Description

Footbed for shoes

The present invention relates to a footbed for footwear, in particular for a high heel shoe, comprising a sole-shaped body, such as a flat insert, with a forefoot, a metatarsal and a rear foot, and arranged with at least one arranged on a flat top th raised to support a foot.

Background of the invention

Shoes with a heel area that is much higher than a forefoot, so-called heel shoes, have been very popular for many years, especially for ladies. For example, heel shoes may be defined by the hindfoot area being at least 2 cm higher than the forefoot area. While in flat shoes the weight of a person or the pressure on the human foot pressure is mostly distributed evenly on the forefoot, midfoot and hindfoot area, with heel shoes the main load focuses primarily on the forefoot area due to the increased heel position. Especially with extremely high and thin heel shoes, especially the front part of the foot, that is the ball of the foot, is loaded. This uneven distribution of pressure on the foot often leads to high heel shoes when worn, especially in comparison to flat shoes uncomfortable and uncomfortable. Due to the extreme inclination of the foot, prolonged wear can cause uncomfortable pain not only on the foot, but also in the knee, back and neck area of a person and often lead to long-term medical damage. It is known that with a specific footbed a certain amount of local support of the foot and thus an improved pressure distribution under the foot can be achieved.

US 2004/0211086 A1 discloses, for example, an insole for a heel shoe in which the pressure distribution on a tread surface of a foot is adjusted by means of a sickle-shaped elevation for supporting a heel and a circular elevation arranged in the metatarsal area for supporting a metatarsus can be at least partially displaced from the forefoot area in the direction of the middle and hindfoot area.

Despite intensive efforts to improve the wearing comfort of a heel shoe, the usually individually and independently arranged elevations of a footbed usually only purely mechanically supportive, so that it still leads to locally stronger and weaker pressure-loaded areas and thus to unpleasant pressure points can come. In particular, such "step-like" or "terrace-forming" elevations formed centrally in the obliquely formed metatarsal area of the heel shoe for supporting individual metatarsal areas may lead to locally occurring pressure pains due to the high sensitivity in this area. In addition, such elevations may prevent or at least restrict even walking of the foot when walking.

OBJECT OF THE INVENTION It is therefore an object of the present invention to provide a footbed for a shoe which improves at least one of the abovementioned disadvantages and, in particular, enables a uniform pressure distribution on the tread surface with a simultaneously improved rolling behavior. According to the invention this object is achieved by a footbed with the features of the main claim and by a shoe having the features of claim 17. Advantageous embodiments and further developments of the invention are disclosed in the subclaims, the description and the figures. Further, exemplary methods for making and installing the footbed are suggested which allow to combine an elegant and high-quality design of the shoe with maximum comfort and long-term orthopedic compatibility. Description of the invention

The footbed according to the invention has a base body which has in the midfoot area a first elevation in the area of an inner foot side (medial) and a second elevation in the area of an outer foot side (lateral). The elevations each preferably have a convex upper side and each form a pressure-increased zone, whereby both a mechanical support of individual foot areas and a stimulation of individual nerve cells and muscles of the foot serving for positioning and rolling movement can be effected. The thickness of the ridges is dependent on the relative base thickness of the sole thickness, however, the ridges may be positioned on an insole of a shoe even without a connecting through sole base. In particular, the pressure acting on the foot not only in its longitudinal extent but also transversely to the longitudinal extension can be distributed in an advantageous manner targeted to almost the entire foot contact surface, especially in the forefoot and hindfoot area. The elevations are preferably offset in the longitudinal extent of the base body to each other. In particular, the first elevation may be arranged in an area of the base body such that its highest point is located below the projection of the medial heel bone (sustentaculum tali) when resting one foot, and the second elevation in a region of the base body in which it rests Foot the distal end of the fifth metatarsal bone (metatarsalia) is arranged. The second increase thereby preferably acts as a lateral abutment to the first increase. As a result of this particular, mutually opposite arrangement of the elevations, an active surface pair can be formed which has a width over the entire width and length of the foot, in particular in the forefoot and hindfoot region. shared pressure load and improved, especially those of a flat shoe resembling, rolling movement of the foot while walking allows. Furthermore, a rolling curve can be achieved, which runs clearly s-shaped, in particular from the first elevation arranged on the inner foot side to the outside on the outside foot side second elevation and then back to the arranged on the inside foot area, in which the metatarsophalangeal joint is applied. As a result, in particular an occurrence on only the medial forefoot, also called "heel", can be avoided and an improved gait can be achieved. [Erfindungsgemäße Die] The arrangement and combination of the elevations thus surprisingly brings about both an improved pressure distribution and an improved foot motor.

