Castelli's Endurance 15 socks are highly durable and extra comfortable, making them ideal for hard conditions and long rides. The 200-needle construction adds extra stretch for complete freedom of movement and a midfoot support band prevents the bunching of material within the shoe. Bioceramic yarns help to manage moisture and reduce bacterial growth, keeping the feet fresh. Under-foot cushioning soaks up some of the shock that can come from riding on rough roads and the toe and heel areas are reinforced to enhance longevity.
