Birkenstock Footwear is manufactured using a European size measurement. This system uses whole sizes only because the increments, from one size to the next, are only about 1/4 inch. The quickest way to figure out your Birkenstock European size would be to add: 30 to your American size for women. 33 to your American size for men. 17 to your American size for kids. Example: If you wear a ladies 8, add 30. Your Birkenstock size should be 38. The catalog chart doesn't always agree, but we have found these numbers to work best. Many styles, like the Barbados, Memphis, Oklahoma, Kentucky, run shorter, so 90% of the time you're going to need to go up a size.
