Description

Technical Field

[0001] This invention relates to the field of footwear, and more particularly to sole elements suitable for placement in shoes, preferably athletic shoes. Background Technology

[0002] Maximizing athlete performance is central to the development and evolution of sporting goods. This is especially true for athletic footwear, such as running shoes, where athlete performance hinges on the shoe's performance. Therefore, significant efforts have been invested in optimizing the performance of athletic footwear, particularly running shoes.

[0003] A key benchmark for evaluating shoe performance is energy return and / or propulsion. For example, a shoe's energy return and / or propulsion can be modulated by its stiffness. Specifically, increasing shoe stiffness can achieve higher energy return and / or higher propulsion.

[0004] Typically, shoes are manufactured with a predefined stiffness that cannot be adjusted after the manufacturing process, making stiffness, energy return, and / or propulsion permanent characteristics of the shoe. However, different athletes prefer different shoe stiffnesses, and when the shoe's stiffness does not match an athlete's specific preferences, the athlete's performance may decline significantly.

[0005] Therefore, new technologies are needed to change and improve the performance of shoes, especially athletic shoes, in order to at least address some of the shortcomings of the existing technologies and further improve other aspects. Summary of the Invention

[0006] A first aspect of the invention relates to a sole element suitable for placement in a shoe, preferably an athletic shoe. The sole element is a strobel board and / or insole, and includes means for reinforcing at least a portion of the sole element. Specifically, at least a portion of the sole element is located at least in an area suitable for receiving the forefoot. Furthermore, the sole element is adapted to be placed in the shoe when worn.

[0007] For example, a sole plate and / or insole may be adapted to be disposed within a shoe. Adaptation to be disposed within a shoe may include: the sole element being fixedly attached to the shoe. For example, the sole element may be disposed within the shoe as an integral part of the shoe. Specifically, the sole element may be permanently attached to at least a portion of the shoe, such as the upper and / or midsole. In particular, a sole plate may be disposed within the shoe as an integral part of the shoe. Additionally, or alternatively, adaptation to be disposed within a shoe may include: the sole element being configured such that the sole element can be accommodated by the shoe. For example, the size and / or geometry and / or thickness of the sole element may enable the shoe to accommodate the sole element. Specifically, the insole may be adapted such that the insole can be accommodated by the shoe, for example, by placing the insole inside the shoe.

[0008] The sole element includes means for reinforcing at least a portion of the sole element. The means for stiffening (hereinafter also referred to as "stiffening device") may include at least one means for reinforcing at least a portion of the sole element. The stiffening device may be adapted such that the at least portion of the sole element reinforced by the stiffening device is located in an area adapted to accommodate a forefoot. The area adapted to accommodate a forefoot may include an area that accommodates at least a portion of the forefoot when the sole element is disposed in the shoe. For example, the forefoot area may include an area associated with the toes and / or metatarsal bones of the foot.

[0009] Suitable for placement in the shoe while wearing the shoe may include: the sole element being placed in the shoe when an athlete wears the shoe to perform (sports) activities. In other words, the sole element may be suitable for placement in the shoe—at least during (typical) use of the shoe, such as during (sports) activities like walking and / or running.

[0010] Reinforcing at least a portion of the sole element—located in the area suitable for accommodating the forefoot—allows for adjustment of the forefoot stiffness of the sole element. Adjusting the forefoot stiffness of the sole element enables localized and specific adjustments to the responsiveness and / or energy return of the shoe—containing that sole element. Therefore, the forefoot stiffness and / or responsiveness of the shoe can be adapted to the athlete's needs, thereby optimizing athlete performance and enhancing shoe comfort.

[0011] Typically, a device for reinforcing at least a portion of a sole element can be adapted to reinforce at least a portion of the shoe—suitable for accommodating the forefoot. Additionally, or alternatively, a device for reinforcing at least a portion of a sole element can be adapted to reinforce at least a portion of the shoe—suitable for accommodating the midfoot. Specifically, the reinforcing device can be configured to extend from the portion of the shoe suitable for accommodating the forefoot toward the portion of the shoe suitable for accommodating the midfoot.

