Abstract

The shoe, has a shoe upper part and a sole. The sole has a supporting part, which is designed for receiving the heel region of the wearer's foot and is connected to the shoe upper part, and a sole element, which is connected to the supporting part. In order to improve the damping behavior of the shoe, the supporting part and the sole element are spaced apart from each other, in the longitudinal direction of the shoe. The connection between the supporting part and the sole element is preformed at two spaced-apart points in such a way as to form, under the heel region of the wearer's foot, a gap. The gap extends at least in portions over the entire width of the sole. The sole element, in the rear end region of the shoe, is connected to the supporting part.

Description

Schuh, insbesondere Sportschuh Shoe, in particular sports shoe
Die Erfindung betrifft einen Schuh, insbesondere einen Sportschuh, mit einem Schuhoberteil und einer Sohle, wobei die Sohle ein zur Aufnahme des Fersenbereichs des Fußes des Trägers ausgebildetes und mit dem Schuhoberteil fest verbundenes Träger- oder Innenteil und ein mit dem Träger- oder Innenteil verbundenes Sohlenelement aufweist.The invention relates to a shoe, in particular a sports shoe, with a shoe upper and a sole, the sole being a trained for receiving the heel portion of the foot of the wearer and firmly connected to the shoe upper carrier or inner part and connected to the carrier or inner sole member having.
Bei Schuhen dieser Art ist es im allgemeinen erforderlich, für ein gewünschtes Feder- und DämpfVerhalten der Sohle zu sorgen. Hierzu sind im Stand der Technik vielfältige Lösungen bekannt.In shoes of this type, it is generally necessary to provide a desired spring and damping behavior of the sole. For this purpose, various solutions are known in the prior art.
In der WO 01/17384 A2 ist eine Sohle für einen Schuh beschrieben, bei der im Hinterfußbereich zwischen einem Träger- bzw. Innenteil und einer Außensohle eine Anzahl Rippen positioniert sind, die eine gekrümmte Form aufweisen. Damit wird erreicht, dass bei Belastung der Sohle mit Auftrittskräften ein Biegen der Rippen erfolgt, wobei die Rippe eine fast halbellipsoide Form einnimmt.WO 01/17384 A2 describes a sole for a shoe in which a number of ribs, which have a curved shape, are positioned in the region of the back of the foot between a carrier or inner part and an outer sole. It is thus achieved that, when the sole is loaded with impact forces, the ribs are bent, with the rib taking on an almost semiellipsoidal shape.
Bekannt ist es ferner, relativ aufwändige Dämpfungselemente einzusetzen, die dann in der Lage sind, dem Schuh ein definiertes Federungs- und Dämpfungsverhalten zu verleihen. Als Beispiel hierfür sei die Lösung gemäß der WO 03/092423 Al genannt, aus der ein Dämpfungselement für einen Sportschuh bekannt ist, das einen speziellen Aufbau aufweist. Das Dämpfungselement hat eine Vielzahl von nebeneinander angeordneten Einzelelementen, die jeweils eine Feder- und Dämpfkammer nach Art eines Kolben-Zylinder- Systems bilden. In der Form entsprechende erste und zweite Elemente sind über einen Verbindungsabschnitt miteinander verbunden, wobei bei Belastung der Sohle das kleiner ausgebildete Element in das größere eintritt, das hierfür einen Aufnahmeraum bildet.It is also known to use relatively complex damping elements, which are then able to give the shoe a defined suspension and damping behavior. An example of this is the solution according to WO Named 03/092423 Al, from which a damping element for a sports shoe is known, which has a special structure. The damping element has a plurality of juxtaposed individual elements, each forming a spring and damping chamber in the manner of a piston-cylinder system. In the form corresponding first and second elements are connected to each other via a connecting portion, wherein upon loading of the sole, the smaller formed element enters the larger, which forms a receiving space for this purpose.
Ein derartiges Dämpfelement ist gemäß der genannten Lösung primär dafür vorgesehen, in eine Zwischensohle integriert zu werden, wozu es im Stand der Technik weitere Vorbilder gibt. Hierzu wird auf die EP 0 387 505 Al hingewiesen, die ein wabenförmig ausgebildetes Dämpfungselement offenbart, das in einen Aufhahmeraum in der Zwischensohle des Schuhs eingesetzt wird.Such a damping element is according to said solution primarily intended to be integrated into a midsole, for which there are other models in the prior art. Reference is made to EP 0 387 505 A1, which discloses a honeycomb-shaped damping element which is inserted into a receiving space in the midsole of the shoe.
