From my own experience I have found that barefoot running and minimalist shoes( less cushioning) have actually helped me go from a "crocked" runner who was see a physio every week who was trying to sort out my IT band, knee & achilles problems to someone who is now running most days.
It is claimed that when we run were landing with between 10 to 12 times our body weight.
No small amount of EVA, GOO, AIR, SPRING is going to absorb enough of that shock to make a significant difference, what comes into play is your muscles, the arch of your foot, tendons, ligaments etc.
Get the basics working right and strengthen your feet, ankles, calves, quads, hamstrings.
