Abstract
Description
[Technical Field]
[0001] The present invention relates to a shoe comprising a shoe upper, an outsole and a stabilizing element. Furthermore, the present invention relates to at least one containment element within the shoe upper, a respective shoe upper and a method for manufacturing a shoe comprising said shoe upper. [Background technology]
[0002] When designing shoes, there is often a compromise between comfort, functionality, and safety. For example, a soccer shoe may provide excellent comfort due to its significant cushioning. However, the same soccer shoe may have functional deficiencies, such as limited feel for the ball, and safety deficiencies, such as insufficient ankle stabilization, due to its significant cushioning.
[0003] Nevertheless, the basic objective is to improve the comfort as well as the functionality and safety of shoes. Particularly for sports and outdoor activities, it is essential to ensure that shoes are comfortable to wear, have a low risk of injury, and fulfill the functions intended for the shoes. In this direction, the present invention aims to solve the first and second problems.
[0004] The first problem addressed by the present invention is the design of a stabilizing element for ankle stabilization. Various types of shoes require ankle stabilization to prevent ankle injuries and / or avoid ligament injuries. For example, when a soccer player shoots while standing on a soft and / or uneven surface, there is a high risk of ankle sprain, which can lead to injury. Therefore, stabilizing elements are sometimes applied to shoes, especially soccer shoes. However, stabilizing elements known in the prior art have several drawbacks. Existing stabilizing elements do not provide sufficient stabilization and / or are so uncomfortable that they affect leg health.
[0005] A first group of existing stabilizing elements surround the heel area and extend from the shoe outsole toward the medial and lateral ankle regions and toward the Achilles region, whereby such stabilizing elements extend from the lateral side of the shoe to the medial side of the shoe and at least partially surround the Achilles region, particularly the Achilles tendon insertion.
[0006] These stabilizing elements, formed around the heel area, provide the wearer with good ankle stability because they hold the heel tight. However, they exert pressure on the Achilles region, particularly at the Achilles tendon insertion, which is uncomfortable for the wearer, especially when running. Furthermore, this pressure on the Achilles region, particularly at the Achilles tendon insertion, can lead to irritation or even inflammation of the Achilles tendon.
[0007] The second group of existing stabilizing elements extends from the outsole of the shoe toward the medial or lateral ankle region, so that they do not extend from the lateral side of the shoe to the medial side of the shoe and therefore do not encompass the Achilles tendon region. Instead, a first stabilizing element is provided on the lateral side of the shoe and a second stabilizing element is provided on the medial side of the shoe.
[0008] Therefore, such a stabilizing element may avoid applying pressure to the Achilles region, especially the Achilles tendon insertion. Therefore, improved comfort may be provided. Furthermore, irritation or even inflammation of the Achilles tendon may be avoided. However, the existing stabilizing elements of the second group do not fasten tightly in the heel area, thereby providing less stability to the wearer.
[0009] Therefore, a primary objective underlying the present invention is to provide a shoe with stabilizing elements that maximize stability while minimizing pressure on the Achilles region, particularly the Achilles tendon insertion.
[0010] The second problem addressed by the present invention refers to the need to keep the wearer's foot secured within the shoe, preferably in a comfortable manner.
[0011] Generally, laces are known to secure a wearer's foot in a shoe. Furthermore, the use of stretchable elements and hook-and-loop fasteners is common for securing a wearer's foot in a shoe. However, in some cases, additional means for securing the leg in a shoe are additionally desirable. For example, when particularly good retention inside the shoe is required. Furthermore, in some cases, it may be necessary for the shoe to be laceless. One reason for this may be to provide a soccer shoe that allows a particularly good feel for the ball in the top midfoot area. Another reason is that tight laces are often felt uncomfortable.
[0012] Therefore, a second object underlying the present invention is to provide a means for improving the fixation of the wearer's foot within the shoe. Summary of the Invention
[0013] The first object underlying the present invention is at least partially achieved by the teachings of the independent claims, in particular by the first aspect of the present invention. Furthermore, the first object underlying the present invention is at least partially achieved by the second aspect of the present invention. Furthermore, the first object underlying the present invention is at least partially achieved by the third aspect of the present invention. Furthermore, the second object underlying the present invention is at least partially achieved by the fourth aspect of the present invention.
[0014] A first aspect of the present invention according to a first alternative embodiment relates to a shoe comprising a shoe upper, an outsole, and a stabilizing element. The stabilizing element extends from the outsole upward toward an entry opening of the shoe upper and rearward toward a heel region of the shoe. Optionally, the stabilizing element extends rearward into the heel region of the shoe. The stabilizing element further comprises an outer layer. The stabilizing element further extends along the exterior of the shoe upper, with a portion of the exterior of the shoe upper not covered by the stabilizing element, the portion being located between the stabilizing element and the outsole. The portion transitions continuously into a further portion of the exterior of the shoe upper not covered by the stabilizing element, whereby the further portion extends into a portion of the shoe upper configured to receive an Achilles tendon and / or Achilles tendon insertion. The outer layer of the stabilizing element is integrally molded with the outsole of the shoe.
[0015] In this regard, "integrally molded" may refer to an aspect in which no material boundary can be discerned between the outer layer and the outsole. Specifically, the outer layer and the outsole may be integrally formed by injection molding, direct casting, and / or foaming. Furthermore, the outer layer and the outsole may comprise a polymer material. Specifically, the outer layer and the outsole may comprise polyamide, polyurethane, and / or rubber. By integrally molding the outer layer with the outsole, the outer layer can be given a higher pre-tensioning force relative to the inner layer. This allows for greater pressure to be applied to the heel area of the wearer. Furthermore, the number of required work steps may be reduced.
[0016] The portion of the exterior of the shoe upper that is not covered by the stabilizing element and is located between the stabilizing element and the outsole may be at least partially bounded by an axis extending substantially perpendicularly from the outsole to the stabilizing element. More specifically, the axis may extend substantially perpendicularly from the plane of the flared edge of the shoe outsole to the most posterior point of the stabilizing element. The portion not covered by the stabilizing element at least partially avoids uncomfortable pressure on the Achilles region. In particular, the portion may prevent the stabilizing element from exerting pressure on the insertion of the Achilles tendon. Thus, shoe comfort may be improved and / or irritation of the Achilles tendon may be avoided. It is understood that additional portions of the shoe upper other than the portion of the exterior of the shoe upper that is located between the stabilizing element and the outsole may also not be covered by the stabilizing element.
[0017] The aforementioned additional portion additionally prevents uncomfortable pressure on the Achilles tendon area. In particular, the additional portion may prevent the stabilizing element from exerting pressure on the insertion of the Achilles tendon. Furthermore, the flexibility of the shoe upper may not be hindered by the stabilizing element in the Achilles area and / or at the insertion of the Achilles tendon. Therefore, the comfort of the shoe may be improved and / or irritation of the Achilles tendon may be avoided. The additional portion preferably extends from the lateral side of the shoe to the medial side of the shoe. This may further emphasize the above-mentioned advantages.
[0018] It will further be understood that the outer layer of the stabilizing element may be directly attached to the exterior of the shoe upper. By way of example, the outer layer of the stabilizing element may be attached to the exterior of the shoe upper by stitching, heat welding, and / or adhesive bonding. However, the outer layer of the stabilizing element may be in contact with the exterior of the shoe upper without being additionally attached to the exterior of the shoe upper. It will also be understood that the outer layer described above may be more generally referred to as a "layer." Nevertheless, the term "outer layer" is helpful in view of further features according to the present invention described below.
