Assos RSR Speed Sock - Black Series

An all-new sock developed with WorldTour feedback to maximize aerodynamic gains without requiring the extra layer of shoe covers. - To save every possible watt in the drag vs. speed binary, the RSR Speed Socks incorporate the same aerodynamic textile as our Speed Gloves and Speed Booties across the exposed ankle and cuff. The foot is built to transport moisture and maintain cool comfort, ensuring aerodynamics don’t come at the cost of comfort during hot races.
