RSR Socken S11

The RSR Socks S11 are the core race-tier sock of ASSOS's RSR family in the current S11 generation. The family branches into named specialists — Speed for fast dry days, Bolide for the aero programme, Superleger for the ultra-light build, Thermo Rain for foul weather — and this is the sock they branch from: the standard RSR for race days and hard training without a niche brief. If you own one ASSOS race sock, this is the default.
