I'd take it to a real cobbler myself. We have one of those here in Chicago that I took a nose-broke Brooks saddle and he glued in a piece of leather under it and made it whole again. I gave it to a friend who has been riding it for the past 6 months with no problems. I'm sort of a clyde so I didn't trust it under my heavy behind. Guy charged me $15 to do the repair. I bet a guy like that -with the right glues, could make those old shoes like new again for $20-30. They have the right glues, the right lasts to put inside of them for clamping, and the experience to know exactly how to do and which specific materials to use in every different case so it stays together.
