I usually wear a 7 1/2 wide in most shoes.  I ordered the 7.5 c/d and it was tight (box was labeled 7 1/2 W fyi).  I have a very narrow heel and wide ball of the foot.  This shoe is a very straight design.  Very pretty and so soft on the feet, but the toe box runs narrow.  I am going to try again and exchange it for the 8 c/d.

You would have to add that if you have a high arch like mine.
