Nike just released the latest incarnation of its 'FREE' running shoes collection, the Nike Free 2014 series. The collection features three new arrivals to the Nike Free family, the Free 3.0, Free 4.0 and Free 5.0.
The shoes were designed taking into account data from Nike's sports research lab as well as insights from athletes. The end result is Nike's first-ever outsole with hexagonal grooves. This design provides multi-directional flexibility and enables runners' feet to move freely in all directions.
The shoes' heels are anatomically shaped and designed to roll as athletes' feet hit the ground. By mimicking the shape of the foot, this shoe design allows the wearer's feet and the rest of their body to move completely naturally.
