The Nike Free offers a snug fit and incredibly lightweight feel to accompany you on your runs and in your daily activities. Made with at least 20% recycled content, it combines the flexibility you love with reliable support that keeps you close to the ground, as if you were walking barefoot. The new foam is lighter, softer and more responsive than previous versions, giving you maximum comfort with every move, whether you're walking on pavement or the track. This redesigned model features a more responsive, lighter and softer foam than previous versions. Laser-cut flex grooves provide more flexibility, while rubber on the forefoot and heel ensure maximum durability. The upper is made of a breathable mesh for an exceptionally soft and flexible feel. It provides room for the foot to expand as you run. Flywire technology is integrated into the laces on the side for optimal midfoot support. As with previous versions of the Free, the heel offers the same cushioning you love for a comfortable fit. A heel tab makes it easy to put on and take off the shoe.
