Description

Technical Field

[0001] The invention relates to an upper for a shoe, in particular a sports shoe. The upper comprises a ball contact area configured to assist in shooting a ball. The invention also relates to a shoe, in particular a running shoe, comprising such an upper attached to a sole. Background Art

[0002] Shoes, or footwear in general, are often described as a combination of an upper and a sole structure. Typically, the upper covers areas of the wearer's foot such as the instep, toes, medial side, lateral side, and heel, and provides an opening to allow the wearer to step into the shoe. The sole is connected to the upper so that during normal use of the shoe, the top side of the sole faces the foot and the bottom side of the sole contacts the ground.

[0003] The upper for a shoe generally serves multiple functions. The upper provides an enclosure for housing the foot, stabilizes the foot during movement, protects the foot from environmental influences, and, in the case of certain athletic shoes, provides a surface specifically adapted to the needs of an athlete. In particular, athletic footwear should be comfortable to wear, stabilize the foot, and attenuate stresses from bouncing between the foot and the ground during exercise. Footwear should support movement to avoid physical injury to the wearer.

[0004] Especially for the upper of the shoe used in sports activities such as soccer, rugby, football and other ball games, it is widely used and popular among the wearers. Such upper is becoming more and more important and has specific requirements in order to improve the performance of such sports activities.

[0005] As an example of such a requirement, it may be mentioned to enhance the grip of the vamp on the ball. Such enhanced grip has the possibility that the player can control the ball to a greater extent. In particular, the contact of the shoe with the ball is very important and the surface of the vamp plays an important role. One way to achieve an increased grip between the vamp and the ball is to provide a texture on the outer surface of the vamp. Another way to achieve an increased grip is to provide the vamp with protrusions. Both ways can increase the energy transfer from the vamp to the ball during a shot.

[0006] As is known, there are different types of shots. For example, there are arc passes, flat passes, striking shots, etc. For different types of shots, different settings are required on the upper of the shoe. However, for any type of shot, it is desirable to have proper rotation, because otherwise the ball will vibrate.

[0007] By way of example, the following prior art documents may be mentioned in the context of the present disclosure.

[0008] EP 3909459 A1 relates to an upper for a sports shoe, comprising a plurality of areas, the plurality of areas comprising: an inner foot area, an outer foot area, a toe area, an instep area, a heel area and a collar area, wherein the upper comprises at least one protrusion in at least four of the plurality of areas, and wherein the protrusion protrudes from an outer surface of the upper.

[0009] US2011 / 0258883A1 relates to a ball control portion for a footwear article. The ball control portion extends from one side of the footwear article to the lower side. The ball control portion includes a grid having a plurality of protrusions arranged in a grid. The plurality of protrusions include a plurality of groups of protrusions arranged in one or more of different orientations, different types of protrusions, and different heights.

[0010] EP 2891422 B1 relates to an article of footwear comprising a first set of gripping members comprising a first ball control portion and a second set of gripping members comprising a second ball control portion. The height of the first ball control portion varies along a first direction, and the first set of gripping members is substantially aligned with the second set of gripping members relative to a second direction.

[0011] In addition, the following prior arts can be cited as background knowledge.

[0012] WO 2010 / 086672 A1 relates to a sports shoe, wherein the upper of the sports shoe comprises a deformable protrusion in the forefoot area, the deformable protrusion comprising the form of a suction cup.

[0013] CN206390385U relates to a training sports shoe having a high elastic rubber outer layer, which is distributed on the outer surface in the form of small rubber cylindrical protrusions.

[0014] CN207269957 relates to a soccer shoe with high-speed ball control, wherein the upper is provided with protrusions comprising small round suction cups.

[0015] US 9693694 B2 relates to an article of footwear wherein the outsole may include lateral and medial arch portions for traction.

[0016] EP 1430801 A1 relates to an article of footwear, such as a soccer shoe, comprising a ball control area. The ball control area comprises a series of raised geometric protrusions of different sizes, which are arranged on the upper of the soccer shoe.

[0017] WO 2010 / 055276 A1 relates to a ball control component for sports shoes, wherein a plurality of diamond-shaped rubber parts are arranged on the upper surface of the ball control part.

[0018] Although the above-mentioned document claims an improvement over the known prior art, the solution proposed in said document still has some drawbacks when it comes to improving the grip of the vamp. For example, most of the prior art proposals involve rather rigid and hard geometries, which are not conducive to adequate deformation. Such rigid and / or hard geometries cause the ball in contact therewith to deform during the stroke. This limits the creation of grip between the vamp and the ball. The grip can then depend only on the material. Furthermore, the prior art solutions show rather rough transitions of motion when the vamp hits the ball.

[0019] When reviewing the prior art, one must conclude that there is still room for improvement.

[0020] Against this background, the object of the present invention is to provide an improved upper. The upper should provide improved means to assist in hitting a ball. In particular, a more advanced and / or dedicated spin should be provided for the ball. This should be possible in particular for attacking shots. Furthermore, an object is to provide a corresponding shoe comprising such an upper. Summary of the invention

[0021] The above objects are at least partly achieved by the subject matter of the independent claims. Preferred embodiments are the subject matter of the dependent claims, and further suitable aspects of the invention are described by the overall disclosure of the application.

[0022] In one aspect, the object is solved by an upper for a shoe, in particular a sports shoe, comprising: a) a ball contact area comprising a plurality of protrusions; b) wherein each of the plurality of protrusions has an elongated shape having a longitudinal axis, a side portion facing the sole and a side portion facing the instep; and c) wherein the ball contact area is configured to assist in striking a ball, in that each of the plurality of protrusions is capable of elastically bending, such that each protrusion is configured to bend substantially in a direction perpendicular to the longitudinal axis when in contact with a ball, and such that each of the plurality of protrusions is configured to bend such that the side portion facing the instep contacts an outer surface of the upper or an adjacent protrusion of the plurality of protrusions.

[0023] In this way, the vamp helps to improve the assisting of hitting the ball, which is particularly useful for ball sports like football. In particular, the ball contact area provides an enhanced means for contacting the ball, which ensures that sufficient grip is available. In addition, a smoother transition for hitting the ball, such as shooting, is provided. Due to the elastically bendable protrusion, a brushing effect can be established. Without wishing to be bound by theory, this brushing effect means that multiple brushes (e.g., protrusions) can contact the ball and affect the path of travel of the ball after leaving the vamp. In addition, the elastically bendable protrusion has an additional benefit, namely increasing the contact time of the ball on the vamp. The inventors have found that this is particularly advantageous compared to most suggestions in the prior art, according to which a fairly rigid protrusion is provided. The latter does not allow the desired elastic bending described herein, and therefore cannot provide the advantages described herein.

[0024] In addition, the curvature of the protrusion has the advantage of increasing the surface area of ​​the shoe upper that can contact the ball. This helps to improve the shot. It should be understood that the amount of curvature can depend on the force of the shot. For example, the curvature can increase as the force of the shot increases.

