Description

  The present invention relates to adjustable shoe uppers and adjustable soles, and shoes comprising such shoe uppers and / or such soles.

  A shoe typically includes a shoe upper and a sole attached thereto. After purchasing the shoe, the width and length of the shoe upper and / or sole cannot be adjusted. However, it is often the case that the wearer notices that the shoes are not perfectly well matched after purchasing them and wearing them for some time. In addition, shoes are made on shoe molds, but the dimensions (e.g., width) of shoe molds have been determined according to average values from the population. Therefore, those whose feet do not correspond to their average value will always not get the perfect shoe that fits perfectly. Also, the shape and / or size of the foot can change over time. This is especially true for children whose shoe sizes change rapidly during the first few years of life.

  Further examples are sports enthusiasts who are dressed for foot and / or ankle support, eg for medical reasons. In this case, the shoe is not optimal because of the bandage, which may cause shoe rubbing. Still further examples are those with differently formed feet, for example, slightly different sized feet. Since the pair of left and right shoes are usually made on a mirror-symmetric shoe shape, at least one of both shoes will not optimally fit in this case.

  DE202010017958U1 relates to sports shoes, in particular soccer shoes, in which the entire shoe comprises two components-an inner section and an outer section.

  According to US 2014/0325871 (A1), a sole for a shoe is provided, including a midsole and an outer sole. The midsole includes a base body and a plurality of deformation elements. The outer sole includes a first outer sole region and a plurality of first outer sole elements, and a deformation load assigned to the first outer sole element by a pressure load on the first outer sole element. At least one of these deformations is provided.

  U.S. Pat. No. 7,546,698 (B2) and U.S. Pat. No. 7,770,307 (B2) are formed of at least a portion of a base layer and a suture section adjacent to the surface of the base layer. An article of footwear comprising a shoe upper is provided. The suture sections are arranged, for example, to provide structural elements that limit rotation in a direction corresponding to their longitudinal axis.

  U.S. Pat. No. 8,561,322 (B2) relates to a size adjustable sole. The sole includes a solid region and an adjustable region. The adjustable region can be deformed when the sole is heated to the melting temperature assigned to the adjustable region. The shape and size of the sole can be adjusted by deforming the adjustable region.

  [31] The shoe according to [30], wherein the sole is the sole according to any one of [1] to [21].

  According to a first aspect of the invention, the problem is a shoe upper for a shoe, in particular a sports shoe, which is fixed to (a.) The first layer and (b.) The first layer. And (c.) The second layer includes at least two regions separated from each other; (d.) The first layer includes at least two of the second layer; It is solved by a shoe upper with a higher elasticity than the second layer in the area not covered by the area.

  According to the present invention, the shoe upper includes a first layer and a second layer connected thereto. The elasticity of the first layer is higher than the elasticity of the second layer. Through this, the shoe upper can be optimally adapted to the shape of the wearer's foot due to the fact that the first layer bends. In order to allow the first layer to stretch, the less elastic second layer does not form a closed surface, but forms at least two regions that are separated from each other. The first layer is more elastic than the second layer, at least in areas not covered by these areas. Thus, at least two regions of the second layer form a gap for the underlying or overlying first layer. Depending on the shape of the foot, this gap widens somewhat so that the shoe upper can adapt to the shape of the foot.

  Since the second layer is less elastic than the first layer, the second layer can provide the necessary support for the foot, regardless of the flexibility and suitability of the shoe upper. Specifically, the second layer can provide stability to the shoe upper, particularly in places subject to stress, such as the heel and toe regions.

  The configuration according to the present invention and the relative elasticity of the first and second layers provides an adjustable and flexible shoe upper that can simultaneously provide the necessary support and stability to the foot.

  The elasticity of a material is, for example, its modulus of elasticity (also called modulus of tension, elasticity coefficient, modulus of elasticity, E-modulus, or Young's modulus). Can be described by The absolute value of the elastic modulus becomes larger as the tensile stress required to cause a specific elongation increases.

  The second layer can be at least partially disposed on the first layer. Thereby, the second layer may limit the elasticity of the first layer at systematically selected locations. Therefore, the second layer can define the elastic limit of the underlying first layer in the region where the first layer and the second layer overlap.

  The first layer can substantially define the shape of the shoe upper. That is, the shoe upper shape is provided by the first layer. This simplifies the shoe upper manufacturing process because no additional material is required beyond the second layer. For example, the first layer can be manufactured as a knitted fabric made in one piece on a flat knitting machine or a warp knitting machine.

