The original RSR Socks were developed with WorldTour feedback; the S11 generation was refined in the same way, specifically designed for high-intensity racing across long distances in hot conditions. The InfraRed yarns have a high percentage of elastomer for compressive support throughout, blended with Lycra to deliver a firm, supportive hold along the foot, ankle, and lower leg. The 21cm (9in) cuff and clean, understated aesthetics match any Racing Series layering system.
