They were advertised as wool socks but are actually only 40% wool (I'm not sure about that either as they don't look like wool to me). Not very well made either, my daughter keeps falling off her feet, very bulky (difficult to put on shoes) and uncomfortable to walk on. I'm very disappointed and would return them if I hadn't washed them.
