BRIEF SUMMARY
FIELD OF INVENTION
This invention relates to a shoe sole or outsole according to the preamble to claim 1.
The invention also relates to a shoe, according to the preamble of claim 12, having such a sole.
SCOPE OF THE PRIOR ART
The design of shoe soles or outsoles was and is a problem with which man long has been and still is concerned. In the area of modern shoe manufacture a trend has developed in which prefabricated soles are used which, after manufacture, are suitable for combining with the other elements of a shoe (insole, upper, etc.) without any additional processing steps being necessary.
DE GM 90 14 122.9 discloses a prefabricated sole for shoes comprising a sole surface wherein projecting elements in the form of webs are disposed on the inside of the sole facing the insole and extend transversely of the longitudinal direction (longitudinal axis of the sole). In the heel zone and partly in the intermediate zone between the heel zone and the ball of the foot zone, a longitudinal web extending in the direction of the longitudinal axis is provided in the area of the longitudinal centre-line of the sole in those zones. The transverse webs extend from the tip of the sole to the end zone of the heel zone in parallel relationship and are defined by an edge at the respective ends.
DE OS 25 30 403 discloses a sole for high-heeled shoes wherein elements in the form of a rectangular grid are provided which project inwards from the sole surface to the insole, the web-like edges of the grid extending diagonally, i.e. including an angle of about 45.degree. to the sole longitudinal axis.
EP 185 781 discloses a shoe sole of plastics or rubber wherein a diamond-shaped grid is provided in the heel zone and in the ball of the foot zone, the grid webs extending obliquely to the longitudinal axis of the shoe and being inclined forwardly in order to allow the foot to be resiliently supported and damped during walking.
It has long been known medically that the most natural and healthiest form of walking is barefoot walking. What is involved here is that during walking naturally the foot rolls on the sole from the heel as far as the toes and a specific pressure distribution is obtained at the sole surface of the foot and comprises substantially a linear pressure peak line extending in the longitudinal direction.
However, all soles of the above-cited prior art specifications have the disadvantage that because of the design of the inwardly projecting elements, on the one hand, and the design of the underside of the sole surface, on the other hand, walking complying with the optimal medical requirements is not rendered possible.
SUMMARY OF THE INVENTION
The object of this invention, therefore, is so to improve a shoe sole or outsole of resilient material of the type referred to in the preamble that it is possible for walking in the shoe to correspond substantially to barefoot walking.
The invention also relates to a shoe having such a sole.
To this end, according to the invention, the elements projecting at the underside are interrupted webs which extend substantially transversely of the sole longitudinal direction or longitudinal axis, at least one longitudinal rib is provided parallel to the sole outer contour on the sole underside at least along the outside of the sole and has a distance from the sole outer contour distinctly less than half the sole width in the heel zone, and a sickle-shaped reinforcement zone filling the grid is provided between the ball of the foot zone and the heel zone and extends from the sole inside in the direction of the longitudinal axis of the sole.
This design gives a sole rolling behaviour substantially corresponding to a natural rolling behaviour of the human foot.
Advantageously, this sole provides a very slip-proof configuration which thus serves for all-weather use including use in snow or on a non-consolidated subsoil.
Advantageous embodiments of the shoe sole or outsole according to the invention will be apparent from the sub-claims.
By constructing the projecting elements integra