Nachteilig ist es bei den vorbekannten Lösungen, dass die Herstellung derart hochwertiger Schuhe einen nicht unerheblichen Kostenaufwand verursacht. Es ist daher erstrebenswert, ein hinreichendes Federungs- und Dämpfungsverhalten im Schuh sicherzustellen, ohne hierfür die hohen Kosten für Herstellung und/oder Montage in Kauf nehmen zu müssen.It is disadvantageous in the previously known solutions that the production of such high-quality shoes causes a not inconsiderable expense. It is therefore desirable to ensure a sufficient suspension and damping behavior in the shoe, without having to accept the high costs of production and / or assembly in purchasing.
Der Erfindung liegt die A u f g a b e zugrunde, einen Schuh, insbesondere einen Sportschuh, der eingangs genannten Art so fortzubilden, dass ein gut steuerbarer Verlauf der Federsteifigkeit bzw. des Dämpfungsverhaltens erzielt werden kann, wobei jedoch eine ökonomische Fertigung des Schuhs sichergestellt sein soll. Ferner soll eine definierte Federsteifigkeit über dem Federweg erhalten bleiben; es soll insbesondere möglich sein, das Federverhalten der Schuhsohle beeinflussen zu können. Die L ö s u n g dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass das Träger- oder Innenteil und das Sohlenelement des Schuhs zumindest über einen Teil ihrer Erstreckung in Schuhlängsrichtung betrachtet voneinander beabstandet sind, wobei die Verbindung zwischen dem Trägeroder Innenteil und dem Sohlenelement an zwei voneinander beabstandeten Stellen so erfolgt, dass sich unter dem Fersenbereich des Fußes des Trägers ein Spalt, insbesondere ein Luftspalt, zwischen dem Träger- oder Innenteil und dem Sohlenelement ergibt, wobei sich der Spalt zumindest abschnittsweise über die gesamte Breite der Sohle erstreckt und wobei das Sohlenelement im hinteren Endbereich des Schuhs mit dem Träger- oder Innenteil verbunden ist.The invention is based on the object, a shoe, in particular a sports shoe, of the type mentioned in such a way that a well controllable course of the spring stiffness or the damping behavior can be achieved, but an economical production of the shoe should be ensured. Furthermore, a defined spring stiffness over the travel should be maintained; It should be possible in particular to be able to influence the spring behavior of the shoe sole. The solution to this problem by the invention is characterized in that the support or inner part and the sole element of the shoe are at least over a part of their extension viewed in the shoe longitudinal direction spaced from each other, wherein the connection between the carrier or inner part and the sole element at two from each other spaced locations so that there is a gap, in particular an air gap, between the carrier or inner part and the sole element below the heel area of the foot of the wearer, wherein the gap extends at least in sections over the entire width of the sole and wherein the sole element in rear end portion of the shoe is connected to the carrier or inner part.
Das Sohlenelement erstreckt sich dabei bevorzugt im hinteren Endbereich des Schuhs - von der Seite des Schuhs aus betrachtet - bogen- oder schalenförmig um das Träger- oder Innenteil herum, wobei zwischen demThe sole element preferably extends in the rear end region of the shoe - viewed from the side of the shoe - arcuate or cup-shaped around the carrier or inner part around, wherein between the
Träger- oder Innenteil und dem Sohlenelement zumindest abschnittsweise derCarrier or inner part and the sole element at least partially the
Spalt verbleibt. Dabei kann das Sohlenelement am Träger- oder Innenteil in einer gewissen Höhe über dem Boden angebunden sein. Insofern stellt bei dieser Ausfuhrungsform das Sohlenelement eine geschlossene Form desGap remains. In this case, the sole element can be connected to the carrier or inner part at a certain height above the ground. In this respect, in this embodiment, the sole element forms a closed shape of the

Bevorzugt ist der Spalt zwischen dem Träger- oder Innenteil und dem Sohlenelement in Schuhlängsrichtung betrachtet zwischen dem tiefsten Punkt der Ferse bzw. des Träger- oder Innenteils und dem hinteren Ende des Trägeroder Innenteils angeordnet, wobei besonders bevorzugt vorgesehen ist, dass sich der Spalt mindestens über den Bereich zwischen dem tiefsten Punkt der Ferse bzw. des Träger- oder Innenteils und dem in Schuhlängsrichtung betrachtet hinteren Ende des Träger- oder Innenteils erstreckt. Dabei kann insbesondere vorgesehen sein, dass sich der Spalt zwischen dem Träger- oder Innenteil und dem Sohlenelement in Schuhlängsrichtung betrachtet über mindestens 10 %, bevorzugt über mindestens 15 %, der gesamten Länge des Schuhs erstreckt.Preferably, the gap between the carrier or inner part and the sole element viewed in the shoe longitudinal direction between the lowest point of the heel or of the carrier or inner part and the rear end of the carrier or inner part is arranged, wherein particularly preferably provided that the gap at least over extends the region between the lowest point of the heel or of the carrier or inner part and the rear end of the carrier or inner part viewed in the shoe longitudinal direction. It can In particular, it may be provided that the gap between the carrier or inner part and the sole element in the longitudinal direction of the shoe extends over at least 10%, preferably over at least 15%, of the entire length of the shoe.
