Highbridge International, a well-known Japanese shoe importer. This is a monkey boot (lineman boot) from their original brand, "Royal Gorge Bridge." Retail price: 63,800 yen (tax included) Reference ⬇️ http://bhc.shop-pro.jp/?pid=122759216 【Materials】 ① Upper: Chromexcel from the American Horween Leather Company, famous for Alden's cordovan. I believe this is a very good quality Chromexcel. It's very thick. The color is black, but it has a "brown core." The tongue has some brown core showing where it has rubbed against the hardware. ② Sole: Rubber sole made by mixing natural rubber and cork. Made in a factory that manufactures F1 tires, it is elastic, flexible, and durable. ③ Lining: High-quality leather 【Size】① Marked size 43, fits like a 28cm size. 【Country of Manufacture】Made in Italy. Made in an Italian workshop that OEM produces shoes for maison brands. 【Construction】Blake Rapid construction. The outsole is sewn onto the midsole, which is attached using the McKay method. Sole replacement is possible, just like with the Goodyear welt construction, and it is also highly flexible. I have worn these less than 10 times since I bought them new. I have many shoes, so the rotation interval is long, and I only wear boots in the winter. The condition is also clean, but there are small scratches. This brand is no longer in production, but I think you will be amazed by the overwhelming quality.
