First off let me explain, I am a male and my foot size in shoes is 9.5-10 which for some reason is a women size for Vibram. Doesnt make sense to me.

Anyways I was let down at first because they were very tight and painful. But i sucked it up and now they fit pretty well but i could have gone up one more size. They are worth the money and I enjoy wearing them, and I do not run, I only work out in them. I even wear them when I work.

all in all a great product but the whole sizing thing can be tricky
