These are foldable pumps. The soles are soft, so they can be folded up and carried, as shown in image 6. I found them very useful for attending weddings. I would wear these shoes to the venue and then change into heels there. They have been worn outside, but they can also be used as indoor shoes if the soles are disinfected. There is no size indicated, but I have confirmed the size through my online purchase history. Color: Black Size: 23.5 I bought these several years ago and used them a few times, but haven't had many opportunities to wear them since. There are no noticeable scratches or stains, but please understand that these are used items stored at home. As they are foldable, I plan to ship them via Yu-Packet Post with the heels folded.
