Nike Grind is part of Nike’s Reuse-A-Shoe program that was started in 1993. The purpose of the program is to eliminate waste and close the loop on Nike’s product lifecycle by collecting post-consumer, non-metal-containing athletic shoes of any brand, including Nike shoes that are returned due to material or workmanship defects.
Once collected at the Nike Factory Store – Tempe, the sneakers are ground up and separated into three distinct types of material: rubber from the outsole, foam from the midsole and fabric from the shoe’s upper. Nike and its partners (Atlas Track & Tennis, Playtop, Training Ground, Everlast and Rebound Ace) take the granulated rubber and create soccer, football, baseball fields, weight room flooring and running tracks. The first+B1 synthetic turf soccer field installed with Nike Grind rubber was Douglas Park in Chicago. That surface was donated by Nike and the U.S. Soccer Foundation. Nike uses the granulated foam from the shoes for synthetic basketball courts, tennis courts and playground surfacing tiles. The granulated fabric from the shoe uppers becomes the padding under hardwood basketball floors.
These programs are located in Australia, Canada, Japan, United Kingdom, and United States.
