I edited my post to make it extra confusing. You're welcome.
I have used those, they work as well as any of the thin, overboot "waders". They will last a lot longer if you don't wear your boots in them, and instead use them like wading pants. If you fill them up with water, they really suck, and if using as mentioned, they will pop the crocs off your feet before you can say whatever choice word you were looking for.
The wading pants don't go over the boots, you have to pull boots, put on wet pants, then stuff feet into crocs. Its a production, but its a lot more protection too.
