Definitions
- the invention relates to a shoe, in particular pump, high heel shoe or stiletto, with an insole and a heel, wherein in the heel and / or in the insole, in particular in the heel and / or in the ball area, a damping element is integrated.
- a shoe with arranged in the insole rubber elements is known from US 2007/0151124 A1 .
- Damping soles are used in particular for sports shoes to dampen the forces acting on the body during running and jumping. Since sports shoes have very thick soles, correspondingly large amounts of different damping materials can be used.
- the damping element has a Shore D hardness in the range of 28-33, preferably in the range 28.5 to 29.5, a modulus of elasticity in the range of 28 - 38 MPa, preferably in the range 32nd - 36 MPa, and has a tensile stress of 9-11, preferably 9.5-10.5 MPa at 600% elongation.
- damping elements are referred to below as BSW elastomers (intervertebral disc material) damping elements.
- the BSW cushioning element causes the BSW cushioning element to feel hard on the one hand (in contrast to conventional cushioning elements used in shoes), and under high compressive load, such as those on shoes with high narrow heels, on the other.
- a large part of the introduced energy absorbs and thus causes a relief of the foot, knee joints and the spine.
- the BSW damping elements can also be used effectively in elegant women's shoes with high heels, which was limited possible with conventional soft damping elements, as these either (due to the limited Platzes) have too little damping or (due to the soft material) are too unstable to ensure safe movement in the shoes.
- the BSW damping elements have similar mechanical properties as an intervertebral disc implant.
- pressure differences can be optimally balanced and it is achieved an excellent shock absorption.
- the damping element according to the invention is characterized by a high resilience, a high stress cracking resistance and a high abrasion resistance. The shoe according to the invention thus enables a damping of the pressure on the forefoot (foot ball) and the heel.
- the BSW damping element is formed as an insole or as part of the insole.
- the BSW damping element thus not only assumes the task of damping but also fulfills (at least in part) the functions of an insole (connection between the outsole and the insole or shoe upper).
- the insole may have at least one recess, wherein in the at least one recess, the / the damping element (s) is / are arranged.

- the advantages of the invention are particularly effective, for shoes with high heels, preferably higher than 9 cm, and / or shoes with small sales areas (Stilettos), preferably 1 cm 2 (Pfennigabsatz), since here on the ball area particularly large forces / pressure or in the heel area a particularly high pressure acts.
- BSW damping elements in the insole can be integrated into the heel in the shoe, "integrated" in the context of the invention not meaning that the damping element must be arranged inside the heel, but rather with further heel elements forms the heel of the shoe.
- the damping element is made of a mixture of at least two thermoplastic elastomers.
- thermoplastic elastomers preferably differ in their Shore D hardness and / or their modulus of elasticity and / or in their tensile stress. Thus, these properties can be specifically influenced by the formulation of the various elastomers and thus adapted to different needs in order to obtain similar mechanical properties as they are found in a human or artificial disc.
- the damping element has a bending modulus of elasticity (modulus of elasticity) in the range from 28 to 38 MPa.
- thermoplastic elastomers are thermoplastic elastomers based on copolymers, in particular with soft polyether segments. Particularly advantageous properties arise, for example, when poly (ether-ester) copolymers with Shore D hardnesses between 25 and 33 in mixing ratios of 70:30 to 30:70, in particular in the ratio 60:40 to 50:50 are used.
- thermoplastic elastomers may also be thermoplastic polyurethanes.

- the section of the heel designed as a BSW damping element is encased annularly.
- the damping element is thus protected against external influences.
- the annular sheath symbolizes the effect of the BWS material and indicates the extension of the disc, which is responsible for the "comfort comfort".
- the sheath can be designed as a cover, for example. Made of leather, or as a removable clip.
- the heel of the shoe can at least partially be made of carbon.
- the paragraph may have a carbon frame construction.
- the invention also relates to the use of a mixture of different elastomers, in particular based on copolymer with polyether soft segments for damping elements in shoes, especially in pumps, high heel shoes or stiletto shoes.
