Just saw this commercial and had to share it. It is absolutely a brilliant concept that they are capturing air from their sponsored athletes and putting it into the shoes! Love the bit with John Mcenroe as he is a funny guy. While we were in Brazil training on Ipanema beach, we would up getting a photo with him in our speedo's on our festive moustache friday! He was totally grossed out by our traditions but the guy has style and a pretty solid wrap in tennis so we let it slide.
