Review on Shiwely Winter Cycling Shoe Covers - Thermal, Water Resistant, Windproof Bicycle Overshoes for Men and Women by Nathan Kumar

I gave these cases 3 stars because I haven't wet them yet to see if they are really waterproof. They don't get 5 stars because they aren't warm. NOT! I bought these to replace my Specialized shoe covers. They are warm because they have insulation inside. They have no insulation at all. They offer almost no extra warmth to your feet. I rode a bike today. It was 50 degrees. (Not even that cold) and my feet got a little cold. Not a big investment so I'll keep them to myself, but I'll buy overshoes with better thermal insulation.