[0012] In some embodiments, reinforcing at least a portion of the shoe adapted to accommodate the forefoot and / or midfoot may include: increasing shoe-related propulsion. Additionally, or alternatively, reinforcing at least a portion of the shoe adapted to accommodate the forefoot and / or midfoot may include: reducing shoe-related spike pressure.

[0013] For example, the reinforcing device can be configured such that when the sole element is disposed in the shoe, the reinforcing device also reinforces the portion of the shoe—suitable for accommodating a portion of the forefoot. In other words, the reinforcing device can reinforce that portion of the sole element and that portion of the shoe. For example, the reinforcement of that portion of the shoe can be based on the reinforcement of that portion of the sole element. In particular, the portion of the sole element reinforced by the reinforcing device can include: reinforcing that portion of the shoe when the sole element is disposed in the shoe. At least a portion of the shoe reinforced by the reinforcing device can substantially correspond to: at least a portion of the sole element reinforced by the reinforcing device. Alternatively, at least a portion of the shoe reinforced by the reinforcing device can be a sub-portion of at least a portion of the sole element reinforced by the reinforcing device. Alternatively, at least a portion of the shoe reinforced by the reinforcing device can be a super-portion of at least a portion of the sole element reinforced by the reinforcing device.

[0014] Reinforcement devices can strengthen sole components and / or at least a portion of the shoe to increase shoe-related propulsion. For example, shoe-related propulsion may include shoe-related energy return. Specifically, energy return can be increased by reinforcing at least a portion of the shoe adapted to accommodate the forefoot. In particular, energy return related to the forefoot area of ​​the shoe can be increased. Increasing energy return related to the forefoot area of ​​the shoe can minimize energy loss in the shoe, thereby optimizing the performance of the athlete wearing the shoe. For example, enhancing the energy return of the portion of the shoe adapted to accommodate the forefoot may be particularly advantageous for athletes using a forefoot running posture.

[0015] Additionally, or alternatively, reinforcement devices may strengthen at least a portion of the sole element and / or the shoe to reduce shoe-related spike pressure. Reducing shoe-related spike pressure may include reducing the pressure and / or force that the spikes—based on the weight of the athlete wearing the shoe—may exert on the sole element and / or the shoe. Specifically, strengthening at least a portion of the sole element and / or the shoe allows the force—exerted by the spikes on the shoe and / or sole element and / or the foot—to be distributed over a larger area, thereby minimizing pressure (force per unit area). Therefore, strengthening at least a portion of the sole element and / or the shoe enhances the wearing comfort of the shoe containing that sole element, thereby contributing to optimized athlete performance. In particular, the reduced spike pressure and increased propulsion and / or energy return create a synergistic effect, enabling the athlete wearing the shoe to achieve optimal performance.

[0016] Typically, sole components can be disposed within the shoe such that at least a portion of the sole components is replaceable. In particular, the replaceable at least portion of the sole components may include reinforcement devices.

[0017] Placing a sole element in a shoe such that at least a portion of the sole element is replaceable may include: the at least portion of the sole element being replaceable—without substantially affecting the sole element and / or other parts of the shoe. For example, the at least portion of the sole element may not be permanently attached to other parts of the shoe and / or midsole, e.g., not attached to other parts by gluing and / or stitching. Additionally, or alternatively, placing a sole element in a shoe such that at least a portion of the sole element is replaceable may include: the at least portion of the sole element being replaceable according to the athlete's needs. Typically, the replaceable at least portion of the sole element may be located in an area suitable for receiving the forefoot. In some embodiments, the replaceable at least portion of the sole element may include substantially the sole element itself, e.g., the sole element itself may be replaceable. For example, when the sole element includes an insole, the sole element may be replaceable.

[0018] By configuring the sole elements such that at least a portion of the sole elements is replaceable, preferably as part of a reinforcement device, the stiffness of the sole elements and / or the shoe can be adjusted according to the athlete's needs. Specifically, the replaceable at least a portion of the reinforcement device can be replaced and / or substituted by different at least a portion of the reinforcement device. In other words, a first portion of the reinforcement device can be replaced and / or substituted by a second portion of the reinforcement device.

