Nike just introduced the Flyknit technology, a shoe fabrication process with a structure and support knitted in that considerably reduces weight while being formfitting and offering superior breathability. The structure loosens and contracts with the foot to create a second skin feeling just like a sock. Combined with the Lunarlon cushion sole, the Racer model only weighs 160g (5.6 ounces) and will be worn by the world’s best marathon runners during the London Olympics. See the story behind the technology as well as the commercial in the videos below. Enjoy!
