Ski boot strap

What are booster straps?

Booster straps are elastic boot straps that replace or complement the upper buckle on your alpine boots. Unlike a traditional buckle that locks hard and statically, booster straps provide a more dynamic feel. They stretch under load and then return energy – making skiing smoother.

Benefits of booster straps

• Better pressure and power transfer between leg and boot.
• Reduces pressure points and makes the boot more comfortable.
• Makes skiing smoother through elastic response.
• Can be adapted to the skier's level – from amateur to elite.

How to install booster straps

1. Remove or loosen the upper buckle on the boot.
2. Attach the booster strap in the same mounts as the buckle or with the included screws.
3. Adjust the strap so that it sits tight but elastic over the ankle.
4. Test different stiffness levels (soft, medium, stiff) depending on your skiing style.

When are booster straps best suited?

• For competitive skiers who want more precision and feel in skiing.
• For recreational skiers who want to reduce uncomfortable pressure points in the boots.
• For freestyle and park skiers who want a softer and more flexible flex.
