I tried these shoes on in a carpeted room.  I tried to walk in them.  Imagine a person in shoes trying to walk on ice, and you'll be able to imagine what I looked like.  I literally couldn't move, my feet were sliding on the carpet so much.  Awesome.  That is easily fixed by adding nonslip grip tape to the soles (though I don't think I should have to, at this price).  The other issue I had with these shoes was the back of the shoe slipping off my heel as I tried to walk.  (No, I did not order the wrong size).  A person's ability to walk in 4 inch heels is dependent upon how well the shoe stays on the back of your foot.  You need that leverage in order to walk.  If the shoe slips off the back of your foot, you are doomed - and barefoot.

Needless to say, these silly things were returned.  Shame, because gray suede pumps are apparently not easy to come by.
