Gizeh style thong sandals by Betula...licensed by Birkenstock. Navy blue. Not real leather. Great sandals but just a bit too small and I finally bought a size up. In good condition. Size 37 which is generally perceived as a 6.5. However, the footbed say is " 37 L(adies) 6" please know your European size. "Birkenstock has made sub-collections of its sandals, including Betula, Papillio, and Footprints. These brands are all part of the Birkenstock family, and share the same contoured, natural cork and latex footbed design. The only difference tends to be the material and style chosen for the uppers."
