John Wilson Gibbs claimed that his patented "electric shoe" would cure rheumatism.
Kansas City Star - July 23, 1907
How the shoes generated electricity is explained in his 1903 patent (No. 740,548). They contained zinc and copper nails. The two metals, when combined with sweaty feet, would form a galvanic cell, producing a mild electric current.
This invention relates to an electric shoe; and its object is to provide, in connection with the sole of a shoe or other article of footwear, a means permanently attached thereto, such that an electric current will be generated under the influence of the foot of the wearer. . .
The sole of the shoe is shown at A, and in the upper surface thereof there are driven or otherwise inset a series of nails or studs B, with each of which there is associated a similar nail or stud C. The studs of the series B are preferably of zinc and those of the series C preferably of copper, thereby providing pairs of elements of dissimilar metals or opposite in sign such that when contacted with by the foot of the wearer from the influence of the warmth or moisture of the person or for other reasons an electric current will be generated, passing from one element to the other through the body of the wearer. The medical and therapeutic effects of such a current are well known, and I claim herein only the specific construction of the means for obtaining such a current.
What he doesn't mention is that the metals would quickly corrode, at which point the electricity would stop. Not that such a tiny amount of electricity would have had any therapeutic effect anyway.
Of course, this was back in the era when adding the word "electric" to any product was a sure way to give it more consumer appeal. A long time ago I had a brief article published in Smithsonian magazine in which I gave some examples of this phenomenon.
These were mini slippers that supposedly helped one lose weight. How? Something to do with reflexology and magnets. And also, I assume, the extra effort required to balance in them.
I obeyed all the instructions. I started off gradually. In fact I had to — my arches, bearing almost all of my weight, hurt fiercely the first few days. (If you've ever climbed a round-runged ladder in your bare feet, you know the feeling.) I never went over the 2-1/2-hour limit, and I tried to "respect the slippers" in spite of jeers from my office mates. In a sense, I even "became One with the slippers"—they delivered a terrible foot odor each time I took them off. Apparently, the canvas uppers don't "breathe."
A high heel for women is provided. The high heels according to the current invention have at least two tall heels fixed to rear end of the bottom of sole of the shoes... The multi heeled high heels according to current invention reduces dislocation of wearer's ankle though the heels are narrow and long.
But why stop at two heels when you could have seven?
