I went by the sizing chart provided (and double-checked the sizing on the Vibram website) and ordered accordingly. About 1 size too big...and the sizing for the 41 on here says 9-9.5 yet on the box it says 41 and 8.5-9. The area near the ankle is also cut a bit high...was rubbing with just trying them on. Cute and I wanted to love them but not so much...
