We have totally redesigned our road cycling shoe covers to make them more durable, easier to get on, and easier to care for. They are still made from our signature, lightweight, waterproof material but we have reinforced the bottom of the shoe covers so they last longer. We hope you are as excited about this update as we are! CARE INSTRUCTIONS: To clean shoe covers/overshoes, wipe with a cool, wet cloth. Do not put shoe covers in clothes washer. To dry, hang shoe covers/overshoes over a hanger or ledge or wipe with a dry cloth. The material does not absorb water, so they should dry quickly. Do not put shoe covers/overshoes in clothes dryer.
