Claim:
1. A bio foot pad for insertion into a shoe, comprising: a plurality of circumferential elastic fibers uniformly located in an arcuate orientation throughout a viscoelastic material such that each fiber includes first and second fiber termination ends, wherein all of the first fiber termination ends are connected together and all of the second fiber termination ends are connected together at separate locations outside of the viscoelastic material for fixation to a shoe counter; wherein the circumferential elastic fibers react to biphasic properties of the viscoelastic material such that the biphasic properties include a solid phase and a fluid phase; and wherein the circumferential elastic fibers, under a compression of the viscoelastic material due to a heel area of a user interacting with the viscoelastic material which generates the fluid phase, develop a plurality of hoop stresses which allow axial forces exerted against the heel area of the user to be evenly distributed along the heel area of the user.
