Cold Ankles?

Most of us know the feeling of cold feet both in the literal and personal sense but travel about 5 inches up the leg and you get this...

I like how the socks are bright red just incase the green cuffed pant doesn't draw enough attention to the open ankle..however it doesn't seem to bother this man so to each his own I guess 

Someone doesn't look too happy...could it be the lack of circulation in the lower leg?  We'll never know...
