Size: 19.5cm These are child-sized zori-style slip-ons. I made them for my child's Shichi-Go-San (Seven-Five-Three) preparations, but since they did well with the zori on the day, they were only tried on indoors. They match any type of kimono, and the thong is made of beige fabric so that the feet don't stand out too much. I think they can be used by both boys and girls. The base shoes are Ion's kids' ballet shoes. The thong is not glued but sewn on, so if you cut the thread, you can use them as indoor shoes after Shichi-Go-San. The insole is separate, so it's easy to wash, which is recommended if you use them as indoor shoes. Please refrain from purchasing if you are looking for perfection, as this is a handmade item. I think Ion's ballet shoes are made a bit large, so I've added a photo of the insole size. Please use it as a size reference. They will be shipped via Yu-Packet Post. The heels may be slightly compressed when posted.
