Worn-out shoes? Instead of buying new ones, you can bring them to a local cobbler to put in new heels or soles. Repairing them uses up less material than making a whole new pair. Same thing with clothes. Just bring them to a tailor or dry-cleaning place that makes alterations. Nike has a Reuse-a-Shoe program that accepts any brand of athletic shoes for recycling. Or you can send gently-used footwear to needy people in other countries through OneWorldRunning.
