Description

Shoe sole and insole for shoes

The invention relates to a shoe sole with a sole element and an insole with a sole element for shoes.

From DE 11 2004 001 279 T5 a shoe sole with a reinforcing element is known which has a forefoot part, a midfoot part in the area of the arch of the foot and a rearfoot part, wherein the forefoot part and the rearfoot part have a ground contact surface. It is provided that the first and second foot part are connected to each other by a soft arch, as shown for example in Figures 8a to 8d and that the forefoot part and rear foot part are connected by a reinforcing element with another vault. This reinforcing element is designed, for example, as I, X, N or O.

CONFIRMATION COPY By this embodiment of the shoe sole with a reinforcing structure, a shoe sole is to be created, which has a light weight, prevents distortion, has improved adaptation properties and prevents the upward impact. By avoiding twisting, however, the problem arises, as in most conventional shoe soles, which have a hinge movement in the so-called shoe joint between heel and shoe sole that the function of the arch of the foot is obstructed. By restricting the twisting movement, the feet tire quickly. Therefore, it is necessary that physiological soles allow the natural movement of the arch of the foot. For this purpose, it is necessary that the tension of the longitudinal and transverse arch physiologically transforms the kinetic energy when it occurs and strains into stress energy and converts this back into kinetic energy when the foot is pushed off. For this, the arch of the foot must be able to stretch, contract and twist on the inside of the foot. In conventional shoes, this is hardly possible. Because of this, the ligaments of the foot and the short foot muscles degenerate. Thus, over time, the vault of many people gets out of shape and the economy of walking and running deteriorates.

In addition, conventional shoes are often provided with a strong cushioning. This is only logical, because if the feet can no longer absorb the kinetic energy, it must at least be absorbed. This not only destroys the energy that could be used for walking and running, it also creates damaging impulses and strain on the foot and on the large joints of the leg despite all the damping. Hocks and knees diverge inward or outward, and hips rotate in or out, depending on how the body compensates for the lack of function. This in turn leads to discomfort to muscles, tendons and joints, which often extend to the spine.

The natural rolling process of a foot can be divided into four phases: 1. When putting on the heel, the energy of the impact is partially guided over the anklebone head in the longitudinal arch by this is tense.

2. This tension is further increased by the body weight acting on the vault arch. This reduces the longitudinal and transverse vault. There is a flattening of the arch of the foot, which is accompanied by an extension of the foot.

3. The elastic tension reaches its maximum when pushed off the ground,

4. Then the energy of the tension returns to kinetic energy, which gives the body an impulse forward. The movement of the big toes ensures the best possible grip and a final push before lifting the leg. During this phase, the arch of the foot raises again and there is a shortening of the total foot.

When the arch of the foot lifts and shortens or lowers or lengthens, it mainly occurs on the medial (inner) side of the foot while the lateral (outer) side of it remains largely unaffected. This results in an abduction and adduction movement in the metatarsal tarsal joint. For most shoe soles or insoles for soles this unwinding is only partially possible or supported.

The invention is therefore based on the object to provide a shoe sole or an insole, which supports the Abrollgang of the foot in its natural form and thus allows the natural movement of the arch of the foot.

This object is achieved by the shoe sole according to the features of claim 1 and by an insole according to the features of claim 18. Further advantageous embodiments and further developments are specified in the respective claims. The shoe sole according to the invention has a sole element, which has a Vorfußab- cut in the forefoot part of the shoe sole and extending into the rear foot part of the shoe sole rear leg portion which are integrally connected via a web-shaped midfoot portion, wherein at least in the midfoot portion or between the rear foot and at least one arc with an arcuate recess or at least one slot is provided in the midfoot portion, which is designed to be open medially and laterally comprises a web-shaped midfoot portion which articulates the forefoot portion to the rearfoot portion. This makes it possible that the rolling process is supported in its natural form. On the one hand, the abduction and adduction movement is supported. Furthermore, this embodiment can lift the Fußlängsgewölbe and lower and shorten and extend. This also allows the torsion and contraction of the metatarsus and tarsus due to the laterally disposed ridge-shaped midfoot portion. In particular, the torsion takes place about an axis which runs approximately along the fourth and / or fifth beam of the foot. Furthermore, the shoe sole according to the invention comprises at least one elastic tension which extends from the rear foot portion at least to the midfoot portion. By arranging the at least one train in combination with the at least one arch or at least one slot, the articulated connections of the anklebone (talus) to the heel bone (calcaneus) and to the navicular bone (navicular) are supported elastically and dynamically. Thus, both a natural roll-off behavior of the foot and a preload in the direction of twisting, forefoot adduction and -flektion is possible. This shoe sole, which is also called archery, therefore follows the movements in the tarsus. It promotes the twisting movement when walking, running and jumping. It promotes natural cushioning by converting kinetic energy into elasticity, which is available again when pushed off the ground. This results in a total movement a slight upward and downward rotation of the forefoot in the fulcrum on the outside in the area of the bases of the fourth and fifth metatarsals. The so-called spiral dynamics, in which the arch of the foot twists in the tarsus-metatarsal complex, is maintained. The Sole element may be a part of the shoe sole or even be designed as a shoe sole.

