While the author may not have intended a discussion on what it means to barefoot, it sure seems to be important to people. I'm sorry for throwing people off the author's topic.
Due to the use of the phrase "barefoot running" when people are wearing some form of foot wear, some individuals have coined the term "naked foot running" to differentiate between the two types. Your either barefoot or your not.
I started running back in 1995 when I joined the US Navy. I never really enjoyed it and went through bouts of shin splints and PF. BF running changed running into something I enjoy and I have remained injury free.I hate the times I have to wear shoes.
