Castelli Toe Thingy: Keep your feet warm without the hassle of a full shoecover. Made from super-durable neoprene, these toecovers slip easily over the front of your shoe and are held in place by the cleats. The rugged underside of the toe will add grip and resist rips or tears thanks to a silicone print. This can be worn on its own or as a layer between your shoe and shoecover.