Preferably, the first elevation extends from the midfoot region to the hindfoot region. Particularly preferably, the first increase in the longitudinal extent of the base body is in each case identical, in particular half and / or symmetrically, in the midfoot region and the rearfoot region. As a result, the first increase in their longitudinal extent may differ significantly from the longitudinal arch supports known to the person skilled in the art, whose longitudinal center of gravity and / or in their longitudinal extension generally leads much further forward. As a result of this particular embodiment according to the invention, the pressure load in the heel region can be transferred from the middle of the heel region into an edge region, so that the pressure distribution, in particular transversely to the longitudinal extension of the main body, can be distributed to almost the entire contact surface even in the heel region. Furthermore, a gripping of the heel in the longitudinal extension of the main body behind the increase can be avoided, so that the increase is perceived as relatively comfortable.

Preferably, the first elevation is formed exclusively in a half of the main body directed toward the rear foot region in the longitudinal extension of the main body, and the second elevation is formed exclusively in a half of the main body directed longitudinally to the forefoot region. As a result, a particularly uniform pressure distribution in the forefoot and hindfoot region can be achieved in an advantageous manner. Preferably, the first elevation is sickle-shaped and extends along an inner leg side edge in the longitudinal extent of the base body, a highest point of the elevation preferably being arranged in the region of the inner leg side edge, in particular below the sustentaculum tali of a foot located on the footbed. Particularly preferably, the first increase in the direction of Innenfußseitenkante is continuously increasing, the corners of the sickle shape preferably lie on the Innenfußseitenkante so that the particular circular, semi-circular or elliptical elevation extending in the direction of a longitudinal axis of the body. As a result, the pressure distribution in the rear foot region can be increased and the pressure sensation at the elevation can be improved. It should also be emphasized that deliberately punctiform support on the medial inside of the footbed not only leads to a pressure retraction, but also to a horizontal tilting of the calcaneal bone and, due to this supination, in particular to tensing of the longitudinal musculature in the arch of the foot again in a deliberately increased load on the plantar foot muscles and forefoot outer edge precipitates.

The first elevation preferably has a longitudinal tilt formed in the longitudinal extension of the base body and a transverse tilt formed transversely to the longitudinal extent of the base body. In particular, according to an exemplary, biaxial tilt, the upper-side contour of the base body can be tilted at least in sections by a first angle and by a second angle from the horizontal, wherein the first angle leg is rotated about an axis of rotation at a positive angle between 20 and 35 degrees, which may be arranged substantially parallel to the longitudinal axis of the base body, and the second angle leg is rotated at a positive angle between 2 and 22 degrees about a second axis of rotation, which is arranged substantially parallel to a transverse axis of the base body. As a result, the pressure distribution can be increased and the pressure sensation at the elevation can be improved. In particular, a pressure load or a pressure which would act without the increase on the forefoot can be absorbed in the side area of the hindfoot area. Preferably, the first elevation is formed such that the area of the first elevation projected on a horizontal plane is 5% to 25% of that on the horizontal plane projected area of the entire body forms. As a result, a particularly effective pressure distribution can be achieved and the pressure sensation at the elevation can be improved. Preferably, the second elevation is substantially rectangular, round, semicircular, trapezoidal or elliptical, and increasingly formed in the direction of an outside foot side edge. Particularly preferably, the second increase to a Außenfußseitenkante continuously rising or concave upper contour. As a result, in particular the fourth and fifth metatarsal bones of a foot arranged in this area can be slightly raised, so that a pressure which would act exclusively on a partial area of the forefoot area, in particular the inner foot area, would at least partially coexist with the outer edge area of the foot can be absorbed, and thereby the overall pressure distribution can be improved. Surprisingly, it has been found that such pressure absorption in the front outer foot area acts as compensation for the pressure absorbed by the first elevation in the rear inner foot area and thereby essentially centers the centerline axis of the body weight in comparison to a shoe without such a second elevation. The interaction of first and second elevation not only achieves a more uniform pressure distribution in the direction of the longitudinal and transverse axis, but also a more stable and more fluid rolling action of the foot, which substantially relieves the foot and knee joints which are normally heavily overloaded in heel shoes brings with it.