[0025] To further highlight the advancement of the present disclosure, it may be helpful to analyze the trajectory of the ball along the upper. The term "trajectory of travel" may refer to the relative motion between the upper and the ball. In one example, the ball may first contact the upper in a first contact portion, and may move along the ball contact area toward the second contact portion where the ball finally contacts the upper. From the second contact portion, the ball may accelerate away from the upper. The first contact portion may be arranged closer to the edge of the sole. The second contact portion may be arranged closer to the instep portion. This movement of the ball may be more or less dominant, depending on the type of shot. For example, in curling shots, it may be more prominent, and in arc shots, the foot is "followed through" to produce the ball rotation. It has been found that this rotation is also desirable for straight shots, such as attack shots to the goal. In particular, shots without rotation will tremble, and rotation provides an additional benefit of keeping the ball on a substantially straight path to, for example, the goal. Note that there are many different types of shots, such as arc passes or flat passes. However, the present disclosure may be primarily directed to attack shots. Such an attacking stroke may be understood as a stroke towards a goal etc. As described in more detail elsewhere herein, the inventors have found that directing the longitudinal axis of the protrusion substantially perpendicular to the trajectory of travel provides additional benefits for assisting the stroke.

[0026] Without wishing to be bound by theory, it is believed that the rotation of the ball has a beneficial effect on its path of travel through the Magnus effect. The Magnus effect can be understood as a phenomenon in fluid dynamics that describes the force acting on a rotating object (e.g., a ball) moving through a fluid (e.g., air). When a rotating ball moves in the air, it may therefore be subject to a force perpendicular to the direction of its path of travel. The Magnus effect is commonly observed in sports activities; however, this is also known from aerodynamics, industrial processes, and / or vehicle performance. When a ball is kicked or thrown with rotation, the air moving around the ball may be deflected in different directions due to the rotation. This deflection may produce a pressure difference between two opposite sides of the ball. This may result in a net force perpendicular to the direction of its path of travel (i.e., airflow). As a result, the ball may deviate from a straight path. This may have advantages because an attacking shot may be less predictable for the goalkeeper of the opposing team. This in turn may increase the chances of scoring and / or achieving a desired result. Alternatively or additionally, it may allow a shot around or over the opposing team's free kick wall in a soccer match. The direction and magnitude of the Magnus force may depend on various factors, including but not limited to the ball's speed, spin rate, density of the air, and / or roughness of the ball's surface.

[0027] The attack stroke referred to here requires different settings of the protrusions on the upper to take into account the different travel trajectories of the ball (for example, compared to a flat pass). The attack stroke is generally a stronger stroke than other types of strokes (for example, just a pass stroke). Although there may be variations between athletes, those skilled in the art are still able to distinguish attack strokes from other types of strokes, such as a pass stroke. Attack strokes typically occur during play, and the medial and top sides of the foot and the bone portion of the first metatarsal joint are primarily used to contact the ball. In particular, the foot can be tilted toward the outside of the foot, and the ball can travel in a rearward direction toward the outside of the foot along the surface when impacted.

[0028] The ball contact area may be understood as an area, portion, surface portion, etc. that can come into contact with a ball, etc. In particular, the ball contact area may be an area that comes into contact with the ball during a stroke. It will be appreciated that due to the deformation of the ball when the ball is struck, the ball contact area may be larger than the area covered if the ball merely rests on the upper without striking the ball.

[0029] Each of the plurality of protrusions has an elongated shape, which means that along one axis of the shape may have a dimension that is greater than one dimension, preferably two dimensions, along the remaining one axis (preferably the remaining two axes), the remaining axes being substantially perpendicular to the one axis. It should be understood that when describing dimensions herein, manufacturing tolerances must generally be taken into account. Although not always explicitly expressed (e.g., by using the term "substantially"), it should be understood that the components, elements, units, shapes described herein include such manufacturing tolerances. Therefore, the dimensions described herein may vary slightly.

[0030] The side portion facing the sole and the side portion facing the instep can be understood as portions on two different sides of the projection. As an example, the portions can be on two opposite sides of a plane along the longitudinal axis. In addition, the side portion facing the sole and the side portion facing the instep can extend substantially parallel to the longitudinal axis, as described later. In addition, the portions can alternatively or additionally be substantially perpendicular to the outer surface of the upper. As will be appreciated by those skilled in the art, the side portion facing the sole may not be the side of the projection facing the outer surface of the upper and / or in contact with the outer surface of the upper (e.g., the projection can be attached to the outer surface of the upper at this location).

[0031] The side portion facing the sole may point toward the front portion of the upper, such as toward the toe portion. For example, when a ball contacts the protrusion in a conventional attack shot, the ball may first contact the side portion facing the sole. This results in a bending of the protrusion. Furthermore, when the protrusion bends, the side portion facing the sole may at least partially point upward.

[0032] When the protrusion is not bent, the side portion facing the instep may point to the instep portion and / or more generally to the rear portion of the upper. It is understood that when the ball contacts the protrusion in a conventional attack shot, the protrusion may be bent. Furthermore, when the protrusion is bent, the side portion facing the instep may at least partially point downward. For example, when the protrusion is bent, the side portion facing the instep may point to the upper and / or sole of the shoe.

[0033] The side portion facing the sole and the side portion facing the instep can be free parts, for example, parts free to the environment. To illustrate this in the example, the side portion facing the sole and the side portion facing the instep can be touched by the user, etc.

[0034] A shot may include any possible action in which the player positions the shoe so that the upper contacts the ball. As an example, a shot may include attacking, dribbling, passing, etc. However, as discussed in more detail herein, a shot preferably means that the player is attacking, e.g., hitting the ball with a fairly fast foot movement.

[0035] Each of the plurality of protrusions is elastically bendable. This means that, for example, the protrusion can bend when subjected to an external force, such as the force provided by the ball. In addition, the bending is elastic, which means that the bending is basically carried out within the elastic deformation range of the material of the protrusion. Within this elastic deformation range, the stress and strain of the material can behave according to a linear relationship. This elastic (and linear) relationship of the material can also be called Young's modulus. In contrast, plastic bending means that some deformation cannot be recovered.

[0036] Each protrusion is configured to bend substantially in a direction perpendicular to the longitudinal axis when in contact with the ball. This means that the bending is performed to a greater or significant degree perpendicular to the longitudinal axis. The protrusions may still bend in different directions. The term "substantially" may emphasize that manufacturing tolerances may be included in order to determine the perpendicular direction.

[0037] It has been found that such curvature in the vertical direction is particularly useful in view of the trajectory of the ball during a shot. This allows the vertical curvature to be established at substantially any portion of the upper along which the ball travels, which helps to provide improved grip, increased contact area and increased contact time along the overall trajectory of travel. Thus, each time a protrusion is curved, the benefits of one protrusion are accumulated along the trajectory of travel on the upper during a shot.

[0038] Each of the plurality of protrusions is configured to be bent so that the side portion facing the instep contacts the outer surface of the upper or an adjacent protrusion in the plurality of protrusions. The term "contact" can be understood as making the side portion facing the instep at least partially contact the outer surface of the upper or an adjacent protrusion in the plurality of protrusions. It is impossible that all the side portions facing the instep actually contact the outer surface of the upper or an adjacent protrusion in the plurality of protrusions in all cases. On the contrary, a part thereof, that is, the side portion of the protrusion facing the instep (which can be the top portion of the side portion facing the instep) can usually contact the outer surface of the upper or an adjacent protrusion in the plurality of protrusions. In one example, a plurality of protrusions can be spaced far apart so that even if the protrusion is bent to a considerable degree, it is impossible to contact an adjacent protrusion.

[0039] The upper described herein can be particularly used in combination with sports shoes, such as soccer shoes. However, it should be noted that the upper can be used with any kind of footwear, including but not limited to soccer shoes, hiking boots, sports shoes, basketball shoes, rugby shoes, baseball shoes, golf shoes, tennis shoes, cross-training shoes. In addition, the upper can be used in combination with shoes for any type of sports activities. The term sports activities should be understood to include at least one or more and / or any combination of the following non-exhaustive list: aerobics, exercise, running, hiking, climbing, group fitness classes, walking, cycling, yoga, football, tennis, rugby, basketball, exercise, volleyball, gymnastics, weightlifting, cross-training, baseball, softball, rugby, hockey, wrestling, squash, track and field (e.g., sprinting, long jump, high jump), cross-country skiing.

