The GripGrab Race Thermo X Shoe Covers will fast become your best companion when riding cross-country MTB and cyclocross in the winter months. Made from insulating neoprene, they shield your feet from mud, spray and wind; and GripGrab's zipper-less design provides a smooth junction with your calf muscles: to reduce irritation, improve durability, and increase comfort. These overshoes also feature IntelliSeal – an ingenious technology that greatly enhances the durability and water resistance thanks to the coated seams at the bottom of the shoe covers. The RaceThermo X model is specifically designed to accommodate the lugs on MTB SPD shoes through its open sole design and Kevlar reinforced base. If you have to dismount for an obstacle when riding off-road, you can still walk and run with these shoe covers. The sole also features a small robust Nylon strap that sits tight behind the front studs keeping the overshoe in place. These overshoes are NOT compatible with wide trekking or trail/platform shoes, even if those feature SPD cleats. Ride in all weather, both on and off-road. These are unisex overshoes for men and women. GripGrab Tip: Combine these shoe covers with a pair of warm socks and give them a damp wipe with a clean cloth after your ride.
