The innovative Nike Flyknit Racer Unisex Running Shoe gets its structure and support from Nike Flyknit technology. As a result, it's incredibly lightweight, with a precision fit that feels like a second skin. It's no wonder the world's best marathon runners are wearing it in competition.
Benefits

Forefoot Nike Zoom unit and full-length Phylon midsole for lightweight, responsive cushioning
Waffleskin rubber outsole with racing-specific diamond pattern for lightweight durability and traction

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 34 grams (1.2 ounces), and the entire shoe weighs a mere 160 grams (5.6 ounces).
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.
Flywire
Flywire helps provide ultra-lightweight support and comfort for your foot. It gets its strength from thin nylon fibers strategically placed on the upper of the shoe to hold the foot in place, helping to reduce slippage during activity. This allows for a massive reduction in weight because material is used only where it’s needed.
Zoom
Nike Zoom cushioning is part of the Nike Air family, and—like its siblings—it’s lightweight and durable. Because Nike Zoom cushioning is incredibly thin, it brings the foot closer to the ground and enhances stability, especially during quick cuts and multi-directional movements. After impact, the tightly stretched fibers inside the pressurized air unit quickly bounce back into shape, providing a super-responsive feel and improved awareness of the surface you’re playing on.
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.
