If my little ones feet or socks didn't turn black every time he wore them Id give 5 stars. The shedding and dying is a disaster. Its unfortunate because all he asks is to wear them all the time but I cant handle the mess it makes after. So they stay at papas cabin now. Maybe the light colored ones are better and will try them out. Other than that they are well made on the outside and have thick enough sole he could play outside.
