Booster Strap - World Cup

Product description

Booster Straps give you the maximum ski boot performance, extraordinary ski control and shin protecting shock-absorption.

A good rule of thumb is to match the flex index of the boot with the model Booster Strap. Also remember there is a grey area between models. Less than 100 flex – Intermediate, 110 to 130 –Expert, and greater than 130 the World Cup.
