From the Manufacturer
This is the real deal. Cork, leather, a buckle or two: these are the simple ideas that have made feet happy for over two hundred years, and that's the original Birkenstock. These shoes are made in Germany since 1774. No smoke, no mirrors, and no gizmos are needed. You walk, the shoe molds to your foot. The shape of the Original Birkenstock Footbed enables body weight to be distributed evenly over the whole foot, providing it with optimal support.
