What glue to use in Rock boots

[oldtimer]

I was in the shoe business for too long.  One option would be shoe goo.  Another would be good old Barge cement.  The latter can be had from a shoe repair place.  Just make sure your rock boots are completely dry before doing the repair AND make sure what ever fix you use has enough time to cure before jumping back in the water.  Oh and make sure there is no sand or other contaminants that could compromise the repair.