[0019] Furthermore, the stabilizing element of the shoe according to the first alternative of the first aspect of the present invention may include an inner layer. It is understood that the inner layer may be disposed between the outer layer and the exterior of the shoe upper. The inner layer may be used to provide additional support and achieve separation of functions within the stabilizing element. By way of example, the inner layer may provide support to the wearer's foot, while the outer layer serves to fasten the inner layer toward the wearer's foot. This may reduce the amount of material required for the stabilizing element, as the inner and outer layers are optimized for the specific functions they each perform.
[0020] Furthermore, the rearward side edge of the lower portion of the stabilizing element may extend upward from the outsole toward the foot opening of the shoe upper and rearward toward the heel region of the shoe, with the angle between the rearward side edge of the lower portion of the stabilizing element and the flared plane of the outsole preferably being 10° to 90°, more preferably 15° to 60°, even more preferably 20° to 50°, and most preferably 30° to 40°. The rearward side edge of the lower portion may at least partially limit the stabilizing element in the rearward direction. Furthermore, the stabilizing element may be at least partially limited in the rearward direction by the rearmost edge of the upper portion of the stabilizing element, which may be offset from the rearmost line of the upper extending upward from the outsole toward the foot opening. The rearwardmost edge of the upper portion may be positioned upward from the rearward side edge of the lower portion. The stabilizing element may be completely limited in the rearward direction by the rearwardmost edge of the upper portion and / or the rearward side edge of the lower portion. From the above, it will be understood that the above-mentioned areas of the exterior of the shoe upper that are not covered by the stabilizing element and are located between the stabilizing element and the outsole may alternatively be described.
[0021] Furthermore, the first aspect of the present invention according to a second alternative embodiment refers to a shoe comprising a shoe upper, an outsole, and a stabilizing element. The stabilizing element extends upward from the outsole toward an entry opening of the shoe upper and rearward toward a heel region of the shoe. Optionally, the stabilizing element extends rearward into the heel region of the shoe. Furthermore, the stabilizing element comprises an inner layer and an outer layer. Furthermore, the inner layer and the outer layer are made of different materials. The stabilizing element extends along the exterior of the shoe upper.
[0022] Different materials allow for the separation of functions. The inner layer may be made of a material with higher stiffness and / or strength than the outer layer. For example, the inner layer may include a fiber-reinforced polymer. Furthermore, the outer layer may be made of a material with higher elasticity or stiffness than the inner layer. For example, the outer layer may include a polyamide material. Thus, the inner layer may provide support, while the outer layer may fasten the inner layer to the shoe upper. Thus, the stabilizing element may be fastened to the wearer's heel and / or ankle, thereby improving stability. Furthermore, the weight of the stabilizing element may be reduced through the use of distinct materials. For example, an inner layer including a fiber-reinforced polymer may have a reduced thickness due to its higher tensile strength. Furthermore, the inner layer may be adapted to the characteristics of the wearer's foot, while the outer layer may remain unchanged. Therefore, the separation of functions within the stabilizing element through the use of different materials may reduce the effort required for modification. The inner layer and / or outer layer may include polymers such as polyamide, polyurethane, and / or rubber. In particular, the inner and / or outer layers may include ethylene vinyl acetate (EVA), polyamide 11 (PA11), and / or polyamide 12 (PA12). Additionally, the inner and / or outer layers may include a thermoplastic elastomer (TPE), such as polyether block amide (PEBA) and / or thermoplastic polyurethane (TPU). Additionally, the inner and / or outer layers may include a synthetic material, a natural material, and / or a metal.
[0023] The inner and outer layers of the shoe according to the first alternative may consist of different materials, and in this regard the configurations and / or advantages of the previous paragraph may be considered.
[0024] A shoe according to a second alternative embodiment may define a portion of the exterior of the shoe upper that is not covered by the stabilizing element, the portion being located between the stabilizing element and the outsole. The portion may be at least partially bounded by an axis extending substantially perpendicularly from the outsole to the stabilizing element. More specifically, the axis may extend substantially perpendicularly from the plane of the flared edge of the shoe outsole to the rearmost point of the stabilizing element. It will be understood that the axis may be a virtual axis and may serve to define the portion. The portion may avoid uncomfortable pressure on the Achilles region. In particular, the portion may prevent the stabilizing element from exerting pressure on the insertion of the Achilles tendon. This may improve shoe comfort and / or avoid irritation of the Achilles tendon. It will be understood that additional portions of the shoe upper, other than the portion of the exterior of the shoe upper that is located between the stabilizing element and the outsole, may also not be covered by the stabilizing element.
[0025] Furthermore, the rearward side edge of the lower portion of the stabilizing element may extend upward from the outsole toward the foot opening of the shoe upper and rearward toward the heel region of the shoe, with the angle between the rearward side edge of the lower portion of the stabilizing element and the flared plane of the outsole preferably being 10° to 90°, more preferably 15° to 60°, even more preferably 20° to 50°, and most preferably 30° to 40°. The rearward side edge of the lower portion may at least partially limit the stabilizing element in the rearward direction. Furthermore, the stabilizing element may be at least partially limited in the rearward direction by the rearmost edge of the upper portion of the stabilizing element, which may be offset from the rearmost line of the upper extending upward from the outsole toward the foot opening. The rearwardmost edge of the upper portion may be positioned upward from the rearward side edge of the lower portion. The stabilizing element may be completely limited in the rearward direction by the rearwardmost edge of the upper portion and / or the rearward side edge of the lower portion. From the above, it will be understood that the above-mentioned areas of the exterior of the shoe upper that are not covered by the stabilizing element and are located between the stabilizing element and the outsole may alternatively be described.
[0026] It will be understood that the following is directed to a first alternative of the first aspect of the present invention and a second alternative of the first aspect of the present invention. Furthermore, according to the present invention, the term "rear" in relation to a shoe refers to a direction from the tip of the shoe toward the Achilles region of the shoe. Thus, the "rearmost" point of a shoe element is the point that has the greatest distance from the tip of the shoe. Furthermore, according to the present invention, the term "upward" refers to a direction from the outsole toward the shoe upper.
[0027] The shoe according to the invention may be a sports shoe, a day shoe, a casual shoe, and / or a work shoe. Furthermore, the shoe may be a soccer shoe, a running shoe, a mountaineering shoe, a climbing boot, a ski boot, a cross-country ski boot, and / or a basketball shoe. The above examples are not conclusive.
[0028] The shoe upper may comprise a polymeric material and / or a natural material such as leather and / or natural fibers. Furthermore, the shoe upper may comprise a woven material, a knitted material, a material with unidirectional fibers, and / or a material without fibers. Preferably, the material of the main portion of the shoe upper has a lower stiffness than the material of the inner and / or outer layers of the stabilizing element.
[0029] The stabilizing element may serve to fixate the wearer's heel within the shoe. In particular, the stabilizing element may press the heel toward the sole of the shoe. This may primarily push the calcaneus toward the sole of the shoe, preferably without applying load to the Achilles region, particularly the Achilles tendon insertion. By fixing the wearer's heel within the shoe, instability due to heel slippage within the shoe may be avoided. Thus, the stabilizing element may serve to at least indirectly stabilize the wearer's ankle. Furthermore, by at least indirectly stabilizing the wearer's ankle, ankle sprains may be avoided. The term "ankle" in the present invention may also be referred to as the ankle joint.
[0030] The stabilizing element may be in contact with the outsole. In this regard, the stabilizing element may extend from the rear half of the shoe. Furthermore, the stabilizing element may extend from the heel region of the shoe and / or the sole region of the shoe. In accordance with the present invention, the heel region may be referred to as the region surrounding the wearer's heel and / or calcaneus. The entry opening may be referred to as the throat opening.
