***runs small, fits like 36.5EU or 6.5US imo- please see measurements! The original laces were blue and didn't match at all so I switched them out for new heavy duty black lock laces ($10 value) they are flexible and ultra comfortable, designed for a true barefoot feel. they will allow your toes to spread out naturally and allow you to use your foot muscles naturally without artificial support. Smoke free, pet-friendly home.
