If you love the style of the Air Max 90, you're going to go crazy for the Air Max 90 Ultra — a more breathable, lightweight version of this classic staple. Breathable, lightweight leather and mesh upper with supportive overlays. Visible heel Air-Sole unit for the iconic cushioning you know and trust. PU midsole unit doubles as the outsole, dramatically cutting down on weight. Rubber in high-wear areas of the outsole for durable traction where you need it most.
