Chaussettes vélo Assos RSR Bolide Socks S11 2026

The RSR BOLIDE Socks S11 are the result of Assos’s most advanced aerodynamic development, tested and validated at the highest level of the WorldTour. Designed to eliminate the need for shoe covers, they offer a high-performance, lightweight and breathable solution, ideal when every watt counts.

The ankle section uses a specific low-drag fabric, optimised in a wind tunnel as part of the ASSOS AeroScience programme. Its compressive structure creates a smooth transition between the leg and the shoe, significantly reducing turbulence. The foot section, meanwhile, features a breathable, lightweight mesh, ensuring comfort and rapid moisture wicking even during maximum effort.

With a 19 cm cuff height, compliant with UCI regulations, the RSR BOLIDE Socks S11 are clearly designed for race-day use. For perfect stability in race conditions, the use of an adhesive spray is recommended.
