Invite a sense of calm to join you on your run with the grounded look and feel of the Nike Free Run 5.0. Its low-cut design is all about stripping down the nonessentials, leaving you free to concentrate on your stride and the nature around you. Plus, the breathable knit upper and low-cut design provide flexibility and stability while lightweight foam underfoot gives you the comfortable cushioning you need to power through your route. Comfort Fit Breathable, stretchable yarn hugs the foot above the toes to provide a snug feel. The stretch extends to the midfoot so it's flexible when your foot enters the shoe. Natural Moves Grooves on the sole allow for flexibility and let you move freely. It's wider under the midfoot for better shaping through the arch and support in the forefoot and heel. Stay Contained Flywire technology loops through the laces on the side for midfoot containment.
