Purchased in Hawaii 6 years ago and worn twice for testing. I remember being careful not to wear down the soles. Afterwards, they were put back in the box and stored in the shoe cabinet. Retail price: 15,400 yen Birko-Flor Nubuck - Color: Stone It's Birko-Flor Nubuck, not just Birko-Flor. This color is discontinued in Japan. While the current official website has Gizeh sandals in Birko-Flor Nubuck Stone, the current Japanese official website only lists Ramses sandals in Birko-Flor (polyvinyl chloride), and there is no mention of Birko-Flor Nubuck (a synthetic material with the texture of genuine nubuck leather) in the Stone color. It is currently not sold domestically. The soles show no wear and are in very good condition. Please check the photos. Size 39, which is 25.0cm. - Brand: Birkenstock - Color: Gray - Style: Sandals - Sole Material: Rubber Thank you for looking.
