Blue QWomen's Novelty Ankle Socks (fit women's shoe size 5-10)

Why is leather listed in this item?

Are all of these socks the same height? Some say crew and some don’t. I have the “delicate flower’ version and I’m happy with how high they go up.

How do i choose a sock size for a youth? with shoe size 3

Why does it say both "100% cotton" and"40% combed cotton, 58% nylon and 2% spandex" in thr details?
