These Birkenstock Arizona Birkibuc Narrow Fit Sandals combine classic style with ultimate comfort for a laid-back look. The Birkibuc synthetic leather upper is durable and provides a leather-like finish. The contoured cork-latex footbed provides custom support with wear, while the suede footbed lining ensures comfort. An EVA sole is flexible and lightweight, and the two adjustable straps with metal pin buckles provide a secure fit. Additionally, the deep heel cup cradles the heel and keeps cushioning under the heel bone, and the arch support promotes stability and proper foot alignment. There is also a raised toe bar to stimulate circulation and a roomy toe box for better balance and alignment.