  At least two regions of the second layer can be patches that are spaced apart from each other and disposed on the first layer. The patch can simply be cut or stamped from a suitable material and secured on the first layer.

  At least two regions of the second layer can be made of leather or plastic. These materials are relatively easy to process and provide a high degree of stability and support to the foot at the location of the shoe upper where those areas are located.

  At least two regions of the second layer can be stitched, glued, or welded onto the first layer. In this way, a simple but durable connection between the first layer and the second layer can be established.

  The first layer can be made of an elastic polyurethane material, an elastic polyurethane-coated substrate, or an elastic rubber-coated plastic. These materials have the ideal elasticity for the present invention and are strong and long lasting.

  The first layer can be formed as a substantially double layer. For example, the inner ply can be made of a lining material, such as a foam material. As a second ply, an elastic material can be added to the first ply. The second ply can be glued or welded to the first ply, for example. The first ply and the second ply can overlap at least partially.

  At least two regions of the second ply may be connected by at least one first connecting element. The connecting element can limit the relative placement of the two regions relative to each other, thereby defining the maximum extension of the shoe upper. As such, it can be prevented that the shoe upper stretches excessively and does not provide sufficient support and stability to the foot. For example, the connecting element can ensure a maximum distance between at least two regions of the second ply. The connecting element therefore prevents the gap between the two regions from becoming too large and the first ply from being stretched excessively. Thus, the connecting element is a limit on the elasticity of the shoe upper.

  The connecting element comprises a lower elasticity than the first ply. Thus, the elasticity of the shoe upper can be effectively limited.

  At least one connecting element can be made so that it can be disconnected. The elasticity of the shoe upper in the area of the connecting element to be cut if the foot requires more space (for example, a shoe for a child, bandaged foot, or asymmetrically shaped foot) Can be enhanced by systematic disconnection of the connecting elements. Thus, the shoe upper can be systematically adapted to the shape and / or size of the foot. Such adaptation can be done by the respective shoe owner even after purchase. No special tools are required for that purpose.

  At least one connecting element may be removably connected to at least two regions of the second ply. For example, the connecting element can be attached to at least two regions of the second ply by means of a velcro fastener or a snap fastener. Also, the elasticity of the shoe upper can be adapted in this way. This action is reversible because the connecting element can be attached to the shoe upper again. If the wearer can remove the bandage, for example due to medical recovery, the elasticity of the shoe upper can be adapted according to the narrowed space required for the foot by reattaching the connecting element.

  The maximum distance between at least two regions of the second layer may increase when at least one connecting element is cut or removed. In this way, as already explained, the elasticity of the shoe upper can be systematically improved.

  At least one connecting element can be replaced by another connecting element having a different length. Thereby, the maximum elasticity of the shoe upper can be easily adjusted. For example, a child's foot can replace a connecting element with a longer connecting element when the child's foot reaches a specific shoe size.

  The at least two regions of the second layer can be connected to each other by at least one second connection element. Thus, the second connection element may have a different length than the first connection element. Thereby, the elasticity of the shoe upper can be improved when the shorter connecting element (eg the first connecting element) is cut or removed.

  The second connection element can be arranged on the first connection element. For example, a shorter first connecting element may be arranged on a longer second connecting element. By cutting or removing the first connecting element, the maximum elasticity of the shoe upper is improved.

  The second connection element can be arranged in addition to the first connection element. The second connection element may be a connection element having the same length as the first connection element. Alternatively, the second connecting element may have another length in order to be able to adjust the maximum elasticity of the shoe upper as already described.

  The first connecting element and / or the second connecting element can be made of a material that is inelastic or slightly elastic. In any case, the elasticity of the first and / or second connecting element is lower than the elasticity of the first layer. The first and / or second connecting element can be made, for example, from a textile material. The fibrous material can be, for example, a knitted, braided and / or woven material, and / or a non-woven fabric.

  A further aspect of the invention relates to a shoe, in particular a sports shoe, comprising (a.) A shoe upper as described above and (b.) A sole attached to the shoe upper.

  A still further aspect of the invention is a sole, in particular a sole for sports shoes, wherein (a.) A first layer and (b.) A second layer fixedly connected to the first layer. (C.) The second layer includes at least two regions separated from each other, and (d.) The first layer is not covered by at least two regions of the second layer. The sole relates to a sole having higher elasticity than the second layer in one region.

