Field of application of the invention

The invention relates to an insert for a shoe, in particular for a sports shoe, which extends at least in the forefoot, preferably in the entire foot, the sole.

Characteristic of the known state of the art

For shoes in general, and in particular for sports shoes, such as athletic shoes, hiking boots, golf shoes o. The like., It is important to design the shoe so that the risk of a kinking of the foot to the side and thus the risk that it tears ligaments or strains can come as low as possible. This risk of kinking the foot to the side is greater, the greater the respective acting on the foot sideways tilting moment and the smaller the other hand, the resistance of the shoe is against the lateral tilting moment. These two factors, namely the tipping moment on the one hand and the resistance of the shoe to the tipping moment on the other hand, are, apart from the external conditions, mainly due to the design of the shoe:

(1) First of all, the larger the side-rated force component, that is, the tilting force acting on the foot, the greater the tilting moment. This tilting force is largely due to the outer, d. H. shoe-independent load conditions, given that are particularly pronounced in the operation of sports, which is why it is relatively common in sports tears or strains.

(2) Further, the larger the tilting moment, the larger, in physical terms, the rocker arm, i. the farther the foot is from the ground. This means that the tipping moment under otherwise constant conditions becomes greater, the thicker the shoe sole is.

(3) Whether a given tilting moment can actually cause tilting and thus buckling of the foot to the side, but not only depends on the absolute height of the tilting moment, but also on the moment of resistance that the shoe einet) opposes lateral tilting. This moment of resistance is the greater, the more stable the shoe sole side is; d. H. a larger lever arm applies the sole against bending in the sole transverse direction, which means bending about a bending line which is parallel or approximately parallel to the longitudinal direction of the sole.

Assuming the above factors, then a very thin and stiff shoe sole would be ideal to minimize the risk of the foot kilting sideways. For if the shoe sole is sahr thin, there is a smallest possible overturning moment, and if the shoe sole is very stiff, there is a high moment of resistance, however, that the overturning moment can actually cause a lateral tilting. However, such a shoe sole is by no means ideal, because there are other requirements regarding the properties which a shoe should have:

Although the wearer of such a shoe with a very thin and stiff sole could stand well and safely on level ground, i. such a shoe would give the wearer good stability on level ground, however, the wearer of such a shoe could run poorly and unsafe with this shoe, and besides, he would not have good stability on uneven terrain ground, because the stiff sole of such a shoe would do not conform to an uneven floor and make a rolling movement of the shoe sole impossible during running on the floor. In order to allow the wearer of the shoe a good and safe running by a good rolling movement of the shoe sole on the ground, the shoe sole must be which and flexible. This requirement, the shoe sole is not rigid, but to make soft and flexible, but pulls for the following reasons, the further demand that the shoe sole may not be made thin, as in the above statements to reduce the risk of kinking of the foot is desirable, but rather should be made thick:

Namely, if a soft and flexible shoe sole is thin, then punctual pressures acting from below on the shoe sole and caused for example by stones, bumps o. The like., Transmitted through the shoe sole punctually on the sole of the wearer, which of course extremely uncomfortable to unpleasant. In order to mitigate such transmission of punctual pressure on the sole of the wearer's foot as much as possible and even prevent, it is therefore necessary to make the soft and flexible shoe sole needed for a good Abrollbewepung as thick as possible

 Thus, there are two conflicting demands with regard to the training of the shoe sole:

(a) On the one hand, the sole should be as thin and rigid as possible in order to minimize the risk of lateral kinking of the foot and thus the risk of ligament tears and strains.

(b) On the other hand, the sole should be as soft, flexible and thick as possible in order to ensure a smooth running movement and a secure footing on uneven ground and to prevent a transfer of punctual pressure from the ground as far as possible.

