You might be able to get brown Dainite soles from B Nelson in New York:
This is fifteen different kinds of awesome! Great knowledge drop!
Playing Devil's Advocate is one thing. Trolling is another. As it appears there isn't a lot of progress being made in that discussion, can I suggest y'all drop it?
Also B Nelson... ;) (he does mail order)
But seriously, it would probably help if you stated what work you want done.
So welting, which to identify, is the strip that is added outside the shoe(for ease of conversation) on top of the sole used to be used prior to the machine method(goodyear or whatever). Blake does not use a welt however that is stitched directly to the midsole correct and that too is machine based? So shoemakers actually would use a welt as we are discussing by hand prior to the invention of machines?
I found this in regards to shoemaking in the 1600's "By the 1600s, leather shoes came in two main types. 'Turn shoes' consisted of one thin flexible sole, which was sewed to the upper while outside in and turned over when completed. This type was used for making slippers and similar shoes. The second type united the upper with an insole, which was subsequently attached to an out-sole with a raised heel. This was the main variety, and was used for most footwear, including standard shoes and riding boots."
