No need to overthink the boot thing!
I will be going back to Africa the 4th time, this August. Will be wearing the same Keen Targhee II boots I wore three trips and 10 years ago, and on nearly every hunt since then here in the US. Just make sure whatever you choose is broken in and comfortable, as you will be spending a lot of time with them on your feet.
I'll second this. I took a nice pair of Filson Bird shooters over once...NOT the right boot! Comfy but made me sweat. Now I use uninsulated Danner boots ( the kind the military uses) They breathe and they are very comfortable.
Many times in Africa I just wore my running type shoes, sometimes sealing the tops with duct tape to keep seeds and thorns out, real classy, but it worked!
