I don't think these shoes have been used much. My foot size is 23.0cm, but my feet are narrow. There's a gap of about 5mm behind my heel, so I've only worn them once. If the size fits, I think they're lightweight and comfortable shoes. The size is M, so I'll list them as 23cm. Small jewels are attached to the fabric. I plan to ship them via Takkyubin Compact or Yu-packet Plus.