Preferably, a material thickness of the base body is made larger in the region of the first elevation than in the region of the second elevation. In particular, the first elevation orthogonal to a flat underside of the base body may be designed to be higher than the second elevation. This is particularly advantageous, since the compressive forces occurring in the area of the first elevation, in particular the hindfoot area, are usually greater than the compressive forces occurring in the area of the second elevation, in particular the lateral foot area. Preferably, at least one additional third elevation is arranged in the midfoot region. The third increase can serve in particular for the retro-capital support of a foot. The third increase is preferably arranged centrally in the front metatarsal region, in the transverse extension of the basic body. In particular, the third increase relative to the longitudinal axis of the basic body can be formed in half in each case in a lateral foot-side area and a medial foot-side area. The third increase is formed tear-shaped or triangular in particular in the longitudinal direction. Particularly preferably, the third elevation is arranged in the region of the basic body in which the second and third metatarsal bones are arranged in the case of a foot located on the basic body. This can be effected both a mechanical support of individual foot areas as well as a stimulation of individual to the position of the foot and thus for pressure distribution in the shoe serving nerve cells. In particular, by means of the third increase, an activation of the longitudinal vaulting musculature of the foot can be triggered, which is necessary for a healthy unrolling of the foot.

Preferably, the base body in the region of the third increase in a homogeneous material thickness. In particular, the base body has a constant material thickness in the region of the third elevation. This is preferably done by a arranged on the underside of the body concave recess. As a result, a transverse axis which preferably passes through the third elevation in the center acts as a bending or rotation axis for the footbed, so that in particular when the foot rolls when walking, the footbed and optionally also the shoe can buckle in the longitudinal direction about the bending axis. This causes a similar feeling on the foot as with a flat shoe.

Preferably, at least one forefoot elevation is additionally arranged in the forefoot area. As a result, a pressure force acting in particular in the direction of the forefoot can be absorbed by the foot in the proximal toe area.

Preferably, a first forefoot elevation is designed as a toe gripper and comprises a crescent-shaped arch which extends substantially over an entire width of the main body. The toe gripper has a bead-like Liehe shape and is preferably formed in that region of the base body in which, in a foot located on the base of the first, second, third, fourth and fifth proximal toe bones (phalanx proximalis) is arranged. In particular, the toe gripper extends between the lateral and medial foot side region of the main body, in particular of the region in which the first and / or second toe bone is arranged when the foot is on the main body, obliquely to the proximal to the outer foot side edge of the main body. The toe gripper can be designed such that it protrudes into a Fußzehenwölbung. As a result, a pressure force acting in the direction of the forefoot can already be absorbed by the foot in the proximal toe area, so that the compressive load can be displaced further to the rear in the longitudinal extent of the basic body.

Preferably, the base body has an additional bulge on a flat underside, in particular in the forefoot area, which is preferably used in high heel shoes with plateau. The bulge is nothing else than a protruding on the underside of the body elevation, in particular a arranged on the bottom second forefoot increase, which is preferably collected by a corresponding recess in the material of the plateau. As a result, the base body in the region of the bulge to form a pressure-reduced zone at a flat top on an increased thickness of the softer compared to the plateau of the heel shoe sole material. The bulge serves as a metatarsophalangeal shock absorber, which further promotes the pressure absorption in the lateral forefoot area in comparison to the medial forefoot area and thereby contributes indirectly to the improved foot motor function. The bulge is preferably arranged in such a way that, when the foot is on the base, the metatarsophalangeal damper, viewed from the vertical projection, is arranged in the distal region of the first and second metatarsal bones.

