TANZANIA, TANGANYIKA: Life out in the bush in Tanzania can be dangerous. But it's not just the wildlife you need to pay close attention to. Little cuts and scrapes from thorns and branches you step on can seriously mess up your foot. It's also super painful. I stepped on such a thorn on Zanzibar and it went straight though my thick running nike shoe (the heel to be precise) and deep into my foot. The local Masai tribes however have come up with a solution for this: make shoes from old car tyres. These shoes are not only super durable. They last for decades according to the people I've spoken to who've grown up wearing them. But they're also super strong and nothing that's grows out in the bush will be able to pierce through your car tyre shoes.
