Leave nothing but footprints in Birkenstock's iconic thong sandal. The Gizeh features a flexible toe resin piece that combines with tear-resistant Birko-flor uppers, complete with ultra-comfortable felted backing. This fully adjustable synthetic strap resists water and stains, and won't stretch or fade. Wipes clean with mild soap and water.No break-in required. The classic footbed features suede and contoured arch and metatarsal support, a deep heel cup for optimum stability, and natural cork and jute materials that form to the foot over time. Wear them running errands, to the farmer's market, or to the beach.
