"Oh, the Stan Smith. Championed by the two-time Grand Slam-winning tennis champ. Beloved by millions. Even after its winning attitude walked off the courts and onto the streets, it's stayed true to its DNA with a simple upper, understated style and serious comfort. This version of the adidas shoes answers the challenges of today. It's made recycled materials up top and recycled chewing gum in the outsole.
This shoe uses an outsole made with a special material which contains 20% recycled industrial chewing gum waste. The material is developed and sourced by UK-based Gumdrop Ltd. adidas Originals supports Gumdrop's mission to give a second life to the vast quantity of waste chewing gum that is not biodegradable. This product is also made with Primegreen, a series of high-performance recycled materials. 50% of upper is recycled content. No virgin polyester."