[0031] The use of at least two layers, i.e., an inner layer and an outer layer, can allow for stabilization gradation to be achieved. By way of example, areas of the shoe upper requiring less stabilization may be covered with only one layer, while areas requiring more stabilization may be covered with at least two layers. Furthermore, the use of at least two layers of stabilizing elements may provide a separation of functions. The inner layer may be stiffer than the outer layer and / or designed to provide a stable shape. The outer layer may be more elastic than the inner layer and / or designed to fasten the inner layer toward the interior of the shoe. Thus, using the separation of functions, the stabilizing element itself may be given a stable shape, and the stabilizing element may also provide sufficient pressure in the heel and / or ankle regions. Both aspects contribute to improved stabilization. Furthermore, in alternative embodiments, the outer layer may be stiffer than the inner layer and / or designed to provide a stable shape. The inner layer may be more elastic than the outer layer and / or designed to conform to the shape of the foot.
[0032] The stabilizing element may comprise additional layers in addition to the inner and outer layers. An adhesive layer may be applied between the inner layer and the outer layer of the shoe upper. Further illustratively, an adhesive layer may also be applied between the inner and outer layers.
[0033] The stabilizing element extending along the exterior of the shoe upper may be fixedly attached to the exterior of the shoe upper. Specifically, the inner layer and / or the outer layer may be sewn, glued, and / or heat welded to the exterior of the shoe upper. Thus, stabilization utilizing the stabilizing element may be further enhanced.
[0034] The area of the exterior of the shoe upper that is not covered by the stabilizing element and is located between the stabilizing element and the outsole may have a size of at least 100 mm, preferably at least 150 mm, more preferably at least 200 mm, even more preferably at least 250 mm, and most preferably at least 300 mm. These sizes ensure that pressure on the Achilles area is minimized. In particular, pressure on the Achilles tendon insertion can be at least partially avoided.
[0035] In a shoe according to a second alternative of the first embodiment, a portion of the exterior of the shoe upper that is not covered by the stabilizing element and is located between the stabilizing element and the outsole may transition continuously to a further portion of the exterior of the shoe upper that is not covered by the stabilizing element. In this regard, the further portion extends into a portion of the shoe upper that is configured to receive the Achilles region and / or the Achilles tendon insertion, and the further portion preferably extends from the lateral side of the shoe to the medial side of the shoe. The further portion may additionally prevent uncomfortable pressure on the Achilles region. In particular, the further portion may prevent the stabilizing element from exerting pressure on the Achilles tendon insertion. Furthermore, flexibility of the shoe upper may not be hindered by the stabilizing element in the Achilles region and / or at the Achilles tendon insertion. Therefore, shoe comfort may be improved and / or irritation of the Achilles tendon may be avoided.
[0036] The stabilizing element may have a wing-shaped, parallelogram-shaped, trapezoid-shaped, oval-shaped, and / or rectangular shape. In this regard, these shapes may include rounded edges. Furthermore, it will be understood that a clear geometric equivalent is not required. In particular, the inner layer and / or the outer layer may have a wing-shaped, parallelogram-shaped, trapezoid-shaped, oval-shaped, and / or rectangular shape. These shapes may serve to optimally cover the ankle area. In particular, a parallelogram shape may be advantageous because one side may be attached to or integrally molded with the outsole, in which case two parallel sides extend toward, and optionally into, the heel region and upward toward the foot opening. As noted above, a clear geometric equivalent of the parallelogram shape is not required. It will therefore be understood that with respect to the parallelogram shape, the two parallel sides extending towards, and optionally into, the heel region and extending upward towards the foot opening need not be exactly parallel.
[0037] The shape of the stabilizing element may be defined by at least two straight edges extending along the exterior of the shoe upper upward toward the foot opening and backward toward the heel region, the two edges preferably having a length of at least 10 mm, more preferably at least 15 mm, even more preferably at least 20 mm, and most preferably at least 25 mm. It will be understood that the straight edges do not necessarily have to be precisely straight in the geometric sense. The straight edges may be substantially straight in the geometric sense. This may include at least one of the straight edges being slightly curved, for example, with a decreasing or increasing slope as viewed from the surface defined by the outsole. The two straight edges may define the shape of the inner layer and / or the outer layer. In this regard, the angle between the outsole and at least one of the straight edges may be in the range of 5 to 70 degrees, preferably 10 to 60 degrees, more preferably 15 to 50 degrees, even more preferably 20 to 40 degrees, and most preferably 25 to 35 degrees. The two straight edges limit the shape of the stabilising element, thereby ensuring that no or reduced pressure is applied to the Achilles tendon insertion.
[0038] The inner and / or outer layer may each have a thickness of 0.01 mm to 3 mm, preferably 0.1 mm to 2 mm, more preferably 0.2 mm to 1 mm, even more preferably 0.25 mm to 0.5 mm, and most preferably 0.28 mm to 0.32 mm. This thickness range allows a good compromise between stiffness, i.e., foot stabilization, and comfort.
[0039] The stabilizing element may extend at least partially into the lateral ankle region or the medial ankle region. The term "ankle region" according to the present invention may generally refer to the region of the shoe upper that covers the region of the foot including the ankle, i.e., the ankle joint. The term "medial ankle region" according to the present invention may refer to the region of the shoe upper that covers the region of the foot including the ligaments between the tibia and the calcaneus. Furthermore, the term "lateral ankle region" according to the present invention may refer to the region of the shoe upper that covers the region of the foot including the ligaments between the fibula and the calcaneus.
[0040] The outer layer of the shoe stabilizing element according to the second alternative embodiment of the first aspect of the present invention may be integrally molded with the shoe outsole. In this context, "integrally molded" may refer to an embodiment in which no material boundary can be discerned between the outer layer and the outsole. Specifically, the outer layer and the outsole may be integrally formed by injection molding, direct casting, and / or foaming. Furthermore, the outer layer and the outsole may comprise a polymer material. Specifically, the outer layer and the outsole may comprise polyamide, polyurethane, and / or rubber. By integrally molding the outer layer with the outsole, the outer layer can be given a higher pre-tensioning force relative to the inner layer, thereby allowing for greater pressure to be applied to the wearer's heel area. Furthermore, the number of required work steps may be reduced.
[0041] The shape of the inner layer may correspond to the shape of the outer layer. The term "corresponding" may refer to an embodiment in which the shape of the outer layer is located within the inner layer and / or at least one edge of the inner layer and / or outer layer is substantially parallel. This allows load to be continuously transmitted between the inner layer and the outer layer. This can achieve uniform stress distribution. Therefore, damage to the material due to stress concentration can be avoided.
[0042] The medial layer may extend beyond the lateral layer. Preferably, the medial layer may extend beyond the lateral layer backward toward the Achilles region and / or upward toward the foot opening. Thus, the medial layer may improve support of the stabilizing element for the foot. Furthermore, the medial layer may extend beyond the lateral layer forward toward the toe region. The lateral layer may thereby serve to push the medial layer toward the interior of the shoe. Thus, the region of the shoe upper to be stabilized can be easily modified by adapting the medial layer, while the lateral layer can remain unchanged.
[0043] The inner layer may have a larger profile than the outer layer. In particular, the inner layer may serve to cover the area of the shoe upper that is to be stabilized, thereby pressing the inner layer toward the inside of the shoe. Thus, the area of the shoe upper that is to be stabilized can be easily modified by adapting the inner layer, while the outer layer can remain unchanged.
[0044] The inner layer may consist of a composite layer, which is preferably a fiber-reinforced layer. The term "composite" may refer to an embodiment in which the layer is made of at least two materials with different material properties. In this regard, the composite layer may comprise a fiber-reinforced polymer. In particular, the composite layer may comprise a carbon fiber-reinforced polymer, a glass fiber-reinforced polymer, a natural fiber-reinforced polymer, a ceramic fiber-reinforced polymer, and / or an aramid fiber-reinforced polymer. Thus, the inner layer may provide higher strength and / or stiffness. Furthermore, the weight of the inner layer may be reduced.
