These overshoes have been developed in accordance with the UCI Maximum Aerodynamics Regulations for Time Trial. The development process included CFD analyses, extensive material investigations, and practical tests in the wind tunnel. The smooth and silicone-coated foot area optimizes the wind attack surface, while the grooved leg area provides ideal air separation. These overshoes are extremely high and extend to the calf muscles. There is virtually no reason to use them in road racing. Their maximum advantage, however, is in the high-speed range in time trials.
