These are a pair of shoes made from kimono fabric (komon). Size: 23.5cm length, 9.5cm width. They are firmly woven, so they are durable. They may feel tight when you first wear them, but they will gradually conform to your feet. If you want to tighten them, you can adjust them from the underside. You can wash them if they get dirty. Hand wash (do not rub) or machine wash (using a net). Dehydrate them, shape them, and then hang them to dry. Thank you for looking.
