As custodians of mother Earth, the folks at OAT take their job seriously. What they’ve created is an entirely biodegradable shoe, made of hemp, cotton, cork and special plastics, all of which are shown to biodegrade within about six months. What’s more, the tongue of the shoes contain a “seed sheet” impregnated with wildflower seeds that, in theory, sprout after you’ve buried your shoes. What is even cuter, though, is their new OATies baby shoes. Each biodegradable pair contains tree seeds – so when your child outgrows their shoes, which they most certainly will, you can plant them and have to show for it a tree in honor of your little one.
