The Birkenstock Arizona is a genuine classic that has been delighting both men and women for decades. This simple sandal with two straps offers a timeless design and has long held a cult status thanks to its comfort factor. The upper is made from the skin-friendly, hard-wearing synthetic material Birko-Flor®.  Most people will own a pair of Birko-Flor Birks thinking they are crafted from real leather (it's that good) but really they are a synthetic alternative. The two buckle adjustment helps to fine tune the fit whilst the regular fitting footbed offers superior comfort for the day ahead with its contoured cork footbed with pronounced arch support and deep heel cup. Birko-Flor® is a skin-friendly, tear-resistant and easy-to-care-for synthetic material which is exclusively used by Birkenstock.  It features a soft, inner felt backing with faux-leather outer.