[0019] Specifically, the first and second portions of the reinforcing device may include different reinforcing properties; for example, the first portion may include a first reinforcing property, and the second portion may include a second reinforcing property. In particular, the first reinforcing properties of the first portion may cause a first stiffness in the sole element and / or the shoe. Additionally, or alternatively, the second reinforcing properties of the second portion may cause a second stiffness in the sole element and / or the shoe. For example, the second reinforcing property of the second element may be such that at least a portion of the sole element and / or the shoe including the second element is more rigid than at least a portion of the sole element and / or the shoe including the first portion.

[0020] Specifically, the replaceable at least portion of the sole component is adapted to be replaced and / or removed through an opening in the shoe. For example, the replaceable at least portion of the sole component is adapted to be replaced and / or removed through an ankle opening in the shoe.

[0021] Replacing and / or removing at least a portion of a sole component through an opening in the shoe allows for simple and quick replacement of that portion. Specifically, replacing and / or removing at least a portion of a sole component through an ankle opening allows for replacement and / or removal through the shoe's natural opening (i.e., an opening inherent to the shoe). In other words, when replacing and / or removing at least a portion of a sole component through an ankle opening, there is no need to introduce further and / or additional openings in the shoe, such as further and / or additional openings in the midsole. Therefore, the shoe manufacturing process can be simplified and accelerated. Furthermore, shoe stability can be improved because there is no need to introduce further openings (i.e., areas without material).

[0022] Typically, a reinforcing device may include a bag portion adapted to receive a reinforcing element. In particular, the bag portion may be adapted to receive the reinforcing element through an opening.

[0023] The pocket may be located in an area suitable for receiving the forefoot. The pocket may include a size and / or geometry such that it can receive a reinforcing element. Typically, the pocket may include and / or define a cavity. For example, the pocket may include a size and / or geometry such that the size and / or geometry of the cavity substantially corresponds to the size and / or geometry of the reinforcing element. The pocket may include an opening, such as an inlet to the cavity, through which the reinforcing element can be received. Specifically, the pocket may be adapted such that the opening points towards the opening of the shoe when the sole element is disposed in the shoe. In particular, the pocket may be adapted such that the opening of the pocket points towards the ankle opening of the shoe.

[0024] Furthermore, the opening in the bag portion can allow the reinforcing element to be removed from the bag portion. In other words, the bag portion can be adapted to allow the reinforcing element to be replaced. For example, the bag portion can accommodate a first reinforcing element that includes a first reinforcing characteristic. Subsequently, the first reinforcing element can be removed through the opening in the bag portion, and a second reinforcing element that includes a second reinforcing characteristic can be accommodated.

[0025] The reinforcement device, including a pocket section suitable for accommodating reinforcement elements, enables efficient and simple replacement and / or substitution of the reinforcement elements. This efficient and simple replacement and / or substitution of the reinforcement elements helps optimize the adjustment of the shoe's propulsion and / or energy return and / or spike pressure.

[0026] Specifically, the bag portion may be contained within the storage board. Alternatively, the bag portion may be at least partially attached to the storage board. In particular, the bag portion may be at least partially attached to the storage board by sewing. Alternatively, the bag portion may be at least partially attached to the storage board by knitting.

[0027] For example, the bag portion can be an integral part of the store container, such as the store container and the bag portion being one piece. For example, a first portion of the bag portion can extend from the store container, and a second portion of the bag portion can be contained within the store container. Specifically, at least a portion of the inner side of the bag portion cavity can be formed by the store container.

[0028] The pocket portion included within the storage board allows for the use of a one-piece storage board. This one-piece design enhances the stability of the pocket portion and contributes to the lifespan of the storage board. Furthermore, the pocket portion included within the storage board allows for its attachment to the storage board without seams, thus helping to optimize shoe comfort.

[0029] Additionally, or alternatively, at least a portion of the bag portion may be attached to the storage board. For example, the bag portion may be attached to the storage board such that a portion of the bag portion is formed by the storage board. Additionally, or alternatively, a separate bag portion may be attached to the storage board. In other words, a prefabricated bag portion that forms its own cavity may be attached to the storage board.

