These are the perfect solution to sweaty toes inside my favorite leather sledge slip-ons from Naturalizer. They are so comfortable, but they don't breath at all. So when I slip my feet out, as I like to do because my feet get hot, they can smell bad. Well, that's not OK. This product is the sock those shoes require -- hidden so as not to spoil the halfsies look -- but present and absorbent and totally cute. I counted off one star because I have huge feet, a womens' size 12 US, and I had to scrunch them down a little so they would not show under my shoes. For a fuller slip-on shoe they would be perfect, but I thought they were "toe socks". Just be warned. Otherwise, awesome product.
