Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
177 words
A sole for use with sport shoes comprising a rigid abrasion-resistant ground sole, the ground sole having a heel portion, an arch portion, and a toe portion, a resilient and elastic interlayer body bonded to said ground sole, and a resilient and elastic interlayer sole bonded to said interlayer body, said interlayer body being extended over and bonded to the heel portion and the shoe arch portion of the ground sole and having uniform thickness at the heel portion and decreasing into a wedge shape toward the top of the shoe arch portion, the interlayer bodying being provided with a plurality of parallel, transversely extending apertures between the upper and lower the surfaces of said interlayer body from its each side to its center, the cross section of each aperture being hexagonal so as to have preferred absorbing power of impact load, the resilience of the interlayer body and the interlayer sole and the air in the apertures permitting preferred absorption of impact load exerted against the heel portion of the sole at the time of landing.
Claim 2
Dependent Claim
177 words

Claim 3
Dependent Claim
21 words
The sole as claimed in claim 1, wherein each aperture penetrates from one side to opposite side of the interlayer body.
Claim 4
Dependent Claim
19 words
The sole as claimed in claim 1, wherein each aperture is disconnected at the center of the interlayer body.
Claim 5
Dependent Claim
21 words
The sole as claimed in claim 2, wherein each aperture communicates to each other at the center of the interlayer body.
Claim 6
Dependent Claim
131 words
A sole for use with sport shoes comprising a rigid abrasion-resistant ground sole, the ground sole having a heel portion, an arch portion, and a toe portion, a resilient and elastic interlayer body bonded to said ground sole, and a resilient and elastic interlayer sole bonded to said interlayer body, said interlayer body being extended over and bonded to the heel portion and the shoe arch portion of the ground shoe and having uniform thickness at the heel portion and decreasing into a wedge shape toward the top of the shoe arch portion, the interlayer body being provided with a plurality of parallel, transversely extending apertures between the upper and lower surfaces of said interlayer body from its each side to its center, the cross section of each apertures being hexagonal.
Claim 7
Dependent Claim
131 words
