When every second counts.
Your TT rig is prepped for the race with a set of deep-dish wheels and perfectly placed aerobars while a pointy helmet and dimpled skinsuit wait in the wings. Now you just need a set of fast shoe covers to streamline the bumps from those bulky ratchets and seam edges. Utilizing technical fabrics and a sleek design, the Castelli Aero Race Shoe Covers MR might just be the most aerodynamic shoe cover on the market.
Using CFD computer modeling and wind tunnel testing, Castelli developed a shoe cover that encourages airflow across its surface, giving you every split-second advantage over your competition. Lycra at the front hits the wind first, and a textured mesh smooths air separation as you propel yourself forward. The shoe cover is secured with a full-length rear zipper that hides safely from the wind to hold everything confidently in place.
