Single strap sandals from Birkenstock. The all-white 'Madrid' sandals are constructed with an adjustable, oiled nubuck leather strap upper and the label's trademark contoured cork and latex footbed. Set upon a shock absorbing EVA sole that offers both comfort and foot support. Birkenstocks are designed to fit slightly generously in order to perform the natural rolling motion of the foot without restrictions. This gives the feeling of walking barefoot. - R.R. Upper: Oiled Nubuck Leather. Lining: Suede. Sole: EVA Rubber.
