Designed for running, the Nike Free RN 2018 GS is a flexible sneaker made for children. This 'Speed Red' edition is a monochrome take on the shoe, dressing its mesh knit upper in all-red from heel to toe. Integrated Flywire cables enhance the Dynamic Fit system that uses a wide, stretchy strap at the heel and taller collar to help support growing feet. A dual-density foam midsole with an updated tri-star pattern underfoot complements this design.
