On the topic of Shoe Goo, I prefer Freesole AKA Aquaseal SR. It's made from urethane, so it's a little more flexible and grippy than Shoe Goo. It's marketed as a way to restore soles for hiking boots etc. I find Shoe Goo dries too hard and is not flexible enough, so if you apply it to the bendy bits of the shoe, the shoe no longer creases in the right places, but around the Shoe Goo. If you're real picky (I am), they also sell black colorant that you can add to it, so that it matches black soles better.
