Anyone ever heard of these before…I have been experiencing some knee problems from being on my feet all day long and wondered if anyone had ever used them.

Heard about them in an athletics forum.

Sounds iffy to me. the patents part said something about space-age materials enhancing your body’s electromagneic system.
I don’t believe we have an electromagnetic system.
Also, who says “Space Age” anymore? What is this 1965?
