The BIRKENSTOCK Gizeh is a stylish all-rounder: extremely versatile yet unbelievably comfortable. Its design and function have remained unchanged since it was introduced in 1983, and the classic thong sandal stands out for its timeless style. Thanks to the buckle, the strap can be individually adjusted to the weareris feet. The anatomically shaped thong provides additional support for the toes and guides them back to their natural position. Birkibuc Upper / Classic Footbed - Suede LinedBirkibuc or Birko-Flor Nubuck is Birkenstock's trade marked synthetic nubuck leather. Slightly porous with a matte finish and compressed felt backing. The essence of all our shoe models is the original BIRKENSTOCK footbed, which is inspired by the natural imprint of a foot in the sand and feels just like walking barefoot. Its anatomical shape ideally supports the natural walking action of your foot. Your feet, joints and back are protected. At the same time, your foot and leg muscles are exercised, and your health and well-being benefit as a result.
