These shoes are being sold because the width doesn't fit when walking. They've only been worn once. I'm not sure about the Japanese size, but I think it's around 23.5. The material is leather, and it's a Dr. Martens with a more understated design. - Color: Black - Material: Leather - Sole: Clear sole - Stitching: Yellow - Design: Lace-up Feel free to ask any questions.
