This is a Red Wing Engineer Boot. The model number is 2268, size is US9, which is equivalent to 27.0cm in Japanese size. I purchased these used several years ago, but I haven't worn them much myself, so they are in a condition similar to when I bought them. I wore them casually for everyday use. I haven't used them for riding a motorcycle or anything like that. They are originally used items with some scratches, scuffs, and yellowing, so please only purchase if you understand and accept this.
