Note: Birkenstock shoes run large. We recommend purchasing one size smaller than your usual size for a regular width sandal. The Birkenstock Gizeh Birko-Flor toe sandal is a brand new addition to the Birkenstock collection. The Birkenstock Gizeh Birko-Flor toe sandal features an adjustable strap to fit all foot shapes. The cork and latex footbed conforms to the contours of the foot, helping to maintain proper posture and gait. Following biomechanical principles, it promotes blood circulation, provides support, and helps distribute weight.
