My wife wears women's size 8 and the large was a bit larger than desired - actually, I'm a mens size 9 and they fit me.  I will update this review after we've washed them a few times, as I am expecting them to shrink a bit.  We prefer to hang dry our woolens, but in this case we plan to send them through the dryer a few times.  Otherwise, comfortable and very, very thick.  A touch scratchy at the top against your ankles, but this is par for the course for this type of sock, we don't find it annoying, but some people may.
