Mavic's Knit Shoe Covers were made to protect your brand new, limited-edition road shoes from the dangers of riding on gritty early-season roads, and they also offer some thermal protection in case the air is still holding onto winter. Knit from moisture-wicking, fast-drying Meryl Skinlife fabric, the shoe covers won't trap heat and are easy to pull on over your shoes, plus, they include a cleat opening so you can keep them on to walk around post-ride.
