A system is disclosed for an insole for use in an article of footwear. The
insole includes a bottom cushion layer; a lower intermediate layer; a
middle flexible layer; an upper intermediate layer; and an upper cushion
layer. The layers are coupled together by either lamination or gluing.
The lower intermediate layer and the upper intermediate layer are
respectively embedded with a first array of magnet elements and a second
array of magnet elements, such that the first array of magnet elements
and the second array of magnet elements generate a repelling magnetic
field that results in a repelling mechanical force that pulls the upper
intermediate layer away from the lower intermediate layer. This invention
is not affected by material fatigue due to prolonged pressure or
temperature stress that is common in insoles for use in articles of
footwear.
