[0069] The indefinite articles "a", "an" and "the" include plural referents unless clearly contradicted or the context clearly dictates otherwise.

[0070] The term "comprising" is an open transitional phrase. The list of elements following the transitional phrase "comprising" is a non-exclusive list, such that elements other than those specifically recited in the list may be present. The phrase "consisting essentially of limits the composition of a component to the specified materials and those materials that do not materially affect the basic and novel properties of the component. The phrase "consisting of limits the composition of a component to the specified materials and excludes any unspecified materials.

[0071] When a numerical range including an upper limit and a lower limit is cited herein, unless otherwise specified in a specific case, the range is intended to include its endpoints, as well as all integers and fractions within the range. When defining a range, the disclosure or claims are not intended to be limited to the specific values ​​cited. In addition, when quantity, concentration or other values ​​or parameters are given as a range, one or more ranges, or as a list of upper and lower limits, this should be understood to specifically disclose all ranges formed by any pair of any range upper limit or value and any range lower limit or value, regardless of whether these pairs are disclosed separately.

[0072] The outsole according to an embodiment of the present application is designed to provide various advantageous effects for the wearer. The outsole can promote the optimal athletic performance of the wearer participating in sports (e.g., football), while also providing comfortable footwear. The outsole is designed to provide stiffness in specific areas and flexibility in other areas. The combination of stiffness and flexibility can promote the desired sports performance while also providing comfort. The outsole according to an embodiment of the present application is designed to at least partially solve and / or pursue the following problems and / or goals.

[0073] The outsole of a shoe (e.g., a soccer shoe) optimized for fast running (i.e., sprinting) may exhibit rigid material behavior, which may cause significant damage to the wearer. Exemplarily, a rigid outsole may reduce the comfort of the wearer. In addition, due to the reduced overall flexibility of the shoe, a rigid outsole may reduce ball feel. In addition, due to limited metatarsal and / or toe flexion, an outsole that exhibits linear and / or uniform rigid behavior may inhibit the wearer's ability to accelerate effectively. This is very disadvantageous at a sprint start, where more toe flexion is considered beneficial. An outsole according to an embodiment of the present disclosure may allow fast running, i.e., sprinting, and at least partially avoid the above-mentioned disadvantages.

[0074] Many sports, such as soccer and / or American football, require multiple sprints during a game. Sprint starts on a flat surface that may be covered in grass can prove difficult, even with spikes, because there is no external object to push off from - unlike sprinting in track and field sports, where starting blocks are typically provided. An outsole according to embodiments of the present disclosure can be provided for a shoe that can improve the start of a sprint, i.e., allow for a better push off.

[0075] Shoes such as soccer shoes typically have relatively flat and / or rigid outsoles, which make it difficult or at least not easy for the foot to roll during walking and / or moderate running and / or acceleration. However, it is also known that curved outsoles may lead to instability and / or limited ground contact. This is generally unacceptable for sports such as soccer, rugby, etc. The outsole according to an embodiment of the present disclosure can provide an outsole that allows improved walking and / or moderate running and / or acceleration, while at least partially avoiding instability and / or limited ground contact.

[0076] Outsoles that include cushioning elements typically do not allow for the adaptation of the properties provided by the cushioning elements (e.g., compressibility and / or cushioning) without changing the cushioning elements themselves. Therefore, the adaptation of the cushioning elements (e.g., by changing the material) typically involves considerable effort. Outsoles according to embodiments of the present disclosure may at least partially overcome this drawback.

[0077] The outsole according to an embodiment of the present disclosure comprises a first sole section, which comprises at least one spike and is arranged at least in a midfoot portion of the outsole. In addition, the outsole comprises a second sole section, which comprises at least one spike and is arranged at least in a toe portion of the outsole, wherein the first sole section and the second sole section partially overlap. In addition, the outsole comprises a first cushioning element arranged between the first sole section and the second sole section, wherein the first cushioning element overlaps with at least one first spike of the first or second sole section. In addition, the outsole comprises a second cushioning element arranged between the first sole section and the second sole section, wherein the second cushioning element overlaps with at least one second spike of the first or second sole section.

[0078] In some embodiments, the first sole section and / or the second sole section may include multiple layers. Exemplarily, the first sole section and / or the second sole section may include multiple carbon fiber layers and / or glass fiber layers embedded in a polymer matrix. However, the first sole section and / or the second sole section may also be a single layer each. The first sole section and / or the second sole section do not have to be a closed layer, but may also have a grid-like and / or frame-like structure. The grid-like and / or frame-like structure may be particularly advantageous for reducing the weight of the outsole. In some embodiments, the first sole section and / or the second sole section may include a polymer, such as polyamide 11 (PA 11) and / or polyamide 12 (PA 12). In some embodiments, the first sole section and / or the second sole section may include a thermoplastic elastomer (TPE), such as polyether block amide (PEBA) and / or thermoplastic polyurethane (TPU). In some embodiments, the first sole section and / or the second sole section may be formed at least partially by injection molding. Exemplarily, a layer may be molded, or a grid-like and / or frame-like support structure may be overmolded. In addition, composite materials, such as carbon fiber reinforced polymers, glass fiber reinforced polymers, and / or other reinforcing materials, may be included in the first sole section and / or the second sole section. In some embodiments, the first sole section and / or the second sole section may be formed at least in part by an additive manufacturing method (e.g., a 3D printing method) and / or a composite processing method. In some embodiments, the material of the first sole section and / or the second sole section may have a stiffness in the toe portion that is less than that in the midfoot portion.

[0079] As described herein, components (e.g., a first sole section and a second sole section) that are co-formed by injection molding, overmolding, or other similar co-molding manufacturing processes are integrally formed components. As a result of the co-molding process used to manufacture the components, the integrally formed components are integrally connected.

[0080] According to the embodiment of the present disclosure, the studs may also be referred to as cleats, which can be used to provide traction for the wearer on soft ground (e.g., grass). The use of studs is known in the field of football, i.e., soccer, American football, rugby and / or track and field. In some embodiments, the studs may be formed integrally with the first sole section and / or the second sole section. In some embodiments, the studs may be injected at least partially (e.g., the tips of the studs) onto the base material. In some embodiments, the base material may be injected at least partially onto the tips of the studs. In such embodiments, the prefabricated tips of the studs are placed in a mold and over-injected with the base material. The base material may include the first sole section and / or the second sole section. In some embodiments, the studs may include TPU. The integrally formed or injected studs eliminate the need to screw on the studs and / or replace the studs. However, interchangeable studs or screw-on studs may also be used. In such embodiments, studs of different lengths and / or materials may be used for different ground conditions.

[0081] The midfoot portion of the outsole may be referred to as the portion of the outsole that is configured to at least partially support the metatarsals of the wearer. The toe portion of the outsole may be referred to as the portion of the outsole that is configured to at least partially support the toes of the wearer. Generally, it should be understood that the wearer's midfoot may be separated from the toe portion at the metatarsophalangeal joint. Therefore, it should be understood that the metatarsophalangeal joint may be considered to be part of the forefoot, but not part of the midfoot.

[0082] Since the first sole section and the second sole section partially overlap, it will be appreciated that these sections cannot be completely superimposed. Therefore, weight can be saved. Furthermore, since the first sole section and the second sole section each include at least one spike, it will be appreciated that they are preferably both configured to engage the ground.

[0083] In some embodiments, the first sole segment and the second sole segment partially overlap such that a portion of the first sole segment is disposed over a portion of the second sole segment. In some embodiments, the first sole segment and the second sole segment partially overlap such that a portion of the second sole segment is disposed over a portion of the first sole segment. Unless otherwise specified, a component that is described as being "disposed on" another component is located above the other component in a vertical direction relative to a ground-facing surface of the outsole.

[0084] Furthermore, by means of the overlapping area, i.e. the area where the first sole section and the second sole section overlap, a target property setting can be achieved. For example, the stiffness of the outsole and / or the support of the foot can be increased in the overlapping area. Optionally, the first sole section partially overlaps the second sole section and / or the second sole section partially overlaps the first sole section. Thus, the overlapping area can be further selectively engineered.