Furthermore, at least one arch or at least one slot is preferably provided in the forefoot part, in particular proximally and / or distally, of a big toe ball. This further increases the torsion and contraction of the medial side of the sole element or the shoe sole. As a result, the shoe sole can better follow the contraction of the arch of the foot and support it.

A further preferred embodiment of the invention provides that the at least one arc or at least one slot in the sole element is filled by a soft elastic material. As a result, a quasi-closed surface or a compact sole element is created. In particular, in the embodiment of the sole element as a shoe sole can be done on the one hand a closed sole surface and on the other hand a high elasticity to support the Abrollvorganges the foot in its natural form. If the sole element is provided as an insert part in the shoe sole, the at least one arc or at least one slot can be formed free of an elastic material. The further components surrounding the sole element for forming the shoe sole or the shoe likewise have at least one slot or at least one arc, which are filled with the softer elastic material and thus closed.

It is preferably provided that the one elastic pull or a "first pull" extends medially along the sole element, this first pull extending along the rear foot section, ie in the heel region, at least to the midfoot section or to the forefoot section Contraction stress on the inside of the sole element in the sense of adduction of the forefoot and inversion of the heel are achieved, whereby the articulated connections between anklebone (talus), heel bone (calcaneus) and navicular (Naviculare) together with the pan band (lig. Calcaneanaviculare plantare) dynamically supported This first move is also called Tibialis-Zug, which corresponds approximately to the course and function of the tendon of the tibialis posterior muscle.

Further, an elastic train or a second elastic train is preferably provided on the underside of the sole element, which extends from the outside of the heel, ie from the hindfoot portion or an outer side of the hindfoot portion, to the transition of metatarsus and tarsal root on the inside of the sole element. This further train corresponds in its course and function approximately to the tendon of the M. fibularis longus. This further pull also supports the joints below the anklebone (subtalar joint and articulatio talo-calcaneo-naviculare). In addition to a contraction bias this train creates a torsional bias in the sense of an opposite movement of the forefoot and heel, ie forefoot and hindfoot, that is, a pronation of the forefoot and an inversion of the heel. "Pronation" of the forefoot is understood to mean a downward turn of the foot's inner edge and an "inversion" of the heel means an inward turn of the heel.

Particularly preferably, the two above-described elastic features in combination with at least one arc or at least one slot, which is designed to be open medially and laterally comprises a web-shaped midfoot portion provided. These two features have a supporting and stabilizing effect on the shoe joint or sole joint formed between the forefoot portion and the hindfoot portion and support the elastic and dynamic support. Furthermore, additional elastic traction may be provided for support.

Furthermore, it is preferably provided that a further or third train is provided which corresponds to the course of the tendon of the long toe bend and is referred to as a flexor train. This pull extends from an outside of the heel-supporting hindfoot section to the forefoot section in the groin ball or big toe area. As a result, the sole element or the shoe can better adapt to the forefoot. According to a preferred embodiment of the invention it is provided that the web-shaped midfoot portion of the sole element includes a stiffening element under the fourth and fifth beam of the foot. The fourth and fifth ray of the foot lies on the outside of the foot. For a more detailed explanation, reference is made to FIG.

Furthermore, it is preferably provided that the convexity of the arch to the arcuate recess in the region of the fourth metatarsal bone is located and that a respective end of the arc is directed to the inside of the midfoot portion and the ends are proximal and distal to the apex of the convexity of the arc. This will allow the extension and shortening of the foot created during the flattening and raising of the foot arch to be optimally assisted, so that the foot will transform the kinetic energy upon occurrence and stressing into stress energy, and then turn it into kinetic energy upon repulsion of the foot can implement.