- the BSW damping elements can also be used advantageously in casual shoes, shoes for men, as well as in flat women's shoes, such as ballerinas, with or without a high heel.
- the invention also relates to a method for producing a shoe, in particular a pump, high heel shoe or stiletto shoe, wherein first BSW damping elements are made of a mixture of at least two different elastomers.
- An insole and / or a heel is / are provided with at least one recess into which the damping element is finally inserted and fastened as an integral part of the insole / heel.

- the biomechanics of the BSW material which is unique in the shoe sector, effectively reduces the effect of force on specific load points in the foot and thus provides a remedy for the unpleasant side effects as well as long-term side effects such as, for example, Pressure points and the deformation feet. A wearer can go with help of the invention described here longer without pain in high heels.
- Fig. 1 shows a ladies shoe 1 with a high heel 2.
- the shoe 1 has an insole 3 , which is provided in the ball area and heel area with recesses 4a, 4b .
- damping elements 5a, 5b are arranged in the recesses 4a, 4b .
- the recesses 4a, 4b of the insole 3 are just so large that the damping elements 5a, 5b can be accommodated in the unloaded state.
- the insole 3 with the damping elements 5a, 5b is covered with a sock 9 .
- the paragraph 2 comprises a base body 6, which is interrupted in the lower third by a further recess 4c .

Description
Die Erfindung betrifft einen Schuh, insbesondere Pump, High Heel Schuh oder Stiletto, mit einer Brandsohle und einem Absatz, wobei im Absatz und/oder in der Brandsohle, insbesondere im Fersen- und/oder im Ballenbereich ein Dämpfungselement integriert ist.The invention relates to a shoe, in particular pump, high heel shoe or stiletto, with an insole and a heel, wherein in the heel and / or in the insole, in particular in the heel and / or in the ball area, a damping element is integrated.
Ein Schuh mit in der Brandsohle angeordneten Gummielementen ist bekannt aus
Dämpfungssohle werde insbesondere bei Sportschuhen eingesetzt, um die beim Laufen und Springen auf den Körper einwirkenden Kräfte zu dämpfen. Da Sportschuhe sehr dicke Sohlen aufweisen können entsprechend große Mengen an verschiedenen Dämpfungsmaterialien, eingesetzt werden.Damping soles are used in particular for sports shoes to dampen the forces acting on the body during running and jumping. Since sports shoes have very thick soles, correspondingly large amounts of different damping materials can be used.
Speziell bei eleganten Damenschuhen (High Heels) ist dies jedoch nicht möglich, da das Design den Einsatz von großen Mengen an Dämpfungsmaterial nicht erlaubt. Zudem werden Füße und Gelenke beim Gehen in High Heels anders beansprucht als beim Joggen oder Walken. Frauen, die gerne High Heels tragen, müssen daher mit Nebenwirkungen wie Schmerzen im Vorderfuß ("Ballenbrennen"), Blasen, geschwollene Füße bis zu Langzeitschäden für Gelenke und Rücken leben.However, this is not possible with elegant women's shoes (high heels), as the design does not allow the use of large amounts of cushioning material. In addition, feet and joints are stressed when walking in high heels differently than jogging or walking. Women who like to wear high heels, therefore, have to live with side effects such as pain in the forefoot ("bale burning"), blisters, swollen feet, and even long-term damage to the joints and back.
Es ist bekannt, Geleinlagen an den schmerzenden Stellen in die Schuhe zu legen. Dies beeinträchtigt jedoch meist die Passform der Schuh. Oft werden Geleinlagen als Produkte gegen Rutschen bzw. für ein Mehr an Halt in hohen oder zu großen Schuhen empfohlen. Daneben sollen sie Druckstellen vermeiden helfen und auch an sehr beanspruchten Bereichen Entlastung bewirken Bei den gängigen Geleinlagen handelt es sich zumeist um Silikoneinlagen, deren dämpfende Eigenschaften jedoch eher gering bis nicht vorhanden sind..It is known to put gel deposits on the painful areas in the shoes. However, this usually affects the fit of the shoe. Often, gel deposits as products against chutes or for a greater amount of hold in high or recommended on big shoes. In addition, they should help avoid bruises and cause relief even in very stressed areas. The common gel deposits are mostly silicone inserts, whose damping properties, however, are rather low to nonexistent.
