Birkenstock Birkenstock Arizona Black Size: 26cm (40) Purchased about 8 years ago. Worn about 3 times, but the adhesive on the side is peeling off, so it's priced low. (There's no problem with wearing them, but durability is unknown.) I'm selling them because they don't fit my feet and I haven't worn them much. I think the metal parts are relatively clean. Depending on the shape of your foot, they should fit up to 26-27cm. Please understand that these are used items and have been stored at home by a private individual before purchasing.