[0085] The first sole section and the second sole section may at least partially not overlap in one or more areas of the outsole. In particular, the first sole section and the second sole section may at least partially not overlap in a first area of ​​the outsole that supports the wearer's toes. As a result, toe flexion may be enhanced, which is advantageous during a sprint start, where more toe flexion is beneficial. Further in particular, the second sole section may include a softer material than the first sole section, i.e. a less rigid material, in order to achieve a better feel for the ball and / or toe flexion, while still providing sufficient support in the midfoot area.

[0086] The first cushioning element and / or the second cushioning element, i.e., one / multiple cushioning elements, can be attached to the first sole section and / or the second sole section, for example, by gluing, welding, secondary molding and / or stitching. The cushioning element may include at least one cushion pad and / or at least one spring element. Since the first cushioning element and the second cushioning element are arranged between the first sole section and the second sole section, it should be understood that the cushioning element may be arranged at least partially in the above-mentioned overlapping area. One / multiple cushioning elements may include substantially elastic material behavior. Therefore, one / multiple cushioning elements may allow improved energy to be returned to the wearer. In some embodiments, one / multiple cushioning elements may also be viscoelastic, i.e., exhibit both viscous and elastic behavior. This allows one / multiple cushioning elements to be suitable for typical load patterns of certain sports. Exemplarily, when walking, i.e., at low load speeds, one / multiple soft cushioning elements may be required, while when sprinting, i.e., at high load speeds, one / multiple hard cushioning elements may be required.

[0087] The first cushioning element and / or the second cushioning element may provide various advantages and / or perform different tasks.

[0088] First, the first cushioning element and / or the second cushioning element can be used to separate the first sole section and / or the second sole section from each other so that the second area moment of the outsole can be increased. Thus, the stiffness of the outsole can be increased in the area where the first cushioning element and / or the second cushioning element is located. Since the one / multiple cushioning elements may include a lighter material than the first sole section and / or the second sole section, the stiffness can be increased with almost no additional weight.

[0089] Second, the cushioning element(s) may be used to cushion a portion of the wearer's foot, thereby increasing comfort. In particular, since the first cushioning element and the second cushioning element overlap at least one spike, respectively, they may avoid transmitting uncomfortable pressure from the spike to the wearer's foot. Thus, the first sole section and / or the second sole section may be made thinner, thereby reducing weight without reducing comfort.

[0090] Thirdly, the first cushioning element and / or the second cushioning element can act as an "integrated starting block" for the wearer, which can improve the start of a sprint, i.e. allow a better push-off. This is because the first cushioning element and the second cushioning element space the first sole section and the second sole section apart, so that a ridge can be formed, for example, on the ground-facing surface of the outsole, which allows a better push-off.

[0091] Fourth, the first cushioning element and / or the second cushioning element can provide a "rocker effect" for the outsole. Rocking outsole designs are known for medical purposes, such as for reducing forefoot plantar pressure in diabetics, but are also used to increase the comfort of casual shoes. However, the "rocker effect" may be particularly advantageous for outsoles with improved running characteristics, such as the outsoles of soccer shoes. As described in the previous paragraph, the first cushioning element and / or the second cushioning element separate the first sole section and the second sole section so that a ridge can be formed, especially on the ground-facing surface of the outsole. As a result, a portion of the running surface of the outsole can be raised so that a rolling effect, i.e., a "rocker effect", is produced. This has a positive effect on performance because during walking and / or moderate running and / or acceleration, the wearer must exert less force to overcome the pivot point, i.e., to roll the foot. The "rocker effect" produced by the first cushioning element and / or the second cushioning element may be particularly advantageous for wearers accelerating from a basic standing position. When accelerating from a standing position, the ‘rocking effect’ can particularly help to positively impact performance by reducing the force required to accelerate, therefore increasing the wearer’s acceleration.

[0092] It is understood that the first cushioning element and / or the second cushioning element used as an "integrated starting block" can simultaneously provide a "rocking effect" to the outsole. In addition, since the first cushioning element and / or the second cushioning element can be used as an "integrated starting block" and / or provide a "rocking effect", their compression characteristics can allow the adverse effects caused by the bulging of the outsole, i.e., instability, to be avoided under high load and / or vertical load conditions, such as during sprinting.

[0093] In some embodiments, the first sole section and / or the second sole section may include at least one hole that at least partially overlaps the first cushioning element or the second cushioning element. The at least one hole can be used to adjust the stiffness of the corresponding sole section. In addition, the at least one hole can also be used to adjust the compression characteristics of the cushioning element overlapping with the hole. It should be understood that the at least one hole in the first sole section and / or the second sole section does not necessarily require a closed profile in the first sole section or the second sole section. On the contrary, illustratively, the incision in the first sole section can be limited by the second sole section so that at least one hole is formed.

[0094] However, the at least one hole may comprise a closed contour in the first sole section or in the second sole section. Thereby, the stability of the at least one hole may be increased. The at least one hole may be a cut-out opening. In some embodiments, the at least one hole may be an integrally formed opening, for example by injection molding. The at least one hole is optionally provided in a sole section to which the at least one first spike and / or the at least one second spike are attached.

[0095] In some embodiments, the at least one hole may include at least one bottom hole, which may be adapted to expose the first cushioning element and / or the second cushioning element towards a surface on which the outsole will rest during normal use. The at least one bottom hole may be used to locally reduce and / or adjust the stiffness of the outsole, i.e. the stiffness of the corresponding sole section. This may be advantageous because an overlap of the first sole section and the second sole section may result in a jump in stiffness, which jump may be at least partially compensated and / or adjusted by the at least one bottom hole.

[0096] As used herein, when referring to a cushioning element in the context of an element's relationship to an aperture, the phrases "exposed," "exposed toward a surface or component," or "exposed in a direction of" means that the cushioning element is capable of deforming into the aperture toward the specified surface or component or in a specified direction. In some embodiments, when referring to a cushioning element in the context of an element's relationship to an aperture, the phrases "exposed toward a surface or component" or "exposed in a direction of" also mean that the cushioning element is visible through the aperture when viewed from the specified surface or component or in the specified direction.

[0097] In some embodiments, at least one hole may include at least one side hole, which may be suitable for exposing the first cushioning element and / or the second cushioning element in the lateral direction of the outsole or in the medial direction of the outsole. At least one side hole allows the compressibility of the cushioning element overlapping with the hole to be adjusted. In particular, at least one side hole may allow the vertical compressibility of the corresponding cushioning element to be adjusted. This is because the vertical compression of the corresponding cushioning element is at least partially not limited by the material of the corresponding sole section. On the contrary, a substantially free compression of the corresponding cushioning element is possible until the corresponding side hole is closed. In this regard, the term "vertical" refers to a direction perpendicular to the following surface, on which the outsole is placed during normal use.

[0098] In some embodiments, the at least one aperture may include at least one first aperture that at least partially overlaps the first cushioning element. Thus, the properties provided by the first cushioning element may be individually tuned.

[0099] In some embodiments, the at least one aperture may include at least one second aperture, the at least one second aperture at least partially overlapping the second cushioning element. Thus, the properties provided by the second cushioning element may be individually tuned.

[0100] It will be appreciated that at least one first hole and / or at least one second hole may be configured as a hole as described above. In addition, it will also be appreciated that at least one first hole and / or at least one second hole may provide the advantages of at least one hole as described above.

[0101] In some embodiments, the first cushioning element and / or the second cushioning element preferably do not substantially extend beyond the area of ​​the outsole configured to support the metatarsal fat pad, as viewed from the heel portion of the outsole. In such an embodiment, since the first cushioning element and / or the second cushioning element in the area may not increase the second area moment of the outsole, an increase in the stiffness of the outsole outside the area is avoided. Therefore, toe flexion can be enhanced, which is advantageous during a sprint start, where more toe flexion is beneficial. The term "substantially" may refer to the aspect that the first cushioning element and / or the second cushioning element do not extend beyond the area of ​​the outsole configured to support the metatarsal fat pad, as viewed from the heel portion of the outsole, by more than 1 cm, and optionally by more than 0.5 cm.

