These third-generation aero socks combine a soft woven foot section with silicone grippers at the cuff to keep them firmly in place on the calf during rides. Designed for aerodynamic performance, the woven foot construction provides everyday comfort and traction, making them suitable for both training and racing. Sizing is best determined by calf circumference rather than foot size, and the socks lay flat at 6.5 inches (16.5 cm), stretching to approximately 8 inches (20 cm) when worn.
