EP3661382B1 - Shoe for damping a foot movement via the ankle joint - Google Patents

Description

Technical area

The present invention relates to a shoe for damping foot movement via the ankle.

Background of the invention

It is known to stabilize the movement of the ankle joint by means of orthopedic shoes or devices for limiting foot movements in order to prevent trauma as a result of an ankle twisting, i.e. a movement of the ankle joint over at least one of its ankle joint axes in an unphysiological area. The most common form of ankle trauma is an ankle joint distortion as a stretch or rupture as a result of inversion or supination. Inversion or supination movements over an ankle joint axis result in a change in the distance between the foot and the lower leg due to the increasing inversion or supination angle. If a certain inversion or supination angle or a certain inversion or supination speed or inversion or supination acceleration is exceeded, injuries to the ligamentous apparatus of the ankle or ruptures can occur. In order to prevent this, devices are known which allow movements to a certain extent and which completely prevent movement from a certain critical angle of movement around the ankle joint axis. For this purpose, on the one hand, relatively rigid orthoses are known, in which the inhibition of movements using splints or splint plates is in the foreground.

Furthermore, devices or shoes are known in which a movement of the ankle is permitted up to a certain critical angle of the movement and, due to the structure, a movement is completely blocked from this critical angle. Such a device is, for example, from US Pat EP 2717809 B1 known. Such devices offer No protective effect whatsoever when reaching the critical angle. However, it is known that the risk of injury when twisting an ankle, especially in the case of already weakened ligaments or after an injury, also depends significantly on the inversion or supination speed and the inversion or supination acceleration that occur when an ankle is twisted, and not only on the inversion or supination angle. In the area below the limit (inversion or supination) angle, such devices therefore offer no protection whatsoever. In addition, the movement is completely blocked after the critical angle has been reached. The abrupt stopping of the twisting movement creates a large load on the structure of the ankle joint, which increases the risk of injury, for example a rupture of the bone or a cartilage injury. By blocking the ankle joint, the twisting movement is also transferred to the next joint. If the ankle is twisted, this is the knee joint. Due to the large lever arm present, the unfavorable application of force and the complexity of the knee joint, serious injuries such as cruciate ligament tears or meniscus damage can then lead to more negative effects than ankle ligament injuries due to their limitation of the person, the complexity and the limited healing possibilities.

Furthermore, devices are known which always allow a minimum amount of movement in the tightened state, but block in the event of dangerous movements. From the DE 10 2014 107 335 A1 a device for adaptively limiting an inversion or supination movement via the ankle is shown. The ankle orthosis shown therein requires a pressure-stable bar located on the medial side of the ankle joint, which is located on the medial side of the ankle and is located between the the upper area of the orthosis and the lower area of the orthosis and must be firmly connected to both areas. The bar must be designed in such a way that it guides the tensile forces introduced into the upper area via the pull-out device on the lateral side as compressive forces on the medial side back into the lower area without deforming and buckling. As a result, a position securing in the distal direction is achieved. However, the bar on the medial side of the foot still restricts the freedom of movement of the ankle. Furthermore, it is known to provide a fixation for fixing the upper part to a lower leg instead of the aforementioned support between the upper and lower part on the upper part. Due to the fixation, the upper part is supported in this case from above on the ankle. Due to the support and the fixation, these point Devices have a high weight and a relatively rigid structure and a low level of comfort.

Presentation of the invention

Based on the known prior art, it is an object of the present invention to provide an improved device for damping a foot movement via the ankle joint.

The object is achieved by a shoe for damping foot movement via the ankle joint with the features of claim 1. Advantageous further developments result from the subclaims.

