The shoe has a footbed, a covering layer on the footbed, a cushion region arranged in the footbed, in particular in the central foot, heel and/or toe region, and a midsole. The cushion region has a multilayer structure and has an upper soft layer, a central hard layer and a lower semi-hard layer. As a result, pressure and/or shear stresses of the foot can be reduced to a great extent. A correspondingly designed insert is also described. <IMAGE>

Description

Die vorliegende Erfindung betrifft einen Schuh, insbesondere für Diabetiker oder Rheumatiker, mit einem Fußbett, einer Deckschicht auf dem Fußbett, einem im Fußbett, insbesondere im Mittelfuß-, Fersen- und/oder Zehenbereich, angeordneten Polsterbereich und einer Zwischensohle.The present invention relates to a shoe, in particular for diabetics or rheumatics, with a footbed, a cover layer on the footbed, a cushion area arranged in the footbed, in particular in the midfoot, heel and / or toe area, and a midsole.

Derartige speziell abgepolsterte Schuhe sind bekannt. Sie finden im orthopädischen Bereich Verwendung, sind aber auch für Menschen konzipiert, die sehr schmerzempfindlich am Fuß sind, wie beispielsweise Rheumatiker. Darüber hinaus werden solche Schuhe von Diabetikern benutzt, die im Alter häufig an Nervenstörungen leiden, welche sich in einer Unempfindlichkeit des Fußes manifestieren. Druck oder Schmerz wird von solchen Menschen nur noch unvollkommen oder überhaupt nicht mehr wahrgenommen, so daß sich beim Tragen von normalem Schuhwerk hierdurch permanente Schädigungen des Fußes ergeben.Such specially padded shoes are known. They are used in the orthopedic field, but are also designed for people who are very sensitive to pain on the foot, such as rheumatics. In addition, such shoes are used by diabetics who often suffer from nervous disorders in old age, which manifest themselves in insensitivity of the foot. Pressure or pain is only imperfectly or no longer perceived by such people, so that permanent foot damage results when wearing normal footwear.

Beim normalen Gehen oder Laufen entsteht eine horizontal nach vorne gerichtete Bewegungskomponente des Fußes im Schuh, so daß der Fuß entsprechende Druck- bzw. Scherkräfte aufnehmen muß. Es ist gerade diese Bewegungskomponente, die den Fuß besonders stark beansprucht und zu den vorstehend erwähnten permanenten Schädigungen des Fußes bei Diabetikern oder zu Schmerzerscheinungen bei Menschen mit besonders empfindlichen Füßen, beispielsweise Rheumatikern, führt.During normal walking or running, a horizontally forward movement component of the foot is created in the shoe, so that the foot has to absorb appropriate pressure or shear forces. It is just this Movement component that stresses the foot particularly heavily and leads to the permanent damage to the foot mentioned above in diabetics or to pain symptoms in people with particularly sensitive feet, for example rheumatism sufferers.

Um diesen Erscheinungen vorzubeugen, hat man speziell gepolsterte Schuhe entwickelt, die in den am meisten gefährdeten Bereichen des Fußes, nämlich dem Mittelfuß-, Fersen- und/oder Zehenbereich, gepolstert sind. Es hat sich jedoch gezeigt, daß mit den bisherigen Entwicklungen gerade die durch die horizontale Vorwärtsbewegungskomponente des Fußes erzeugten Druck- und Scherbelastungen desselben nur unzureichend verringert werden können.To prevent these phenomena, specially padded shoes have been developed that are padded in the most vulnerable areas of the foot, namely the midfoot, heel and / or toe area. However, it has been shown that with the developments to date, the pressure and shear stresses generated by the horizontal forward movement component of the foot can only be insufficiently reduced.

Der Erfindung liegt die Aufgabe zugrunde, einen Schuh der eingangs beschriebenen Art zu schaffen, der einen besonders guten Tragekomfort bietet und insbesondere Druck- und/oder Scherbelastungen des Fußes bei Vorwärtsbewegungen desselben im Schuh abbaut.The invention has for its object to provide a shoe of the type described above, which offers particularly good wearing comfort and in particular reduces pressure and / or shear loads on the foot during forward movements of the same in the shoe.

