The 2014 Nike Free running collection makes a performance statement echoing those famous words from coach and Nike co-founder Bill Bowerman. Bowerman’s belief was that design should focus on the athlete’s body and movement. His convictions inspired a design philosophy around the concept of natural motion and sparked the idea for the paradigm-shattering Nike Free introduced in 2004.

Ten years later, advancements in technology and product engineering continue to push the boundaries of footwear design even further in the all-new Nike Free 3.0 Flyknit, Nike Free 4.0 Flyknit, and Nike Free 5.0. “After 10 years of continual innovation, we’ve truly revolutionized the way these shoes work,” said Rob Dolan, Senior Footwear Design Director, Nike Running. “By utilizing new technologies and the principles of natural motion, we’re really able to allow the foot to move for the runner in a way we’ve never been able to do before.”

A key breakthrough came from Nike’s sport research lab data, athlete insights and studying the foot in motion. While runners move forward linearly, their feet don’t move in a perfectly straight line – they tend to roll slightly when striking the ground. The design team knew multi-directional flexibility was key to delivering natural motion in a shoe. To achieve this, the 2014 collection features three of the most significant developments in Nike Free since its 2004 launch.
