The Crossmax Thermo shoe cover will protect you from cold, rain and ploughing through puddles.
Warm Shell ST fabric, which is insulated and water resistant.
It will also keep you protected from scrapes and scratches with extra-tough Hypalon material on the heel and toe, and high-abrasion protection from Scuff Guard+.
Plus it is highly reflective so people can see you through the gloom and the spray.
Last but not least, Mavic have given it a specific MTB fit, with a strap to adjust it precisely to the style of shoe you’re wearing.
