As it turns out, it is easy being green! adidas teams up with the happiest place on earth for the Stan Smith "Kermit the Frog." Green in more ways than one, these sneakers are made from recycled material, part of adidas' commitment to helping end plastic waste. They still look and feel just like the original Stan Smiths, but a "Kermit" graphic on the side reminds you to be a little more green like Kermit the Frog. This product is made with Primegreen, a series of high-performance recycled materials with 50% upper made from recycled content.
