These are indoor shoes. I received them as a hand-me-down, but my child's kindergarten requires specific shoes, so I'm selling these. They've hardly been worn and are in good condition. I'm not sure of the size because they're from overseas, so I measured the insole. It was 17 cm, so I think they're probably a size 17, but it's not written on them. Would you like to buy them at a low price?
