The Wmns Epic Phantom React Flyknit 'Bright Melon' features ultra-lightweight materials and responsive cushioning for a natural, barely-there feel. This iteration was released May 2019 to expand Nike's summer running line in bold color, with a flexible, breathable Flyknit upper and contrasting heel clip for better balance and stability. Under the foot, React foam with a pressure-mapped outsole pattern creates maximum energy return.
