Details, from Birkenstock: An icon since 1963, the Madrid redefined sandals with its contoured footbed and a single, sophisticated strap. A gleaming big buckle makes a statement on oiled leather, designed to age beautifully with wear for a unique, well-traveled patina. 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 • Smooth leather footbed lining • EVA sole is flexible and lightweight • Adjustable strap with oversized metal pin buckle Made in Germany. 🔎 CONDITION REPORT > Great—branding faded on the insole & regular wear throughout but thoroughly cleaned and with no major flaws deeming them unwearable.
