I remember putting socks on my baby before they could walk, using them for a short time, maybe once or twice. Since they weren't walking, the soles are in new condition. After that, I stored them in a bag indoors. The inside is fluffy, and they are in near-new condition. They are a very cute color, and I hope someone who can use them will consider purchasing them. Size: 6-12 months. The size is only listed as this, but when I measured the rubber sole, it was 14cm, so I estimate the inner sole to be about 11-12cm. Please understand that this is a rough measurement, and I hope those who can accept this will consider purchasing them.
