The only growing resource is trash. But some trash, like worn out tires, can be saved from the landfill and put to good use. Besides that, how many shoes come with a 50,000 mile warranty?
Being sturdy and long lasting, as well as unbelievably inexpensive, tire sandals are in common use from Latin America to Southeast Asia. They may not be particularly stylish, but they do the job of protecting the feet from sharp stones and thorns. All it takes to make a pair is an old tire, a saw, some sharp chisels, and a little patience.
This one-piece design uses no glue, and no stitching, so there are no separate parts and pieces to come loose and wear out. This web page, Adapted from Participating in Nature: Thomas J. Elpel's Field Guide to Primitive Living Skills, gives you everything you need to know to make your own tire sandals.
