The name says it aLL. Nike wanted to lessen its carbon footprint with these & did so, creatively. The upper made with Space Waste Yarn, itself constructed from recycled plastic water bottles, T-shirts, and yarn scraps, then, with the cycled Nike ZoomX foam insoles. These have touched the pavement but not much and have lots of life left. Excellent Used Condition No Box No Stains, Rips, or Holes 100% Authentic
