Wikipedia is a user edited site. in the past I have found that the pro-barefooting/anti-barefooting feel of the site can vary from time to time. A while back I edited the Physical education page to include some information supporting the use/encoragement of bare feet for children takeing PE. The information I included was more reflective of the UK approch than the US approch. I went back a few weeks later to find the someone had removed all refrences to barefoot related health benefits from the page.
The moral of the story is:
Don't get too excited by a pro-barefoot artical on Wikipedia, because a shoddie might delete it tommarrow
