Nike Free Run 2
Released: 2011
The Nike Free Run 2 managed just the right balance of aggressiveness and grace to appeal to both male and female wearers. Such style served as a re-launching pad for the technology that debuted back in 2004, with consumers using the flexible footwear for casual and athletic activity. The upper took well to color and was even adapted for the following year’s Air Max model, while Free cushioning jumped to the forefront of Nike footwear.