Although prior art shoe soles are known which have a stiffening insert, but is based on proposals for these known stiffening deposits neither the object to create a shoe sole, with the two aforementioned conflicting requirements are met, nor is with these deposits a solution to this problem provided:

British patent GB-A-1257 524 discloses a spiked stiffening insert of Motall or plastic material embedded in the shoe sole and intended especially for golf shoes. The object underlying this stiffening insert is to solve the problems of spike retention and foot isolation from spike pressure when using lighter, softer, and more flexible zellike sole materials. In addition, in such sole materials uncontrolled bending of the shoe, in particular an uncontrolled torsional bending of the middle part should be avoided in order to avoid a reduction in Fußkomforts and early deformation of the upper shoe. The solution to this problem, as far as the present case is of interest, is that the generally flat insert extends over the entire length of the shoe sole and all spikes of the forefoot are attached thereto, the attachment points of the spikes form slight dents on the insert. By this stiffening insert, therefore, not only the desired transverse reinforcement in the forefoot of the shoe sole is achieved, but the forefoot is stiffened at the same time in the longitudinal direction of the sole, whereby the rolling movement of the shoe sole during running is undesirably difficult.

US-A-4439937 discloses a stiffening metal insert which extends from the middle part of the forefoot part of the shoe sole backwards to the rear end of the heel and has the purpose of forming a support in the joint or instep region. The front part of the forefoot of the shoe sole, however, is expressly released from the stiffening insert so that it remains vertically flexible, as is required for a good rolling movement, but which has the disadvantageous consequence that only a small lateral stability is present.

Finally, from the European patent application EP-A-44549 a molded sole made of soft elastic plastic or rubber materials with a puncture resistant hard elastic insert, for example made of sheet steel, which is mainly intended for construction safety shoes, which should provide security against the penetration of nails by the shoe sole , The stiffening insert, which extends in the embodiment of interest here over virtually the entire length of the shoe sole, is formed and inserted into the shoe sole, that the toe area for supporting a toe steel cap and the Gelenkbereinh for supporting the ankle each directly below By contrast, while the remaining part of the forefoot area and the heel area of this insert are recessed so that they can be consistently covered by a layer of soft-elastic sole material, improved foot comfort in the ball and heel area is achieved over the use of a stiffening insert which extends everywhere directly under the insole. These recessed areas of the stiffening insert are formed in that the material of the insert at the transition from the respective elevated to the respective recessed area along bending lines which extend transversely to the sole longitudinal axis, is bent stepwise. However, this bending line does not substantially alter the stiffness ratios of the insert, so that the insert causes stiffening of the sole in substantially the same extent in the transverse and longitudinal directions, thereby hindering the rolling movement of the shoe sole to the extent that the transverse stiffness is obstructed is increased.

Object of the invention It is the object of the invention to increase the utility value properties.

-4- 290 803 Presentation of the veson of the invention

The invention is based on the requirement for a shoe, in particular for a sports shoe, which extends at least in the forefoot, preferably in the entire region of the sole, to create an insert in which the risk of lateral kinking of the foot and thus the risk of torn ligaments and -Zerrungen is as low as possible and at the same time allow an excellent smooth running movement of the shoe sole with optimal stability. According to the invention, this object is achieved in that the insert is bendable, at least in the forefoot area in the sole device, in particular in the respective Abrollhereich the sole, bending stiff, however, in the longitudinal direction of the sole vertically bendable.

A particularly preferred embodiment of the insert according to the invention is characterized in that it extends the insert over substantially the entire sole length and is well-twistable in the sole longitudinal direction from the heel to the big toe. Such an insert allows for twisting the foot, as required for example in many athletics sports, golf, tennis and the like.

Weite 'iii is dio deposit according to the invention very particularly preferably designed elastically resilient, whereby the shoe sole essentially always goes back to its original position by itself.

Finally, the insert according to the invention in its particularly preferred embodiment is designed to be pressure-resistant perpendicular to the sole plane, which is therefore very important because this punctual pressures are distributed from the bottom to the total area of the insert, so that pressures of small stones, bumps o. Like. Not selectively transferred to the sole of the foot. A very particular preferred and highly practicable embodiment of the insert according to the invention, which has all the above advantageous features, is characterized in that the, in particular one-piece, insert of hard, resilient plate material and at least in the forefoot, preferably over substantially the entire sole region, a transverse, in particular perpendicular, extending to the sole longitudinal direction transverse profiling, which preferably extends over the entire width of the insert, wherein the hard, resilient plate material preferably metal and / or plastic plate material, preferably steel sheet, particularly preferably spring steel sheet, is. Such an insert according to the invention, which is excellently suited for the practice of sole and shoe production, combines in particular the following advantageous properties:

