Targeted Support

     The one-piece knit upper of the Nike Flyknit Racer seamlessly integrates areas of high support, stretch and breathability where you need them most-without overlays, which add weight. For an adaptive fit, lightweight dynamic Flywire wraps the foot and is adjustable through the laces.

Lightweight

     Nike Flyknit technology renders this racing shoe incredibly lightweight. The upper and tongue weigh just 1.2 ounces (34 grams), and the entire shoe weighs a mere 5.6 ounces (160 grams).

Nike Flyknit Origins
     Nike Flyknit technology was inspired by feedback from runners craving 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, form-fitting and virtually seamless upper.
