The Nike Air Structure Triax 91' like many of Nike’s running shoe offerings from the turn of the decade, was noted for their ample and consistent use of color pops. Against white, grey, or black bases, the Swoosh selected a bright neon hue of red, blue, or green to add a visual element to their design, and that formula has proven successful in terms of getting eyeballs on their product. But for this upcoming release of the Air Structure Triax ’91, Nike is option for a colorless approach, adding a black, white, and grey colorway to the layered running shoe.