Mit dieser Ausgestaltung wird ein "schwebender Sohlenbereich" geschaffen, d. h. ein - in Längsrichtung des Schuhs betrachtet - mit spaltförmigem Abstand versehener materialfreier (nur mit Luft gefüllter) Bereich, in dem das Träger- oder Innenteil vom Sohlenelement beabstandet ist, wodurch ein federndes Verhalten der Sohle erreicht wird.With this embodiment, a "floating sole area" is created, d. H. a - viewed in the longitudinal direction of the shoe - with a gap-like distance provided material-free (only filled with air) area in which the carrier or inner part is spaced from the sole element, whereby a resilient behavior of the sole is achieved.
Der Spalt zwischen dem Träger- oder Innenteil und dem Sohlenelement kann von der Seite des Schuhs aus betrachtet bogenförmig, insbesondere kreisbogenförmig oder sichelförmig, ausgebildet sein. Dabei kann die im hinteren Endbereich des Schuhs angeordnete Verbindungsstelle zwischen dem Träger- oder Innenteil und dem Sohlenelement in einer Höhe über der Bodenfläche liegen, die mindestens 20 %, meist mindestens 40 % und bevorzugt mindestens 60 %, der Höhe des Schuhs im Fersenbereich entspricht.The gap between the carrier or inner part and the sole element can, viewed from the side of the shoe, be arcuate, in particular arcuate or sickle-shaped. In this case, arranged in the rear end region of the shoe connection point between the support or inner part and the sole element at a height above the floor surface, which corresponds to at least 20%, usually at least 40% and preferably at least 60%, the height of the shoe in the heel area.
Das Pronations- bzw. Supinationsverhalten des Schuhs kann gezielt beeinflusst werden, wenn weiterbildungsgemäß ein Stützelement im Spalt zwischen dem Träger- oder Innenteil und dem Sohlenelement angeordnet ist. Dieses Stützelement ist in jedem Falle so angeordnet, dass über einen definierten Bereich - in Richtung der Längsachse des Schuhs betrachtet - der in Rede stehende Spalt verbleibt.The pronation or supination behavior of the shoe can be influenced in a targeted manner if, according to further development, a support element is arranged in the gap between the carrier or inner part and the sole element. This support element is arranged in each case so that over a defined area - viewed in the direction of the longitudinal axis of the shoe - the gap in question remains.
Bevorzugt ist daher vorgesehen, dass sich das Stützelement ab dem tiefsten Punkt der Ferse bzw. des Träger- oder Innenteils in Schuhlängsrichtung in Richtung des vorderen Endes des Träger- oder Innenteils erstreckt und insbesondere den Rest des Spalts frei lässt.Preferably, it is therefore provided that the support element from the lowest point of the heel or of the carrier or inner part in the shoe longitudinal direction in Direction of the front end of the support or inner part extends and in particular leaves free the rest of the gap.
Weiterhin kann sich das Stützelement nur über einen Teil der Breite des Träger- oder Innenteils erstrecken. Das Stützelement kann sich dabei in Schuhlängsrichtung in Richtung des vorderen Endes des Träger- oder Innenteils verbreitern. Durch asymmetrische Verbreiterung des Stützelements zu den Schuhseiten hin kann das Pronations- bzw. Supinationsverhalten gezielt beeinflusst werden.Furthermore, the support member may extend only over part of the width of the carrier or inner part. The support element can widen in the shoe longitudinal direction in the direction of the front end of the carrier or inner part. As a result of asymmetric widening of the support element towards the sides of the shoe, the pronation or supination behavior can be influenced in a targeted manner.
