My rubber boots always end up cracking on the back of the heel. I've tried sealing and patching them with every kind of adhesive I could find. I've used tire and vinyl patches and sooooo many different adhesives. I've found they're either too brittle and just crack or they peel off like the shoe goo on yours.
If you find an adhesive that sticks a little better than others, try roughing up the surface of the boot, so it can stick even better. I had one patch that lasted about a month once I did that. I tried so many different adhesives that, I'm sorry, I don't remember which one worked the best anymore. I eventually decided rubber boots are just going to have to be consumables for me.
Once they crack, I cut the tops off and use the foot part as waterproof clogs until they meet their end in some way. The tops get stashed away for patching things or resoling slippers.
