The Nike Flyknit Trainer+ Unisex Running Shoe (Men's Sizing) was designed based on insights from the world's best marathon runners. Like the Nike Flyknit Racer, it features a virtually seamless knit upper for targeted support, breathability and a snug fit.
The one-piece knit upper of the Nike Flyknit Trainer 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.
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.
