Who does not know - just the favorite shoes get broken! For me, the sole of my summer sandals solved. Sure, you could go to the shoemaker, but that's expensive! So just checked, which could be suitable adhesive.
The shoe on the packaging makes it easy to find this adhesive. And just as easy is the application: gluing squeeze, (I've taken small Minischraubzwingen and tuned for 24 hours) and even the shoe is like new again!
