pair #1
note the wear on the sandals, the edges are not sharp, this is the first thing in look for in a sandal, the vets had sandals made in the local village and brought them home or used them for shower shoes and current made ones don't exhibit this wear or character
note the tread design, they were made from the same tire, and show the same amount of wear. The innertube straps are worn off on the front of the shoe
