These shoes were far more beautiful in person than they were online.  I ordered my usual size (7).  They fit, but pinch just a little at the toes.  Since they are leather, I expect they will stretch with time.  I have found that leather stretches out about a half size.  If you have normal-to-narrow feet, buy your usual size and walk around in them at home for several hours/days before wearing them out of the house.  I found these were relatively comfortable.  I put ball-of-foot inserts in, and they are very comfortable heels.  I have worn them several times and have not had problems with the crystals falling out.  I love these shoes!
