FAQ

Are these compatible with mountain bike shoes?

The Diluvio UL 2 is optimized for road and gravel shoes with two- or three-bolt cleat systems. Fit on MTB shoes with recessed cleats may vary.

How do I size these?

Castelli shoe covers generally match your cycling shoe size. If you are between sizes, size up for a better fit over thicker winter socks.

Can I use these in temperatures below freezing?

The Diluvio UL 2 is designed for wet-weather protection in mild to cool conditions. For freezing temperatures, consider a thicker insulated shoe cover with added thermal lining.

Best For

Riders who want lightweight, packable wet-weather coverage without the weight penalty of a thermal shoe cover. A go-to for spring and fall rainy rides where protection matters but warmth is secondary.
