Nike embarked on a four-year mission with teams of programmers, engineers and designers to create the technology needed to make the knit upper with static properties for structure and durability. Then the precise placement of support, flexibility and breathability—all in one layer—was refined. The result is a featherweight, form-fitting and virtually seamless upper. This unprecedented precision maximises performance while reducing material waste by an average of 60% compared to traditional cut and sew, saving millions of kilograms of material from reaching landfills.
