I wish they still carried these shoes. If you love them you need to buy up what you can now. I had a hard time finding any and unfortunately could only find two styles in my size from any seller. They are so comfortable, true to size and have the elastic piece to expand a little should you need it. My foot is in between a wide and a medium and they do stretch to accommodate both sizes. My daughter just wears a straight 8 and they fit her fine, too. All styles have seemed to fit about the same. This one was a little tighter to begin with but they do stretch out after wearing them a bit. As far as washing them, I don't know how they would fare. I have some that I bought 4 years ago that I still wear. The soles are kind of wore down the but uppers have stayed intact with no tears and no separation from the soles. They are almost like wearing slippers, very lightweight and just plain comfortable. They look cute with jeans, capris and shorts. Like i said, if you love these, stock up. You won't find them when these are all gone.
