Jim,
I was doing my nightly research on the web and discovered a great resource for making Expedient Footware [1]. This seemed a slick and quick answer. Check out this link for the directions on fabricating sandals out of tires. I printed a copy of the instructions and they will become part of my library for that rainy day event we all hope never happens. The children and I will make our practice run set here shortly. – Matt B.
