Castelli Aero Race MR Bike Shoe Covers Black/Fluro Yellow 2019

Four years in development and now in the 6th incarnation, it goes without saying these Castelli Aero Race Shoecovers are very special shoe covers. These are CFD computer modelled then tested in the wind tunnel to ensure the most aerodynamic design possible. If you’re chasing a PB, a gold medal or a Championship top step, these may help you find that extra second.

The on-bike aerodynamics dictate a closed heel area in order to offer the ultimate in aerodynamic advantages. This makes them very prone to wear off the bike. These covers really are a case of performance over practicality. Please be aware that these heels will wear quickly if you put your heel down or walk in them. To prolong the life of the shoe cover, remove the heel gripper on your shoe and always stop cleat down. Remove the covers immediately after the event. Wear your trainers to the top step of the podium!
