These just arrived and I was nervous because of the reviews to order a size smaller.  I wear an 8 and ordered an 8.  Glad I did.  Though there is more room that most of my slip on shoes, a 7.5 would have been too small.  It is such a great "flat" look with tennis shoe support.  Exactly what I was looking for to go with my capris when I have a lot of walking to do.  I'm so glad I ordered (and in my own size).
