Description

1. Technical field

[0001] The present invention relates to articles of footwear, specifically to socks ade-signed for athletes, such as football players. More particularly, the invention pertains to articles of footwear, such as socks with enhanced grip features around the ankle area to improve ball control.2. Prior art

[0002] Articles of footwears are becoming more and more important. Athletes, in particular soccer players rely heavily on their footwear and in particular socks for optimal performance.

[0003] Traditional articles of footwear, such as soccer socks are primarily designed to provide comfort and support within the shoe, with grip features focused on the interior surfaces that contact the foot. However, recent research in athlete science has revealed that football players often make significant contact with the ball using the medial ankle area, a part of the sock that is exposed outside the shoe.

[0004] There is a growing need to provide for more functionality in relation to these articles of footwear.

[0005] Exemplarily, the following prior art documents may be mentioned in the context of the present disclosure.

[0006] Document US 2015 / 0 264 995 A1 relates to socks and other articles of sportswear for increasing grip on a contacted ball, as well as methods for manufacturing the same. A sock includes one or more coating material portions disposed on at least a portion of a sock base material of the sock leg. The one or more coating material portions include a coating base material or a coating base material and an aggregate material, such that a coefficient of friction between the coating material portions and the contacted ball is higher than a coefficient of friction between the sock base material and the contacted ball. Document US 2005 / 0 144 703 A1 relates to a slip-resistant stocking of the type that is worn by ambulatory hospital patients for walking directly on smooth, hard hospital floors, which comprises a stocking, such as a tube sock, having a slip-resistant material applied to the foot portion of the stocking around the periphery of an outside surface thereof, such that slip-resistant material is always positioned under the bottom of the foot of the patient regardless of the rotational orientation of the foot portion of the stocking around the axis of the foot. The slip-resistant material can be on the inside as well as the outside of the stocking, so the stocking also will be slip-resistant when worn inside out. The slip-resistant material can be provided as discreet elements deposited at spaced locations around the stocking. The elements can be formed of recognizable shapes or decorative designs, which will be visible on the top of the stocking.

[0007] Document JP 6 613 013 B1 describes to a sock body, a plurality of anisotropic first anti-slip portions and, and a plurality of anisotropic second anti-slip portions. The first anti-slip portion is disposed in a region covering the proximal phalanx and metatarsal bone of the instep and sole, and in the region covering the first to third proximal phalanges and the first to third metatarsals.

[0008] Document US 8 220 077 B1 relates to a safety stocking comprising a stretchable fabric material forming a foot section and a leg section, said foot section having a length extending from and including a toe portion to a heal portion with an exterior top surface extending from an exterior bottom surface and a non-skid tread coupled to both said bottom surface and said top surface of said foot section along said length of said foot section.

[0009] Document US 11 812 794 B2 relates to a sock having integrally knit grip strips where a first area of the grip strip has a first number of grip yarn knit courses and a second area of the grip strip has a second number of grip yarn knit courses different from the first number of grip yarn knit courses.

[0010] Despite the advances that some of the prior art references may have provided, in particular in the field of sports footwear, there remains a need for further improvement. Current designs are limited in scope and application. For instance, there remains a gap in the market for articles of footwear in particular socks that provide enhanced functionalities. The prior art in particular does not address the need for assisting shooting and / or passing by way of such an article of footwear. Further the prior art does not address the need for improved grip of such an article of footwear. Further, the prior art does not address provision of this function effectively under varying conditions, such as wet weather.

[0011] Against this background, it is an object of the present invention to provide an improved article of footwear that addresses one or more or all of the above-mentioned disadvantages.3. Summary of the invention

[0012] The above-mentioned objects are at least partially achieved by the subject-matter of the independent claims. Preferred embodiments are subject of the dependent claims, and other suitable aspects of the present invention are described through the overall disclosure of the present application.

[0013] The objects are inter alia solved by an article of footwear, such as a sock or a calf sleeve, in particular a sock or a calf sleeve used for playing soccer, the article of footwear configured to be worn by a foot of a user and then to be received in a shoe, the article of footwear comprising: an inside shoe portion and an outside shoe portion; wherein the outside shoe portion comprises a control element; wherein the control element is configured to assist with shooting and / or passing and / or receiving a ball a ball and further configured to reinforce an ankle portion of the article of footwear.

[0014] In this manner, the article of footwear provides a control element that allows for improved functionality, namely, to assist with shooting and / or passing a ball. As describes elsewhere herein, this may comprise that grip is improved for shooting a ball. The article of footwear has the advantage that it can be worn by a foot within a shoe, whilst at the same time providing for such improved grip. In turn, it facilitates increasing an area than can make contact with a ball, e.g., during playing soccer. The advantages of the shoe are not deteriorated thereby. Hence, the article of footwear can function in synergy with the shoe.

[0015] The outside shoe portion includes a control element that is strategically positioned to assist with shooting and / or passing a ball. This control element may provide enhanced grip and precision, thereby improving the user's ball-handling skills. Additionally, the control element is further configured to reinforce the ankle portion of the article of footwear. This dual functionality addresses the challenge of providing both improved ball control and ankle support, which may be critical for soccer players who require both agility and stability. The communication between the control element and the ankle portion may be facilitated by the material properties and / or structural design. This may ensure that the reinforcement is both effective and unobtrusive.

[0016] The reinforcement of the ankle portion may help in reducing the risk of injuries by providing additional support and stability to the ankle joint, which may often be subjected to high stress during soccer activities.

[0017] The placement of the control element on the outside shoe portion is particularly advantageous as it aligns with the areas of the foot that interact most frequently with the ball, thereby optimizing the effectiveness of the control element. The control element may be integrated into the outside shoe portion in such a manner that it maintains a seamless connection with the rest of the sock, ensuring that the functionality of the control element may not interfere with the overall comfort and fit of the article of footwear. The outside shoe portion is not necessarily limited to be completely outside in a shoe when worn as understood by the skilled person. In some examples, the outside shoe portion may extend at least partially inside the shoe when worn.

