Earlier this weekend we previewed the upcoming multicolor version of the NikeLab Air Force 1 Ultra Flyknit Low. Today NikeLab follows up with tonal Gym Red and Black versions of the updated icon. The uppers feature clean red and black Flyknit details, while they both sit on a clean white outer sole. The tongue, heel tab and Swoosh come in matching premium leather. Look out for a release of all three versions of the NikeLab Air Force 1 Ultra Flyknit Low on March 14 on nike.com/nikelab and at select NikeLab locations.
