18cm My child wore these shoes only once for a piano recital. Judging by the wear on the soles, I believe they were only used once. They are in overall good condition. They have been stored in our shoe cabinet at home since then. The original shoe box is not included. I will sell these to someone who understands that they are used children's shoes. Instant purchase is welcome ☺︎ I don't have many opportunities to use them, so I hope someone else can.
