> The best endurance runners run in such a way that their feet land on the front of their foot during running
This is not really true and the whole fore foot vs heal striker thing is a bit of a red herring. There are elite distance runners that are forefoot, mid-foot (probably the majority) and heal strikers. The main thing is that wherever on their foot hits first, the foot itself is under their center of gravity and not out in front of them.
Yep, over striding is the problem in many cases.