Preferably, the main body and the elevations are constructed as a unit of a homogeneous substance or mixture of substances. The main body can be made, for example, of a viscoelastic material or of a polypropylene or plastic, in particular polyurethane or ethylene-vinyl acetate. The homogeneous substance or substance mixture can be in a locally different Density in the body, so that one or more zones in the footbed can be designed with different material properties. The density distribution may in particular be such that the footbed in the hindfoot region has a greater hardness than in the forefoot region, and / or that the footbed in the hindfoot region has a lower elasticity than in the forefoot region. In particular, the footbed may be softer or more elastic in its hardness or material density in the forefoot region and harder or less elastic in the hindfoot region and in particular a preferred Shore hardness of 20 plus / minus 10 Shore A in the forefoot region and 50 plus / minus 10 Shore A in the hindfoot area. Thus, the footbed in a relatively simple manner and inexpensive to produce. This is particularly advantageous if the footbed is intended for mass production or as ready-to-wear.

Preferably, the elevations are each formed by a separate element arranged on the main body, in particular as a locally arranged gel storage. In particular, the first elevation, the second elevation, the third elevation, the toe gripper and / or the metatarsophalangeal shock absorber may be formed as one or more separate elements which are placed on a midsole of the shoe without direct connection with each other and / or as separate elements with the Basic body are connected. As a result, the arrangement of the elevations on the base body can be made individually for each foot according to individually determined specifications of a foot geometry. As a result, a particularly effective mechanical support of individual foot areas as well as a particularly effective stimulation of individual nerve cells serving for the position of the foot and thus for the pressure distribution in the shoe can be effected.

In a particularly preferred embodiment, it is provided that at least the main body and / or individual of the two-dimensional elevations is produced by means of a 3D printing method known per se, in particular using plastic as a production material. In such a method, in particular first an optical and / or pressure measuring of the foot can be carried out. Subsequently, the footbed is made individually according to the previously acquired data of the foot, in particular the size and the position of the elevations can be adjusted absolutely and / or relative to each other individually according to the previously determined specifications. This can For example, the highest point of the first elevation can be arranged immediately below the sustentaculum tali of a respective foot. As a result, the footbed can be made particularly individual, automatic and thus particularly cost-effective.

The shoe according to the invention, in particular high heel shoe, has a footbed with at least one of the aforementioned features, in particular a base body having in the midfoot area a first elevation in the region of an inner foot side and a second elevation in the region of an outer foot side.

In the presence of an increase or bulge on an insole formed on the flat underside of the footbed, the shoe preferably has a recess corresponding to the convexity of the footbed for receiving the bulge. As a result, the footbed basic body can advantageously have a pressure-reduced zone in the region of the bulge.

Embodiments of the invention will be explained in more detail with reference to the figures. 1 shows a plan view of an inventive footbed;

and

Figures 3a and 3b are each a comparative representation of the pressure load in a conventional footbed and the footbed according to the invention.

FIG. 1 shows a schematic plan view of the footbed 1 according to the invention. The footbed 1 has a sole-shaped basic body 2, which is essentially adapted to the dimensions of a human foot 100. The foot 100 located on the base body 2 is shown here in an X-ray view with visible bones. The main body 2 has a forefoot region 21, a midfoot region 22 and a rearfoot region 23. The forefoot region 21 extends in the longitudinal direction of the main body 2 from a distal end of the toes to approximately a distal region of the metatarsal bones. The midfoot region 22 extends in the longitudinal direction of the main body 2 approximately from the distal metatarsal bone to a distal end of the heel joint. The hindfoot region 23 extends in the longitudinal direction of the main body 2 approximately from the distal end of the heel joint to the proximal end of the heel. The main body 2 has a distal or front half 28 separated by a transverse transverse axis to the longitudinal extent of the base body 2 and a proximal or rear half 29, wherein the median transverse axis M is arranged approximately in the region of the proximal metatarsals. Furthermore, the base body 2 has a lateral outer foot side 26 separated by a longitudinal axis L and a medial inner foot side 27.

