Full disclaimer - I own a couple of Nine West pumps and they always seem to be a little too narrow for my foot.  I usually wear a standard 7 and don't have issues with the width, but in my experience I think Nine West pumps probably fit best on a slim foot.  I wore these to a conference so the only walking I was doing was really from one room to the next and still by the end of the day my feet were miserable in these shoes.  My poor pinkie toe was bright red!  I thought maybe they just needed to be broken in, but even after a couple of wears they still hurt my feet if I wear them for more than a couple of hours.<br /><br />Nine West sandals always fit me well, so I guess I just have to give up on all of their cute pumps and be happy with their other offerings.
