Compressive Cool Mesh — Rosso Corsa Pro

The best sock ever made for performance cycling, designed for every cyclist to enjoy. The Castelli Rosso Corsa Pro 15 Sock is a high-quality, cooling sock that keeps the foot comfortable after long days in the saddle. Fitted with cool mesh, a padded forefoot, compression midfoot, and even a reflective tab at the back.

Constructed with Meryl® Skinlife yarn, these socks feature unique antimicrobial silver ions that reduce the prominence of odor-causing bacteria. The 200-needle design allows for extra stretch, which fits your foot and won't fall mid-ride. A multiple-structure knit gets the right performance in every part of the sock, including a compressive midfoot support band that enhances circulation. With a cushioning pad under the ball of the foot, these socks deliver world-class power with comfort that lasts all day long.

The Castelli Rosso Corsa Pro 15 Sock has everything you need for a truly unforgettable ride. An asymmetrical construction mirrors the shape of the foot, so each sock is identified as either right or left. No more uneven wear and tear here! A reflective tab at the center back even promotes visibility so you can live it up when the lights go dim.
