The Sidas Power Straps are designed to enhance the flex of your ski boots, improving ski control and overall performance. By using an elastic strap, these Power Straps not only boost flex but also provide added comfort to the tibia when combined with the ski boot’s tongue. Available in four different flex levels (P1 for the softest flex to P4 for the stiffest), they allow you to customize your ski experience to suit your preferences.

Each strap features a durable metal buckle for precise and powerful tightening, as well as a side protection reinforcement to guard against damage from ski edges during use. Made with high-tenacity polyester and featuring a redesigned buckle, these straps are built to perform in the most demanding conditions.