(1) High lateral stability, since the cross-profile of the insert has a high flexural rigidity in the profiling direction, i. in the sole transverse direction lends, insuesondera in the respective Abrollbereich;

(2) very good vertical flexibility in the sole longitudinal direction, especially in the rolling motion, since the cross-profiling of the insert imparts a high flexural softness perpendicular to the profiling direction and perpendicular to the plane in which the profiling runs;

(3) high torsional ability about the sole longitudinal direction from the heel to the big toe, since the cross-profiling allows twisting of the individual cross-profiles relative to each other about an axis perpendicular to the individual profiles and in the common plane of the profiles;

(4) good pressure distribution due to the compressive rigidity of the hard plate material constituting the insert, such as steel, since this hard plate material distributes puncture pressures acting from below to the total area of the insert;

(5) excellent resilience, since the resilient plate material springs back into its original position due to its spring characteristic, so that a shoe sole provided with the insert according to the invention always assumes its original shape.

The high lateral stability of the insert according to the invention in conjunction with the good pressure distribution allows a very

flat design of the shoe soles provided with it, o. h. the production of thin soles without significant tilting effect, since the tipping moment due to the small thickness of the sole is as small as possible and the moment of resistance to tipping as a result of the high lateral stability is as large as possible, while providing a high comfort for the foot, dapunktuelle pressures from the ground are not selectively transferred to the sole of the foot and the foot a slight

Rolling while running is possible, and further wherein for adaptation to uneven floors, a thin layer of

soft-elastic sole material on the underside of the insert is sufficient (high stability).

Investigations have shown that such insert of spring steel invention minimum 5 million Bending dimensionally stable, what z. B. means that the deposit in about 660 golf tournaments stable and functional

remains.

A formed as a one-piece, profiled plate insert, especially with sole outline, on the one hand as such

rational and inexpensive to produce, and on the other hand, it can also be rationally and inexpensively integrated into the sole of a shoe. These advantages also largely arise when the orringungsgemäße insert from a

Composite layer material is made, which consists of different material layers, such as metal and Plastic. In this case, they may consist of separate in sole transverse direction strip-shaped areas, which through the Plastic layer are hingedly interconnected resiliently. The twistability of the insert from the heel to the big toe can be further increased if desired

be that the insert instead of the transverse profiling in the joint area and / or heel area in the

Sohlenlängsrichtung extending longitudinal profiling has. Such a longitudinal profiling is also in the joint area for

the support of the ankle beneficial.

Although, as already mentioned, it is preferable to form the insert so that it covers substantially the whole Area of the sole extends, it may also be sufficient in some cases, when the deposit over substantially the entire Width and / or extends over substantially the entire length of the forefoot, since this already most of the

advantages set out above.

The hard, resilient plate material may have a thickness between 0.1 mm and 1.5 mm, preferably between 0.3 mm and 0.8 mm,

to have.

The transverse and / or longitudinal profiling can, in particular in cross-section grooved, Riefen-, ribs, trough, wave, riffel- or

bead-shaped, preferably meander-shaped, trapezoidal, zig-zag or meander-like.

The direction of profiling is understood to mean the direction in which such profiling is rolled, drawn,

extruded or the like is, that is, for example, in a groove-shaped profile in cross-section, the groove longitudinal direction a single groove.

Preferably, the width of the periodically repeating profile cross-section elements is 3mm to 20mm, preferably

6mm to 16mm, more preferably 8mm to 13mm.

To further increase the anchoring ability of the insole in a sole, it is, although the insole according to the invention

Because of the profiling itself already has an excellent anchoring ability and therefore in the vast majority

Cases of such an increase is not required, it is possible to form the profiling so that they in the profiling direction

wavy, serrated, grooved, grooved or fluted is formed or any other, extending transversely to the profiling direction

Has secondary profiling. In order for the pressure of the foot to be transmitted even better to the ground, the insole can, in particular, be used as a one-piece Plate is formed,. a predetermined foot area or in several predetermined foot areas one after the Having bottom to gerichtcite depression, preferably in the area of the big toe, the football and / or the Heel, this recess, so that it performs the above function particularly well, preferably a flat or

has flat well bottom.

