SealSkinz Caister Single Layer Mid Sock
Socks That Work as Hard as You Do.
Engineered for comfort and endurance, these mid-length cycling socks are crafted from a highly breathable, moisture-wicking fabric blend to keep feet cool and dry. A mid-foot grip locks the sock in place for a secure fit, preventing slipping and rubbing inside the shoe. Hand-linked seams reduce friction and irritation, minimizing the risk of blisters. With ventilated knit mesh across the top of the foot, airflow is maximized for lasting comfort on every ride.