[0045] Additionally, the inner layer may have anisotropic material properties, which can be used to tailor the inner layer to specific load cases. By way of example, fibers within the inner layer may be oriented to provide high bending stiffness and low torsional stiffness. Thus, the shoe may provide flexibility while simultaneously providing stability to prevent ankle sprains.
[0046] The outer layer may include at least one of the following materials: ethylene vinyl acetate (EVA), polyamide 11 (PA11), polyamide 12 (PA12), polyether block amide (PEBA), and / or thermoplastic elastomer (TPE), such as thermoplastic polyurethane (TPU). Therefore, the outer layer may provide high rigidity for fastening the inner layer to the shoe upper. Furthermore, the outer layer may be integrally molded with the outsole.
[0047] The outer layer may have a triangular cross section. In this regard, the cross section of the outer layer may have three corners. The corners may be at least partially rounded. Furthermore, the cross section of the outer layer may have three edges. In this regard, the three edges may be straight or partially curved. In particular, one edge and / or two of the corners may be in contact with the inner layer. The triangular cross section increases the area moment of inertia of the outer layer, particularly compared to a substantially rectangular cross section having the same area. Therefore, the rigidity of the outer layer may be improved.
[0048] The outer layer may have a varying thickness. Illustratively, a first portion of the outer layer may have a greater thickness than a second portion of the outer layer. Illustratively, the first and second portions may be separated by a step in the surface of the outer layer. The step may be a discontinuous change in the surface of the outer layer.
[0049] The outer layer may comprise a reinforcing rib. The reinforcing rib may comprise a step, as defined above, dividing the first and second portions of the outer layer. The reinforcing rib may extend from the outsole along the outer layer of the stabilizing element. Preferably, the outer layer of the stabilizing element is integrally formed with the outsole or an outsole component. The reinforcing rib may extend essentially along the entire length of the stabilizing element. The reinforcing rib may extend at least partially along the outsole. The reinforcing rib increases the area moment of inertia of the outer layer. This may therefore improve the stiffness of the outer layer.
[0050] The outer layer may be a composite layer, which can further increase the rigidity of the stabilizing element, thereby providing the stabilizing element with even greater stability.
[0051] The outsole may comprise multiple parts. By way of example, the outsole may be formed as a modular assembly. In this regard, at least one module of the modular assembly of the outsole may be a composite module. The composite module is preferably a fiber-reinforced module. The term "composite" may refer to an embodiment in which a part is made of at least two materials with different material properties. In this regard, the composite module may comprise a fiber-reinforced polymer. In particular, the composite module may comprise a carbon fiber-reinforced polymer, a glass fiber-reinforced polymer, a natural fiber-reinforced polymer, a ceramic fiber-reinforced polymer, and / or an aramid fiber-reinforced polymer. By way of example, but not limitation, the composite module may be a plate or a rod. The outsole may comprise multiple composite modules.
[0052] Furthermore, at least one module may be connected to the inner and / or outer layer of the stabilizing element. In particular, the module may be integrally molded with the inner and / or outer layer. In this regard, "integrally molded" may refer to an embodiment in which no material boundary can be discerned between the outer layer and the module.
[0053] Furthermore, a line on the exterior of the shoe upper, extending substantially straight along the Achilles region from the outsole to the opening, may not be covered by the medial and / or lateral layers. In this regard, the line is preferably not covered by a stabilizing element. A line on the exterior of the shoe upper, extending substantially straight along the Achilles region from the outsole to the opening, and not covered by the medial and / or lateral layers, may increase the mobility of the Achilles tendon, improving comfort and / or functionality. This is because the influence of the medial and / or lateral layers on the stretch and / or relaxation of the Achilles tendon is at least reduced. In particular, this is because the stretch and / or relaxation of the Achilles tendon may then be limited primarily by the material of the shoe upper. These advantages are particularly relevant when the shoe includes two stabilizing elements, as described below.
[0054] The shoe may include two stabilizing elements as defined above, with a first stabilizing element located on the lateral side of the shoe and, more preferably, a second stabilizing element located on the medial side of the shoe. This may provide a shoe with improved lateral and medial stability, thereby reducing the risk of sprains in the lateral and medial directions. Furthermore, the stabilizing elements, as described above, may avoid applying pressure to the Achilles region, particularly the Achilles tendon insertion.
[0055] The inner layer of the first stabilizing element and the inner layer of the second stabilizing element may be connected to each other by a first connecting element. The first connecting element may extend at least partially along the sole region of the shoe. The first connecting element may be integrally molded with the inner layer of the first stabilizing element and the inner layer of the second stabilizing element.
[0056] The medial layer of the first stabilizing element and the medial layer of the second stabilizing element may be connected to a module of the modular outsole assembly. Specifically, the medial layers may be integrally molded with the module as described above. Furthermore, the medial layer of the first stabilizing element and the medial layer of the second stabilizing element may be connected to the same module of the modular outsole assembly. Thus, the medial layers may be connected to each other via the module. This may further improve stabilization without applying pressure to the Achilles region, particularly the Achilles tendon insertion.
[0057] The outer layer of the first stabilizing element and the outer layer of the second stabilizing element may be connected to each other by a second connecting element. The second connecting element may extend at least partially along the sole region of the shoe. The second connecting element may be integrally molded with the outer layer of the first stabilizing element and the outer layer of the second stabilizing element.
[0058] The outer layer of the first stabilizing element and the outer layer of the second stabilizing element may be connected to a module of the modular outsole assembly. Specifically, the outer layer may be integrally molded with the module as described above. Furthermore, the outer layer of the first stabilizing element and the outer layer of the second stabilizing element may be connected to the same module of the modular outsole assembly. Thus, the outer layers may be connected to each other via the module. This may further improve stabilization without applying pressure to the Achilles region, particularly the Achilles tendon insertion.
[0059] The first stabilizing element may extend at least partially into the lateral ankle region and the second stabilizing element may extend at least partially into the medial ankle region, thereby further protecting the ankle, i.e., the ankle joint, from sprains and / or injuries.
[0060] The first stabilizing element and the second stabilizing element may be configured to help anchor the calcaneus, thereby preferably avoiding pressure on the Achilles region and / or Achilles tendon insertion. Anchoring the calcaneus may secure the wearer's heel within the shoe. Securing the wearer's heel within the shoe may prevent instability due to heel slippage within the shoe. Avoiding pressure on the Achilles region and / or Achilles tendon insertion may improve comfort and reduce the risk of irritation and even inflammation.
[0061] Additionally, the first stabilizing element and the second stabilizing element may not cover portions of the shoe upper configured to receive the Achilles region and / or Achilles tendon insertion. Thus, portions of the shoe upper configured to receive the Achilles region and / or Achilles tendon insertion may remain uncovered by the stabilizing elements. Avoiding coverage of such portions may avoid applying pressure to the Achilles region and / or Achilles tendon insertion, thereby improving comfort and reducing the risk of irritation and even inflammation.
[0062] The first stabilizing element and the second stabilizing element may be spaced apart by a distance that extends along the exterior of the shoe upper and at least partially along the Achilles region. This may avoid uncomfortable pressure on the Achilles region. Specifically, the stabilizing elements may be prevented from exerting pressure on the Achilles tendon insertion. This may improve shoe comfort and / or avoid irritation of the Achilles tendon. It will be appreciated that because the distance extends at least partially along the Achilles region and along the exterior of the shoe upper, the distance may be represented by a curve. Furthermore, the distance may be measured from the most posterior point of the first stabilizing element to the most posterior point of the second stabilizing element. The distance may be in the range of 10 mm to 50 mm, preferably in the range of 20 mm to 35 mm, and more preferably in the range of 25 mm to 30 mm. This distance has been found to provide sufficient stabilization while simultaneously avoiding pressure on the Achilles region. The distance may be measured in a plane perpendicular to the plane of the flared outsole of the shoe.
