I purchased these in black for an upcoming trip to Europe, looking for something comfortable and casual that I could wear while on walking tours.  I was drawn by the perforated leather for breathability and the memory foam insole.  Unfotunately when they arrived I found the toe box to be rather small.  My toe hit against the front of the shoe.  I also have a narrower foot and these were just a bit wide so I didn't thing sizing up would be an option.  I ordered these in my normal size 8.5.  I would recommend sizing up a half size if you have a foot of normal width.
