The Nike Free 4.0 is a uniquely designed performance sneaker that draws inspiration from competitive runners. Crafted using a seamless mesh material, this updated version in 'Black Silver' is enhanced with transparent synthetic overlays, which not only provide additional support but also ensure proper airflow to keep your feet cool. The contrasting Side Swooshes and tongue branding add a visually appealing touch to the overall look of the shoe. Beneath, the Phylite sole is specially engineered with flex grooves and waffle pistons, delivering excellent traction and flexibility to enhance your performance.
