First of all, let me say that I really, really wanted to like these shoes.  The blue green pink combination is great.  I ordered a 6, my usual size, but they were way too small and very tight across the base of my toes.  So I exchanged for a 6 1/2.  Better, but still uncomfortably tight across the base of my toes.  This is right where the tongue is sewn into the shoe.  The insert in the shoe is absolutely worthless.  It is flimsy and does not give any support to the arches.  I changed it out for some custom orthotics that I already had, and they didn't work in the shoe either.  I wore the shoes around the house for a couple of hours and finally gave up because the shoes hurt my feet.
