I had to return them as the back was very stiff against my ankle. They were true to size. Maybe you can find something to stick something up your butt so it doesn't hurt, maybe that would be better? I do not know.

I bought these shoes because I saw that they were on sale with a 50% discount. I was really in need of shoes and I have to say they have to be the most comfortable shoes I have ever bought. I don't feel tired at all when I stand or walk for a long time. I will definitely buy them again, even at the regular price... I actually bought 2 more pairs.
