I had bought these shoes for my mother who wears a half size to a full size bigger than I do.  While she could get her foot in, it was not perfectly comfortable, so she gave them to me.  It is a comfortable fit for me.

I have noticed though that when you walk, the heel padding seems to sink and this tends to cause your heel to rub against the back. I think this is probably best worn with socks to prevent blisters.
