"The legendary two-strap design from BIRKENSTOCK - the Arizona. Modeled on the cork original, this sandal is made from ultra lightweight and highly flexible EVA. These sandals are shock absorbing, waterproof, and skin-friendly. Wear them at the beach, in the garden, or around the gym and after workouts. It's the perfect addition to your classic BIRKENSTOCK sandals." -Birkenstock USA
