Footwear with heel based arcuate panel-shaped impact absorbing resilient concealed tongue

Abstract

Footwear includes an arcuate, resilient, panel-shaped tongue concealed in the heel to absorb impact forces and facilitate the natural rolling contact of an individuals foot when the individual is walking or running.

1 . Footwear comprising
 (a) a sole including an upper portion and a lower portion, said upper and lower portions bounding a space extending therebetween and having at least two operative positions,
 (i) a first operative position with said upper portion spaced a first selected distance apart from said lower portion; and, 
 (ii) a second operative position with at least one of said upper and lower portions displaced toward the other when a compressive force is applied to said sole such that said upper and lower portions are spaced a second selected distance apart less than said first selected distance; 
   (b) an outer covering attached to and extending upwardly from said upper portion of said sole and shaped and dimensioned to extend over at least a portion of a human foot; and,   (c) a elastic panel-shaped tongue extending intermediate said upper and lower portions and resiliently deflectable when said compressive force is applied to said sole to roll over said lower portion and generate a force opposing said compressive force.
