The neoprene toe cover is a convenient accessory for riding when the weather is just starting to turn fresh the open design means that you can apply the cover and remove it very easily allowing climate control on longer rides the neoprene fabric stretches around the shoe and covers the front end of the shoe which is the most exposed area to the wind chill most cycle shoes have venting to allow hot air out on hot days the toe cover blocks these holes and adds a barrier to keep the feet warm
