[0057] The present disclosure is related to 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 and further configured to reinforce an ankle portion of the article of footwear.
[0058] In some embodiments, the article of footwear may provide a control element that allows for improved functionality, namely, to assist with shooting and/or passing a ball.
[0059] As describes elsewhere herein, this improved functionality 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, the article of footwear may facilitate increasing an area than can make contact with a ball, for example during playing soccer. The advantages of the shoe are not deteriorated thereby. Hence, the article of footwear can function in synergy with the shoe.
[0060] In some embodiments, the outside shoe portion may include 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 may be 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.
[0061] 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.
[0062] 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 increasing the effectiveness of the control element. In some embodiments, 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 article of footwear, 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.
[0063] 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 may not only enhance the overall performance of the user, but also address the need for durability and comfort in soccer socks, making it a comprehensive solution for soccer players. The inside shoe portion may not necessarily be limited to be completely within the 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.
[0064] In some embodiments, 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.
[0065] 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 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, etc. 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, weightlifting, cross-training, baseball, softball, rugby, field hockey, wrestling, squash, track and field (such as sprinting, long jump, high jump), cross-country skiing, etc.
[0066] 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.
[0067] In some embodiments, the article of footwear may 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.
[0068] The above-mentioned advantages are also applicable to the following embodiments.
[0069] According to some embodiments of the present disclosure, the outside shoe portion may be 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.
[0070] 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 outside shoe portion to the exterior allows the control element, which may be part of the outside shoe portion, to interact directly with external elements such as a soccer ball. This may enhance 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.
[0071] Additionally, the exposure of the outside shoe portion to the exterior while the article of footwear is within a shoe may ensure that the reinforcement provided to the ankle portion is not compromised by the shoe's structure. This dual functionalityenhanced ball control and ankle supportmay provide a significant advantage to the user, particularly in the context of soccer where both precise ball handling and ankle stability are critical.
[0072] According to some embodiments of the present disclosure, the control element may be arranged on an outer surface of the outside shoe portion.
[0073] By situating the control element on the outer surface, the design may ensure that the control element is exposed to the external environment, thereby optimizing its functional interaction with a soccer ball during play. This arrangement of the control element may enhance 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 article of footwear, ensuring that it may not interfere with the comfort or fit of the article of footwear when worn inside a shoe.
[0074] According to some embodiments of the present disclosure, the control element may be configured to increase a grip between the article of footwear and a ball.
[0075] In some embodiments, 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 may 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 the enhanced grip may enhance the user's ability to control the ball during play, providing better precision and accuracy in shooting and passing. Further, the enhanced grip may 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, which may result in more powerful and controlled kicks. Moreover, the reinforcement of the ankle portion, as mentioned elsewhere herein, is complemented by the enhanced grip, as the enhanced grip ensures that the foot remains stable within the shoe, improving balance and enhancing overall comfort. Additionally, the enhanced 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.
[0076] 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 conditions (for example, when the ground is wet due to rain, sprinklers, dew, etc.) and dry conditions at the same time.
[0077] According to some embodiments of the present disclosure, the control element may comprise a single material, wherein the control element may be configured to provide a first grip force between the article of footwear and a ball under wet conditions and a second grip force between the article of footwear and a ball under dry conditions, wherein the first grip force and the second grip force deviate by at most 50%, at most 40%, at most 30%, at most 20%, or at most 10% of the second grip force.
[0078] The described feature of the article of footwear offers several advantages:
[0079] By comprising a single material, the control element may simplify the manufacturing process. This simplification may lead to cost savings in production and may 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 by eliminating areas where different materials meet. A single material construction may therefore be more robust than a construction with multiple materials that are coupled.
[0080] In some embodiments, the control element may provide 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 receiving 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% ensures that the athlete experiences minimal changes in grip when the conditions change. This consistency can improve performance and reduce the risk of slips or falls. This improved performance may be even more pronounced when the difference is only 40% and/or only 10%.
[0081] 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.
[0082] According to some embodiments of the present disclosure, the control element may be arranged in a pattern.
[0083] This patterned arrangement may 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 may 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 may 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 the control element is not randomly and/or haphazardly placed, but rather strategically positioned to maximize its effectiveness in assisting with ball control and reinforcing the ankle.
[0084] According to some embodiments of the present disclosure, the pattern comprises a connected pattern and/or a continuous pattern, and/or a discontinuous pattern.
