Birkenstock Ramses BS Stone Regular Fit SIZE: (Men’s 8 US ) (Women’s 10 US) COLOR: Dark Brown The BIRKENSTOCK Ramses is the men’s version of the popular Gizeh thong sandal. The slightly wider strap lends this sandal a strikingly masculine appearance. The upper is made from the skin-friendly, hard-wearing synthetic material Birko-Flor® in a sophisticated nubuck look which boasts a texture and color that could almost be mistaken for real leather. Anatomically shaped cork-latex footbed Upper: Birko-Flor® nubuck Footbed lining: suede Sole: EVA Details: thong with an individually adjustable metal pin buckle “Made in Germany” Upper material: Birko-Flor® Nubuck The look and feel of Birko-Flor® Nubuck is an almost perfect imitation of authentic nubuck leather. Insole: Natural leather Natural leather can be recognized by its untreated surface. BIRKENSTOCK purposely does not treat surface grains and other characteristic features. BIRKENSTOCK uses sturdy leather with a thickness of 2.8 to 3.2 millimeters as upper material. Footbed material: Cork Cork is a sustainable material extracted from the bark layer of the cork oak. This natural product is insulating and offers very good cushioning. Outsole: EVA EVA (ethylene vinyl acetate) is a high-quality, very light, elastic material with extremely good cushioning. As a result, it smooths out slight irregularities in the floor and ensures that every step is softly cushioned.
