Abstract
Abstract A system for securing a foot or inner shoe (4) in the toe or instep region of a shell (3), in particular a ski-boot (1) with a hinged rear part (2), comprises plate-shaped parts (6) which overlap the instep or inner shoe (4) and can be adjusted in relation to the shell (3). Two plate-shaped parts (6) are connected in an articulated manner to the outside of the sole on both sides of the longitudinal central plane of the boot (1) and overlap one another in the instep region. Preferably, the plate-shaped parts (6) are overlapped at least partially by tension elements (11), in particular clampable cables or strips, whereby preferably a clamping element (17) of a clamping device engages with the tension elements (11).

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
136 words
A system for securely and comfortably holding a foot in a boot, particularly in the toe and instep regions, comprising: a shell covering at least the toe and instep regions; a sole; an inner shoe adapted to fit within said shell; first and second plate-shaped parts, each connected to an opposite side of said sole along the longitudinal axis of said sole, extending over said inner shoe so as to overlap each other in the toe and instep regions without being attached to each other wherein said plate-shaped parts may move freely with respect to each other in the overlapping regions; and tension element means for adjusting the position of said plate-shaped parts with respect to said shell and to said instep and toe regions of the foot and for distributing pressure on said plate-shaped parts.
Claim 2
Independent Claim
136 words
A system for securely and comfortably holding a foot in a boot, particularly in the toe and instep regions, comprising: a shell covering at least the toe and instep regions; a sole; an inner shoe adapted to fit within said shell; first and second plate-shaped parts, each connected to an opposite side of said sole along the longitudinal axis of said sole, extending over said inner shoe so as to overlap each other in the toe and instep regions without being attached to each other wherein said plate-shaped parts may move freely with respect to each other in the overlapping regions; and tension element means for adjusting the position of said plate-shaped parts with respect to said shell and to said instep and toe regions of the foot and for distributing pressure on said plate-shaped parts.
Claim 3
Dependent Claim
32 words

Claim 4
Dependent Claim
42 words
The system of claim 2, wherein said first and second plate-shaped parts are each connected to said sole by web means for reducing confinement of lateral areas of the foot and for minimizing the occurrence of pressure points in such lateral areas.
Claim 5
Dependent Claim
42 words
The system of claim 1, wherein said first and second plate-shaped parts are each connected to said sole by web means for reducing confinement of lateral areas of the foot and for minimizing the occurrence of pressure points in such lateral areas.
Claim 6
Dependent Claim
38 words
The system of claim 1, further comprising adjusting element means located on the exterior of the boot for adjusting said tension element means, wherein at least one said plate-shaped part is cooperatively joined with said adjusting element means.
Claim 7
Dependent Claim
38 words
The system of claim 3, further comprising adjusting element means located on the exterior of the boot for adjusting said tension element means, wherein at least one said plate-shaped part is cooperatively joined with said adjusting element means.
Claim 8
Dependent Claim
18 words
The system of claim 6, wherein said tension element means reach at least partially over said plate-shaped parts.
Claim 9
Dependent Claim
35 words
The system of claim 1, wherein said tension element means traverse itself, further comprising at least one crossing point at which said tension element means may be displaced along the longitudinal axis of the boot.
Claim 10
Dependent Claim
35 words
The system of claim 7, wherein said tension element means traverse itself, further comprising at least one crossing point at which said tension element means may be displaced along the longitudinal axis of the boot.
Claim 11
Dependent Claim
17 words
The system of claim 1, wherein said tension element means is cooperatively joined with said plate-shaped parts.
Claim 12
Dependent Claim
17 words
The system of claim 7, wherein said tension element means is cooperatively joined with said plate-shaped parts.
Claim 13
Dependent Claim
21 words
The system of claim 9 further comprising vertically adjustable pressure element means for varying vertical pressure exerted on said plate-shaped parts.
Claim 14
Dependent Claim
35 words
The system of claim 1 wherein each of said first and second plate-shaped parts have walls which decrease in thickness from the end thereof which is connected to said sole to the opposing end thereof.
Claim 15
Dependent Claim
35 words
The system of claim 12 wherein each of said first and second plate-shaped parts have walls which decrease in thickness from the end thereof which is connected to said sole to the opposing end thereof.
Claim 16
Independent Claim
124 words
A system for securely and comfortably holding a foot in a shoe, particularly in the toe and instep regions, comprising: a shell covering at least the toe and instep regions; a sole; first and second plate-shaped parts, each connected to an opposite side of said sole along the longitudinal axis of said sole, wherein said plate-shaped parts overlap each other in the toe and instep regions without being attached to each other and wherein said plate-shaped parts may move freely with respect to each other in the overlapping regions; and tension element means for adjusting the position of said plate-shaped parts with respect to said shell and to said instep and toe regions of the foot and for distributing pressure on said plate-shaped parts.
