Knee Highs

Why don't I see more knee high socks?? It should be common knowledge that these are universally hot. Seriously, any army on earth could be immediately halted by a group of schoolgirls, female soccer players and chicks with cold legs. Japan figured it out decades ago. I know that summer is officially over, but there is still time to show some of that mid-thigh-to-knee area before it gets too cold to even go outside.
