These women's Birkenstock 'Arizona' Sandals feature a comfortable double strap upper, which can be adjusted to fit the foot. The signature Birkenstock cork and latex base is included, and has remained almost unchanged since its inception in 1964. This is the trademark feature of the brand, and delivers a shoe that keeps the wearer happy and secure all day. They are founded upon a specially designed shock absorbent EVA sole, for extra support. The classic Birkenstock is supposed to be bought on the large size, in order to accommodate the natural rolling movements of the foot. The strap can be adjusted to fit, if the sandal feels overly generous. Upper: Birko-Flor®. Lining: Suede. Sole: EVA. Heel Height: 1 Inch
