Bicycle Shoes Covers are a fairly common accessory in every cyclist's wardrobe. Used with cycling shoes, they come in different sizes and shapes, for different weather and different materials. In summer, small toe covers are most often used. In addition, in time trial races, such a thing helps to give aerodynamics. In the off-season - in spring and autumn - bicycle shoe covers protect your feet from water, mud, and wind. In winter, the primary task of shoe covers is to warm your shoes and prevent the cold wind from blowing them.