[0018] The inside shoe portion, in contrast, may be designed to offer comfort and a snug fit, ensuring that the article of footwear remains securely in place during vigorous activities. This arrangement not only enhances the overall performance of the user but also addresses the need for durability and comfort in soccer socks, making it a comprehensive solution for soccer players. The inside shoe portion is not necessarily limited to be completely within in a shoe when worn as understood by the skilled person. In some examples, the inside shoe portion may extend at least partially outside the shoe when worn.

[0019] The inside shoe portion and the outside shoe portion may be integral parts of the article of footwear, ensuring that the sock fits snugly within the shoe and provides the necessary support and comfort to the foot of the user. Notably, the article of footwear may comprise further portions and is not limited to the inside shoe portion, the outside shoe portion and the ankle portion.

[0020] The article of footwear, such as a sock or a calf sleeve, described herein may be particularly useful in conjunction with a sports shoe, such as a soccer shoe. However, it should be noted that the article of footwear, such as a sock or a calf sleeve could be used substantially with any kind of shoes including, but not limited to football shoes, hiking boots, sneakers, basketball shoes, rugby shoes, baseball shoes, golf shoes, tennis shoes, cross-training shoes. Moreover, the article of footwear, such as a sock or a calf sleeve may be used in conjunction with shoes for any kind of athletic activity. The term athletic activity is to be understood such that it encompasses one or more and / or any combination of at least the following non-exhaustive list: aerobics, athletic exercises, running, hiking, climbing, group fitness classes, walking, cycling, yoga, soccer, tennis, football, basketball, doing a workout, volleyball, gymnastics, weight-lifting, cross-training, baseball, softball, rugby, field hockey, wrestling, squash, track and field (such as sprinting, long jump, high jump), cross-country skiing.

[0021] An article of footwear, as used herein, may encompass various forms, including but not limited to, socks, calf sleeves, and similar items having the function to provide coverage, support, or protection to the foot or lower leg. The article of footwear may include socks that provide full or partial foot coverage or calf sleeves that lack complete foot coverage. In certain embodiments, a calf sleeve may be designed to cover the calf region without extending over the foot and may further comprise an elasticated band or similar fastening mechanism at the lower edge to ensure secure placement during use. Thus, the term "article of footwear" is intended to broadly encompass all such variations.

[0022] The article of footwear may also facilitate receiving of a ball or similar object. This configuration assists in enhancing control and accuracy during the act of receiving the ball, thereby providing improved handling and maneuverability.

[0023] The above-mentioned advantages are also applicable to the following preferred embodiments.

[0024] According to a preferred embodiment of the present disclosure, the outside shoe portion is at least partially exposed to an exterior when the article of footwear is worn by a foot of a user and then received in a shoe.

[0025] The specific mechanism of communication between the components in this embodiment involves the outside shoe portion being at least partially exposed to an exterior when the article of footwear is worn by a foot of a user and then received in a shoe. This exposure to the exterior allows the control element, which is part of the outside shoe portion, to interact directly with external elements such as a soccer ball. This enhances functionality of the control element, as its partial exposure ensures that it can effectively assist with ball control during play. This direct interaction with the ball may be crucial for improving the precision and power of shooting and passing, as the control element can directly influence the ball's trajectory and / or speed.

[0026] Additionally, the exposure of the outside shoe portion to the exterior while the article of footwear is within a shoe ensures that the reinforcement provided to the ankle portion is not compromised by the shoe's structure. This dual functionality-enhanced ball control and ankle support-provides a significant advantage to the user, particularly in the context of soccer where both precise ball handling and ankle stability are critical.

[0027] According to a preferred embodiment of the present disclosure, the control element is arranged on an outer surface of the outside shoe portion.

[0028] By situating the control element on the outer surface, the design ensures that the control element is in direct contact with the external environment, thereby optimizing its functional interaction with a soccer ball during play. This arrangement enhances the tactile feedback and control when shooting or passing the ball, as the control element is strategically positioned to maximize its effectiveness in these actions. Additionally, placing the control element on the outer surface allows for a more seamless integration with the overall design of the footwear, ensuring that it may not interfere with the comfort or fit of the sock when worn inside a shoe.

[0029] According to a preferred embodiment of the present disclosure, the control element is configured to increase a grip between the article of footwear and a ball.

[0030] This enhanced grip may be achieved through increased surface contact between the control element and the ball, which may involve microstructures or adhesive properties that improve the tactile interaction. Further, the control element may be composed of one or more materials which provide for a high friction coefficient between the control element and the ball. Additionally or alternatively, the control element may include textured and / or patterned surfaces designed to enhance grip between the control element and the ball. This embodiment has the advantage that it enhances the user's ability to control the ball during play, providing better precision and accuracy in shooting and passing. Further, the increased grip can contribute to improved performance by reducing slippage between the foot and the ball, thereby allowing for more effective transfer of force from the foot to the ball. This can result in more powerful and controlled kicks. Moreover, the reinforcement of the ankle portion, as mentioned elsewhere herein, is complemented by the increased grip, as it ensures that the foot remains stable within the shoe, improving balance and enhancing overall comfort. Additionally, the increased grip feature may also enhance the durability of the article of footwear by reducing wear and tear caused by frequent ball contact, thereby extending the lifespan of the product.

[0031] The control element being configured to increase a grip between the article of footwear and a ball does not necessarily limit the control element to be present at the location where grip enhancement is provided as long as means are provided that allow for said grip enhancement. It is appreciated that the increase of grip may pertain to all kind of weather conditions, e.g. it may be suitable for wet and dry conditions at the same time.

[0032] According to a preferred embodiment of the present disclosure, the control element comprises a single material, wherein the control element preferably consists of a single material, and wherein the control element is preferably configured to provide a first grip force between the article of footwear and a ball under essentially wet conditions and a second grip force between the article of footwear and a ball under essentially dry conditions, wherein the first grip force and the second grip force deviate by at most 50%, preferably at most 40%, preferably at most 30%, preferably at most 20%, preferably at most 10% of the second grip force.

