What used to be a holy sock is now one of the peloton's top fashion accessories. The Castelli Belgian Bootie 3 Shoe Covers are made of abrasion resistant and easy-cleaning polypropylene fabric. A double layer knit on the body of the foot makes them extra durable. The cuffs are tall enough to cover 9 cm socks, and feature silvery reflective bands in addition to the trademark Castelli logos.
