This robust Birkenstock Madrid sandal with adjustable strap above the instep is made of the skin friendly material called Birko-Flor and comes in the colour navy. The raw nubuck-look is obtained by a special finish. The lining of the strap is made of a soft felt which makes this sandal extra comfortable. The original cork foot bed with a top layer of suede makes this sandal a real summer item. The Birkenstock Madrid nubuck navy is available in the width ‘normal’.