[0085] The connected pattern may facilitate 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.
[0086] The continuous pattern may ensure that the control element extends uninterrupted, e.g., over a significant portion (for example at least 20%, at least 30%, at least 40%, etc.) of the outside shoe portion. This may maximize the area of contact with the ball during shooting and/or passing. This maximized contact area may enhance the user's control over the ball, leading to more precise and powerful shots and passes.
[0087] 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. For example, such patterns may be beneficial to dial in stretch properties in case more or less is needed.
[0088] 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 of the article of footwear, accommodating the natural motion of the foot and ankle during dynamic activities such as soccer. Additionally, the discontinuous pattern may aid in moisture management by allowing air to circulate more freely through the article of footwear, thereby keeping the foot cooler and drier during play.
[0089] In some embodiments, the continuous pattern may comprise a plain pattern. The discontinuous pattern may comprise an interrupted pattern.
[0090] According to some embodiments of the present disclosure, the connected pattern may comprise 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, or a combination thereof.
[0091] In some embodiments, the connected pattern comprising a grid pattern may introduce 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.
[0092] The hexagonal pattern may offer 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.
[0093] The honeycomb pattern, known for its strength and lightweight properties, may provide robust support while minimizing additional weight, thus maintaining agility and speed.
[0094] The triangular pattern, with its geometric stability, may offer superior resistance to deformation, ensuring that the control element maintains its shape and effectiveness over time.
[0095] The circular pattern may have the advantage of providing a more dynamic and responsive reinforcement.
[0096] The network pattern, characterized by interconnected nodes and links, may offer a combination of flexibility and strength, ensuring that the control element can adapt to various stresses while providing consistent support.
[0097] The spiral pattern may introduce a unique mechanism of distributing forces in a radial manner, which can enhance the overall balance and control of the foot during complex maneuvers.
[0098] The radial pattern, which may emanate from a central point, may provide a focused reinforcement that supports the ankle from multiple directions, improving stability and may reducing the risk of injury.
[0099] The lattice pattern, which may comprise crisscrossing elements, may 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.
[0100] 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.
[0101] According to some embodiments of the present disclosure, the continuous pattern may comprise a single closed surface.
[0102] This may have the advantage of restricting the stretch of the article of footwear in all directions. Restricting the stretch of the article of footwear may provide for a constraining feeling around the ankle of the wearer. This constraining feeling may lead to a perceivable support of the ankle, appreciated by the wearer.
[0103] 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.
[0104] Additionally, the single closed surface of the continuous pattern may facilitate 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.
[0105] Furthermore, the continuous pattern may enhance the tactile feedback experienced by the user, as the uniform surface can provide a predictable and controlled interaction with the ball. This can lead to improved performance in terms of ball control and accuracy during play.
[0106] Notably, the friction between ball and a closed surface may be expected to be high in this embodiment (for example, higher than the friction between the ball and an article of footwear without a closed surface). Additionally, the portion of the article of footwear having the closed surface may be stiffer than a similar portion of an article of footwear without the closed surface.
[0107] According to some embodiments of the present disclosure, the discontinuous pattern may comprise one or more elements, for example a plurality of elements, wherein each element may comprise a distinct boundary, wherein the discontinuous pattern may comprise one or more (for example a plurality of) dots, and/or elongate elements, such as lines.
[0108] In some embodiments, the distinct boundary of each element within the discontinuous pattern may ensure that the control element can effectively interact with the ball, providing precise feedback and control during play.
[0109] In some embodiments, the discontinuous pattern may comprise one or more dots, for example a plurality of dots, which may be strategically placed to optimize control and reinforcement.
[0110] In some embodiments, the discontinuous pattern may comprise one or more elongate elements, for example a plurality of elongate elements, which may comprise lines. In some embodiments, the elongate elements may 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.
[0111] In some embodiments, the incorporation of dots and/or elongate elements in a discontinuous pattern may allow for targeted reinforcement and flexibility, ensuring that the article of footwear can adapt to the dynamic movements required in soccer.
[0112] In some embodiments, the elongate elements may offer a streamlined design that can distribute pressure evenly across the ankle portion, thereby improving overall comfort.
[0113] According to some embodiments of the present disclosure, a first element of the plurality of elements may comprise a first material and a second element of the plurality of elements may comprise a second material, wherein the second material is different than the first material. Similarly, in some embodiments of the present disclosure, a first dot of the plurality of dots may comprise a first material and a second dot of the plurality of dots may comprise a second material, wherein the second material is different than the first material.
