Castelli Aero Race Shoe Covers MR

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.
