Made of 4 mm thick fleece lined and waterproof neoprene, the covers offer maximum insulation and water repellence. These shoe covers are also equipped with IntelliSeal™, a smart technology that greatly improves wear resistance and water rejection thanks to rubberized seams at the lower edge of the shoe cover. With Arctic Hi-Vis shoe covers you can keep on cycling, no matter how cold, dark or wet the winter gets.