Diese Aufgabe wird erfindungsgemäß bei einem Schuh der angegebenen Art dadurch gelöst, daß der Polsterbereich einen Mehrschichtaufbau besitzt und eine obere weiche Schicht, eine mittlere harte Schicht und eine untere mittelharte Schicht umfaßt.This object is achieved according to the invention in a shoe of the type specified in that the cushion area has a multilayer structure and comprises an upper soft layer, a medium hard layer and a lower medium hard layer.

Der erfindungsgemäß ausgebildete Schuh, bei dem es sich um jede beliebige Schuhart, insbesondere Sandalen, handeln kann, weist somit das als statisches Gerüst dienende bekannte Fußbett mit einer darüber angeordneten Deckschicht auf. In das Fußbett eingesetzt ist ein Mehrschichtpolsterbereich, der von oben nach unten eine weiche Schicht, eine harte Schicht und eine mittelharte Schicht besitzt. Dieser Schichtaufbau hat sich zur Lösung der vorstehend genannten Aufgabe als optimal erwiesen. Es wurde erfindungsgemäß festgestellt, daß die obere Schicht entsprechend weich ausgebildet sein und eine besonders geringe Rückstellkraft aufweisen muß, damit sich das individuelle Fußbett des Patienten ausbilden kann. Die mittlere Schicht muß entsprechend hart ausgebildet sein und eine hohe Rückstellkraft aufweisen, um für den Halt bzw. die Festigkeit des Polsterbereiches zu sorgen. Die untere Schicht wiederum ist mittelhart ausgebildet und besitzt eine mittelgroße Rückstellkraft, um zu ermöglichen, daß sich ein tiefer stehender Knochen des Fußes tief in die Polsterung einarbeiten kann. Hierbei kann sich die mittlere Schicht aufgrund eines tieferstehenden Knochens in die untere Schicht drücken, so daß die untere Schicht eine entsprechende Schutzfunktion übernimmt und selbst für Fälle mit besonders tiefstehenden Knochen entsprechende Polsterfunktionen übernimmt.The shoe designed according to the invention, which can be any type of shoe, in particular sandals, thus has the known footbed serving as a static scaffold with a cover layer arranged above it. A multi-layer cushion area is inserted into the footbed, which has a soft layer, a hard layer and a medium-hard layer from top to bottom. This layer structure has proven to be optimal for solving the above-mentioned task proven. It has been found according to the invention that the upper layer must be made correspondingly soft and have a particularly low restoring force so that the patient's individual footbed can form. The middle layer must be made correspondingly hard and have a high restoring force in order to ensure the hold or the strength of the cushion area. The lower layer, in turn, is of medium hardness and has a medium-sized restoring force to enable a deeper bone of the foot to work deeply into the padding. Here, the middle layer can press into the lower layer due to a deeper bone, so that the lower layer takes on a corresponding protective function and takes over appropriate cushioning functions even for cases with particularly deep bones.