Accordingly, a shoe is proposed for dampening a foot movement via the ankle joint, comprising a shoe sole, an upper connected to the shoe sole, and a damping element for damping a relative movement. A tensile stiff band runs from a first end from a lateral side of the shoe over a shoe heel area and over a medial side of the shoe back to the lateral side to a second end and is movable between the first and the second end on the shoe upper in the direction of its longitudinal extension arranged, wherein the tensile stiff band is fastened with the first end to the cushioning element and is fastened with the second end to the shoe upper. According to the invention, the damping element has a fixed element rigidly connected to the shoe and a relative movement element which is movable relative to the fixed element and is connected to the tension-resistant band. This enables a particularly effective and reliable damping effect to be achieved.

In the present case, the term “lateral side” encompasses an outer side of the shoe. Here, the lateral side of the shoe corresponds to a lateral side of a human foot or a lower human extremity when the latter is wearing the shoe. The "lateral side" is in im worn state of the shoe laterally or turned away from the middle of the wearer's body. In other words, the term “lateral side” includes a lateral side of the human body in the sense of (topographical) anatomy.

Correspondingly, the term “medial side” in the present case includes an inside of the shoe. The medial side of the shoe corresponds to a medial side of a human foot or a lower human extremity when the latter is wearing the shoe. The "medial side" is oriented towards the middle of the body or located in the middle when the shoe is worn. In other words, the term “medial side” includes a medial side of the human body in the sense of (topographical) anatomy.

The “shoe heel area” comprises an area of the shoe in which a heel of a foot is received when it is worn. The shoe heel area therefore corresponds to a rear or dorsal side of the shoe in terms of the (topographical) anatomy of the human body. Consequently, the shoe heel area is opposite to a ventral side.

"Tensile stiff" is to be understood here as any material with which tensile forces can be transmitted. Tensile materials within the meaning of the application can have a certain initial elongation and preferably stiffen above a certain elongation limit value or yield limit value in such a way that the elongation is then greatly reduced compared to the initial elongation or elongation. In the present case, for example, a textile braid made of threads of a tensile stiff material can be used as the tensile stiff band, with the threads of the textile braiding initially experiencing an increasing orientation in the longitudinal extension of the textile braiding when the textile braiding is subjected to tensile load, so that initially a high initial stretching capacity is provided by the orientation of the threads is, and after the alignment of the threads essentially in the direction of force flow, the band has a structure that is rigid in tension.

The term "ankle joint" includes the upper and lower ankle joint and accordingly the axis of movement of the upper ankle joint, which essentially enables plantar flexion and dorsiflexion of the foot, and the axis of movement of the lower ankle joint, which essentially involves inversion and eversion, as well as supination, Adduction and plantar flexion, abduction and dorsiflexion are possible.

The term "ankle" is also understood here to mean the shape of the joint socket, the malleolar fork of the upper ankle joint. Consequently, the term "ankle" in the present case includes the outer ankle, which is formed by the expression of the lateral malleolus, and the Inner malleolus, which is formed by the development of the medial malleolus. Due to the design of the malleolar fork as a joint socket, the ankle has a larger cross-sectional area in relation to the proximal-distal direction compared to the section of the lower leg which is above and consequently proximally connected. The circumference of the ankle is therefore greater in comparison to the proximally adjoining section.

"Shoe" is understood here to mean any form of shoe-like footwear with an upper part or shaft and an associated solid base or sole, in particular orthopedic shoes, sports shoes, casual shoes and boots or sandals. The upper and / or the sole can be designed over the entire surface or only have segments that are necessary for restraint and force transmission in the event of an inversion or supination of the foot. The shoe can also have a sock or a stump made of a textile fabric or knitted fabric as a basic structure, on which segments are arranged on the shoe upper and / or on the sole at least in partial areas, by means of which the segments required to hold the foot in the event of inversion or supination are arranged Forces can be absorbed and passed on.

The term "tape" here generally encompasses an elongated, slack, optionally elastic element, which has the shape of a single fiber, a fiber strand, a wire, a cord, a rope, a textile fabric with a limited width and solid, bilateral selvedges, a hose or may have the like.

