The BIRKENSTOCK Arizona is a true classic. Modelled on the cork sandal, it is made from ultra-light and highly flexible EVA. The high-quality, odour-neutral EVA has been tested for harmful substances and combines numerous positive attributes. It’s waterproof, ultra-lightweight, washable and therefore extremely easy to care for. EVA (ethylene vinyl acetate) is a high-quality, very light, elastic material with very good cushioning. As a result, it smooths out slight irregularities in the floor and ensures that every step is softly cushioned.