Durch den erfindungsgemäß vorgesehenen Mehrschichtaufbau des Polsterbereiches, der mindestens die vorstehend erwähnten drei Schichten besitzt, wird somit die Ausbildung des individuellen Fußbettes bei gleichzeitiger ausreichender Halterung des Fußes im speziell abgepolsterten kritischen Bereich und bei sicherer Abpolsterung selbst von tiefstehenden Knochen erreicht. Damit stellt die Erfindung aber eine wesentliche Verbesserung gegenüber den unvollkommenen Lösungen des Standes der Technik dar. Insbesondere werden bei einer Horizontalbewegung des Fußes im Schuh die dabei entstehenden Druck- und/oder Scherbelastungen des Fußes durch dessen elastische Führung durch die obere Schicht der Polsterung weitgehend gedämpft, wobei allerdings die mittlere Schicht dem Fuß einen ausreichenden Halterungseffekt verleiht, so daß der Fuß nicht im Fußbett "schwimmt". Derartige Druck- und/oder Scherbelastungen werden auch in bezug auf tiefstehende Knochen durch die untere mittelharte Schicht hinreichend gedämpft.Due to the multi-layer structure of the cushion area provided according to the invention, which has at least the three layers mentioned above, the formation of the individual footbed is achieved with simultaneous sufficient support of the foot in the specially padded critical area and with secure cushioning even of deep bones. However, the invention thus represents a significant improvement over the imperfect solutions of the prior art. In particular, when the foot moves horizontally in the shoe, the resulting pressure and / or shear loads on the foot are largely dampened by its elastic guidance through the upper layer of the padding , but the middle layer gives the foot a sufficient support effect so that the foot does not "float" in the footbed. Such pressure and / or shear stresses are also sufficiently damped by the lower, medium-hard layer in relation to deep-set bones.

Der Polsterbereich kann flächig begrenzt im Fußbett angeordnet und einem oder mehreren kritischen Fußbereichen zugeordnet sein. Diese kritischen Fußbereiche sind insbesondere der Mittelfuß-, Fersen- und/oder Zehenbereich. So ist bei einer speziellen Ausführungsform der Erfindung der Polsterbereich im Mittelfußbereich des Fußbettes angeordnet. Bei einer speziellen Ausführungsform erstrecken sich die obere und mittlere Schicht über das gesamte Fußbett, während die untere Schicht flächig begrenzt ist und insbesondere nur den Mittelfuß-, Fersen- und/oder Zehenbereich abdeckt. Hierbei wird das gesamte Fußbett durch die beiden oberen Schichten abgepolstert, während die untere Schicht, die eine Dämpfungs- bzw. Schutzfunktion für einen tiefsitzenden Knochen oder Entzündungen, Ulcera, Narbenbildung und offene Wunden bildet, nur im kritischen Bereich, in dem dieser tiefsitzende Fußknochen etc. auftreten kann, vorgesehen ist.The cushion area can be arranged in a limited area in the footbed and can be assigned to one or more critical foot areas. These critical foot areas are in particular the midfoot, heel and / or toe areas. Thus, in a special embodiment of the invention, the cushion area is arranged in the midfoot area of the footbed. In a special embodiment, the upper and middle layer extend over the entire footbed, while the lower layer is limited in area and in particular only covers the midfoot, heel and / or toe area. The entire footbed is cushioned by the two upper layers, while the lower layer, which forms a cushioning or protective function for deep-seated bones or inflammation, ulcers, scarring and open wounds, only in the critical area in which this deep-seated foot bone, etc. can occur is provided.

Das Fußbett selbst besteht beispielsweise aus der üblichen Konstruktion aus einer Kork-Latex-Mischung. Es besitzt eine oder mehrere Ausnehmungen für den Polsterbereich, wobei sich der Polsterbereich vorzugsweise durch das Fußbett bis zur Zwischensohle erstreckt. Auf der Oberseite des Fußbettes befindet sich eine übliche Deckschicht, vorzugsweise aus Sämisch gegerbtem Leder.The footbed itself consists, for example, of the usual construction made of a cork-latex mixture. It has one or more recesses for the cushion area, the cushion area preferably extending through the footbed to the midsole. On the top of the footbed there is a usual top layer, preferably made of chamois tanned leather.

