I've been reading websites such as barefooters.org and barefoothikers.org because I really have loved the times that I go out-and-about barefoot.
I've also found that there is a small school of thought that says that our feet have evolved over millions of years to function properly and we are messing them up by wearing shoes. (Read some of the article snippets at this link: http://www.barefooters.org/medicine/). Some of these studies suggest that shoewear increases ankle injuries, etc. Also check out http://www.unshod.org/pfbc/toysaw.htm and other information on that site.
I am by no means a doctor, but this way of thinking makes sense to me.
There is also a company "Terra Plana" that makes eco-friendly shoes (some completely from recycled material). They have a line called "Vivo Barefoot" that has a very thin, flexible Kevlar sole that supposedly makes you feel like you are walking barefoot (but still have the social advantages of wearing a shoe). http://www.terraplana.com/vivobarefoot_info.php
Thoughts anyone?
