This is fascinating.
In my youth I used to run long distances barefoot, so I was running on my toes. When I started using running shoes, they were basically a very thin leather sole and lightweight upper. Again, on my toes.
I stopped running for a while, and when I picked it up again, the modern running shoe was the hot thing, so I went along with that. My normal run was about 6-10 miles offroad and the shoes forced a heelstrike method which by then, I believed was the correct way to run. Unfortunately I have flat feet, so after 12 years of running heelstrike, I gradually gave up because of foot pain in the mornings.
In retrospect, it's obvious our bodies are designed for toe first because early man didn't have thickly padded shoes, and running heelstrike on hard surfaces is painful very quickly.
I'm all fired up to running another go – so what shoes for toefirst running?
