Birkenstock 40091 Madrid Birko-Flor Brown

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 favourite. The upper is made from the skin-friendly, hard-wearing synthetic material Birko-Flor in a sophisticated nubuck look which boasts a texture and colour that could almost be mistaken for real leather.