Was die Dicke des Polsterbereiches anbetrifft, so besitzt die obere Schicht vorzugsweise eine Dicke von 1 - 3 mm, die mittlere Schicht vorzugsweise eine Dicke von 2 - 4 mm und die untere Schicht vorzugsweise eine Dicke von 5 - 7 mm. Besonders bevorzugte Werte für die obere Schicht sind 2 mm, für die mittlere Schicht 3 mm und für die untere Schicht 6 mm. Es versteht sich, daß die Dicke der Schichten in Anpassung an das Fußbett variieren kann. Die obigen Angaben sind daher Durchschnittswerte. Die relativ große Dicke der unteren Schicht ergibt sich daraus, daß diese ein Eindrücken der mittleren Schicht bei tiefstehenden Knochen etc. ermöglichen soll, jedoch nicht ein Durchdrücken bis auf die Zwischensohle.As for the thickness of the cushion area, the upper layer preferably has a thickness of 1-3 mm, the middle layer preferably 2-4 mm and the lower layer preferably 5-7 mm. Particularly preferred values for the upper layer are 2 mm, for the middle layer 3 mm and for the lower layer 6 mm. It will be appreciated that the thickness of the layers may vary to match the footbed. The above figures are therefore averages. The relatively large thickness of the lower layer results from the fact that this should enable the middle layer to be pressed in with deep-set bones etc., but not to be pushed through to the midsole.

Ein bevorzugtes Material für die Oberschicht stellt offenporiger Zellkautschuk dar. Mit diesem Material sind die gewünschten Eigenschaften, wie relativ geringes Rückstellvermögen zur Ausbildung des individuellen Fußbettes, erreichbar. Die mittlere, Im Vergleich zu den beiden anderen Schichten besonders hart und fest ausgebildete Schicht besteht vorzugsweise aus geschlossenporigem Zellkautschuk, der das geforderte hohe Rückstellvermögen besitzt, so daß die mittlere Schicht quasi als Tragschicht für den Schichtaufbau dienen kann. Die untere Schicht besteht vorzugsweise wiederum aus offenporigem Zellkautschuk, wobei jedoch dieses Material härter ausgebildet ist als das der oberen Schicht und im Vergleich zu den beiden anderen Schichten ein mittleres Rückstellvermögen aufweist, das größer ist als das Rückstellvermögen der oberen Schicht, jedoch kleiner als das der mittleren Schicht.A preferred material for the upper layer is open-pore cellular rubber. With this material, the desired properties, such as relatively low resilience to form the individual footbed, can be achieved. The middle layer, which is particularly hard and firm in comparison to the other two layers, preferably consists of closed-cell cellular rubber, which has the required high resilience, so that the middle layer can serve as a base layer for the layer structure. The lower layer preferably again consists of open-celled cellular rubber, but this material is made harder than that of the upper layer and, compared to the other two layers, has an average resilience which is greater than the resilience of the upper layer but less than that of the middle layer.

Das Fußbett ist vorzugsweise vorne und hinten zur Rolle geschliffen, um eine gute Schrittabwicklung zu gewährleisten.The footbed is preferably ground to a roll at the front and back to ensure good walking.

Die Zwischensohle des Schuhs ist beispielsweise als Starrsohle oder Versteifungssohle ausgebildet. Diese Ausführungsform ist insbesondere für Diabetiker geeignet, da hierdurch punktuelle Druckbelastungen gleichmäßig auf den Fuß verteilt werden. In Verbindung mit dem erfindungsgemäß vorgesehenen Polsterbereich kann hierdurch die gewünschte Druckentlastung des Fußes, insbesondere an den erwähnten kritischen Stellen erreicht werden. Bei besonders schmerzempfindlichen Füßen, beispielsweise bei Rheumatikern, empfiehlt es sich, eine derartige starre Zwischensohle durch eine weiche Zwischensohle zu ersetzen, die einen Puffereffekt erzeugt und möglicherweise auch einen Druckausgleich herbeiführen kann.The midsole of the shoe is designed, for example, as a rigid sole or stiffening sole. This embodiment is particularly suitable for diabetics, since it distributes selective pressure loads evenly over the foot. In conjunction with the cushion area provided according to the invention, the desired pressure relief of the foot can be achieved in this way, in particular at the critical points mentioned. In the case of feet that are particularly sensitive to pain, for example in rheumatics, it is advisable to cover such a rigid midsole with a soft midsole replace, which creates a buffer effect and may also cause pressure equalization.

