if your heels are worn down that badly you may want to adjust the way you run or land. the heel of a shoe shouldn't wear down very much compared to the toes and ball of the foot. other than that good work on those shoes i alway keep my busted shoes as trophies so i can see where this video is coming from.
So what you are meaning to say is, buy a new pair of damn shoes Noah!!! Really Noah, damnit, how many other people must you hear this from lol!!!
