Let’s get right to it. This shoe alone won’t save the world. We even put that right on the shoe. But it is a start. What does that mean? It means that these adidas Continental 80 Shoes are made with recycled materials, a non-leather upper, an algae-based midsole and natural, renewable rubber. The classic look is the same as the OG, just a different approach. Evolution is cool like that.This product is made with Primegreen, a series of high-performance recycled materials. 50% of upper is recycled content. No virgin polyester. It also features an algae-based EVA foam that helps clean at least 30 litres of polluted lake water.
