The Free Run has been an extremely successful model the past few years for Nike. This comfortable "natural motion enhancing" creation is on everyone's feet from the gym and track to the office and supermarket. The latest model in the series, the Nike Free Run+ 3, builds on the model's success with a modified design. They feature a seamless and breathable upper, molded sockliner, low profile midsole, asymmetrical lacing, and flex grooves on the outsole that enhance flexibility and help maintain stability. Plus, the Nike Free Run+ 3 also has the Dynamic Fit system, which consists of a "cage" that wraps around the midfoot and can be customized to your preference by tightening the laces.
