Birko Flor® Uppers, Birkenstock’s Gizeh walks on the smarter side of the thong sandal. Probably the most comfortable sandal you’ll own, a contoured cork footbed conforms to the shape of your foot for unrivalled support and comfort, while a lightweight, grippy EVA sole keeps you steady. These mocha-brown slip-ons replace classic leather with synthetic Birko Flor® material that’s skin-friendly, hard-wearing and vegan.
