in the tropics? the word is... flip-flop! It's great to have a good pair of boots, but even better to have a pair of boots and flip-flops. The best situation will be two pairs of good boots, two pairs of light fabric sneakers, and a pair of flip-flops. You're gonna wanna change those suckers every chance you get. You need to dry your feet out every couple of hours or you'll have a case of athelete's foot sooo bad that you'l consider cutting your feet off. Lots of foot powder and stuff for jock itch too.
