The Sidi Frost Gore-Tex Winter MTB Shoes addresses the needs of cyclists who require more protection against cold and moisture without the added bulk of a winter bootie. These shoes are constructed with a combination of Microfiber and Microtech Mesh, with a Gore-Tex waterproof membrane to provide a water resistant upper. The competition sole offers performance on and off the bike, with plenty of rigidity for efficient power transfer, but just enough flex for comfort. Tecno 3 Buckle System allows easy on-bike fit adjustment, while the internal gusset protects from the cold and water when the weather is humid. SPD cleat compatible.
