My wife's boot heel is worn through the rubber to the leather.
If I replace the last layer of leather on the heel (it's pretty
thick as there are about 10 layers, so I'd guess 1/8th inch)
and the rubber pad, I'd be a hero.

Where can we mail order this thick boot heel leather and
rubber pads to cut to size?

Any experience repairing boot heels?

Have you tried Google?
