Booster Strap Ski Boot Strap - Soft
- A few left in stock - ships immediately

Product description
Booster Strap Ski Boot Strap - Soft is a pair of elastic replacement straps for alpine ski boots with a flex of under about 100.
The softest in the Booster family: Soft provides even, progressive pressure against the liner tongue. The result is closer contact with the boot without the cuff feeling unnecessarily stiff.
How to use the product
- Remove or loosen the boot’s existing power strap according to the boot’s design.
- Mount the Booster strap on the back of the shell with the elastic section against the liner tongue.
- Tighten the strap so that the elastic stretches about 2-3 cm as a starting point.
- Test ski and adjust - if the difference feels small, the strap is often too loose, and if it pushes you backward, it is too tight.
- Have a bootfitter install the strap if the boot requires new screw holes or another type of attachment.