Furthermore, it is preferably provided that the web-shaped midfoot portion is designed to be rigid in the vertical direction and less extensible. This ensures the stability of the shoe sole while at the same time providing maximum support for the rolling movement of the foot in terms of torsion, extension and contraction.

According to a first embodiment of the shoe sole is provided that the sole element has a planar contour, in particular as a flat plate-shaped element is formed. This is a very simple embodiment and allows for easy integration into a shoe sole, wherein the previous structure of the shoe can basically be maintained with the exception that at least in the area of the arch of the foot a very elastic and soft material with respect to sole and upper is provided, which does not hinder the raising and flattening of the arch of the foot and the concomitant extension and shortening of the midfoot. According to a further preferred embodiment of the invention, it is provided that the forefoot portion and the rearfoot portion of the sole element are connected to each other medially by a vault support. This arch support, which is particularly elastic, supports the shoe joint. At the same time, this can assist in the transformation of the energy of tension when the foot is pushed back into kinetic energy.

A further preferred embodiment of the sole element configured with a vault support provides that the vault support is bar-shaped and, compared with the forefoot portion and rear foot portion, comprises an elevated course adapted to the arch of the foot. Thus, the user also achieves the conventional feel of a shoe with a arched support, although the freedom of movement of the extension and the flattening of the arch of the foot continues to be made possible when the foot is put on.

According to a further preferred embodiment of the sole element is provided that in the overlapping region of the arch support and the forefoot portion and the arch support and the hindfoot portion of the forefoot and hindfoot portion are inclined or curved upwards and so form a support of the arch of the foot. As a result, an improved adaptation of the shoe sole to the contour of the arch of the foot can be achieved.

Furthermore, it is preferably provided that the trains are designed as a force storage element. Thereby, the sole element can be provided with a resilient bias, which is particularly adaptable to different foot shapes and weight classes.

A further alternative embodiment of the sole element provides that it has a rear foot section which comprises an O-shaped configuration, which is adjoined tangentially by the midfoot section, which merges into a hook-shaped forefoot section. As seen in plan view, this embodiment also has a δ-shaped contour. This alternative embodiment allows that through the O-shaped Enables improved fixation of the heel to the sole element, the other functions are maintained.

It is preferably provided that the regions of the hindfoot section, the midfoot section and the forefoot section attached to the arch of the δ-shaped sole element are arched upward to support the arch of the foot. In this case, this curvature is formed concurrently with the arch of the foot. As a result, improved support of the arch of the foot can be achieved.

Furthermore, it is preferably provided that the O-shaped rear foot section within the O has a recessed receiving area for the heel in relation to an outwardly extending edge area. As a result, an improved embedding of the heel in the sole element can be achieved. At the same time, the upwardly curved contour can be provided in such a way that immediate tilting or premature buckling of the heel is prevented. Thus, the effect of the sole element as Antipronationsstütze is additionally supported, d. H. preventing premature kinking of the tarsal root and supporting the function of the acetabular band.

Furthermore, it is preferably provided that a force storage element, preferably replaceable, is provided medially between the free hook-shaped end of the forefoot section and the rear foot section. This in turn an internal elastic tension can be achieved, which allows a specific adaptation to foot shapes and weight classes.

Such energy storage elements can be ^{ausgebil ¬} det as elastic plastic tape or plastic strip with a high modulus of elasticity.

The sole element is preferably designed as a reinforcing element which can be inserted into the shoe sole or integrated into it. The sole element may, for example, be reinforced and, while retaining the conventional construction of a shoe sole in this in be integrated by, for example, the sole element in the

Layer structure of the sole is involved. Alternatively, the sole element can also be used in the shoe sole to connect them together. It is preferably provided that the shoe sole, in particular the tread or ground contact surface of the shoe sole, congruent to the sole element comprises at least one arc or at least one slot, so that a deformation of the foot ^¬ vault allows for tension and relaxation and a very good ride is achieved ,

The object underlying the invention is further achieved by an insert for a shoe sole, which has a sole element according to one or more features of the protruding sole element for the shoe sole. The same applies to the sole element which is integrated into an insole in order to insert it into a shoe.

It is preferably provided that the insole comprises at least at the forefoot and / or rear foot section a fixing element for engagement in a shoe sole. As a result, the insert can be arranged in a defined position.