In that the tensile stiff band runs from the first end of the lateral side of the shoe over the shoe heel area and over the medial side of the shoe back to the lateral side to the second end and between the first and the second end on the shoe upper in the direction of it Longitudinal extension is movably arranged, wherein the tensile stiff band is attached with the first end to the damping element and the second end is attached to the shoe upper, an inversion or supination movement over the ankle joint can be damped, the movement in every position of the shoe supporting foot can be dampened.

The course of the tensile stiff band from the lateral side over the shoe heel area, the medial side of the shoe back to the lateral side essentially forms a loop, which tensile forces introduced into the ends of the tensile stiff band on the lateral side in the sense of a loop connection according to a Forming line load or area load, the tensile stiff band being supported in the shoe heel area and / or on the medial side and / or partially also on the lateral side. When the shoe is worn, the Line load or surface load correspondingly introduced into the body on the medial side and / or in the heel area of the foot or lower leg of the person wearing the shoe. In other words, the circumferential, tensile band is supported on the medial side and / or in the heel area of the foot or lower leg in the event of an inversion or supination. The forces are essentially transmitted over the entire circumferential length on the medial side, on the shoe heel area and also partially on the lateral side via the shoe upper to the lower extremity of the person wearing the shoe.

The tensile forces acting on the rigid ligament during inversion or supination are distributed over the first end and the second end. Therefore, on the lateral side, part of the tensile forces that arise are transmitted directly to the upper of the shoe via the second end and are absorbed by it. The damping element connected to the first end also only has to absorb or dampen or compensate for part of the forces that arise. The damping element can be made correspondingly smaller than in arrangements known from the prior art, in which the damping element has to absorb all of the forces resulting from inversion or supination.

In the case of an inversion or supination movement, i.e. a twisting, the length of the tension-resistant band between a shoe center longitudinal plane and the first end and between the shoe center longitudinal plane and the second end increases by an angle of inversion or supination around the inversion or supination axis Radians. Since the tensile stiff band is firmly attached to the upper of the shoe at the second end, the above-described change in length of the tensile stiff band in the area of the second end is compensated for by shifting the tensile stiff band in its longitudinal extension on the medial side and the shoe heel area in the direction of the upper part of the second end. In other words, as a result of the inversion or supination relative to the shoe upper on the medial side and the shoe heel area, the rigid band slips over the shoe upper. A relative to the shoe movable part of the damping element, which is attached to the first end, therefore experiences not only a relative movement relative to the part firmly connected to the shoe at the level of the arc dimension resulting from the inversion or supination angle at the first end, but at the level of a Combination of the length of the radian measure resulting from the angle of inversion or supination at the first end plus the displacement of the tensile strip at the second end. With a suitable arrangement or alignment of the tension-stiff band on the lateral side in the area of the first end and the second end, a change in length in radians resulting from the angle of inversion or supination, preferably a double extension path or a doubled length of the relative movement of the movable part to the fixed with the Shoe connected part is created. Correspondingly, even small inversion or supination movements can be damped, since a correspondingly enlarged relative movement occurs on the damping element.

The tension-resistant band is preferably designed to be flexible transversely to its longitudinal extension. This makes it possible for the band to adapt itself circumferentially to the shape and contours of the shoe over its length.

If, according to a further preferred embodiment, a preferably flexible tubular element is arranged on the upper part of the shoe, in which the rigid band is slidably guided at least in sections along its longitudinal extent, the rigid band can be positioned in a particularly stable position with regard to its position on the shoe transversely to its longitudinal extent. In this way, it is possible to specify exactly at which points or which areas of the shoe the forces introduced into the ends of the tension-stiff band due to inversion or supination are transmitted to the upper and to the foot or lower leg. In other words, the position and course of the tape on the shoe upper can be precisely specified.

The tensile stiff band preferably has low friction in the tubular element. For this purpose, the tubular element preferably has a material which has a low coefficient of friction, preferably POM or PTFE. By means of a specific material pairing, the rigid strip can be guided in the tubular element with almost no friction.

