I have always thought Crocs were the ugliest shoes I've ever seen, and I couldn't believe it when I found myself ordering them for my boyfriend, who was given doctor's orders to never be barefoot again. These are a great shoe for around-the-house wear; they slide on (but have a heel strap if you are into that sort of thing), and give a great deal of support. They don't seem to hold onto odor, and don't get too hot or too cold. He usually wears a size 14, and the size 15 fit him pretty well (so they run a bit small). My only complaint is that they seem to be comfortable enough that you start to think they look OK with that outfit... :-) I would definitely recommend these for people with foot and knee pain.
