What do Disney's Kermit, Marvel's Hulk and Disney's Mike from "Monsters, Inc." have in common? They all know it's not easy being green, but it's important. These men's vegan shoes are made with Primegreen that is made from recycled material, part of adidas' commitment to end plastic waste. They still look and feel just like the OG Stan Smiths but a graphic on the side reminds you to be a little more green like Kermit the Frog. Give a nod to two icons at once on these adidas shoes: tennis champ Stan Smith and Disney's Kermit the frog. Stan brought us the classic style that pairs with anything and fits in anywhere. The green amphibian? He's here as a reminder that even though it's not easy being green, it's important. In fact, we could all be a little greener. These shoes make an effort by swapping out classic leather for recycled materials.This product is made with Primegreen, a series of high-performance recycled materials. 50% of upper is recycled content. No virgin polyester.