Das Träger- oder Innenteil ist bevorzugt als schalenförmiger Körper ausgebildet bzw. es weist einen schalenförmigen Körper auf, der die Ferse des Trägers des Schuhs zumindest teilweise umgibt.The support or inner part is preferably formed as a shell-shaped body or it has a cup-shaped body which surrounds the heel of the wearer of the shoe at least partially.
Das Sohlenelement wird bevorzugt zumindest teilweise aus einem Anbindungsteil und einer Außensohle gebildet, wobei das Anbindungsteil mit seiner einen Seite mit der Außensohle verbunden ist. Dabei kann insbesondere vorgesehen sein, dass sich die Außensohle über den gesamten Bereich erstreckt, in dem das Träger- oder Innenteil und das Sohlenelement voneinander beabstandet sind.The sole element is preferably formed at least partially from a connecting part and an outsole, wherein the connecting part is connected with its one side with the outsole. It can be provided in particular that the outsole extends over the entire area in which the carrier or inner part and the sole element are spaced from each other.
Die Teile der Sohle bestehen bevorzugt aus Kunststoff, insbesondere aus thermoplastischem Material. Dabei ist namentlich bevorzugt an Polyäthylen, Polypropylen, Polybutan, Polyamid, Polyurethan oder eine Mischung von wenigstens zwei dieser Kunststoffe gedacht. Der Kunststoff kann durchscheinend oder durchsichtig sein. Auch die Außensohle kann aus Kunststoff, vorzugsweise aus Polyäthylen, Polypropylen, Polybutan, Polyamid, Polyurethan oder einer Mischung von wenigstens zwei dieser Kunststoffe, oder aus Gummi bestehen, wobei das Material nicht durchscheinend oder nicht durchsichtig ist.The parts of the sole are preferably made of plastic, in particular of thermoplastic material. In particular, preference is given to polyethylene, polypropylene, polybutane, polyamide, polyurethane or a mixture of at least two of these plastics. The plastic can be translucent or transparent. The outsole may also be made of plastic, preferably of polyethylene, polypropylene, polybutane, polyamide, polyurethane or a mixture of at least two of these Plastics, or rubber, wherein the material is not translucent or not transparent.
Der Werkstoff der einzelnen Sohlenbestandteile sowie deren geometrische Abmessungen können zur Festlegung der Feder- und/oder Dämpfungseigenschaften der Sohle fachmännisch ausgewählt werden.The material of the individual sole components as well as their geometric dimensions can be expertly selected to determine the spring and / or damping properties of the sole.
Mit der vorgeschlagenen Ausgestaltung wird in einfacher Weise erreicht, dass sich - zumindest über einen gewissen Federwegbereich - ein gewünschter Verlauf der Federsteifigkeit des Schuhs und insbesondere dessen Sohle bei Belastung ergibt.With the proposed embodiment is achieved in a simple manner that - at least over a certain Federwegbereich - results in a desired course of the spring stiffness of the shoe and in particular its sole under load.
Die Fertigung des vorgeschlagenen Schuhs ist in einfacher Weise und kostengünstig möglich, wofür bekannte Methoden eingesetzt werden.The production of the proposed shoe is possible in a simple manner and inexpensively, for which known methods are used.

Fig. 6 den Schnitt C-D gemäß Fig. 5 für den Schuh gemäß Fig. 2.6 shows the section C-D according to FIG. 5 for the shoe according to FIG. 2.
In Fig. 1 ist ein Sportschuh von der Seite aus betrachtet dargestellt, der in bekannter Weise ein Schuhoberteil 1 aufweist, das mit einer Sohle 2 verbunden ist. Die Sohle 2 weist ein Träger- oder Innenteil 3 auf, das jedenfalls im hinteren Bereich des Schuhs als Fersenschale ausgebildet ist und zur teilweisen Umgebung der Ferse des Fußes des Trägers geformt ist. Der Kontakt mit dem Boden erfolgt über ein Sohlenelement 4, das jedenfalls im hinteren Bereich des Schuhs aus einem Anbindungsteil 12 besteht, an dessen Unterseite eine Außensohle 13 befestigt, z. B. angeklebt, ist.In Fig. 1, a sports shoe viewed from the side is shown, which has in a known manner a shoe upper 1, which is connected to a sole 2. The sole 2 has a carrier or inner part 3, which is in any case formed in the rear region of the shoe as a heel cup and is formed to the partial environment of the heel of the foot of the wearer. The contact with the ground via a sole element 4, which at least in the rear region of the shoe consists of a connection part 12, attached to the underside of an outsole 13, z. B. glued, is.
