Fashion and functionality go well together with the Birkenstock Madrid sandal. The straps are made of top-quality and skin-friendly Birko-Flor with a soft felt lining. The anatomically shaped cork foot bed with a top layer of microfiber gives this sandal its comfort. For the production of this sandal no animal products are used. The vegan composition of the material is checked by independent laboratories. Because of the positioning of the adjustable strap on the foot bed the calves are trained with every step. The Birkenstock Madrid vegan pull-up anthracite is available in the width ‘normal’.
