These women’s Birkenstock ‘Arizona’ Slim Fit Sandals have an adjustable two-pin buckle, which can be used to tailor fit the shoe to the foot. The classic Birkenstock is usually bought on the large side, in order to allow for the natural rolling motion of the feet, so this is an important detail. These Birkenstock sandals are thinner in width than the classic design, but they feature a lot of the same signature details. With a synthetic upper and additional foot bed support for super comfortable wear, these shoes are perfect for walking. The state of the art Birko Flor upper gives the sandals an orthopaedic design. Upper: Synthetic. Lining: Suede. Sole: Rubber. Heel Height: 1 Inch
