These fit my daughter who wears a size 8.5 women's shoe and son who is a 6.5 in boy's shoes.  They're a little big for my son, but not so much that they're saggy, and he could easily cuff the top if he wanted.  Soccer socks that are meant for his size are often way too small since he has big calves.  Both say they're easy to put on and comfy.