So that the plastic during foaming o.dpl. can distribute well on both sides of the deposit, the deposit can with Be provided through holes for the plastic material, which are distributed over the surface of the insert, preferably with

one or more spray channels for the injection molding of the plastic material and / or with a multiple or plurality of

Through openings, which can be in particular breakthroughs. The insert according to the invention makes it possible in an outstanding manner that nubs or spikes are non-releasably attached thereto

or by attachment means, which are provided on or in the insert, are replaceable attachable. This virtually eliminates any mounting and attachment problems otherwise associated with the attachment of dimples or spikes to a normal sole.

In particular, the aforementioned fastening means provided in the insert threaded holes or on the insert

attached thread inserts sen. A particularly stable, especially directionally stable, attachment of the knobs or spikes on the insert can be achieved according to the invention in that the foot parts of the knobs or spikes or

Fasteners, such as threaded inserts are secured in recesses of the insert and attached to the Support side walls of the wells, preferably form-fitting with the adjacent side walls of the wells

fit together and / or are fixedly attached to these side walls, which depressions are preferably the profile depressions formed by the transverse and / or longitudinal profiling. The spikes may also be attached in other ways, e.g. By riveting or welding.

The insert according to the invention may also consist of a composite panel material, which several to an integrated Composite structure has interconnected layers, of which at least one layer has the Querprof ilierung,

preferably consists of the transverse profiling. Such a composite structure allows to combine the advantages of different materials.

For example, the composite panel material may comprise a first layer consisting of a planar, preferably

non-profiled flexible resilient plate material, and a second layer formed as a tread layer consisting, for example, of individual juxtaposed profiles bonded by gluing, scorching or the like to the resilient plate material so that the first and second layers become one Composite material are integrated.

This type of construction makes it possible, for the first layer, to perform the function of an elastic articulation of the profiles

has to use a particularly resiliently flexible and thin material, for example Teflon or very thin spring steel, in contrast, for the second layer, which in particular has the function of giving the insert a high lateral stability, a particularly rigid and pressure-resistant material, such as Stainless steel or rigid plastic material to use.

By a composite sheet material, it is also possible to the insert according to the invention special special properties

which can not be achieved by a single-layer plate material or only with great difficulty. Thus, by juxtaposed rectangular profiles or U-profiles as cross-profiling in a composite plate material a

End position can be obtained, which allows only bending the sole up, but not down, which, for example Gives football boots particularly good shooting characteristics. Although the insert according to the invention in principle also used as an "insole" or as an inserted midsole

is preferred, it is preferably formed as an insole or firmly connected to the sole to keep them stable in the

Integrate the overall structure of the sole and thus of the entire shoe, resulting in both by gluing to the sole or Vulcanization can be seen on or in the sole as well as by forming the insert with sole material. The insert according to the invention may according to the invention be formed as an insole that the profiling hollow or

-intermediate spaces of the transverse profiling and possibly provided in certain embodiments. <

Longitudinal profiling and other depressions o. The like. Through a, preferably permanently connected to the insert Filling material are filled so that insert and filling material are preferably combined to form a composite material whose upper

and / or lower surface is flat.

With the invention, a sole for a shoe is further provided, which is an insert according to the invention

which is integral with the sole or forms part of the sole, or in which the sole is an insole of the type specified above or is firmly connected to such an insole. In such a sole, the

Insert according to the invention foamed with plastic, molded, encapsulated or otherwise formed or in a Plastic material be vulcanized, said plastic material at least part of the sole or the Ausfüllmasse

or the entire filling compound forms.

With the insert according to the invention, insole or sole, virtually all types of shoes can be provided, wherein

The term "shoes" in the present specification also includes boots, in particular boots, boots, rubber boots and the like, in addition to shoes in the strict sense, such as shoes, high shoes, etc. The shoes can be made by using the insole, insole or sole, otherwise be made very inexpensive.

In addition to the above-mentioned advantages, the high lateral stability of the insole, insole or sole according to the invention provides support and protection of the arch of the foot as well as protection in the ball area, in particular also against burning during running, the elastic resilience of the insole and the like. causes the foot less fatigued.

