The flex of your ski boots is essential for the control of your skis, and therefore your performance. 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.
