Just wanted to recommend this site as alternative footwear to the Vibram Five Fingers:
Moccasins have been around for ever of course, they protect your feet and do so in way that doesn't prevent natural foot function like regular shoes. They worked for Native Americans for thousands of years!
I have no financial or personal stake in the above company. Just a big believer in primal living and wanted to share something I thought others members might enjoy as well.
I want to get a pair of these made one day: http://www.russellmoccasin.com/
