We always get people contacting Juil asking the big question – how do Juils work?
For those that aren’t familiar, Juil sandals are based on the concept known as earthing. When your body is barefoot (or in direct contact with the earth), you’re able to absorb a TON of electrons. These electrons work as free radical-fighting antioxidants. By neutralizing your body’s free radicals, studies suggest you’re able to dispel free radicals and, as a result, eliminate some inflammation and stresses from your body.
But the big question is, how do Juil sandals and shoes work? What is it about the copper that makes them different from other shoes?
By placing copper dots in our shoes, Juil shoes create a direct connection between your body and the earth’s surface. The copper, which goes all the way through the shoe, is a conductive material which allows for that natural flow of electrons between us and the earth’s surface.
So, how can we make sure that Juils are “working”? What measures can be taken to ensure that the “earthing” side of Juils is putting you in touch with the earth?
At Juil, we test all of our shoes for conductivity to make sure that they serve the earthing function they were created for. We do this using two tools:
1) Earthing tester
The voltmeter, in particular, has been referenced and used in earthing studies for measuring the voltage of one’s body as it’s compared to the earth. Here’s how it works:
One lead is hooked up into the ground (0 volts). We measure the difference between that lead and the conductive portion of the shoe when stepping on the earth. Doing so, we see the voltage get down to nearly zero (usually around .08 - .15). Wearing insulating shoes, however, usually sees a voltage range of about 3-4.
We also test the resistance by touching one lead to each side of the copper in the shoes. Again, we see the resistance and voltage get down to nearly zero.
If any of our readers have any questions about this process, don’t hesitate to reach out – we would love to hear from you and answer any questions you may have.