[0102] In some embodiments, the minimum distance between the forward point of the outsole and the forward point of the first and / or second cushioning elements may be between 10% and 35% of the length of the outsole. In some preferred embodiments, the minimum distance between the forward point of the outsole and the forward point of the first and / or second cushioning elements may be between 15% and 30% of the length of the outsole. In some preferred embodiments, the minimum distance between the forward point of the outsole and the forward point of the first and / or second cushioning elements may be between 20% and 25% of the length of the outsole. For such embodiments, the minimum distance may be measured between the forward point of the outsole and the point of the first and / or second cushioning elements that is closest to the forward point of the outsole. Unless otherwise stated, the minimum distance between the forward point of the outsole and the forward point of the first and / or second cushioning elements is measured on a straight line that is perpendicular to a line tangent to the forward point of the outsole and a line tangent to the forward point of the first and / or second cushioning elements, for example, Fig. 22 The distance is 90 as shown.

[0103] In some embodiments, the first sole section may extend beyond a region of the outsole, seen from the heel portion, which region is configured to support the metatarsal fat pad in the direction of the toe portion, which region has a reduced cross-section relative to the cross-section in a region where the first sole section overlaps the first cushioning element and / or the second cushioning element. By extending the first sole section beyond said region, abrupt changes in stiffness, which could have a negative impact on comfort and / or functionality, may be prevented. Instead, a continuous reduction in stiffness is achieved.

[0104] In some embodiments, at least one first spike and at least one second spike may be attached to the first sole section. By this, an improvement in the sprint start may be achieved. This is because the transmission of forces may be improved, since the first sole section is arranged at least in the midfoot portion of the outsole, in which high forces are exerted during the sprint start. The transmission of forces may be particularly improved when the first sole section at least partially supports a region of the outsole that is configured to support the metatarsal fat pad. This improvement in the transmission of forces may be achieved, since this region is the region through which the greatest forces are transmitted during normal use of the outsole. Furthermore, the first sole section may extend from the heel portion. Thus, instabilities between the midfoot portion and the heel portion are avoided, which in turn further contributes to an improvement in the sprint start.

[0105] The first cushioning element and / or the second cushioning element may include a thickness in the range of 1 mm to 10 mm. In some preferred embodiments, the first cushioning element and / or the second cushioning element may include a thickness in the range of 2 mm to 6 mm. These thicknesses have proven to be beneficial because they substantially improve cushioning and / or increase stiffness without adding too much material, i.e., weight, to the outsole. In addition, these thicknesses allow the first cushioning element and / or the second cushioning element to be used as an "integrated starting block" for the wearer, which enables improved sprint starts, i.e., allows better push-off without causing instability due to the wearer being lifted too far off the ground. Further, these thicknesses have proven to be sufficient to provide the above-mentioned "rocking effect" without hindering ball feel.

[0106] In some embodiments, the first cushioning element may overlap with two first spikes and / or the second cushioning element may overlap with two second spikes. In some preferred embodiments, the first cushioning element overlaps with exactly two first spikes and / or the second cushioning element overlaps with exactly two second spikes. In some preferred embodiments, at least one bottom hole as described above extends at least partially between the two first spikes or between the two second spikes. This arrangement of at least one bottom hole may be advantageous because two spikes per cushioning element have been shown to provide sufficient traction friction so that the cushioning element can be used as an integrated starting block for the wearer, which enables an improved start for a sprint.

[0107] In some embodiments, the first cushioning element may be arranged on the medial portion of the outsole, and the second cushioning element may be arranged on the lateral portion of the outsole, wherein the minimum distance between the first cushioning element and the second cushioning element is in the range of 3 mm to 50 mm, including sub-ranges. For example, in some embodiments, the minimum distance between the first cushioning element and the second cushioning element may be in the following ranges: 3 mm to 45 mm, 3 mm to 40 mm, 3 mm to 30 mm, 3 mm to 25 mm, 3 mm to 15 mm, 5 mm to 50 mm, 10 mm to 50 mm, 15 mm to 50 mm, 25 mm to 50 mm, 30 mm to 50 mm, or 40 mm to 50 mm. In some preferred embodiments, the minimum distance between the first cushioning element and the second cushioning element is in the range of 5 mm to 40 mm. In some preferred embodiments, the minimum distance between the first cushioning element and the second cushioning element is in the range of 10 mm to 30 mm. In some preferred embodiments, the minimum distance between the first cushioning element and the second cushioning element is in the range of 15 mm to 25 mm. By means of the arrangement of the first and second cushioning elements, the lateral and medial sides of the wearer's foot can be supported separately, which can increase stability. Furthermore, by means of the minimum distance between the first and second cushioning elements, it can be avoided that deformation of one cushioning element affects the other cushioning element. It has been found that this even further increases the stability provided by the outsole, in particular during fast running (e.g. sprinting).

[0108] As used above, the term "minimum distance" is the minimum distance between two cushioning elements, measured from the respective innermost points of the inner edges of the cushioning elements, for example, from the innermost point of the lateral edge of the medial cushioning element to the innermost point of the medial edge of the lateral cushioning element.

[0109] In some embodiments, the first cushioning element and / or the second cushioning element may be at least partially arranged in the midfoot portion, wherein preferably the first sole section and the second sole section overlap in the midfoot portion, wherein further preferably the first sole section and the second sole section overlap in the toe portion. By means of this configuration, a ridge may be formed in the midfoot portion (e.g. on the surface of the outsole facing the ground), which allows for a better push-off. Thus, the ridge may serve as an "integrated starting block" for the wearer. Thus, the outsole may allow for an improved start for a sprint.

[0110] In some embodiments, the first cushioning element and / or the second cushioning element may include a foam material. Foam materials have been shown to be beneficial because they allow a compromise between damping (i.e., comfort) and elasticity (i.e., energy recovery). Foam materials may include polyamides, polyether block amides, expanded polyether block amides, thermoplastic polyurethanes, expanded thermoplastic polyurethanes, ethylene vinyl acetate (EVA) and / or thermoplastic copolyesters. In addition, foam materials may be manufactured by specific processes to obtain favorable properties. Exemplarily, the use of particle foams has been shown to be advantageous in the sporting goods industry, as exemplarily described in US2014 / 366405A1 and US2018 / 035755A1. Thus, dense polymer particles are foamed to form expanded foam beads. These beads are then combined together at their surfaces by applying heat that at least partially melts the surface of the particles. For example, steam box molding and / or radio frequency fusion may be applied. Other specific process adjustments are also advantageous. For example, the gaseous foaming agent in the autoclave / extrusion / injection molding method may be replaced by a foaming agent in a supercritical state. In some embodiments, the first cushioning element and / or the second cushioning element may include a body (eg, a foam body or a 3D printed body) and a cover or coating disposed on the body to protect the body from dust and / or damage.

[0111] In some embodiments, the first cushioning element and / or the second cushioning element may include a 3D printed component, for example, a 3D printed lattice structure. 3D printed components have proven to be advantageous because they can produce anisotropic material behavior, such that the properties of the outsole can be specifically adjusted depending on the direction. In addition, the 3D printed lattice structure allows visual inspection due to the lattice structure, such that material failures in the cushioning element can be more easily identified.

[0112] In some embodiments, the first cushioning element and / or the second cushioning element may include a material having a strain rate dependent material behavior. This allows the cushioning element / elements to be adapted to the typical load patterns of certain sports. For example, it may be desirable that when walking, i.e. at low load speeds and low strain rates, a soft cushioning element / elements are desired, while when starting to sprint, i.e. at high load speeds and high strain rates, a hard cushioning element / elements are desired.