[0063] Additionally, at least one of the inner and outer layers of the stabilizing element may be located between the innermost and outermost layers of the shoe upper, and thus may extend along the exterior of the inner or intermediate layer of the shoe upper.
[0064] As stated above, the first object underlying the present invention is at least partly achieved by the second aspect of the present invention.
[0065] A second aspect of the present invention is a shoe, comprising: Shoe upper and The outsole and a first stabilizing element, a first stabilizing element extending from a lateral side of the outsole upward toward an entry opening in the shoe upper and rearward toward (e.g., into) a heel region of the shoe; a first stabilizing element comprising an inner layer and an outer layer; a first stabilizing element, the first stabilizing element extending along an exterior of the shoe upper; a second stabilizing element, a second stabilizing element extending from a medial side of the outsole upward toward an entry opening in the shoe upper and rearward toward (e.g., into) a heel region of the shoe; a second stabilizing element comprising an inner layer and an outer layer; a second stabilizing element, the second stabilizing element extending along an exterior of the shoe upper; The shoe includes a first stabilizing element and a second stabilizing element spaced apart by a distance that extends along an exterior of the shoe upper and at least partially along the Achilles region.
[0066] The shoe according to the second aspect of the present invention may avoid uncomfortable pressure on the Achilles region. Specifically, pressure from the stabilizing element on the insertion of the Achilles tendon may be avoided. Therefore, shoe comfort may be improved and / or irritation of the Achilles tendon may be avoided. It will be appreciated that the distance may be represented by a curve, since it extends at least partially along the Achilles region and along the exterior of the shoe upper. Furthermore, the distance may be measured from the most posterior point of the first stabilizing element to the most posterior point of the second stabilizing element. The distance may be in the range of 10 mm to 50 mm, preferably in the range of 20 mm to 35 mm, and more preferably in the range of 25 mm to 30 mm. It has been found that this distance provides sufficient stabilization while simultaneously avoiding pressure on the Achilles region. The distance may be measured in a plane perpendicular to the plane of the shoe outsole's extension. The top most posterior edge of a first stabilizing element according to the first aspect of the invention may comprise said top most posterior point of the first stabilizing element. The top most posterior edge of a second stabilizing element according to the first aspect of the invention may comprise said top most posterior point of the second stabilizing element. Furthermore, in alternative embodiments, the distance may be measured from the top most posterior edge of the first stabilizing element to the top most posterior edge of the second stabilizing element.
[0067] In the shoe according to the second aspect of the present invention, a line on the exterior of the shoe upper that extends substantially straight along the Achilles region from the outsole to the foot opening may not be covered by the medial and / or lateral layers of the first and / or second stabilizing elements. In this regard, the line is preferably not covered by either the first or second stabilizing element. The line on the exterior of the shoe upper that extends substantially straight along the Achilles region from the outsole to the foot opening and that is not covered by the medial and / or lateral layers of the first and / or second stabilizing elements may increase the mobility of the Achilles tendon, improving comfort and / or functionality. This is because the influence of the medial and / or lateral layers on the stretch and / or relaxation of the Achilles tendon is at least reduced. In particular, this is because the stretch and / or relaxation of the Achilles tendon may then be limited primarily by the material of the shoe upper.
[0068] It is understood that features of the first aspect of the invention may be combined with the second aspect of the invention. In particular, the first stabilizing element and / or the second stabilizing element of the second aspect of the invention may comprise the features of the stabilizing element of the first aspect of the invention described herein. Thus, advantages of the first aspect of the invention may also apply to the second aspect of the invention, and vice versa.
[0069] As stated above, the first object underlying the present invention is at least partly achieved by the third aspect of the present invention.
[0070] A third aspect of the present invention relates to a shoe comprising a shoe upper, an outsole, and a stabilizing element. The stabilizing element extends from the outsole upward toward the shoe upper's entry opening and rearward toward the shoe's heel region. The stabilizing element further comprises an inner layer and an outer layer. The stabilizing element further extends along the exterior of the shoe upper. The stabilizing element further extends at least partially along the midfoot region of the upper. The midfoot region may include a region of the upper corresponding to the metatarsals. It is understood that features of the first aspect of the present invention may be applied to the third aspect of the present invention. In particular, the first stabilizing element of the third aspect of the present invention may comprise the features of the stabilizing element of the first aspect of the present invention described herein. Accordingly, advantages of the first aspect of the present invention may also apply to the third aspect of the present invention, and vice versa.
[0071] Furthermore, when the shoe is worn, the rearmost edge of the stabilizing element may be positioned forward from the ankle on one side of the foot on which the stabilizing element is positioned. Furthermore, the stabilizing element may substantially anchor the midfoot portion of the wearer's foot. Furthermore, the stabilizing element may extend from the front half of the shoe. In this regard, the proposed shape of the stabilizing element of the first aspect of the present invention may enable the stabilizing element to adapt to the shape of the wearer's foot and provide improved stabilization in the midfoot portion.
[0072] As stated above, the second object underlying the present invention is at least partly achieved by the fourth aspect of the present invention.
[0073] A fourth aspect of the present invention relates to a method for manufacturing at least one containment element in a shoe upper, the method comprising the steps of providing a shoe upper, embossing at least one recess in the shoe upper, and at least partially filling the recess with foam.
[0074] The containment element according to the present invention may be referred to as an embossed depression that is at least partially filled with foam. The containment element is positioned to keep the wearer's foot secured within the shoe. In particular, the containment element may serve to contain the wearer's foot within the shoe. Furthermore, the containment element may prevent the foot from slipping off in the midfoot area of the shoe.
[0075] The shoe upper may comprise a polymeric material and / or a natural material, such as leather and / or natural fibers. Furthermore, the shoe upper may comprise a woven material, a knitted material, a material with unidirectional fibers, and / or a material without fibers. The shoe upper may be for a sports shoe, a day shoe, a casual shoe, and / or a work shoe. Furthermore, the shoe upper may be for a soccer shoe, a running shoe, a hiking boot, a climbing boot, a ski boot, a cross-country ski boot, and / or a basketball shoe. The above examples are not intended to be exhaustive.
[0076] The embossing step creates the necessary space for the foam. Furthermore, the embossing step reduces the relaxation and / or stretching of the formed depressions, which are at least partially filled with foam. This allows for greater rigidity and therefore stability of the containment element, which is particularly required for shoes without laces, such as laceless soccer shoes.
[0077] The embossing step may be performed using an embossing machine. The embossing machine may include a positive die and / or a negative die. Furthermore, the embossing step may include heating the shoe upper and / or at least one die, so that the material of the shoe upper may at least partially exceed its glass transition temperature during embossing. Furthermore, the shoe upper may be at least partially melted during embossing, so that the shape of the depression may be permanently formed.
[0078] During embossing, the surface adjacent to the indentation may be at least partially melted and / or compressed, thus increasing the hardness of the adjacent surface, which may further improve the stability of the containment element.
[0079] The foam in the recess may be compressed when the foot is inserted into the shoe upper. Due to this compression, the foam may exert pressure against the foot. The pressure may prevent the foot from slipping out of the shoe upper. The foam may be a polymer foam. Specifically, the foam may be ethylene vinyl acetate foam, neoprene foam, polyurethane foam, polyethylene foam, polystyrene foam, or polyethylene terephthalate foam. Ethylene vinyl acetate foam and neoprene foam, in particular, provide high durability against environmental conditions.
[0080] The method may further include providing a layer over the indentation, thereby at least partially closing the indentation. Furthermore, the indentation may be completely closed by the layer. The layer may be a fabric layer, such as a mesh fabric layer. Furthermore, the layer may serve to secure and / or protect the foam inside the indentation. This layer prevents irritation to the foot in contact with the shoe upper from the edges of the embossed indentation.