  This aspect of the invention also makes it possible to obtain a shoe that fits the foot in an optimal manner. That is, according to the present invention, the sole includes a first layer and a second layer connected to the first layer. The elasticity of the first layer is higher than the elasticity of the second layer. Through this, the sole can be optimally adapted to the sole of the wearer's foot as the first layer flexes. In order to allow the first layer to stretch, the less elastic second layer does not form a closed surface, but forms at least two regions that are separated from each other. The first layer is more elastic than the second layer, at least in areas not covered by these areas. Thus, at least two regions of the second layer form a gap for the underlying or overlying first layer. Depending on the shape and load of the sole of the foot, the gap widens somewhat to fit the sole of the foot.

  Due to the fact that the second layer is less elastic than the first layer, the second layer can provide the necessary support for the foot, regardless of the flexibility and conformity of the sole. In particular, the second layer can provide stability in the sole and particularly in places subject to stress, such as the heel and toe regions. Further, the second layer can be contoured and wear resistant to contact with the ground.

  The construction according to the invention and the relative elasticity of the first and second layers can not only provide the necessary support and stability for the sole of the foot, but can also provide traction and wear resistance simultaneously. An adjustable and flexible sole is obtained.

  The inner sole may include at least one first region with higher elasticity than the second region of the inner sole. In this way, the inner sole is also correspondingly adapted to the shape and load of the foot. The arrangement of the at least one first region with higher elasticity of the inner sole can be adapted to the arrangement of the second layer on the first layer. The inner sole may preferably include a region having higher elasticity in a region where the second layer does not overlap the first layer.

  The second layer can be at least partially disposed on the first layer. Thus, the second layer may limit the elasticity of the first layer at systematically selected locations. As such, the second layer may define the elastic limit of the underlying first layer in the region where the first layer and the second layer overlap.

  The first layer can substantially define the shape of the sole. That is, the shape of the sole is defined by the first layer. This simplifies the manufacturing process of the sole because no additional material is required other than the second layer. For example, the first layer can be manufactured integrally by a casting method.

  The second layer can be injection molded into the first layer. By doing so, a fixed and permanent connection between both layers can be provided.

  The first layer may be made of a TPU having a Shore hardness of 60-100A, 70-90A, or 78-82A. The second layer can be made of a polyamide having a Shore hardness of 90-100A or 94-96A, such as PA6, PA11, or PA12, and / or TPU.

  The sole may further include an inner sole. The inner sole can function as an insole. The inner sole provides a feeling that the shoe is comfortable to wear and may further comprise additional functions, such as breathability and / or moisture absorption.

  The region of higher elasticity of the inner sole can at least partially overlap the region of higher elasticity of the first layer of the sole. Thus, in selected areas (eg, in the heel and / or toe areas), the entire sole can optimally conform to the shape of the soles of the wearer and / or depending on the load Can be stretched.

  A still further aspect of the invention relates to a shoe, in particular a sports shoe, comprising (a.) A sole as described above, and (b.) A shoe upper attached to the sole.

  The shoe upper may be a shoe upper as described above.

  Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 6 is a side view of a further exemplary embodiment of a shoe having a shoe upper according to the present invention. FIG. 6 is a plan view of a further exemplary embodiment of a shoe having a shoe upper according to the present invention. FIG. 6 is an inside view of a further exemplary embodiment of a shoe having a shoe upper according to the present invention. FIG. 6 is an illustration of an exemplary embodiment of a shoe having a sole according to a further aspect of the present invention.

  Hereinafter, exemplary embodiments and modifications of the present invention will be described in more detail.

  FIG. 1 shows a schematic view of a shoe 11 comprising a shoe upper 12 according to the invention. The shoe 11 shown in FIG. 1 is a sports shoe, for example, a soccer shoe. The present invention can be applied to all sports shoes such as rugby shoes, soccer shoes, basketball shoes, tennis shoes, golf shoes, running shoes, and the like. The present invention is not limited to sports shoes, but can also be applied to shoes that are usually worn or worn on a ceremonial occasion.

  The shoe upper 12 includes a first layer 13. In the exemplary embodiment of FIG. 1, the first layer 13 substantially defines the shape of the shoe upper 12. That is, the shoe 11 can be worn without the second layer 14 described later. However, in this case, the shoe upper 12 should be bent excessively at a specific point where the bending should occur. In general, it is sufficient that the first layer 13 is disposed in a specific region of the shoe upper 12. That is, the first layer need not extend throughout the shoe upper 12. For example, the first layer 13 may be disposed only in the toe region, the heel region, the upper region, or a combination thereof. In general, the first layer 13 is disposed at a position where the shoe upper 12 should be stretchable so that the shoe upper 12 can conform to the shape of the foot.