The insole, insole or sole of the invention is advantageous for normal footwear such as street shoes, and is particularly advantageous in athletic footwear such as, but not limited to, athletic footwear, jogging shoes, indoor sports footwear, recreational sports footwear, golf shoes , Tennis shoes, high jump shoes, mountain boots u. Like. And because of the excellent properties that it gives the shoe, not only use-promoting and health-protective, but also performance & doping effects resulting from the individual properties, such as increased stability, connectivity, elastic Rückstellfähigtait etc. To give just one example, among golf shoes, among other things, an improved impact quality due to the improved stability, the high Abrollbeweglichkeit and good torsional ability. The high jump can be, as experiments have shown achieve a greater jump height. In mountain shoes, the transmission of pressures from below, which is particularly critical because of the soil conditions, such as scree, is significantly reduced, while at the same time significantly improved because of the possible flat sole construction of the close contact with the ground and the risk of injury to the feet is significantly reduced. This significant reduction in the risk of injury and improvement of the tight ground contact is incidentally in all sports a very important advantage of the invention.

such parts, which are provided with reference numerals in a figure, but are not explained, to refer to the explanations of these parts with reference to previous figures.

Reference is first made to Figure 1, which is a plan view of a first embodiment of an insert 1 according to the Invention shows. This insert 1 is made in one piece from hard, resilient plate material, preferably from Spring steel, and extends over the entire sole area, that is, it has the outline of a substantially Insole, as shown. The insert 1 is verschen over its entire surface with a transverse profiling 2, extending in the transverse direction Q of the sole and

extends perpendicular to the longitudinal direction L of the sole. A partial perspective view of this transverse profiling 2 is illustrated in the left, lower part of Figure 1. Thereafter, the transverse profiling 2 has a trapezoidal meandering profile with rounded

Profile edges 3 are shown in FIG. 1 for characterizing the profile direction and the profile period P,

wherein the distance between two profile edges 3 shown in Figure 1 of the half profile period 1/2 Pentspresents, since the flanks of the trapezoidal cross-profiling 2 differ only slightly from the vertical, so that the two profile edges 3, which each define a profile edge, in the plan view of FIG From above practically coincide to a line.

Of course, in Figure 1 and in the other figures, only a few of the illustrated profile edges 3 with a reference numeral

Provided.

As is shown in FIG. 1, the profile period P indicates the width of the periodically repeating profile cross-section elements

in the present case, this means the width of a trapezoidal elevation A plus a trapezoidal depression B.

FIG. 2 shows a further embodiment of an insert 1, which differs from the insert according to FIG

distinguishes that the cross-profiling 2 has a larger profile period P and that the insert is provided with through-holes 4, which are designed in particular as breakthroughs. These passage openings 4, over the surface of the

Insert 1 are distributed, serve as passages for plastic material during foaming, Umspitzen, Umgießen or

other forming the insert with plastic for the purpose of Integriereiis the deposit in a shoe sole.

In addition, in Figure 2, the longitudinal axis C-D, the roll axis E-F and the transverse axis G-K of the sole, in which the insert. 1

is integrated, drawn.

The cross-profiling 2 of the insert 1 nor Figure 2 preferably has the Profilierungsform shown in Figure 1, below, they can

but also have a different profiling shape, for example one of those shown in FIGS. 4, 5 and 6

Profiling forms. FIG. 3 shows a plan view of a third embodiment of a liner 1 according to the invention and a longitudinal section

by this insert, which differs in several ways from the embodiments according to FIGS. 1 and 2:

(A) While in the forefoot 5 and the heel area 7 each profiling a transverse profiling 2 is provided, the hinge portion 6 a extending in the longitudinal direction of the insert 1 longitudinal profiling 8, which at both longitudinal ends of the heel portion 6 via a transition transverse profiling 9 gradually the transverse profiling 2 of the forefoot 5 and the heel area 7 passes.

(b) Both the transverse profiling 3 and the longitudinal profiling 8, as well as the transition transverse profiling 9 is formed as a zig-zag profile, as the cross-sectional view in Figure 3 shows. This profile is shown in perspective in FIG. 6 in a partial view.

