I have very wide feet, so I did order 1/2 size larger than my usual size.  That being said, these are very comfortable, with nice padding on the sole.  The only problem I can see is that the back of the heel is very hard (there's an insert of some kind in there).  This helps the shoe hold its shape, and although it doesn't bother me at all, if you're sensitive to that sort of thing it might be a problem.
