Flywire
Flywire helps provide ultra-lightweight support and comfort for your foot. It gets its strength from thin nylon fibers strategically placed on the upper of the shoe to hold the foot in place, helping to reduce slippage during activity. This allows for a massive reduction in weight because material is used only where it’s needed.

Flyknit
It uses a knitted upper construction process that increases support for a comfortable, custom fit. Seams, weight and friction areas are all reduced. Polyester yarn is more open in areas that need more flexibility and tighter in areas that require more support. Nike Flyknit also eliminates the need for multiple materials used to make traditional shoe uppers, significantly reducing pollution.