[0040] The protrusions that provide the additional benefits described herein may additionally or alternatively be used in clothing and / or equipment used in sporting activities. That is, the protrusions need not be limited to the example of being used in the upper of a shoe. It is feasible to transfer the concept of a ball contact area to any type of sporting activity where it is necessary to provide spin to the ball, such as (table tennis rackets), etc.

[0041] However, it has been found that the advantages of the protrusions described herein are particularly pronounced when applied to the upper of a shoe, such as a shoe used during sporting activities, in particular football.

[0042] In a preferred embodiment of the upper as described herein, each protrusion of the plurality of protrusions has a substantially triangular cross-section.

[0043] A cross section is understood to be a cross section along a plane whose normal is parallel to the longitudinal axis. In one example, the triangular cross section of this embodiment may mean that the bottom of the protrusion is larger than the top. Alternatively, the top may be larger than the bottom, although other examples may be preferred.

[0044] This has the advantage that the protrusion is supported to a greater extent. In addition, this cross section improves bending since the tip portion can be more flexible.

[0045] In a preferred embodiment of the upper as described herein, each protrusion of the plurality of protrusions has a top edge and a bottom edge that are substantially parallel to each other along the longitudinal axis.

[0046] The top edge may be understood as the free edge, i.e. the edge facing the environment. The bottom edge may be opposite to said top edge and may be attached to the upper, or formed integrally with the upper. This has the benefit of improving bending. For example, when a ball hits a protrusion, it may easily bend around the bottom edge, thereby forming a pivot axis.

[0047] Each of the plurality of protrusions may include additional edges in the top and / or bottom of the protrusion to allow for more advanced configurations and / or shapes. This may increase the variety of usage scenarios of the upper, for example, by providing protrusions of specific shapes for certain portions of the upper.

[0048] In a preferred embodiment of the upper as described herein, each protrusion of the plurality of protrusions has a substantially quadrilateral longitudinal cross-section, preferably a trapezoidal longitudinal cross-section.

[0049] A longitudinal section may be understood as an intersection plane along the longitudinal axis of the elongated protrusion. In other words, a longitudinal section may be understood as a plane whose normal is perpendicular to the longitudinal axis of the elongated protrusion.

[0050] A quadrilateral longitudinal cross section means that four corners can be identified. A quadrilateral longitudinal cross section further improves the bend and supports the beneficial effects associated therewith (e.g. increased ball contact area and increased contact time). A trapezoidal longitudinal cross section has the added benefit that one edge can be shorter than the opposite edge. The shorter edge can be the top edge. This has the advantage that no sharp corners are provided which would adversely affect providing sufficient spin to the ball.

[0051] In a preferred embodiment of an upper as described herein, the longitudinal axis forms an acute angle α with the heel-to-toe axis of the upper, the acute angle being at least 45°, preferably at least 50°, preferably at least 60°, preferably at least 65°, preferably at least 70°, preferably at least 75°, preferably at least 80°, preferably at least 85° in the toe portion of the upper; and / or, at most 45°, preferably at most 40°, preferably at most 35°, preferably at most 30°, preferably at most 25°, preferably at most 20°, preferably at most 15°, in the medial midfoot portion of the upper.

[0052] In this embodiment, the acute angles of the protrusions in the toe portion of the upper are greater than the acute angles of the protrusions in the medial midfoot portion of the upper. This has the advantage that the orientation of the protrusions is adjusted to take into account the trajectory of the ball. In particular, it can therefore be the case that before the ball is struck, the ball travels substantially perpendicularly to the longitudinal axis of each protrusion. This improves the assistance for striking the ball.

[0053] In particular, such orientation relative to the ball can result in greater deformation of the protrusion, which can increase the restoring force of the protrusion, which acts in the direction of the desired ball rotation. In addition, the contact time can be increased. The contact area can also be increased. It is understood that the contact area and / or the amount of bending can increase with the force acting on the ball (e.g., the impact force).

[0054] As will be appreciated, the acute angle measures less than 90 degrees.The heel-to-toe axis of the upper corresponds to a substantially straight line connecting a heel portion and a toe portion of the upper.

[0055] In a preferred embodiment of the upper as described herein, a first protrusion of the plurality of protrusions is arranged in a toe portion of the upper, and a second protrusion is arranged further rearward relative to the first protrusion, wherein an acute angle of the first protrusion is greater than an acute angle of the second protrusion, preferably at least 10° greater, preferably at least 15° greater, preferably at least 20° greater, preferably at least 25° greater, preferably at least 30° greater, preferably at least 35° greater, preferably at least 40° greater.

[0056] From the above described embodiment, various advantages of this embodiment can be derived. In particular, it is found that a greater deformation of the protrusion can be achieved thereby. Moreover, the restoring force of the protrusion acts in the opposite direction of the trajectory of the ball. This promotes the desired ball rotation.

[0057] In one example, as the second protrusion is disposed further rearward relative to the first protrusion, the acute angle of the second protrusion continuously decreases.

[0058] In a preferred embodiment of the upper as described herein, each protrusion of the plurality of protrusions has a shape of at least one of a ridge, a slit, a sheet or a fin.

[0059] Such shapes are generally understood to be protrusions or extended structures. They can be thin and flat, etc. They can provide some function in modifying the fluid dynamics near them and / or enhancing stability. When the upper is used most of the time, such as when no ball is struck, these shapes may be less intrusive. Thus, they promote a natural feel on the wearer's foot. Such shapes can be easily manufactured and are helpful for ball striking.

[0060] In preferred embodiments of the upper as described herein, at least two protrusions of the plurality of protrusions differ in at least one of their shape, size and / or orientation.

[0061] Depending on the portion of the upper, a specific shape, size, and / or orientation may be desired. Different materials may also be desired. As described elsewhere herein, the orientation may vary along the ball contact area. In addition, the length of the protrusions may vary along the ball contact area. This may provide dedicated functionality for certain portions of the ball contact area. The length of the protrusions may also depend on the number of protrusions in one area.

[0062] In a preferred embodiment of the upper described herein, each protrusion of the plurality of protrusions has a chamfered edge at one end, preferably at both ends, along the longitudinal axis.

[0063] A beveled edge may refer to an edge or surface that is angled or slanted, rather than perpendicular or flush with adjacent edges and / or adjacent surfaces. A beveled edge is characterized by an inclined or slanted cut that creates an inclined plane along the edge.

[0064] This has the advantage of preventing protruding sharp corners and / or pointed portions. These could otherwise lead to undesired effects on the ball. As an example, when the upper is used for passing the ball or the like at a relatively low speed of movement, the ball could be adversely affected when hitting the ball with such sharp corners and / or pointed portions.

[0065] Furthermore, the chamfered edge provides reduced mechanical stress. In particular, stress peaks often occur near sharp corners and / or pointed portions. This can be avoided by this embodiment.

[0066] One or both ends may be understood as an edge forming one or both opposite ends, which edge may be free to the environment.

[0067] In a preferred embodiment of an upper as described herein, a travel track is defined on the upper, wherein a longitudinal axis of each protrusion is oriented substantially perpendicular to the travel track.