Die Zwischensohle ist vorzugsweise in einem Hohlraum des Fußbettes angeordnet. Hierdurch kann sie besonders günstig am Fußbett befestigt werden, und der Schuh wirkt insgesamt weniger wuchtig, da dessen Höhe verringert wird. Darüber hinaus läßt sich diese Ausführungsform herstellungstechnisch besonders günstig verwirklichen.The midsole is preferably arranged in a cavity in the footbed. As a result, it can be attached to the footbed particularly cheaply, and the shoe appears less bulky overall, since its height is reduced. In addition, this embodiment can be implemented particularly inexpensively in terms of production technology.

Bei einer speziellen Ausführungsform der Erfindung ist zwischen dem Dreischichtaufbau des Polsterbereiches und der Zwischensohle eine vierte Schicht aus einem verformbaren Polstermaterial angeordnet. Es kann sich hierbei um ein verformbares thermoplastisches Polstermaterial handeln, das gut an das Fußbett anpaßbar ist, um die Rolle des Fußbettes vorne und hinten mitzugehen. Die Funktion dieser vierten Schicht besteht in einer weiteren Polsterung. Eine solche vierte Schicht kommt daher nur in besonderen Fällen zur Anwendung.In a special embodiment of the invention, a fourth layer of a deformable cushion material is arranged between the three-layer structure of the cushion area and the midsole. This can be a deformable thermoplastic cushioning material that can be easily adapted to the footbed in order to move the role of the footbed in the front and back. The function of this fourth layer consists of additional padding. Such a fourth layer is therefore only used in special cases.

Es versteht sich, daß das Fußbett im übrigen beliebig gestaltet und an die jeweiligen Fußformen angepaßt sein kann.It goes without saying that the footbed can be designed in any other way and adapted to the respective foot shapes.

Ergänzend sei noch erwähnt, daß der erfindungsgemäß ausgebildete Polsterbereich auch im Längsgewölbe des Fußbettes angeordnet sein kann. Eine solche Ausführungsform eignet sich insbesondere für einen Plattfuß oder einen Chacot-Fuß.In addition, it should also be mentioned that the cushion area designed according to the invention can also be arranged in the longitudinal arch of the footbed. Such an embodiment is particularly suitable for a flat foot or a chacot foot.

Eine weitere Polsterung des Fußes wird über den Schaft des Schuhs erreicht. So besitzt eine Ausführungsform der Erfindung einen Schaft, der von außen nach innen eine Lederschicht, ein Verstärkungsband, eine Zellkautschukschicht und eine Futterlederschicht aufweist. Dabei besteht die äußere Lederschicht vorzugsweise aus Nappaleder. Bei der Zellkautschuckschicht handelt es sich vorzugsweise um eine Schicht aus geschlossenporigem Zellkautschuk, wobei die Schicht vorzugsweise 3 mm dick ist. Das Futterleder ist vegetabil gegerbt und damit chromfrei.A further padding of the foot is achieved via the upper of the shoe. Thus, one embodiment of the invention has a shaft that has a leather layer, a reinforcing tape, a cellular rubber layer and a lining leather layer from the outside in. There is the outer leather layer preferably made of nappa leather. The cellular rubber layer is preferably a layer of closed-cell cellular rubber, the layer preferably being 3 mm thick. The lining leather is vegetable tanned and therefore chrome-free.

In Weiterbildung des erfindungsgemäß ausgebildeten Schuhs ist das Fußbett mit einer Längsgewölbestütze versehen. Eine weitere Ausführungsform zeichnet sich dadurch aus, daß das Fußbett eine Fersenschrägstellung aufweist. Vorzugsweise erstreckt sich hierbei die Fersenschräg-Stellung etwa über die Hälfte des Fersenbereiches des Fußbettes und steigt zum Innenrand des Fußbettes hin an.In a further development of the shoe designed according to the invention, the footbed is provided with a longitudinal arch support. Another embodiment is characterized in that the footbed is inclined at the heel. In this case, the inclined heel position preferably extends over approximately half of the heel region of the footbed and rises towards the inner edge of the footbed.

