Be a real man and go barefooted. ;)
All joking aside: I'm in a warm part of the country and always wear a minimalist "barefoot" running shoe. These minimalist shoes protect your feet from cuts and provides traction. But, beyond that - your feet do the work. The muscles in your feet will strengthen and you will have healthier / stronger feet.
As a bonus: They dry very quickly (even while I'm wearing them) so I never stress about walking thru water. Also, no nasty socks while camping!
I get cheap ones for $25-30. They last about 1 year. Not very long just because they are so thin. But, they are cheap enough I don't mind replacing.
These are my go to river toobing shoes
