LIGHTWEIGHT COMFORTThe original Nike Air Presto, originally released in 2000, was created as a kind of T-shirt for the foot, with a breathable and incredibly flexible sock-like elastic upper. Today, the Nike Air Presto Ultra Flyknit Women's Shoe updates the original with formfitting Flyknit for ultra-lightweight comfort.BenefitsFlyknit upper conforms to your foot for lightweight supportSignature TPU cage delivers midfoot supportSockliner and outsole cut-outs enhance breathability and flexibilityInjected unit midsole provides lightweight comfort and durabilityMid-cut collar delivers a snug, supportive fitWaffle-inspired outsole with durable rubber pods for tractionFlyknit 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.
