Nike Free 2015
The evolution of the Nike Free continues in 2015, the shoes 11th year. The new models harness the natural motion of a runner’s feet and body by honing down to the design features that give runners a natural running experience.
The new collection focuses on the principle of less: eliminating layers, seams and bulk. The final product is all about the power of the foot- not the shoe:
- Nike Free 3.0 Flyknit: Nike’s most natural ride with a snug Flyknit upper and 4-mm heel-to-toe offset.
- Nike Free 4.0 Flyknit: A cushioned, natural ride with a contoured Flyknit upper and 6-mm offset.
- Nike Free 5.0: Nike’s most cushioned, natural ride with an engineered upper and 8-mm offset.
Each shoe includes naturally flexing soles, with the Nike Free 3.0 Flyknit and the Nike Free 4.0 Flyknit having virtually seamless one-piece Nike Flyknit uppers that conform to the shape of a runner’s foot and offer support at the same time. The Nike Free 5.0 has also shed layers this year, resulting in better lightness and breathability.
While some running shoes benefit from a structured, plastic heel counter on the back of the shoe, the Nike Free 3.0 Flyknit uses Flyknit technology to support the heel. The Nike Free 4.0 Flyknit uses a non-stretch yarn in the heel area to add even more stability and support to those who need it. Removing the structured heel counter frees up the runner’s natural gait and pares down weight.
Another benefit of Flyknit is less waste- which can be knitted into near seamless uppers instead of multiple materials cut and sewn together.