[0113] In some embodiments, a first cushioning element (e.g., a medial cushioning element) may include a higher compressibility than a second cushioning element (e.g., a lateral cushioning element). In some embodiments, a first cushioning element (e.g., a medial cushioning element) may include a first compressibility characterized by a first height change when a force is applied thereto in a vertical direction. The first height change is defined as the difference between the height of the first cushioning element in an uncompressed (assembled) state (i.e., the distance between the top surface and the bottom surface) and the height of the first cushioning element in a compressed state under a defined force. In some embodiments, a second cushioning element (e.g., a lateral cushioning element) may correspondingly include a second compressibility characterized by a second height change when the same defined force is applied to the second cushioning element in a vertical direction. The second height change is defined as the difference between the height of the second cushioning element in an uncompressed (assembled) state (i.e., the distance between the top surface and the bottom surface) and the height of the second cushioning element in a compressed state under a defined force. In such embodiments, the second height change is less than the first height change. In some embodiments, the second height change is less than or equal to 95% of the first height change. In some embodiments, the second height change is less than or equal to 80% of the first height change. In some embodiments, the second height variation is less than or equal to 60% of the first height variation. In some embodiments, the second height variation is less than or equal to 30% of the first height variation. In some embodiments, the second height variation is less than or equal to 10% of the first height variation.

[0114] In some embodiments, the second cushioning element (e.g., the lateral cushioning element) may include a higher compressibility than the first cushioning element (e.g., the medial cushioning element). In some embodiments, the second cushioning element (e.g., the lateral cushioning element) may include a first compressibility characterized by a first height change when a force is applied thereto in a vertical direction. The first height change is defined as the difference between the height of the second cushioning element in an uncompressed (assembled) state (i.e., the distance between the top surface and the bottom surface) and the height of the second cushioning element in a compressed state under a defined force. In some embodiments, the first cushioning element (e.g., the medial cushioning element) may correspondingly include a second compressibility characterized by a second height change when the same defined force is applied to the first cushioning element in a vertical direction. The second height change is defined as the difference between the height of the first cushioning element in an uncompressed (assembled) state (i.e., the distance between the top surface and the bottom surface) and the height of the first cushioning element in a compressed state under a defined force. In such embodiments, the second height change is less than the first height change. In some embodiments, the second height change is less than or equal to 95% of the first height change. In some embodiments, the second height change is less than or equal to 80% of the first height change. In some embodiments, the second height variation is less than or equal to 60% of the first height variation. In some embodiments, the second height variation is less than or equal to 30% of the first height variation. In some embodiments, the second height variation is less than or equal to 10% of the first height variation.

[0115] In some embodiments, a first cushioning element (e.g., a medial cushioning element) may be made of a first material, a second cushioning element (e.g., a lateral cushioning element) may be made of a second material, and the first material includes a higher compressibility than the second material. In these embodiments, the first cushioning element may deform more easily under the action of a compressive force. By deforming more easily, the compressibility of the first cushioning element may help the wearer during certain kick-off movements. For example, the higher compressibility of the first cushioning element may be used as an "integrated starting block" for the wearer, which can increase acceleration during a sprint start, increase acceleration during a sharp change in direction (i.e., a cut-in), or both. For example, in the case where the medial cushioning element includes a higher compressibility, when the sole is under a compressive load, the inside of the wearer's foot may be lower (closer to the ground) relative to the outside of the foot, thereby creating a starting block in the transverse direction.

[0116] In some embodiments, the second cushioning element (e.g., the lateral cushioning element) can be made of a first material, the first cushioning element (e.g., the medial cushioning element) can be made of a second material, and the first material includes a higher compressibility than the second material. In these embodiments, the second cushioning element can deform more easily under a compressive load. By deforming more easily, the compressibility of the second cushioning element can help the wearer during certain kick-off movements.

[0117] In some embodiments, the first material and the second material can be different material types. For example, the first material and the second material can be different polymer foam types, such as polyamide foam and ethylene vinyl acetate (EVA) foam. In some embodiments, the first material and the second material can be the same material with different porosity levels. For example, the first material can be an EVA foam with a first porosity, and the second material can be the same EVA foam with a second porosity less than the first porosity. In some embodiments, the first material and the second material can be different 3D printed grid structures with different compressibility.

[0118] In some embodiments, the first cushioning element is made of a first material having a first compressibility, the first compressibility being characterized by a first height change when a force is applied to the first material in a vertical direction, and the second cushioning element is made of a second material having a second compressibility, the second compressibility being characterized by a second height change when the same force is applied to the second material in a vertical direction, and the second height change is less than the first height change. In some embodiments, the second height change is less than or equal to 95% of the first height change. In some embodiments, the second height change is less than or equal to 80% of the first height change. In some embodiments, the second height change is less than or equal to 60% of the first height change. In some embodiments, the second height change is less than or equal to 30% of the first height change. In some embodiments, the second height change is less than or equal to 10% of the first height change.

[0119] In some embodiments, the second cushioning element is made of a first material having a first compressibility, the first compressibility being characterized by a first height change when a force is applied to the first material in a vertical direction, and the first cushioning element is made of a second material having a second compressibility, the second compressibility being characterized by a second height change when the same force is applied to the second material in a vertical direction, and the second height change is less than the first height change. In some embodiments, the second height change is less than or equal to 95% of the first height change. In some embodiments, the second height change is less than or equal to 80% of the first height change. In some embodiments, the second height change is less than or equal to 60% of the first height change. In some embodiments, the second height change is less than or equal to 30% of the first height change. In some embodiments, the second height change is less than or equal to 10% of the first height change.

[0120] In some embodiments, the first and second cushioning elements may include equal first and second undeformed heights (i.e., the distance between the top and bottom surfaces of the elements). In some embodiments, the first cushioning element (e.g., the medial cushioning element) may include a first undeformed height, and the second cushioning element (e.g., the medial cushioning element) may include a second undeformed height that is less than the first undeformed height. In some embodiments, the first cushioning element (e.g., the medial cushioning element) may include a first undeformed height, and the second cushioning element (e.g., the medial cushioning element) may include a second undeformed height that is greater than the first undeformed height.

[0121] In some embodiments, the first cushioning element is made of a first material having a first compressibility, the second cushioning element is made of a second material having a second compressibility, and the first compressibility is at least 20% greater or at least 20% less than the second compressibility. In some embodiments, the first cushioning element is made of a first material having a first compressibility, the second cushioning element is made of a second material having a second compressibility, and the first compressibility is at least 50% greater or at least 50% less than the second compressibility.

[0122] In some embodiments, the first cushioning element and / or the second cushioning element may extend along 10% to 80% of the length of the outsole. In some preferred embodiments, the first cushioning element and / or the second cushioning element may extend along 15% to 70% of the length of the outsole. In some preferred embodiments, the first cushioning element and / or the second cushioning element may extend along 20% ​​to 60% of the length of the outsole. In some preferred embodiments, the first cushioning element and / or the second cushioning element may extend along 25% to 50% of the length of the outsole. In some preferred embodiments, the first cushioning element and / or the second cushioning element may extend along 30% to 40% of the length of the outsole. These lengths have proven to be beneficial because they substantially improve cushioning and / or increase stiffness without adding too much material, i.e., weight, to the outsole. In addition, these lengths allow the first cushioning element and / or the second cushioning element to be used as an "integrated starting block" for the wearer, which can improve the start of a sprint, i.e., allow for a better push-off.

[0123] In some embodiments, the distance between the last point of the outsole and the last point of the first and / or second cushioning elements can be between 30% and 60% of the length of the outsole. In some preferred embodiments, the distance between the last point of the outsole and the last point of the first and / or second cushioning elements can be between 35% and 55% of the length of the outsole. In some preferred embodiments, the distance between the last point of the outsole and the last point of the first and / or second cushioning elements can be between 40% and 50% of the length of the outsole. In particular, the distance can be measured between the last point of the outsole and the point closest to the last point of the first and / or second cushioning elements. By this configuration, a ridge, i.e., an "integrated starting block", can be formed on a portion of the outsole, which allows for better kick-off. Thus, the ridge can be used as an "integrated starting block" for the wearer. Thus, the outsole can allow for an improved sprint start.

[0124] In some embodiments, the first sole section may branch into at least two branches in the direction of the toe portion toward the outsole. In such an embodiment, each of the two branches may overlap at least partially with the second sole section. In some embodiments, the first branch may include at least one first spike and may at least partially accommodate the first cushioning element. In some embodiments, the second branch may include at least one second spike and may at least partially accommodate the second cushioning element. Optionally, the first branch extends along the medial portion of the outsole, and the second branch extends along the lateral portion of the outsole. Through the branches, the outside and the inside of the wearer's foot can be supported separately, which can increase stability. In addition, through the branches, it is possible to avoid that the deformation of one cushioning element significantly affects another cushioning element. It is found that this increases the stability provided by the outsole, particularly during fast running (e.g., sprinting).

