It took me a couple of days to break them down. To be quite honest it was a little painful to wear them the first day, but I have the same problem with pretty much every new shoe I buy. Originally I ordered a 6 1/2 but I had to return them because they were way to big, I got half a size smaller and they fit a little tight but I wore them with thick socks for a day or two and that did the trick. Besides that, I love them. I wear them all the time and they are super comfy!
