Running shoes looking beat? Lacking the tread or support you need for a good workout? Don’t fret: Their lifespan may be far from over. Thanks to Nike, their second shot at life is just beginning as a surface material for tracks, playgrounds, courts and much more. The comprehensive Nike Reuse-A-Shoe Grind Program regenerates original materials and products into not only the aforementioned surfaces, but transforms them into new Nike footwear with what the company bills as “unprecedented adaptive performance.” In fact, Grind materials can be found in 71% of the products in everything from yarns and trims to some of the brand’s most premium jerseys and shoes. It’s the ultimate sports(wear) comeback; Nike.com.
