BOOSTER STRAP WORLD CUP

Booster Strap World Cup

Engineered for elite ski racers and heavy-weight athletes requiring maximum stiffness, this flagship elastomeric strap provides uncompromising power transmission and instantaneous edge response. Constructed with a heavy-duty three-band elastic webbing system reinforced by an internal stiffening plastic shunt, it delivers the highest flex resistance in the Booster lineup. A micro-adjustable metal cam buckle secures the upper boot cuff directly to the shin, completely eliminating internal play, tongue lag, and mechanical slack.

By maintaining constant dynamic contact between the tibia and boot liner, the strap dampens severe high-speed vibrations and harsh impacts to eliminate shin bang during aggressive racing. The ultra-stiff elastic recoil maximizes kinetic energy return at turn exit, allowing rapid edge transitions and precise control on hardpack or icy race courses. Built to withstand extreme tension loads without slipping, it allows athletes to customize wrap tightness for optimal power drive and boot integration.
