Using these shoe covers is easy. Just unzip them, slip your cycling shoes in, and then zip them up. When using, make sure the covers fit snugly on your shoes to keep out wind and water. As for maintenance, after each use, wipe them down with a dry cloth to remove dirt. If they get really dirty, you can wash them with mild soap and water. Let them air dry completely before storing. Keep them in a cool, dry place to maintain their quality.
