While in Tanzania, my friend really took a liking to the "tire sandals" that many Masai men wore. It turns out you can buy them at the local markets. about 15 minutes to get a custom-made pair. 20,000km tread life warranty 
Like any good shop - you get to choose your model.

While they may be what the locals wear, they sure aren't what the outsiders wear - no cushioning on the sole and no arch support. On top of that, they don't get many mzungu at the local markets. Lucky for us, our guide was from the area so we stopped in and did a bit of shopping. Most people just whizz by on their way to see the animals.
It really makes the trip a great experience.