The invention and further advantageous embodiments and developments thereof are described in more detail below with reference to the examples shown in the drawings and explained. The loading ^¬ letters and drawings to be extracted features may be used individually according to the invention on their own or in any combination. Show it :

In the figures la and lb a bone structure of the foot 9 is shown, whose structure is well known. For the description of the following invention is merely shown what is to be understood by the first to fifth beam 11 to 17. The first, second and third beam 10, 11, 12 of the foot relate to the metatarsal bones, which are in each case connected via a sphenoid bone 14 with a navicular bone 15. This first to third beam 10, 11, 12 moves relative to the fourth and fifth beam 16, 17, that is, the first to third beam 10, 11, 12 are involved in the flattening and raising of the arch of the foot and an extension and shortening of the foot 9 immediately after the rolling of the heel. The fourth and fifth beams 16, 17 form the torsion axis when the forefoot is unrolled. Since they are less mobile than the medial rays and give less under load, these direct the force and weight at the end of the unrolling phase on the

Big toe.

FIGS. 2 a and 2 b show schematically a shoe sole 21 of a shoe 20. This shoe sole 21 consists at least of a sole element 22, which according to this embodiment comprises a tread. Alternatively, a running surface can also be applied or glued on the sole element 22 separately or else only partially applied. The shoe sole 21 includes a Vörderfußteil 23, a rear foot 24 and a midfoot part 26. The sole member 22 preferably includes a forefoot portion 28, a rear foot 29 and a midfoot portion 31 which connects the forefoot portion 28 and rear leg 29. In the region of the midfoot portion 31, at least one slot 32, preferably a plurality of slots 32, is provided, which are designed to be open on the medial side. These slits 32 extend to a ridge-shaped midfoot portion 31. These slits 32 preferably completely pass through the shoe sole 31, so that the forefoot portion 28 and the rearfoot portion 29 of the sole element 22 as well as the shoe sole 21 or the ground contact surface are articulated via the midfoot portion 31 and the midfoot portion 26, respectively connected to each other so as not to hinder the torsional movement and contraction of the arch of the foot during the rolling movement.

The slots 32 are preferably filled by a soft elastic material. In all weather shoes, the slot 32 is closed at least with respect to the ground contact surface. In summer shoes, the slit 32 may also be partially permeable to simultaneously act for air circulation and a comfortable foot climate. In the embodiment illustrated in FIG. 2 a, at least one further slot is preferably respectively proximal and distal to the big toe ball

32 provided to allow an even better freedom of movement for the arch of the foot.

The embodiment of the shoe sole 21 according to FIG. 2 a can be modified such that a tension 71 and a tension 74 are provided on the medial outer side of the shoe sole 21 as a force storage element, as shown in FIG. 2 b. These trains 71, 74 may be interchangeably provided to be replaced when fatigued or to adjust the tension so that each wearer also gets a good running feeling depending on his body weight.

As an alternative to the slot (s) 32, at least one bow can also be used

33 may be provided with an arcuate recess which is described in more detail in the following embodiments.

FIGS. 3a and 3b show an alternative embodiment of a shoe sole 21 according to FIGS. 2a and 2b. In this shoe sole 21 is provided that at least in the region of the midfoot portion

31 one or more slots 32 are provided which are formed open on the medial side. In addition, one or more slots can

32 may be provided in the transition region to the rear foot section 29 and also in the rear foot section 29. These slots 32 are preferably triangular in cross-section and may in particular have a concertina shape, that is, that the slots 32 are mutually introduced with respect to the triangular shape. In addition, one or more slots 32 can also be introduced in the forefoot section 28, which are shown in phantom.

At this shoe sole 21, a train 71 is provided, which is arranged medially on the sole element 21 and adjacent to the slots 32 or this is provided at least partially overlapping. This pull 71 is elastic and the course corresponds to the tibial tendon, which creates a contraction bias and supports the joints below the talus. This train 71 has the same function and can individually can be adjustably provided on the outside of the shoe sole 21 or changeable in the shoe to be attached to the sole element 22. Furthermore, the shoe sole 21 comprises a train 72, which is referred to as a fibularis train. By this train 72, a torsional stress is generated in analogy to the fibularus longus tendon. The course of this train 72 also corresponds to the Fibularissehne, that is, this train 72 extends from an outer side of the rear leg 29 diagonally to the medial side of the midfoot portion 31 and ends in a transition region between the midfoot portion 31 and the forefoot 28 or in the forefoot 28.

By such a combination of slots 32, which may also be formed as arches, as described in the following figures 4a and b and the trains 71, 72, which give a bias towards torsion, Vorfußadduktion and flexion, a shoe ^¬ sole 21, which follows the movements in the tarsal root and promotes dynamics in walking, running and jumping.