The main body 2 has on a flat upper surface 24 a plurality of elevations 3, 4, 5, 6, 7, which cause in the inventive arrangement and combination both an improved pressure distribution and improved foot motor skills.

A first elevation 3 is arranged on the inner foot side 27 in the midfoot region 22 on the main body 2. The first elevation 3 is designed as a pressure-increased zone and can bring about both mechanical support of the foot 100 and stimulation of muscles and nerve cells. The first elevation 3 is arranged in particular in that region of the basic body 2 in which, when the foot 100 is resting on the basic body 2, the projection of the medial heel bone (sustentaculum tali) is arranged. The first elevation 3 is sickle-shaped and extends along the longitudinal axis L, in particular along the inner foot side 27, to substantially equal parts from the midfoot region 22 to the rearfoot region 23. Here, the first elevation 3 is in the direction of an inner foot lateral edge 27a increasingly formed, with the highest point of elevation 3 just below the sustentaculum tali of the medial calcaneal bone. The corner points of the crescent-shaped first elevation 3 lie on the inner foot side edge 27a. This can the pressure distribution in the heel area is increased and the pressure sensation at the elevation 3 is improved.

The first elevation 3 has a longitudinal tilt formed in the longitudinal extent of the main body 2 and a transverse tilt formed transversely to the longitudinal extent of the body.

The longitudinal tilting of the first elevation 3, as can be seen in particular in FIG. 2a, is designed such that an angle (a) between a straight line A1 connecting the uppermost point 24 in the rearfoot area 23 and the lowest point 91 in the forefoot area 21 and an angle .alpha the longitudinal axis L of the footbed 1 projected between the lowest point 93 in the rear foot 23 and a formed on a Innenfußseitenkante 27a of the footbed 1 highest point 31 of the elevation 3 arranged straight line A2 an angle (a) of about 30 ° is formed. The angle can basically assume values between 20 and 35 ° or 30 ° plus / minus 10 °. As a result, a longitudinal tilting of the foot 100 by about 5 ° is achieved at the foot 100 at the contact point. In particular, a foot region located on the base body 2 is thereby arranged exclusively in the region of the first elevation 3, that is to say in the inner foot side region 27, so that an additional compressive force, which would act on the forefoot 21 without the elevation 3, in the side region 27 of the rearfoot region 23 can be included. The lowest point 91 in the forefoot region 21 is located in particular in that region of the longitudinal axis L of the main body 2, in which the main body 2 starts to rise from the plane of the forefoot region 21 in the direction of the hindfoot region 23.

The transverse tilting of the first elevation 3, as can be seen in particular in FIG. 2b, is designed such that an angle (.beta.) Between a plane E which horizontally intersects the longitudinal axis L and a height which is orthogonal to the longitudinal axis L and an inner foot lateral edge 27a of the footbed 1 Point 31 of the elevation 3 intersecting straight lines A3 an angle (ß) of about 20 ° is formed. In particular, the angle may assume a value between 12 ° plus / minus 10 °. As a result, a transverse tilting of about 3 ° is achieved at the foot 100. In particular, a foot region located on the base body 2 is thereby positioned in the region of the first elevation 3 such that that an additional compressive force, in particular a pressure which would act on a mid-heel region without the rise 3, can be absorbed in the side region 27 of the hindfoot region 23. A second elevation 4 is arranged on the outer foot side 26 in the midfoot region 22 of the main body 2. The second elevation 4 is formed substantially rectangular, trapezoidal or elliptical, wherein the longer edge of the rectangle is arranged substantially parallel to the longitudinal axis L of the base body 2. The second elevation 4 has an upper side contour that rises toward the outer foot side edge 26a and that is concave in the present case, the actual or absolute elevation being relatively small. The second elevation 4 is, in particular, orthogonal to a planar underside 25 of the main body 2, viewed less highly than the first elevation 3. The second elevation 4 is designed in particular as a lateral abutment for the first elevation 3 and can be used as a pressure-increased zone serve for the mechanical support of the foot 100 and in particular for the stimulation of muscles and nerve cells. The second elevation 4 is arranged in particular in that region of the base body 2 in which, when the foot 100 is resting on the base body 2, the distal end of the fourth and / or fifth metatarsal bone is arranged. As a result, a fifth metatarsal bone of a foot 100 arranged in this area can be raised slightly, so that a pressure that would act exclusively on a forefoot and inner foot area without the elevation 4 can be at least partially absorbed by the outer edge area of the foot 100, and thereby the total pressure distribution can be compensated and adapted to the usual in flat shoes s-shaped rolling curve. In the longitudinal extension of the main body 2, the second elevation 4 extends maximally from the proximal end of the fifth metatarsal bone to the proximal region of the fifth proximal toe bone (phalanges proximal).

