Description

Perfectly designed for active kids, the Nike Flex Runner 3 features a breathable textile and leather upper for superior comfort and durability. The stretchy bootie design secures the foot firmly in place while the flexible foam sole gives them the bounce they need. With deep flex grooves, this running shoe enables easy movement in all directions. The multi-surface traction pattern provides grip and stability, while the reinforced toe tip guards against wear and tear. The convenient heel strap ensures the shoe stays put during vigorous activity. Heel and tongue pull tabs allow for easy wear, and the lace-free construction offers a hassle-free experience to your budding athlete.
