About Sidas Power strap

Essentially a rebranded Booster strap. Pictured is a P3.

The use of an elastic strap improves this flexion whilst improving shin comfort with the tongue. Our power straps are constructed with 4 different elastic levels, from the softest (P1) to the stiffest (P4), to allow you to adjust the control of your skis to your liking. The straps are equipped with a metal buckle for precise and powerful tightening as well as side protection reinforcement to protect the strap against edge hits during use.
