Run very small!
I would order at least a half size larger but you run into an issue with the ankle strap size. Not sure if it was just this shoe or all the leather shoes in this style, but the ankle strap was very big while the rest of the shoe was very tight. It is a beautiful shoe though so if you can find the right fit, I would recommend it.
