Abstract

Abstract A shoe sole construction designed so as to be biodynamically shock-absorbing.In the sole (2) are provided two cushions (8, 9) which are filled with a fluid (10) and interconnected by means of a number of channels (11). One cushion (8) is positioned underneath the heel (6) of the foot and the other cushion (9) is positioned underneath the transverse forward arch (7) of the foot.When the wearer of the shoe sets down his foot into contact with the ground, the heel strikes the ground first and a shock-absorbing effect is then obtained as the rear cushion is compressed. Upon this compression, fluid flows from the rear cushion (8) to the front cushion (9), which expands and lifts the front arch of the foot, releaving the weight thereon and supporting the front arch when the forefoot is set down on the ground. When the wearer continues the walking cycle, the forward cushion (9) is compressed, causing the rear cushion (8) to expand and the latter is again ready to provide a shock-absorbing effect upon the next step and heel strike.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 114 words
A shoe sole construction, characterised in that the sole (2) comprises at least two cushions (8, 9) which are partly or completely filled with a fluid (10), said cushions (8, 9) adapted to cooperate and positioned in said sole (2) essentially beneath the heel region (6) and beneath the region of the front transverse arch (7) of the foot, said cushions (8, 9) arranged to cooperate so as to ensure that compression of the rear cushion (8) causes expansion of the front cushion (9) and vice versa, and that upon expansion of the front cushion (9) the shoe sole is caused to form a supporting bulge beneath the front arch (7) of the foot.
Claim 2
Dependent Claim 114 words
A shoe sole construction, characterised in that the sole (2) comprises at least two cushions (8, 9) which are partly or completely filled with a fluid (10), said cushions (8, 9) adapted to cooperate and positioned in said sole (2) essentially beneath the heel region (6) and beneath the region of the front transverse arch (7) of the foot, said cushions (8, 9) arranged to cooperate so as to ensure that compression of the rear cushion (8) causes expansion of the front cushion (9) and vice versa, and that upon expansion of the front cushion (9) the shoe sole is caused to form a supporting bulge beneath the front arch (7) of the foot.
Claim 3
Dependent Claim 51 words
A shoe sole construction as claimed in claim 1,[ characterised in that two cushions (8, 9) are provided and in that one (9) of said cushions is positioned underneath the front transverse arch (7) of the foot whereas the other cushion (8) is positioned underneath the heel (6) of the foot.
Claim 4
Dependent Claim 26 words
A shoe sole construction as claimed in claim 1 or 2, characterised in that said cushions (8, 9) are interconnected by one or several channels (11).
Claim 5
Dependent Claim 32 words
A shoe sole construction as claimed in claim 3, characterised in that the total cross-sectional area of said channel or channels (11) is less the cross-sectional area of the cushions (8, 9).
