The Flyknit Racer’s upper is entirely constructed from Nike’s synthetic yarn. The one-piece construction means there is very little waste or excess. The weave also makes for an extremely breathable shoe, something that was sorely lacking from Nike’s Lunaracer. It’s possible to literally see through the weave in certain places and see your foot beneath. Running and racing in the summer is a joy in these, thanks to the ventilation, and I can definitely feel the difference when I change into other running shoes of mine. Of course, breathability also means things can get inside the shoe easily, namely water. During the winter, I regularly race 5ks and the cold air is less welcome; if it rains (it normally does in Britain), my feet get soaked.
The Flyknit Racer’s upper has a contrasting colour scheme to it, with the outer area of the foot predominantly decked in the shoe’s primary colour and the inner foot in the secondary colour. The Nike swoosh has been printed on using a paint that I can only describe as looking like white wash, with a powdered look.
