If you’re like me, you probably have at least one really old pair of shoes lying around somewhere. They’re too old/holey/torn up to wear, and yet you cannot find it in your heart to throw them away, discarding all those hours of hard work from child labor in the Philippines. But hearken, there’s a way to recycle your old sneakers!

Good ol’ Nike has set up a shoe recycling program, wherein you turn in your old shoes and they ship them to a processing plant. At the plant, they separate the old shoes into 3 different materials (rubber, foam, and plastic) and grind them up. They’ve recycled more than 21 million pairs of shoes since 1990!

Once they’re ground up, they can be turned into running tracks, new shoes, basketball courts, or even new clothes. That’s a lot better than just throwing away your old shoes to just sit in a landfill for centuries. So take a look around your house, find some old sneakers, find the nearest dropoff location, and recycle your old shoes.
