The Birkenstock Arizona sandals have been a symbol of timeless design and legendary comfort since 1973. The Big Buckle model features large, spectacular buckles that add a luxurious touch to the familiar design. The upper is made of oiled cognac-colored nubuck leather, which develops a unique patina over time. The anatomical cork-latex footbed adapts to the foot and provides personalized support. The sole is made of flexible, lightweight EVA, which provides cushioning with every step.
