Adidas presented a new limited-edition sneaker for the fifth anniversary of its collaboration with Parley for the Oceans. The company said it would donate €30 to the NGO for each pair of the model sold in the first three days of the promotion. The partnership between Adidas and Parley for the Oceans was launched in 2015 at the United Nations to help reduce plastic marine pollution by collecting and recycling plastic waste. To pursue this goal, Adidas recently announced that it would stop using virgin polyester for its collections by 2024. By the end of 2020, more than 50 percent of the polyester in all of the brand’s products should come from recycling. Cyrill Gutsch, founder and chief executive of Parley for the Oceans, said the next step in the collaboration will be the development of a completely new generation of materials, using technologies that “build on what we see in nature.” Adidas claims to have made around 30 million pairs of Parley shoes since the partnership began.