Such trains 71, 72 may be made of rubber, steel springs or TPU (thermoplastic polyurethanes), for example, as well as a Elastogran or the like can be used.

Another preferred embodiment of the shoe sole 21 provides that in addition to the two trains 71, 72, a further train 73 is provided, which is referred to as flexor train. This flexor pull corresponds to the course of the flexor tendon. This train 73 may also like the train 72 at the same point or adjacent to attack on an outer side of the rear foot 29 of the shoe sole 21 and extend to the forefoot 28 at the shoe sole end or end in the area of the big toe ball or the big toe. As a result, the sole element 22 can better adapt to the forefoot and release the toe diffraction ^¬ better.

By means of an embodiment of the sole element 22 according to FIGS. 3 a and b with the slots 32 and the features 71, 72 and optionally the tension 73, a sole element 22 is thus created, which is twisted of the foot when walking, promoting the medial contraction of the foot as well as the adduction of the forefoot. Such a distortion of the foot culminates in the area of the pan band. For this purpose, the sole element has an elastic zone which tapers according to the shape of the longitudinal arch to the outside of the shoe. With increasing torsion it bulges elastically and acts as a dynamic longitudinal arch support, especially in the area below the talus. The elastic features 71, 72 and possibly 73 give in the front shoe sole 21 a pronatorische bias and a contraction and adduction bias, while the heel part of the shoe sole 21 undergoes an inversion bias. As a result, this sole element 21 gives the impulse of impact when placing the heel on the ground in a manner similar to the natural tension of the foot skeleton. This supports the natural damping, whereby the kinetic energy is transferred in the phase of the impact as tension energy in the tensions of the foot arch, the calf muscles and the short foot muscles.

The arrangement of the trains 71, 72 and possibly 73 can also be integrated in the shoe sole 21 in the embodiments described below.

In Figure 4a, a shoe sole 21 is shown schematically, in which a sole element 22 is arranged. This can be formed as an insert and / or as a reinforcing element. The shoe sole 21 comprises a forefoot part 23, a rearfoot part 24 and a midfoot part 26. The forefoot part 23 and the rearfoot part 24 have a ground contact surface. The middle foot part 26 may likewise have a ground contact surface, but this outer side is preferably set back from the ground contact surface of the forefoot part 23 and the rear foot part 24.

In the shoe sole 21, the sole element 22 is incorporated. The Soh ^¬ lenelement 22 can be over the entire shoe sole 21 erstre ^¬ washer or constructed as this. This sole element 22 has ei ^¬ NEN forefoot portion 28 and a rear foot 29, which are interconnected by a midfoot portion 31. The forefoot Section 28 and the rear foot section 29 are formed over a large area, so that these sections 28, 29 allow a sufficient attachment surface for inclusion in the construction of a shoe sole 21. The contour shown is not absolutely necessary. Rather, individual strip-shaped elements may also be provided which extend, for example, into the forefoot part 23 and the rearfoot part 24.

The sole element 22 has a bow 33, through which an arcuate recess 34 is formed. Thereby, the central portion 31 is reduced to a web-shaped portion. This web-shaped midfoot portion 31 lies in the region of the fourth beam 16 of the foot 9. Alternatively, this web-shaped portion 31 can also extend up to the fifth beam 17 of the foot 9. By the web-shaped configuration of the metatarsal portion 31 allowing the midfoot portion 31 forms a shoe joint which acts in the area of the fourth beam 16 of the foot 9 which means that the forefoot part 23 to the rear foot ^¬ part 24 along the axis of the central web a rotational movement or torsional movement can perform. Furthermore, this arch 33 allows the arch of the foot to be extended during the rolling motion, for example, by increasing the distance between a proximal end 36 of the arch 33 and a distal end 37 of the arch 33 between the forefoot part 23 and the rearfoot part 24. The midfoot portion 31 may allow this movement, but an extension of the midfoot portion 31 is largely prevented. For this purpose, it is preferably provided that the midfoot portion 31 has a stiffening element 39, on the one hand to allow a certain elasticity with respect to the extension and the shortening of the forefoot portion 28 to the rear foot 29 and on the other hand relatively stiff in the midfoot portion 31, whereas the torsional ability of the forefoot portion 28 relative to the hindfoot portion 29 in turn made ^¬ light.

In Figure 4b, the sole element 22 is shown detached from the arrangement to a shoe sole 21. This sole element 22 can be provided as a separate insert for installation in a shoe sole 21 who ^¬ . Likewise, this sole element 22 in a soft elastic Material are involved, so that this sole element 22 is formed as a separate insole.

