Black flat shoes, size 23-23.5 cm - Color: Black - Material: Synthetic leather For indoor shoes at graduation ceremonies, entrance ceremonies, etc. I bought these for indoor shoes at school events and kindergarten events. I usually wear 23.5 cm pumps, but these were a bit small, so I think they are suitable for those who usually wear around 23 cm. The sole is soft, but it cannot be folded. I only tried them on.
