The C-Series Performance Chassis pairs an aluminum heel cup with a glass filled nylon base tray. The aluminum heel cup provides the feel and durability of aluminum where you need it while the composite tray offers comfort and a smooth ride. Urethane in the Slimeback™ Highback provides a smooth ride and allows for maximum lateral mobility. The canted footbed aligns your joints with a 2.5 degree angle while providing more leverage over the tip and tail of your board. Two-Piece Ankle Strap contours to the shape of your boot and provides durability without extra weight. The C-6 is designed for all around performance and a rider that prefers the smooth feel of a composite tray.
