The Two-Piece Ankle Strap contours to the shape of your boot and provides durability without extra weight. Urethane in the Slimeback™ Highback provides a smooth ride and allows for maximum lateral mobility. The C-Series Performance Chassis pairs an aluminum heelcup with a glass-filled nylon base tray. The aluminum heelcup provides the feel and durability of aluminum where you need it (heelside response) while the composite tray offers a damp and 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. Take this binding anywhere, any conditions we promise it won't disappoint.