Aus
Es ist Aufgabe der Erfindung einen Schuh, insbesondere einen Damenschuh mit hohem Absatz, vorzuschlagen, der elegant gestaltet, mit einem hochwertigen Design versehen werden kann ohne dass auf Komfort und Bequemlichkeit verzichtet werden muss.It is an object of the invention to provide a shoe, in particular a ladies shoe with a high heel, which can be elegantly designed, provided with a high-quality design without sacrificing comfort and convenience.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Dämpfungselement eine Shore-D-Härte im Bereich von 28-33, vorzugsweise im Bereich 28,5 bis 29,5, ein Elastizitäts-Modul im Bereich von 28 - 38 MPa, vorzugsweise im Bereich 32 - 36 MPa, und eine Zugspannung von 9-11, vorzugsweise von 9,5-10,5 MPa bei 600% Dehnung aufweist. Derartige Dämpfungselemente werden im Folgenden als BSW Elastomeren (Bandscheibenwerkstoff) -Dämpfungselemente bezeichnet.This object is achieved in that the damping element has a Shore D hardness in the range of 28-33, preferably in the range 28.5 to 29.5, a modulus of elasticity in the range of 28 - 38 MPa, preferably in the range 32nd - 36 MPa, and has a tensile stress of 9-11, preferably 9.5-10.5 MPa at 600% elongation. Such damping elements are referred to below as BSW elastomers (intervertebral disc material) damping elements.
Die Kombination dieser Eigenschaften bewirkt, dass sich das BSW-Dämpfungselement einerseits (im Gegensatz zu herkömmlichen in Schuhen verwendeten Dämpfungselementen) hart anfühlt, bei hoher Druckbelastung, wie sie beispielsweise bei Schuhen mit hohen schmalen Absätzen auftreten, jedoch einen großen Teil der eingebrachten Energie aufnimmt und somit eine Entlastung der Fuß-, Kniegelenke und der Wirbelsäule bewirkt. Aufgrund der gewählten Härte und dem sich aus den erfindungsgemäßen Parametern ergebenden Rückstell- und Kraftwirkungsverhalten können die BSW-Dämpfungselemente auch effektiv in eleganten Damenschuhen mit hohen Absätzen eingesetzt werden, was bei herkömmlichen, weichen Dämpfungselementen nur begrenzt möglich war, da diese entweder (aufgrund des begrenzten Platzes) zu wenig Dämpfung aufweisen oder (aufgrund des weichen Materials) zu instabil sind, um ein sicheres Fortbewegen in den Schuhen zu gewährleisten.The combination of these properties causes the BSW cushioning element to feel hard on the one hand (in contrast to conventional cushioning elements used in shoes), and under high compressive load, such as those on shoes with high narrow heels, on the other. However, a large part of the introduced energy absorbs and thus causes a relief of the foot, knee joints and the spine. Due to the selected hardness and resulting from the parameters of the invention restoring and force behavior, the BSW damping elements can also be used effectively in elegant women's shoes with high heels, which was limited possible with conventional soft damping elements, as these either (due to the limited Platzes) have too little damping or (due to the soft material) are too unstable to ensure safe movement in the shoes.
