Unused and unworn, but without tags. This is a kids' item, and the size is marked as 23 cm, I believe. I, an adult, wear the same ones, and I think they would fit someone with a foot size of around 22 cm. My feet are thick and prone to swelling, so the opening is a bit tight for me... Please refer to the measuring tape in the images and compare it to your own socks for consideration.
