I think you need to give the article due worth, (it was published).
The Rolling Stones sang about wiping shit off their shoes, they were actually referring to those pesky electrons, but they couldn't get words to rhyme with electron ...(go on, you try)
I'm a fan of building foot intrinsic muscles to maintain the arches of the foot, and there is a ligament in there called "spring ligament", it stretched in the stance phase "foot flat", and provides power for the toe off phase, and shoes with fantastic orthotics mean this ligament does nothing.
Bare foot running, or even better, a fast walk on a soft surface can ignite the electrons within the ligament, no, I can't go there even in jest, anyway provided you've got a workable arch structure it will be maintained. Generally people tend to pronated sloppy fail grade biomechanics and decide to wear good fitting shoes.
That Dr Mercola sounds like a real (insert derogatory remark here).
I'm not throwing out my bed to sleep grounded just yet, but thanks +Olivier Malinur
for the heads up. I'll wait for more trials.
Did you know electrons are great at detoxifying ?
I once stuck my finger into 240 volt (long story). I have no toxins left. An iridologist told me.
