The fabric on top of my loafer's insole has been coming loose, so today I decided to try and reglue it. And what better than super glue? After I finally got the clogged lid off of the tiny tube, I squeezed glue generously onto the rubbery insole, and… it got hot and gave off some fumes (probably toxic). Perhaps this will contribute to a stronger bond.

Update: the bond seems to be holding well.