[0033] The described feature of the article of footwear offers several advantages: By comprising or consisting of a single material, the control element may simplify the manufacturing process. This may lead to cost savings in production and reduce the likelihood of manufacturing defects that can arise from using multiple materials. The use of a single material for the control element may ensure consistent performance characteristics. This can be particularly important for athletes who rely on predictable behavior from their footwear. A single material control element may also contribute to the overall durability of the footwear. It is believed that multiple materials may in some specific occasion lead to weak points where different materials meet. A single material construction can be more robust.

[0034] The control element may also provide an essentially consistent grip forces under both wet and dry conditions. This means that the footwear will perform reliably regardless of weather conditions, which is crucial for outdoor sports. In particular, shooting and / or passing and / or dribbling and / or deceiving a ball may be more predictable. Further, the specification that the first grip force (wet conditions) and the second grip force (dry conditions) deviate by at most 50%, and preferably less, ensures that the athlete experiences minimal changes in grip. This consistency can improve performance and reduce the risk of slips or falls. This is even more pronounced when the difference is only 40% and / or only 10%.

[0035] The ability of the control element to perform well in both wet and dry conditions may make the footwear versatile, suitable for various environments and weather conditions. This can be a significant selling point for consumers looking for all-weather footwear.

[0036] According to a preferred embodiment of the present disclosure, the control element is arranged in a pattern.

[0037] This patterned arrangement can be configured to optimize the interaction between the foot of the user and the ball, thereby improving the user's ability to shoot and / or pass the ball with greater precision and control. Additionally, the patterned control element can provide targeted reinforcement to the ankle portion of the article of footwear, offering improved support and stability to the user. This can be particularly beneficial in high-impact sports such as soccer. Furthermore, the patterned arrangement of the control element can facilitate better distribution of pressure and impact forces across the foot, which is particularly beneficial for complex foot movements. The deliberate patterning of the control element may ensure that it is not randomly and / or haphazardly placed, but rather strategically positioned to maximize its effectiveness in assisting with ball control and reinforcing the ankle.

[0038] According to a preferred embodiment of the present disclosure, the pattern comprises a connected pattern and / or a continuous pattern, and / or a discontinuous pattern.

[0039] The connected pattern facilitates a seamless interaction between various segments of the control element, ensuring uniform distribution of forces and enhancing the overall structural integrity of the control element. This pattern may aid in providing consistent functionalities, including but not limited to reinforcement to the ankle portion, thereby improving stability and balance.

[0040] The continuous pattern may ensure that the control element extends uninterrupted, e.g., over a significant portion of the outside shoe portion. This may maximize the area of contact with the ball during shooting and / or passing. This maximized contact area enhances the user's control over the ball, leading to more precise and powerful shots and passes.

[0041] The discontinuous pattern may allow some of the stretch of the article of footwear to still be present. This may depend on the covered surface area and / or the tensile strength of the applied material as understood by the skilled person. E.g., such patterns may be beneficial to dial in stretch properties in case more or less is needed.

[0042] Further, the discontinues pattern may introduce strategically placed gaps within the control element, which can provide flexibility and breathability to the article of footwear. These gaps may allow for localized stretching and movement, accommodating the natural motion of the foot and ankle during dynamic activities such as soccer. Additionally, the discontinuous pattern can aid in moisture management by allowing air to circulate more freely, thereby keeping the foot cooler and drier during play.

[0043] It is noted that the continuous pattern may comprise a plain pattern. The discontinuous pattern may comprise an interrupted pattern.

[0044] According to a preferred embodiment of the present disclosure, the connected pattern comprises a grid pattern, a hexagonal pattern, such as a honeycomb pattern, a triangular pattern, a circular pattern, a network pattern, a spiral pattern, a radial pattern, a lattice pattern.

[0045] The connected pattern comprising a grid pattern introduces a structured and uniform arrangement of elements that can provide consistent reinforcement and control across the ankle portion, potentially improving stability and precision during ball handling.

[0046] The hexagonal pattern offers a more flexible and resilient structure, distributing forces evenly and allowing for better adaptability to the foot's movements, which can enhance comfort and performance.

[0047] The honeycomb pattern, known for its strength and lightweight properties, can provide robust support while minimizing additional weight, thus maintaining agility and speed.

[0048] The triangular pattern, with its geometric stability, can offer superior resistance to deformation, ensuring that the control element maintains its shape and effectiveness over time.

[0049] It is believed that the circular pattern may have the advantage to provide a more dynamic and responsive reinforcement.

[0050] The network pattern, characterized by interconnected nodes and links, can offer a combination of flexibility and strength, ensuring that the control element can adapt to various stresses while providing consistent support.

[0051] The spiral pattern introduces a unique mechanism of distributing forces in a radial manner, which can enhance the overall balance and control of the foot during complex maneuvers.

[0052] The radial pattern, which may emanate from a central point, can provide a focused reinforcement that supports the ankle from multiple directions, improving stability and may reducing the risk of injury.

[0053] The lattice pattern, which may comprise crisscrossing elements, can offer a comprehensive reinforcement structure that combines flexibility with strength, ensuring that the control element can support the ankle effectively while allowing for natural foot movements.

[0054] Each of these patterns brings a distinct mechanism of communication between the components of the control element and the ankle portion of the article of footwear, enhancing the overall functionality and performance of the sock in assisting with shooting and passing a ball while reinforcing the ankle.

[0055] According to a preferred embodiment of the present disclosure, the continuous pattern comprises a single closed surface.

[0056] This may have the advantage to restrict the stretch of the article of footwear in all directions. Thereby, it may provide for a constraining feeling. This may lead to a perceivable support, appreciated by the wearer.

[0057] The continuous pattern, being a single closed surface, may ensure that the control element is uniformly distributed across the outside shoe portion. This uniform distribution may aid in providing consistent support and reinforcement to the ankle portion. This may be critical for maintaining stability and balance during dynamic movements such as shooting and passing a ball.

[0058] Additionally, the single closed surface of the continuous pattern facilitates the manufacturing process by simplifying the design and reducing the number of seams or joints that need to be created. Thereby, production costs may be lowered and / or the structural integrity of the article of footwear may be improved.

[0059] Furthermore, the continuous pattern can enhance the tactile feedback experienced by the user, as the uniform surface can provide a more predictable and controlled interaction with the ball. This can lead to improved performance in terms of ball control and accuracy during play.

