Castelli Rosso Corsa Pro 15 Sock -- Black S/M

Castelli claim the Rosso Corsa Pro 15 is the best sock they have ever made for performance cycling. Cool mesh, padded forefoot, compression midfoot, and even a reflective tab at the back. We think Castelli may be right!

- Multiple-structure knit to get the right performance in every part of the sock

- 200-needle construction for extra stretch

- Compressive midfoot support band

- Asymmetrical construction to mirror shape of foot

- Reflective tab at center back

- Cushioning pad under ball of foot

- Meryl® Skinlife yarns with antimicrobial silver ions to reduce odor
