Abstract

1. A method for the orthopedic adaptation of shoes wherein, in a shoe with a sole damaged inside by a dent and the like formed through faulty posture of the foot during use of the shoe, first one removes the old outsole, at least for the most part, and subsequently applies a new outsole as well as an intermediate sole provided with a cut-out for cushioning in the region of the dent or the like. e. g. a butterfly-like roll, and cushioning between the insole and outsole, characterized in that first a sandwich blank is prefabricated by the new outsole (2) being connected to the intermediate sole (3) and cushioning (4) projecting above the intermediate sole being inserted into the cut-out (5) of the latter and that, in the case of a shoe being applied, the sandwich blank is adjusted to the respective shoe at least with respect to its outline and is subsequently connected to the insole (9) and/or remaining layer of outsole and/or to an infolded welt of upper leather (14) of the shoe (11), the deformation of the dent being at least partly reversed by the projecting cushioning.

Description

Die Erfindung betrifft ein Verfahren zur orthopädischen Schuhzurichtung, wobei bei einem Schuh mit einer durch Fußfehlstellung während der Benutzung des Schuhes gebildeten, innenseitig durch eine Eindellung und dgl. beschädigten Sohle, zunächst die alte Laufsohle zumindest größtenteils entfernt wird und wobei anschließend eine neue Laufsohle sowie eine mit einem Ausschnitt für eine Weichbettung im Bereich der Eindellung oder dgl. versehene Zwischensohle, z. B. eine Schmetterlingsrolle und eine zwischen der Brandsohle und der Laufsohle befindliche Weichbettung angebracht werden.The invention relates to a method for orthopedic shoe dressing, in which, in the case of a shoe with a sole which is formed by misalignment during use of the shoe and is damaged on the inside by a dent and the like, the old outsole is at least largely removed and then a new outsole and a provided with a cutout for soft bedding in the area of the indentation or the like. Midsole, z. B. a butterfly roller and a soft bed located between the insole and the outsole.

Zur Behandlung von Fußschäden ist es bereits bekannt, einen normalen Straßenschuh durch eine orthopädische Schuhzurichtung zu korrigieren. Bei dem zu bearbeitenden Schuh wird dabei zunächst die Laufsohle entfernt oder bis auf eine dünne Schicht abgeschliffen und anschließend wird, je nach Fußschaden, eine durch ein Materialzwischenstück gebildete Zwischensohle aufgeklebt, die im Bereich einer Fuß-Druckstelle eine entsprechende Aussparung aufweist. Die Zwischensohle bildet später eine sogenannte Rolle, die je nach Form und Lage des Zwischensohlen-Ausschnittes beispielsweise als Schmetterlingsrolle, Winkelrolle, Ballenrolle usw. bezeichnet wird. In die Aussparung der auf die Laufsohlenrestschicht od. dgl. aufgeklebten Zwischensohle wird dann ein die Weichbettung bildendes Druckpolster aus weichelastischem Material eingesetzt. Nach dem Überschleifen der Unterseite der Zwischensohle mit Weichbettung und gegebenenfalls Formung einer Abrundung im Spitzenbereich, wird dann die neue Laufsohle aufgebracht. In der Praxis hat es sich herausgestellt, daß das Druckpolster bereits nach vergleichsweise kurzer Zeit zusammengedrückt wird und dann keine elastisch abstützende Polsterwirkung mehr hat.For the treatment of foot damage, it is already known to correct a normal street shoe by means of an orthopedic shoe preparation. In the case of the shoe to be processed, the outsole is first removed or ground down to a thin layer and then, depending on the foot damage, an intermediate sole formed by a material intermediate piece is glued on, which has a corresponding recess in the area of a foot pressure point. The midsole later forms a so-called roll, which depending on the shape and position of the midsole cutout is referred to as a butterfly roll, angled roll, ball roll, etc. A pressure cushion, which forms the soft bed and is made of soft elastic material, is then inserted into the recess in the midsole glued onto the outer sole layer or the like. After smoothing the underside of the midsole with soft bedding and, if necessary, forming a rounding in the toe area, the new outsole is then applied. In practice, it has been found that the pressure cushion is compressed after a comparatively short time and then no longer has an elastically supporting cushion effect.