[0030] Specifically, the bag portion can be attached to the storetrap board by sewing. For example, the bag portion can be attached to the storetrap board by sewing the outer area and / or boundary area of ​​the bag portion to the storetrap board. Alternatively, the bag portion can be attached to the storetrap board by knitting. For example, the bag portion can be attached to the storetrap board by knitting the outer area and / or boundary area of ​​the bag portion to the storetrap board.

[0031] Attaching the bag portion to the storage board by sewing and / or knitting simplifies the creation of the bag portion on the storage board. Furthermore, attaching the bag portion to the storage board by sewing and / or knitting improves the quality of the attachment (e.g., attachment that is particularly resistant to external forces), thus contributing to the lifespan of the storage board.

[0032] In some embodiments, the bag portion may be disposed on the side of the storeroom that is adapted to face the inside of the shoe.

[0033] For example, the bag portion may be at least partially attached to the side of the storage board that is adapted to face the inside of the shoe. Alternatively, the bag portion may be contained within the storage board such that at least a portion of the bag portion extends from the side of the storage board that is adapted to face the inside of the shoe. For example, the bag portion may be positioned on one side of the storage board such that the opening of the bag portion is located on the side of the storage board that is adapted to face the inside of the shoe.

[0034] The side facing inwards may include: at least a portion of the twill side being covered by a component of the shoe. For example, at least a portion of the twill side may be covered by the insole. In other words, the side of the twill side suitable for facing inwards may not be directly (visually) accessible, such as through the ankle opening of the shoe, but may be covered by the insole.

[0035] The pocket is positioned on the side of the storage board that faces inwards towards the shoe, such that the opening of the pocket can be located on the same side. Positioning the opening of the pocket on this side facilitates the replacement of reinforcing elements. Specifically, positioning the opening of the pocket on this side ensures that the pocket, for example, its opening, can be directly accessed through an opening in the shoe, such as the ankle opening. Therefore, a first reinforcing element housed in the pocket can be removed from the pocket through the opening and the ankle opening of the shoe, and a second reinforcing element can be inserted into the pocket through both the ankle opening and the opening of the pocket. Thus, positioning the pocket on the side of the storage board that faces inwards towards the shoe optimizes the replaceability of parts of the reinforcing device, such as reinforcing elements.

[0036] Typically, the bag portion may include means for securing reinforcing elements. For example, means for fixing (hereinafter also referred to as "fixing means") may include hook and loop fasteners.

[0037] For example, the means for securing the reinforcing element may include means for holding the reinforcing element within the pocket portion. Specifically, the means for securing the reinforcing element may include means for at least partially closing the pocket opening. Typically, the securing means may be adapted to allow the reinforcing element to be released. In other words, the means for securing the reinforcing element may include means for reversibly securing the reinforcing element. For example, the means for securing the reinforcing element may include a hook-and-loop fastener. Additionally, or alternatively, the means for securing the reinforcing element may include at least one button, preferably a snap. At least a portion of the means for securing the reinforcing element may be disposed on the side of the storage board—suitable for facing the inside of the shoe.

[0038] Such a pocket section—including means for securing the reinforcing element (e.g., hook-and-loop fasteners for closing at least a portion of the pocket opening)—allows the reinforcing element to be secured and held in a intended and / or pre-configured position. Specifically, the means for securing the reinforcing element allows it to be held within the pocket section, ensuring that the reinforcing element remains within the area of ​​the stud plate suitable for receiving the forefoot. Therefore, when the shoe is worn, the reinforcing element remains within the pocket section, reinforcing the stud plate and / or the area of ​​the shoe suitable for receiving the forefoot, thereby maximizing the shoe's energy return, minimizing shoe-related spike stress, and optimizing the performance of the athlete wearing the shoe.

[0039] Typically, a reinforcing device may include a reinforcing sheet.

[0040] The reinforcing sheet may include a length in a first direction that is substantially less than its length in a second direction. For example, the thickness associated with the reinforcing sheet may be substantially less than its planar extension. Specifically, the reinforcing sheet may include a continuous and / or connected sheet. The reinforcing sheet may include at least one notch. Additionally, or alternatively, the reinforcing sheet may include at least one opening.

