One World Running promotes health in the United States and the developing world by sending new or nearly new athletic shoes to American shelters as well as Africa, Central America, and Haiti. If your shoes aren't quite "nearly new," they'll be recycled into material for tracks and playgrounds.
Every Type of Shoe
Souls4Soles has given away nearly 12 million pairs of shoes to people in need. Donations can be left in the organization's numerous drop boxes nationwide or shipped to any of its three warehouses.