  In the exemplary embodiment of FIG. 1, the first layer 13 also includes two different types of regions. A first region is indicated by reference numeral 13 a and extends across the front foot region along the lower region of the side surface of the shoe upper 12 to the rear region of the shoe upper 12. Further, the first layer 13 includes a further region 13 b in the toe region of the shoe upper 12, a region 13 c in the front region, and a region 13 d in the upper region of the shoe upper 12. The material used for region 13a may be different from the material used for regions 13b, 13c, and 13d. Specifically, the elasticity of these materials may be different.

  It is also possible to form the first layer by substantially overlapping two sheets. For example, the inner ply can be made of a lining material, such as a foam material. As a second ply, an elastic material can be added to the first ply. The second ply can be glued or welded onto the first ply, for example. The first ply and the second ply can overlap at least partially. For example, as an alternative to the exemplary embodiment shown in FIG. 1, the inner ply may extend substantially throughout the shoe upper and is visible in the intersection region indicated by reference numeral 13a. It may be. On the inner ply, the region of the second ply indicated by reference numerals 13a, 13b, 13c and 13d can be glued or welded. The elasticity of the first ply may be different from the elasticity of the second ply.

  The arrangement and shape of the regions 13a, 13b, 13c, and 13d in FIG. 1 are understood only by way of example and may vary depending on the application of the shoe 11 (eg, sports). Further, the first layer 13 may be made of one material as a whole without including such a region.

  The first layer 13 is an elastic material. Possible materials are, for example, polyurethane or rubber-coated plastic.

  The shoe upper 12 also includes a second layer 14 fixedly connected to the first layer 13, the second layer 14 including at least two regions separated from each other. In FIG. 1, two such regions are exemplarily indicated by reference numerals 14a and 14b. Regions 14a and 14b are patches placed on the first layer 13 at a distance from each other. Further, FIG. 1 is an exploded view. That is, the second layer 14 is shown spaced from the first layer 13 for illustrative reasons. In general, however, the second layer 14 is fixedly connected to the first layer 13 by, for example, stitching, bonding or welding.

  At least two regions of second layer 14 (exemplarily shown in FIG. 1 by reference numbers 14a and 14b) are spaced apart. That is, the regions 14a and 14b are disposed on the first layer 13 so as to be separated from each other. At least two regions 14a and 14b can be made of leather or plastic.

  According to the invention, the first layer 13 has a higher elasticity than the second layer 14 in at least one region that is not covered by at least two regions of the second layer. In the exemplary embodiment of FIG. 1, the region 13 a of the first layer 13 is not covered by the second layer 14. The elasticity of the region 13a is higher than the elasticity of the second layer 14, specifically the elasticity in at least two regions 14a and 14b.

  The elasticity of a material can be described, for example, by its elastic modulus (also called tensile modulus, elasticity coefficient, elastic modulus, E-modulus, or Young's modulus). The absolute value of the elastic modulus becomes larger as the tension required to cause a specific extension is larger.

  Due to the fact that the second layer 14 has a lower elasticity than the first layer 13 and is fixedly connected to the first layer 13, the second layer 14 and the first layer 13 In the region where the second layer 14 overlaps, the elastic limit of the first layer 13 located below is defined.

  In the exemplary embodiment of FIG. 1, the second layer 14 completely overlaps the underlying first layer 13. That is, there is no region where both layers do not overlap. Within the scope of the present invention, it is also conceivable that the first layer 13 and the second layer 14 partially overlap. Also, in the exemplary embodiment of FIG. 1, the second layer 14 is disposed on the first layer 13. The reverse arrangement is also possible. That is, the second layer 14 may be disposed under the first layer 13.

  In the exemplary embodiment of FIG. 1, at least two regions 14a and 14b of the second layer 14 are connected to each other by an optional first connecting element. Such a first connection element is exemplarily shown in FIG. 1 by reference numeral 15a. The connecting element 15a ensures a maximum distance between at least two regions 14a and 14b of the second layer 14. Here, the connecting element 15 a may have a lower elasticity than the first layer 13. That is, the connecting element 15a limits the relative movement of both regions 15a and 15b relative to each other that can occur due to the higher elasticity of the underlying first layer 13.

