Rosso Corsa Pro 9 Socks

Castelli Rosso Corsa Pro 9 Socks As engineered as a sock can get, the Rosso Corsa Pro 9 Cycling Socks from Castelli uses a 200-needle construction for maximum stretch and comfort. It has a compressive midfoot support band for arch support while cycling as well as a cushioning pad under the ball of the foot to improve comfort. Important for hot days, the socks have antimicrobial silver ions to reduce the odour that can form from sweat.