[0114] The use of different materials has the advantage of providing targeted functionality. For instance, the first material may be provided to cater for wet conditions and the second material may be provided to cater for dry conditions.
[0115] In some embodiments, using two materials may 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.
[0116] In some embodiments, the first material, which may be associated with the first element, may be selected for properties such as flexibility, breathability, and/or cushioning, thereby providing comfort and adaptability to the foot of the user.
[0117] In some embodiments, the second material, which may be associated with the second element, may be chosen for its durability, rigidity, and/or enhanced grip, thereby contributing to the structural integrity and performance of the control element.
[0118] In some embodiments, by utilizing different materials for the first and second elements, the article of footwear may achieve a synergistic effect where the first material may ensure user comfort and fit, while the second material may enhance the functional aspects of ball control and ankle support. This dual-material approach may allow for a tailored and specialized design, addressing specific needs of soccer players, such as improved ball handling and improved balance.
[0119] According to some embodiments of the present disclosure, the discontinuous pattern may comprise 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.
[0120] The alternating arrangement of these elements may ensure that the control element can provide enhanced grip and control over the ball while simultaneously offering structural reinforcement to the ankle portion. In some embodiments, the first element may be composed of a material with a higher friction coefficient to improve ball control, while the second element may offer additional flexibility or cushioning.
[0121] This alternating pattern not only may optimize the functional aspects of the control element, but may also contribute 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 may achieve a balanced distribution of forces during dynamic movements such as shooting and passing. Thereby, performance may be enhanced.
[0122] In an example embodiment, the dots may be alternated in a checkerboard pattern. For example, a first group of dots may comprise a first material (for example, a material associated with comfort and durability), and a second group of dots may comprise a second material (for example, a higher friction material), and the arrangement of dots may comprise an alternating pattern of first dots and second dots. Such an arrangement may provide enhanced grip and control over the ball while simultaneously offering flexibility and cushioning.
[0123] According to some embodiments of the present disclosure, one or more of the elongate elements may be 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 may be 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 may be arranged in a substantially oblique alignment so as to be between the vertical alignment and the horizontal alignment.
[0124] In some embodiments, the substantially vertical alignment may facilitate improved structural support along the length of the foot and ankle, thereby providing enhanced stability. Additionally, this substantially vertical alignment may aid in the efficient transfer of forces during activities such as running and jumping, optimizing the user's performance.
[0125] In some embodiments, the substantially horizontal alignment may enhance the lateral support and flexibility of the article of footwear, allowing for better control and maneuverability during rapid lateral movements, which are common in sport activities, such as soccer. The substantially horizontal alignment of elements may also contribute to the overall comfort of the sock by distributing pressure evenly across the foot, reducing the likelihood of pressure points and blisters.
[0126] In some embodiments, the elongate elements may have a main direction and they may reduce the stretch in the main direction. For example, in the horizontal alignment, the stretch may be reduced around the circumference of the ankle. In some embodiments, the reduced stretch may provide stability and/or the perception of stability. In turn, the vertical direction may remain less affected by the stretch reduction.
[0127] In some embodiments, the substantially oblique alignment may provide a balanced combination of vertical support and horizontal flexibility, offering a multi-directional reinforcement that may be beneficial for complex foot movements.
[0128] Collectively, the arrangements of the elongate elements and their respective alignments disclosed herein may bring a comprehensive enhancement to the article of footwear, ensuring that the article of footwear not only supports the foot and ankle effectively but also may optimize the user's performance through improved stability, flexibility, and comfort.
[0129] According to some embodiments of the present disclosure, one or more of the elongate elements may be substantially straight lines, and/or one or more of the elongate elements may be substantially curved lines.
[0130] The straight line configuration of the elongate elements may facilitate 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.
[0131] The curved line configuration of the elongate elements may introduce a different set of mechanical interactions between the components of the article of footwear as compared to the straight line configuration. In some embodiments, the curved elongate elements may offer a more flexible and adaptive fit, conforming more naturally to the contours of the user's foot and the interior of the shoe.
