Tried on only indoors at home. I am selling because the size didn't fit. I usually wear 22.5cm, but it felt a little tight with socks. It's listed as 23cm, but I think it would be a good fit for those who wear around 22-22.5cm. These are portable slippers that are easy to use for school events, etc. They cannot be folded. - Color: Black - Design: Square toe - Style: Flat shoes - Material: PU Includes a storage bag. They can be used in 2 ways, as babouches by stepping on the heel. * When shipping, the heels will be folded, so there may be creases. Please understand this before purchasing.
