I normally wear between a 9.5 and a 10 in women's shoes. I ordered a 9.5 and they were a little too big. I didnt really like the black and white one i picked out, it looks better in the picture. ( the other colors were cooler but i needed a black a white shoe for work). The shoe size calculator was very close to being spot on, with out the shoe calculator/comparer I would have ordered a 10 and then the shoes would have been way too big.  It is a good buy for the price, if i had to do anything different I would have ordered a different color.
