Cool water kayak fishing - dry & warm feet Q

[Jeffonc]

What are paddlers doing to keep feet warm and dry?. I used the neoprene socks last year. They worked pretty well alone and in combo with the wetsuit, but they seem to have lost all ability to withstand moisture after a year (is that typical neoprene degradation?).

I can switch to waders, but a lot of the season that's warmer than I want to be for the air temps. Looking for a way to keep my feet warm and dry with some expected exposure to the water for launching, shallow wading, etc... with/without waders and wetsuit.

Any such thing exist?
