The Birkenstock Madrid is a true classic that captivates the fashion world with its minimalist design. The Big Buckle variant features a large, elegant pin buckle – a great, striking highlight on an otherwise simple sandal. The top layer of the semi-exquisite footbed is covered with soft smooth leather, color-coordinated with the shoe. The upper material is made of particularly thick, oiled nubuck leather, which has been processed with raw edges.
