The BIRKENSTOCK Madrid model is the oldest member of the family, which has established it as a true classic. Launched half a century ago as a gym sandal, the purist single-strap model has long since become a stylish accessory. The outstanding chromaticism of the sole achieves a striking contrast with the upper material, which completes the image. The upper material is made of Birko-Flor®, a durable and skin-friendly synthetic material, with a lacquer coating. Anatomical cork-latex insole Upper material: Birko-Flor® with lacquer coating Insole upper layer: suede Sole: EVA Details: a strap with a metal pin buckle and individual adjustment Made in Germany
