Castelli Aero Race shoecover 2025

For the days when you just want to keep the wind and rain out without any extra bulk. The thin, stretchy fabric forms to the shoe for a perfect, aero fit while blocking the wind and wet.

Less is more
Sometimes less is more. Professionals asked for a shoe cover that would be sufficient to keep out the wind and as much rain as possible without bulk or extra weight. Castelli has eliminated all the superfluous while still making an accessory that works. The fabric stretches to fit your shoe and blocks wind and moisture. A silicone non-slip inside the top of the shoe cover prevents water from getting inside while keeping it in place, and a long zip makes it easy to slip on and off. A high-strength fabric has also been added to the lower part of the shoe cover. It is an aerodynamic shoe cover that blocks wind and moisture.
