Review on RockBros Thermal Shoe Covers for Cycling Shoes - Windproof Half Toe Covers, Water-Resistant for Mountain and Road Biking - Black by Dustin Keller

Update: After a few rides to/from work in 10-30 degrees I can find that these overshoes don't want to stay on my shoes (size 11.5) and don't add much warmth. It was literally pointless to buy them. For the most part, they're well made and worth the money, except for one thing: Velcro. It's ridiculously small and doesn't close. i cut it off The elastic band keeps the case perfectly in place. The problem is that the rubber band is not durable and without protection (e.g. a band of the right length) I don't think it will last very long. Good news? They are inexpensive.