Due to the formation of the second elevation 4 and the interaction of the mutually oppositely arranged elevations 3 and 4, in particular a rolling curve of the foot 100, not shown here, can be improved while walking. In particular, a clearly s-shaped running rolling curve can be achieved, which is arranged from the inner foot side 27 disposed first Raising 3 laterally outward to the arranged on the Außenfußseite 26 second elevation 4 and then back to the arranged on the Innenfußseite 27 area in which the big toe base joint, extends. As a result, in particular an unpleasant occurrence on only the medial forefoot is avoided. Thus, the recovered rolling motion of the foot, which can be limited in high heel shoes, usually with great effort from the muscles and joints, will allow improved gait. A third elevation 5 is arranged in the central area of the main body 2, in particular in the distal metatarsal area 22. The third elevation 5 is tear-shaped and serves for a retrocapital support of the foot 100. In particular, the third elevation 5 can activate the longitudinal arch musculature of the foot 100, which is required for a healthy Abrol- len of the foot 100. Despite the third increase 5, the base body 2 has a homogeneous material thickness D in this region, in particular by a recess 8 formed on the underside 25 and corresponding to the third elevation 5. For this purpose, the third elevation 5 is convex and the recess 8 is concave , As a result, a preferably centered by the third increase 5 lying, not shown transverse axis as Knickbzw. For example, when walking, the footbed 1 and optionally also an entire shoe can buckle in this area in the longitudinal extent about the bending axis. As a result, the foot 100 may experience a similar sensation as a flat shoe, yet trigger a muscle activating proprioceptor effect to assist the foot's roll-off function. This underside excavation of this type, as well as the unusually small and inconspicuous form of the third elevation, represent a substantial improvement in support compared to conventional metatarsal pads, which are known to the person skilled in the art, especially for use in flat shoes.

A fourth elevation 6, also called forefoot elevation or toe gripper, is arranged in the forefoot area 21 of the main body 2. The toe gripper 6 has a crescent-shaped curvature that extends essentially over the entire width of the toe grip. te of the main body 2 extends. The toe gripper 6 is arranged in particular that region of the main body 2 in which the proximal toe bones 1 to 5 of the foot 100 are arranged. The toe gripper 6 can thereby protrude into a Fußzehenwölbung and there counteract a directed toward the forefoot 21 compressive force, which could result in a high heel without comparable toe gripper that the foot 100 slips too much forward and the first increase 3 no longer optimal below the Sustenaculum Tali. Furthermore, the toe gripper 6 helps to compensate for the increased load on the plantar foot muscles (flexor digitorum brevis), which is triggered by the first elevation 3 and the second elevation 4, by the toe gripper 6 relaxing the flexor tendons via the flexion of the lumbrical muscles thus reaches the forefoot. So it takes the toe gripper 6, so that the foot 100 does not cramp in the encouraged by the remaining increases rolling movement.

