9, S/M. I wasn't sure if it was the right size. They are SO HEAVY. But there is room in the sock so the tightness is really all around the foot. I'm getting used to them and they're great for a workout, but when I get home and sit down at my desk, they pinch my legs. I wear 9 (women's) shoes. I think the quality is very high and if you want some serious compression this is for you.
