The Nike Adapt Huarache ‘Racer Blue’ makes use of a breathable black mesh upper with semi-translucent accents built into the sneaker’s groundbreaking FitAdapt power lacing system, good for a secure, locked-in feel. The technology augments the sneaker’s stretchy neoprene bootie and exoskeletal structure, which maintain the classic Huarache aesthetic. Functional LED lights shine within the white foam midsole.
