The greatest news of all is that these barefoot buddies have, so far, rid me of a left knee strap and right knee support. It appears the theory that running barefoot (eliminating heal strikes) does indeed optimize body mechanics and reduce wear and tear on joints and ligaments. I remember clear as a bell just a few months ago, while still in running shoes, my right knee would begin to ache at 2.7 miles. Each consecutive run shortened the distance until I could barely run over a mile without pain. Today I ran 2.07 miles, it felt great, and I'm very excited. I plan to gradually increase my mileage and as I do, I'll keep you posted.
If you use Vibram running shoes please share your story. I'd love to hear from you.
