WHAT IT IS / PRODUCT FEATURES The fastest footbeds for your feet. Developed for the high speeds achieved during time trials. The result of the fast feet project - time trial leg warmers. Developed in collaboration with the Pro Tour team for extra speed during time trials. Silicone coated elastic material around the leg warmers for improved aerodynamics. Lycra cuff with grooves helps to separate air from the foot. Polyurethane tape on top keeps the warmers in place.Sizes: S(36-39), M(40-42), L(43-44), XL(45-46), XXL(47-48).

The time trial socks are designed for maximum aerodynamics, within UCI technical limits. Developed using CDF analysis, a multitude of fabric samples and wind tunnel testing. The stretchy, smooth, silicone-coated base perfectly hugs the shape of the trisuit, while the grooved cuff helps to separate the air circulating around the foot. The covers are high to cover the leg up to the calf. We don't see why you can't wear them during a road race, but they'll maximize your performance especially during a time trial.
