The Nike Superfly Air Zoom Pace II mens shoe contains new Flywire technology.
Flywires are tensile fibres on the shoes upper which provide maximum support using the least amount of materials. Inspired by Suspension bridges, these are individual, free- running cables made from high-performance nylon anchored at the eyestays and bottom of the shoe to provide incredible strength, hold and flexibility. Flywire acts like super strong synthetic ligaments that wrap around the foot to provide light weight support and comfort for your feet.
