I usually wear 24cm sneakers. It fits perfectly when I wear two pairs of socks. Size: US 6 1/2. According to my research, this corresponds to a Japanese size of 24.5cm. I purchased these at ABC Mart 20 years ago for touring. I used them for about a year initially, and then I've applied mink oil once a year and stored them in a well-ventilated place away from direct sunlight. There are many small scratches. I would appreciate it if you could refrain from making claims after purchase, such as damage not mentioned in the description. Please refer to the images, and don't hesitate to ask any questions or express any concerns, no matter how small, before purchasing. Thank you. - Brand: Red Wing Shoes - Color: Black Red Wing Leather shoes Leather Genuine leather
