Sadness prevails. I bought these cause I am traveling soon and it will involve a lot of walking. These seem to be specifically designed for that, yet the back cut into my heel so badly that I thought I was being punished for a past life societal infraction. I am a size 9, ordered a size 9, and they ran about a half size too big. The bottom is cushy for sure, but they were brutally uncomfortable and had to return.
