My latest epiphany:
I can apply Shoe Goo to the soles of my athletic shoes and house shoes when the soles start getting worn down thin, *before* any holes or cracks develop. That way I don't have to fill up all the inside of a hole with goo too, which besides requiring more goo to make the repair, also makes the shoe heavier. By hole, I mean the empty spaces on the inside of rubber soles, which many athletic shoes have, and which become apparent once the outer surface of the sole has worn away.
