INNOVATION ON THE GO
Redesigning the City Knife's collapsible, transportable construction with flexible Flyknit, the NikeLab City Knife 3 Flyknit Women's Shoe is pure innovation. With a look for everyday wear, this shoe provides comfort anywhere you go.
Flyknit OriginsNike Flyknit technology was inspired by feedback from runners seeking a shoe with the snug (and virtually unnoticed) fit of a sock. 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, formfitting and virtually seamless upper. This unprecedented precision maximizes performance while reducing material waste by an average of 60% compared to traditional cut and sew, saving millions of pounds of material from reaching landfills.
