My podiatrist told me that aspiring barefoot runners make up a large part of his clientele, and in his professional opinion this is a dangerous errand. People who were running barefoot since early childhood (including various native peoples of the world) maybe fine because they spent formative decades of their lives acclimating to the style and growing stronger muscles/ligaments/joints/bones/skin, but everyone else is running a high risk of sustaining an injury (and enriching my doctor in the process).
Vibran Five Finger was targeted by a class-action lawsuit stemming form lack of scientific proof of their barefoot claims, and they settled. Vibram stood to gain a lot from showing the proof, and the fact that they didn't have anything convincing on hand is quite damning.
High risk is obviously not certainty, and people who did derive benefit from the method are likely to speak up, while those who failed are likely to have moved on and say nothing. Survivor bias alert.
Barefoot running has a strong "appeal to nature fallacy" factor. Doesn't make it wrong, but this sort of bias should be noted when calibrating the level of excitement for a particular subject https://en.wikipedia.org/wiki/Appeal_to_nature
If you're gong to do it anyway at least consult a podiatrist about early sign of trouble so you know when you're going down the wrong path. This would be way more useful than acquiring your advice from various internet forums.
My doc refused to answer the question about safe running techniques and told me to get a bike instead. Which I did.
