Worn out sneakers are some fairly nasty business, and not just 'cause they stink. Rubber, leather, and ink aren't the most compostable things on the planet. There's not a ton of options for recycling shoes either. Enter Dutch footwear brand OAT Shoes, which recently dropped a 100% biodegradable series of kicks that rightfully won the company a green design award at Amsterdam Fashion Week. Called the Virgin Collection, the decomposing sneakers have seeds embedded in their tongues, so when they wear out, just bury them and watch the flowers bloom.
