen the boot, the strap adjusts how flex is perceived—meaning you feel sharper response from the first turn. Shin-Bang Reduction: With its cushioned elasticity, this strap softens forward movement and helps prevent painful shin impact—keeping rides smoother and more enjoyable. Installation Made Simple Place the strap directly against your inner liner’s tongue. Stretch to your desired tension for a snug connection. Secure it—no bulk, no extra bulk upward in your cuff.