Besonders gute Ergebnisse werden mit einer Kombination beider Merkmale erzielt. Hierdurch wird in Verbindung mit der erfindungsgemäß vorgesehenen Polsterbereich mit Mehrschichtaufbau eine besonders gute Stützung des Fußes erreicht, weil ein punktuelles Anstützen, wie eine normale Längsgewölbestütze oder eine Sustemtaculum-Anstützung, vermieden wird, das zu Schmerzen führen kann. Mit der erfindungsgemäß gewählten Anstützungsart gelingt es, den Fuß des Erkrankten (Rheumatikers, Diabetikers) statisch wieder ins Lot zu bringen. Die erfindungsgemäß gewählte Lösung, die eine gesamtflächige Lösung darstellt, ist somit die konsequente Fortsetzung des vorgesehenen Polsterbereiches, mit dem ebenfalls punktuelle Beeinflussungen verhindert werden.Particularly good results are achieved with a combination of both features. As a result, particularly good support for the foot is achieved in connection with the cushion area provided according to the invention with a multi-layer structure, because selective support, such as a normal longitudinal arch support or a sustem tacular support, is avoided, which can lead to pain. With the type of support chosen according to the invention, it is possible to statically straighten the foot of the patient (rheumatic, diabetic). The solution chosen according to the invention, which represents a total area solution, is consequently the consequent continuation of the intended upholstery area, with which also selective influences are prevented.

Die vorliegende Erfindung betrifft ferner eine Einlage für einen Schuh, insbesondere für Diabetiker und Rheumatiker, die einen Polsterbereich mit Mehrschichtaufbau gemäß einem der vorangehenden Ansprüche aufweist.The present invention further relates to an insert for a shoe, in particular for diabetics and rheumatics, which has a cushion area with a multilayer structure according to one of the preceding claims.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels in Verbindung mit der Zeichnung im einzelnen erläutert. Es zeigen:

The invention is explained below using an exemplary embodiment in conjunction with the drawing. Show it:
Figure 1
the footbed of a shoe in a spatial representation;
Figure 2
the footbed of Figure 1 with a cut part to show the structure of the cushion area, on an enlarged scale;
Figure 3
a section through the shaft material of the shoe; and
Figure 4

Das in den Figuren 1 und 2 dargestellte Fußbett gehört zu einem Schuh, der für Diabetiker geeignet ist. Die übrigen Teile des Schuhs, mit Ausnahme eines Schnittes durch das Schaftmaterial, sind nicht dargestellt, da sie für die Erfindung keine Bedeutung haben und in üblicher Weise ausgebildet sein können. So kann es sich bei dem Schuh beispielsweise um eine Sandale handeln.The footbed shown in Figures 1 and 2 belongs to a shoe that is suitable for diabetics. The remaining parts of the shoe, with the exception of a cut through the shaft material, are not shown, since they have no significance for the invention and can be designed in the usual way. For example, the shoe can be a sandal.

Das Fußbett 1 besteht aus der üblichen Kork-Latex-Mischung und ist an die Form es Fußes angepaßt. Es ist muldenartig ausgebildet und weist auf seiner Unterseite einen mittleren Hohlraum zur Anordnung einer Starrsohle 8 auf. Auf der Oberseite des Fußbettes ist eine Deckschicht 4 aus Sämisch gegerbtem Leder angeordnet. Diese Deckschicht ist in üblicher Weise ausgebildet.The footbed 1 consists of the usual cork-latex mixture and is adapted to the shape of the foot. It is trough-shaped and has a central cavity on its underside for the arrangement of a Rigid sole 8 on. On the top of the footbed, a cover layer 4 made of chamois tanned leather is arranged. This cover layer is formed in the usual way.