[0041] Typically, the reinforcing strip is adapted to be housed within the pouch of the store container. For example, the size and / or shape of the reinforcing strip can be configured such that it can be accommodated within the pouch.

[0042] The reinforcement device, including the reinforcing plate, can reinforce the liner and / or the shoe—through elements with a small thickness—thereby minimizing—changes in the shape of the liner—when the reinforcing plate is placed inside the pocket. Specifically, using the reinforcing plate can minimize—the formation of bulges within the liner and / or deformation of the liner—when the reinforcing plate is placed inside the pocket. Minimizing the formation of bulges within the liner and / or deformation of the liner helps optimize the wearing comfort of the shoe.

[0043] In some embodiments, the reinforcing device may include a reinforcing element at least partially attached to the conduit board. Specifically, the reinforcing device may include a reinforcing element at least partially attached to the conduit board by gluing. Alternatively, the reinforcing device may include a reinforcing element at least partially attached to the conduit board by sewing.

[0044] For example, a reinforcing element may be attached to the conduit board at its boundaries and / or outer regions. Specifically, at least a portion of the boundaries and / or outer regions of the reinforcing element may be sewn and / or stitched to the conduit board. More specifically, the reinforcing element may be adapted such that at least a portion of its boundaries and / or outer regions follow a portion of the boundaries and / or outer regions of the conduit board. In other words, a portion of the boundaries and / or outer regions of the reinforcing element may be sewn and / or stitched to a portion of the boundaries and / or outer regions of the conduit board. Additionally, or alternatively, at least a portion of the reinforcing element may be attached to the conduit board by gluing. For example, gluing a portion of the reinforcing element to the conduit board may include gluing at least a central and / or intermediate portion of the reinforcing element to the conduit board. In some embodiments, the reinforcing element may be glued to the conduit board substantially over its entire surface facing the conduit board.

[0045] Attaching the reinforcing element at least partially to the stowage board by gluing and / or sewing facilitates the attachment of the reinforcing element while ensuring a stable attachment, such as an attachment that can resist external forces.

[0046] Typically, reinforcing elements and / or reinforcing sheets may include at least one opening. For example, reinforcing elements and / or reinforcing sheets may include at least two, preferably at least three, and most preferably at least four openings. Specifically, the at least one opening may include an elliptical geometry. For example, the major semi-axis of the elliptical geometry may be substantially parallel to the elongation direction of the board and / or shoe. Typically, reinforcing elements and / or reinforcing sheets may include a rib-like structure. For example, at least one opening of a reinforcing element and / or reinforcing sheet may be separated by at least one rib. For example, reinforcing elements and / or reinforcing sheets may include at least one, preferably at least two, and most preferably at least three ribs. Additionally, or alternatively, reinforcing elements and / or reinforcing sheets may include a grid and / or cell structure.

[0047] The reinforcing element and / or reinforcing piece having at least one opening, preferably arranged in a rib-like and / or grid-like and / or cell-like structure, allows for sufficient reinforcement of the stud board and the shoe containing the stud board, while minimizing the weight of the reinforcing element and / or reinforcing piece.

[0048] Additionally, or alternatively, the reinforcing element and / or reinforcing plate may include at least one finger-like portion. For example, the reinforcing element and / or reinforcing plate may be adapted such that the at least one finger-like portion extends to the medial (i.e., inner side of the foot) forefoot portion of the container. In particular, the at least one finger-like portion of the reinforcing element and / or reinforcing plate may extend to the medial forefoot portion of the container such that the at least one finger-like portion is located in the region of the container—associated with the big toe of the foot. Additionally, or alternatively, the reinforcing element and / or reinforcing plate may be adapted such that the at least one finger-like portion extends to the lateral (i.e., outer side of the foot) and / or central midfoot portion of the container. Typically, the length of the at least one finger-like portion may be at least 0.5 cm, preferably at least 1 cm, more preferably at least 1.5 cm, even more preferably at least 2 cm, and most preferably at least 2.5 cm.

[0049] Typically, at least a portion of the reinforcing device can be injected into the stash board.

