Listen, go to a reputable running store with the ability to do the aforementioned analysis. While I normally would never disagree with Jake Di Vita, I will on this. We are not Kenyans, in our society we (most of us) grow up wearing shoes. As a result the musculature of the feet in most Americans is not as sturdy as someone who has gone barefoot thier whole life. Pounding your feet in a pair of Nike Frees is not a good idea for your feets sake.
What is a good idea is working up slowly in your mileage, no more than 10% additional mileage added in any week for a long time. Then, when you are fairly healthy and running regularly you could work in the Nike Frees at the end of runs. I would not run more than a 1/4 mile at one time the first several weeks. This will allow your feet to build up the musculature and strength needed. At some point, with the proper break in/build up of your feet, you may find that the Nike Frees are for you and that is all and well. After all the foot is designed to be barefoot, unfortunately we usually limit its strength by wearing shoes. Going all out free/barefoot can be too much strain all at once for some people.
Being an on/off again runner and with children that competed in track/cross country I can say that the whole Barefoot/Nike Free craze caused many injuries and lost races/training for adults and kids. My own daughter lost an entire Cross Country Season because of this. The above is my research and the answers I got from the Doctors who treated her. I should say that she was at 35 miles a week and free of injuries until she did the Nike Free/barefoot mile. In one slow mile cooling down she ruined her arch and her season.
I'm for the Nike Free/barefoot crowd, just know that you probably need to build your feet up very slowly over several months to avoid the inherent risks invoved with jumping straight to Nike Frees/barefoot running. IMHO
Good luck, experiment, pass knowledge!!