According to a further preferred embodiment, at least one preferably flexible positioning element is provided on the upper side of the shoe for positioning the stiff band on the upper side of the shoe, so that the stiff band can be arranged in a predetermined position along the upper part of the shoe. In other words, the course of the tape on the shoe upper can be specified particularly precisely. By precisely specifying the course of the band, it is possible to specify exactly where on the upper part of the shoe the introduction of force from the circumferential, tensile band into the shoe and further onto the foot or lower leg takes place. Furthermore, the positioning element can be used to dampen the Inversion or supination movement required restraint force are evenly distributed so that local pressure points can be avoided.

In order to achieve a particularly precise positioning of the course of the stiff belt on the shoe upper and also to enable a movement or displacement of the stiff belt with little friction, a plurality of positioning elements and a plurality of tubular elements are provided according to a further preferred embodiment, the positioning elements and the tubular elements are preferably arranged alternately along the tension-resistant band and / or at least one tubular element is formed integrally with a positioning element or is fastened to a positioning element.

According to a further preferred embodiment, the damping element is arranged on the lateral side, the damping element preferably being at least partially integrated into the shoe upper. In this way, particularly effective damping of an inversion or supination movement can be achieved. In addition, the damping element can be arranged on the shoe or integrated into the shoe in a simple manner without significantly impairing the wearing comfort.

According to a particularly preferred further embodiment, the damping element is arranged in the shoe sole, the tension-resistant band preferably being guided in a sliding manner into the shoe sole by means of a deflection. As a result, the shoe can be constructed essentially unchanged in its visual appearance compared to a shoe without a damping arrangement. In addition, the dimensions of the damping element can be made larger than in the case of an arrangement on the lateral side, without impairing the external appearance or the wearing comfort due to pressure points. In particular, if the shoe has a plastic sole and / or rubber sole, the damping element can be produced with little manufacturing effort by simply embedding the damping element in the plastic or by overmolding the damping element in the shoe sole.

According to a further preferred embodiment, the shoe upper has a flexible molded part for positioning the tension-resistant band, which can preferably be integrated into a shaft of the shoe upper. The molded part preferably has a plurality of positioning elements and tubular elements, preferably arranged alternately in the longitudinal extension of the tension-resistant belt, in which the tension-resistant belt is slidably guided. The positioning elements are used primarily for the force-transmitting positioning of the tension-resistant band on the upper side of the shoe. The tubular elements provide preferred for the fact that the tensile stiff band can slide with very little friction in its longitudinal extension relative to the shoe during a movement. The retaining force required to dampen the inversion or supination movement can be evenly distributed by the molded part, so that local pressure points can be avoided. In addition, a simple production of the shoe is achieved, since the molded part can be preassembled and can then be inserted into the shoe in a simple manner as a finished molded part during the assembly of the shoe.

In order to achieve a particularly advantageous course of the tension-stiff ligament and thus a particularly effective introduction of the forces arising during inversion or supination, the tensile-stiff ligament according to a further preferred embodiment is arranged at least partially above a receiving area for receiving the medial ankle.

If, according to a further preferred embodiment, the tensile stiff band is arranged at least partially above a receiving area for receiving the lateral ankle, the retaining effect of the circumferential tensile stiff band can be further improved.

If the fastening of the second end of the tensile strap is adjustable according to a further preferred embodiment on the shoe upper, the shoe can be individually adapted for a variety of different foot, ankle and lower leg shapes, so that the best possible protection against injury for each wearer can be achieved due to an inversion or supination movement.

Preferably, a length of the tensile band between the first end and the attachment to the shoe upper can be changed, the tensile band preferably having at least one hook, an eye and / or a loop and / or at least one eye, a hook, on the shoe upper Adhesive area and / or a clamping unit is provided for clamping the tension-stiff tape.

