Abstract
Abstract A midsole assembly for an athletic shoe comprising a midsole and a corrugated sheet. The midsole is formed of soft elastic material. The corrugated sheet is disposed in at least a heel portion of the midsole. Either or both amplitude and wavelength of wave configuration of said corrugated sheet are made different either or both between a front end portion and back end portion, and between an medial portion and lateral portion of said heel portion.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
117 words
A midsole assembly for an athletic shoe comprising: a midsole formed of soft elastic material; and a corrugated sheet made of plastic material, said sheet being disposed in a heel region of said midsole, said corrugated sheet extending across the full width of said heel region, said heel region having a substantially constant thickness, amplitude of wave configuration of said corrugated sheet being made different between a medial and a lateral portion of said heel region, said corrugated sheet thereby providing a higher compression hardness or lower cushioning properties in said lateral portion of greater amplitude than said medial portion of smaller amplitude of said heel portion; and, wherein said corrugated sheet is comprised of fiber-reinforced plastic.
Claim 2
Dependent Claim
117 words
A midsole assembly for an athletic shoe comprising: a midsole formed of soft elastic material; and a corrugated sheet made of plastic material, said sheet being disposed in a heel region of said midsole, said corrugated sheet extending across the full width of said heel region, said heel region having a substantially constant thickness, amplitude of wave configuration of said corrugated sheet being made different between a medial and a lateral portion of said heel region, said corrugated sheet thereby providing a higher compression hardness or lower cushioning properties in said lateral portion of greater amplitude than said medial portion of smaller amplitude of said heel portion; and, wherein said corrugated sheet is comprised of fiber-reinforced plastic.
Claim 3
Dependent Claim
18 words
The midsole assembly of claim 1 , wherein fibers of said fiber-reinforced plastic are aligned in one direction.
Claim 4
Dependent Claim
28 words
The midsole assembly of claim 2 , wherein fibers of said fiber-reinforced plastic are oriented to the direction coinciding with the direction of ridges of said wave configuration.
Claim 5
Dependent Claim
28 words
The midsole assembly of claim 2 , wherein fibers of said fiber-reinforced plastic are oriented within ±30° with relation to the direction of ridges of said wave configuration.
Claim 6
Dependent Claim
36 words
The midsole assembly of claim 1 , wherein fibers of said fiber-reinforced plastic are woven by filling and warp, the modules of elasticity of said filling being larger than or equal to that of said warp.
Claim 7
Dependent Claim
25 words
The midsole assembly of claim 5 , wherein said filling is oriented to the direction coinciding with the direction of ridges of said wave configuration.
Claim 8
Dependent Claim
25 words
The midsole assembly of claim 5 , wherein said filing is oriented within ±30° with relation to the direction of ridges of said wave configuration.
