Saw a middle age guy finishing his run at a local park and he was running barefoot. I askd him about it. He said he's done all this runs barefoot since last spring and it works great for him. A few minutes later he revealed he was out for 8 weeks last fall with a stress fracture in his foot. I guess he had rose colored glasses on.
Here is my take on barefoot running.
I totally get that humans were designed to run barefoot and did for thousands of years. I can understand the attraction that has for some people to want to return to that. But if you want to retun to that I suggest the other following this must be returned to as well.
1) Return to a diet that has your body weight at it's designed weight, not some inflated weight brought about a life time of pocessed foods and chemicals. The guy I talked with was easily 180+ pounds at 5'8" tall, probably 50 heavier than his ancestors when they ran barefoot.
2) Have lived your life without playing soccer, basketball, football or other games that ruin so many peoples knees and ankles. Old injuries from these sports are killers of efficiency for your stride and ability to run "naturally" barefoot.
3) Run only on dirt and grass, that is where we were designed to run. I can guarentee you when our ancestors ran barefoot it wasn't on pavement and concrete, it was through fields and on trails.
But rather than think logically through this, barefoot runners, like the guy I talked to, insist it's natural to run barefoot. Ufortunately he conveniently forgets it's not natural to run on concrete/pavements, to run at 50 pounds above his ideal running weight, or with his bad knees from his days as a football player.
For those of you who can't do number 1,2 and 3 above,I suggest wearing shoes.
