The Nike Epic React Flyknit in White was released in February 2018. The Epic React Flyknit 'OG' sneaker takes cues from the adult release and reconstructs them into a kid-friendly version. Designed for growing feet, the shoe is constructed of ultralight Flyknit mesh that forms to the shape of the foot. Stabilized by a supportive heel cage, React foam technology provides a soft feel, impact protection and energy-returning capabilities.
