The Sidas Power Straps are engineered to enhance the flex of your ski boots, delivering improved ski control, precision, and overall performance. By incorporating an elastic strap, these Power Straps not only boost flex but also reduce pressure on the tibia when paired with the boot’s tongue, ensuring greater comfort throughout the day. Available in four flex levels (P1 to P4), from the softest to the stiffest, they allow you to fine-tune your skiing experience to match your preferences. Each strap features a durable metal buckle for powerful tightening and side reinforcement to protect against ski edge damage. Crafted from high-tenacity polyester with a redesigned buckle, these straps are built to perform even in the most demanding alpine conditions.
