Shoe goo will disappoint, I guarantee you. Try a product called Aquaseal..more expensive but it works great in those type applications.
This ^^^
Shoo Goo has been a temporary repair IME.
Aqua Seal is NOT like a $3.00 tube of silicone caulking.
It is expensive and once opened you may as well use it all.
(it doesn't keep well after opening)
I never use the catalyst.
Aqua Seal is recommended (used) for the repair of the most expensive waders in the world because it works.
