Aside from their speed and finesse, Nike is helping the U.S. Track & Field Champions stand out when competing at the world championships scheduled for this week in Moscow. A far cry from the volt yellow and grey that marked the apparel from last year's Olympic Games at London, this line-up sees the athletes don "Gamma Blue" and "Pink Foil" for the ladies. As usual, the footwear is infused with the latest in Swoosh technology, including the ultimate lightweight materials across the Nike Zoom Superfly R4, Ja Fly, Maxcat 4, and Celar 4 sprinters, Lunarracer and Flyknit Racer for distance, and Javelin Elite and Rotational 5 for the field, among others. "When we talk to athletes," according to Nike's VP of Creative Director of Running, " we hear from them that bold, vibrant colors make them feel invincible in competition."
