The BIRKENSTOCK Arizona is a genuine classic that has been delighting both men and women with its timeless design for decades. The color-coordinated buckles with a textile feel and a matte design are additional eye-catchers. With its additional foam layer, the soft footbed offers extra comfort and pampers feetall day long. The upper is made from soft suede. Suede is a split leather with a napped finish. It has a velvety surface and is very soft to the touch. It also boasts a high moisture absorption capacity. Suede is softer and more flexible by nature and does not have the same stability as smooth leather. The stability of suede also varies from hide to hide. This does not constitute a material or production defect.
