These Flip-Flops Promise to Make You Feel More Calm, Energized and "Grounded"--Really?

Is there really such thing as a pair of flip-flops that can make you feel calm, energized and less achy all over? Can a sandal change your life? 

Remember how good it felt to be a kid and run around barefoot outside in the summer? Well, that's the whole concept behind a new health movement called "earthing" or "grounding." Proponents say that the more time we can spend barefoot, the more we soak up the earth's essential energies and feel-good vibes. (I know, it does sound a little out there, but stay with me here.)

Enter a new line of shoes, well, flip-flops, called "pluggz" and here's how they work, according to the company's web site: "Each pair contains black plugs made from a custom carbon and rubber compound that sit under a weight bearing part of our feet ensuring electrical contact between the earth and us. These plugs are designed to conduct a flow of free electrons from the earth to our bodies. This proprietary technology allows us to get grounded when we walk on grass, sand, soil--or even concrete."

OK, so how is grounding supposedly good for us? "People say they feel better when walking barefoot on grass or sand or earth. According to modern science that’s because being barefoot enables the body to efficiently absorb earth’s abundant electrons. The very same electrons that make us feel good. Traditional shoes interfere with this absorption. Not pluggz. 

Every pair of pluggz has a black plug - the round circle towards the front of the shoe, beneath your metatarsal that is particularly adept at allowing the free transfer of the electrons, naturally giving your body what it needs to help heal itself, and stay balanced and happy. ... As you wear them you’re likely to start feeling what other pluggz wearers have reported feeling: more balanced, more energized, a sense of well-being, or calmer or fewer aches and pains."
