I know quite a runners who have different factual data. maybe I should bring up Joan Benoit Samuelson who runs 12 miles a day for over 40 years all in Nike's and never had a knee, leg, back, foot problem.
Look up Born to Run.
But no really, the human foot is designed to run, it's designed to shock absorb on its own and it certainly doesn't need any help, you are supposed to run with only the front foot touching, just like the sprinters. When people wear running shoes, almost everyone touch with their heels when they run, which doesn't give the same support. That gives hard impacts on each landing all the way up, through the ankle, knee and hip.
Yeah sure, there are people who doesn't get pains, but that doesn't mean that it's an optimal way to run.
Barefoot is the way, or if the surroundings demand it, some kind of protection against glass shards, sharp rocks etc.
