Shoes almost never fit me in regular sizes- but the regular width fit me in these- which means they are wide.  If you have a narrow foot, these might not fit.  I loved my first pair so much I ordered 2 more right away.  I get a lot of compliments on these (I bought the yellow ones).  I don't know why they fit so well- I've got a size 10.5/11 wide foot with a small heel- but they fit great.  They kind of conform to my foot and I can wear these all day long.  They're light so they make great travel shoes.
