You've come a long way since your first pair of Birkenstock Arizonas--now you can enjoy that familiar comfort in a more refined, professional look. You'll get the same supportive footbed, but it's completely covered in leather so there is no exposed cork. The deep heel cup provides stability and cushion while walking. The leather lining the footbed has tiny perforations for breathability. Lightweight EVA soles are flexible, durable and provide some cushioning. Resoleable.
