I've used a wide variety of different things on my feet over the years:
I suggest that you just go for a pair of river-shoes.
They're designed to fit well in the boat, shed water well and grip terrain.
I have
these I'm perfectly happy with how they perform and they weren't too expensive.
RE socks:
I'm sure that they all do the job they're designed to do perfectly well.
I've had the peak ones and the palm ones, I was happy with both, probably a bit happier with the peak.
With constant use you're probably going to wear holes in them in about 6 months or so regardless.
I'm on pair 6 or 7, but I use them for a lot of different things.
