Take off boots and socks, slip on Crocks. Change back after the crossing.
Have done that. Crocks were so slippery that I have to use a walking stick to be sure not to fall down in mid stream.
I have worn wet boots but prefer to keep them dry, so more usually have stripped down and waded barefoot.
In a week long backpack hunt with two waist/chest deep river crossings, I bought a cheap pair of vinyl chest waders, took them on the float plane, carried them miles in my pack, and they split out an inseam when the water got about to the bottom of my ribs.
