Please read the profile. All were worn around the same time. The length of the soles is 10 cm. I think the size is around 15-18, but please check with your own socks. The fluffy bear socks in the second picture were hardly worn. The socks in the third picture were also worn a few times, about 2 times. The socks in the fourth picture were worn a few times, all three pairs. The Nemo socks are cute.
