A thick, fleece shoe cover designed for riding in cold and windy conditions, the Castelli Narcisista Shoecover is the perfect addition to your winter wardrobe. The thick and fleecy portion of the Narcisista is Stratolight fabric. It's designed to provide superior insulation for your foot. Neoprene inserts also help to provide warmth and flexibility, while a plisse insert ensures a stretchy, foot hugging fit. Perhaps most importantly, after input from riders on the Garmin Cervelo professional cycling team, Castelli moved the Narcisista's zipper to the outside, making it harder for water to seep into your shoe and easier to adjust while riding. The Castelli Narcisista Shoecover comes in Black and features reflective detailing on the back of the heel to increase visibility in low light conditions you know, the kind of conditions you'll be riding in if you want to have any chance of winning races in March and April. They come in five sizes from Small through XX Large. Be sure to check the sizing chart to ensure proper fit.
