The Birkenstock Arizona Birkibuc Narrow Fit Sandals are a classic and comfortable shoe. The Birkibuc synthetic leather upper gives it a durable and leather-like finish. Its contoured cork-latex footbed provides custom support with wear while the suede footbed lining helps keep you comfortable. It features an EVA sole which is lightweight and flexible and two adjustable straps with metal pin buckles. The deep heel cup cradles the heel and keeps your natural cushioning right under the heel bone, while the longitudinal and transverse arch support run along the sides of the footbed and through the middle respectively, providing stability with each step. The raised toe bar encourages the natural gripping motion of your feet, exercise the legs and stimulates circulation, while the roomy toe box allows the toes to move more naturally, promoting better balance and correct foot alignment.
