Thank you for viewing! There are many scratches! I bought these before the season, but I only used them once, and they didn't seem to fit my child's feet, so I no longer need them. The inner boots are deteriorated, and there's also a smell! I tried to air them out and manage them, but since I'm not using them, I'd appreciate it if someone who needs them would take them. I don't know about the hydrolysis of the soles. They're still usable though (lol) Returns are not accepted. Please understand the meaning of "junk" before purchasing. Questions are welcome. Kasugabe area, Saitama Prefecture Pick-up is also welcome!
