Birkenstock Birkenstock Arizona White 26cm (40) Purchased several years ago and worn with care, but I'm selling them because I haven't worn them much lately. I've regularly dried them in the shade and taken care of them. There's little dirt on the metal parts. Depending on the shape of your foot, they should fit sizes 26-27cm. Please understand that these are used items and have been stored at home by a private individual before purchasing! Thank you for looking.
