Abstract
Abstract A flexible heel shock absorber (11) for insertion within a shoe which absorber (11) has a base with upper (15) and lower (17) faces, said base having a predetermined thickness extending forward along a major portion of the longitudinal axis with the upper face (15) tapering downwardly (at 35) at the forward end (25) thereof. A wall (21) extends above the periphery of the upper face (15) substantially conforming to the shape of the heel of the user. A plurality of open channels (27), separated by partitions (30), extend laterally across the longitudinal axis of the base. Gripping means (33) may be provided on the lower face (17) of the base.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
175 words
A heel shock absorber (11) for insertion within a shoe comprising a base (13) having upper (15) and lower (17) faces and substantially geometrically conforming to the heel end of said shoe, characterised in that said base (13) has a predetermined thickness extending along a major portion of the longitudinal axis thereof with said upper face (15) tapering downwardly at the forward end (25) thereof, in that a wall (21) extends above said upper face (15) at the outer periphery thereof, said wall (21) having a predetermined thickness adjacent said upper face (15) and diminishing in thickness as the height of said wall (21) increases, said wall having an upper edge (23) at a predetermined height above the rear end of said base (13) and side edges (24) tapering downwardly towards said forward end (25); and in that a plurality of substantially open parallel channels (27) are provided in said base, each said channel (27) extending laterally across the width of said base (13) and being separated from adjacent channels (27) by a partition (30).
Claim 2
Dependent Claim
175 words
A heel shock absorber (11) for insertion within a shoe comprising a base (13) having upper (15) and lower (17) faces and substantially geometrically conforming to the heel end of said shoe, characterised in that said base (13) has a predetermined thickness extending along a major portion of the longitudinal axis thereof with said upper face (15) tapering downwardly at the forward end (25) thereof, in that a wall (21) extends above said upper face (15) at the outer periphery thereof, said wall (21) having a predetermined thickness adjacent said upper face (15) and diminishing in thickness as the height of said wall (21) increases, said wall having an upper edge (23) at a predetermined height above the rear end of said base (13) and side edges (24) tapering downwardly towards said forward end (25); and in that a plurality of substantially open parallel channels (27) are provided in said base, each said channel (27) extending laterally across the width of said base (13) and being separated from adjacent channels (27) by a partition (30).
Claim 3
Dependent Claim
27 words
A heel shock absorber as claimed in claim 1, characterised in that said base (13) and wall (21) are integrally formed from a mass of flexible material.
Claim 4
Dependent Claim
31 words
A shock absorber as claimed in claim 1 or claim 2, characterised in that the material from which the absorber (11) is made has a specific gravity between 0.8 and 1.2.
Claim 5
Dependent Claim
29 words
A shock absorber as claimed in any preceding claim, characterised in that the material from which the absorber (11) is made has a durometric hardness between 36 and 50.
Claim 6
Dependent Claim
36 words
A shock absorber as claimed in any preceding claim, characterised in that the wall (21) thereof has an arcuate inner face (31) so as to substantially conform to the shape of the heel of the user.
Claim 7
Dependent Claim

A shock absorber as claimed in any preceding claim, characterised in that a heel recess (19) is provided in a rear portion of said upper face (15).
Claim 8
Dependent Claim
24 words
A shock absorber as claimed in any preceding claim, characterised in that the major longitudinal length of said base (13) includes said channels (27).
Claim 9
Dependent Claim
39 words
A shock absorber as claimed in any preceding claim, characterised in that gripping means (33) depend from said lower face (17) of said base (13) to'facilitate holding of the absorber r11) stationary in a heel region of a shoe.
Claim 10
Dependent Claim
21 words
A shock absorber as claimed in claim 8, characterised in that said gripping means (33) is integral with said base (13).
Claim 11
Dependent Claim
26 words
A shock absorber as claimed in claim 9, characterised in that said gripping means comprises a plurality of pegs (33) subtending from said lower face (17).
Claim 12
Dependent Claim