[0125] It will be described below that the first branch may include at least one first hole described above and / or the second branch may include at least one second hole described above. In this regard, it should be understood that these holes may have the characteristics of the holes described above. In addition, it will also be understood that these holes may provide the advantages of the holes described above.

[0126] For example, in some embodiments, the first branch may include at least one first hole. In such an embodiment, the at least one first hole may include a lateral side hole pointing toward the lateral portion of the outsole, so that the first cushioning element is exposed toward the second branch. The lateral side hole of the foot may be configured as at least one side hole described above, and provide corresponding advantages. In addition, by pointing to the lateral side hole of the outsole, so that the first cushioning element is exposed toward the second branch, the first cushioning element can be protected from side impacts.

[0127] As another example, in some embodiments, the second branch may include at least one second hole. In such an embodiment, the at least one second hole may include a medial side hole pointing toward the medial portion of the outsole, such that the second cushioning element is exposed toward the first branch. The medial side hole may be configured as at least one side hole described above and provide corresponding advantages. By pointing the medial side hole toward the medial portion of the outsole, such that the second cushioning element is exposed toward the first branch, the second cushioning element may be protected from side impacts.

[0128] In some embodiments, the first branch may include at least one first hole, wherein the at least one first hole includes a first bottom hole, so that the first cushioning element is exposed toward the following surface, on which the outsole will be placed during normal use. The first bottom hole can be configured as the at least one bottom hole described above and provide corresponding advantages.

[0129] In some embodiments, the second branch may include at least one second hole, wherein the at least one second hole includes a second bottom hole, so that the second cushioning element is exposed toward the following surface, on which the outsole will be placed during normal use. The second bottom hole can be configured as at least one bottom hole as described above, and provide corresponding advantages.

[0130] In some embodiments, the first branch may include at least one first hole, wherein the at least one first hole includes a medial side hole, so that the first cushioning element is exposed outwardly from the outsole on the medial side of the foot. The medial side hole may be configured as at least one side hole described above and provide corresponding advantages. Further, the medial side hole may allow the first cushioning element to be visually inspected, so that potential material degradation in the first cushioning element can be more easily identified. In addition, such a hole can be particularly advantageous together with the above-mentioned hole that the first branch may include. For example, if the first branch includes a lateral side hole pointing to the lateral portion of the outsole, so that the first cushioning element is exposed toward the second branch, the medial side hole can be used to obtain improved balance.

[0131] In some embodiments, the second branch may include at least one second hole, wherein the at least one second hole includes a lateral side hole, so that the second cushioning element is exposed outward from the outsole in the lateral direction of the foot. The lateral side hole of the foot can be configured as at least one side hole described above, and provide corresponding advantages. Further, the lateral side hole of the foot can allow the second cushioning element to be visually inspected, so that potential material degradation in the second cushioning element can be more easily identified. In addition, such a hole can be particularly advantageous together with the above-mentioned hole that the second branch may include. For example, if the second branch includes a medial side hole pointing to the medial portion of the outsole, so that the second cushioning element is exposed toward the first branch, the lateral side hole of the foot can be used to obtain improved balance.

[0132] In some embodiments, the first branch may bridge the first cushioning element in the longitudinal direction of the outsole and may be attached to the second sole section at least before and after bridging the first cushioning element. The stability of the outsole may thereby be increased. Furthermore, since loads (e.g., due to bending of the outsole) may be directly transferred between the first sole section and the second sole section, shear forces acting on the first cushioning element may be reduced.

[0133] In some embodiments, the second branch may bridge the second cushioning element in the longitudinal direction of the outsole and may be attached to the second sole section at least before and after bridging the second cushioning element. The stability of the outsole may thereby be increased. Furthermore, since loads (e.g., generated by bending of the outsole) may be directly transferred between the first sole section and the second sole section, shear forces acting on the second cushioning element may be reduced.

[0134] In some embodiments, the first branch may be attached to the second sole section at least partially along the length of the first cushioning element. In particular, in some embodiments, the first branch may be attached to the second sole section at least partially along the length of the first cushioning element on the outside of the foot of the first cushioning element. Thereby, the stability of the outsole may be further increased. In addition, since loads (e.g., caused by bending of the outsole) may be transferred more directly between the first sole section and the second sole section, shear forces acting on the first cushioning element may be reduced.

[0135] In some embodiments, the second branch may be attached to the second sole section at least partially along the length of the second cushioning element. In particular, in some embodiments, the second branch may be attached to the second sole section at least partially along the length of the second cushioning element on the medial side of the foot of the second cushioning element. Thereby, the stability of the outsole may be further increased. Furthermore, since loads (e.g., generated by bending of the outsole) may be transferred more directly between the first sole section and the second sole section, shear forces acting on the second cushioning element may be reduced.

[0136] In some embodiments, the first branch may terminate at a spike attached to the first sole section. Thus, in such an embodiment, the first branch of the first sole section may be attached to the second sole section via the spike. Thus, the fixation of the first sole section to the second sole section may be improved. In some embodiments, the second branch may terminate at a spike attached to the first sole section. Thus, in such an embodiment, the second branch of the first sole section may be attached to the second sole section via the spike. Thus, the fixation of the first sole section to the second sole section may be improved. It is understood that the branches may terminate at the same spike or at different spikes.

[0137] In some embodiments, the cross-section of the first branch and / or the second branch, seen from the heel portion of the outsole, can decrease after bridging the first cushioning element and / or the second cushioning element. Thereby, abrupt changes in stiffness, which could have a negative impact on comfort and / or functionality, can be prevented. Instead, a continuous reduction in stiffness is achieved.

[0138] In some embodiments, at least one reinforcing element may overlap with the first sole section and / or the second sole section. In some embodiments, at least one reinforcing element may also overlap with the first cushioning element and / or the second cushioning element. In some embodiments, at least one reinforcing element may be configured to be located between the wearer's foot and the first cushioning element and / or the second cushioning element. Therefore, support for the wearer's foot can be provided without increasing the thickness of the first sole section and / or the second sole section. In some embodiments, at least one reinforcing element may include a fiber-reinforced composite material, such as a carbon fiber reinforced polymer, a glass fiber reinforced polymer, and / or an aramid fiber reinforced polymer. In some embodiments, at least one reinforcing element may include polyamide or even consist essentially of polyamide. In some embodiments, at least one reinforcing element may include a rod-shaped, finger-shaped, and / or plate-shaped.

[0139] In some embodiments, the first sole section and / or the second sole section do not extend along the entire length of the outsole. This may allow for targeted engineering of the properties of the outsole along the length of the outsole. Exemplarily, the first sole section, which may be more rigid than the second sole section, may extend from the heel portion to the midfoot portion. Thus, the second sole section may extend from the toe portion to the midfoot portion, where the second sole section overlaps the first sole section. Thus, on the one hand, toe flexion may be enhanced, which is advantageous during a sprint start, where more toe flexion is beneficial, and on the other hand, stability is enhanced in the heel portion.

[0140] Furthermore, by the first sole section and / or the second sole section not extending along the entire length of the outsole, the used material can be reduced and thus the weight of the outsole can be reduced.

[0141] The embodiment of the present disclosure also relates to a shoe, which comprises an upper and an outer sole as described above. It can be understood that the advantages of the outer sole as described above also apply to the shoe.

[0142] Some embodiments of the present disclosure relate to a method for manufacturing an outsole, in particular an outsole as described above. It should be understood that the features and corresponding advantages of the outsole described above may also be applied to the method for manufacturing the outsole described. The method comprises the following steps:

[0143] (a) manufacturing a first sole section;

[0144] (b) placing a first placeholder on a medial portion of the first sole section and placing a second placeholder on a lateral portion of the first sole section;

[0145] (c) injection molding the second sole section such that the first sole section and the second sole section are at least partially connected and such that the first place holder and the second place holder are each at least partially located between the first sole section and the second sole section;

[0146] (d) removing the first placeholder and the second placeholder, and

[0147] (e) Arranging a first cushioning element and a second cushioning element between the first sole section and the second sole section, wherein the position of the first cushioning element at least partially corresponds to the position where the first place holder was placed, and wherein the position of the second cushioning element at least partially corresponds to the position where the second place holder was placed.

