The Nike Air Max 90 'Volcano' utilizes a black synthetic upper, featuring a textured finish that mimics the look of molten magma. Mottled black accents cover the fiery orange Swoosh and back tab, marked with embossed Nike Air branding. A woven Nike tag embellishes the breathable mesh tongue. Lightweight cushioning arrives via a solid black polyurethane midsole, contrasted by a yellow-tinged Max Air unit nestled in the heel. A waffle-traction rubber outsole ties back to Nike running heritage.
