Castelli Rosso Corsa Pro 15 Sock White, Xxl

Castelli claims the best sock they've ever made for performance cycling is the Rosso Corsa Pro 15 Sock. And, they might be right. It's constructed from multiple-structure knit with extra stretch and a compressive midfoot support band. An asymmetrical construction mirrors the shape of the foot, and Meryl Skinlife yarns with anti-odor silver ions reduce odor. A cushioning pad under the ball of the foot adds comfort, and there's even a reflective tab at the back.
