Abstract: A cycling shoe cover is designed to provide maximum protection from the elements such as rain, snow, and cold. It also provides aerodynamic benefit with minimum weight. The cover is flexible unitary made from an elastomer, such as silicone or latex rubber, and is highly elastic and waterproof. The upper part of the cover fits snugly over the cyclist's ankle to prevent water egress into the shoes from above. The lower part of the cover snugly cover and seals to the bottom edge of the shoe without interfering with the cycling shoe's cleat or attachment to the cycle pedal.
