I don't generally wear heels, so take with a grain of salt.

The shoe is very cute, and the heels are fairly low.  I purchased this after a long search for a cute, reasonably comfortable silver dress shoe.  The heels are angled funny and may slip if your foot doesn't land flat, so I had a little trouble walking.  Not a huge deal.  It's fairly comfortable to stand in, though it could have better padding.  I have a pretty low tolerance for these things, and I stood for almost 5 hours straight, although my feet did hurt quite a bit by the end.

As for the width, I have a normal width foot, but the normal width in store was a bit too narrow.  I got the wide online and now the width is fine but the slingback strap is too loose, and it feels like it's going to come off all the time.  I considered trying the 6 wide, but instead I'll just put in some gel pads, that should solve all my problems.

Still, would buy again.  Way better than all the alternatives I've seen.
