The BIRKENSTOCK Arizona is a genuine classic that has been delighting both men and women with its timeless design for decades. Modeled on the cork original, this sandal is made from ultra lightweight and highly flexible EVA. This high-quality, odor-neutral synthetic material which has been tested for harmful substances is shock-absorbent, waterproof, and skin-friendly. It is therefore perfect for wearing on the beach, in the garden, or in wellness and spa areas. 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.
