The Sidas Power Straps are designed to enhance the flex of your ski boots, improving control, precision, and overall skiing performance. Featuring an elastic strap, they not only boost flex but also reduce pressure on the tibia when combined with the boot’s tongue, delivering added comfort and smoother power transmission.
Available in four flex levels (P1 to P4)—from the softest to the stiffest—they allow you to customize your setup to match your skiing style and performance needs. Each strap includes a durable metal buckle for powerful tightening and side protection reinforcements to prevent damage from ski edges. Built with high-tenacity polyester and a redesigned buckle, these straps are made to withstand demanding alpine conditions.
