The Reversible Ankle Strap provides two riding positions. Ride with the stiff part of the strap on the top for a more aggressive feel or swap the straps so the soft part is on top for more flexibility and lateral movement. The A-Series Aluminum Chassis provides the reactive flex and power transfer of aluminum with less rigidity than previous designs. The Cored Nylon Highback reduces weight, while still providing a responsive ride. The canted footbed aligns your joints with a 2.5 degree angle while providing more leverage over the tip and tail of your board. Integrated rubber pods make for an even smoother ride. The TPU basepad damps out high-speed vibrations. The A-8 is designed for an advanced rider that's looking for all-mountain performance.