[0068] Preferably, the travel trajectory includes one or more travel directions, wherein a first travel direction is arranged in a toe portion of the upper and extends from the toe portion, in particular from the tip of the toe toward an instep portion or a middle midfoot portion of the upper, wherein a second travel direction is preferably arranged in an inner foot portion of the upper and extends from the lower inner foot midfoot portion of the upper toward an instep portion or a middle midfoot portion of the upper, wherein one or more intermediate travel directions are preferably arranged between the first travel direction and the second travel direction, and wherein the orientation of one or more intermediate travel directions varies between an orientation corresponding to one of the first travel directions and an orientation corresponding to one of the second travel directions, wherein the variation is preferably continuous and / or monotonous from the toe portion of the upper to the inner foot portion of the upper.

[0069] This has the advantage that the projection is bent substantially in the direction defining the travel path.

[0070] It should be appreciated that the trajectory of travel may depend to some extent on personal preference, the type of shot, and / or the intensity of the shot.

[0071] As described elsewhere herein, this trajectory is applicable to the common attack shot usually performed during a soccer match. In addition, for example, in the case of a so-called "top spin shot", the trajectory of the ball may be opposite, as described elsewhere herein.

[0072] In a preferred embodiment of the upper as described herein, a plurality of protrusions protrude from an outer surface of the upper.

[0073] This can be understood as making the protrusion extend significantly from the outer surface of the upper. This means that in one example, the protrusion cannot be understood as an element placed in a recessed portion of the outer surface of the upper. Instead, it should be recognized that the protrusion substantially starts from the outer surface of the upper and extends into the free environment. This helps to assist in hitting the ball as described herein.

[0074] In a preferred embodiment of the upper as described herein, the height of each of the multiple protrusions in the protruding direction is at least 0.5 mm, preferably at least 1 mm, preferably at least 1.5 mm, preferably at least 2 mm, most preferably at least 2.5 mm, and / or, at most 5 mm, preferably at most 4.5 mm, preferably at most 4 mm, preferably at most 3.5 mm, preferably at most 3 mm, most preferably at most 2.5 mm.

[0075] The protrusions should not have too great a height, as this would adversely affect the natural feel of the upper on the wearer's foot. Furthermore, this could result in a considerable weight. The protrusions should additionally or alternatively not have a considerable short height, as this could impair the desired benefits in assisting the ball.

[0076] Applicants have succeeded in obtaining an optimal compromise between these conflicting requirements for the protrusion height as described herein.

[0077] As described herein, the protrusion direction is the direction in which the protrusion extends from the outer surface of the upper. The protrusion direction can be defined when the protrusion is not bent. The protrusion direction can be a direction substantially corresponding to the normal line of the outer surface of the upper.

[0078] In a preferred embodiment of the upper as described herein, each of the multiple protrusions has a width substantially perpendicular to the protrusion direction and the longitudinal axis, which is: at least 0.1 mm, preferably at least 0.2 mm, preferably at least 0.3 mm, preferably at least 0.4 mm, preferably at least 0.5 mm, most preferably at least 0.6 mm; and / or, at most 1.5 mm, preferably at most 1.25 mm, preferably at most 1.0 mm, preferably at most 0.9 mm, preferably at most 0.8 mm, preferably at most 0.7 mm, most preferably at most 0.6 mm.

[0079] With the widths specified herein, an optimal balance can be achieved between sufficient bendability, material savings, and / or a less intrusive natural feel (desirable low widths) and sufficient support and / or mechanical integrity (desirable large widths).

[0080] It should be understood that the width may vary along the height of the protrusion. For example, the width at the bottom of the protrusion may be greater than the width at the top of the protrusion (this may also be reversed in some cases).

[0081] The width at the bottom of the protrusion may be about 1 mm to 1.5 mm, preferably about 1.1 mm to 1.4 mm, preferably about 1.2 mm to 1.3 mm. At about half the height of the protrusion, the width may be about 0.5 mm to 0.8 mm, preferably about 0.6 mm to 0.7 mm. The width at the top of the protrusion may be smaller than the width at about half the height of the protrusion.

[0082] In a preferred embodiment of the upper as described herein, the length of each of the multiple protrusions substantially along the longitudinal axis is: at least 2 mm, preferably at least 4 mm, preferably at least 6 mm, preferably at least 8 mm, preferably at least 10 mm, most preferably at least 15 mm; and / or, at most 40 mm, preferably at most 30 mm, preferably at most 25 mm, preferably at most 20 mm, most preferably at most 15 mm.

[0083] The protrusions with a greater length are advantageous for improving the assist in striking the ball. The protrusions with a shorter length have the advantage that the hardness of the upper and / or the risk of damage is reduced.

[0084] With the suggested lengths specified herein, Applicants have found the best compromise between these conflicting requirements.

[0085] In preferred embodiments of the upper described herein, the length of the top edge along the longitudinal axis is at most 100%, preferably at most 90%, preferably at most 80%, preferably at most 70%, preferably at most 60%, preferably at most 50%, and / or at least 50%, preferably at least 60%, preferably at least 70%, preferably at least 80%, preferably at least 90%, preferably at least 100% of the length of the bottom edge along the longitudinal axis.

[0086] The length of the top edge is preferably less than the length of the bottom edge. This improves bending and facilitates assisting the shot. However, the present disclosure also encompasses embodiments in which the top edge is larger than the bottom edge.

[0087] In a preferred embodiment of the shoe upper described herein, the distance between two adjacent protrusions is at least 0.5 times, preferably at least 0.75 times, more preferably at least 1 times, the height of one protrusion.

[0088] This has the advantage that there is enough space between two adjacent protrusions to allow one or both of them to bend as described herein.

[0089] The protrusion used as a reference when determining the distance may be the front protrusion. The front protrusion may be a protrusion disposed closer to the toe portion of the upper as viewed along the heel-to-toe axis of the upper. Alternatively, the protrusion used as a reference when determining the distance may be the rear protrusion, i.e., a protrusion on the opposite side of the front protrusion.

[0090] In a preferred embodiment of the upper as described herein, each of the plurality of protrusions is constructed to be bent at a bending angle of at least 5°, preferably at least 10°, preferably at least 15°, preferably at least 20°, preferably at least 25°, preferably at least 30°, preferably at least 35°, preferably at least 40°, preferably at least 45°.

[0091] This facilitates that each protrusion can be bent to a relatively large amount. This provides an improved grip, as well as increased contact time with the ball. As described herein, when the protrusion is bent, the side portion facing the instep can contact the outer surface of the upper or an adjacent protrusion of the plurality of protrusions. In this manner, it will be appreciated that increasing the bend angle supports such contact. Prior art solutions are typically quite hard and / or rigid, which does not allow for such bending.

[0092] The bending angle may be understood as an acute angle of a line protruding from the base to the top of each protrusion when bent relative to a line along the protruding direction of the protrusion when not bent.

[0093] In a preferred embodiment of the upper described herein, each protrusion is spaced apart from the sole of the shoe on the medial side of the upper by at least 5 mm, preferably at least 6 mm, preferably at least 7 mm, preferably at least 8 mm, preferably at least 10 mm, preferably at least 12 mm, preferably at least 16 mm, preferably at least 20 mm.

[0094] According to this embodiment, the protrusions for attacking shots can be placed better, for example, compared to arc shots, etc. In particular, attacking shots are characterized in that the ball may not contact such a portion near the sole in the inner foot portion of the upper. Therefore, it is advantageous that the protrusions are spaced apart from them to a sufficient extent and / or are not present in such a portion. In particular, more delicate ball control movements, such as dribbling or flat passes, are not impaired thereby. In addition, since the protrusions are only placed at the desired locations, the number of protrusions and the weight generated by them is reduced.

