The Nike Free RN 2017 was unveiled in April 2017 for freedom of movement and a lightweight stride. Designed with mesh, the 'White Black' upper elicits structure with more tightly woven textures in specific areas, while open-knit stitching at the toe delivers breathability. Laces move through Flywire cables up top, creating a tighter fit throughout. Down below, a Nike Free sole unit offers flex grooves for a flexible and natural feel.
