Familiarity: I've put it through the wringer
Fit: Runs small
These are one of the most comfortable shoes I have. Love love love them. They are very light weight… Size runs a bit small. So I suggest buying half /full size up. I normally wear a size 8.5-9, but from reading other reviews. I brought 9 1/2 and they fit perfectly.