[0095] In a preferred embodiment of the upper as described herein, no protrusions are provided in a lower medial portion of the upper, which is substantially directly adjacent to at least one of the sole of the shoe, the lateral portion of the upper and / or the heel of the upper.

[0096] Moreover, this embodiment facilitates better placement of the protrusions for attacking shots compared to passing shots. As described elsewhere and in particular in the previous embodiments, advantageously, the protrusions are not present in such portions. Thus, more delicate ball handling movements, such as dribbling or passing, are not impaired, since such ball handling movements typically require that the portion of the upper proximal to the lower medial side of the sole, for example, be primarily in contact with the ball. Furthermore, this embodiment reduces the number of protrusions required and the weight that is generated thereby.

[0097] In a preferred embodiment of the upper as described herein, the ball contact area is at least partially disposed in at least one of the big toe portion, the big toe joint portion, the first metatarsal joint portion, the first metatarsal bone portion, the medial midfoot portion of the upper, and / or the middle midfoot portion. In one example, one or more of the plurality of protrusions are at least partially disposed in at least one of the big toe portion, the big toe joint portion, the first metatarsal joint portion, the first metatarsal bone portion, the medial midfoot portion of the upper, and / or the middle midfoot portion.

[0098] This embodiment facilitates the placement of ball contact areas and / or protrusions in strategically located, highly relevant portions of the upper. This is particularly the case for attacking shots.

[0099] The medial midfoot portion of the upper may include bones such as the cuneiform and the navicular. The middle midfoot portion may be the dorsal portion, i.e., the portion between the medial and lateral portions of the foot. When there are no laces, a ball contact area including a protrusion may be present in the middle midfoot portion.

[0100] In preferred embodiments of an upper as described herein, no protrusions are provided in a lower medial midfoot portion of the upper, or flat or inflexible protrusions are provided in a lower medial midfoot portion of the upper.

[0101] The advantages of this embodiment can also be derived from the above-described embodiment. In addition, the flat or inflexible protrusion can correspond to a protrusion of a different type than the protrusion described elsewhere herein (which is bendable). In particular, the flat or inflexible protrusion can be a printed protrusion, etc.

[0102] The term "inflexible" may describe an object and / or material that is not easily bent, flexed, and / or deformed under ordinary conditions. An inflexible protrusion may exhibit a strong resistance to bending. An inflexible protrusion may exhibit an inability to be bent.

[0103] In a preferred embodiment of the upper as described herein, at least two protrusions from the plurality of protrusions are connected by a base element on the outer surface of the upper.

[0104] This has the advantage that the protrusions are provided with sufficient support, which additionally facilitates the positioning of the protrusions and their attachment. The base element may be realized from a harder material than the protrusions. Alternatively, the base element may be realized from a material substantially the same or similar to the protrusions.

[0105] In a preferred embodiment of the upper as described herein, the base element passes substantially through a middle portion of each protrusion.

[0106] The middle portion of each protrusion may be understood as the middle portion relative to its length along its longitudinal axis. This improves the protrusions being held together at the portion that may be subjected to the greatest external forces. Thus, the base element further supports the protrusions being securely attached. This also improves the durability of the upper and its lifespan. In turn, the upper may be more cost-effective.

[0107] As will be appreciated, the base element may additionally encompass a greater portion of the protrusion on the outer surface of the upper, i.e. it may encompass, for example, at least 20%, at least 50% or at least 80% of its length along its longitudinal axis. However, it is preferred that the base element is rather thin relative to its extension along the outer surface of the upper. Thus, it may preferably comprise at most 30% or at most 20% of the length of the protrusion along its longitudinal axis.

[0108] In preferred embodiments of the upper as described herein, the base element has a thickness of: at most 1.5 mm, preferably at most 1 mm, preferably at most 0.8 mm; and / or, at least 0.2 mm, preferably at least 0.4 mm, most preferably at least 0.5 mm.

[0109] This generally has the advantage of avoiding a bulky and / or stiff feeling to the upper, thereby providing a more natural feel on the wearer's foot.

[0110] The thickness should not be too large, as this would adversely affect the natural feel of the upper on the wearer's foot. In addition, a large thickness may result in considerable weight. Additionally or alternatively, the thickness should not be too small, as this may compromise the desired benefits in supporting the protrusions and providing a secure attachment.

[0111] Applicants have succeeded in obtaining an optimum compromise between these conflicting requirements with the thicknesses specified herein.

[0112] The thickness may be measured substantially parallel to the protrusion direction of the protrusion. In other words, the thickness may be measured substantially parallel to the normal to the outer surface of the upper.

[0113] In a preferred embodiment of the upper as described herein, at least two protrusions are formed integrally with the base element and are arranged in a first group in the ball contact area.

[0114] The at least two protrusions formed integrally with the base element have the advantage of improving its manufacture. Furthermore, the mechanical integrity is enhanced and thereby the life of the upper is improved. In particular, there may be fewer parts that are subject to stress peaks etc. This may be due in particular to the absence of any means for connection, such as adhesives etc.

[0115] In a preferred embodiment of the upper as described herein, the ball contact area comprises at least two further protrusions formed integrally with the further base element and arranged in a second group, wherein the first group and the second group are spaced apart by a distance greater than any two protrusions of the first group or the second group, preferably by a distance between adjacent protrusions.

[0116] Similar advantages mentioned in the above-mentioned embodiment also apply to this embodiment.

[0117] Furthermore, this embodiment has the advantage that the ball contact area can be increased and / or the ball contact area comprises more protrusions. A variety of different designs can be created thereby: for example, the second group can be arranged at any desired part of the upper, for example on the toe / vamp / instep area, which facilitates that the desired properties that facilitate the ball strike can be achieved.

[0118] In various examples, the first group and / or the second group comprises two, three, four, five or six protrusions, preferably the first group comprises six protrusions. When the second group is arranged further back as seen from the toe portion, the second group preferably comprises fewer protrusions than the first group. For example, when the second group constitutes the rearmost group, the group may comprise two or three protrusions.

[0119] In a preferred embodiment of the upper as described herein, the ball contact area includes recesses arranged between the first group and the second group.

[0120] The recesses may have the advantage that water and / or dirt may be guided therethrough, which improves that the portion of the upper in contact with the ball remains substantially dry and / or clean. Thereby, grip is improved and the spin imparted to the ball is improved.

[0121] This recess may be particularly advantageous in wet weather conditions where moisture may adversely affect friction because water may rest on the outer surface of the upper.

[0122] The recess may be implemented in various ways, including but not limited to recesses in the shape of grooves, pipes, etc. The recess may be continuous. The recess may additionally or alternatively include portions with varying depths in order to provide a variety of different configurations for improving the properties of the upper in certain portions thereof.

[0123] In preferred embodiments of the upper as described herein, the protrusions of the first and / or second group are arranged substantially parallel to each other along their longitudinal axes, wherein the protrusions of the first and / or second group are preferably substantially equidistantly spaced from each other.

[0124] In a preferred embodiment of the upper as described herein, each protrusion of the plurality of protrusions comprises a material comprising at least one of rubber, elastomer, cast polyurethane (CPU) and / or silicon.

