The Castelli Free Kit 13 Socks epitomize clean, race-ready style with century-conquering comfort and an of-the-moment cuff height. Made from durable, quick-drying Meryl Skinlife yarns, this sock whisks moisture away from your feet as you ride and keeps offensive aromas at bay on especially hot days. Castelli adds a supportive band across the arch and uses a medium compression knit throughout the sock's body to prevent bunching or chafing as you ride.