In the direct installation of the sole element 22 in the shoe sole 21 is preferably provided that extends within the arc 33, ie in the arcuate recess 34, an elastic material on the shoe sole to the upper of the shoe, so that a disability-free extension and shortening and Raising and lowering of the arch of the foot during a rolling process is possible. The sole element 22 can be poured over the forefoot section 28 and the rear foot section 29 into further components of the shoe sole 21. Likewise, these sections 28, 29 glued, sewn or the like.

FIGS. 5a to 5c show an alternative embodiment of the sole element 22 to FIGS. 4a and 4b. This sole element 22 is preferably designed as a separate component of the shoe sole and can be inserted or integrated in this. The basic structural design of the sole element 22 is retained in this embodiment, wherein it is provided deviating that the forefoot portion 28 and the rear leg 29 in the contour are at least partially adapted to the arch of the foot. Thus, both the forefoot portion 28 and the rearfoot portion 29 each have an upwardly curved portion 41, 42, which comprise a smooth transition to the midfoot portion 31 with its preferably arranged thereon stiffening element 39. This area can be extended downward to form, for example, a fixing element 61 which engages the shoe sole 21 to form an anchorage.

In addition, it is provided in this embodiment that a vault support 45 spans the arch 33 and medial to the forefoot portion

28 and rear foot section 29 extends. In an overlap region 46, the arch support 45 is the forefoot portion 28 and rearfoot portion

29 attached. This allows the proximal and distal ends 36, 37 of the arch 33 to continue to shorten and lengthen their distances. In addition, the freedom of movement remains Flattening and raising the arch of the foot through the vault support 45 obtained or even supported thereby. As soon as a flattening of the arch support 45 is initiated, this acts on the forefoot section 28 and the rear foot section 29, so that an extension of the stiffening element 22 takes place medially. The arch support 45 is preferably configured in a strip shape and adapted to the contour of the arch of the foot. This is evident in particular from FIG. 4a.

FIG. 6 shows a modified embodiment of the sole element 22 relative to FIGS. 5a to 5c. This sole element 22 additionally has a force storage element 49 which preferably medially engages the forefoot section 28 and the rear foot section 29. As a result, the extension and shortening of the arch 33 can be specifically controlled at its outer ends 36, 37. This power storage element 49 thus allows adaptation to weight classes. In addition, adaptation to different foot shapes may still be possible. This is preferably arranged interchangeable therewith and designed, for example, as a rubber-elastic band, as a spring element or the like.

FIGS. 7a and 7b show a further alternative embodiment of a sole element 22 to FIGS. 4a, 4b, 5a to 5c and 6a, 6b. This sole element 22, seen in plan view, has a contour of δ. For example, the rear foot section 29 is O-shaped, that is to say that no stiffening material is provided in the inner region of the rear leg section 29. In the area of the midfoot portion 31, a taper is provided in order to maintain the web-shaped Ausgestal ^¬ tion of the midfoot portion 31. The forefoot portion 28 is formed for example hook-shaped. By this embodiment, in turn, the sheet 33 and its arcuate recess 34 is realized. The rear foot section 29 is arched outwards and curved ge ^¬ to allow a support and guidance for the heel. The forefoot section 28 is located, for example, in the region of the first beam 10 and is connected via the midfoot section 31 to the lateral region of the rearfoot section 29. This extends along the fourth and fifth beams 16, 17. During a rolling movement, the rear foot section 29 is loaded, for example, in the region 51. This Area serves to counteract premature kinking of the foot 9 when occurring. Thus, this area 51 forms an anti-pronation support. This region 51 is also provided as part of the sole element 22 according to FIGS. 4 a to 5 on the arch support 45. As soon as a force acts on this region 51, a flattening of the initially proximal region 51 of the arch 33 and then a flattening of the distal region of the arch 33 occur, whereby a region 53 on the forefoot part 28 causes an evasion movement in the direction of the front toes of the foot 9. the distal end 37 of the arch 33 moves away from the proximal end 36. At the same time there is a flattening in the area 55. Thus, this sole element 22 can support a load on the longitudinal arch as well as transverse arch of the arch of the foot.

This sole element 22 can also be configured as an insole. In this case, for example, anchoring ribs or fixing elements 61 may be provided which engage in further components of the shoe sole 21 in order to fix the insole therein. Likewise, these fixing elements 61 may also be permanently provided in a shoe sole 21 when the sole element 22 is incorporated.