Das Fußbett weist im Mittelfußbereich 3 (in den Figuren gestrichelt angedeutet) eine Ausnehmung auf, die einen Mehrschichtpolsterbereich aufnimmt. Dieser Mehrschichtpolsterbereich umfaßt drei Schichten, von denen sich die beiden oberen Schichten im wesentlichen über das gesamte Fußbett erstrecken und an den Fußbetträndern auslaufen, während die untere Schicht auf den Mittelfußbereich beschränkt ist. Die Deckschicht 4 erstreckt sich über den Polsterbereich, so daß sich auf der Oberseite des Fußbettes ein einheitlicher Abschluß ergibt. Auf der Unterseite stößt die untere Schicht 7 gegen die Starrsohle 8.The footbed has a recess in the midfoot area 3 (indicated by dashed lines in the figures) which receives a multi-layer cushion area. This multi-layer cushion area comprises three layers, of which the two upper layers extend essentially over the entire footbed and run out at the edges of the footbed, while the lower layer is limited to the midfoot area. The cover layer 4 extends over the cushion area, so that there is a uniform finish on the top of the footbed. The lower layer 7 abuts the rigid sole 8 on the underside.

Mit einem derartigen Polsterbereich 3 mit Dreischichtaufbau läßt sich die Druck- und/oder Scherbelastung des Fußes in diesem Bereich, insbesondere bei tiefstehendem Knochen etc., beträchtlich herabsetzen. Es wird eine ausreichende Polsterung des Fußes gewährleistet, wobei die obere Schicht 5 für die Ausbildung des individuellen Fußbettes sorgt, während die mittlere Schicht 6 der Polsterung eine entsprechende Stabilität verleiht. Die untere Schicht 7 dient als Pufferschicht, um das Eindrücken der mittleren Schicht 6 bei tiefstehendem Knochen etc. zu ermöglichen.With such a cushion area 3 with a three-layer structure, the pressure and / or shear stress of the foot can be considerably reduced in this area, particularly in the case of deep-set bones, etc. Sufficient cushioning of the foot is ensured, the upper layer 5 providing the formation of the individual footbed, while the middle layer 6 gives the cushioning a corresponding stability. The lower layer 7 serves as a buffer layer in order to enable the middle layer 6 to be pressed in when the bone is deep, etc.

Die obere Schicht 5 besitzt eine durchschnittliche Dicke von 2 mm und besteht aus einem offenporigen Zellkautschuk NR , der die folgenden Materialeigenschaften besitzt:
   Rohstoffbasis: SBR + NR
   ASTM Grad: Re 42 - 43
   Stauchhärte: 35 - 91 kPa
   Druckverformungstest: 50 - 60 %
   Rohdichte: 180 - 280 kg/m³.The upper layer 5 has an average thickness of 2 mm and consists of an open-celled cellular rubber NR, which has the following material properties:
Raw material base: SBR + NR
ASTM grade: Re 42-43
Compression hardness: 35 - 91 kPa
Compression set test: 50 - 60%
Bulk density: 180 - 280 kg / m³.

Es handelt sich hierbei um ein relativ weiches Material mit geringem Rückstellvermögen.It is a relatively soft material with little resilience.

Die mittlere Schicht 6 besteht aus einem geschlossenporigen Zellkautschuk und weist eine Dicke von etwa 3 mm auf. Die Dichte des Materiales beträgt 0,07 g/cm³ und die Härte/Shore A 18°. Das Material ist relativ hart und fest und weist ein hohes Rückstellvermögen auf.The middle layer 6 consists of a closed-cell cellular rubber and has a thickness of approximately 3 mm. The density of the material is 0.07 g / cm³ and the hardness / Shore A 18 °. The material is relatively hard and strong and has a high resilience.

Die untere Schicht 7 besteht auf einem offenporigen Zellkautschuk NRB und weist eine durchschnittliche Dicke von etwa 6 mm auf. Das Material ist relativ fest und hart und besitzt folgende Eigenschaften:
   Rohstoffbasis: SBR + NR
   ASTM Grad: RE 43
   Stauchhärte: 63 - 91 kPa
   Druckverformungstest: 45 - 55 %
   Rohdichte: 160 - 240 kg/m³.The lower layer 7 consists of an open-pore cellular rubber NRB and has an average thickness of approximately 6 mm. The material is relatively strong and hard and has the following properties:
Raw material base: SBR + NR
ASTM grade: RE 43
Compression hardness: 63 - 91 kPa
Compression set test: 45 - 55%
Bulk density: 160 - 240 kg / m³.

