NIKE has engineered knit for performance to create running footwear. Employing a new technology called Nike Flyknit, yarns and fabric variations are precisely engineered only where they are needed for a featherweight, formfitting and virtually seamless upper.
Here comes the NIKE FLYKNIT RACER
With all the structure and support knitted in, the Nike Flyknit Racer’s upper and tongue weigh just 34 grams (1.2 ounces). The whole shoe weighs a mere 160g (5.6 ounces) for a size 9.
An additional environmentally sustainable benefit to Nike Flyknit is that it reduces waste because the one-piece upper does not use the multiple materials and material cuts used in traditional sports footwear manufacture.
