FAQ
Does one iON SYNC plug offer enough conductivity for therapeutic earthing?
Our medical grade iON SYNC composite material meets the standards for therapeutic earthing (less than 10^3 Ohms resistance). Any sweat that wicks into the insole expands the conductive surface to the greater portion of the sole, therefore enhancing electron transfer to the foot.
Are the Ion Sync® earthing plugs watertight?
Yes, all the earthing plugs are compression fit into the outsole making for a solid rubber seal. Also keep in mind the tabi shoes feature fabric between the toes which is the most likely area for moisture infiltration.
Can you feel the Ion Sync® earthing plugs underfoot?
If you feel for the Ion Sync® plugs you can feel them underfoot but after wearing the shoes for a while they go unnoticed.
Do iON SYNC® earthing plug contain latex?
No, our iON SYNC® earthing plugs are latex-free.
Will the Ion Sync® earthing plugs wear out?
The Ion Sync® earthing plugs are recessed and sit flush with the outsole tread at the midfoot so they are well protected. Their resilient rubber composition combined with their strategic positioning exposes them to low wear for max longevity. If they do happen to wear out, they can easily be replaced.
