    • Vibram FiveFingers footwear is designed around the foot's measurement in inches. There is no real 100% translation between your US size and FiveFingers size. In order to find the right size, please measure both feet from heel to tip of longest toe with a ruler in inches. Take the longest measurement of your longest foot and refer to the Vibram FiveFingers men's or women's size chart to find your shoe size.
