RSR BOLIDE Socks S11

What Our Gearhead® Experts Are Saying:

“These feel like pure race gear. The aero textile on the lower leg is incredibly smooth and supportive, and you can actually feel the difference when you’re in a deep tuck. The foot stays cool thanks to the quick-dry yarns, and the cuff grip keeps everything locked down—even in brutal heat. They’re my go-to for hard efforts and race days.”

We lace up the Assos RSR Bolide Socks S11 when aerodynamics matter just as much as comfort. Built with direct input from WorldTour riders, these socks wrap the lower leg in Assos’ 550CX warp-knit textile—an aero-engineered, bi-stretch fabric that smooths airflow while providing a true second-skin fit. In the footbed, fast-drying, cooling yarns keep us comfortable through surges, climbs, and full-gas race efforts, ensuring speed never comes at the expense of breathability.

The 18cm UCI-legal cuff height delivers maximum aerodynamic efficiency, and integrated grip ensures stability when heat and intensity ramp up. Whether we’re racing a crit, tackling a time trial, or hammering a decisive breakaway effort, the RSR Bolide Socks S11 give us a noticeable advantage on speed, comfort, and consistency.
