Rapha Pro Team Winter Socks

Rapha Pro Team Winter Socks are cycling socks designed for wearing on higher tempo rides in the cold. In contrast to the usual thick fabrics used, the Pro Team Winter Socks are made of a lower volume, ultralight, fast-drying yarn that has exceptional insulating qualities. The toe and heel boxes of the socks feature a nanoglide technical yarn to reduce/prevent rubbing.
