you're supposed to use Evo for that but I keep thinking 2-part resins
are stronger. The Evo seems to work off after a while, although the
5-min araldite I'm using isn't a lot better. So I was hoping stronger
araldite could do the trick.

It's rigid, and the bond will fail quickly. You ought to buy some
shoe glue (polteurethane with toluene solvent).
