The BIRKENSTOCK Madrid is the oldest member of the family of models, making it a veritable classic. Launched as a “gymnastics sandal” half a century ago, this simple single-strap model has gone on to become a firm fashion favorite. This version comes with our popular Big Buckle and boasts a feminine floral print on the footbed. The upper is made from high-quality nubuck leather that boasts a natural, rustic appearance.
