Assos Rain Booties Assos have taken inspiration from their aerodynamic EQUIPE RS Rapidfire Chrono Booties, building an aerodynamic, wind-cheating shoe cover that also happens to be waterproof and highly visible. These booties are a versatile accessory, suitable for all seasons. Wear them to protect your feet during the rainiest mid-season days, when the roads are dirty and wet in winter.
