This is a new and modern interpretation of the Birkenstock classic Madrid. This version features our popular Big Buckle made from a stainless synthetic material and makes an impression with its durability and minimalist design. Modelled on the cork sandal. it is made from the ultra-lightweight and highly flexible synthetic material EVA. The high-quality. odour-neutral EVA has been tested for harmful substances and combines numerous positive attributes: it is very light. highly elastic. shock-absorbent. water-resistant. and skin-friendly.
