In 1987, the Nike Air Max 1 debuted with visible air in its heel, allowing fans more than just the feel of Air-Sole comfort—suddenly they could see it. Three years later, the Nike Air Max 90 let them see even more of it, arriving with a Visible Air window that was bigger than its predecessor. It hit the shelves sporting a fiery shade of red that set the sneaker world ablaze and became a Nike staple.
