Total Claims: 12
Claim 1
Independent Claim
104 words
A method for therapeutic treatment of a foot by employing a footwear insole comprising an electric energy producing element, said method comprising placing said footwear insole in an article of footwear and providing a first electric polarity directed to the sole of said foot and a second opposing electric polarity directed to the inner sole of said article of footwear, and by the conductivity of body moisture contained within said article of footwear forming an electric circuit to flow electric energy to said sole of said foot and through said conductive body moisture contained in said footwear to an upper part of said foot.
Claim 2
Independent Claim
104 words
A method for therapeutic treatment of a foot by employing a footwear insole comprising an electric energy producing element, said method comprising placing said footwear insole in an article of footwear and providing a first electric polarity directed to the sole of said foot and a second opposing electric polarity directed to the inner sole of said article of footwear, and by the conductivity of body moisture contained within said article of footwear forming an electric circuit to flow electric energy to said sole of said foot and through said conductive body moisture contained in said footwear to an upper part of said foot.
Claim 3
Dependent Claim
99 words
