I have a favorite pair of shoes.  My left foot strikes the pavement harder than my right - wearing the left outside of the sole down.  There used to be a shoe repair a block away but people have gotten used to "discard - able" fashion.  I don't want to discard these shoes so I thought I'd try Shoe Goo to rebuild the area I destroy.  I've only put one layer down so far and it has helped.
I'd like to put several more layers down to level the area.
It's really easy, cost efficient and helpful.
Shoe Goo isn't just for re-gluing areas - it's great to rebuild worn down areas.  You Tube has excellent videos to help.
I'd definitely recommend this product.
