The BIRKENSTOCK Milano offers all of this thanks to its compact design with an ankle strap. 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 color. The upper is made from extra thick, oiled nubuck leather with an open-selvage finish.
