What I've learned about gluing blown out footwear over the years is the repair is good to get you through for a few days till you can get to a store and replace them.
That said, I bought a pair of water shoes, basically a spandex sort of mesh with tacky gel soles. I bought them for kayaking and launching the boat actually but have used them in rivers and ponds fishing. The inner liner came out a few years ago but the soles and outsides are still well in tact, so I keep using them. I thought I was getting screwed paying $12 for them, now I wish I could find the exact same ones again. You look kind of like a fairy walking around in them though but at 66yo, 6'2", 230lb, with a gray beard and fairy shoes and ball cap hat ? Well, obviously I really don't care what anyone thinks anyway.
I won't wear anything open in a rocky river though or even these soft sided water shoes. My wife won't either, she finally learned about that. Shorts yes, open toed or soft sided shoes no. Those rocky bottoms don't budge and can be sharp ! But around the Cape it's mostly sand.
