The Nike Flex 2018 RN GS targets natural motion in a minimalist silhouette for running. Arrived in June 2019, this kid's variant comes in a black circular-knit upper with a reinforced heel counter and Flywire cables in Racer Pink. Color-pop Swooshes are applied to either side and a signature wordmark graces the tongue. The sneaker's dual-density Phylon foam midsole and tri-star rubber outsole offer a flexible ride.
