The Nike Air Zoom Rival Fly 4 'Ekiden Pack' is taken from a four-piece footwear collection that pays tribute to Japan's long-distance relay runners. Dressed in colors inspired by the Japanese flag, the white mesh upper features contrasting red accents on the collar lining and lateral-side Swoosh, which is covered in blue flame graphics. The lightweight build is mounted on a Cushlon 3.0 foam midsole with a springy Zoom Air unit nestled in the forefoot.