Außerdem spürt der Benutzer dann den Umgrenzungsrand des Ausschnittes, so daß die Benutzung des Schuhes unangenehm wird. Weiterhin ist nachteilig, daß auch nach der Schuhzurichtung eine in der Schuh-Brandsohle vorhandene Eindellung im Bereich der Fußdruckstellung zumindest weitgehend erhalten bleibt. Schließlich ist bei dieser Schuhzurichtung weiterhin nachteilig, daß sämtliche Einzelteile der Schuhsohle für jeden Schuh einzeln zugeschnitten und miteinander verklebt werden müssen.In addition, the user then feels the boundary edge of the cutout, so that the use of the shoe becomes uncomfortable. A further disadvantage is that even after the shoe has been finished, a dent in the shoe insole in the area of the foot pressure position is at least largely retained. Finally, it is a disadvantage of this shoe preparation that all individual parts of the shoe sole have to be cut individually for each shoe and glued together.

Aufgabe der vorliegenden Erfindung ist es, ein Verfahren und eine danach hergestellte Schuhsohle bei einer orthopädischen Schuhzurichtung zu schaffen, bei der einerseits die Schuhzurichtung vereinfacht ist und wobei die wirksame Benutzungszeit des zugerichteten Schuhs verlängert ist.The object of the present invention is to provide a method and a shoe sole produced thereafter for an orthopedic shoe dressing, in which the shoe dressing is simplified on the one hand and the effective usage time of the prepared shoe is extended.

Zur Lösung dieser Aufgabe wird erfindungsgemäß insbesondere vorgeschlagen, daß zunächst ein Sandwich-Rohling vorgefertigt wird, indem die neue Laufsohle mit der Zwischensohle verbunden und in den Zwischensohlen-Ausschnitt eine über die Zwischensohle überstehende Weichbettung eingesetzt wird und daß im Falle einer Schuhzurichtung der Sandwich-Rohling \zumindest bezüglich seines Umrisses an den jeweiligen Schuh angepaßt und anschließend mit der Brandsohle und/oder einer Laufsohlenrestschicht und/oder einem Oberlederzwickeinschlag des Schuhes verbunden wird, wobei die Eindellung durch die überstehende Weichbettung zumindest teilweise zurückverformt wird. Durch die Vorfertigung eines Sandwich-Rohlings ist eine wesentlich wirtschaftlichere, orthopädische Schuhzurichtung möglich.To solve this problem, the invention proposes, in particular, that a sandwich blank is first prefabricated by connecting the new outsole to the midsole and inserting a soft bed protruding from the midsole in the midsole cutout and that in the case of shoe finishing the sandwich blank \ at least adapted to the respective shoe with regard to its outline and then connected to the insole and / or an outer sole layer and / or a leather uppers of the shoe, the indentation being at least partially deformed by the protruding soft bedding. By prefabricating a sandwich blank, a much more economical, orthopedic shoe preparation is possible.

Die Erfindung betrifft auch eine Schuhsohle zur orthopädischen Schuhzurichtung für Schuhe, die während der Benutzung durch eine Fußfehlstellung und dgl. beschädigt wurden, insbesondere in Form einer innenseitigen Sohleneindellung, wobei die Schuhsohle eine Laufsohle sowie eine Zwischensohle und eine in einem Ausschnitt der Zwischensohle befindliche Weichbettung aufweist, und wobei bedarfsweise zur Bildung einer Rolle die Zwischensohle gegebenenfalls mit Weichbettung im Bereich zumindest der Sohlenspitze eine Abschrägung aufweist. Diese Schuhsohle ist insbesondere dadurch gekennzeichnet, daß die Laufsohle, die Zwischensohle und die Weichbettung zu einem vorgefertigten Sandwich-Rohling verbunden sind und daß die Weichbettung mit ihrer der Laufsohle abgewandten Oberfläche über die Oberfläche der Zwischensohle zum Zurückdrücken der Eindellung vorsteht. Durch diese Vorfertigung des Sandwich-Rohlings kann dieser besonders günstig in Serie hergestellt werden, wobei dann nur noch wenige Arbeitsgänge erforderlich sind, wenn der Rohling an einen zuzurichtenden Schuh angebracht werden soll. Vorteilhaft ist weiterhin, daß durch den Überstand der Weichbettung die in der Brandsohle durch eine Fußdruckstelle vorhandene Eindellung weitgehend korrigiert werden kann, da beim Verbinden des Sandwich-Rohlings mit der Brandsohle bzw. dem Zwickeinschlag des Schuhes diese Eindellung zurückgedrückt wird, so daß der Schuh von der Innenseite her wieder weitgehend die ursprüngliche Sohlenform annimmt. Neben einer Korrektur der Einlaufstelle der Brandsohle erhält man dadurch auch eine etwas dickere Polsterung, die auch über einen längeren Zeitraum besser der Belastung standhält.The invention also relates to a shoe sole for orthopedic shoe preparation for shoes which have been damaged during use by a foot misalignment and the like, in particular in the form of an inner sole indentation, the shoe sole having an outsole and a midsole and a soft bedding located in a cutout in the midsole , and if necessary to form a role the midsole has a bevel, optionally with soft bedding in the area of at least the sole tip. This shoe sole is characterized in particular in that the outsole, the midsole and the soft bed are connected to form a prefabricated sandwich blank and that the soft bed, with its surface facing away from the outsole, projects beyond the surface of the midsole to push back the indentation. This prefabrication of the sandwich blank means that it can be mass-produced particularly cheaply, with only a few operations then being required if the blank is to be attached to a shoe to be prepared. It is also advantageous that the protrusion of the soft bedding allows the indentation in the insole to be largely corrected by a foot pressure point, since when the sandwich blank is connected to the insole or the lasting fold of the shoe, this indentation is pressed back, so that the shoe from the inside largely resumes the original sole shape. In addition to correcting the insole's point of entry, this also results in a slightly thicker padding that can withstand the load better over a longer period of time.

