Before you send your shoes to Goodwill look at these recycling programs. It is easier to drop them off at Goodwill, but with these programs you know they are put to good use. The only problem is you have to ship them. Maybe if more people start participating more drop off locations will be added.
Soles 4 Souls- This organization is based in Nashville, however the distribution centers are in Alabama, Virginia, and Nevada. So you still have to ship them.
Let Me Play- Nike runs this organization. They recycle old athletic shoes into material used in sports surfaces like basketball courts, tennis courts, athletic fields, running tracks and playgrounds for young people around the world. These have to be shipped as well.
SolesUnited- This program recycles old crocs into new shoes for people in need around the world. Of course, they have to be shipped as well.
I am willing to collect old shoes from people locally and ship them to the various organizations. Just let me know if you have any old shoes and want to do that!!!
