The back cuts into my heel badly and did not improve after a day. I ended up walking on my tip-toes for the day to avoid the pain. The length and width sizing were my normal 8.5. The structure on the side seems very poor and kind of collapses on my foot, leading to a weird slouchy look that is not attractive. Overall, they do not fit like a glove as I was expecting. This could be due to the shape of my foot, but I have not had issues like this before. Unfortunately, because I wore them all day (inside), the soles are a bit darkened so I doubt I can return them.
