The classic advice which will always ring true, forever and ever amen, is to have dry, good fitting socks. If you submerge your boot in water, walk for a while to dry them out a little, then change your socks. You should be fine after that. I recommend some sort of jungle boots since they dry out faster. Especially the ones with those little vent hole thingies on the side for spilling water out of.
The other strategy is waterproofing your boots, which works to some degree, but I've never personally had waterproof boots stay effective for very long.
My personal strategy (utilized for multiple month long hikes) is to have a pair of boots, a pair of good sandals, and at least 3 pairs of socks. I rotate the socks out daily, and if I ever run into the problem of all my footwear being wet, I wear the sandals to keep my feet open to the air. I've never really used foot balms or powders, so I can't attest to their efficacy. Use moleskin for blisters, or just walk around barefoot on your driveway a bunch to toughen your feet up more.
Remember, trenchfoot can set in in as little as ten hours.
