The Arizona, a classic BIRKENSTOCK with a timeless design, has been pleasing men and women for decades. This Big Buckle version features an elegant, large buckle that adds a touch of flair. The semi-exquisite outsole is covered in smooth, color-matched leather, and the upper is crafted from particularly thick, oiled nubuck leather with raw edges. Features an anatomical cork and latex footbed, two adjustable straps with metal buckles, and a color-matched footbed. Made in Germany. The greased leather used has an untreated surface, with BIRKENSTOCK choosing not to treat veins and other characteristic features. For the upper, BIRKENSTOCK uses leather of 2.8 to 3.2 millimeters thickness. The insole is made of soft piumato leather, and the cork and latex footbed offers a premium look, fully lined with soft piumato leather. Cork is a renewable raw material.