(c) Finally, the insert 1 of the embodiment of Figure 3 has through holes 10 for the attachment of threaded inserts 11 for screwing in nubs or spikes 12 (see Figure 3, right, top). In order to be able to fix the threaded inserts or inserts 11 s'.abil to the insert 1 of FIG. 3 via a wide foot 14, flat regions 13, that is to say regions without the transverse profiling 2, are provided around the through-holes 10. The present type of attachment of studs or spikes is only one example of the many possibilities of a fixed or releasable attachment of the same to the insert of the invention.

As already indicated, FIGS. 4, 5 and 6 show perspective partial views of profiles which, instead of the profile shown in FIG. 1, bottom left, can be used as transverse profiling 2 and / or longitudinal profiling 8 as well as transitional profiling 9. It should be noted here that the profiles shown are only a few profiles of a ι UIIe of different profiles, which sine for the insert according to the invention *. In detail, the FIG ^r. 4 shows a rectangular meander, while Figure 5 shows a trapezoidal meandering profile with a secondary profile 15 which is smaller than the trapezoidal meandering and their profiling direction perpendicular to the profile direction of the trapezoidal Mäanderprofils. As already mentioned, FIG. 6 shows a zig-zag profile. The profile edges 3 may be more or less rounded, so that thereby the profiles according to Figures 4 and 5, if desired, in groove profiles with grooves of semicircular or oval or arcuate cross-section can pass. The profile period P is preferably in the range between 3 mm and 20 mm, preferably in the range between 6 mm and 16 mm and particularly preferably in the range between 8 mm and 13 mm, while the profile height H is preferably in the range between 1 mm and 5 mm, preferably in the range between 2 mm and 3 mm , is, wherein the hard, resilient plate material from which the insert 1 is made, preferably made of metal or plastic material, particularly preferably made of spring steel. The thickness of this plate material depends on the type of material and is generally preferably in the range between 0.5 mm and 1.5 mm.

FIG. 7 shows an insert 1, which has a transverse profiling 2 in the forefoot region, but has a continuous longitudinal profiling 8 in the joint and heel region and is provided with through holes 10 for directly attaching spikes 12 or for attaching fastening means for spikes 12.

FIG. 8 shows a plan view of a further embodiment of an insert 1 according to the invention, the transverse profiling 2 of which is provided in the forefoot region 5 and in the heel region 7 between a longitudinal profiling 8 in the joint region 6 * is interrupted by a plurality of recesses 16 directed towards the bottom , The depressions 16 may be circular. The three depressions 16 provided in the forefoot region 5 are in the region of the big toe and the foot bones, while the rear depression 16 is located in the region of the heel.

These depressions 16 are used to better transfer the foot pressure on the floor. As Figure 9, which shows a section along the line M-N of Figure 8 through which one of the recesses 16 illustrates, the bottom 17 of the recess 16 is flat and at the lowest profiling level, thus closest to the floor.

FIG. 10 shows a sole 18 with an insert 1 represented by dashed lines which extends only over the forefoot region 5 and

is continuously provided with anorQuerprofilierung 2 Is. In the longitudinal section dt Figure 11 lunge of the line ST through the sole 18 of Figure 10 of the sole 18 only the outsole is shown, while the plastic material in which the insert 1 is foamed and which is fixedly connected to the outsole, is omitted for purposes of illustration ,

Figures 12 and 13 show, in a schematic way, how a liner 1 in the overall structure of a sole 18 preferably

is integrated, namely between the outsole 19 on the one hand and the insole 20 and the footbed 21 on the other hand, wherein the heel part 22 in the case of the flat sole 18 of Figure 12 may be a wedge insert.

Both the insert 1 of the sole 18 of Figure 12 and that of the sole 18 of Figure 13 has in the forefoot 6 and

in the sales area 7 a continuous Querp 'jfilierung 2, while in the hinge region 6 a longitudinal profiling 8 is provided. In the heel shoe according to FIG. 13, the longitudinal profile 8 is curved in an ascending manner, as seen at 23, and passes over a steeply sloping region 24 of the insert 1 at the beginning of the heel 22 into the transverse profiling 2 of FIG

Sales area 7 via. In the sole 18 according to FIG. 12, spikes 12 are provided in the transverse profiling 2 of the forefoot region 5 and the heel region 7

hindurchdeckt through holes of the insert 1 and at their foot parts 25, which are perpendicular to the

Side flanks support the transverse profiling 2, for example, welded to the insert 1 or in any other way at this Insert 1 attached. For the training of Soh'en 18, which are provided with an insert according to the invention, all

conventional materials are used, with other common deposits, such as the heel wedge at Keilschuhnach Figure 12, together with the insert 1 into the sole 18 can be foamed.