According to a further preferred embodiment, an adjustment unit for adjusting the length of the tension-resistant band is arranged on the tension-resistant band, the tension-resistant band preferably forming a variable loop in the adjustment unit. In this way, the length of the tension-resistant band and consequently the damping and protective effect can be individually adapted essentially continuously in a particularly simple manner.

According to a further preferred embodiment, the damping element and / or the rigid band are at least partially integrated into the shoe, the damping element and / or the rigid band preferably at least partially under an outer one Surface or top layer of the shoe run. In this way, on the one hand, a particularly dimensionally stable positioning of the damping element and / or the tension-resistant band can be achieved, and on the other hand, the external appearance is changed only insignificantly by mechanically appearing components.

In a further preferred embodiment, the shoe has an upper, the rigid band running at least partially in the region of the upper, the rigid band preferably being at least partially integrated into the upper. In this way, a particularly advantageous and positionally stable arrangement of the tension-resistant strip can be achieved.

In a preferred development, the shaft can be designed in the form of a sock shaft. This ensures a high level of wearing comfort, and precise positioning of the course of the tensile strip can also be achieved.

According to a further preferred embodiment, a further band made of a tensile stiff material is arranged on a side of the damping element opposite the first end, the further band having a further end opposite the damping element with which the further band is fixed to the shoe, preferably to the shoe upper , connected is. As a result, the damping element can be integrated into the rigid band or an entire band can be formed from the rigid band, the damping element and the further band, the entire band being movably arranged along its longitudinal extension on the shoe and at the second end and the other End is attached to the shoe.

The damping element is preferably a fiber-shaped damping element.

A particularly effective damping or restraint of the movement via the ankle joint can be achieved if the rigid band and / or the damping element are oriented on the lateral side in such a way that the rigid band and / or the damping element at least partially with a plane defined by the shoe sole enclose an angle from 0 ° to 90 °, preferably from 30 ° to 70 °, particularly preferably from 50 ° to 60 ° and very particularly preferably 57 °.

A particularly effective damping or restraint of the movement via the ankle joint can also be achieved if the tensile stiff band is oriented in the area of the second end on the lateral side in such a way that the tensile stiff band is viewed from above on a plane defined by the shoe sole with a longitudinal axis or central longitudinal plane of the shoe at least partially encloses an angle from 0 ° to 90 °, preferably from 20 ° to 70 °, particularly preferably from 30 ° to 60 °.

According to a further preferred embodiment, the tensile band is arranged in such a way that in a plan view of a plane defined by the shoe sole with a linear extension of the tensile band at the first end and a linear extension of the tensile band at the second end, the linear extension of the first end and the linear extension of the second end intersect at a point on the outer edge of the shoe sole, preferably a point at a maximum distance from the longitudinal axis or central longitudinal plane of the shoe. As a result, an exact introduction of tensile force into the band as a result of a kinking at the point of the outer edge of the shoe sole can take place.

Detailed description of preferred exemplary embodiments

Preferred exemplary embodiments are described below with reference to the figures. Identical, similar or identically acting elements are provided with identical reference symbols in the different figures, and a repeated description of these elements is in some cases dispensed with in order to avoid redundancies.

In Figure 1 is schematically shown a perspective side view of a shoe 1 for dampening a foot movement via the ankle joint according to a first embodiment. The shoe 1 has a shoe sole 10 and an upper 11 connected to the shoe sole 10. A damping element 2 for damping a relative movement is arranged on a lateral side 12 of the shoe 1, the damping element 2 having a fixed element 20 rigidly connected to the upper part 11 of the shoe 1 and a relative movement element 21 movable relative to the fixed element 20. The relative movement element 21 can be pushed into and out of the fixed element 20 along a pull-out direction, the relative movement of the relative movement element 21 relative to the fixed element 20 being damped adaptively, in the present case speed-dependent and acceleration-dependent.

