These run large. I'm a 37 which is an equivalent to 6 /6.5. I normally wear an 8 American size. Birkenstocks are a great shoes. If you've never had a pair you need to know that you need to give it some time for your foot to mold into the shoe so it will be hard and maybe even a little painful at the beginning. However when your foot is molded in, you'll never want to wear any other sandal. It literally feels like you're not wearing shoes at all. I have bunions and flat feet and these work great. This particular style is cute enough to wear with a summer dress or any cute outfit
