Snake proof - mostly hunting in Africa takes place in the winter / dry season so snakes are not really an issue. Vast majority of snakes will get out the way in any case, and as a client you will be walking behind trackers and ph. Those brought up
in Africa learn about snakes from a very young age.
Puff adders do like lying on paths and in the sun. Keeping your eyes open and you will see them.
Snake bites tend to occur amongst locals who are clearing bush, cutting timber etc. Cobras, mambas etc attack if you go into their space and are stupid.
Snakes, especially in the winter season do like warmth. Two favourite spots are in the long drop loo, and in your sleeping bag if you are sleeping on the ground. Don’t use a shotgun to deal with a cobra in the long drop, do use a mossy net if camping by the fire - it keeps snakes, scorpions, hyenas, over excited clients and all sorts of other critters out of your bed at night.
In Zambia we just lived in bata boots - suede boots with a flat soft crepe like sole and we walked for miles in them. Never bothered with socks - they just pick up grass seeds.
