realise that in our part of the world (i'm from singapore) you often find the indigenous people walking around barefoot thru the jungle too! doesn't mean that I'm willing to do the same.
these people grew up in that sort of environment. we would find walking barefoot thru the underbrush terrible.
trekking sandals though are another matter... if the vegetation isn't too heavy and the area really is too wet, a pair of TEVAs might do the trick... if you're not concerned with the bugs and the many times you could stump your toes... and the thorns... and all the little twigs that get in under your foot and poke as you step hard on the insole...
I for one am a clumsy kinda walker... I kick tree roots, rocks and whatever else that sticks out of the ground all the time. In a forest, my toes would be a mess if I walked around in just sandals... I'll opt for boots.
Sandals are "camp" wear for me... like when we've reached a nice spot where we might stay for a day or 2... I'll break out the sandals. But if it's just an overnight layover with more walking to be done the next morning, I wouldn't bother taking them out.
I'd also like to volunteer something else about rubber boots (galoshes, wellintons) or canvas shoes or thongs (rubber sandals, flip flops). As DE-SO mentioned, economic factors are often the driving force behind the choice of many locals when it comes to jungle footwear... Another factor is that for them the jungle is in their backyard. They (some of the malay villagers I have observed) go into the jungle to forage whatever they need, it's like going to work... they don't live for several days on end in those same rubber boots. If they did, their feet would rot just the same as the rest of the gringos' too!
I think the whole point is that if we're trekking/hiking in a jungle environment, you HAVE to take your shoes off at the end of the day and give them a chance to drain. You HAVE to take them off or your feet WILL rot!
Oh, and liberal applications of powder. I use the military surplus ones which are "supposed" to be anti-fungal and anti-bacterial. Powder before your put your boots on and powder after you take them off...
On a tangent, my army boots have a removeable plastic insole that seems to be made from several layers of fine plastic mesh. LOL if you hold them up to the light, you can see right thru the small holes. They really do not hold water at all... You could walk out of a swamp, unlace your boots and por the water our and fling the insole and it'd be dry (at least not soggy). The leather of the boot and your socks will of course drain water back into the boot as you walk... but you can repeat the exercise again later on! is anyone familiar with the name of these insoles??
