adidas Originals' 'Superstar' sneakers have been one of the brand's most popular styles since the '70s, but this year the iconic pair has a new, eco-friendly update aimed at reducing waste. From the 'Clean Classics' collection, this reworked version has speckled rubber soles and vegan leather uppers made from 70% recycled content. The linings are made from repurposed polyester, too.
