ASSOS RSR Speed Socks S11 – Series II

The ASSOS RSR Speed Socks S11 are high-performance racing socks designed to provide an aerodynamic advantage without the need for separate shoe covers. Developed using WorldTour feedback, they combine an aerodynamic lower-leg fabric with a lightweight, highly breathable foot section for fast riding in warm conditions.

Key Features

  • Aerodynamic 550CX lower-leg fabric helps reduce aerodynamic drag.
  • 18cm / 7-inch cuff provides a race-ready silhouette while remaining within UCI regulations.
  • Second-skin fit with highly elastic, bi-stretch construction.
  • Fast-drying foot section helps move moisture away while promoting cooling airflow.
  • Circular Seamless construction reduces seams and friction around the foot.
  • Grippy cuff helps keep the sock securely positioned during hard efforts.
  • Designed specifically for warm-weather racing and high-intensity riding.

Aerodynamic Performance

The key feature is the 550CX textile around the lower leg. Its textured, bi-stretch construction is designed to improve airflow over the leg while maintaining a close, wrinkle-free fit. This makes the RSR Speed Socks particularly useful when riders want some of the aerodynamic benefits of overshoes without adding another layer around the shoe.

Best Suited For

  • Road racing
  • Time trials
  • Criteriums
  • High-speed group rides
  • Gran fondos and fast endurance events
  • Warm-weather training
  • Riders looking for an aero sock alternative to shoe covers

The ASSOS RSR Speed Socks S11 are a premium race-day choice for riders looking to optimise both aerodynamics and cooling performance.