Die BSW- Dämpfungselemente weisen ähnliche mechanische Eigenschaften auf wie ein Bandscheibenimplantat. Durch den Einsatz solcher BSW-Dämpfungselemente in der Brandsohle von Schuhen können Druckunterschiede optimal ausgeglichen werden und es wird eine exzellente Stoßdämpfung erreicht. Insbesondere zeichnet sich das erfindungsgemäße Dämpfungselement durch ein hohes Rückstellvermögen, eine hohe Spannungsrissbeständigkeit sowie eine hohe Abrasionsfestigkeit aus. Der erfindungsgemäße Schuh ermöglicht somit eine Dämpfung des Drucks auf den Vorderfuß (Fussballen) und die Ferse.The BSW damping elements have similar mechanical properties as an intervertebral disc implant. By using such BSW damping elements in the insole of shoes pressure differences can be optimally balanced and it is achieved an excellent shock absorption. In particular, the damping element according to the invention is characterized by a high resilience, a high stress cracking resistance and a high abrasion resistance. The shoe according to the invention thus enables a damping of the pressure on the forefoot (foot ball) and the heel.
Bei einer speziellen Ausführungsform ist das BSW-Dämpfungselement als Brandsohle oder als Teil der Brandsohle ausgebildet. Das BSW-Dämpfungselement übernimmt also nicht nur die Aufgabe der Dämpfung sondern erfüllt (zumindest teilweise) auch die Funktionen einer Brandsohle (Verbindung zwischen Laufsohle und Decksohle bzw. Schuhschaft).In a specific embodiment, the BSW damping element is formed as an insole or as part of the insole. The BSW damping element thus not only assumes the task of damping but also fulfills (at least in part) the functions of an insole (connection between the outsole and the insole or shoe upper).
Alternativ dazu kann die Brandsohle mindestens eine Ausnehmung aufweisen, wobei in der mindestens einen Ausnehmung das/die Dämpfungselement(e) angeordnet ist/sind. Die Brandsohle besteht vorzugsweise aus einem gängigen Brandsohlenmaterial, z.B. Leder, Lederfaserstoffe, Kunstfasergewebe etc..Alternatively, the insole may have at least one recess, wherein in the at least one recess, the / the damping element (s) is / are arranged. The insole is preferably made of a common insole material, such as leather, leather fabrics, synthetic fabric, etc ..
Die Vorteile der Erfindung kommen besonders gut zur Geltung, bei Schuhen mit hohen Absätzen (High Heels), vorzugsweise höher als 9 cm, und/oder Schuhen mit kleinen Absatzflächen (Stilettos), vorzugsweise 1 cm2 (Pfennigabsatz), da hier auf den Ballenbereich besonders große Kräfte/Druck beziehungsweise im Absatzbereich ein besonders hoher Druck wirkt.The advantages of the invention are particularly effective, for shoes with high heels, preferably higher than 9 cm, and / or shoes with small sales areas (Stilettos), preferably 1 cm 2 (Pfennigabsatz), since here on the ball area particularly large forces / pressure or in the heel area a particularly high pressure acts.
Zusätzlich zu den BSW-Dämpfungselementen in der Brandsohle können bei dem erfindungsgemäßen Schuh weitere BSW-Dämpfungselemente im Absatzes integriert sein, wobei im Rahmen der Erfindung "integriert" nicht bedeutet, dass das Dämpfungselement im Innern des Absatzes angeordnet sein muss, sondern vielmehr mit weiteren Absatzelementen den Absatz des Schuhs bildet.In addition to the BSW damping elements in the insole, further BSW damping elements can be integrated into the heel in the shoe, "integrated" in the context of the invention not meaning that the damping element must be arranged inside the heel, but rather with further heel elements forms the heel of the shoe.
Vorzugsweise ist das Dämpfungselement aus einer Mischung aus mindestens zwei thermoplastischen Elastomeren hergestellt.Preferably, the damping element is made of a mixture of at least two thermoplastic elastomers.
Vorzugsweise unterscheiden sich die thermoplastischen Elastomere in ihrer Shore-D-Härte und/oder ihrem Elastizitätsmodul und/oder in ihrer Zugspannung . Somit können diese Eigenschaften durch die Formulierung der verschiedenen Elastomere gezielt beeinflusst und somit an verschiedene Bedürfnisse angepasst werden, um ähnliche mechanische Eigenschaften zu erhalten wie sie in einer menschlichen bzw. künstlichen Bandscheibe zu finden sind.The thermoplastic elastomers preferably differ in their Shore D hardness and / or their modulus of elasticity and / or in their tensile stress. Thus, these properties can be specifically influenced by the formulation of the various elastomers and thus adapted to different needs in order to obtain similar mechanical properties as they are found in a human or artificial disc.