A tension-resistant band 3 is also arranged on the upper 11. The tensile stiff band 3 extends from a first end 31 from the lateral side 12 of the shoe 1 over a shoe heel area 14 and over a medial side 13 of the shoe back to the lateral side 12 to a second end 32, the tensile stiff band 3 with the first end 31 is fastened to the relative movement element 21 of the damping element 2 and is fastened to the shoe upper 11 with the second end 32.

The rigid band 3 is movably arranged between the first end 31 and the second end 32 on the shoe upper 11 along its longitudinal extension. In order to hold the tension-resistant band 3 on the pushing upper 11 in a fixed position, the tension-resistant band 3 according to this embodiment is positioned on the shoe upper 11 by means of a positioning element 5. The rigid band 3 can also slide in the area of the positioning element 5 relative to the positioning element 5 along its length. The positioning element 5 is arranged on a high shaft 15, which in the present case is in the form of a sock upper is formed, which extends from a one end 16 of the shoe upper 11 upwards.

Figure 2 shows schematically a top view of the shoe 1 from FIG Figure 1 . As the rigid band 3 runs from the lateral side 12 over the shoe heel area 14, the medial side 13 back to the lateral side 12, the rigid band 3 forms a loop, which pulls forces introduced into the ends 31, 32 on the lateral side 12 in the shoe heel area 14 as well as on the medial side 13 and partly also on the lateral side 12 into the shoe 1 and further into the lower leg 6 of a person wearing the shoe. In Figure 2 the tensile forces introduced into the first end 31 and second end 32 during an inversion or supination of the foot are indicated by the reference symbol F, and the line load transferred from the rigid band 3 to the lower leg 6 is indicated by the reference symbol L. The circumferential, tensile band 3 is therefore supported in the event of an inversion or supination of the foot in accordance with the line load distribution shown. The forces are transmitted essentially over the entire circumferential length on the medial side 13, on the shoe heel area 14 and also partially on the lateral side 12 via the shoe upper 11 to the person wearing the shoe 1.

Due to the aforementioned arrangement of the tension-resistant band 3 and the damping element 2, the shoe 1 can adaptively dampen an inversion or supination movement via the ankle joint.

Figure 3 shows schematically the shoe 1 from Figure 2 with an adjustment unit 33 for adjusting the length of the tension-resistant band 3. The tension-resistant band 3 is guided through an eyelet (not shown) of the adjustment unit 33 and accordingly forms a length-adjustable loop 34 in the adjustment unit 33.

Alternatively, the fastening of the second end 32 of the rigid band 3 on the shoe upper 11 can be adjustable in order to adjust the length of the tension-resistant band 3. For this purpose, the rigid tape 3 can have at least one hook, an eye and / or a loop and / or at least one eyelet, a hook, an adhesive area and / or a clamping unit for clamping the rigid tape can be provided on the upper 11.

Figure 4 shows schematically a perspective side view of a shoe 1 for dampening a foot movement via the ankle joint according to a further embodiment. The shoe 1 corresponds to that of the embodiment according to Figure 1 , wherein a tubular element 4 is arranged here on the positioning element 5, in which the rigid band 3 along its The longitudinal extension is slidably guided. the end Figure 5 a perspective side view of a shoe 1 for damping a foot movement via the ankle joint according to a further embodiment can be seen schematically. The shoe 1 off Figure 5 essentially corresponds to that from Figure 1 , wherein the damping element (not shown) and parts of the tensile band 3 are integrated into the shoe 1. The damping element and the integrated parts of the tension-resistant band 3 are arranged below a cover layer 110 of the shoe upper 11. As a result, the cushioning element and the integrated parts of the band 3 lie under an outer surface of the shoe upper.

Figure 6 shows schematically the shoe Figure 5 in a further perspective side view, the parts of the tension-resistant band 3 integrated under the cover layer 110 in the shoe upper 11 in the area of the first end 31 and the second end 32, as well as the damping element 2 being indicated by dashed lines.