[0132] According to some embodiments of the present disclosure, two neighboring elongate elements of the elongate elements may be spaced apart from one another by at least 2%, at least 5%, at least 10%, at least 20%, at least 30%, or at least 40% of a width of the two neighboring elongate elements, the width being perpendicular to a longitudinal axis of the two neighboring elongate elements; and/or two neighboring elongate elements of the elongate elements may be spaced apart from one another by at most 100%, at most 90%, at most 80%, at most 70%, at most 60%, or at most 50% of a width of the two neighboring elongate elements, the width being perpendicular to the longitudinal axis of the two neighboring elongate elements.
[0133] In some embodiments, the spacing between the neighboring elongate elements may ensure that there is a sufficient gap between the elongate elements, which may enhance the flexibility and breathability of the control element, thereby improving the overall comfort and performance of the article of footwear. Additionally, the spacing between the neighboring elongate elements may contribute to the distribution of pressure and support around the ankle, further reinforcing the ankle portion. The upper limit on the spacing may ensure 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.
[0134] According to some embodiments of the present disclosure, the control element may 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.
[0135] In some embodiments, forming the control element as a separate piece may allow 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.
[0136] In some embodiments, forming the control element as a separate textile element may offer 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.
[0137] In some embodiments, forming the control element as a separate patch may facilitate replacement or customization of the control element. For example, the separate patch may be removably coupled to the article of footwear such that different patches may be coupled to the article of footwear for different purposes. This may be particularly advantageous for users who require different control elements for varying conditions or preferences, such as different playing surfaces or weather conditions.
[0138] In some examples, the replacement of the separate patch 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.
[0139] According to some embodiments of the present disclosure, the control element may comprise polyurethane, 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.
[0140] Additionally or alternatively, the control element may comprise materials with dilatant properties, also known as non-Newtonian or shear-thickening materials. Incorporating materials with dilatant properties may be advantageous because 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 (for example, shooting a ball) while remaining flexible and/or pliable under slower, less forceful movements (for example, during jogging or walking).
[0141] Suitable materials with dilatant properties may 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 may allow for natural and/or unrestricted motion. This dual functionality may optimize both performance and comfort, adapting to the dynamic needs of the user.
[0142] Using the materials described herein may result 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.
[0143] For instance, polyamide and thermoset elastomers may contribute to the structural integrity and elasticity of the control element, allowing the control element to conform to the shape of the foot while providing robust support.
[0144] Rubber and latex materials may offer additional grip and traction, which are crucial for controlling the ball during play.
[0145] Foamed polymers such as latex TPU, EVA, PEBA, and PA may provide cushioning and shock absorption, which may reduce the strain on the user's foot and enhance comfort.
[0146] According to some embodiments of the present disclosure, the control element may be applied to the article of footwear in liquid form.
[0147] In some embodiments, a liquid TPU application process may 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 applying a plurality of layers on top of each other to achieve the desired structure.
[0148] According to some embodiments of the present disclosure, application of the control element to the article of footwear may comprise providing a polymer, a solvent, mixing the same, applying the mixture to the article of footwear in a desired shape and/or geometry, and curing the mixture on the article of footwear.
[0149] In some embodiments, the polymer may serve as the foundational material for the control element. Additionally, the application process may comprise 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 may comprise 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.
[0150] In some embodiments, the curing process solidifies the mixture on the article of footwear, ensuring that the control element is firmly attached to the sock and capable of withstanding the rigors of soccer play. In some embodiments, the mixture may cure in ambient temperatures. In some embodiments, the mixture may cure in elevated temperatures.
[0151] According to some embodiment of the present disclosure, the control element may comprise one or more layers.
[0152] The inclusion of multiple layers within the control element may allow 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.
[0153] For example, 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 may comprise a high-friction material to improve grip on the ball, while an inner layer may comprise a more flexible, cushioning material to absorb impact and provide comfort to the user's foot.
[0154] According to some embodiments of the present disclosure, the one or more layers may have varying thicknesses.
[0155] In some embodiments, the varying thicknesses of the layers may serve multiple purposes and introduce several new features to the article of footwear.
[0156] For instance, the varying thicknesses may provide differential cushioning and support to different parts of the foot, enhancing comfort and improving balance during vigorous activities such as playing soccer.
[0157] In some embodiments, 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.
[0158] In some embodiments, the varying thicknesses may contribute to the overall functionality of the control element. By incorporating layers of different thicknesses, the control element may be fine-tuned to offer optimal resistance and support, thereby improving the user's ability to control the ball during shooting and passing.
