I usually wear a 7.5 but when I received them, they were too big. Thankfully, I was able to exchange them for a smaller size. The shoes are very comfortable. The only thing that I found was that the back of the shoe is high on the heel and it did rub a bit on one foot. Other than that, the shoes are great. They're like a cross between a flat and a sneaker, and how could you ever go wrong with that combination.
