Nike unveils new products in environmental push

Once all Nike products meet these benchmarks, it will translate to Nike reducing waste in its supply chain by 17 percent and increasing the use of environmentally preferred materials by 20 percent.

The first shoe to embrace the "Nike Considered" principles was the Air Jordan XX3 shoe, unveiled in January. The clean and modern-looking shoe is made from recycled plastic and scrap materials with no toxic adhesives. Instead, its stitching provides support and helps hold the shoe together.