[0148] The method can allow for increased productivity. For example, increased productivity can be achieved by avoiding the need for a foaming step. As another example, because the first cushioning element and / or the second cushioning element can be pre-formed elements, these elements can be quickly arranged, which can reduce production time.

[0149] In some embodiments, the manufacturing of the first sole section in step (a) may include injection molding, 3D printing and / or compression molding.

[0150] In some embodiments, between step (a) and step (c), the method may include a further step of placing the first sole segment in a mold for injection molding in step (c). In such an embodiment, if the first sole segment is manufactured by injection molding and / or compression molding, the first sole segment may remain in the corresponding mold for subsequent steps. Therefore, the efficiency of the method can be improved.

[0151] In some embodiments, a placeholder used during injection molding of the second sole segment can be used to keep a space (e.g., a cavity) open in which the cushioning element will be arranged. In addition, the placeholder can also ensure that the second sole segment includes a fixed portion and at least one movable portion, and the fixed portion is two-dimensionally connected to the first sole segment, as described below. In some embodiments, the placeholder is a metal element. In some embodiments, the placeholder can be 3D printed. In some embodiments, the placeholder can include a grid and / or a cell structure. In some embodiments, the first placeholder substantially corresponds to the first cushioning element in shape. Similarly, in some embodiments, the second placeholder can substantially correspond to the second cushioning element in shape. Therefore, the cushioning element can be easily arranged in the outsole.

[0152] As described above with respect to the outsole, the first branch of the first sole section can at least partially house the first cushioning element. Additionally, the second branch of the first sole section can at least partially house the second cushioning element. Thus, in some embodiments, the first placeholder can be used to provide a cavity in the first branch, and the second placeholder can be used to provide a cavity in the second branch.

[0153] It will be appreciated that it is preferred to carry out the method steps in the order given above, in particular because efficiency can be increased thereby.

[0154] After step (c), the second sole section may include a fixed portion that is two-dimensionally connected to the first sole section. In addition, at least after step (c), the second sole section may include at least one movable portion that is movable relative to the first sole section such that a distance between the at least one movable portion and the first sole section can be changed, wherein the at least one movable portion at least partially overlaps the first placeholder and / or the second placeholder.

[0155] The at least one movable portion may include a first movable portion overlapping the first placeholder and a second movable portion overlapping the second placeholder. It should be understood that the first movable portion may overlap the first branch of the first sole section and the second movable portion may overlap the second branch of the first sole section.

[0156] In some embodiments, removing the first and second placeholders and / or arranging the first and second cushioning elements between the first and second sole sections may comprise changing the distance between the at least one movable portion and the first sole section. Thus, the placeholders may be removed more easily. Furthermore, the arrangement of the cushioning elements in the outsole may be facilitated. Furthermore, due to the movability of the portions, cushioning elements with different heights may be used. This may allow for easier customization of the outsole.

[0157] In some embodiments, the fixing portion may be arranged at least in the toe portion of the outsole, the midfoot portion of the outsole, or both. Thus, sufficient rigidity, i.e. stability, can be provided for the outsole.

[0158] The first cushioning element and / or the second cushioning element may be adhered to the first sole section. In addition, at least one removable portion of the second sole section may be adhered to the first sole section, the first cushioning element and / or the second cushioning element. Thus, at least one removable portion of the second sole section may be fixed and the cushioning element may be fixed. The adhesion may be implemented by an adhesive, optionally together with a primer. In addition, the adhesion may be implemented additionally or alternatively by welding, such as laser welding, plasma welding, IR welding and / or other methods. In some embodiments, the adhesion may be implemented additionally or alternatively by compression molding.

[0159] Some embodiments of the present disclosure relate to an outsole for a shoe (e.g., a soccer shoe) comprising a shoe last. In such an embodiment, the outsole may comprise a first sole section, a second sole section, a first cushioning element, and a second cushioning element. It should be understood that these elements may be configured as described above. In addition, the corresponding advantages may be correspondingly applicable to an outsole according to another aspect.

[0160] In such an embodiment, the outsole comprises a first sole section, which comprises at least two spikes and is arranged at least in the midfoot portion of the outsole. Furthermore, the outsole comprises a second sole section, wherein the first sole section and the second sole section partially overlap. Furthermore, the outsole comprises a first cushioning element arranged between the first sole section and the second sole section, wherein the first cushioning element overlaps at least one first spike of the first sole section. Furthermore, the outsole comprises a second cushioning element arranged between the first sole section and the second sole section, wherein the second cushioning element overlaps at least one second spike of the first sole section.

[0161] In some embodiments, the second sole section may be a last board, and in particular a forefoot last board. Thus, the first cushioning element and / or the second cushioning element may be arranged between the first sole section and the last board. Thus, the last board may be covered by the first sole section. In some embodiments, the last board may be completely covered by the first sole section. In some embodiments, the last board may include a pin to interact with the inner recess of the spikes of the first sole section. In some embodiments, the last board may further include a slight recess for at least partially accommodating the first cushioning element and / or the second cushioning element. In addition to the last board, a strobel last may be provided at the heel portion of the sole, i.e. the rear foot.

[0162] The described figures each show at least one outsole 1 according to some embodiments. Reference numerals for corresponding features are used consistently. Therefore, all features that have already been described will not be described again.

[0163] Figure 1A first exemplary outsole 1 for a shoe 50, i.e. a soccer shoe, is shown. The outsole 1 comprises a first sole section 2, which comprises a plurality of studs 6a, 6b, 7a, 7b. The first sole section extends from a toe portion 20 of the outsole 1 to a heel portion 30 of the outsole 1. Furthermore, the outsole 1 comprises a second sole section 3, which comprises three studs and extends from the toe portion 20 of the outsole 1 in a direction towards a midfoot portion of the outsole 1. The first sole section 2 and the second sole section 3 partially overlap. Thus, the first sole section 2 and the second sole section 3 do not extend along the entire length of the outsole 1. Furthermore, the outsole 1 comprises a first cushioning element 4 arranged between the first sole section 2 and the second sole section 3. The first cushioning element 4 overlaps with two first studs 6a, 6b of the first sole section 2. Further, the outsole 1 comprises a second cushioning element 5 arranged between the first sole section 2 and the second sole section 3. The second cushioning element 5 overlaps the two second spikes 7a, 7b of the first sole section 2. The first spikes 6a, 6b and the second spikes 7a, 7b are attached to the first sole section 2. The first cushioning element 4 is arranged on the medial part of the outsole 1 and the second cushioning element 5 is arranged on the lateral part of the outsole 1.

[0164] like Figure 1-4 As shown, the first sole section 2 comprises four holes 8a, 8b, 9a, 9b, which at least partially overlap with the first cushioning element 4 or the second cushioning element 5.

[0165] In particular, the four holes 8a, 8b, 9a, 9b include two bottom holes 8b, 9b. Thus, the first bottom hole 8b is adapted to expose the first cushioning element 4 towards the surface on which the outsole 1 will rest during normal use. The first bottom hole 8b extends at least partially between the two first spikes 6a, 6b. The second bottom hole 9b is adapted to expose the second cushioning element 5 towards the surface on which the outsole 1 will rest during normal use. The second bottom hole 9b extends at least partially between the two second spikes 7a, 7b.

[0166] More specifically, the four holes 8a, 8b, 9a, 9b include two side holes 8a, 9a, which are suitable for exposing the first cushioning element 4 in the medial direction of the outsole 1 and the second cushioning element 5 in the lateral direction of the outsole 1. The two side holes 8a, 9a do not have a closed profile in the first sole section. Instead, they are each a cut-out in the first sole section, which is defined by the second sole section so that the corresponding hole 8a, 9a is formed.