  The first connecting element 15a can be made, for example, from a non-woven material. Alternatively, the first connecting element 15a may be a knitted, braided and / or woven material. In the first example of FIG. 1, the first connecting element 15a has a tape-like shape, but it is also conceivable that the first connecting element 15a has a circular cross section and is, for example, a thread or a yarn.

  The first connecting element 15a may be made so that it can be disconnected. In the first example of FIG. 1, the first connecting element 15a can be cut, for example by scissors. It is also conceivable that the first connection element 15a is removably connected to at least two regions 14a and 14b. For example, the first connecting element 15a and at least one of the two regions 14a and 14b can comprise a snap fastener or a velcro fastener so that the connecting element can be removed from this region. It is also conceivable that the other areas also comprise snap fasteners or velcro fasteners so that the connecting element 15a can be completely removed from the shoe upper 12.

  In general, when the first connecting element 15a is cut or removed, the connecting element is in contact with each other of the two regions 14a and 14b, which can occur due to the lower elasticity of the underlying first layer 13. Since it no longer limits the relative movement, the maximum distance between the at least two regions 14a and 14b of the second layer is increased. That is, when the connecting element 15a in the exemplary embodiment of FIG. 1 is cut or removed, the elasticity of the shoe upper 12 is improved in this lateral region where the connecting element 15a is located. Then, the shoe upper 12 can accept a foot having a wider width.

  It is also conceivable that the first connection element 15a can be replaced by another connection element having a different length. In other words, the maximum elasticity of the shoe upper can be adjusted in the region of the connecting element 15a. The shorter connecting element correspondingly limits the elasticity of the shoe upper, while the longer connecting element allows a wider spacing between the second layer regions 14a and 14b.

  As shown in the exemplary embodiment of FIG. 1, the regions 14a and 14b of the second layer 14 are connected to each other by an optional second connecting element 15b. The second connection element 15b is arranged in addition to the first element 15a. However, it is also conceivable that the second connection element 15b is arranged on the first connection element. The second connection element 15b can have a length different from that of the first connection element. For example, the length of the second connection element 15b may be longer than the length of the first connection element 15a. As already explained, if the first element 15a is removed or cut, the maximum distance between the two regions 14a and 14b of the second layer 14 is now the longer second connection element 15b. The elasticity of the shoe upper is improved in the region of the connecting element 15a.

  The shoe 11 shown in FIG. 1 also includes a sole 16 in addition to the shoe upper 12 already described. The sole 16 is connected to the shoe upper 12 by, for example, sewing, bonding, or welding. Alternatively, the sole 16 can be injection molded directly onto the shoe upper 12. The sole 16 is an ordinary sole, for example, a sole made from ethylene vinyl acetate (TPU), thermoplastic polyurethane (TPU), cured rubber, or expanded polyurethane (eTPU). obtain. Alternatively, the sole 16 may be a sole according to another aspect of the present invention, described in more detail with reference to FIG.

  2A, 2B, and 2C show a further exemplary embodiment of a shoe 11 having a shoe upper 12 according to the present invention. This shoe is a soccer shoe and comprises, in addition to the shoe upper 12 already described with reference to FIG. 1, a sole 16 containing studs, three of which are exemplarily indicated by reference numeral 21. . Referring to the shoe upper 12, the shoe upper 12 described with reference to FIG. 1 is effective. Unlike the shoe upper 12 according to FIG. 1, the shoe upper according to FIGS. 2A, 2B and 2C comprises an additional connecting element in each of the rear foot region and the heel region, two of which are illustrated by reference numerals 15c and 15d. Has been shown. In addition, the shoe upper 12 according to FIGS. 2A, 2B and 2C comprises a greater number of connecting elements 15a, 15b, 15c, 15d overall, thereby further improving the suitability of the shoe upper 12.

  3A, 3B, and 3C illustrate an exemplary embodiment of the present invention that is an alternative to the illustration of FIGS. 2A, 2B, and 2C. The shoe 11 shown in FIGS. 3A, 3B, and 3C also includes a shoe upper 12 according to the present invention that has the same features as the shoe 11 shown in FIGS. 2A, 2B, and 2C. However, unlike the exemplary embodiments of FIGS. 2A, 2B, and 2C, the shoe 11 shown in FIGS. 3A, 3B, and 3C does not include a connecting element between the regions of the second layer. For example, unlike the exemplary embodiments of FIGS. 3A, 3B, and 3C, no connecting element is disposed between regions 14a and 14b. Due to the fact that the shoe 11 shown in FIGS. 3A, 3B and 3C does not comprise any connecting elements, the elasticity of the first layer 13 is essentially the same as in FIG. Lower than 2B and 2C exemplary embodiments.