[0125] These materials are readily available, cost effective and widely accepted in the field of uppers and / or shoes. In addition, softer or harder materials can be used depending on the degree of flexibility required. This allows fine-tuning the response of the upper to the ball. In addition, the choice of material for the protrusions can depend on the remaining material of the upper, for example, the lower material of the upper. This has advantages in terms of attachment. In addition, the use of rubber and / or CPU can fine-tune and customize the grip and assistance of the shot.

[0126] Rubber includes high energy transfer, which is preferably in the ball contact area described herein. In the case where better adhesion than rubber materials is required, CPU and / or silicon materials can be used. In particular, CPU and / or silicon materials are particularly suitable when bonding with fabrics.

[0127] Typically, the material has the advantage of high energy transfer, which promotes the bending of the protrusions resulting in high restoring forces. Therefore, the energy stored in the bent protrusions can be returned to the ball to provide the desired spin.

[0128] The protrusions may be manufactured by any kind of manufacturing methods including, but not limited to, overmolding, additive manufacturing methods (eg, 3D printing methods), and / or composite processing methods.

[0129] In a preferred embodiment of the upper described herein, each protrusion of the plurality of protrusions comprises a material having a hardness ranging from 30-60 Shore A, more preferably 35-55 Shore A, even more preferably 40-50 Shore A, and most preferably 40-45 Shore A.

[0130] This Shore A hardness provides advantages in the bending of the protrusions and the corresponding restoring force once the protrusions are bent. This in turn can provide additional benefits in providing the desired spin to the ball.

[0131] Furthermore, the Shore A hardness ensures a smoother transition for attacking shots (e.g., compared to the relatively hard geometries known in the prior art). This has been found to be particularly advantageous for attacking shots (e.g., compared to other shots such as passing shots).

[0132] Shore hardness can be a measure of a material's resistance to indentation. Different types of Shore hardness scales are suitable for measuring the hardness of different materials, such as (e.g., soft rubber, hard plastic, and super-soft gel). Generally, the higher the value on the scale, the harder the material. For example, the difference between the Shore A and Shore D scales is that Shore A can be specified for measuring flexible rubber, while Shore D can be specified for harder, rigid materials. The ranges can overlap at certain levels, such as at higher levels.

[0133] In a preferred embodiment of the upper as described herein, the upper further comprises a tongue configured to be folded so as to at least partially overlap a lace of the upper.

[0134] An advantage of the tongue is that it at least partially covers the laces of the upper. Thus, the tongue can improve ball contact. In particular, the tongue can provide a smooth surface for the ball. Thus, impairment of ball contact through the laces can be reduced and / or significantly mitigated.

[0135] In one example, the tongue may be disposed in the instep portion and / or the middle midfoot portion.

[0136] In a preferred embodiment of the upper as described herein, the ball contact area is a first ball contact area and the tongue comprises a second ball contact area comprising a plurality of protrusions according to any of the embodiments described herein.

[0137] This has the advantage that the beneficial properties provided by the plurality of protrusions are extended to a larger area of ​​the upper. In particular, the portion of the foot where the tongue is provided may be the portion along which the ball travels during the trajectory of travel. Therefore, it has been found that providing a second ball contact area on the tongue improves the provision of spin to the ball.

[0138] In a preferred embodiment of the upper as described herein, the second ball contact area is configured to substantially abut the first ball contact area when the tongue is folded.

[0139] This can be understood in such a way that the second ball contact area continuously provides an increased total ball contact area without any gaps in between etc. Therefore, a smooth and continuous total ball contact area can be provided.

[0140] Adjacent may be understood as the border of the second ball contact area being directly adjacent to the border of the first ball contact area. It cannot be excluded that the first ball contact area and the second ball contact area are spaced apart to a certain extent. This may depend on the exact position of the tongue and / or the degree of folding of the tongue, as will be understood by a person skilled in the art.

[0141] As an alternative to the upper including the tongue, the upper may be a laceless upper. Such a laceless upper has the potential to save time for athletes when wearing shoes including such an upper. In addition, cleaning the shoes becomes easier. Furthermore, the laceless upper avoids the possibility that the laces may become tangled and cause accidents or injuries. Furthermore, the laceless upper also avoids the problem of the laces suddenly becoming loose during exercise such as playing football.

[0142] In an embodiment according to which the upper is a laceless upper, the ball contact area is at least partially arranged in the middle midfoot portion, ie the portion where the laces are usually arranged for an upper with laces. This increases the ball contact area.

[0143] In a preferred embodiment of the upper as described herein, the side portion facing the sole and the side portion facing the instep extend substantially parallel to the longitudinal axis.

[0144] This may have benefits in terms of manufacturing. It is still possible that the side portion facing the sole and the side portion facing the instep do not extend completely parallel to the longitudinal axis. For example, as described elsewhere, the cross-section may have a triangular shape. In this regard, the term "substantially" may emphasize that for parallel alignment, manufacturing tolerances may be included.

[0145] In a preferred embodiment of the upper as described herein, the side portion facing the sole and the side portion facing the instep are on opposite sides of a plane that is substantially perpendicular to the outer surface of the upper along the longitudinal axis.

[0146] In a preferred embodiment of the upper as described herein, one or more protrusions are disposed in a big toe portion, a big toe joint portion, a middle midfoot portion, and / or a lateral foot portion of the upper, each of the one or more protrusions being spaced apart by a first average distance. In addition, one or more protrusions are disposed in a medial midfoot portion and / or a first metatarsal joint portion of the upper, each of the one or more protrusions being spaced apart by a second average distance. The first average distance may be greater than the second average distance.

[0147] An advantage of the described embodiments having protrusions at different intervals in various portions of the upper is that it can provide customized structural support and comfort for the wearer's foot. This can include, for example, targeted support and flexibility. For example, by providing protrusions at different intervals in specific areas of the upper, the shoe can provide more support where needed, such as around the big toe and joints, while allowing greater flexibility in other areas such as the middle midfoot or first metatarsal joint. This can help accommodate natural foot movements and provide stability. In addition, the varying distances between the protrusions can help the upper conform more closely to the unique shape of the wearer's foot, potentially enhancing fit and reducing slippage within the shoe.

[0148] In a preferred embodiment of the upper as described herein, one or more protrusions are disposed in a big toe portion, a big toe joint portion, a middle midfoot portion, and / or a lateral foot portion of the upper, each of the one or more protrusions having a first average density of protrusions. In addition, one or more protrusions are disposed in a medial midfoot portion and / or a first metatarsal joint portion of the upper, each of the one or more protrusions having a second average density of protrusions. The first average density may be lower than the second average density.

[0149] Similar advantages as described in the aforementioned embodiment can be applied.

[0150] On the other hand, these objects are solved by a shoe, in particular a sports shoe, comprising: an upper according to any of the embodiments described herein; and a sole attached to the upper.

[0151] It goes without saying that the technical properties, advantages and improvements over the prior art shown or described for the shoe upper also apply to shoes, in particular sports shoes. BRIEF DESCRIPTION OF THE DRAWINGS

[0175] BRIEF DESCRIPTION OF THE DRAWINGS

[0176] Figures 1 to 3 An exemplary upper 101 ( FIG. 101 ) for a shoe 100, in particular a sports shoe, according to an embodiment of the present invention is shown in three different perspective views. Figure 1 , Figure 2 , Figure 3 ).