[0060] Notably, the friction between ball and a closed surface may be expected to be high in this embodiment. On the other hand, the area covered by the control element might not adapt as much anymore to the contours of the ankle bone / foot geometry. In one example, it might wrinkle. Nonetheless, in some cases even such wrinkles may be desired for the user.

[0061] According to a preferred embodiment of the present disclosure, the discontinuous pattern comprises one or more elements, preferably a plurality of elements, wherein each element has a distinct boundary, wherein the discontinuous pattern preferably comprises one or more, preferably a plurality of dots, and / or elongate elements, such as lines.

[0062] The distinct boundary of each element within the discontinuous pattern ensures that the control element can effectively interact with the ball, providing precise feedback and control during play.

[0063] This discontinuous pattern is preferably composed of one or more dots, or alternatively, a plurality of dots, which may be strategically placed to optimize control and reinforcement.

[0064] The discontinuous pattern may include one or more elongate elements, or a plurality of elongate elements, which are preferably lines. These elongate elements contribute to the structural integrity and flexibility of the control element, thereby enhancing the user's ability to manipulate the ball while providing additional support to the ankle portion.

[0065] The incorporation of dots or elongate elements in a discontinuous pattern allows for targeted reinforcement and flexibility, ensuring that the article of footwear can adapt to the dynamic movements required in soccer.

[0066] The elongate elements, being lines, offer a streamlined design that can distribute pressure evenly across the ankle portion, thereby improving overall comfort.

[0067] According to a preferred embodiment of the present disclosure, a first element of the plurality of elements comprises a first material and a second element of the plurality of elements comprising a second material, wherein the second material is different than the first material.

[0068] The use of different materials has the advantage to provide targeted functionality. For instance, a first material may be provided to cater for wet conditions and a second material may be provided to cater for dry conditions.

[0069] Using two materials may also achieve a full coverage around the outer periphery of the control element. This may be the case as long as a material of the article of footwear has high stretch properties and then elements such as dots or the like of a less stretchy but more grippy functionalities may be provided on top thereon. This may be understood to be similar to a base coating layer followed by a subsequent layer of material.

[0070] Further, the first material, which constitutes the first element, may be selected for its properties such as flexibility, breathability, or cushioning, thereby providing comfort and adaptability to the foot of the user.

[0071] Conversely, the second material, which constitutes the second element, may be chosen for its durability, rigidity, or enhanced grip, thereby contributing to the structural integrity and performance of the control element.

[0072] By utilizing different materials for the first and second elements, the article of footwear can achieve a synergistic effect where the first material ensures user comfort and fit, while the second material enhances the functional aspects of ball control and ankle support. This dual-material approach allows for a more tailored and specialized design, addressing specific needs of soccer players, such as improved ball handling and improved balance.

[0073] According to a preferred embodiment of the present disclosure, the discontinuous pattern comprises a plurality of first elements and a plurality of second elements, wherein the first elements and the second elements are arranged in an alternating manner.

[0074] The alternating arrangement of these elements ensures that the control element can provide enhanced grip and control over the ball while simultaneously offering structural reinforcement to the ankle portion. The first elements may be composed of a material with a higher friction coefficient to improve ball control, while the second elements could be designed to offer additional flexibility or cushioning.

[0075] This alternating pattern not only optimizes the functional aspects of the control element but also contributes to the overall durability and comfort of the article of footwear. By incorporating a discontinuous pattern with alternating first and second elements, the article of footwear achieves a balanced distribution of forces during dynamic movements such as shooting and passing. Thereby, performance may be enhanced.

[0076] In one example, the dots may be alternated in a checkerboard pattern.

[0077] According to a preferred embodiment of the present disclosure, one or more of the elongate elements are arranged in a substantially vertical alignment with respect to a ground when a user wearing the article of footwear stands on the ground, and / or one or more of the elongate elements are arranged in a substantially horizontal alignment with respect to a ground when a user wearing the article of footwear stands on the ground, and / or one or more of the elongate elements are arranged in a substantially oblique alignment so as to be between the vertical alignment and the horizontal alignment.

[0078] The vertical alignment mechanism facilitates improved structural support along the length of the foot and ankle, thereby providing enhanced stability. Additionally, this vertical configuration aids in the efficient transfer of force during activities such as running and jumping, optimizing the user's performance.

[0079] The horizontal alignment mechanism is designed to enhance the lateral support and flexibility of the footwear, allowing for better control and maneuverability during rapid lateral movements, which are common in sport activities, such as soccer. The horizontal elements also contribute to the overall comfort of the sock by distributing pressure evenly across the foot, reducing the likelihood of pressure points and blisters.

[0080] It may be conceivable that elongate elements such as lines or the like may have a main direction and they may reduce the stretch significantly in one main direction. For example, in the horizontal alignment, the stretch may be reduced around the circumference of the ankle. As a result, this may provide stability and / or the perception of it. In turn, the vertical direction may remain less affected by the stretch reduction.

[0081] The oblique alignment mechanism provides a balanced combination of vertical support and horizontal flexibility, offering a multi-directional reinforcement that is particularly beneficial for complex foot movements.

[0082] Collectively, these specific mechanisms of communication between the elongate elements and their respective alignments bring a comprehensive enhancement to the article of footwear, ensuring that it not only supports the foot and ankle effectively but also optimizes the user's performance through improved stability, flexibility, and comfort.

[0083] According to a preferred embodiment of the present disclosure, one or more of the elongate elements are substantially straight lines, and / or one or more of the elongate elements are substantially curved lines.

[0084] The straight-line configuration of the elongate elements facilitates a more uniform distribution of forces across the surface of the article of footwear, thereby enhancing the structural integrity and stability of the control element.

[0085] The curved-line configuration introduces a different set of mechanical interactions between the components of the article of footwear. Curved elongate elements can offer a more flexible and adaptive fit, conforming more naturally to the contours of the user's foot and the interior of the shoe.