  FIG. 4 illustrates an exemplary embodiment of a shoe 11 having a sole 42 according to a further aspect of the present invention. The shoe 41 shown in FIG. 4 is a soccer shoe. However, the sole 42 shown in FIG. 4 can be applied to any sports shoes such as rugby shoes, soccer shoes, basketball shoes, tennis shoes, golf shoes, running shoes, and the like. The present invention is not limited to sports shoes, but can also be applied to shoes that are usually worn or shoes worn at ceremonial occasions.

  The sole 42 includes a first layer 43. Layer 43 may be made from TPU 80A, for example. The sole 42 further includes a second layer 44 fixedly connected to the first layer 43. The second layer 44 includes a first section 45 made from PA 12 in the midfoot region. In addition, the first layer includes an anterior foot section 46a and a heel section 46b made from TPU 95A. This arrangement of the sections 45, 46a and 46b of the second layer 44 allows for a flexible and telescopic outer sole. However, the arrangement of sections 45, 46a, and 46b may change radically. Similarly, other materials may be used. The two layers 43 and 44 can be connected to each other by gluing or welding. Alternatively, the first layer 43 may be injection molded to the second layer 44 and vice versa.

  The second layer 44 includes at least two regions separated from each other, two of which are exemplarily shown in FIG. 4 by reference numerals 47a and 47b. The two regions 47a and 47b are separated from each other so that the first layer 43 is visible between the regions 47a and 47b of the second layer 44.

  According to the present invention, the first layer 43 has a higher elasticity than the second layer 44 in at least one region that is not covered by the at least two regions 47 a and 47 b of the second layer 44. In the exemplary embodiment of FIG. 4, the cruciform area of the first layer 43 is not covered by the second layer 44. In this region, the elasticity of the first layer 43 is higher than the elasticity of the second layer 44, specifically in the at least two regions 47a and 47b.

  In the exemplary embodiment of FIG. 4, the second layer 44 and the underlying first layer 43 are not completely covered. For example, the second layer 44 extends to the edge of the sole 42, but the first layer 43 does not extend that way. However, in the scope of the present invention, it is conceivable that the first layer 43 and the second layer 44 are completely covered, that is, there is no region where the two layers do not cover each other. In the embodiment of FIG. 4, the second layer 44 is disposed on the first layer 43. The reverse arrangement is also possible. That is, the second layer 44 may be disposed under the first layer 43.

  Due to the fact that the second layer 44 has a lower elasticity than the first layer 43 and is fixedly connected to the first layer 43, the second layer 44 is connected to the first layer 43. In the region where the second layer 44 overlaps, the elastic limit of the underlying first layer 43 is determined.

  In the exemplary embodiment of FIG. 4, the first layer 43 substantially defines the shape of the sole 42. That is, the shoe 41 can be worn without the second layer 44. In this case, however, the sole should bend excessively at a particular location. In general, it is sufficient that the first layer 43 is disposed in a specific region of the sole 42. That is, the first layer 43 need not extend over the entire sole 42. For example, the first layer 43 may be disposed only in the toe region, the heel region, the midfoot region, or a combination thereof. In general, the first layer 43 is positioned where the sole 42 should be stretchable so that the sole 42 can adapt to the shape and load of the soles of the foot while the shoe 41 is worn.

  Optionally, the sole 42 also includes an inner sole (not shown in FIG. 4). The sole may include a region that has a higher elasticity than other regions. The region of higher elasticity of the inner sole can at least partially overlap the region of higher elasticity of the first layer 43 of the sole 42. Thus, in selected areas (eg, in the heel and / or toe areas), the complete sole 42 can conform to the shape of the soles of the wearer and / or stretch according to the load. Can do.

  The shoe 41 shown in FIG. 4 also includes a shoe upper 48 that can be connected to the sole 42 by, for example, stitching, gluing, or welding. The sole 42 may be injection molded on the shoe upper 48. The shoe upper 48 may be a shoe upper as used in ordinary soccer shoes. Alternatively, the shoe upper 48 may be a shoe upper 12 according to the present invention, as already described with reference to FIGS. 1, 2A, 2B, 2C, 3A, 3B, and 3C.

  Within the scope of the present invention, the exemplary embodiments may be combined with each other to obtain further exemplary embodiments not explicitly described herein. For example, to obtain a new exemplary embodiment according to the present invention not explicitly described herein, certain features of one exemplary embodiment may be Can be combined with features.
