RSR BOLIDE Socks S11

What Our Gearhead® Experts Are Saying:

“These are as close as you get to TT booties in sock form. The aero textile is legit—smooth, compressive, and fast—and the cooling foot material keeps things from overheating in long efforts. The grip on the cuff is perfect for hard racing where every watt matters.”

Purpose-built for WorldTour racing, the Assos RSR Bolide Socks S11 integrate aerodynamic performance with precise thermoregulation for intense, sustained efforts. The 550CX warp-knit textile on the lower leg provides a bistretch, second-skin wrap that reduces turbulence and smooths airflow at the critical leading edge. This highly elastic construction conforms seamlessly to the leg, maintaining consistent aero alignment throughout varying pedaling dynamics.

In the footbed, a blend of polyamide, polypropylene, and elastane creates a fast-drying, air-cooling structure ideal for high heat and high output. This ensures moisture transport and breathability remain exceptional even during threshold climbs, time trials, and technical crit surges. The UCI-legal 18cm cuff height maximizes aerodynamic gains while integrated silicone grip maintains position under aggressive accelerations or extreme temperatures.

Designed for riders chasing every possible watt, the RSR Bolide Socks S11 pair professional-level aerodynamic engineering with uncompromising comfort—essential gear for competitive racing across road, TT, and elite training environments.
