My basic foot regime when I am in the Jungle of North Queensland and Malaysia is to wash them at night, dry them with a good scrubbing between the toes and then use the "Foo Foo" bag technique. So 600ml of Johnsons Baby powder with Corn starch in and poor in a bottle of medicated talc, any generic brand from over the counter, to mix up with the baby talc in a 5l dry bag. Put your whole foot in an seal it above the ankle. Give it a slap and rub it in to your foot. It covers your whole foot and you don't leave much if any ground sign of powder. Put your foot in a seal skin sock to sleep in your hammock. Ive had a bag full for 2 years and not run out yet and just top up if needed. Works a treat.