Zweckmäßigerweise ist die Weichbettung vom Ausschnitt der Zwischensohle formschlüssig gehalten und/oder durch vorzugsweise punktförmige Klebung z. B. mittels Doppelklebeband od. dgl. mit der Laufsohle oder der Zwischensohle verbunden. Es erfolgt somit nur eine Lagefixierung durch Anheften der Weichbettung. Gegenüber einer sonst vorgesehenen, vollflächigen Klebung hat diese den Vorteil, daß praktisch kein Klebstoff in die Polsterung durch Fußdruck und Wärme eingetreten werden kann, so daß ein Zusammenkleben und Verhärten des Polsterstückes vermieden wird. Auch dadurch kann diewirksame Benutzungsdauer des Schuhes verlängert werden.The soft bedding is expediently held in a form-fitting manner by the cutout of the midsole and / or by preferably punctiform gluing, for. B. od by means of double-sided tape. Like. Connected to the outsole or midsole. There is thus only a positional fixation by tacking the soft bedding. Compared to an otherwise provided, full-surface gluing, this has the advantage that practically no glue can enter the upholstery due to foot pressure and heat, so that the upholstery sticks together and hardens piece is avoided. This can also extend the effective life of the shoe.

Vorteilhafterweise ist die Abschrägung zur Bildung einer Rolle auf der der Laufsohle abgewandten Oberseite der Zwischensohle vorgesehen. Durch die Abschrägung auf der der Laufsohle abgewandten Oberseite kann vor dem Verbinden mit der Unterseite des Schuhes eine besonders gute Anpassung an die Schuhdurchbiegung vorgenommen werden, was ein gutes Abrollen des Schuhes beim Laufen ergibtThe bevel is advantageously provided to form a roller on the upper side of the midsole facing away from the outsole. Due to the bevel on the upper side facing away from the outsole, a particularly good adaptation to the deflection of the shoe can be carried out before the connection to the underside of the shoe, which results in good rolling of the shoe when running

Eine in den Figuren 1 und 2 gezeigte Schuhsohle 1 dient zur orthopädischen Schuhzurichtung und besteht im wesentlichen aus einem Sandwich-Rohling mit einer Laufsohle 2, einer Zwischensohle 3 sowie einer Weichbettung 4.A shoe sole 1 shown in FIGS. 1 and 2 is used for orthopedic shoe dressing and essentially consists of a sandwich blank with an outsole 2, a midsole 3 and a soft bedding 4.

Die Zwischensohle 3 ist im gezeigten Ausführungsbeispiel als Sogenannte verdeckte Schmetterlingsrolle ausgebildet. Eine Solche Zwischensohle 3 kommt bei der orthopädischen Schuhzurichtung insbesondere bei einem Spreizfuß zur Anwendung. Dabei ist im Bereich einer vorhandenen Fuß-Druckstelle eine Aussparung 5 vorgesehen, innerhalb der sich die Weichbettung 4 befindet. Die Fußdruckstelle ist somit durch die Weichbettung 4 gepolstert und ergibt eine elastische Abstützung des Fußes in diesem Bereich.In the exemplary embodiment shown, the midsole 3 is designed as a so-called hidden butterfly roller. Such a midsole 3 is used in orthopedic shoe preparation, in particular with an spreading foot. A recess 5 is provided in the area of an existing foot pressure point, within which the soft bed 4 is located. The foot pressure point is thus padded by the soft bedding 4 and provides elastic support for the foot in this area.

