Gorilla Kai Traction Pad. Gorilla is designed to enhance the surfing experience with a superior product. Details include: A large template; Diamond III grove- a more spread out groove pattern allowing your feet to sink down and lock into the grip. The groove is more aggressive with more angular shapes and multiple levels to help you stay stuck; Cooperhead Arch- features a three dimensitional, tapered, delta shaped arch which helps lock the foot to the back of the pad for hard turning, with an increased sensitivity when the foot is forward in a trimming position; Block Wedge- a steeper more compact wedge to look your foot into place, while tappered at the rails to minimize water drag.
