I am also selling this on other platforms, so I will prioritize the first sale. These are original engineer boots from kindsupply_co in Vietnam. Not available in Japan. The retail price is about 100,000 yen. Size: US 6.5 (24.5cm) My personal size impression: Compared to Red Wing, they feel about a half to one size larger. These are engineer boots made of natural nubuck leather. They have been worn quite a bit and are showing signs of aging. There are many stains and scratches. They feel light on the feet for engineer boots. The heels have been replaced once, and at that time the leather stack was removed, resulting in a low-heel customization.
