ATHLETIC FOOTWEAR AND CLEAT SYSTEMS AND METHODS
20220015504 · 2022-01-20 ·

Athletic footwear and cleats comprise a first molded layer comprising a rigid substrate including a hole for connecting the molded layer to a shoe, and wherein the first molded layer is adapted to engage binding elements of a pedal, and a second molded layer formed on the bottom portion of the first molded layer, the second molded layer substantially conforming to a shape of a portion of the first molded layer. The second molded layer forms a soft walking surface adapted to provide traction with a walking surface and a raised portion formed thereon, the raised portion adapted to impact float friction during operation. The first molded layer may include nylon, and the second molded layer comprises a thermoplastic elastomer, a thermoplastic polyurethane, and/or a silicone substrate. A third molded layer may be provided to reduce contact friction between the cleat and the pedal of an exercise cycle.
