Liverpool and Adidas are committed with the use of production methods that reduce environmental impact. Both brands partnered to collect PET inside some of their stores in an effort to gather the greatest number possible of plastic bottles. The making of each pair of Parley shoes requires 11 bottles and in only 15 days 15,000 bottles were collected, a total of 450 Kg will be reused into making tennis shoes form the Ultraboost- Parley collection. With this partnership more than 1,3000 pairs were created.
