Hi,
most cobblers / Orthotic companies seem to use Renia glues. However as industrial glues that start off in 1 litre containers.
They do an impact adhesive shoe repair glue called ‘Klebfest’ in small tubes which may do the job.
make sure both surfaces to be bonded are free of any dirt etc and roughened up. Then press with as much pressure as possible.
There is also a German company called Extremme textil that sell Vibram rubber sheet.
Hope this is of some help.
