Abstract
Abstract The invention relates to an article of skiing footwear wherein in order to damp or absorb impacts on the bone structure of the skier, there is provided in association with the sole a layer which, as distinct from known sole elements made from cellular plastics, is capable of further compression even under maximum shock loading, and the resilience of which in the zone of such maximum shock loading is greater than that of the remaining boot or shoe base under similar loading.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
126 words
An article of skiing footwear, comprising: an inner sole and an outer sole, said inner sole being superimposed on said outer sole; shock-absorbing material having the characteristics of resilient compressibility which remains constant or decreases during an increasing load thereon and resists lateral expansion during said increasing load thereon; means defining an area on said footwear adjacent one surface of said inner sole for said shock-absorbing material, said shockabsorbing material substantially filling said area whereby shocks received by said footwear in a vertical direction transverse to the plane of said inner sole may be absorbed by the compressible resilience of said shock-absorbing material without a lateral expansion of said shock-absorbing material, said lateral expansion characteristic of said shock-absorbing material being independent of said area provided therefor.
Claim 2
Dependent Claim
126 words
An article of skiing footwear, comprising: an inner sole and an outer sole, said inner sole being superimposed on said outer sole; shock-absorbing material having the characteristics of resilient compressibility which remains constant or decreases during an increasing load thereon and resists lateral expansion during said increasing load thereon; means defining an area on said footwear adjacent one surface of said inner sole for said shock-absorbing material, said shockabsorbing material substantially filling said area whereby shocks received by said footwear in a vertical direction transverse to the plane of said inner sole may be absorbed by the compressible resilience of said shock-absorbing material without a lateral expansion of said shock-absorbing material, said lateral expansion characteristic of said shock-absorbing material being independent of said area provided therefor.
Claim 3
Dependent Claim
37 words
An article of skiing footwear according to claim 1, wherein said area and said shock- absorbing material filling same is disposed adjacent the inner ball of the foot of the wearer of said article in use thereof.
Claim 4
Dependent Claim
35 words
An article of skiing footwear according to claim 1, wherein said area and said shock absorbing material filling same is disposed adjacent the outer heel region of a wearer of said article in use thereof.
Claim 5
Dependent Claim
18 words
An article of skiing footwear according to claim 1 wherein said shock-absorbing material comprises a cellular plastics material.
Claim 6
Dependent Claim
15 words
An article of skiing footwear according to claim 4, wherein said plastics material comprises polyurethane.
Claim 7
Dependent Claim
24 words
An article of skiing footwear according to claim 1 wherein said shock-absorbing material is disposed below said inner sole in use of said article.
Claim 8
Dependent Claim
26 words
An article of skiing footWear according to claim 1 further comprising means defining recesses in said inner sole, said shock-absorbing material being disposed in said recesses.
