The final touch of aerodynamics, an ultrabreathable racing sock engineered to minimize drag when shoe covers aren’t feasible.

Developed and continuously refined with WorldTour feedback, the RSR Speed Socks S11 incorporate an aerodynamic textile across the lower leg. The foot portion is engineered to transport moisture and maintain cooling airflow, ensuring aerodynamics don’t come at the cost of comfort. Grip on the UCI-legal 18cm (7in) cuff adds stability in hot, intense racing conditions.

FEATURED FABRICS: Wrapping the lower leg, 550CX is a breathable, bi-stretch warp-knit textile with inherent aerodynamic properties and a highly elastic second-skin fit. The foot is composed of fast-drying, aircooling yarns.

CONSTRUCTION/FIT: An 18cm (7in) cuff extends the aerodynamic gains without violating UCI regulations, and Circular Seamless construction eliminates seams and friction across the foot.