[0081] The indentations may be embossed on the inner surface of the shoe upper such that the shape of the indentations preferably protrudes on the exterior of the shoe upper, and the foam may therefore protrude into the interior of the shoe upper, so that the foam may exert pressure on the foot in contact with the inner surface of the shoe upper.
[0082] The foam may protrude medially and / or laterally from the shoe upper relative to a surface of the shoe upper adjacent the indentation that is not embossed, so that the foam has sufficient volume to be compressed and thereby exert sufficient force on a foot in contact with the shoe upper.
[0083] The recesses may be embossed on the lateral and / or medial sides of the shoe upper, so that the lateral and / or medial sides of the foot can be secured inside the shoe upper.
[0084] The recesses may have cross sections that are at least partially circular, oval, elliptical, triangular, and / or rectangular. The cross sections may allow for tailoring of the spring and / or damping characteristics of the containment element. By way of example, a triangular cross section may provide a more gradual spring characteristic than a rectangular cross section. The gradual spring characteristic may provide comfort while at the same time providing sufficient protection against slipping off the shoe upper.
[0085] The recess may be elongated along the shoe upper, so that when the foot contacts the shoe upper, the foam inside the recess can apply force along the shoe upper. Thus, multiple parts of the foot can be fixed and / or damped. Furthermore, the force applied to the foot can be dispersed. Therefore, the shoe upper can be more comfortable.
[0086] The recess may extend from the ankle region of the shoe upper into the midfoot region of the shoe upper. Specifically, the recess may extend from the ankle region of the shoe upper into the midfoot region at the top of the shoe upper. This can prevent the foot from slipping off at the midfoot region. Furthermore, at the same time, the foot can be prevented from slipping off at the ankle region.
[0087] The term "ankle" in the present invention may also be referred to as the ankle joint. Furthermore, the term "ankle region" in the present invention generally refers to the region of the shoe upper that covers the region of the foot including the ankle, i.e., the ankle joint. The term "medial ankle region" in the present invention may refer to the region of the shoe upper that covers the region of the foot including the ligament between the tibia and the calcaneus. Furthermore, the term "lateral ankle region" in the present invention may refer to the region of the shoe upper that covers the region of the foot including the ligament between the fibula and the calcaneus.
[0088] The recess may have a length and a width, with the length to width ratio being preferably 5 to 18, more preferably 7 to 16, even more preferably 9 to 14, and most preferably 10 to 12. In this regard, the ratio may be determined by the maximum width and / or the maximum length. These ratios provide improved stabilization while at the same time being comfortable for the wearer's foot. In a particularly preferred embodiment, the length to width ratio is 5 to 8.
[0089] The recess may extend along 20% to 80% of the length of the shoe upper, preferably 25% to 75%, more preferably 30% to 65%, even more preferably 40% to 60%, and most preferably 45% to 55%. These ranges have been found to provide sufficient pressure on the wearer's foot while avoiding excessive recess space.
[0090] The cross-sectional area and / or width of the recess may reach a maximum value at the middle of the recess, preferably spaced from one end by a distance equal to the length of the recess multiplied by a factor of 0.3 to 0.7, preferably 0.35 to 0.65, more preferably 0.4 to 0.6, even more preferably 0.45 to 0.55, and most preferably 0.48 to 0.52. This allows the foam of the containment element to apply the greatest pressure to the part of the foot located centrally between the top midfoot area and the ankle area. This part of the foot, which is most susceptible to slipping off, therefore experiences the greatest pressure. Furthermore, the foot may be pushed backward within the shoe upper into the heel area, which may provide additional protection against slipping off.
[0091] The cross-sectional area of the recess and / or the width of the recess may reach a minimum in the midfoot and / or ankle regions. This allows the pressure of the containment element to decay towards the ends. This may therefore improve comfort for the wearer. Furthermore, pressure may be reduced in areas where less pressure is needed and / or where pressure is uncomfortable, i.e., the ankle and / or midfoot regions.
[0092] The first recess may be embossed on the lateral side of the shoe upper, and the second recess may be embossed on the medial side of the shoe upper. Thus, the lateral and medial sides of the foot may be equally secured against slip-off. The second recess may be located higher than the first recess, i.e., closer to the foot opening. Thus, the positioning of the containment element is adapted to the anatomy of the wearer's foot. It will be understood that the first recess and the second recess may be at least partially filled with foam.
[0093] Furthermore, the second object of the present invention is at least partially achieved by a shoe upper comprising at least one containment element, the containment element being manufactured by the method as described above.
[0094] Furthermore, the second object of the present invention is at least partially achieved by a shoe comprising the shoe upper described in the preceding paragraph. In this regard, the shoe may be a sports shoe, a day shoe, a casual shoe, and / or a work shoe. Furthermore, the shoe may be a soccer shoe, a running shoe, a mountaineering boot, a climbing boot, a ski boot, a cross-country ski boot, and / or a basketball shoe. The above examples are not intended to be exhaustive.

[Figure 12] 1 is a detailed view of a second exemplary shoe according to the first, second and fourth embodiments of the present invention. DETAILED DESCRIPTION OF THE INVENTION
[0097] FIG. 1 shows an exemplary shoe 1 according to a first embodiment of the present invention in a side view. The shoe 1 is a soccer shoe. However, it is understood that the shoe may also be a running shoe, a mountaineering boot, a climbing boot, a ski boot, a cross-country ski boot, and / or a basketball shoe. Furthermore, the shoe may be any other sports shoe, a day shoe, a casual shoe, and / or a work shoe. The above examples are not intended to be exhaustive.
[0098] FIG. 1 according to a first embodiment of the invention shows a shoe 1 comprising a shoe upper 2 , an outsole 3 and a stabilizing element 10 .
[0099] The stabilizing element 10 serves to secure the wearer's heel within the shoe 1 and to stabilize the wearer's ankle. By securing the wearer's heel within the shoe 1, instability due to heel slippage within the shoe can be avoided. Furthermore, by stabilizing the wearer's ankle, ankle sprains can be avoided.
[0100] The stabilizing element 10 extends from the outsole 3 upward toward the entry opening 4 of the shoe upper 2 and rearward toward the heel region 5 of the shoe 1. In particular, the stabilizing element 10 extends rearward into the heel region 5 of the shoe 1. The stabilizing element 10 comprises an outer layer 12. Furthermore, the stabilizing element 10 extends along the exterior 6 of the shoe upper 2. The outer layer 12 is thereby in contact with the exterior 6 of the shoe upper 2. It will be understood that the outer layer 12 may be attached to the exterior 6 of the shoe upper 2 by, for example, heat welding, gluing, and / or sewing. Furthermore, a portion 13 of the exterior 6 of the shoe upper 2 located between the stabilizing element 10 and the outsole 3 is not covered by the stabilizing element 10.
[0101] The area 13 not covered by the stabilizing element 10 avoids or at least reduces pressure on the Achilles area. In particular, the area may prevent the stabilizing element 10 from exerting pressure on the insertion of the Achilles tendon. Thus, the comfort of the shoe 1 may be improved and / or irritation of the Achilles tendon may be avoided.
[0102] As further shown in FIG. 1 and in accordance with a first aspect of the present invention, the outer layer 12 of the stabilizing element 10 is integrally molded with the outsole 3 of the shoe 1. By integrally molding the outer layer with the outsole, a higher pre-tensioning of the outer layer can be achieved, thereby allowing for greater pressure to be applied to the heel area of the wearer. Furthermore, fewer manufacturing steps are required. It will be appreciated that in FIG. 1, the stabilizing element comprises only one layer, and therefore the "outer layer" may be more generally referred to as a "layer."
