First time I ordered a full size based on comments in a review. They were half size so I went back and got half a size bigger than my usual size. Ideal. If you don't have narrow feet, you can go up a half to full size with socks. Speaking of socks. They came with a FREE pair of walkers! good surprise See photo. Peds lie on my feet. It's really comfortable and cute. They have a flexible (not stiff) rubber outsole that adds a bit of extra cushioning as far as I can tell. I am enthusiastic about the design and comfort. I would definitely buy again.
