Abstract
Abstract A midsole for athletic shoes that stores energy. The "honey comb" midsole absorbs the body weight of the athletic and converts the force into a spring-back energy that reduces the workload of leg muscles therefore a reduction of leg muscle fatigue results.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
151 words
A midsole for use in a sole for foot wear comprising a plurality of resilient, air-filled, vertically stacked cells; said cells being six-sided when viewed in vertical cross-section; wherein said six-sided cells are so structured; as to form two acute angles contraposed toward the center of the six-sided cell on its horizontal plane and four obtuse angles contraposed toward the center of the six-sided cell on its vertical plane; wherein said cells are arranged in adjacent vertical stacks; wherein said adjacent vertical stacks of six-sided cells are interconnected by horizontally parallel framework of the midsole's structure; and said interconnecting horizontally parallel framework form a series of resilient six-sided open cells between each adjacent vertical stack; thus forming a resilient honeymomb framework that spans the width and length of the midsole; whereby said honeycomb framework has the characteristic of applying energy to the base of the foot upon release after load compression.
Claim 2
Dependent Claim
151 words
A midsole for use in a sole for foot wear comprising a plurality of resilient, air-filled, vertically stacked cells; said cells being six-sided when viewed in vertical cross-section; wherein said six-sided cells are so structured; as to form two acute angles contraposed toward the center of the six-sided cell on its horizontal plane and four obtuse angles contraposed toward the center of the six-sided cell on its vertical plane; wherein said cells are arranged in adjacent vertical stacks; wherein said adjacent vertical stacks of six-sided cells are interconnected by horizontally parallel framework of the midsole's structure; and said interconnecting horizontally parallel framework form a series of resilient six-sided open cells between each adjacent vertical stack; thus forming a resilient honeymomb framework that spans the width and length of the midsole; whereby said honeycomb framework has the characteristic of applying energy to the base of the foot upon release after load compression.
Claim 3
Dependent Claim
33 words
A midsole in accordance with claim 1 wherein said plurality of resilient cells are vertically stacked in series; and said plurality of vertical stacks span the width and length of the said midsole.
Claim 4
Dependent Claim
149 words
An insole for use inside of a shoe comprising a plurality of resilient, air-filled, vertically stacked cells; said cells being six-sided when viewed in vertical cross-section; wherein said six-sided cells are so structured; as to form two acute angles contraposed toward the center of the six-sided cell on its horizontal plane and four obtuse angles contraposed toward the center of the six-sided cell on its vertical plane; wherein said cells are arranged in adjacent vertical stacks; wherein said adjacent vertical stacks of six-sided cells are interconnected by horizontally parallel framework of the insole's structure; and said interconnecting horizontally parallel framework form a series of resilient six-sided open cells between each adjacent vertical stack; thus forming a resilient honeycomb framework that spans the width and length of the insole; whereby said honeycomb framework has the characteristic of applying energy to the base of the foot upon release after load compression.
Claim 5
Dependent Claim
149 words
An insole for use inside of a shoe comprising a plurality of resilient, air-filled, vertically stacked cells; said cells being six-sided when viewed in vertical cross-section; wherein said six-sided cells are so structured; as to form two acute angles contraposed toward the center of the six-sided cell on its horizontal plane and four obtuse angles contraposed toward the center of the six-sided cell on its vertical plane; wherein said cells are arranged in adjacent vertical stacks; wherein said adjacent vertical stacks of six-sided cells are interconnected by horizontally parallel framework of the insole's structure; and said interconnecting horizontally parallel framework form a series of resilient six-sided open cells between each adjacent vertical stack; thus forming a resilient honeycomb framework that spans the width and length of the insole; whereby said honeycomb framework has the characteristic of applying energy to the base of the foot upon release after load compression.
Claim 6
Dependent Claim
33 words
An insole in accordance with claim 3 wherein said plurality of resilient cells are vertically stacked in series; and said plurality of vertical stacks span the width and length of the said insole.
