This shoe just looks small.  But I ordered up a whole size and even then they fit snug.  I wore them around in the house for a couple of hours and had no ill effects.  They loosened up and fit my arch well.  I got black and they make my feet look really small.  I ordered a larger size based on other reviews...thanks, the input is valuable.  Comfortable and cute, order up.  I'm thinking red now!
