The Milano sandal guarantees good grip and due to the wide backstrap offers a more secure fit. A compact 2 strap upper gives maximum adjustability. The contoured cork foot-bed conforms to the shape of your foot. The upper is made from the skin-friendly, hard-wearing synthetic material Birko-Flor: a high-quality material which is comfortable & gentle on the skin, while also being very durable. Birkenstock sandals fit true to size.
