I really like the style of this shoe, but unfortunately the size seemed to run a bit small.  I wear a 9.5 and have somewhat wide feet, but the flats only fit with super thin stockings or none at all.  I get the feeling they would stretch a little, but only after a blister.  I have another pair of Rocket Dog flats in the same size that I adore so I'm disappointed these didn't fit as well.
