The BIRKENSTOCK Gizeh is a genuine classic that combines optimum grip with minimalist, fashionable design. The Big Buckle version features a large, elegant pin buckle – a fantastic, striking eye-catcher on this otherwise understated sandal. The upper is made from high-quality nubuck leather that boasts a natural, rustic appearance. Size 38. US 7-7.5 (I believe closer to a 7.5 comfortably). Anatomically shaped cork-latex footbed Upper: nubuck leather Footbed lining: suede Details: thong style with an individually adjustable metal pin buckle “Made in Germany” NOTE: these were only worn a few times, mostly indoors. The foot bed footprint always appears somewhat darker when worn even a few times and shows that your toes are engaging with the "toe bar" in the front of the sandal, which is designed to aid in the natural rolling motion of the foot. While it does show darker, it is not from heavy wear. Please be sure to view all photos and let me know if you have any questions. Thank you for your interest!
