well to answer both these.... the rear is useful, but not metal, the original question related to metal. use rubber/plastic. which is what b. nelson recommends.for the second one, my john lobb rear rubber portion are noticeably more durable than any other shoe i own. for what reason, i don't know, but i work them for two weeks regularly before having nick put on rubber taps and you can't even tell they were worn.
