Your feet have been in solitary confinement most of your life.
Sure, your shoes protect you from broken glass and icky bathroom floors.
But what about your evening walk? Checking the mail? Walking around the house?
By going barefoot, you reawaken nerves and muscles that have atrophied from years of your shoes doing all the work. Think of barefoot walking/hiking as free reflexology; the pebbles and cracks in the ground stimulate nerves that help lower inflammation and blood pressure.
Ditch the sole and awaken the soul!
