Nike's Flyknit technology has emerged as one of the most significant developments to come out of the brand's Innovation Kitchen. Debuting at the 2012 London games on the Nike Flyknit Racer, the material is traditionally constructed by knitting a flat upper that's attached to the midsole. The next generation of Flyknit sees the introduction of a complete 360-degree form, wrapping the entire foot in a second-skin feel for a more secured and controlled movement for athletes. This is achieved through a locked-in fit, with construction that reduces in-shoe movement, and added agility and quickness by minimizing the space between foot and ground. Another benefit of next-gen Flyknit is sustainability, as precision engineering produces 60 percent less waste than traditional cut-and-sew methods.
