The React Runner Mid WR ISPA 'Blue Void' is part of ISPA, the innovative line from Nike that stands for Improvise/Scavenge/Project/Adapt. As a part of the Nike Sportswear program, this shoe offers a unique and experimental expression of Nike design along with practical solutions. The Blue Void and Team Orange colorway showcases a water-resistant upper, crafted from the same material found in the internal waterproof liner of an ACG hiking boot. Completing the design, the shoe incorporates Nike React 87 tooling in a striking white contrast.
