J-B Weld. Easy to find stateside, no idea about in Norway. Might as well try, you have nothing to lose.
Or Barge Cement, also sold as E6000.
But more importantly, high five for destroying sports equipment.
Thanks biggins, I'm learning from the best!
Yeah, Barge Cement would also be a good choice. .J-B Weld is a kind of epoxy, though others could also work. Don't use the quick curing stuff (5- or 12- minute), choose the heavy duty kind that takes hours to cure.
Oh. I went to a store that the internet said would have J-B Weld but they didn't so I got some kind of 2-part epoxy that had a picture of a shoe being repaired on it. And also "5 minute setting time". Hopefully it's good enough for a shoe that is only used while riding a bike. Presumably that's a lot less stressful than a shoe used for orienteering in Norwegian forests.
You could try it, but I'd save it for household repairs and hold out for better stuff for the shoe.
