Funny story: I bought these in two sizes last summer and packed up the ones that didn’t fit to return. I was cleaning out my closet and found the entire box all taped complete with mailing label ready to go. I never sent them back! So I now have a gorgeous pair of never worn leather Birks! Here’s the official details: The BIRKENSTOCK Arizona, completely wrapped in leather, impresses with its elegant look. The exquisite footbed is fully covered with soft smooth leather, ensuring exceptional comfort and a more elevated, polished style. The upper is made from high-quality, soft natural leather.
