I see this from time to time w/elite racing at middle and long distances in all
levels of weather and have never gotten a clear understanding of the purpose.
Anyone out there know...ideas...wild guesses?

That's Keflezighi in the socks on Sunday in NYC. Is there any thermoregulation
strategy behind this w/calf muscles or something? Or is this simply purely a
rare personal comfort thing with no further purpose behind it? Certainly
can't knock it...the guy almost won & did walk away with over a $100K at the
end of the the race.
Anyone out there run like this?