A fifth elevation 7 is arranged on the flat underside 25. The fifth elevation 7, also called convexity, serves as a toe joint stabilizer and is nothing more than an elevation projecting on the underside 25 of the main body 2. As a result, the base body 2 in the region of the bulge 7 with a flat upper side 24 has an increased material thickness D for forming a pressure-reduced zone. In particular, the pressure load concentrated on a partial region of the forefoot region 21 can be partially displaced to the entire width of the forefoot region 21 as well as the rear foot region 23 by the big toe joint shock absorber 7 and the general soft and continuous footbed 1. Likewise, the big toe midsole damper 7 and the toe gripper 6 are directly attached to the compensation of the slight lifting of the inside of the foot 27 (supination), which together increase the unrolling of the foot 100 via the great toe joint and "turning it forward". of the foot 100, which has a positive effect on the gait and is compensated by the two elements 7 and 6.

FIGS. 3 a and 3 b show a comparison of the pressure load on the foot 100 when walking a lady with the same heel shoes on the one hand with a conventional footbed S and for comparison on the other hand with the footbed 1 according to the invention. The comparative representations thus show that Result of a practical investigation. The pressure load is represented in each case by dark circles, in particular in the forefoot region 21 by the reference numeral 101 and in the rear foot region 23 by the reference numeral 102.

The footbed S shown on the left half of the illustration in FIG. 3a and the footbed S shown in the right half of the illustration illustrate the pressure load on the footbed S or on the underside of a foot 100 when the conventional footbed S is used In this case, the weight or pressure force acting on the footbed S is concentrated in each case on a small part of the forefoot area 21. In particular, the pressure load in the forefoot area 21 is highest in the area of the first four toes. By contrast, the pressure load in the region of the fifth toe, that is to say on the outside foot side 26 of the forefoot region 21, and in the rear foot region 23 of the conventional footbed S is in each case relatively small. Consequently, the pressure applied to the foot 100 concentrates predominantly on the forefoot area, in particular on the medial forefoot and especially on the distal area of the first and second metatarsal bone. This means that, due to the configuration of the footbed S, an occurrence occurs exclusively with the forefoot and a rolling movement of the foot during walking is almost completely inhibited, so that a so-called "stöckeln" occurs when walking, thereby wearing an heel shoe with such a footbed S in the long term relatively uncomfortable and can cause pain not only at the foot 100, but also due to the malalignment of the foot 100 in the back to the neck of the person wearing the shoe.

The footbed 1 according to the invention shown in Figure 3a on the right half of the illustration and in Figure 3b on the left half of the illustration shows the pressure load when using the same high heel shoe with the footbed 1 according to the invention. Here, the force acting on the footbed 1 pressure force respectively both on the entire area of the forefoot area 21, in particular on an inner foot side edge 27a to an outer foot side edge 26a, as well as on almost the entire area of the rear foot area 23 distributed. Consequently, the pressure applied to the foot 100 is distributed over the entire length and width B of the footbed 1 except for the metatarsal area 22, which is almost unloaded. This means that the design of the footbed according to the invention 1 and in particular by the interaction of the elevations 3, 4, 5, 6, 7 a pressure redistribution away from the medial forefoot towards the hindfoot and a healthy rolling movement of the entire foot 100 can be achieved. In particular, by the elevations 3, 4, 5, 6, 7, and thereby caused slight lifting of the inside of the foot (supination), stimulation or irritation of certain nerve tracts or muscles (proprioception) to improve the rolling motion of the entire foot can be effected. As a result, wearing a heel shoe with such a footbed 1 according to the invention is pleasant and comfortable over a longer period of time.

In the embodiment of the footbed 1 shown in the figures, the main body 2 and the elevations 3, 4, 5, 6, 7 are constructed as a unit of a homogeneous substance mixture. As a result, the production of the footbed is particularly cost-effective. It is envisaged that the main body 2 and the elevations 3, 4, 5, 6, 7 be produced by means of a so-called SD printing method known per se. In this case, the surface contours of the basic body 2 can be adapted individually to a human foot 100. In particular, in this method, first an optical and / or pressure measuring of the foot done. Subsequently, the footbed can be made individually according to the recorded data of the foot. A viscose-elastic material or-preferably in the production of printing-a polypropylene is preferably used as the production material for the main body 2.

It should be clear that the main claim and subclaim are not limited to the example described above, but the footbed or the shoe is designed, manufactured and applicable in the various embodiments. LIST OF REFERENCES:
