Well, I have tried the contact adhesive and ground rubber mixture for soling moccasins. On several pairs. I walk a reasonable number of miles weekly on tarmac and concrete. I find the contact adhesive and ground rubber soling wears very quickly. Too quickly.
One solution for extending the life of my mocs is to make the soling thicker by spreading more layers of the mixture on to the underneath of them. But it is time consuming and the fumes are unhealthy. The other solution, which is far more appealing, is to just use thicker leather for the soling. Probably buffalo. Or bison on your side of the pond.
I would like to know whether the leather soles on the moccasins made by Arrow Moccasin Company are resistant to water. My experience is that leather soaks up water once the finish on the grain side is worn off. If the soles on the Arrow mocs are not resistant to water, then why do folk buy them?