In Figure 7 is schematically shown a perspective side view of a shoe 1 for dampening a foot movement via the ankle joint according to a further embodiment. The shoe 1 off Figure 7 essentially corresponds to that from Figure 1 wherein the end 16 does not divide the upper 11 into a sock shaft and a thicker, lower part, but the shoe 1 has an end 16 at the upper edge of the shaft 15; the cover layer 110 extends to the end 16 at the upper edge. The shoe 1 is therefore in the in Figure 5 embodiment shown designed as a boot.

In this embodiment, the rigid band 3 is arranged above a receiving area (not shown) for receiving the medial ankle and is arranged above a receiving area 17 for receiving the lateral ankle of the foot.

Figure 8 shows schematically a detailed view of a flexible molded part 7 which can be integrated into a shaft of a shoe. The molded part 7 has positioning elements 5 and tubular elements 4 arranged in an alternating manner in the longitudinal extension of the rigid strip 3, in which the rigid strip 3 is slidably guided. The positioning elements 5 are primarily used for the force-transmitting positioning of the tension-resistant band 3 on the upper side 11 of the shoe and for evenly distributing the retention force caused by the tension-resistant band 3 in the shoe 1 and further into the lower leg 6 or foot of the wearer. The tubular elements 4 ensure that the tension-resistant band 3 can slide with very little friction in its longitudinal extension relative to the shoe when it is moved. In order to also provide a low-friction guide on the positioning elements 5, the positioning elements 5 have further tubular elements 4. In order to enable low-friction sliding, the tubular elements 4 as well as the positioning elements 5 a plastic with a low coefficient of friction, in this case PTFE or alternatively POM.

Figure 9 shows schematically a perspective side view of a shoe 1 for dampening a foot movement via the ankle joint according to a further embodiment. The shoe 1 off Figure 9 corresponds essentially to the aforementioned embodiments, the damping element 3 being arranged in the shoe sole 10. The rigid band 3 is deflected into the shoe sole 10 by means of a deflection 30.

In Figure 10 the shoe 1 is shown schematically Figure 9 shown in a further perspective side view obliquely from below. As shown by the dashed lines, embedded in the cushioning element 2 within the shoe sole 10. In order to provide the lowest possible friction in the shoe sole 10, the rigid band 3 is surrounded by a tubular element 4 and is guided in it in a sliding manner. The tubular element 4 extends over the deflection 30 into the shoe upper 11 up to the end 16.

Figure 11 shows schematically a perspective side view of a shoe 1 for dampening a foot movement via the ankle joint according to a further embodiment. The shoe 1 has a sock 18 made of an elastic textile knitted fabric or, alternatively, a textile fabric, which essentially forms the upper 11 of the shoe. Separate cover layers 110 designed as patches are arranged on the sock 18. The lowermost, therefore most distally arranged cover layer 110 'is connected to a sole 10 which is formed in one piece with the lowermost cover layer 110 as a patch. The cover layers 110 and the sole 10 are made of a more rigid material than the sock 18.

The tensile stiff band 3 is attached with its second end 32 to the lowermost cover layer 110 ′ connected to the sole 10. The first end 31 is attached to a fibrous damping element 2, in which a pull-out body in fiber form is movably arranged in a pull-out container in tube form relative to the pull-out container. Alternatively, other preferably elongated damping elements can also be used. On the side of the damping element 2 opposite the first end 31 there is arranged a further band 35 made of a material with high tensile strength, which at its further end 36 is firmly connected to the shoe 1, in the present case attached to the cover layer 110 '. The damping element 2 is movably arranged on the shoe upper 11. Consequently, the rigid band 3, the damping element 2 and the further band 35 form an entire band, this entire band being movably arranged on the shoe 1 over its entire length along its longitudinal extension and only at the second end 32 and the other End 36 is attached to the shoe 1. In other words, the damping element 2 and the further band 35 are designed as part of the band 3.
