A friend has asked me to mend her walking boots - see photo
As you can probably see from the photo I've peeled the heel off as rather than being solid rubber it's got a core of foam. The foam core has started to disintegrate. If you put it all back in place it looks great but of course is not wearable.
I've said I think it's hopeless but have offered to have one last go at a repair.
I'm thinking of trying to solidify the disintegrating foam core with a generous application of Gorilla Glue then glue the rubber edge back to the upper with some high viscosity superglue.
Any other ideas?
