Nike have just announced the 11th version of their Free collection and claim the new shoes take the next step forward in harnessing the natural motion of a runner’s feet and body.
The collection is available to men and women and is made up of three separate products. The Free 3.0 Flyknit reportedly offers the most natural ride with a Flyknit upper and a 4mm heel-to-toe offset. This is followed by the Free 4.0 Flyknit which offers more cushioning and a 6mm offset.
The final offering is the Free 5.0 which is the most cushioned of the collection and has an 8mm offset and an engineered upper.
Nike believe that their sock-like Flyknit upper and lightweight design delivers the flexibility that provides a more natural running experience.
Due to the hexagonal flex grooves on the outsole of the collection, the shoes are said to provide a fuller range of motion that lets the foot adapt to the ground.
Despite being lightweight and flexible, the shoes still purportedly retain an element of comfort thanks to the Phylite foam cushioning and the virtually seamless one-piece upper.