[0086] According to a preferred embodiment of the present disclosure, two neighboring elongate elements of the elongate elements are spaced apart from one another by at least 2%, preferably at least 5%, preferably at least 10%, preferably at least 20%, preferably at least 30%, preferably at least 40% of a width of the two neighboring elongate elements, the width seen perpendicular to the longitudinal axis of the two neighboring elongate elements; and / or two neighboring elongate elements of the elongate elements are spaced apart from one another by at most 100%, preferably at most 90%, preferably at most 80%, preferably at most 70%, preferably at most 60%, preferably at most 50% of a width of the two neighboring elongate elements, the width seen perpendicular to the longitudinal axis of the two neighboring elongate elements.

[0087] This spacing mechanism ensures that there is a sufficient gap between the elongate elements, which can enhance the flexibility and breathability of the control element, thereby improving the overall comfort and performance of the article of footwear. Additionally, the spacing can contribute to the optimal distribution of pressure and support around the ankle, further reinforcing the ankle portion. The upper limit on the spacing ensures that the elongate elements remain close enough to each other to provide the necessary structural integrity and support required for effective ball control and ankle reinforcement.

[0088] According to a preferred embodiment of the present disclosure, the control element is formed as a separate piece, such as a separate patch or a separate textile or a separate textile fiber element, the separate piece being separate from the article of footwear.

[0089] This separation allows for greater flexibility in the design and material selection of the control element, enabling the use of materials that may offer enhanced performance characteristics such as improved grip, durability, or flexibility. This may not be feasible if the control element were to be integrally formed with the article of footwear.

[0090] A separate textile element offers several advantages. For instance, it allows for increased design flexibility, enabling the incorporation of various materials with different properties tailored to specific functions, such as moisture-wicking, breathability, or enhanced grip. Furthermore, the use of a separate textile element can enhance manufacturing efficiency by allowing distinct components to be produced separately and assembled as needed.

[0091] Furthermore, the separate patch configuration facilitates easier replacement or customization of the control element. This can be particularly advantageous for users who require different control elements for varying conditions or preferences, such as different playing surfaces or weather conditions.

[0092] In some examples, the easier replacement may be facilitated through the use of hook-and-loop fasteners, which may be referred to as Velcro. This configuration may allow for the modular adjustment of the control element on each individual foot, thereby enabling the customization of footwear according to specific user preferences or requirements. For instance, this may include distinct configurations tailored to the user's dominant foot, commonly known as the shooting foot in various sports, and the non-dominant, or weaker, foot, thereby optimizing performance characteristics specific to each foot's role.

[0093] According to a preferred embodiment of the present disclosure, the control element comprises polyurethane, in particular thermoplastic polyurethane (TPU), polyamide, thermoset elastomers, rubber, latex, foamed polymers, such as latex TPU, EVA, PEBA, PA, flock printing, leather, such as artificial or real leather, and / or silicone.

[0094] Additionally or alternatively, the control element comprises materials with dilatant properties, also known as non-Newtonian or shear-thickening materials. Incorporating materials with dilatant properties is highly advantageous. These materials have the characteristic of increasing their viscosity in response to shear strain, thereby potentially becoming more rigid under rapid or high-impact forces while remaining flexible and / or pliable under slower, less forceful movements.

[0095] Suitable materials with dilatant properties include, but are not limited to, shear-thickening fluids, thermoplastic polymers, viscoelastic foams, colloidal suspensions, and certain types of rubber compounds. The use of such materials can enhance stability during high-speed movements and / or sudden changes in direction, providing increased resistance and support. At lower speeds or during more controlled movements, the material's pliability allows for essentially natural and / or unrestricted motion. This dual functionality optimizes both performance and comfort, adapting to the dynamic needs of the user.

[0096] These materials results in a control element that not only assists with shooting and passing a ball but also reinforces the ankle portion of the article of footwear, providing additional support and stability.

[0097] For instance, polyamide and thermoset elastomers contribute to the structural integrity and elasticity of the control element, allowing it to conform to the shape of the foot while providing robust support.

[0098] Rubber and latex materials offer additional grip and traction, which are crucial for controlling the ball during play.

[0099] Foamed polymers such as latex TPU, EVA, PEBA, and PA provide cushioning and shock absorption, reducing the strain on the user's foot and enhancing comfort.

[0100] According to a preferred embodiment of the present disclosure, the control element is applied to the article of footwear in liquid form.

[0101] A liquid TPU application process allows to achieve a 3D structure, for example, pyramids or longer columns. This may be understood as a 3D print on a sock or the like. For instance, this may not necessarily be performed by way of a single layer application, but by way of more than one layer application.

[0102] According to a preferred embodiment of the present disclosure, application of the control element to the article of footwear comprises providing a polymer, a solvent, mixing the same, and curing the mixture on the article of footwear.

[0103] The polymer may serve as the foundational material for the control element. Additionally, the application process includes providing a solvent, which acts as a medium to facilitate the even distribution and proper adhesion of the polymer to the article of footwear. Furthermore, the process involves mixing the polymer and the solvent, creating a homogenous mixture that optimizes the properties of both components. This mixture ensures that the control element is uniformly applied, providing consistent performance across the entire surface of the article of footwear.

[0104] The curing process solidifies the mixture, ensuring that the control element is firmly attached to the sock and capable of withstanding the rigors of soccer play.

[0105] According to a preferred embodiment of the present disclosure, the control element comprises one or more layers.

[0106] The inclusion of multiple layers within the control element allows for a more nuanced and effective interaction with the ball, thereby enhancing the user's ability to shoot and pass with greater precision and control.

[0107] Each layer can be designed with specific materials and properties that contribute to the overall functionality of the control element. For instance, an outermost layer might be composed of a high-friction material to improve grip on the ball, while an inner layer could be made of a more flexible, cushioning material to absorb impact and provide comfort to the user's foot.

[0108] According to a preferred embodiment of the present disclosure, the one or more layers have varying thicknesses.

[0109] The varying thicknesses of the layers serve multiple purposes and introduce several new features to the article of footwear.

[0110] For instance, the varying thicknesses can provide differential cushioning and support to different parts of the foot, enhancing comfort and improving balance during vigorous activities such as playing soccer.

[0111] Thicker layers could be strategically placed in high-impact areas to absorb shock, while thinner layers could be used in areas requiring more flexibility and breathability.

