I sized down 1/2 size, and it almost worked out. The 6 1/2 shoe length was better than the 7,  in terms of my foot sitting correctly on the sole, but my toes rub on the top/ end of the shoe. Made the toes feel bruised after a few hours of that nonsense. It seems to be caused by a shallow toe box. The shoe is cute for a flat- a little stiff on the bottom- but more comfortable than a regular flat. I find my arches ached after wearing them for a work day; not much support there. I will wear them, but not often. I buy lots of shoes; I bought 4 pair this month, and compared to other brands I don't get the hype.