Besonders vorteilhaft ist es, wenn das Dämpfungselement ein Biege-Elastizitäts-Modul (E-Modul) im Bereich von 28 - 38 MPa aufweist.It is particularly advantageous if the damping element has a bending modulus of elasticity (modulus of elasticity) in the range from 28 to 38 MPa.
Bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Schuhs handelt es sich bei den thermoplastischen Elastomeren um thermoplastischen Elastomere auf Copolymer-basis, insbesondere mit Polyether-Weichsegmenten. Besonders vorteilhafte Eigenschaften ergeben sich beispielsweise, wenn Poly(ether-ester) Copolymere mit Shore D-Härten zwischen 25 und 33 in Mischungsverhältnissen von 70:30 bis 30:70, insbesondere im Verhältnis 60:40 bis 50:50 verwendet werden.In a particularly preferred embodiment of the shoe according to the invention, the thermoplastic elastomers are thermoplastic elastomers based on copolymers, in particular with soft polyether segments. Particularly advantageous properties arise, for example, when poly (ether-ester) copolymers with Shore D hardnesses between 25 and 33 in mixing ratios of 70:30 to 30:70, in particular in the ratio 60:40 to 50:50 are used.
Alternativ hierzu kann es sich bei den thermoplastischen Elastomeren auch um thermoplastischen Polyurethane handeln.Alternatively, the thermoplastic elastomers may also be thermoplastic polyurethanes.
Die BSW-Dämpfungselemente werden vorzugsweise mittels Extrusion in einem Spritzgussverfahren hergestellt.The BSW damping elements are preferably produced by extrusion in an injection molding process.
Vorzugsweise sind die BSW-Dämpfungselemente fest in der Brandsohle fixiert, insbesondere verklebt.Preferably, the BSW damping elements are firmly fixed in the insole, in particular glued.
Vorzugsweise ist zumindest ein BSW-Dämpfungselement in der Brandsohle integriert, d.h. die Brandsohle weist eine Ausnehmung auf, in welche das Dämpfungselement derart eingesetzt wird, dass das Dämpfungselement mit der Brandsohle abschließt. Die Tiefe der Ausnehmung und die Dicke des Dämpfungselements sind also aufeinander abgestimmt. Dazu ist es vorteilhaft, wenn das Dämpfungselement eine konstante Dicke von einigen Millimetern, insbesondere ≤ 5,5 mm, vorzugsweise ≤ 3 mm aufweist. Durch die erfindungsgemäßen BSW-Dämpfungselemente kann auch mit einer solchen geringen Dicke noch eine effektive Dämpfung erreicht werden. Durch Verwendung von BSW-Dämpfungselementen mit konstanter Dicke wird das Tragegefühl des Schuhs durch die Form der Dämpfungselemente nicht negativ beeinflusst. Die Trägerin spürt und sieht die BSW-Dämfpungselement nicht, da diese integraler Bestandteil der Brandsohle sind und mit deren Oberfläche abschließen.Preferably, at least one BSW damping element is integrated in the insole, i. the insole has a recess into which the damping element is inserted such that the damping element terminates with the insole. The depth of the recess and the thickness of the damping element are thus coordinated. For this purpose, it is advantageous if the damping element has a constant thickness of a few millimeters, in particular ≦ 5.5 mm, preferably ≦ 3 mm. By means of the BSW damping elements according to the invention, even with such a small thickness, an effective damping can still be achieved. By using BSW damping elements of constant thickness, the wearing comfort of the shoe is not adversely affected by the shape of the damping elements. The wearer does not feel and does not see the BSW damping elements, as they are an integral part of the insole and close with their surface.
Bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Schuhs ist der Absatz abschnittsweise als Dämpfungselement ausgeführt, welches zwischen zwei Teilen eines Absatzgrundkörpers angeordnet ist.In a particularly preferred embodiment of the shoe according to the invention, the heel is executed in sections as a damping element, which is arranged between two parts of a heel base.
Bei einer besonders bevorzugten Ausführungsform weist das Absatz-Dämpfungselement eine durchgehende vertikale Ausnehmung auf, durch die ein Fixierungselement zum Fixieren des Absatz-Dämpfungselement an den beiden Teile des Absatz-Grundkörpers 6 durchgeführt werden kann.In a particularly preferred embodiment, the heel-damping element has a continuous vertical recess, through which a fixing element for fixing the heel-damping element to the two parts of the
Das Absatz-BSW-Dämpfungselement hat vorzugsweise eine Dicke von einigen Millimetern, insbesondere mindestens 5,5mm.The heel BSW damping element preferably has a thickness of a few millimeters, in particular at least 5.5 mm.
Besonders vorteilhaft ist es, wenn der als BSW-Dämpfungselement ausgebildete Abschnitt des Absatzes ringförmig ummantelt. Das Dämpfungselement ist somit vor äußeren Einflüssen geschützt. Darüber hinaus symbolisiert die ringförmige Ummantelung die Wirkung des BWS-Materials und deutet die Verlängerung der Bandscheibe an, die für den "Bequem-Komfort" verantwortlich ist. Die Ummantelung kann als Überzug, bspw. aus Leder, oder als abnehmbarer Clip ausgestaltet sein.It is particularly advantageous if the section of the heel designed as a BSW damping element is encased annularly. The damping element is thus protected against external influences. In addition, the annular sheath symbolizes the effect of the BWS material and indicates the extension of the disc, which is responsible for the "comfort comfort". The sheath can be designed as a cover, for example. Made of leather, or as a removable clip.
Um die Stabilität des Absatzes zu erhöhen kann der Absatz des Schuh zumindest abschnittsweise aus Carbon gefertigt sein. So kann der Absatz beispielsweise eine Rahmenkonstruktion aus Carbon aufweisen.In order to increase the stability of the heel, the heel of the shoe can at least partially be made of carbon. For example, the paragraph may have a carbon frame construction.
Die Erfindung betrifft auch die Verwendung einer Mischung aus verschiedenen Elastomeren, insbesondere auf Copolymerbasis mit Polyether-Weichsegmenten für Dämpfungselemente in Schuhen, insbesondere in Pumps, High Heel Schuhen oder Stiletto Schuhen. Die BSW-Dämpfungselemente können jedoch auch vorteilhaft in Freizeitschuhen, Schuhen für Herren, sowie in flachen Damenschuhen, wie Ballerinas, mit oder ohne hohem Absatz eingesetzt werden.The invention also relates to the use of a mixture of different elastomers, in particular based on copolymer with polyether soft segments for damping elements in shoes, especially in pumps, high heel shoes or stiletto shoes. However, the BSW damping elements can also be used advantageously in casual shoes, shoes for men, as well as in flat women's shoes, such as ballerinas, with or without a high heel.
