The Arizona sandal from BIRKENSTOCK is a classic, combining a great fit with a timeless design. The upper is made of skin-friendly and durable Birko-Flor® with an elegant patent coating. It features an anatomical cork and latex footbed, a suede upper sole, and an EVA outsole. Details include a strap with two individually adjustable metal buckles and it is "Made in Germany". The Birko-Flor® lacquer is made of hygienic, easy-care PVC plastic with a soft, thermoactive non-woven layer bonded to the inside and coated with a varnish. This high-quality material is skin-friendly and provides a very comfortable fit. The insole is hypoallergenic and flexible leather, gently hugging the foot and adapting to its contours. The open-pore surface is particularly thermoactive, keeping feet at a pleasant temperature even during intense physical activity. Cork, a renewable raw material extracted from the bark of the cork oak tree, is used for the footbed.
