These are 16.5cm Shunso sneakers. They were used indoors and for a school presentation (outdoors). They were worn outdoors about 3 times. Otherwise, they were worn indoors once a week for lessons. Shunso sneakers are designed with children's feet in mind, and my daughter said they are very comfortable to wear. The soles are dirty, but they haven't been worn often and weren't used for everyday wear, so I think they are in relatively good condition. Please understand that these are used items.
