Mirroring the adult shoe in looks if not its full array of tech, the Nike Free RN 2017 TD 'Polarized Blue' stands out with bold color in a unique marbled visual effect. The seamless knit upper promises full breathability while synthetic skins reinforce the heel for ample support, while deep Nike Free flex grooves give them the feel of running in bare feet. The hook-and-loop closure makes for easier on and off, essential for active kids.
