Abstract
A shock absorbent shoe sole (10) including an upper sole (14) and a bottom sole (12) attached to the bottom of the upper sole, the bottom sole including one or more inverted cups (22, and 24) disposed therein; each cup is located directly beneath and pointed convexly toward a natural contact point (60, 62, 64) of the human foot (54) for absorbing and dispersing shock generated at the natural contact point during a foot step.
Claims12
A shock absorbent shoe sole comprising:
- (a) an upper sole having a thickness;
- and
- (b) a bottom sole attached to the bottom of said upper sole and including one or more inverted cups dispersed therein, each cup being located directly beneath and pointed convexly toward a natural contact of the human foot for absorbing and dispersing shock generated at said natural contact point during a foot step, each of said cups including a cup shaped cavity penetrating the thickness of the upper sole to such a degree that the upper sole plays essentially no part in absorbing shock at the natural contact point during a footstep.
a shock absorbent shoe sole comprising:
- (a) an upper sole;
- and
- (b) a bottom sole attached to the bottom of said upper sole and including one or more inverted cups dispersed therein, each cup being located directly beneath and pointed convexly toward a natural contact of the human foot for absorbing and dispersing shock generated at said natural contact point during a foot step, said bottom sole including one or more relatively thick portions, each having an inverted cup dispersed therein and said upper sole including one or more recesses therein, each said recess accomodating one said thick portion of said bottom sole such that a relatively thin portion of said upper sole is interposed between each said inverted cup and a natural contact point of the foot.
A shock absorbent shoe sole comprising:
- (a) an upper sole;
- and
- (b) a bottom sole attached to the bottom of said upper sole and including one or more inverted cups dispersed therein, each cup being located directly beneath and pointed convexly toward a natural contact of the human foot for absorbing and dispersing shock generated at said natural contact point during a foot step, said bottom sole including one or more relatively thick portions, each having an inverted cup dispersed therein, and said upper sole including one or more openings therethrough, each said opening accomodating one said thick portion of said bottom sole such that said thick portion of said bottom sole such that said thick portion is substantially flush with the top surface of said upper sole.
