Free RN 2017 'Binary Blue'

The Nike Free RN 2017 'Binary Blue' is designed to maximize flexibility and breathability for light workouts and shorter to mid-distance runs. Its single-layer, seamless knit upper has different mesh gauges for targeted ventilation and an extra-light ride. Inspired by Stanford athletes who trained barefoot on the golf course, Nike designers Tobie Hatfield and Eric Avar created the first Nike Free in 2004, featuring deep sipes cut into cushy Phylon foam to mimic the feel of bare feet.
