The Birkenstock Womens Buckley Nubuck Leather Old Rose is a semi-open moccasin-style clog that’s instantly recognizable as an authentic BIRKENSTOCK original thanks to its thick cork sole. The striking stitching catches the eye. The color-coordinated footbed rounds off the shoe’s look of sophistication. The upper is made from high-quality nubuck leather that boasts a natural, rustic appearance.
