My mother purchased these sandals and doesn't like them, so I am selling them for her. The best I can tell is they are Franca style Birkenstock in the color of Oiled Leather Black. They have been worn a few times. Size is EU 40 or American 9-9.5 with the Medium/Narrow Foot Sign on the footbed. They would have been purchased from a reputable shoe store, so I am certain they are authentic. Price on Birkenstock.com is $130. Smoke free, cat friendly home. Crisscross straps with the comfort to match. The Franca sandal is refashioned in oiled leather to only get better with wear, giving you a heritage, well-traveled patina as soon as it comes out of the box. With an original contoured footbed for support, it'll feel uniquely yours wherever you take it. Contoured cork-latex footbed creates custom support with wear Oiled leather upper gives each pair a unique finish Suede footbed lining helps keep you comfortable Flexible EVA sole Three adjustable straps with metal pin buckles Made in Germany
