Running Barefoot Is So Easy a Caveman Could Do It
Neglecting to make any apologies for possibly offending the caveman community, Dr. Stuart J. Warden, an associate professor of physical therapy at Indiana University, gave a cutely titled presentation at the American College of Sports Medicine in Denver: "Barefoot Running: So Easy, a Caveman Did It," playing off an ongoing comedy line on American TV's GEICO commercials.
- Start by taking off your shoes and simply standing on sand, gravel, grass, or unpainted concrete. All of these surfaces, experts in earthing tell us, transmit the healing frequencies of the earth. If you don't have the energy to stand, at least sit down with your heels and hands on the ground.
- Simply relax and enjoy. The earthing experts will tell you to do a guided meditation to let your mind clear while your body absorbs the energies of the ground, but it does not have to be even that complicated. Simply let the earth do the work.
Here are 10 reasons you should start running barefoot:
1. Barefoot running as a moving meditation
Barefoot running, for people who learn to do earthing, becomes a moving meditation of catching something similar to musical notes from the earth's frequencies. Moving the foot off the ground creates a kind of energy silence while placing the foot back on the ground creates a staccato of earth music.
But let's suppose you just aren't into any health practices that are quite that "natural." Are there any other aspects of running barefoot that are positively healthy?
2. Barefoot running decreases forceful impacts
When runners run barefoot, they run on the balls of the feet or the middle of the foot. This way barefoot runners avoid forceful impacts, equivalent to two to three times of body weight.
3. Barefoot running can be comfortable
Yes, barefoot running can be comfortable, although most people today think barefoot running is dangerous and hurts. However, you do need to prepare your feet for this rebirthing experience and start run barefoot on the world’s hardest surfaces without the slightest discomfort and pain.
4. Barefoot runners have different striking pattern - they point their toes more at landing and minimize forceful impacts on their feet
Barefoot runners do not strike with heels and they point their toes more at landing, avoiding the collision effect. This way they decrease the effective mass of the foot that comes to a sudden stop when you land. A consequence of barefoot running is more compliant and springy legs. That's a good thing. 
5. Running barefoot improves balance and proprioception
Running barefoot may improve balance and proprioception by activating the smaller muscles in the feet, ankles, legs, and hips that are responsible for better balance and coordination. Although an 8-week research didn't prove statistically significant changes, researchers do not exclude possibility that it may take months or years to observe positive changes. 
6. Running barefoot reduces tension on the adductor musclesThe adductor muscles help the lower half of the body move "outward." The adductor brevis muscle helps us move to the left or to the right from the hips. The adductor magnus muscle helps us move to the left or to the right from the thighs. This is the muscle involved in pulling a hamstring. The adductor longus muscle helps us rotate the femur to the left or to the right.
When these muscles don't work properly, the body tries to turn left or right from the knees rather than from the hips, increasing risk of knee injury. Toning these muscles is one of the ways barefoot running helps prevent knee injury.