[0159] According to some embodiments of the present disclosure, the control element may comprise one or more yarns configured to interlock with the outside shoe portion.
[0160] The interlocking may enhance the overall functionality and durability of the article of footwear.
[0161] In some embodiments, the inclusion of yarns as part of the control element may provide 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.
[0162] 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.
[0163] The use of yarns may additionally or alternatively allow for a degree of flexibility and adaptability in the control element, enabling the control elements to conform to the natural movements of the foot and ankle.
[0164] According to some embodiments of the present disclosure, the control element may be formed integrally with the article of footwear (for example, the control element and the article of footwear may comprise a unitary structure).
[0165] The integration of the control element directly into the fabric or material of the footwear may reduce or eliminate the need for additional attachment mechanisms such as stitching, adhesives, or other forms of bonding, which may introduce points of weakness or discomfort.
[0166] By being integrally formed, the control element may become an inherent part of the footwear's construction, which may ensure a seamless interface that may enhance the overall durability and longevity of the product.
[0167] The seamless integration may not only improve the structural integrity, but may also enhance functionality by providing a smooth, uninterrupted surface. Furthermore, integrally forming the control element with the article of footwear can contribute to a reduction in manufacturing complexity and cost, as it consolidates multiple production steps into a single process.
[0168] According to some embodiments of the present disclosure, the control element may comprise a microtextured surface, for example on an outer surface of the control element.
[0169] The microtextured surface described herein is to be distinguished from, for example, surfaces having macro elements such as macro protrusions. These macro protrusions may interfere with dribbling, whereas the microtextured surface described herein may aid dribbling.
[0170] For example, the microtextured surface may introduce an enhanced tactile interaction and grip during ball handling. In some embodiments, the microtextured surface may be located on an outer surface of the control element, which strategically positions the enhanced grip where it is most effective during play.
[0171] The inclusion of the microtextured surface on the outer surface of the control element may improve the player's control over the ball by increasing friction between the ball and the foot (for example, the article of footwear being worn on the foot). This may facilitate more precise and controlled movements during shooting and passing.
[0172] In some embodiments, the microtextured surface may contribute 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.
[0173] In some embodiments, the microtextured surface on the outer surface of the control element may provide additional reinforcement to the ankle portion of the article of footwear, as the textured material may offer increased structural integrity and support.
[0174] According to some embodiments of the present disclosure, the microtextured surface may comprise a plurality of protrusions.
[0175] The plurality of protrusions on the microtextured surface may provide additional friction and grip, thereby improving the user's ability to manipulate the ball with precision during play.
[0176] This interaction ensures that the control element can function more effectively by leveraging the increased surface area and texture provided by the protrusions.
[0177] In some embodiments, the protrusions may have any shape, including but not limited to a pillar shape. Further examples of shapes encompassed by the present disclosure may include spikes, knobs, ridges, tendrils, bumps, spines, tubercles, crests, and/or prongs. In some embodiments, 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.
[0178] In some embodiments, the arrangement and placement of the protrusions may be designed to enhance the performance of the article of footwear during activities such as shooting and passing a ball.
[0179] In some embodiments, 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. Providing bendable protrusions 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.
[0180] According to some embodiments of the present disclosure, one or more of the plurality of protrusions may comprise an aspect ratio defined by a height of a protrusion compared to a width of the protrusion of at least 1.1, at least 1.2, at least 1.3, at least 1.4, or at least 1.5; and/or of at most 10, at most 8, at most 6, at most 4, or at most 3.
[0181] In some embodiments, 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.
[0182] In some embodiments, the aspect ratio ranges may provide several advantages to the article of footwear. Firstly, by defining the aspect ratio to be within a certain range, the protrusions may be optimized for their intended function of assisting with shooting and/or passing a ball. The specified aspect ratios may ensure that the protrusions are neither too short and wide nor too tall and narrow, which could compromise their elastic properties and effectiveness.
[0183] In some embodiments, a higher aspect ratio within the defined range may ensure 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 may enhance the tactile feedback and control a player experiences when making contact with the ball, thereby improving performance in sports activities.
[0184] Additionally, the ranges for the aspect ratio provided herein may provide flexibility in design while ensuring that the protrusions remain within an optimal functional range. This may allow for variations in manufacturing processes and materials without compromising the performance characteristics of the article of footwear.
[0185] 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.
