I've been looking into getting one of these shoes, but don't know which to get. I have been struggling with knee pain and have seen that these could both help. I don't know what size to get though. I wear a size 11US and have narrow and flat feet. I've seen that I should go up half a size, down half a size, and keep my normal size. I need help. What do I do?
