Got a pair (or a pile) of old sneakers that are too worn out to give to charity? Nike will recycle any brand of athletic shoe through its Reuse-a-Shoe program. You can drop shoes off at any Niketown store or Nike Factory store; the company also has other drop-off spots, and if there’s not one near you, you can mail shoes in. (Get details on the Nike Web site.) The company processes and recycles the footwear to make sports surfaces for basketball courts, tennis courts, running tracks and playgrounds. Right now they’re collecting shoes to make athletic surfaces for New Orleans, to help bring youth sports back to the city as it rebuilds. To date, about 20 million pairs of athletic shoes worldwide have been recycled through the Reuse-A-Shoe program.
