These are Red Wing engineer boots. They haven't been used much, as they were stored at home for a long time after purchase. The size marking is missing, so the exact US size and cm size are unknown. For reference, the outsole length is approximately 28.5cm. Please check the actual size and consider accordingly. For reference, a family member who usually wears 27cm shoes tried them on, but their ankles were too tight, and they couldn't get their feet in. Please note that the fit around the ankles and insteps varies from person to person, so this is just for reference. Currently, they can be worn without any problems, but as they are long-term storage items, there is a possibility of aging deterioration, such as the adhesive parts (soles, etc.) coming off, depending on future use and environment. These are used and long-term storage items, so please only consider purchasing if you are willing to consider maintenance and repair. Please check the photos for the condition. If you have any questions, please ask before purchasing.
