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.
