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.

Features

• Windchannel Stripes is an all-new, aerodynamic Lycra blend warp knit that melts across your skin with no folding or creasing, reducing drag more than bare skin alone. This bi-stretch textile grants light compression and stabilizing grip to the cuff. The foot is composed of fast-drying, cooling yarns.
• An 18cm (7in) cuff extends the aerodynamics without violating UCI regulations, and the material composition maintains fit without the need of silicone grip.
