The Birkenstock Madrid is a genuine classic that delights the world of fashion with its minimalist design. The Big Buckle version features a large, elegant pin buckle – a fantastic, striking eye-catcher on this otherwise understated sandal. The lining of the semi-exquisite footbed is covered with soft smooth leather and matches the shoe in colour. The upper is made from extra thick, oiled nubuck leather with an open-selvage finish.