[0112] Moreover, the varying thicknesses can contribute to the overall functionality of the control element. By incorporating layers of different thicknesses, the control element can be fine-tuned to offer optimal resistance and support, thereby improving the user's ability to control the ball during shooting and passing.

[0113] According to a preferred embodiment of the present disclosure, the control element comprises one or more yarns configured to interlock with the outside shoe portion.

[0114] The interlocking enhances the overall functionality and durability of the article of footwear.

[0115] The inclusion of yarns as part of the control element provides a more secure and stable connection between the control element and the outside shoe portion. This may ensure that the control element remains in place during activities such as playing soccer.

[0116] This stability may be important for maintaining the effectiveness of the control element in assisting with shooting and / or passing a ball, as any displacement or movement of the control element could diminish its intended performance.

[0117] The use of yarns may additionally or alternatively allow for a degree of flexibility and adaptability in the control element, enabling it to conform to the natural movements of the foot and ankle.

[0118] According to a preferred embodiment of the present disclosure, the control element is formed integrally with the article of footwear.

[0119] The integration of the control element directly into the fabric or material of the footwear eliminates the need for additional attachment mechanisms such as stitching, adhesives, or other forms of bonding, which can often introduce points of weakness or discomfort.

[0120] By being integrally formed, the control element becomes an inherent part of the footwear's construction, ensuring a seamless interface that enhances the overall durability and longevity of the product.

[0121] The seamless integration not only improves the structural integrity but also enhances functionality by providing a smooth, uninterrupted surface. Furthermore, this embodiment can contribute to a reduction in manufacturing complexity and cost, as it consolidates multiple production steps into a single process.

[0122] According to a preferred embodiment of the present disclosure, the control element comprises a microtextured surface, preferably on an outer surface of the control element.

[0123] The microtextured surface described in here is to be distinguished from, e.g., surfaces, which reveal macro elements, e.g., macro protrusions. These macro protrusions are believed to interfere with dribbling.

[0124] The microtextured surface introduces an enhanced tactile interaction and grip during ball handling. This microtextured surface is preferably located on an outer surface of the control element, which strategically positions the enhanced grip where it is most effective during play.

[0125] The inclusion of the microtextured surface on the outer surface of the control element improves the player's control over the ball by increasing friction between the ball and the foot. This may facilitate more precise and controlled movements during shooting and passing.

[0126] Further, the microtextured surface contributes to the overall durability and wear resistance of the control element, as the textured design can help distribute stress and reduce wear in high-contact areas.

[0127] Furthermore, the microtextured surface on the outer surface of the control element can provide additional reinforcement to the ankle portion of the article of footwear, as the textured material may offer increased structural integrity and support.

[0128] According to a preferred embodiment of the present disclosure, the microtextured surface comprises a plurality of protrusions.

[0129] The plurality of protrusions on the microtextured surface provides additional friction and grip, thereby improving the user's ability to manipulate the ball with precision during play.

[0130] This interaction ensures that the control element can function more effectively by leveraging the increased surface area and texture provided by the protrusions.

[0131] The protrusions may have any shape including but not limited to a pillar shape. Further examples of shapes encompassed by the present disclosure may be spikes, knobs, ridges, tendrils, bumps, spines, tubercles, crests, and / or prongs. The protrusions may have a variety of cross-sectional shapes, including but not limited to circles, squares, rectangles, ovals, triangles, hexagons, pentagons, stars, and ellipses.

[0132] The arrangement and placement of the protrusions can be meticulously designed to enhance the performance of the article of footwear during activities such as shooting and passing a ball.

[0133] The protrusions may be elastically bendable. The elastically bendable nature of each protrusion may help in extending the contact time between the shoe and the ball, thereby providing better control and precision. This design may address the challenge of maintaining consistent ball control under varying conditions, such as different ball speeds and angles of contact. For instance, when a ball contacts the microstructure surface, the protrusions may bend elastically, providing a controlled deformation that aids in the manipulation of the ball. This elastic bending is facilitated by the material properties and structural design of the protrusions.

[0134] According to a preferred embodiment of the present disclosure, one or more of the plurality of protrusions, preferably each protrusion of the plurality of protrusions comprises an aspect ratio defined by a height of a protrusion compared to a width of the protrusion of at least 1.1, preferably at least 1.2, preferably at least 1.3, preferably at least 1.4, preferably at least 1.5; and / or of at most 10, preferably at most 8, preferably at most 6, preferably at most 4, preferably at most 3.

[0135] The geometric relationship between the height and width of each protrusion may directly influence the aspect ratio. This geometric relationship ensures that the protrusions maintain a specific shape and size, which may be beneficial for their elastic bendability and overall functionality.

[0136] The introduction of these specific aspect ratio ranges brings several advantages to the article of footwear. Firstly, by defining the aspect ratio to be within a certain range, the protrusions are optimized for their intended function of assisting with shooting and / or passing a ball. The specified aspect ratios ensure that the protrusions are neither too short and wide nor too tall and narrow, which could compromise their elastic properties and effectiveness.

[0137] A higher aspect ratio within the defined range ensures that the protrusions have sufficient height to interact effectively with the ball, while the width is controlled to maintain stability and prevent excessive bending or deformation. This balance enhances the tactile feedback and control a player experiences when making contact with the ball, thereby improving performance in sports activities.

[0138] Additionally, the preferred ranges for the aspect ratio provide flexibility in design while ensuring that the protrusions remain within an optimal functional range. This allows for variations in manufacturing processes and materials without compromising the performance characteristics of the article of footwear.

[0139] Overall, the introduction of these specific aspect ratio ranges enhances the functionality, performance, and versatility of the article of footwear, making it more effective for sports applications.

[0140] According to a preferred embodiment of the present disclosure, one or more of the plurality of protrusions, preferably each protrusion of the plurality of protrusions comprises a width of at least 0.05 mm, preferably at least 0.08 mm, preferably at least 0.1 mm; and / or of at most 1.0 mm, preferably at most 0.7 mm, preferably at most 0.5 mm, preferably at most 0.3 mm.

