http://www.trailcast.org/programs/16 This is a link to a podcast where they interviewed Jackrabbit and Isis, the Barefoot Sisters. They've attained notoriety by hiking the Appalchian Trail barefoot! Over the course of 15 months, they hiked round-trip without any shoes, except for sometimes in boots to protect them from frostbite in the winter months. It's a really great article...the interviewer is genuinely impressed with their achievement, and it's a really positive pro-barefooting discussion!