Erfindungsgemäß ist nun vorgesehen, daß die Laufsohle 2, die Zwischensohle 3 und die Weichbettung 4 zu einem vorgefertigten Sandwich-Rohling verbunden sind. Durch diese Vorfertigung ist eine sehr rationelle, zeit- und kostengünstige Bearbeitung möglich. Um den Sandwich-Rohling für unterschiedliche Schuhgrößen einsetzen zu können, ist dieser mit etwas Überstand und bedarfsweise auch in z. B. drei Grundgrößen vorgefertigt. Ein sich bei dem zu bearbeitenden Schuh ergebender Überstand kann dann nach dem Anbringen der Schuhsohle 1 abgeschnitten bzw. abgeschliffen werden.According to the invention, it is now provided that the outsole 2, the midsole 3 and the soft bed 4 are connected to form a prefabricated sandwich blank. This prefabrication enables a very efficient, time and cost-effective processing. In order to be able to use the sandwich blank for different shoe sizes, this is with a little overhang and if necessary also in z. B. three basic sizes prefabricated. A protrusion resulting from the shoe to be processed can then be cut off or ground off after the shoe sole 1 has been attached.

Um beim Gehen in erwünschter Weise ein « Abrollen » des Schuhes zu erzielen, wird die Sohle am vorderen und hinteren Ende zu einer sogenannten Rolle geformt. Da beim bisherigen Verfahren einer orthopädischen Schuhzurichtung die Zwischensohle 3 in einem ersten Arbeitsgang mit dem Schuh verbunden wurde, wurde dementsprechend die Unterseite der Zwischensohle 3 an den Enden zu einer Rolle geformt. Nachteilig ist hierbei, daß die Zwischensohle 3 beim Aufbringen die Schuhbiegung etwas verformt, so daß dann das Rundschleifen nicht mehr so erfolgen kann, wie es eigentlich dem Schuhverlauf als Rolle entsprechen würde. Ein gutes Abrollen des Schuhes beim Gehen kann dadurch beeinträchtigt werden, da hierbei während des « Abrollens von einer Fläche zu einer anderen übergegangen wird und dadurch gegebenenfalls ein « Klappern » auftritt.In order to achieve a «rolling off» of the shoe when walking, the sole is formed into a so-called roll at the front and rear end. Since in the previous method of orthopedic shoe dressing, the midsole 3 was connected to the shoe in a first operation, the underside of the midsole 3 was accordingly formed into a roll at the ends. The disadvantage here is that the midsole 3 deforms the shoe bend somewhat when it is applied, so that the cylindrical grinding can then no longer take place as it would actually correspond to the course of the shoe as a roller. A good rolling off of the shoe when walking can be impaired, since it will move from one surface to another during the «rolling off and this may cause a« rattling ».

Bei Verwendung des erfindungsgemäßen Sandwich-Rohlings kann die Zwischensohle 3 vordem Verbinden mit dem Schuh von der Oberseite her zu einer Rolle geformt werden. In den Fig. 1 und 2 sind gut die im vorderen und hinteren Bereich der Schuhsohle 1 angeschliffenen Übergänge 6 erkennbar, wobei in Fig. 2 das hintere Ende etwas hochgebogen dargestellt ist. Durch das Formen der als Schmetterlingsrolle ausgebildeten Zwischensohle 3 von der Laufsohle 2 abgewandten Seite her ergeben sich günstigere Spannungskräfte zwischen dem Schuh und der Sohle, so daß eine praktisch optimale Anpassung an den unbelasteten Schuhverlauf möglich ist. Die als Sandwich-Rohling ausgebildete Schuhsohle 1 kann sowohl bei. der Neuanfertigung von Schuhen als auch zur nachträglichen orthopädischen Schuhzurichtung verwendet werden.When using the sandwich blank according to the invention, the midsole 3 can be formed into a roll from the top before being connected to the shoe. 1 and 2 clearly show the transitions 6 ground in the front and rear area of the shoe sole 1, the rear end being shown somewhat bent in FIG. 2. By shaping the midsole 3 designed as a butterfly roller, the side facing away from the outsole 2 results in more favorable tension forces between the shoe and the sole, so that a practically optimal adaptation to the unloaded course of the shoe is possible. The shoe sole 1 designed as a sandwich blank can be used for both. the new production of shoes as well as for the subsequent orthopedic shoe preparation.

