The Birkenstock Unisex Arizona Birko-Flor Nubuck Sandals are a classic two-strap style sandal with an adjustable fit and a contoured cork footbed that conforms to the shape of your foot for a truly custom fit. Made of durable Birkibuc synthetic materials, this sandal features a nubuck leather-like texture, soft backing, and a lightweight EVA sole for cushioning and shock absorption. The deep heel cup and longitudinal and transverse arch supports provide added stability and comfort, while the flexible leather lining is gentle on the skin and provides a comfortable foot climate.