[0167] Figure 5A detail of a first exemplary outsole according to some embodiments is shown in a bottom view, wherein the modification is that the first sole section 2 comprises two further holes 8c, 9c which at least partially overlap the first cushioning element 4 or the second cushioning element 5. Figure 5 The modifications shown are specifically made by Figures 16 to 19 Shown.

[0168] Generally with respect to the description of the figures, the holes at least partially overlapping the first cushioning element 4 are referred to as first holes 8a, 8b, 8c. The holes at least partially overlapping the second cushioning element 5 are referred to as second holes 9a, 9b, 9c.

[0169] from Figure 2 It can be seen in particular that, as seen from the heel portion 30 of the outsole 1, the first cushioning element 4 and the second cushioning element 5 do not extend beyond the region of the outsole 1 that is configured to support the metatarsal fat pad, as also indicated by arrow 100. Thus, as seen 100 from the heel portion 30, the first sole section 2 extends beyond the region of the outsole 1 that is configured to support the metatarsal fat pad in the direction toward the toe portion 20, which region has a reduced cross-section relative to the cross-section in the region where the first sole section 2 overlaps with the first cushioning element 4 and the second cushioning element 5.

[0170] from Figure 3 It can be seen in particular that the first cushioning element 4 and the second cushioning element 5 are at least partially arranged in the midfoot portion 25. As a result, the first sole section 2 and the second sole section 3 overlap in the midfoot portion 25. In addition, the first sole section 2 and the second sole section 3 also overlap in the toe portion 20.

[0171] The first cushioning element 4 and the second cushioning element 5 include a foam material, which may have strain rate dependent material properties. Both cushioning elements 4, 5 extend along about 25% of the length of the outsole 1. Moreover, the distance between the rearmost point of the outsole 1 and each of the first cushioning element 4 and the second cushioning element 5 is about 50% to 55% of the length of the outsole 1.

[0172] according to Figures 1 to 19 All exemplary outsoles of the illustrated embodiments comprise a first sole section 2 which extends from a heel portion 30 and branches into at least two branches 10, 15 in the direction towards a toe portion 20 of the outsole 1. Thus, each of the two branches 10, 15 overlaps at least partially with a second sole section 3.

[0173] For example, in Figures 1 to 4In the embodiment of the present invention, the first branch 10 includes two first spikes 6a, 6b and at least partially accommodates the first cushioning element 4. In addition, the second branch 15 includes two second spikes 7a, 7b and at least partially accommodates the second cushioning element 5. The first branch 10 extends along the medial part of the outsole 1, and the second branch 15 extends along the lateral part of the outsole 1. In addition, the first branch 10 includes two first holes 8a, 8b, and the second branch 15 includes two second holes 9a, 9b. Figures 16 to 19 A possible arrangement of the holes on the branches of the first sole section 2 is described in more detail.

[0174] As from Figures 1 to 4 As can be further seen in the embodiment of the present invention, the first branch 10 bridges the first cushioning element 4 in the longitudinal direction of the outsole 1 and is attached to the second sole section 3 at least after bridging the first cushioning element 4. Furthermore, the second branch 15 bridges the second cushioning element 5 in the longitudinal direction of the outsole 1 and is attached to the second sole section 3 at least after bridging the second cushioning element 5. Thus, the first branch 10 ends at the spike 40 attached to the first sole section 2 and the second branch 15 ends at the spike 45 attached to the first sole section 2. The cross section of the first branch 10, seen from the heel portion 30 of the outsole 1, decreases after bridging the first cushioning element 4. Furthermore, the cross section of the second branch 15, seen from the heel portion 30 of the outsole 1, decreases after bridging the second cushioning element 5.

[0175] Figure 6 and Figure 7 An exemplary shoe 50 according to some embodiments is shown, which includes a second exemplary outsole 1. The shoe 50 also includes an upper 55. The second exemplary outsole 1 is basically configured as, for example Figure 1 The first exemplary outsole is shown in FIG. This is particularly worth understanding in the case of identical use of reference numerals. Therefore, all features that have already been described above will not be described again. However, Figure 6 and Figure 7 The outsole depicted in does not include bottom holes 8b, 9b like the first exemplary outsole. In addition, the first sole section 2 has a frame-like structure. Further, the first branch 10 includes the lateral side hole 8c pointing to the lateral part of the outsole 1, so that the first cushioning element 4 is exposed toward the second branch 15. In addition, the first branch 10 includes the medial side hole 8a, so that the first cushioning element 4 is exposed from the outsole 1 on the medial side of the foot. Therefore, the second branch 15 includes the medial side hole 9c (hidden) pointing to the medial part of the outsole 1, so that the second cushioning element 5 is exposed toward the first branch 10. In addition, the second branch 15 includes the lateral side hole 9a, so that the second cushioning element 5 is exposed from the outsole 1 to the lateral direction of the foot.

[0176] Figure 8 and Fig. 9 Shown according to Figure 6 and Figure 7 A second exemplary outsole of the present invention, wherein the branches 10, 15 do not include side holes 8c, 9c facing each other.

[0177] from Figures 6 to 9 It can be further seen in the embodiment of the outsole 1 that the first branch 10 bridges the first cushioning element 4 in the longitudinal direction of the outsole 1 and is attached to the second sole section 3 at least before and after bridging the first cushioning element 4. In addition, the second branch 15 bridges the second cushioning element 5 in the longitudinal direction of the outsole 1 and is attached to the second sole section 3 at least before and after bridging the second cushioning element 5. As a result, both the first branch 10 and the second branch 15 end after bridging the corresponding cushioning elements and do not extend into the toe area 20. In addition, compared with the embodiments shown in the previous figures, Figures 6 to 9 The second sole section 3 shown in FIG. 4 comprises two additional studs in the forefoot region. In the previously described embodiment, the two studs in the forefoot region were arranged on the first sole section 2 and were provided with reference numerals 40 , 45 .

[0178] Fig.10 and Fig.11 Another exemplary shoe 50 is shown, which includes a third exemplary outsole 1 according to some embodiments. The third exemplary outsole 1 is substantially configured as the exemplary outsole described above. This is particularly worth understanding in the case of equivalent reference numerals. Therefore, all features that have already been described above will not be described again. However, as Fig.10 As shown, the outsole 1 differs from the previous outsole in that the first sole section 2 and the second sole section 3 overlap only in a small part. Firstly, the first cushioning element 4 and the second cushioning element 5 are arranged directly between the upper 55 and the first sole section 2. In addition, the first cushioning element 4 overlaps only one first stud 6a, and the second cushioning element 5 overlaps only one second stud 7a.

[0179] Fig.12 and Fig.13 A fourth exemplary outsole 1 according to some embodiments is shown. The fourth exemplary outsole 1 is configured substantially as the exemplary outsole described above. This is particularly worth understanding in the case of equivalent use of reference numerals. Therefore, all features that have already been described above are no longer described. In addition, the fourth exemplary outsole 1 includes a reinforcing element 60 that overlaps the first sole section 2 and the second sole section 3. Thereby, one of the reinforcing elements 60 overlaps the first cushioning element 4, wherein another of the reinforcing elements 60 overlaps the second cushioning element 5. The depicted reinforcing element 60 may include a hollow material rod, i.e. a tube, and / or a full material rod.

[0180] Fig.14 and Fig.15 A fifth exemplary outsole 1 is shown, which corresponds substantially to Figure 8 and Fig. 9 However, the fifth exemplary outsole 1 differs from the aforementioned exemplary outsole in that the first cushioning element 4 and the second cushioning element 5 (hidden) comprise 3D printed parts, namely a 3D printed mesh structure.

[0181] Figures 16 to 19 A sixth exemplary outsole 1 according to some embodiments is shown. The sixth exemplary outsole 1 is substantially configured as described above according to Figures 1 to 5 This is particularly worth understanding in the case of equivalent reference numerals. Therefore, all features that have already been described above will not be described again. However, the arrangement of the holes will be referred to below. Figures 16 to 19 Describe in detail.