Wesentlich ist, dass zwischen dem Träger- oder Innenteil 3 und dem Sohlenelement 4 ein materialfreier (luftgefüllter) Spalt 7 verbleibt, der sich zumindest abschnittsweise über die gesamte Breite des Schuhs bzw. der SohleIt is essential that between the carrier or inner part 3 and the sole element 4, a material-free (air-filled) gap 7 remains, at least in sections over the entire width of the shoe or the sole
2 erstreckt. Dieser Spalt 7 wird geschaffen, indem das Träger- oder Innenteil2 extends. This gap 7 is created by the carrier or inner part
3 mit dem Sohlenelement 4 an zwei Verbindungsstelle 5 und 6 miteinander verbunden ist, so dass sich zwischen diesen beiden Stellen 5, 6 ein freitragender Bereich ergibt; dieser Bereich kann als "schwebender Fersenbereich" angesprochen werden.3 is connected to the sole element 4 at two connection points 5 and 6, so that a self-supporting area results between these two points 5, 6; this area can be addressed as a "hovering heel area".
Wie in Fig. 1 zu sehen ist, verläuft der Spalt 7 und damit der freitragende Bereich über eine Erstreckung x, der in Schuhlängsrichtung L gemessen wird. Im Verhältnis zur gesamten Länge X des Schuhs ist festzustellen, dass die Erstreckung x mindestens 10 % dieses Wertes beträgt, so dass sich der freitragende Bereich als sehr viel größer erweist, als es bei einer Sohle mit Wabenelementen der Fall wäre, deren Achse sich quer zur Längsrichtung L und horizontal erstreckt. Im Ausführungsbeispiel nach Fig. 1 beträgt die Erstreckung x etwa 30 % der Gesamtlänge X.As can be seen in FIG. 1, the gap 7, and thus the cantilevered region, extends over an extension x, which is measured in the longitudinal direction L of the shoe. In relation to the total length X of the shoe, it should be noted that the extension x is at least 10% of this value, so that the cantilevered area proves to be much larger than would be the case for a honeycomb sole whose axis is transverse to the Longitudinal direction L and extends horizontally. In the embodiment of FIG. 1, the extension x is about 30% of the total length X.
Um den gewünschten Federeffekt des freitragenden Bereichs zu erzielen, sollte sich der Spalt 7 - in Schuhlängsrichtung L betrachtet - zwischen dem tiefsten Punkt 8 und dem hinteren Ende 9 des Träger- oder Innenteils 3 erstrecken. Im Ausführungsbeispiel gemäß Fig. 1 ist der Spalt 7 indes deutlich länger.In order to achieve the desired spring effect of the cantilevered area, the gap 7 - viewed in the shoe longitudinal direction L - should extend between the lowest point 8 and the rear end 9 of the support or inner part 3. In the embodiment of FIG. 1, however, the gap 7 is significantly longer.
Zu erkennen ist weiterhin, dass der Spalt 7 - von der Schuhseite aus betrachtet - einen sichelförmigen bzw. kreisbogenförmigen Verlauf hat und im hinteren Bereich des Schuhs, d. h. an der Verbindungsstelle 6, in einer Höhe h endet, die deutlich über dem Bodenbereich liegt. Im Ausführungsbeispiel ist vorgesehen, dass die Höhe h der hinteren Verbindungsstelle 6 etwa 65 % der gesamten Höhe H des Schuhs im Fersenbereich entspricht. Bevorzugt liegt die Verbindungsstelle 6 bei mindestens 40 % der Höhe H.It can also be seen that the gap 7 - viewed from the shoe side - has a crescent-shaped or circular arc-shaped course and in the rear region of the shoe, d. H. at the junction 6, ends at a height h which is well above the floor area. In the exemplary embodiment, it is provided that the height h of the rear connection point 6 corresponds to approximately 65% of the total height H of the shoe in the heel region. Preferably, the joint 6 is at least 40% of the height H.
