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.
