I wear a borderline medium/wide width and ordered the wide.  The toe box is perfect, no squished toes but still cradled, not sloppy.  The sides are a little on the wide side and it just keeps getting wider.  My heel narrows, not widens; doesn't everyone's?  The dealbreaker is that the back of the heel bumps out into a point for some reason; so much so, that I can stick a whole finger or two in the gap.  My toes are hitting at just the right place in the toe box so I don't dare order down 1/2 a size in length or it'd be too short.  It's a shame because the shoe looks great, very classy and has a perfect, thick, mid-high heel, ideal to wear with skirts at work.  If I were willing to pile-in a bunch of those heel-grabber peel-n-stick inserts I might try it, but I think it would be a losing effort and just too irritating in the process.  I'll stick with my Clarks model Levee Bank pump, it fits correctly without this goofy heel issue.