Das Material der unteren Schicht 7 besitzt ein Rückstellvermögen, das größer ist als das der oberen Schicht, jedoch kleiner als das der mittleren Schicht. Sämtliche Schichten sind in geeigneter Weise miteinander und im Fußbett verklebt.The material of the lower layer 7 has a resilience that is greater than that of the upper layer, but smaller than that of the middle layer. All layers are glued together in a suitable manner and in the footbed.

Die Starrsohle 8 kann beispielsweise aus Hartpapier (Pertinax) bestehen. Es handelt sich hierbei um ein dünnes Material mit einer hohen Festigkeit und geringem Gewicht. Die Dicke beträgt etwa 3 mm. Eine solche Starrsohle verteilt die Druckbelastung gleichmäßig.The rigid sole 8 can be made of hard paper (Pertinax), for example. It is a thin material with high strength and low weight. The thickness is about 3 mm. Such Rigid sole distributes the pressure load evenly.

Figur 3 zeigt einen Schnitt durch das Schaftmaterial für den Schuh. Auch das Schaftmaterial ist entsprechend gepolstert, um Druckbeanspruchungen des Fußes zu vermeiden. Es besteht von außen nach innen aus einer Nappalederschicht 10, einem Verstärkungsband 11, einer Polsterschicht 12 aus geschlossenporigem Zellkautschuk mit einer Stärke von etwa 3 mm und einer Schicht 13 aus vegetabil gegerbtem Futterleder.Figure 3 shows a section through the shaft material for the shoe. The upper material is also padded to avoid pressure on the foot. From the outside in, it consists of a nappa leather layer 10, a reinforcement band 11, a cushion layer 12 of closed-cell cellular rubber with a thickness of approximately 3 mm and a layer 13 of vegetable-tanned lining leather.

Es wurden zu Vergleichszwecken auch vier- und fünfschichtige Polsterungen ausprobiert. Dabei fanden verschiedene Polstergrade und -anordnungen Verwendung, die aber keinen Mehreffekt gegenüber der dreischichtigen Polsterung erbrachten. Es können somit weitere Polsterschichten zum Aufbau benützt werden, jedoch ist die dreischichtige Polsterung vollkommend ausreichend.Four- and five-layer upholstery was also tried out for comparison purposes. Different degrees and arrangements of upholstery were used, but did not produce any additional effects compared to the three-layer upholstery. Additional layers of upholstery can therefore be used for the construction, but the three-layer upholstery is completely sufficient.

Figur 4 zeigt eine Teildraufsicht und einen Querschnitt durch den Fersenbereich des Schuhs. Wie man der Figur entnehmen kann, besitzt das Fußbett eine Längsgewölbestütze 14, die in eine bei 15 angedeutete Fersenschrägstellung übergeht. Es erfolgt hierbei ein flächiger Übergang, so daß punktuelle Belastungen vermieden werden. Der Schnitt durch den Fersenbereich zeigt, daß sich die Fersenschrägstellung 15 etwa über die Hälfte des Fersenbereiches in Längsrichtung gesehen erstreckt und dabei von der Mitte des Fersenbereiches bis zum Innenrand desselben ansteigt. So geht die Fersenschrägstellung 15 allmählich in die Schalenkante des Fußbettes über.Figure 4 shows a partial plan view and a cross section through the heel area of the shoe. As can be seen from the figure, the footbed has a longitudinal arch support 14 which merges into an inclined heel position indicated at 15. There is a flat transition, so that selective loads are avoided. The section through the heel area shows that the oblique heel position 15 extends approximately over half of the heel area in the longitudinal direction and rises from the center of the heel area to the inner edge thereof. So the heel inclination 15 gradually merges into the shell edge of the footbed.
