"Scrap materials, the end of an ordinary box, scraps of leather or canvas, are all you need to manufacture a pair of comfortable, serviceable play shoes." So says the introduction to this Sunset article from 1943 on how to make your own "Caterpillars." I'd rather have these than those embarrassingly smug Adbusters sneakers. Link (If the link gives you problems, use the access code KAYAK to gain admittance. What a dumb rule!) Boing Boing reader Joel found a shortcut link to the image.
Seamus sez:
Another pair of make-at-home shoes.
Tire sandals with nothing but a tire and some webbing (and tools of course).
Perfect for hiking!
I especially like the anecdote from the old German at the end talking about post-war hardships influencing footwear and bicycle tires.
