I don't know about these.... Im a 9.. I got a 10 to be safe because a lot of reviews said they run small and they still seem somewhat small .. not so small that I would return them but that they need to be maybe broken in a bit.  When the box arrived it was kinda bent and the colorful lines on the side are coming apart .... and I haven't even wore them yet!! I love the look of the shoe with all the colors but They are cheaply made. Kinda disappointed since Ive been eyeing them for a while. Hoping to at least get a few wears out of them over the summer.
