The RaceThermo Hi-Vis is a fully windproof and waterproof insulating shoe cover, ideal for cold and wet days on the road. Its high-visibility features enhance your safety when you're out in low light conditions. Made from 4 mm waterproof neoprene, the RaceThermo is equipped with IntelliSeal, a brilliant technology that significantly increases both durability and water resistance. The RaceThermo Hi-Vis also rethinks the traditional way of putting on shoe covers. This zip-free shoe cover is put on before wearing the shoe. This offers several advantages: it greatly improves the ease of putting it on and the fit on the shoe, provides a better fit across a wider range of shoes, and the absence of a zipper means no chafing, resulting in a more minimalist feel and better waterproof properties.
