Discover Training Ground with Nike Grind
Exactly what is the Nike Grind rubber that is used to make Training Ground products? Using technology developed by Nike engineers, footwear manufacturing byproducts are processed and refined into the material called Nike Grind.

This is then blended with the recycled tire rubber and processed to make Training Ground products. Nike partners with industry-leading companies like ECORE to incorporate Nike Grind into their quality surfacing systems ranging from basketball and tennis courts, running tracks, and soccer fields to fitness flooring and playground safety surfacing.

Together, we’re working toward a common goal: to create the highest-quality sports surfaces available using the most innovative methods and advanced recycling technology. Visit nikegrind.com for more information.
