I am between a 7.5 and an 8. I always order up a size in sneakers (meaning I order the 8). I could barely get my foot into this show.  I loosened the laces as much as possible, and managed to get the shoe on my foot, but I was so uncomfortable.  What a disappointment because the sneaker is cute (although a little cheap looking in person).  A leather version would be really nice.  Anyway, the shoes were so uncomfortable, I had to return them.
