This may or may not be what you are looking for, but I wear the $10 off-the-rack sneakers from Walmart. These are the ones just hanging there, not in boxes. They last 3-6 months for me depending on how hard I use them. They remarkably do not retain smell until right before they are worn out, I don't know why. I buy 2 to 3 pairs when I see them - Walmart rarely seems to have my size in stock.
I stumbled on these years ago looking for reasonably priced sneakers, and discovered not only that they cost only $10, but they fit me perfectly without any break-in period.
Just an idea, as I said I'm not sure if this is what you are looking for.
