Where the Air Max 1 exposed the air unit and provided a chance for you to peak inside the inner-workings of a sneaker, the Air Max 90 highlighted an enhanced Air bag with a bold infrared window, effectively making them impossible to miss. While the Air Max 1 stuck with primary red and blue colorways for its original drops, the Air Max 90 played to the sensibilities of the time with its original “Infrared” colorway. The very ’90s neon red/pink concoction—better known as, you guessed it, “Infrared”—was as bold as the new Air approach and was offset by black, white and grey throughout the shoe. dnp for sale
