The size is listed as 13cm, but this design runs large, and my child wore them when their foot size was 13.5-14cm. There is some dirt, but they are still usable. These are Nike kids' shoes that are the first to receive the American Podiatric Medical Association (APMA) Seal of Acceptance. The seamless Flyknit upper, made with 80% recycled materials, provides 360 degrees of flexible support. The lightweight TPU outsole has high grip, providing excellent traction and durability. ★Bonus: If you need them, I'll include a pair of 14cm indoor shoes for nursery school. ※Price is without the box. Add 200 yen if you want the box. Also selling as a set.
