Vans has introduced a new take on some of its best-known silhouettes, made from responsibly sourced materials. The new capsule collection, dubbed the “Eco Theory” line, features new takes on the AuthenticSlip-On and Style 36 models. For the Eco Theory, Vans has used materials like natural rubber, organic cotton, jute laces, cork-lined footbeds and water-based inks and glues.
