I asked a similar question last year ahead of my trip to the Amazon in Peru.

Rubber boots are the best option. Most people in the Amazon use them: safe, cheap, easy to wear.
My feet cannot bear them; too hot for me. I find desert boots the most comfortable; they protect from animal bites, thorns; allow transpiration better than average shoes; get dry quickly. But you have to take care in choosing the right model, as per the U.S. Army specifications. With the complication that they have been and are produced by many different firms and there are differences even among lots of the same brand! Soft and foldable in the upper part; with big open diagonal grooves in the soil; laces running through metal rings with their axis parallel to your legs (rings in normal shoes are perpendicular to the skin). almost 2 years agoAnswered by Carlo Castellani via WorldNomads.com
When I first purchased these boots, I never looked back. I live in an insanely hot desert and have trekked in Asia's jungles, not to mention did a bit of a walkabout around the EU.
