The collaborative effort between adidas and environmental organization, Parley for the Oceans, is evident with the release of the Parley x NMD_R1 STLT Primeknit 'Core Black' sneaker in November 2018. This sneaker is constructed using Primeknit mesh, which is woven with yarn made from Parley Ocean Plastic. This unique material is sourced from recycled waste found in beach and coastal communities. An added feature of the shoe is the stabilizing EVA plugs that reinforce the upper, providing a secure fit. Working in conjunction with the Boost midsole, these plugs contribute to the overall comfort and cushioning of the sneaker.
