This is a set of two pairs. They were used as emergency shoes and indoor shoes at a nursery school. Therefore, they were only worn once a month for evacuation drills. Since they didn't wear shoes for their age, they were hardly worn, but please check the photos. The 13.5cm beige pair has a peeled area where the size is indicated because a name sticker was attached. No heel wear. These shoes are very easy to put on! I don't have time to wash them, so thank you for your understanding.
