I have received some confusing information about hand-welted rubber sole shoes and I wanted to see if I could get a better understanding from the forum. I have spoken directly with Vass, Zonkey Boot, and Ed Et AL and they say they hand welt rubber soles to their shoes. Ed Et Al even does them with fiddleback waists. However I spoke with a craftsman at John Lobb (Jame's Street) and they tell me that they use a Goodyear welt for their rubber soled shoes as it works better. I have also read on the forum that Vass uses a Goodyear welt for their rubber sole shoes as well. Can someone shed some light on if and why rubber soles are difficult to hand-welt? Can it be done well (from the shoes I have seen from Ed Et Al seems possible)?
