Sidas Powerstrap P3

Notify me when this product is available:

How your boots flex is important as they control your skis and how you perform on the slope. The Sidas Powerstrap wraps around the top of the boot to provide improved flexion and comfort where the shin meets the tongue of the liner. They are constructed from different levels of elastic to create straps with varied resistance and rebound properties, this allows you to pick one that best suits for ability and needs. P3 is for strong skiers who want plenty of power and control, but also want a slightly forgiving product. The metal buckle provides a strong grip for the strap and powerful tightening, and the side is reinforced to protect it from ski edges while in use. Powerstraps will need to be screwed onto your boots in place of the brand-fitted ones and they come with 4 screws and 4 grip inserts to do this.