[0050] For example, injecting at least a portion of the reinforcing device into the conduit board may include injecting at least a portion of the reinforcing device into a prefabricated conduit board. For example, the at least a portion of the reinforcing device may be injected into the conduit board to form an inner bottom plate. Specifically, injecting at least a portion of the reinforcing device into the conduit board may include: arranging textiles—e.g., the conduit board—in a mold. For example, the textiles may include non-combustible materials. In particular, the non-combustible material may include non-woven materials. Injecting at least a portion of the reinforcing device into the conduit board may also include: injecting and / or injecting material onto the textiles, for example, into and / or injecting it onto the conduit board. For example, the material may be injected and / or injected onto a non-woven material. Specifically, the material may be injected into the textiles such that the material at least partially penetrates into the textiles, for example, the non-woven material. Typically, the (injected) material may include polyamide. Additionally, or alternatively, the (injected) material may include thermoplastic elastomers. For example, the thermoplastic elastomer may include polyether block amides.

[0051] Typically, at least a portion of the reinforcing device is injected into the shoe plate such that it is located in the forefoot region. Alternatively, the reinforcing device may be injected into the shoe plate such that at least a portion is located in the midfoot region. For example, the reinforcing device may be injected into the shoe plate such that at least a portion extends from the forefoot portion to the midfoot region. Injecting the reinforcing device into the midfoot region provides midfoot stiffness, thereby improving propulsion and / or energy return, and thus optimizing athlete performance. Furthermore, injecting the reinforcing device into the shoe plate such that it extends from the forefoot portion to the midfoot portion allows for simultaneous reinforcement of both the forefoot and midfoot portions. Providing both forefoot and midfoot stiffness simultaneously maximizes propulsion and / or energy return, thereby optimizing athlete performance.

[0052] Additionally, or alternatively, at least a portion of the reinforcing device may be cast and / or poured onto the conduit board. For example, the reinforcing device may be cast and / or poured onto the side of the conduit board suitable for receiving the foot. Additionally, or alternatively, the reinforcing device may be cast and / or poured onto the side of the conduit board opposite to the side suitable for receiving the foot. Specifically, casting and / or pouring the reinforcing device onto the conduit board may include: casting and / or pouring material onto the conduit board. For example, the material may include polyurethane.

[0053] Typically, a storage board may contain nonwoven materials. Additionally, or alternatively, a storage board may contain knitted materials. For example, a storage board may be a knitted storage board. In some embodiments, a storage board may contain woven materials. Typically, a storage board may contain non-flammable materials. Additionally, or alternatively, a storage board may contain materials with limited stretchability. For example, a storage board may contain substantially non-stretchable materials. For example, a storage board containing materials with limited stretchability facilitates the application of storage board stitching, such as sewing the storage board to a shoe.

[0054] Typically, a reinforcing device may be attached to and / or injected into the confectionery board such that the boundary of the reinforcing device is spaced apart from the boundary of the confectionery board. Spaced apart from the boundary of the reinforcing device may include: the boundary of the reinforcing device being spaced apart from the boundary of the confectionery board by a certain distance. Specifically, the boundary of the reinforcing device may be spaced apart from the boundary of the confectionery board such that the distance between the boundary of the reinforcing device and the boundary of the confectionery board—along the boundary of the reinforcing device and / or the boundary of the confectionery board—is substantially uniform.

[0055] For example, the distance between the boundary of the reinforcing device and the boundary of the conduit board can be at least 5 mm, preferably at least 10 mm, more preferably at least 15 mm, more preferably at least 20 mm, and most preferably at least 25 mm. Additionally, or alternatively, the distance between the boundary of the reinforcing device and the boundary of the conduit board can be at most 10 cm, preferably at most 8 cm, more preferably at most 6 cm, even more preferably at most 4 cm, and most preferably at most 2 cm. In some embodiments, the distance between the boundary of the reinforcing device and the boundary of the conduit board can be at most 1.5 cm, preferably at most 1 cm, more preferably at most 0.8 cm, even more preferably at most 0.6 cm, and most preferably at most 0.4 cm.

