I run on the forefoot, an artefact of my boyhood living with a father who did shiftwork. You literally tiptoed around the house, unconsciously and in the end quite quickly. The movement patterns persist.
I got into the forefoot/heel debate some years ago, motivated by what I now see was a need to feel a bit superior. It's a harmless urge, but in that context was a bit silly. People run how they run. But I did a lot of reading at the time, and it is still notable now the debate seems over how the two styles are quite different biomechanically. This is especially so with the eccentric loading of the calf complex.
I myself, when I give heel striking a go (and I heel strike when running in heavy shoes, for example in work shoes running for the bus) am acutely aware upon footstrike of there being nothing between my knees and the ground but a column of bone.
It follows if I ran heel first I would compensate elsewhere in the kinetic chain to smooth the ride. But as it is, my teeth rattle and I'm not sure how you 80 per cent of other runners, most much faster than me, possibly do it.
But then, the movement patterns came from trying to move silently over floorboards as a kid, where heavy heels bought a heavy penalty