In den Figuren 2 sowie 5 und 6 ist noch ein besonders vorteilhaftes Merkmal der Erfindung erkennbar. Dieses besteht darin, daß die Weichbettung 4 mit ihrer der Laufsohle 2 abgewandten Oberfläche 7 über die Oberfläche 8 der Zwischensohle 3 vorsteht. Dadurch ist die Möglichkeit gegeben, daß eine durch einen Fußdruckpunkt vorhandene Eindellung insbesondere im Bereich der Brandsohle 9 (vgl. Fig. 3 bis 6) weitgehend ausgeglichen werden kann. Außerdem steht dadurch ein wesentlich dickeres Druckpolster praktisch als Kompressions-Weichbettung zur Verfügung, das auch über einen längeren Zeitraum besser der Belastung standhält. Der Überstand 13 der Kompressions-Weichbettung 4 über die Zwischensohle 3 ist dabei zweckmäßigerweise dem Maß einer bei der Brandsohle 9 vorhandenen Eindellung angepaßt. Die Weichbettung 4 wird vorteilhafterweise nicht vollfächig mit der Laufohle verklebt sondern es genügt bereits, wenn sie von der Aussparung 5 der Zwischensohle formschlüssig gehalten ist und bedarfsweise durch punktförmige Klebung z. B. mittels eines Doppelklebebandes od. dgl. lagefixiert ist. Diese Art der Befestigung der Weichbettung 4 hat gegegenüber einer vollfächigen Klebung den wesentlichen Vorteil, daß ein Eindringen von Klebstoff in die Polsterung vermieden wird. Auch unter dem Einfluß von Fußdruck, Fußwärme und Feuchte wird damit einem Verhärten und Zusammenkleben der Weichbettung 4 entgegenwirkt, so daß auch die wirksame Benutzungszeit des zugerichteten Schuhes dadurch verlängert ist.A particularly advantageous feature of the invention can also be seen in FIGS. 2 and 5 and 6. This consists in the fact that the soft bed 4, with its surface 7 facing away from the outsole 2, projects beyond the surface 8 of the midsole 3. This gives the possibility that a dent caused by a foot pressure point can be largely compensated for, particularly in the area of the insole 9 (see FIGS. 3 to 6). This also means that a much thicker pressure cushion is practically available as a soft compression bed that can withstand the load better over a longer period of time. The protrusion 13 of the soft compression bed 4 over the midsole 3 is expediently adapted to the extent of an indentation present in the insole 9. The soft bed 4 is advantageously not fully glued to the outsole, but it is sufficient if it is held in a form-fitting manner by the recess 5 of the midsole and, if necessary, by punctiform adhesive z. B. od by means of a double-sided adhesive tape. Compared to full-surface gluing, this type of fastening of the soft bed 4 has the essential advantage that penetration of glue into the upholstery is avoided. Also under the influence of foot pressure, foot warmth and moisture thus counteracting hardening and sticking together of the soft bedding 4, so that the effective use time of the prepared shoe is thereby extended.

Die Figuren 4 bis 6 zeigen in drei Phasen den Ablauf einer orthopädischen Schuhzurichtung. In Fig. 4 erkennt man einen im Querschnitt dargestellten Schuh 11, bei dem sich durch eine Fuß- druckstelle eine Eindellung 10 gebildet hat, die bereits zu einer durchgetretenen Laufsohle 2a und Brandsohle 9 geführt hat. In Figur 5 ist der Schuh 11 vorbereitet zum Anbringen des erfindungsgemäßen Sandwich-Rohlings. Dabei ist erkennbar, daß die ursprüngliche Laufsohle 2a abgenommen ist. Die Weichbettung 4 ist so plaziert, daß sie sich im Bereich der Fußdruckstelle und damit auch im Bereich der Eindellung 10 befindet. Wird nun die neue Schuhsohle 1 mit dem Schuh 11 verbunden, so wird zunächst die Eindellung 10 durch die Weichbettung 4 zurückgedrückt, bis sich etwa im Schuhinneren die ursprüngliche Auflageebene 12 einstellt. Man erhält so neben einer Korrektur der Einlaufstelle der Brandsohle auch eine etwas dickere Polsterung, die über einen längeren Zeitraum den auftretenden Belastungen standhält. Neben der in Fig. 1 gezeigten verdeckten Schmetterlingsrolle, können in üblicher Weise auch andere Ausführungsformen z. B. eine verdeckte Winkelrolle mit Weichbettung oder eine Schmetterlingshalbsohle mit Mittelfußweichbettung vorgesehen sein.Figures 4 to 6 show the process of an orthopedic shoe preparation in three phases. 4 shows a shoe 11 shown in cross section, in which an indentation 10 has formed through a foot pressure point, which has already led to a worn outsole 2a and insole 9. In FIG. 5, the shoe 11 is prepared for attaching the sandwich blank according to the invention. It can be seen that the original outsole 2a has been removed. The soft bed 4 is placed so that it is located in the area of the foot pressure point and thus also in the area of the indentation 10. If the new shoe sole 1 is now connected to the shoe 11, the indentation 10 is first pushed back by the soft bedding 4 until the original contact plane 12 is established approximately inside the shoe. In addition to a correction of the insole's entry point, this also provides a somewhat thicker padding that withstands the loads that occur over a longer period of time. In addition to the concealed butterfly roll shown in Fig. 1, other embodiments can be in the usual manner, for. B. a concealed angle roller with soft bedding or a butterfly midsole with soft metatarsal bedding can be provided.