[0182] The first branch 10 of the first sole section 2 comprises three first holes 8a, 8b, 8c. Thus, the three first holes 8a, 8b, 8c comprise a lateral hole 8c pointing to the lateral part of the outsole 1, such that the first cushioning element 4 is exposed towards the second branch 15. Furthermore, the three first holes 8a, 8b, 8c comprise a first bottom hole 8b, such that the first cushioning element 4 is exposed towards the surface on which the outsole 1 will rest during normal use. Furthermore, the three first holes 8a, 8b, 8c comprise a medial hole 8a, such that the first cushioning element 4 is exposed outwardly from the outsole 1 on the medial side of the foot.

[0183] Furthermore, the second branch 15 comprises three second holes 9a, 9b, 9c. Thus, the three second holes 9a, 9b, 9c comprise the medial-side hole 9c pointing to the medial-side branch of the outsole 1, so that the second cushioning element 5 is exposed toward the first branch 10. Furthermore, the three second holes 9a, 9b, 9c comprise the second bottom hole 9b, so that the second cushioning element 5 is exposed toward the following surface, on which the outsole 1 will be placed during normal use. Furthermore, the three second holes 9a, 9b, 9c comprise the medial-side hole 9a, so that the second cushioning element 5 is exposed outwardly from the outsole 1 in the lateral direction of the foot.

[0184] Furthermore, if Fig.18 , the second sole section 3 comprises cutouts 70. These cutouts 70 can be used to locally reduce the hardness of the outsole 1. In the fifth exemplary outsole, the cutouts 70 are arranged between the first branch 10 and the second branch 15. However, as Fig. 9 As depicted in , this is not necessary.

[0185] Figure 20 to Figure 24A seventh exemplary outsole 1 according to some embodiments is shown. The seventh exemplary outsole 1 is configured substantially as the exemplary outsole described above. This is particularly worth understanding in the case of equivalent use of reference numerals. Therefore, all features already described above are no longer described. However, the second sole section 3 includes a fixed portion 80c that is two-dimensionally connected to the first sole section 2. In addition, the second sole section 3 includes at least one movable portion 80a, 80b, which can be moved relative to the first sole section 2, so that the distance between the at least one movable portion 80a, 80b and the first sole section 2 can be changed.

[0186] like Fig. 20 , 21 As shown in Figures 23 and 24, at least one movable portion 80a, 80b includes a first movable portion 80a overlapping with the first cushioning element, and a second movable portion 80b overlapping with the second cushioning element. The fixed portion 80c is arranged on the toe portion 20 of the outsole 1 and the midfoot portion 25 of the outsole 1. Each of the movable portions 80a, 80b and the fixed portion 80c is substantially tongue-shaped. In addition, the portions 80a, 80b, 80c point to the heel portion 30 of the outsole 1. In addition, each of the movable portions 80a, 80b overlaps with the branches 10, 15 of the first sole section 2. The movable portions 80a, 80b are formed integrally with the fixed portion 80c. In order to complete the manufacture of the outsole 1, the movable portions 80a, 80b can be adhered to the first sole section 2, the first cushioning element 4 and / or the second cushioning element 5.

[0187] Fig.25 A schematic diagram of an exemplary method 1000 for manufacturing an outsole 1 is shown. The method 1000 is particularly useful for manufacturing an outsole as described above. Thus, Figures 20 to 24 The outsole 1 of FIG. 1 specifically illustrates various aspects of a method 1000 according to some embodiments. The method 1000 comprises the following steps:

[0188] a) manufacturing 1010 a first sole section 2;

[0189] b) placing 1020 a first place holder on the medial part of the first sole section 2 and placing a second place holder on the lateral part of the first sole section 2;

[0190] c) injection molding 1030 the second sole section 3 such that the first sole section 2 and the second sole section 3 are at least partially connected and such that the first place holder and the second place holder are each at least partially located between the first sole section 2 and the second sole section 3;

[0191] d) removing 1040 the first place holder and the second place holder, and

[0192] e) Arranging 1050 a first cushioning element 4 and a second cushioning element 5 between the first sole section 2 and the second sole section 3, wherein the position of the first cushioning element 4 at least partially corresponds to the position where the first place holder was placed, and wherein the position of the second cushioning element 5 at least partially corresponds to the position where the second place holder was placed.

[0193] exist Fig.24 d) of removing 1040 the first and second place holders has been performed, however, since no first and second cushioning elements 4, 5 are arranged between the first and second sole sections 2, 3, step e) has not been performed.

[0194] like Fig. 20 and 21 As shown, said step e) has been carried out, however, the at least one movable part 80a, 80b of the second sole section 3 is not yet adhered to the first sole section 2, the first cushioning element 4 and / or the second cushioning element 5.

[0195] Fig.26 An outsole 500 according to some embodiments is shown. The outsole 500 is for a shoe, i.e. a soccer shoe. The outsole 500 comprises a first sole section 2, the first sole section 2 comprising a plurality of studs 6a, 6b, 7a, 7b. The first sole section 2 extends from a toe portion 20 of the outsole 500 to a heel portion 30 of the outsole 500. Furthermore, the outsole 500 comprises a second sole section (which is hidden). The first sole section 2 and the (hidden) second sole section partially overlap.

The outsole 101 may include a first cavity 104a and / or a first cavity 105a for accommodating the first cushioning element 104 and / or the second cushioning element 105. The first cavity 104a may have an opening 104b for entering the first cavity 104a. The second opening 105a may also have an opening 105b for entering the second cavity 105a. The opening 104b and / or the opening 105b may be disposed on the upper side of the outsole 101, for example, on a side facing the insole of the shoe. As can be seen, openings 104b and / or openings 105b are substantially smaller than the largest surface of respective cavities 104a, 104b, which helps accommodate first cushioning element 104 and second cushioning element 105, respectively. This is also advantageous from a manufacturing perspective, as further detailed below.

[0200] As described above, outsole 101 may include various features of outsole described elsewhere in this disclosure. For example, first cavity 104a and / or second cavity 105a may have holes 8a, 8b, 8c, 9a, 9b, 9c, as described in more detail elsewhere herein.

[0201] The method (XXXVI) for manufacturing the outsole 101 may include one or more method steps described herein in the context of other embodiments. Alternatively or additionally, the method (XXXVI) for manufacturing the outsole 101 may in particular include the following steps:

[0202] a) manufacturing an integrally formed outer sole 101, wherein the outer sole 101 comprises a first cavity 104a and / or a second cavity 105a, each cavity having an opening 104b, 105b for entering the cavity 104a, 105a;

[0203] b) placing the outsole 101 in a mould, preferably a casting mould, optionally wherein the mould comprises any of the features as described elsewhere herein with respect to the mould, optionally wherein the mould is opened before placing the outsole 101 in said mould;

[0204] c) applying a cushioning material (e.g., a foam material) into the first cavity 104a and / or the second cavity 105a, wherein the cushioning material may be any suitable cushioning material, preferably polyurethane, wherein applying the cushioning material preferably comprises pouring and / or injection, most preferably pouring;

[0205] d) at least partially closing the mold so that the cushioning material and the outsole 101 are at least partially connected (adhered, bonded, etc.) within the first cavity 104a and / or the second cavity 105a to form the first cushioning element 104 and / or the second cushioning element 105;

[0206] The advantage of this method (XXXVI) is that the outsole 101 can be formed in one piece and can be easily connected to the upper 55, as described elsewhere herein. In particular, this method (XXXVI) may not need to manufacture separate sole sections and / or removable parts. In addition, the cushioning elements 104, 105 can be directly connected (adhesion, bonding, etc.) to the outsole 101. Therefore, the method (XXXVI) is quite simple, direct, and requires a small number of individual steps. In particular, since fewer manual steps are required, the quality of the outsole 101 can be improved. As is well known, manual steps may be prone to error. Thus, complexity is reduced, and the method (XXXVI) is more cost-effective. In addition, since adhesives may not be required, sustainability is improved. This can further reduce the weight of the outsole 101. Another advantage of the method (XXXVI) is that it allows the various geometries of the outsole 101 and / or the parts of the outsole 101 to be provided. This may be because the cavities 104a, 105a can be filled with cushioning materials in a liquid state.
