The BIRKENSTOCK Madrid is a true classic that inspires the fashion world with its purist design. The popular sandal has been given a material update and is now available in a vegan version. It is completely free of animal components, which is controlled by independent testing laboratories. The upper material consists of the skin-friendly and durable synthetic material Birko-Flor in a noble nubuck look and thus looks confusingly similar to real leather in texture and color.
