I don't like things I can't repair. One pet hate is those stupid plastics that don't react to any known glue so once broken, can only head towards land-fill.
Another issue is shoes. Occasionally, the sole starts to come unstuck from the top and needs a little glue to fix the join. It was glued originally so repair ought to be easy.
Trouble is, the join has to flex. You can't use epoxy as it's too stiff and after a few feet of walking, starts to break down. Evo Stick, being a rubber glue, ought to be better but never seems strong enough to me. I'll confess that I've even had failures when having repairs professionally carried out. New soles pulling away from perfectly good uppers for example.
A while ago, I bought a tube of Unibond EXTREME glue. It claims strength and flexibility so I gave it a go.
I can report that on one pear of shoes, the join, at the toe, was effective and allowed me to cover many more miles before I wore the soles out. More recently, it's been used to re-fix a boot sole which shows no evidence of glue being involved in the manufacture and this seems OK.
Two tricks: Open the gap with a screwdriver so you can squirt the glue well into the join. Second, a paper towel dampened with white spirit wipes away splurges of glue from the sides, leaving a perfect join.