[0186] According to some embodiments of the present disclosure, one or more of the plurality of protrusions may comprise a width of at least 0.05 mm, at least 0.08 mm, or at least 0.1 mm; and/or of at most 1.0 mm, at most 0.7 mm, at most 0.5 mm, or at most 0.3 mm.
[0187] In some embodiments, the specified minimum width may ensure that the protrusions are robust enough to withstand repeated contact with the ball without breaking or deforming permanently.
[0188] Furthermore, providing protrusions comprising the widths provided herein may ensure 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.
[0189] In some embodiments, the protrusions, being within the defined width range, may be 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 may ensure that the protrusions are neither too thin to be fragile nor too thick to be inflexible.
[0190] Thus, the new features introduced by this embodiment may bring about a precise and optimized structural configuration of the protrusions, enhancing the overall functionality and performance of the article of footwear in assisting with ball control during sports activities.
[0191] According to some embodiments of the present disclosure, the control element may be arranged in an ankle portion of the article of footwear, such as 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.
[0192] When the control element is arranged in an ankle portion of the article of footwear, the control element may provide 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 may ensure that the control element directly contributes to the structural integrity of the ankle, thereby improving overall performance.
[0193] Furthermore, when the control element is arranged in a medial ankle portion of the article of footwear, the control element may offer additional benefits by focusing the reinforcement on the inner side of the ankle. This medial placement may 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 may provide enhanced support and control, which may lead to more precise and powerful ball handling.
[0194] Moreover, when the control element is positioned in the lateral ankle portion of the article of footwear, the control element may provide 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 may offer enhanced stability and support, thereby improving the user's balance. This can contribute to more effective and controlled movement.
[0195] Additionally, when the control element is arranged in an instep portion of the article of footwear, the control element may 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 may assist in improving the user's ability to strike the ball with greater force and precision.
[0196] 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.
[0197] According to some embodiments of the present disclosure, the inside shoe portion may comprise a further control element (for example, an additional control element such that the article of footwear may comprise two or more control elements), such as a further control element according to any preceding embodiments.
[0198] 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 herein.
[0199] In some embodiments, the further control element may be 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.
[0200] In some embodiments, 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 control elements on the outside shoe portion and the inside shoe portion, may ensure that the user has better grip, stability, and precision when handling the ball, whether for shooting, passing, or other soccer-related maneuvers.
[0201] According to some embodiments of the present disclosure, the control element may cover an area of at least 2%, at least 5%, at least 10%, at least 20%, at least 30%, or at least 40% of the article of footwear; and/or the control element may cover an area of at most 95%, at most 90%, at most 80%, at most 70%, at most 60%, or at most 50% of the article of footwear.
[0202] This feature introduces a specific quantitative measure of the control element's coverage, which may ensure that a minimum portion of the article of footwear is dedicated to the control element. Covering a certain area of the article of footwear with the control element may enhance the functional aspects of the control element by ensuring sufficient surface area to effectively assist with ball control and ankle reinforcement. This may aid 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.
[0203] Further, by setting an upper limit of the coverage area, a balance between the control element and other functional aspects of the article of footwear may be maintained. 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.
[0204] According to some embodiments of the present disclosure, the control element may comprise a height of at least 0.1 mm, at least 0.2 mm, at least 0.3 mm, or at least 0.4 mm; and/or of at most 8 mm, at most 6 mm, at most 4 mm, at most 3 mm, at most 2 mm, at most 1.5 mm, at most 1.2 mm, at most 1.0 mm, or at most 0.8 mm.
[0205] In some embodiments, the minimum height may ensure that the control element may be sufficiently prominent to provide tactile feedback and improve ball control.
[0206] In some embodiments, the maximum height of the control element may ensure that it does not become excessively bulky, which could interfere with the fit of the article of footwear within a shoe.
[0207] 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.
[0208] By carefully calibrating the height of the control element, the article of footwear may achieve 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.
[0209] According to some embodiments of the present disclosure, the control element may comprises a maximum dimension in a direction along the surface of the article of footwear of at least 2 mm, at least 5 mm, at least 10 mm, at least 20 mm, at least 40 mm, at least 60 mm, or at least 80 mm; and/or of at most 200 mm, at most 180 mm, at most 160 mm, at most 140 mm, or at most 120 mm.
[0210] In some embodiments, a control element with a maximum dimension of at least 2 mm may provide 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.
