You may want to try running in racing flats or even bare foot on grass or dirt. You will immediately get the feel of what is being marketed as "POSE" method.
Everyone runs with a mid/fore foot strike when barefoot. Most modern running shoes have to much heel lift which forces a heel strike on impact. The force is dissipated by the shoe padding but it is not as good a shock absorber as what God gave us, the elasticity of the tendons in the foot and heel. The old waffle trainer was probably as good as running shoes ever got.
Some shoe companies are rethinking the heavy padding in the heel area. If your looking for a good trail shoe check out inov-8