[0141] The specified minimum width ensures that the protrusions are robust enough to withstand repeated contact with the ball without breaking or deforming permanently.

[0142] Furthermore, this embodiment ensures that the protrusions are not excessively wide, which could otherwise hinder their ability to bend elastically and negatively impact the tactile feedback and control provided to the user. By defining an upper limit on the width, this feature maintains the balance between flexibility and structural integrity, allowing the protrusions to bend elastically upon contact with the ball, thereby enhancing the user's ability to control the ball during play.

[0143] The protrusions, being within the defined width range, are able to bend elastically and provide a controlled response upon contact with the ball, thereby assisting with shooting and passing. This controlled response may be a direct result of the specified dimensions, which ensure that the protrusions are neither too thin to be fragile nor too thick to be inflexible.

[0144] Thus, the new features introduced by this embodiment bring about a precise and optimized structural configuration of the protrusions, enhancing the overall functionality and performance of the upper in assisting with ball control during sports activities.

[0145] According to a preferred embodiment of the present disclosure, the control element is arranged in an ankle portion of the article of footwear, in particular a medial ankle portion and / or a lateral ankle portion of the article of footwear, and / or an instep portion of the article of footwear.

[0146] When the control element is arranged in an ankle portion of the article of footwear, it provides targeted reinforcement to the ankle area, which can enhance stability and support during dynamic movements such as shooting and passing a ball. This specific placement ensures that the control element directly contributes to the structural integrity of the ankle, thereby improving overall performance.

[0147] Furthermore, when the control element is arranged in a medial ankle portion of the article of footwear, it offers additional benefits by focusing the reinforcement on the inner side of the ankle. This medial placement can be particularly advantageous for soccer players who frequently use the inner part of their foot for ball control, passing, and shooting. By reinforcing the medial ankle, the control element can provide enhanced support and control, which can lead to more precise and powerful ball handling.

[0148] Moreover, when the control element is positioned in the lateral ankle portion of the article of footwear, it provides beneficial stability by reinforcing the outer side of the ankle. This lateral placement may be particularly advantageous for activities that require significant lateral movements or stability, such as sudden direction changes or lateral maneuvers in sports. By reinforcing the lateral ankle, the control element offers enhanced stability and support, thereby improving the user's balance. This can contribute to more effective and controlled movement.

[0149] Additionally, when the control element is arranged in an instep portion of the article of footwear, it serves to reinforce the area of the foot that is often used for striking the ball. The instep may be a critical area for generating power and accuracy in shots and passes. By incorporating the control element in the instep portion, the article of footwear can assist in improving the user's ability to strike the ball with greater force and precision.

[0150] The strategic placement of the control element in these various portions demonstrates a thoughtful design approach aimed at maximizing the utility and effectiveness of the article of footwear for soccer players.

[0151] According to a preferred embodiment of the present disclosure, the inside shoe portion comprises a further control element, preferably a further control element according to any preceding embodiments.

[0152] It is to note that also combinations of different patterns on the inside shoe portion and / or the outside shoe portion are encompassed according to the present disclosure. For instance, a pattern comprising one or more dots for wet / dry grip may be provided on the outside shoe portion and / or a pattern comprising one or more lines may be provided on the inside shoe portion. The latter one may restrict stretch on the inside shoe portion as described elsewhere in here.

[0153] Moreover, this further control element is preferably designed to complement the control element of the outside shoe portion, thereby providing a synergistic effect that enhances the overall performance of the article of footwear.

[0154] The inclusion of the further control element in the inside shoe portion may provide additional support and control to the user. This dual control system, comprising both the inside and outside control elements, ensures that the user has better grip, stability, and precision when handling the ball, whether for shooting, passing, or other soccer-related maneuvers.

[0155] According to a preferred embodiment of the present disclosure, the control element covers an area of at least 2%, preferably at least 5%, preferably at least 10%, preferably at least 20%, preferably at least 30%, preferably at least 40% of the article of footwear; and / or the control element covers an area of at most 95%, preferably at most 90%, preferably at most 80%, preferably at most 70%, preferably at most 60%, preferably at most 50% of the article of footwear.

[0156] This feature introduces a specific quantitative measure of the control element's coverage, ensuring that a minimum portion of the article of footwear is dedicated to the control element. This enhances the functional aspects of the control element by ensuring sufficient surface area to effectively assist with ball control and ankle reinforcement. This aids in ensuring that the control element is not merely a small, insignificant part but a substantial component that contributes meaningfully to the overall performance of the article of footwear.

[0157] Further, by setting an upper limit, this feature maintains the balance between the control element and other functional aspects of the article of footwear. This may be due to the limitation of the control element's spread, ensuring that other parts of the article of footwear, such as those providing comfort, breathability, or additional support, are not compromised.

[0158] According to a preferred embodiment of the present disclosure, the control element comprises a height of at least 0.1 mm, preferably at least 0.2 mm, preferably at least 0.3 mm, preferably at least 0.4 mm; and / or of at most 8 mm, preferably at most 6 mm, preferably at most 4 mm, preferably at most 3 mm, preferably at most 2 mm, preferably at most 1.5 mm, preferably at most 1.2 mm, preferably at most 1.0 mm, preferably at most 0.8 mm.

[0159] The minimal height ensures that the control element is sufficiently prominent to provide tactile feedback and improve ball control.

[0160] Conversely, setting the height of the control element to a maximum ensures that it does not become excessively bulky, which could interfere with the fit of the article of footwear within a shoe.

[0161] These specific height parameters of the control element may be important in optimizing the functional performance of the article of footwear, ensuring that it provides the necessary support and control without compromising comfort or fit.

[0162] By carefully calibrating the height of the control element, the article of footwear achieves a harmonious integration of enhanced ball control, ankle reinforcement, and overall wearability, making it particularly suitable for soccer players seeking to improve their performance on the field.

[0163] According to a preferred embodiment of the present disclosure, the control element comprises a maximum dimension in a direction along the surface of the article of footwear of at least 2 mm, preferably at least 5 mm, preferably at least 10 mm, preferably at least 20 mm, preferably at least 40 mm, preferably at least 60 mm, preferably at least 80 mm; and / or of at most 200 mm, preferably at most 180 mm, preferably at most 160 mm, preferably at most 140 mm, preferably at most 120 mm.