[0177] The upper 101 includes a ball contact area 150 including a plurality of protrusions 151 (not all protrusions are shown for simplicity). Each protrusion 151 of the plurality of protrusions 151 has an elongated shape having a longitudinal axis LA (eg, Figure 2 ), the side portion 151a facing the sole (as shown in Figure 4 ) and the side portion 151b facing the instep (as best shown in FIG. Figure 4 ). Ball contact area 150 is configured to assist in striking ball 80 (e.g. Figure 4), because each protrusion 151 of the plurality of protrusions 151 is elastically bendable, each protrusion 151 is configured to bend substantially in a direction perpendicular to the longitudinal axis LA when in contact with the ball 80, and each protrusion 151 of the plurality of protrusions 151 is configured to bend so that the side portion 151b facing the instep contacts the outer surface of the upper 101 or an adjacent protrusion 151 of the plurality of protrusions 151.

[0178] As from Figure 1 As can be seen in the figure, each protrusion 151 of the plurality of protrusions 151 may have the shape of at least one of a ridge, a cleft, a thin sheet, or a fin. For example, the protrusion 151 may have a major axis, such as a length, which is significantly greater than a minor axis, such as a width. In addition, each protrusion 151 of the plurality of protrusions 151 may have a chamfered edge on one end, preferably on both ends, along the longitudinal axis LA. The chamfered edge may be formed by removing material from the edge at a specific angle and / or by cutting an inclined surface along the edge. The angle of the chamfered surface may vary depending on the intended purpose and / or aesthetic considerations.

[0179] like Figure 2 As shown, a heel-to-toe axis HT is shown. In addition, one longitudinal axis LA represents an exemplary protrusion 151 among the plurality of protrusions 151 of the toe portion 105 (the corresponding longitudinal axis LA has a suffix 105). The longitudinal axis LA_105 forms an acute angle α of at least 45°, preferably at least 50°, preferably at least 65°, preferably at least 85° with the heel-to-toe axis HT of the upper 101 in the toe portion 105 of the upper. In addition, one longitudinal axis LA represents an exemplary protrusion 151 among the plurality of protrusions 151 of the upper medial midfoot portion 112 of the upper 101 (the corresponding longitudinal axis LA has a suffix 112). In addition, the longitudinal axis LA_112 forms an acute angle α of at most 45°, preferably at most 35°, preferably at most 25°, preferably at most 15° with the heel-to-toe axis HT in the upper medial midfoot portion 112 of the upper 101.

[0180] In addition, as Figure 2 In the example shown, a first protrusion 151 of the plurality of protrusions 151 is disposed in the toe portion 105 of the upper 101, and a second protrusion 151 is disposed further rearward relative to the first protrusion 151 (e.g., in the medial midfoot portion 112 of the upper). The acute angle α of the first protrusion 151 (in the toe portion 105) may be greater than the acute angle α of the second protrusion 151 (in the medial midfoot portion 112 of the upper), preferably at least 10° greater, preferably at least 20° greater, preferably at least 30° greater, preferably at least 40° greater.

[0181] Furthermore, each protrusion 151 of the plurality of protrusions 151 has a substantially quadrilateral longitudinal cross section, preferably a trapezoidal longitudinal cross section. The longitudinal cross section is a cross section along the longitudinal axis LA of the elongated protrusion 151 .

[0182] If available from Figures 1 to 3 It is further understood that at least two protrusions 151 of the plurality of protrusions 151 differ in at least one of their shape, size and / or orientation. Each protrusion 151 of the plurality of protrusions 151 may protrude from the outer surface of the upper 101. Therefore, they may extend into a free environment.

[0183] The ball contact area 150 may be at least partially disposed in at least one of the big toe portion, the big toe joint portion, the first metatarsal joint portion, the first metatarsal bone portion, the medial midfoot portion 112 , and / or the middle midfoot portion 120 .

[0184] Ball contact area 150 may include one or more of the following: a middle and / or medial toe portion, a medial metatarsal portion (which may be proximal to sole 102), a middle and medial instep portion (which may be similar to middle midfoot portion 120 as described elsewhere herein), and a front heel portion. The term "middle" may refer to the portion between the lateral side of the foot and the medial side of the foot. The term "middle" may be referred to as the dorsal side.

[0185] Figure 4 Schematic diagrams showing a plurality of protrusions 151 in a normal state and in a bent state according to an embodiment of the present disclosure.

[0186] Each protrusion 151 of the plurality of protrusions has an elongated shape with a longitudinal axis pointing toward Figure 4 In addition, each protrusion 151 has a side portion 151a facing the sole (on one side of the longitudinal axis) and a side portion 151b facing the instep (on the other side of the longitudinal axis). Each protrusion 151 of the plurality of protrusions 151 has a substantially triangular cross section. The cross section is along a plane whose normal is parallel to the longitudinal axis, i.e., pointing to Figure 4 In addition, each protrusion 151 of the plurality of protrusions 151 has a top edge at the top 151d and a bottom edge at the bottom 151c. Both edges are oriented along the longitudinal axis, i.e., pointing to the Figure 4 The bottom 151c may be in the image plane of the image plane and are substantially parallel to each other. Due to the triangular cross-section, the bottom 151c may have two edges.

[0187] like Figure 4As shown, each protrusion 151 of the plurality of protrusions 151 can be configured to be bent at a bending angle β of at least 5°, preferably at least 10°, preferably at least 15°, preferably at least 20°, preferably at least 25°, preferably at least 30°, preferably at least 35°, preferably at least 40°, preferably at least 45°. As can be seen, by the bending angle, when the protrusion 151 is bent, the side portion 151a facing the sole can be at least partially directed upward. In addition, when the protrusion 151 is bent, the side portion 151b facing the instep can be directed toward the upper and / or sole of the shoe 100.

[0188] Figure 4 Also shown is a height h substantially in the protruding direction of each protrusion 151. As described elsewhere herein, the height may be at least 0.5 mm, preferably at least 1 mm, preferably at least 1.5 mm, preferably at least 2 mm, most preferably at least 2.5 mm, and / or, at most 5 mm, preferably at most 4.5 mm, preferably at most 4 mm, preferably at most 3.5 mm, preferably at most 3 mm, most preferably at most 2.5 mm. In addition, Figure 4 The width w of each protrusion 151 of the plurality of protrusions 151 is shown, which is perpendicular to the protrusion direction and perpendicular to the longitudinal axis LA. As described elsewhere herein, the width w can be at least 0.1 mm, preferably at least 0.2 mm, preferably at least 0.3 mm, preferably at least 0.4 mm, preferably at least 0.5 mm, and most preferably at least 0.6 mm; and / or, at most 1.5 mm, preferably at most 1.25 mm, preferably at most 1.0 mm, preferably at most 0.9 mm, preferably at most 0.8 mm, preferably at most 0.7 mm, and most preferably at most 0.6 mm. The length of each protrusion 151 of the plurality of protrusions 151 is substantially along the longitudinal axis (e.g. Figure 2 105, or along the longitudinal axis LA_112 of the medial midfoot portion 112 of the upper). Note that the protrusions 151 can have a maximum length so that there can be no protrusions 151 that extend continuously across the ball contact area 150. This has the advantage that recesses 155, 155', 155", such as grooves, can be provided between the protrusions 151, such as along the medial to lateral direction or the lateral to medial direction, as described elsewhere herein.