Der Sandwich-Rohling wird im gezeigten Ausführungsbeispiel mit der Oberfläche 8 der Zwischensohle 3 im Außenbereich der Schuhunterseite mit einem Oberlederzwickeinschlag 14 und auch noch etwas mit der Brandsohle 9 verklebt. Die ursprüngliche Laufsohle 2a kann aber auch als Restschicht stehenbleiben und dann als Verbindungsseite für den erfindungsgemäßen Sandwich-Rohling dienen. Im Bereich der Kompressions-Weichbettung 4 erfolgt keine Verklebung. Fig. 3 zeigt einen Schuh 11 nach einer orthopädischen Schuhzurichtung mit Hilfe eines erfindungsgemäßen Sandwich-Rohlings. Dabei Sind gut die Laufsohle 2, die Brandsohle 9 sowie die Weichbettung 4 erkennbar.In the exemplary embodiment shown, the sandwich blank is glued to the surface 8 of the midsole 3 in the outer region of the underside of the shoe with an upper leather wedge 14 and also somewhat to the insole 9. However, the original outsole 2a can also remain as a residual layer and then serve as a connection side for the sandwich blank according to the invention. No gluing takes place in the area of the soft compression bedding 4. 3 shows a shoe 11 after an orthopedic shoe preparation with the aid of a sandwich blank according to the invention. The outsole 2, the insole 9 and the soft bed 4 are clearly visible.

Erwähnt sei noch, daß die Schmetterling-Innenseite um das Großzehenendglied kürzer ausgebildet sein kann, um einen noch besseren Abrollvorgang zu ermöglichen. Auch durch die außen längere Ausbildung der Schuhsohle erhält man eine noch bessere Statik. Alle in der Beschreibung, den Ansprüchen und der Zeichnung dargestellten Merkmale können sowohl einzeln als auch in beliebiger Kombination miteinander erfindungswesentlich sein.It should also be mentioned that the inside of the butterfly can be made shorter around the big toe member in order to enable an even better rolling process. The longer design of the sole of the shoe also results in even better statics. All the features shown in the description, the claims and the drawing can be essential to the invention both individually and in any combination with one another.

Claims (5)

1. A method for the orthopedic adaptation of shoes wherein, in a shoe with a sole damaged inside by a dent and the like formed through faulty posture of the foot during use of the shoe, first one removes the old outsole, at least for the most part, and subsequently applies a new outsole as well as an intermediate sole provided with a cut-out for cushioning in the region of the dent or the like. e. g. a butterfly-like roll, and cushioning between the insole and outsole, characterized in that first a sandwich blank is prefabricated by the new outsole (2) being connected to the intermediate sole (3) and cushioning (4) projecting above the intermediate sole being inserted into the cut-out (5) of the latter and that, in the case of a shoe being applied, the sandwich blank is adjusted to the respective shoe at least with respect to its outline and is subsequently connected to the insole (9) and/or remaining layer of outsole and/or to an infolded welt of upper leather (14) of the shoe (11), the deformation of the dent being at least partly reversed by the projecting cushioning.
2. The method as claimed in claim 1, characterized in that for adapting the sandwich blank "further the latter is abraded from the side averted from the outsole (2), particularly in the area of the tip, in order to form a roll and for adaptation to the flexure of the shoe and the like.