[0103] 2 shows an exemplary shoe 1 in side view according to the first and fourth embodiments of the present invention. The shoe 1 is a laceless soccer shoe. However, it is understood that the shoe may also be a running shoe, a mountaineering boot, a climbing boot, a ski boot, a cross-country ski boot, and / or a basketball shoe. Furthermore, the shoe may be any other sports shoe, a day shoe, a casual shoe, and / or a work shoe. The above examples are not intended to be exhaustive.
[0104] FIG. 2 according to a first embodiment of the invention shows a shoe 1 comprising a shoe upper 2 , an outsole 3 and a stabilizing element 10 .
[0105] The stabilizing element 10 serves to secure the wearer's heel within the shoe 1 and to stabilize the wearer's ankle. By securing the wearer's heel within the shoe 1, instability due to heel slippage within the shoe can be avoided. Furthermore, by stabilizing the wearer's ankle, ankle sprains can be avoided.
[0106] The stabilizing element 10 extends from the outsole 3 upward toward the entry opening 4 of the shoe upper 2 and backward toward or into the heel region 5 of the shoe 1. The stabilizing element 10 comprises an inner layer 11 and an outer layer 12. Furthermore, the stabilizing element 10 extends along the exterior 6 of the shoe upper 2. Furthermore, a region 13 of the exterior 6 of the shoe upper 2, which is located between the stabilizing element 10 and the outsole 3, is not covered by the stabilizing element 10. The inner layer 11 and the outer layer 12 are made of different materials.
[0107] The area 13 not covered by the stabilizing element 10 avoids or at least reduces pressure on the Achilles area. In particular, the area (13) may prevent the stabilizing element 10 from exerting pressure on the insertion of the Achilles tendon. Thus, the comfort of the shoe 1 may be improved and / or irritation of the Achilles tendon may be avoided.
[0108] The region 13 of the exterior 6 of the shoe upper 2 that is not covered by the stabilizing element 10 and is located between the stabilizing element 10 and the outsole 3 transitions continuously into a further region 18 of the exterior 6 of the shoe upper 2 that is not covered by the stabilizing element 10. In this regard, as shown in more detail in FIGS. 7 and 11 , for example, the further region 18 extends into a portion of the shoe upper 2 that is configured to receive the Achilles region and / or the Achilles tendon insertion, such that the further region 18 extends from the lateral side of the shoe 1 to the medial side of the shoe 1. The further region 18 may prevent uncomfortable pressure on the Achilles region. In particular, the further region 18 may prevent the stabilizing element 10 from exerting pressure on the Achilles tendon insertion. Furthermore, the flexibility of the shoe upper 2 may not be hindered by the stabilizing element 10 in the Achilles region and / or at the Achilles tendon insertion. Therefore, the comfort of the shoe 1 may be improved and / or irritation of the Achilles tendon may be avoided.
[0109] The use of different materials allows for the separation of functions. The inner layer is preferably made of a material with higher rigidity and / or strength than the outer layer. Furthermore, the outer layer may be made of a material with higher elasticity than the inner layer. Thus, the inner layer can provide rigidity and / or strength, while the outer layer can fasten the inner layer to the shoe upper. As such, the stabilizing element can be firmly fastened to the wearer's heel and / or ankle, thereby improving stability. Furthermore, the distinct use of materials can reduce the weight of the stabilizing element. Furthermore, the inner layer can be adapted to the characteristics of the wearer's foot, while the outer layer can remain unchanged. Therefore, the use of different materials and the separation of functions within the stabilizing element can reduce the effort required for modification.
[0110] Further according to the first aspect of the present invention, the shoe 1 of FIG. 2 comprises two stabilizing elements 10, 15, with the first stabilizing element 10 being arranged on the lateral side of the shoe 1 and the second stabilizing element 15 being arranged on the medial side of the shoe 1. The second stabilizing element 15 is hidden in FIG. 2 but is shown in FIG. 4. The first stabilizing element 10 extends at least partially into the lateral ankle region 7a. The first stabilizing element 10 and the second stabilizing element 15 are configured to anchor the calcaneus, thereby removing pressure from the Achilles tendon insertion.
[0111] 2 according to a fourth embodiment of the present invention shows a shoe 1 with a shoe upper 2, the shoe upper 2 being provided with a containment element 20. The containment element 20 was manufactured according to the method 100 shown in FIG.
[0112] FIG. 3 shows a detailed view of the rear portion of an exemplary shoe in side view according to the first and fourth embodiments of the present invention.
[0113] 3 according to the first embodiment of the invention shows that the shape of the stabilizing element 10 is limited by at least two straight edges 14a, 14b that extend along the exterior 6 of the shoe upper 2 upwards towards the entry opening and backwards towards the heel area 5. In this regard, the two edges 14a, 14b have a length of at least 15 mm. As said two straight edges 14a, 14b limit the shape of the stabilizing element 10, it can be ensured that no or only reduced pressure is applied to the Achilles tendon insertion.
[0114] 3, and in accordance with a first embodiment of the present invention, the outer layer 12 of the stabilizing element 10 is integrally molded with the outsole 3 of the shoe 1. By integrally molding the outer layer with the outsole, the outer layer can be given a higher pre-tensioning force relative to the inner layer, thereby applying more pressure to the heel area of the wearer. Additionally, fewer manufacturing steps are required.
[0115] The shape of the inner layer 11 corresponds to the shape of the outer layer 12. This allows loads to be continuously transferred between the inner and outer layers. This allows uniform stress distribution to be achieved. Therefore, material damage due to stress concentration can be avoided. Furthermore, the inner layer 11 has a larger outer profile than the outer layer 12. This allows the inner layer to cover the area of the shoe upper that needs to be stabilized, and the outer layer to press the inner layer toward the inside of the shoe.
[0116] The inner layer 11 preferably consists of a composite layer, which is preferably a fiber reinforced layer.
[0117] FIG. 4 shows a detailed view of the rear portion of an exemplary shoe according to the first and fourth embodiments of the present invention, viewed from the inside.
[0118] 4, in accordance with a first aspect of the present invention, shows a stabilizing element 15 extending at least partially into the medial ankle region 7b. What has been described above with respect to the stabilizing element 10 located on the lateral side of the shoe upper applies equally to the stabilizing element 15 located on the medial side of the shoe upper. However, in other embodiments, the lateral and medial stabilizing elements may differ, for example, with respect to their size, shape, material, etc.
[0119] FIG. 5 shows a detailed side view of an exemplary shoe according to the first and fourth embodiments of the present invention.
[0120] 5 according to a fourth embodiment of the present invention shows a detail of the shoe 1 shown in FIG. 2, the shoe 1 comprising a shoe upper 2, the shoe upper 2 comprising a containment element 20. The containment element 20 has been manufactured according to a method 100 shown in FIG. 6. The method 100 includes a step 110 of providing a shoe upper 2, a step 120 of embossing at least one recess 21 in the shoe upper 2, and a step 130 of at least partially filling the recess 21 with foam. Furthermore, the method 100 may further include a step 140 of providing a layer over the recess 21, thereby at least partially closing the recess 21.
[0121] As shown, the indentation 21 is embossed 120 into the inner surface 30 of the shoe upper 2 such that the shape of the indentation 21 protrudes onto the exterior 6 of the shoe upper 2. In this regard, the hidden foam may protrude medially and / or laterally from the shoe upper 2 compared to the surface 23 of the shoe upper 2 adjacent the indentation 21 that was not embossed.