In Figure 14, finally, a partial cross-section through an insert 1 according to the invention is shown, which consists of a Composite panel material consisting of several layers 26; 27; 28 is constructed by gluing to an integral Composite material united are: The bottom in Figure 14 layer 28 consists of adjacent square box sections 29, which in a very

small distance U of, for example, 0.1 mm or less away from each other or even close to each other are arranged. These box profiles 29 are made by means of the layer consisting of adhesive 27 with a resiliently flexible, flat

Plate material existing layer 26 firmly connected. The particular advantage of the insert 1 of Figure 14 is that the insert only in the direction of the arrow X upwards, not

However, in the opposite direction can bend down, since in the latter case, the side parts 30 adjacent

Support box sections 29 against each other. A shoe whose sole is provided with such an insert is suitable

For example, especially good as a football boot, as this deposit an undesirable bending of the sole down to

Balling, for example, when shooting at the goal prevented. The plate material constituting the layer 26 may be made of, for example, spring steel or Teflon and have a thickness V, je

preferably between 0.1 mm and 2 mm, while the box profiles 29, which may for example be extruded from a high-strength aluminum alloy, may have a side length Wim of preferably 3 mm to 5 mm. Optionally, the box profiles 29 or any other profiles, in such a

Composite plate material are provided, if they are made of metal, provided with a soft plastic coating

be, which largely dampens the noise generated when hitting the profiles.

In Figs. 15, 16 and 17 are greatly enlarged and not necessarily to scale partial longitudinal sections through three Embodiments of an insole 31 are shown, which has an insert 1 with transverse profiling 2 and a profiling hollow.

or spaces 32 filling filling mass 33 (shown hatched) includes. This filling compound 33 fills the

Profiling hollow spaces 32 so that the upper surface 34 and the lower surface 35 of the insole 31

are just.

The insert 1 and the Ausfüllmasse 33 are preferably connected to a component firmly adhering to each other, for example

by gluing or scorching, wherein the insert 1, if it is made of metal, is preferably primed for adhesion improvement. The filling compound 33 can be or contain plastic and / or other filling material.

While in FIG. 15 the thickness of the insole 31 is equal to the height H of the insert 1, in the insole 31 according to FIG Thickness R of the filling mass 33 greater than the height H of the insert 1, so that on both sides of the insole 31 each thin Layers Y and Z of fill mass 33 are present over the insert 1. Layer Y can only be on one side,

preferably on the foot-facing side, in particular to improve comfort f ü:

the foot.

In the embodiment nr.ch Figure 17 results in an even more improved foot comfort by acting on the surface 34 of

the insert 1 and the filling compound 33 formed composite article 36 applied a thin insole 36festhaftend or loose

The insert 1 in FIG. 15, which has a trapezoidal cross-section 2 rounded in cross-section, can be, for example, the one in FIG Figure 1 shown deposit, in which, for example, the insert 1 primed spring steel sheet preferably of 0.2mm Material thickness with a Profilpertode P of 5 mm and a height H of 2.0 mm and with a fill mass 33 of

soft elastic plastic is made on both sides plan.

The insert 1 in Figure 16, which has a rillenförrr.lge transverse profiling 2 may be, for example, the insert 1 shown in Figure 2. And the insert 1 in Figure I7, which has a zig-zag-shaped cross-profiling 2, for example, the one shown in Figure 3 Insert 1, but preferably without the through holes 10 and without the flat portions 13 of Figure 3. In principle, the insole 31 may be made of any insert 1 according to the invention, wherein in the case of the insert 1

According to FIGS. 8 and 9, the depressions 16 can also be filled with the filling compound 33, which can also have impact-absorbing properties.

It goes without saying that the Ausfüllmasse 33 has a much lower hardness than the material of the insert 1, for Example, soft elastic and possibly also shock absorbing, so that the inventive properties of the insert 1 1

despite the Ausfüllmasse 33 are highly effective. The same applies to the plastic material with which a

Insert 1 can be transformed according to the invention.
