“What other animal in nature runs on their heel?”
Dog, horse, cheetah, deer, lion…they all appear to run on their heels like we do. But then of course they all have four legs. Now I don’t think I’ve ever seen an ape run for play or hunting.
The majority of professional runners heel strike too unless they are running the 100.
The problem isn’t heel striking, it’s overstriding

Other top distance runners who don’t heel strike: Paula Radcliffe, Kara Goucher, Mo Farah, Meb Keflezighi, …
The Brownlees also run with a mid-foot strike, as does Mirinda Carfrae. There are many, many more.
Also, Usain Bolt doesn’t magically change his stride when he runs the 200m.
However, I agree that overstriding is the main problem. Heel striking is often a sign of bad form, including overstriding, but isn’t necessarily the problem. Having said that, it’s very difficult to overstride if you land on your mid-foot. I think the point here is to let the landing come as a consequence of the stride - fix stride and posture and the landing will come. “Fix” the landing without changing anything else and you’re asking for trouble.
(I’m not going to spend any time on the animals running except that the structure of the foot means that they all run and walk on their toes – http://en.wikipedia.org/...tive_foot_morphology)
So when I get home tonight and get to view youtube (I can’t at work) you are sure that I’m not going to find a video of any of those people heel-striking?
Seeing your reply to Devlin, you’ll disagree about Meb for sure. The rest I’m pretty sure about. Of course, I can’t speak as to what you’ll see in the video, just what I see in the video.
