I have a pair of these shoes in black and they are comfortable, so I ordered the navy ones online. I typically wear a wide width, but in this style, wide was too loose in the heel so I bought medium. This navy pair appears to run a bit shorter and more narrow than the black pair. However, they are stretching out with wear. The memory foam soles are very comfortable, which is what sold me on these shoes. I need a lot of cushioning on the balls of my feet, and these are wonderful.