[0211] In some embodiments, a control element with a maximum dimension of at most 200 mm, 180 mm, 160 mm, 140 mm, and 120 mm may ensure 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 may maintain a balance between functionality and wearability, ensuring that the control element remains effective without compromising the overall design and comfort of the sock.
[0212] According to some embodiments of the present disclosure, the article of footwear may be a sock, such as a sock used for playing soccer.
[0213] In some embodiments, the sock may be close-fitting to the foot, flexible, and may comprise elastic material designed to conform snugly to the contours of the foot.
[0214] The technical properties shown or described above for the article of footwear, and the advantages and the improvements described above are likewise applicable to the sock, such as a sock used for playing soccer.
[0215]
[0216]
[0217] As described elsewhere herein, the article of footwear 100 disclosed herein aims to address the shortcomings of conventional articles of footwear by introducing the targeted control element 130 which may comprise one or more grip elements. In some embodiments, the control element 130 may be arranged in a medial ankle portion of the article of footwear 100. In some embodiments, the control element 130, for example the grip elements, may be applied using various materials, including liquid TPU, rubber, silicone, and/or micro-texture films, to create a 3D structure that may enhance grip and stability. Embodiments disclosed herein may consider the application of these materials in specific patterns, such as plain surfaces, dots, lines, or grid patterns, to maximize ball control and player proprioception.
[0218] By focusing on the portions of the article of footwear 100 that come into contact with the ball, embodiments disclosed herein may provide soccer players with improved ball reception and control, regardless of environmental conditions. The grip elements may also contribute to a perceived increase in ankle stability, further supporting the player's performance on the field.
[0219] In some embodiments, the outside shoe portion 110 may be at least partially exposed to an exterior (for example, the environment exterior of the shoe 50) when the article of footwear 100 is worn by a foot of a user and then received in a shoe 50.
[0220] In some embodiments, the control element 130 may be arranged on an outer surface of the outside shoe portion 110. In some embodiments, the control element 130 may be configured to increase a grip between the article of footwear 100 and a ball.

In some embodiments, the cross-section may be halfway of the height of the protrusion. The cross-sectional shapes may aid in improving provision of increased grip.
[0227] In some embodiments, one or more of the plurality of protrusions may comprise an aspect ratio defined by a height of a protrusion compared to a width of the protrusion of at least 1.1, at least 1.2, at least 1.3, at least 1.4, or at least 1.5, and/or of at most 10, at most 8, at most 6, at most 4, or at most 3.
[0228] In some embodiments, one or more of the plurality of protrusions may comprise a width of at least 0.05 mm, at least 0.08 mm, or at least 0.1 mm; and/or of at most 1.0 mm, at most 0.7 mm, at most 0.5 mm, or at most 0.3 mm.
[0229] As shown, the control element 130 may be arranged in an ankle portion 120 of the article of footwear 100. In some embodiments, the control element 130 may be arranged in a medial ankle portion of the article of footwear 100, and/or in an instep portion 125 of the article of footwear 100. In some embodiments, the control element 130 may be arranged in other portions of the article of footwear 100.
[0230] In some embodiments, the inside shoe portion 105 may comprise an additional control element (for example, another control element 130 such that the outside shoe portion may comprise a first control element 130 and the inside shoe portion 105 may comprise a second control element 130, as described elsewhere herein.

[0254] As described elsewhere herein, the control element 130 may be 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 herein 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 herein may mean that the player is striking with a rather fast foot movement to a goal. In particular, shooting may comprise strong striking shots, such as a power shot, for example a shot struck with maximum force, often used for long-range attempts. Another example may be a volley, for example a shot taken directly out of the air, generating significant power. Another example may be a half-volley, for example 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), for example 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), for example a shot taken from the penalty spot, often hit with great power to beat the goalkeeper.
[0255] Passing as referred to in here may comprise less powerful actions (like passing, dribbling, and first touches). In particular, passing may comprise dribbling, for example moving the ball with a series of controlled touches, often focusing on maneuverability rather than power. Another example may be a first touch, for example the initial touch used to control the ball, emphasizing precision and control. Another example may be a placed shot, for example a shot focused on accuracy, aiming to place the ball out of the goalkeeper's reach. Another example may be a chip shot, for example a delicate shot intended to loft the ball over the goalkeeper with minimal power. Another example may be a side-footed shot, for example a controlled and accurate shot using the side of the foot, typically less powerful.
