Truth be told, Nike perfected the ‘running shoe’ years and years ago, so whatever new innovations and engineering marvels come out of Beaverton are only going to raise your game. The latest advancement, introduced earlier this year, is FlyKnit – a weave of super-lightweight fibers that comprise one no-sew upper shell that maximizes fit and breathabililty. These two new #FIRST2FLY colorways made for Team USA for the Track & Field Trials exemplify the unique nature of FlyKnit, where two different colors can be combined into one for a distinct appeal – only these two are already sold out. More Flyknit Trainer+ colorways will hit retailers very soon, so check out the USA Track & Field Trials editions below and let us know if you think Flyknit is one of the best innovations Nike has put out over the last decade!
