Looking into this a little more, it seems like the reason molded or "bonded" soles, as apparently they are called, are difficult or impossible to repair because removing the old soles also damages or destroys the leather part of the upper shoe.
If that is the case, I wonder if you could cut off most of the existing sole, then construct a wooden heel with a recycled rubber (tire rubber or other) tread, and then either nail it on or use the same type of cement the shoemakers use to attach the new soles. Chances are it will look a lot sloppier than a pro job (at least it would if I did it) but it could prolong the life of your shoes.
