Assos RSR Cycling Socks S11
The Assos RSR Cycling Socks S11 are elite racing socks designed to World Tour standards, offering medical-grade compression with a lightweight, cooling construction suited for high-intensity, long-distance rides. Constructed with advanced InfraRed yarns, these socks provide 25mmHg (second-class) medical compression that enhances circulation and minimises muscle fatigue, keeping feet, ankles, and lower legs fully supported during demanding races. The ultralight fabric blend of elastomer and Lycra delivers a firm yet soft hold, maintaining breathability and comfort in hot conditions.
With a streamlined 21cm (9in) cuff and seamless, low-profile design, the RSR S11 socks offer a smooth fit free from friction and pressure points, ideal for pairing with Assos’s Summer RSR or RSV systems. Their understated aesthetics complement any racing kit, while the high-elasticity fabric ensures a snug, stable fit that stays put throughout intense efforts.

About Assos
Swiss precision. Half a century of obsession.
Assos of Switzerland was founded in 1976 by Toni Maier-Moussa with a single ambition: reinvent cycling apparel from the inside out. The Lycra cycling short, modern bibs, the chamois as we know it — all began here. Half a century later, the obsession with precision and ride feel hasn't moved an inch.
Assos still designs and engineers every piece in Switzerland. The brand operates its own laboratory, its own development pool of test riders, and its own assembly line for the most demanding garments in the range.