Die Erfindung betrifft auch ein Verfahren zu Herstellung eines Schuhs, insbesondere eines Pump, High-Heel Schuhs oder Stiletto Schuhs, wobei zunächst BSW-Dämpfungselemente aus einer Mischung von mindestens zwei verschiedenen Elastomeren hergestellt werden. Eine Brandsohle und/oder ein Absatz wird/werden mit mindestens einer Ausnehmung versehen, in die schließlich das Dämpfungselement als integraler Bestandteil der Brandsohle/Absatzes eingebracht und befestigt wird. Dazu wird das BrandsohlenMaterial zunächst auf die Leisten aufgewalkt und beschnitten. Die Materialstärke (Dicke) der Brandsohlen entspricht dabei der der BSW-Dämpfungselemente. An den Belastungsstellen unter Ferse und Ballen werden die Brandsohlen eingeschnitten, so dass diese Teile der Brandsohlen herausgenommen werden können. Die dadurch entstehenden Aussparungen werden so bearbeitet, dass die BSW-Dämpfungselemente passgenau eingesetzt werden können. Im Ballenbereich werden dann die passenden Dämpfungselemente eingeklebt. Im Fersenbereich hingegen werden vorerst die ausgeschnittenen Teile des Grundkörpers der Brandsohle wieder eingelegt (ev. nur leicht an den Schnittflächen verklebt, so dass sie bei der weiteren Anfertigung der Schuhe nicht herausfallen aber wieder zerstörungsfrei entnommen werden können). Dies ist sehr wichtig, da die Absätze später nach dem Ausleisten durch die Brandsohle verschraubt werden müssen, ohne das Dämpfungselement zu verschrauben, um die dämpfenden Eigenschaften nicht zu beeinträchtigen. Nach Einbringung einer Ausballung und Montage der Absätze werden Sohlen aufgebracht und die Schuhe werden ausgeleistet. Anschließend werden im Fersenbereich die aus der Brandsohle eingeschnittenen Teile heraus gehoben. Die Absätze werden durch die Brandsohlen verschraubt, die Dämpfungselemente in die entsprechenden Aussparungen eingefügt und verklebt. Die Decksohlen werden eingeklebt.The invention also relates to a method for producing a shoe, in particular a pump, high heel shoe or stiletto shoe, wherein first BSW damping elements are made of a mixture of at least two different elastomers. An insole and / or a heel is / are provided with at least one recess into which the damping element is finally inserted and fastened as an integral part of the insole / heel. For this, the insole material is first rolled on the strips and trimmed. The material thickness (thickness) of the insoles corresponds to that of the BSW damping elements. The insoles are cut at the points under heel and bale, so that these parts of the insoles can be removed. The resulting recesses are machined so that the BSW damping elements can be used accurately. In the ball area then the appropriate damping elements glued. In the heel area, however, for the time being, the cut-out parts of the main body of the insole are re-inserted (possibly only slightly glued to the cut surfaces, so that they do not fall out in the further preparation of shoes but can be removed non-destructively). This is very important as the heels must later be bolted through the insole after being squeezed out without screwing the cushioning member so as not to compromise the cushioning properties. After introducing a balancing and assembly of heels soles are applied and the shoes are auseistet. Subsequently, the parts cut out of the insole are lifted out in the heel area. The heels are screwed through the insoles, the damping elements inserted into the corresponding recesses and glued. The insoles are glued.
Der erfindungsgemäße Schuh umfasst eine Sohle mit BSW-Dämpfungselementen zur Druckabsorption, die in die Brandsohle integriert oder Teil der Brandsohle, wobei die BSW-Dämpfungselemente mechanische Eigenschaften eines Bandscheibenimplantats nachahmen und als Brandsohle oder als integraler Bestandteil der Brandsohle bewirkt, dass insbesondere High-Heels über längere Zeit mit hohem Tragekomfort und Bequemheit getragen werden können. Die im Schuhbereich einzigartige Biomechanik des BSW-Materials bewirkt eine effektive Reduktion der Krafteinwirkung auf bestimmte Belastungspunkte im Fuß und schafft damit Abhilfe für die unangenehmen Begleiterscheinungen sowie langfristigen Nebenwirkungen wie z.B. Druckstellen und die Deformation Füße. Eine Trägerin kann mit Hilfte der hier beschriebenen Erfindung länger ohne Schmerzen in High Heels gehen.The shoe according to the invention comprises a sole with BSW damping elements for pressure absorption integrated into the insole or part of the insole, the BSW cushioning elements mimicking mechanical properties of an intervertebral disc implant and acting as an insole or as an integral part of the insole, in particular high heels on be worn for a long time with high comfort and comfort. The biomechanics of the BSW material, which is unique in the shoe sector, effectively reduces the effect of force on specific load points in the foot and thus provides a remedy for the unpleasant side effects as well as long-term side effects such as, for example, Pressure points and the deformation feet. A wearer can go with help of the invention described here longer without pain in high heels.
