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.The one-piece knit upper seamlessly integrates areas of high support, breathability and stretch where you need them most, without overlays, which add weight.A Nike Zoom unit in the forefoot offers low-profile, ultra-responsive cushioning.The waffleskin rubber outsole features a racing-specific diamond pattern, delivering lightweight durability and traction.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.Benefits:*Reflective elements for visibility in low light*Pull-tab on heel for easy on and off*Low-profile knit tongue for ventilation and comfort
