It seems to me that there are two schools of thinking emerging. One school says that you should stop heel striking and go straight to full-on barefoot running with a pair of minimalist shoes with no heel elevation.
The alternative school says that moving away from heel striking is a journey along a number of points with gradual reduction in cushioning and heel elevation of shoes where the ultimate destination is barefoot running but you may not choose to go that far.
The shoe manufacturer who most strongly subscribes to the latter school is Inov8. They show this transition through different running styles in the diagram below.

Inov8 are well on the way to having a range of shoes to satisfy the needs of runners looking for shoes with a complete range of options of heel elevation and cushioning.
This is quite different to Vibram Fivefingers and Terra Plana who are much more purist in their thinking. They passionately believe that barefoot is best and only offer shoes with no heel elevation and minimal cushioning.
I don’t claim to have the answer on which approach is correct but I would be interested to read your comments.
