I gave up traditional running shoes more than 2 years ago and there is no looking back.  Since the first January of 2013, I have only used my running shoes a few times.  Most of my runs have been in my bare feet.  It's almost surreal because running barefoot actually feels normal.  Sure, there have been some issues running on the hot pavement where I have blistered the bottoms of my feet.  If I were running on grass or a trail, this never would have been an issue.

I don't have to deal with plantar fasciitis foot pain any more.   I have been injury free for 2 years.  It sure feels good to be able to hit the trail and not experience any pain.

Original Luna Sandals 

I don't advise starting out running in your bare feet.  Rather, use some running sandals such as Luna Sandals made by Barefoot Ted.

Original Luna Sandals w/ ATS Laces
Bare Foot Ted help start the move towards running barefoot. He is kind of a legend in the barefoot running community. Christopher McDougal gave him excellent press coverage in his book "Born To Run". About the same time the book became a best seller, Ted started making and selling Luna Sandals. Luna's are designed on the somewhat famous Huarache sandals worn by the Tarahumara Indians of the Copper Canyon region in Mexico. Huarache sandals are super comfortable. Your feet are bare with the exception of the bottoms where you need the most protection. Luna sandals are beautiful and look like a work of art when you buy the models with the leather foot bed.
