Regular super glue (stuff you usually find in those little bottles) is actually incredibly effective and worth a shot if you can't find something even better. I used to have a pair of tennis shoes that were my favorite for some darn reason, just couldn't bring myself to get rid of them. I had them for something like 8 or 9 years, so naturally the soles wore until they were breaking away from the shoe bottom. A little bit of super glue later and they would hold together for another solid year before needing any more. Yes, I have since bought new shoes. lol
