Made to endure the colder seasons on the bike, these tech-savvy Winter Booties deliver supreme thermal protection in our most compact iteration to date. A reworked overshoe with an all-new ergonomic cut that eliminates wrinkles and an improved aerodynamic performance thanks to its zipless construction, these winter overshoes embody the essential characteristics of a must-have, lightweight, yet super warm shoe cover. Our internal test team classifies them as the convergence of an aero bootie and a warm winter overshoe with a blend of materials that lock out wind and water without compromising on their low weight or breathability. Sounds like prime riding equipment for winter, and these are certainly a product that we're excited about. For these Winter Booties, our fabric specialists have flexed their know-how to deploy their latest weapon against the elements. As your feet are so vulnerable while pedaling in bad weather, they've engineered the waterproof and abrasion-resistant Cordura on the toe area, while reserving our proprietary NEOS Medium on the ankle, which adds stretch, thermal protection and impermeability. Their compact, packable design is practical, so you can easily stow these overshoes if the temperature rise.
