An outdoor staple for fashion and comfort, the Arizona Birko-Flor Nubuck Sandals feature Birkenstock's classic two-strap design, adjustable and able to tailor to the specific shape of your feet. With a premium nubuck leather lining, the sandals are also tough enough for heading out to the hills or exploring rugged coastlines and gentle against the skin, they won't irritate as you walk. The open-pored, breathable surface fabric also creates the perfect foot climate when undertaking physical activity, keeping your feet fresh and comfortable. With an original anatomically shaped footbed at the heart of every Birkenstock sandal, comfort is guaranteed. The deep heel cup cradles the heel for natural cushioning while a longitudinal arch support runs along the sides for added stability with each step. In the toe area, the raised toe bar also encourages the natural gripping motion of the feet, making the sandal ideal for prolonged walking. Sustainability Birkenstock constantly works to improve production processes, products, packaging and logistics. Thanks to the durability of its products, most are sustainable by nature as a high proportion of the natural materials that they use are from sustainable sources, cork, natural latex, jute, leather, wool felt, copper and brass are among these. All raw materials are also hand-picked and sourced sustainably and - as far as nature allows - are all from in Europe.
