A decent pair of shoes ... built well enough to not break apart at the seams ... even if it cannot be resoled CAN have a half sole glued onto a wearing out sole, and probably a new heel put on, remarkably extending their wear life.
Oooh, I didn't know that. I do know of a cobbler in Stamford, CT. I might stop in with the pair of shoes and see what they have to say about replacing the heel.