[0164] A control element with a maximum dimension of at least 2 mm provides a minimal yet sufficient surface area to enhance ball control and ankle reinforcement. As the dimension increases to at least 5 mm, 10 mm, 20 mm, 40 mm, 60 mm, and 80 mm, the control element progressively offers greater surface area, thereby potentially increasing the effectiveness of ball control and the structural support provided to the ankle.

[0165] Conversely, specifying maximum dimensions of at most 200 mm, 180 mm, 160 mm, 140 mm, and 120 mm ensures that the control element does not become excessively large, which could otherwise hinder the flexibility and comfort of the article of footwear. Further, the upper limits maintain a balance between functionality and wearability, ensuring that the control element remains effective without compromising the overall design and comfort of the sock.

[0166] According to a preferred embodiment of the present disclosure, the article of footwear is a sock, in particular a sock used for playing soccer.

[0167] The sock inherently implies a close-fitting, flexible, and typically elastic material designed to conform snugly to the contours of the foot.

[0168] It goes without saying that the technical properties shown or described for the article of footwear, the advantages and the improvements over the state of the art are likewise applicable to the sock, in particular a sock used for playing soccer.4. Brief description of the figures

Common parts of each embodiment will be described first before describing individual parts of each embodiment. Nonetheless, the skilled person understands that these are merely examples and combinations of features shown in one embodiment may be another embodiment as far as this is technically feasible.

[0180] The embodiments show an article of footwear 100, such as a sock or a calf sleeve, in particular a sock or a calf sleeve used for playing soccer, the article of footwear 100 configured to be worn by a foot of a user and then to be received in a shoe 50. The article of footwear 100 comprises an inside shoe portion 105 and an outside shoe portion 110. The outside shoe portion 110 comprises a control element 130. The control element 130 is configured to assist with shooting and / or passing and / or receiving a ball and further configured to reinforce an ankle portion 120 of the article of footwear 100.

[0181] As described elsewhere herein, the article of footwear 100 aims to address the shortcomings of the prior art by introducing a targeted control element 130 which may comprise one or more grip elements, the control element 130 being - in one example - arranged in a medial ankle portion of the article of footwear 100. In preferred embodiments, the control element 130, specifically the grip elements, can be applied using various materials, including liquid TPU, rubber, silicone, and micro-texture films, to create a 3D structure that enhances grip and stability. The invention also considers the application of these materials in specific patterns, such as plain surfaces, dots, lines, or grid patterns, to maximize ball control and player proprioception.

[0182] By focusing on the portions of the article of footwear 100 that come into contact with the ball, the invention provides in particular soccer players with improved ball reception and control, regardless of environmental conditions. The enhanced grip features also contribute to a perceived increase in ankle stability, further supporting the player's performance on the field.

[0183] The outside shoe portion 110 may be at least partially exposed to an exterior when the article of footwear 100 is worn by a foot of a user and then received in a shoe 50.

[0204] As can be seen in the embodiments of Fig. 3, the discontinuous pattern preferably comprises one or more, preferably a plurality of elongate elements 135, in particular lines.

[0205] As best seen in the left and middle picture of Fig. 3, one or more of the elongate elements 135 may be arranged in a substantially vertical alignment with respect to a ground when a user wearing the article of footwear 100 stands on the ground.

[0206] As best seen in the right picture of Fig. 3, one or more of the elongate elements 135 are arranged in a substantially horizontal alignment with respect to a ground when a user wearing the article of footwear 100 stands on the ground.

[0207] Further, it is also encompassed in the present disclosure that one or more of the elongate elements 135 may be arranged in a substantially oblique alignment so as to be between the vertical alignment and a horizontal alignment.

[0212] The right part of Fig. 5 shows an exemplary article of footwear 100, such as a sock or a calf sleeve, in particular a sock or a calf sleeve used for playing soccer, according to an embodiment of the present disclosure. The control element 130 may be arranged in a pattern. The pattern comprises a continuous pattern, similar to the embodiment of Fig. 1. The control element 130 in the right part of Fig. 5 may be formed as a separate piece, preferably as a separate patch, separate from the article of footwear 100.

[0213] As described elsewhere herein, the control element 130 is configured to assist with shooting and / or passing and / or receiving a ball. In this respect, it is to note that shooting and passing as referred to in here may comprise any possible action in which the player arranges the article of footwear 100 such that when worn by a foot gets in contact with the ball. Shooting as referred to in here may mean that the player is striking, e.g., shooting with a rather fast foot movement to a goal. In particular, shooting may comprise strong striking shots, such as a power shot, i.e., a shot struck with maximum force, often used for long-range attempts. Another example may be a volley, i.e., a shot taken directly out of the air, generating significant power. Another example may be a half-volley, i.e., a shot struck just as the ball is bouncing off the ground, allowing for a powerful strike. Another example may be a free kick (when struck with power), i.e., a direct shot on goal from a set-piece situation, hit with significant force. Another example may be a penalty kick (when struck with power), i.e., a shot taken from the penalty spot, often hit with great power to beat the goalkeeper.

[0214] Passing as referred to in here may comprise less powerful actions (like passing, dribbling, and first touches). In particular, passing may comprise dribbling, i.e., moving the ball with a series of controlled touches, often focusing on maneuverability rather than power. Another example may be a first touch, i.e., the initial touch used to control the ball, emphasizing precision and control. Another example may be a placed shot, i.e., a shot focused on accuracy, aiming to place the ball out of the goalkeeper's reach. Another example may be a chip shot, i.e., a delicate shot intended to loft the ball over the goalkeeper with minimal power. Another example may be a side-footed shot, i.e., a controlled and accurate shot using the side of the foot, typically less powerful.

[0215] It is noted that any one or more of the embodiments described herein and / or examples may be combined with further aspects as described herein and details of the embodiments and / or examples may also be omitted, as will be understood by the skilled person. The scope of protection is determined by the claims and is not limited by the embodiments and / or examples disclosed in the above figures.6. Further embodiments