[0122] The recess 21 is embossed on the lateral side of the shoe upper 2 and has a cross-section that is at least partially triangular. Furthermore, the recess 21 is elongated along the shoe upper 2. In this regard, the recess 21 extends from the ankle region 7a of the shoe upper 2 into the midfoot region 8 of the shoe upper 2. Specifically, in FIG. 5, the recess 21 extends from the lateral ankle region 7a, whereas in FIG. 4, the recess 21 extends from the medial ankle region 7b. In this regard, the recess 21 extends along 30% to 65% of the length of the shoe upper 2. This range provides sufficient pressure on the wearer's foot while avoiding excessive recess space.
[0123] Furthermore, the cross-sectional area and width of recess 21 reach a maximum value at the middle of recess 21, which is spaced from one end of recess 21 by a distance equal to the length of recess 21 multiplied by a factor of 0.45 to 0.55. This causes the foam of the containment element to exert the greatest pressure on the part of the foot located midway between the top midfoot and ankle areas. This part of the foot, which is most susceptible to slipping off, therefore receives the greatest pressure. Furthermore, the foot may be pushed backward within the shoe upper and into the heel area, which may provide additional protection against slipping off.
[0124] Furthermore, the cross-sectional area of the recess 21 and the width of the recess 21 reach a minimum at the midfoot region 8 and the ankle regions 7a, 7b, which allows the pressure of the containment element to decay towards the ends, thus improving comfort for the wearer.
[0125] 4 and 5, the first recess 21 is embossed on the lateral side of the shoe upper 2, and the second recess 26 is embossed on the medial side of the shoe upper 2. Thus, the lateral and medial sides of the foot are equally secured against slipping off.
[0126] 6 shows an exemplary method 100 for manufacturing at least one containment element 20 in a shoe upper 2 according to a fourth aspect of the present invention. Method 100 includes step 110 of providing a shoe upper 2, step 120 of embossing at least one recess 21 in the shoe upper 2, and step 130 of at least partially filling recess 21 with foam. Additionally, method 100 may further include step 140 of providing a layer over recess 21, thereby at least partially closing recess 21.
[0127] FIG. 7 illustrates a rear view of a second exemplary shoe 1 according to the first, second, and fourth embodiments of the present invention. In this regard, the first stabilizing element 10 and the second stabilizing element 15 are spaced apart by a distance 30 that extends at least partially along the Achilles region and along the exterior of the shoe upper 2. This avoids uncomfortable pressure on the Achilles region. In particular, the stabilizing elements 10 and 15 are prevented from exerting pressure on the insertion of the Achilles tendon. This can improve the comfort of the shoe 1 and / or avoid irritation of the Achilles tendon. As shown in FIG. 7, the distance 30 is measured from the most posterior point of the first stabilizing element 10 to the most posterior point of the second stabilizing element 15.
[0128] Further in accordance with a second aspect of the present invention, FIG. 7 illustrates a second exemplary shoe 1 including a shoe upper 2, an outsole 3, a first stabilizing element 10, and a second stabilizing element 15. The first stabilizing element 10 extends from a lateral side of the outsole 3 upward toward the entry opening 4 of the shoe upper 2 and rearward into the heel region 5 of the shoe 1. The first stabilizing element 10 further includes an inner layer 11 and an outer layer 12. The first stabilizing element 10 further extends along the exterior 6 of the shoe upper 2. The second stabilizing element 15 extends from a medial side of the outsole 3 upward toward the entry opening 4 of the shoe upper 2 and rearward into the heel region 5 of the shoe 1. The second stabilizing element 15 further includes an inner layer 16 and an outer layer 17. The second stabilizing element 15 further extends along the exterior 6 of the shoe upper 2. The first stabilizing element 10 and the second stabilizing element 15 are spaced apart by a distance 30 that extends along the exterior 6 of the shoe upper 2 and at least partially along the Achilles region.
[0129] While only Figures 7 and 12 illustrate the first and second stabilizing elements proposed by the second aspect of the present invention, it will be understood that features shown in Figures 8, 10, and 11 may also form part of the second aspect of the present invention, since Figures 7, 8, and 10-12 all illustrate a second exemplary shoe. It will also be understood that features of the first exemplary shoe may form part of the second aspect of the present invention, since, as shown in Figures 2 and 4, the first exemplary shoe also includes first and second stabilizing elements as proposed by the second aspect of the present invention.
[0130] FIG. 8 shows a bottom view of a second exemplary shoe 1 according to the first and fourth embodiments of the present invention. As shown, the outsole 3 includes an embedded carbon sole insert 40, which may be referred to as a composite module as described above. Thus, the inner layers of the stabilizing elements 10, 15 can be connected to each other via the carbon sole insert 40, i.e., the composite module. The same applies to the outer layers. This can further improve stabilization without adding pressure to the Achilles region, particularly the Achilles tendon insertion.
[0131] 9 shows a front view of a third exemplary shoe 1 according to a fourth embodiment of the present invention. As shown, a first recess 21 is embossed on the lateral side of the shoe upper 2, and a second recess 26 is embossed on the medial side of the shoe upper 2. This allows the lateral and medial sides of the foot to be equally secured against slip-off. As further shown, the second recess 26 is located higher than the first recess 21, i.e., closer to the foot opening 4. Thus, the positioning of the containment elements 20, 25 is adapted to the anatomy of the wearer's foot.
[0132] FIG. 10 shows a second exemplary shoe according to the first and fourth embodiments of the present invention from an inside view.
[0133] According to the first embodiment of the present invention, the medial layer 16 of the second stabilizing element 15 extends beyond the lateral layer 17 of the second stabilizing element 15. In particular, the medial layer 16 extends backward toward the Achilles region and upward toward the foot opening beyond the lateral layer 17. Thus, the medial layer can improve the support of the stabilizing element relative to the foot. Furthermore, the medial layer 16 extends forward beyond the lateral layer 17 toward the toe region. This allows the lateral layer 17 to serve to push the medial layer 16 toward the interior of the shoe 1. Thus, the region of the shoe upper 2 to be stabilized can be easily modified by adapting the medial layer 16, while the lateral layer 17 can remain unchanged.
[0134] In further accordance with the first aspect of the present invention, the shape of the inner layer 16 of the second stabilizing element 15 corresponds to the shape of the outer layer 17 of the second stabilizing element 15. Specifically, the shape of the outer layer 17 is located within the inner layer, and the three edges of the inner and outer layers are substantially parallel. This allows loads to be continuously transferred between the inner and outer layers, thereby achieving uniform stress distribution.
[0135] According to a fourth aspect of the present invention, the embossed second recess 26 of the second confinement element 25 has a cross section that is at least partially circular. Compared to the substantially triangular cross section exemplarily shown in Figures 2 to 5, a less progressive spring characteristic may be obtained. The less progressive spring characteristic may provide improved comfort.
[0136] FIG. 11 shows a detailed view of a second exemplary shoe 1 according to the first and fourth embodiments of the present invention. As shown, the outer layer 17 of the second stabilizing element 15 has a varying thickness. Specifically, steps 51 on the surface of the outer layer 17 separate portions of the outer layer 17 having different thicknesses. The steps 51 are discontinuous changes on the surface of the outer layer 17. As further shown, the outer layer 17 includes a reinforcing rib 50 that includes the steps 51. As shown in FIG. 12, the first stabilizing element 10 also includes a reinforcing rib 50, similar to the second stabilizing element 15.
[0137] 12 shows a detailed view of a second exemplary shoe according to the first, second, and fourth embodiments of the present invention. The reinforcing ribs 50 of the first stabilizing element 10 extend from the outsole 3 along the outer layer 12 of the stabilizing element 10. The outer layer 12 of the stabilizing element 10 is integrally formed with the outsole or an outsole component. Furthermore, the reinforcing ribs 50 extend essentially along the entire length of the stabilizing element 10. The reinforcing ribs 50 further extend at least partially along the outsole 3, an embodiment also shown in FIG. 10. It should be noted that the present invention includes the following aspects.
