Like many Air Max designs of the late 90s and early 2000s, the Air Max Tailwind 4 was known for its gradient uppers. This new colourway of the 2019 retro goes for a different sort of treatment, featuring a psychedelic wavy pattern.
Bordered by black, the sneaker's blue and red frequencies are found across the ribbed mid panel along the medial and lateral sides of the upper. The black sections are not left plain either, using marbled effects with aplomb.
Perhaps if you stare at these for long enough, you might see something... or not. Get them soon from Nike retailers.