[0056] Typically, the shape and / or size of the reinforcing device can be adapted to rescale substantially to a portion of the shape and / or size of the confectionery board. For example, the shape and / or size of the reinforcing device can be adapted to rescale substantially to a portion of the front foot of the confectionery board. Additionally, or alternatively, the shape and / or size of the reinforcing device can be adapted to rescale substantially to a portion of the middle foot of the confectionery board. For example, the shape and / or size of the reinforcing device can be rescaled to space the boundary of the reinforcing device from the boundary of the confectionery board. For example, the shape and / or size of the reinforcing device may include a rescaling of at least 0.8 times, preferably at least 0.85 times, more preferably at least 0.9 times, even more preferably at least 0.92 times, and most preferably at least 0.95 times, of the shape and / or size of a portion of the confectionery board.

[0057] In some embodiments, the reinforcement device may be at least partially attached to the insole of the shoe. In particular, the reinforcement device may be attached to the side of the insole that faces the shoe's midsole. Additionally, or alternatively, the reinforcement device may be attached to the side of the insole that faces the shoe's midsole.

[0058] For example, the side of the insole suitable for facing the midsole of the shoe may include the side of the insole opposite to the side suitable for facing the midsole of the shoe. Specifically, the reinforcement device may be injected into the insole of the shoe. Furthermore, the reinforcement device may be bonded and / or glued to the insole of the shoe. For example, the insole of the shoe may include an insole. In particular, the reinforcement device may be injected and / or bonded and / or glued to the insole, such that the reinforcement device is positioned on the side of the insole suitable for facing the midsole of the shoe.

[0059] Specifically, the reinforcement device may be attached to and / or injected into a portion of the insole, such as the midfoot portion and / or the forefoot portion of the insole. Typically, a region may be associated with the reinforcement device. For example, the region associated with the reinforcement device may include: the area of ​​the insole portion to which the reinforcement device is attached, and / or the area of ​​the insole portion to which the reinforcement device is injected. Specifically, the region associated with the reinforcement device may be at least 40%, preferably at least 50%, more preferably at least 60%, even more preferably at least 70%, and most preferably at least 80% of the corresponding area of ​​the insole. For example, the corresponding area of ​​the insole, such as the insole area corresponding to the area of ​​the reinforcement device, may include a portion of the insole that surrounds and / or encloses the reinforcement device. In particular, the portion of the insole surrounding and / or enclosing the reinforcement device may—from the starting point to the ending point of the reinforcement device—surround and / or enclose the reinforcement device. In some embodiments, the starting point of the reinforcement device may be located in the forefoot portion of the insole. Furthermore, the ending point of the reinforcement device may be located in the midfoot and / or heel area of ​​the insole.

[0060] For example, a shoe, such as an athletic shoe, may be associated with at least two insoles. For example, a first insole may be associated with a first stiffness, and a second insole may be associated with a second stiffness. Specifically, the insoles and / or the shoe may be adapted to make the insoles interchangeable. For example, the shoe may initially include a first insole, which may be disposed within a cavity of the shoe. The first insole may then be removed from the shoe, for example, through an ankle opening. After the first insole is removed from the shoe, a second insole may be inserted into a cavity of the shoe, for example, through an ankle opening. Typically, a first reinforcement device may be attached to and / or injected into the first insole. The first reinforcement device may be attached to and / or injected into the side of the first insole—suitable for facing the midsole of the shoe. For example, the first reinforcement device may be adapted to increase the stiffness and / or propulsion of the shoe—for example, a shoe including the first insole. Furthermore, the second insole may not include any means for reinforcing the insole; for example, no additional material for reinforcing the insole is attached to and / or injected into the second insole. In other words, the stiffness associated with the second insole corresponds to the stiffness of a typical, for example, unreinforced insole.

[0061] Associating a shoe, such as an athletic shoe, with at least two (interchangeable) insoles, such as insoles with different stiffnesses, allows the shoe's stiffness to be adapted to the athlete's specific and individual needs. For example, in the first case—when a flexible (low-stiffness) and cushioned shoe is preferred—the athlete can choose from at least two insoles that are associated with low stiffness and / or have no additional reinforcement.

[0062] A second aspect of the invention relates to a shoe, preferably an athletic shoe. The shoe includes a sole element according to any of the above embodiments. Attached Figure Description
