While the concept of earthing and grounding is age-old, the application of it within shoes is far more recent. In practice, combining this idea with a well-made, supportive shoe has shown to significantly refresh worn out, tired feet.
1. Why is copper used in grounding shoes instead of some other metal?
Juil uses copper in their sandals to create an avenue of conductivity between the earth’s surface and our bodies. These copper points act as a conduit that helps our bodies stabilize our physiological frequencies.
As Juil mentions, the reason for using copper is two-fold:
1) Conductivity – for any shoe to be considered an earthing shoe, it needs to be conductive. That is, it must allow for a direct connection between your body and the earth so that electrons can make their way into our bodies from the earth.
2) Malleable – Being a highly malleable (or soft) metal, copper is more easily shaped and placed in the shoe.
2. How many points of contact do you need to maintain an earthing connection?
Just one! Only a single point of contact between your feet and the earth’s surface is needed to maintain an earthing connection. (But it doesn't hurt to have a few extra.)
3. Are Earthing Shoes the same as Minimalist Shoes?
Not really. As Juil explains, barefoot and minimalist shoes are great for those people looking to walk and run using something on their foot that mimics the true posture/gait of a bare foot. Earthing and grounding shoes are meant to offer a direct connection with the earth to use the earth’s free, natural healing power in the form of electrons.
