The two-piece ankle strap conforms to the shape of your shoe and provides durability without added weight. The urethane of the Slimeback™ Highback offers a smooth glide and allows maximum lateral mobility. The C Series performance chassis combines an aluminum heel cup with a glass-filled nylon baseplate. The aluminum heel cup provides the feel and durability of aluminum where you need it (heel response), while the composite deck provides a wet, responsive glide. The angled sole aligns your joints at a 2.5 degree angle while providing more leverage on the tip and tail of your board. This binding will adapt to all circumstances and will not disappoint you.
