These shoes run large.  I'm normally an 8 wide but I've ordered several pairs of these in a 71/2 instead. They're slightly snug in the toes but they don't go up and down.  I suppose I could have used those foam pads in the back for my regular size.  I have four pairs of these and have always purchased one half size smaller, but recently got the silver in a 7 1/2 and it's extremely small.
