The 2013 Flyknit Racer was among the first Racers to introduce a distinctive design where two different colors were used on each side of the shoe. The upper part of the shoe is made of Chlorine Blue and Dark Obsidian Flyknit, sitting on top of a white midsole. The contrasting look is completed with additional white details, such as the side Swoosh. This unique colorway is what sets this Flyknit Racer apart.
