Fluidity and power.

Put your knee on the Sidewall Surf, more flexible and lower. Hang on and drive on the Sidewall Power, more rigid and higher. Take turns with comfort and power. Reactive Highback cradles your shoe and removes pressure points at the top of the highback. The Airform ankle strap adapts to your shoe thanks to independent pressure cushions, eliminating the pressure points and allowing flexion without pinching points.
