The Assos RSR Speed Socks S11 are the ultimate finishing touch for your aerodynamic setup. These ultra - breathable racing socks are expertly designed to reduce drag when shoe covers aren't an option. Developed with feedback from the WorldTour and constantly improved, they feature an aerodynamic textile on the lower leg. The foot part is crafted to quickly wick away moisture and keep a cool airflow, so you get top - notch aerodynamics without sacrificing comfort. The UCI - legal 18cm (7in) cuff has a grippy design, providing extra stability during hot and intense races. The 550CX fabric wrapped around the lower leg is breathable, bi - stretch, and warp - knit, with built - in aerodynamic features and a snug, second - skin fit. The foot is made of fast - drying, air - cooling yarns. The 18cm (7in) cuff extends the aerodynamic benefits while staying within UCI rules, and the circular seamless construction gets rid of seams and friction on the foot. Composition: Foot - 80% Polyamide, 10% Polypropylene, 10% Elastane; Ankle - 82% Polyester, 18% Elastane.

How to use: Simply put on the Assos RSR Speed Socks S11 like you would any other socks. Make sure the 18cm cuff is properly positioned on your lower leg. They're great for high - intensity races or training sessions. Note: These socks are UCI - legal, but always double - check the specific regulations of your event. Maintenance: Wash them in cool water to keep the fabric in good condition. Avoid using harsh detergents that might damage the fibers. After washing, let them air dry. Don't put them in the dryer as high heat can shrink or damage the elastic materials.