Zwischen dem tiefsten Punkt 8 und dem hinteren Ende 9 des Träger- oder Innenteils 3 verläuft der Spalt 7 im wesentlichen kreisbogenformig, wobei sich der Kreisbogen über mindestens 45°, vorzugsweise über mindestens 60°, erstreckt. Im Ausführungsbeispiel gemäß Fig. 1 beträgt die Erstreckung des Kreisbogens ca. 90°.Between the lowest point 8 and the rear end 9 of the carrier or inner part 3 of the gap 7 extends substantially kreisbogenformig, wherein the arc extends over at least 45 °, preferably over at least 60 °. In the embodiment of FIG. 1, the extension of the circular arc is about 90 °.
Das in Fig. 2 dargestellte Ausführungsbeispiel des Sportschuhs unterscheidet sich von demjenigen gemäß Fig. 1, dass zusätzlich ein Stützelement 10 vorgesehen ist, das als Fersenkeil fungiert und das Träger- oder Innenteil 3 gegenüber dem Sohlenelement 4 teilweise abstützt. Im Ausführungsbeispiel erstreckt sich das Stützelement vom tiefsten Punkt 8 des Träger- oder Innenteils 3 in Richtung des vorderen Endes 11 des Träger- oder Innenteils 3. Wie zu sehen ist, verringert sich die Erstreckung x des Spalts 7 im Vergleich zur Lösung gemäß Fig. 1, beträgt jedoch nach wie vor mindestens 10 % der Gesamtlänge X des Schuhs.The exemplary embodiment of the sports shoe illustrated in FIG. 2 differs from that according to FIG. 1 in that a support element 10 is additionally provided which acts as a heel wedge and partially supports the carrier or inner part 3 with respect to the sole element 4. In the exemplary embodiment, the support element extends from the lowest point 8 of the carrier or inner part 3 in the direction of the front end 11 of the carrier or inner part. 3 As can be seen, the extension x of the gap 7 is reduced in comparison to the solution according to FIG. 1, but is still at least 10% of the total length X of the shoe.
Wie anhand der Schnittdarstellung gemäß Fig. 3 gesehen werden kann (Schnitt A-B gemäß Fig. 2), erstreckt sich das Stützelement 10 nicht über die gesamte Schuhbreite, sondern nur über einen Teil der Breite; links und rechts vom Stützelement 10 - in Schuhlängsrichtung L betrachtet - verbleibt ein seitlich angeordneter Spalt 7 auch entlang der Längserstreckung des Stützelements 10. Durch entsprechende Ausformung des Stützelements 10 und namentlich durch den Verlauf dessen Breite über die Schuhlängsrichtung L kann das Pronations- und Supinationsverhalten des Schuhs beeinflusst und an gewünschte Verhältnisse angepasst werden.As can be seen from the sectional view according to FIG. 3 (section A-B according to FIG. 2), the support element 10 does not extend over the entire shoe width, but only over a part of the width; Left and right of the support member 10 - viewed in the shoe longitudinal direction L - remains a laterally disposed gap 7 along the longitudinal extent of the support member 10. By appropriate shaping of the support member 10 and especially by the course of its width on the shoe longitudinal direction L, the pronation and supination behavior of Shoe influenced and adapted to desired conditions.
Aus der Darstellung gemäß Fig. 4 ist zu erkennen, wie sich die Außensohle 13 im Fersenbereich des Schuhs, an der Außenseite des Anbindungsteils 12 angebracht, nach oben erstreckt. Die Außensohle 13 ist dabei mit einer gewünschten Profilierung versehen, wie es sich aus Fig. 4 ergibt.It can be seen from the illustration according to FIG. 4 how the outsole 13 in the heel region of the shoe, attached to the outside of the connection part 12, extends upwards. The outsole 13 is provided with a desired profiling, as is apparent from Fig. 4.
Ein Beispiel für die Profilierung der Außensohle 13 ergibt sich auch aus der Darstellung gemäß Fig. 5.An example of the profiling of the outsole 13 also results from the illustration according to FIG. 5.
In Fig. 6 ist der Schnitt C-D gemäß Fig. 5 zu sehen, aus dem hervorgeht, dass das Sohlenelement 4 im Vorderbereich des Schuhs ein Außensohlenelement 14 aufweisen kann. BezugszeichenlisteFIG. 6 shows the section CD according to FIG. 5, from which it can be seen that the sole element 4 can have an outsole element 14 in the front region of the shoe.
