3D knitted spikes by Nike

Featherweight feet

The upper of the Nike Flyknit is like no other trainer or spike. Instead of being created from a number of panels stitched together it is knitted as a single piece (including the tongue). The upper has different properties in different areas. This allows the upper to be supportive where needed whilst also being breathable and incredibly light. At 110g it weighs roughly half of what a standard pair of spikes would. As an athlete (realistically an ex-athlete but I haven’t quite hung up my spikes), this sounds incredible. The lighter the shoe, the less energy you waste by making your feet heavier. Also, the more connected you feel to the ground which can help to improve running technique. The manufacturing engineer in me is intrigued by the 3D knitting process that came out of 4 years of R&D and required new machines to be developed. Perhaps understandably Nike don’t seem to have made public much technical detail of how these magical knitting machines work. That’s one factory I would love to have a good look around!
