Problems solved by technology

Nevertheless both these solutions have their disadvantages when to the most substantial belongs the fact that if the user has a foot which is unsuitably shaped, e.g. the flat-foot, or he treads fully on one's foot in an unsuitable manner etc., the insole shapes itself so that at a further wearing it impairs this defect instead to eliminate it, or at least not to support this defect, and so to improve the quality of user's tread.
The disadvantage of such solutions is that these insoles are shaped in accordance with a unified form of human foot, hence disregarding an individual shaping, which features especially in a diversity of forms and inclination of toes so that in this case the toes of a foot adjust to the structure of the insole while it should happen, in fact, vice versa.
Usage of such insoles is therefore not suitable, moreover not comfortable.
The structure of insoles of both described types results in that during their usage—during walking, but also during sporting all the muscles of lower limbs are not engaged ideally, neither the weight of a human body is not distributed ideally between the big toe joint, little toe joint and the heel bone.
Due to this even at a healthy man with normally shaped foot this leads to an excessive loading of some muscles or ligaments of a foot sole, thus to atrophy and shortening of other not used muscles, to an excessive loading of the big toe joint, and in some cases also to an injury of vascular system in a transversal and longitudinal instep of the bottom sole of a foot, the result of which is not only an abnormal tiredness, but also further physical, possibly even psychic problems, that become worse with the age.
Hence, during sitting the insole according to the CZ patent 298894 behaves in the same or similar manner as the other to date known insoles and the effects which are acting during walking are not effective in this case.
The offset of ankle at children causes walking disability when the child is confined to a wheelchair.

embodiment

OF EMBODIMENT

[0026]Execution of the insole will be described on example of embodiment of the independent inserting insole, nevertheless the principle of the invention may fully be applicable also at reconstruction of stretching insoles, possibly also other shoemaker's products.

[0027]The insole 1 in its ground plan represented in the FIG. 1 by its shape and size is similar to the shape and size of a human foot sole, it comprises the toe section 10, which in the represented variant is planar and smooth both from the upper as well as bottom side. The toe section of the insole continues to form the middle section 100, which further continues to form the heel section 1000 of the insole 1. The toe section 10 of the insole 1 provides support for toes of the foot sole. The middle section 100 of the insole 1 provides a flexible support both for transversal as well as longitudinal instep of the foot sole, for joints of individual toes and for other parts of the foot sole, and the heel section...

Abstract

The insole (1) from the upper side provided with shaping corresponding to the form of impression of bottom part of a human foot sole with recess (5) for the big toe joint with smooth toe section (10), and from the bottom side with shaping corresponding to the bottom part of a human foot sole with smooth toe section (10), while it in a flexible manner supports all parts of the foot sole between the toe section (10) and the heel section (1000). In the heel section (1000) there is performed recess (1201) or depression (120), in which the heel recession (12) is performed.

Description

TECHNICAL FIELD[0001]The invention relates to an inserting insole from the upper side provided with shaping corresponding to the form of impression of bottom part of a human foot sole with smooth toe section, and from the bottom side with shaping corresponding to bottom part of a human foot sole with smooth toe section.[0002]The invention also relates to a stretching insole from the upper side provided with shaping corresponding to the form of impression of bottom part of a human foot sole with smooth toe section.BACKGROUND ART[0003]At present, several different types of inserting or stretching insoles are used, which should in a most comfortable and suitable manner act upon the human foot, to render it the most ideal support, and in some cases also to stimulate some of the ceptors being in the foot sole.[0004]The solution according to DE 3406504 belongs to representatives of this group, where the insole besides others comprises a layer formed by a cork pulp with a soft binding, whi...
