A water-repellent, open-sole cycling overshoe. Lightweight and streamlined, the Caston is made for cycling footwear and more general trainers. Reflective detailing on cuff, back of overshoe and heel offers increased visibility at night. A Kevlar™ heel and toe is especially durable, handling the wear and tear of repeated crank arm and pedal contact. A rear zipper with pull loop increases practicality, while an open sole eases the process of clipping into pedals. The Caston is an essential when cycling. .
