Great shoes! I have narrow feet and mostly wear 9.5 D(M) Adidas shoes. They were a little bigger than I expected. I bought two pairs, one from Amazon, all white, size 9.5, and grey/blue, size 9, at a local sporting goods store. The latter fits better. The first one is a bit big and terrible because of the color. Don't buy it all white, it will get dirty too quickly. Half a size smaller worked for me.
