For many years, I wear as slippers only these Birkenstock Arizona. After a few years, although breaking the cork sole and rubber soles are totally expired, but until then the things are really good. I always take the soft nubuck leather, which is my favorite and is indestructible. Very good is also that you can choose between a narrow and a wide footbed. Why do I, despite the many praise only four stars? The color (basalt) I do not like really. I would have again to choose black.