[0189] The groove may have different cross-sectional shapes, such as rectangular, trapezoidal, circular and / or irregular shapes and / or combinations thereof. The cross-sectional shape may depend on the width, depth and / or angle of the groove's sides. The width of a groove may refer to the distance between its two substantially parallel sides. It may be measured substantially perpendicular to the direction of flow, such as a flow of water (e.g., due to rain). The depth of a groove may refer to the vertical distance between the bottom of the groove and the top of the groove. It can usually be measured from the bottom of the groove to a reference point. A groove may also be described by its slope or gradient. This slope or gradient may describe a change in height along its length. It may represent a measure of the steepness of the rise or fall of the groove. In the case where rainwater is directed from one point of the upper to another fairly quickly, a change in slope or gradient may be advantageous. The slope is usually expressed as a ratio or percentage. One or more recesses 155, 155', 155" described herein may alternatively or additionally be implemented by a passage, a conduit, a tube, a duct, a canal, a corridor, a groove, etc.

[0190] Figures 5 to 7 Three different perspective views are used to illustrate an exemplary upper 201 ( FIG. 201 ) for a shoe 200, in particular a sports shoe, according to another embodiment of the present invention. Figure 5 , Figure 6 , Figure 7 ).

[0191] This embodiment corresponds to the remaining embodiments described herein and emphasizes the main differences, but also presents common features. The reference numerals correspond to the remaining embodiments with the hundreds digit increased by one, ie, upper 201 corresponds to upper 101 in the remaining embodiments described herein.

[0192] This embodiment is a laceless upper 201, which saves time when putting on a shoe 200 including such an upper 201. Such a laceless upper 201 avoids the possibility that the laces may get tangled and cause accidents or injuries.

[0193] In addition, the ball's trajectory TT is shown in this embodiment, however, this also applies to any other embodiments described herein and is not limited to Figures 5 to 7 For the sake of clarity, the travel trajectory TT is omitted in the remaining embodiments.

[0194] The travel trajectory TT may include one or more travel directions TD1, TDi, TD2 (eg Figure 6 and Figure 7201). The first travel direction TD1 is shown, which is substantially arranged in the toe portion of the upper 201. The first travel direction TD1 may extend from the toe portion, in particular from the tip of the toe toward the instep portion of the upper 201. The second travel direction TD2 is substantially arranged in the medial portion 110 of the upper 201. The second travel direction TD2 may extend from the medial midfoot portion below the upper 201 toward the instep portion. Figure 6 and 7 It can also be seen in FIG. 1 that a plurality of intermediate travel directions TDi are shown, which are substantially arranged in the portion between the first travel direction TD1 and the second travel direction TD2. The intermediate travel directions TDi smoothly transition from an orientation substantially corresponding to the first travel direction TD1 to an orientation substantially corresponding to the second travel direction TD2. As will be appreciated, although in Figure 6 Two intermediate directions of travel TDi are indicated in Figure 6 One intermediate direction of travel TDi is indicated in , but there are multiple intermediate directions of travel.

[0195] As mentioned herein, the travel trajectory TT may include one or more of the travel directions TD1, TDi, TD2. As an example, when the first contact portion is in the toe portion of the upper 201, the ball may first travel along the travel direction TD1, then travel along the travel direction TD2, and end at the second contact portion near the instep portion of the upper 201.

[0196] As will be appreciated, there are multiple exemplary travel trajectories TT. For example, the athlete may strike the ball slightly differently than in the previous example. For example, the first contact portion may be proximal to the metatarsal. In such an example, Figure 6 and 7 The travel direction TD1 indicated in may not be included by the travel trajectory TT, ie during this shot.

[0197] The travel trajectory TT includes one or more of the depicted travel directions TD1, TDi, TD2. This can be interpreted, without wishing to be bound by theory, as the ball can deform during a shot. Therefore, a relatively large surface of the upper 201 can be in contact during a ball impact, as described elsewhere herein.

[0198] The longitudinal axis LA of each protrusion 151 is oriented substantially perpendicular to the travel directions TD1, TDi, TD2 in the corresponding portion of the upper 201. Since the travel path TT includes one or more of these travel directions TD1, TDi, TD2, the longitudinal axis LA of each protrusion 151 may also be oriented substantially perpendicular to the travel path TT. The travel path TT may point to the top and rear of the upper 201. It may start from multiple points along the edge of the sole 202 of the shoe 200. It may extend toward the middle midfoot portion 120.

[0199] In addition to the above analysis of the ball's trajectory TT, the ball's trajectory TT may be reversed, for example, in the case of a so-called "topspin shot". For such a shot, the first ball contact portion may be backward and / or toward the shoe opening. The second ball contact portion may be toward the toe portion 105. For such a "topspin shot", topspin is required and / or desired. During this type of shot, the foot hits the ball substantially in a center and moves through in an upward direction of the ball. As will be appreciated by those skilled in the art, for these types of shots, the ball's trajectory TT may be reversed from the trajectory TT described elsewhere herein.

[0200] As will be appreciated, a plurality of protrusions 151 may be disposed on upper 201 such that at least one of protrusions 151 may be oriented substantially perpendicular to a corresponding type of shot, such as a curve shot, a straight shot, or the like.

[0201] like Figure 7 As best shown in FIG. 1 and applicable to all embodiments described herein, each protrusion 151 can be spaced at least 5 mm, preferably at least 8 mm, preferably at least 12 mm, preferably at least 16 mm, preferably at least 20 mm from the sole 202 of the shoe 200 in the medial side portion 120 of the upper 201. In addition, in the upper 201, the lateral side portion 115 (such as the upper 201) of the shoe 200 is substantially directly adjacent to the sole 202 of the shoe 200. Figure 3 The protrusion 151 may be absent from the medial side portion 111 of at least one of the upper 201 and / or the heel portion 125 (best shown in FIG. 1 ).

[0202] In particular, if Figure 1 and Figure 7 As shown in the figure, it is possible that no protrusion 151 is provided in the lower medial midfoot portion 111 of the upper 101, or a flat or inflexible protrusion may be provided in the lower medial midfoot portion 111 of the upper 101. These flat or inflexible protrusions may be manufactured in various ways, including but not limited to 3D printing, etc.

[0203] like Figure 7 As indicated exemplarily in FIG. 1 , the shoes 100, 200 may be provided with spikes 180 (only two are shown for simplicity), which may also be referred to as anti-slip spikes. These may be used to provide traction for athletes on the ground, particularly soft ground, such as grass or the like. In the field of ball sports, such as soccer or football (e.g., American football), rugby, etc., the use of spikes is known. In some examples, the spikes may be integrally formed with the sole 202 of the shoe 200. The spikes 180 may be at least partially injection molded onto the base material. In various examples, the prefabricated spike tips may be placed in a mold and overmolded with the base material. The base material may include a portion of the sole 202. In various examples, the spikes 180 may include TPU. The integrally formed or injection molded spikes 180 have the advantage that no screws are required and / or the spikes 180 do not need to be replaced. However, interchangeable spikes 180 or screw-on spikes 180 may also be applied.

[0204] Figure 8 A detailed perspective view shows Figure 6 As described elsewhere herein, at least two protrusions 151 of the plurality of protrusions 151 may be connected by a base element 156 on the outer surface of the upper 201. The at least two protrusions 151 may be integrally formed with the base element 156. The at least two protrusions 151 may be disposed in a first group 160 of the ball contact area 150. In this figure, exemplarily six protrusions 151 are connected by the base element 156, and the six protrusions 151 form a group 160 disposed in the toe portion 105 of the upper 201.

[0205] The thickness of the base element 160 may be at most 1.5 mm, preferably at most 1 mm, preferably at most 0.8 mm in thickness (in the protrusion direction PT of the protrusion 151, e.g. Figure 4 and / or at least 0.2 mm, preferably at least 0.4 mm, most preferably at least 0.5 mm.

[0206] In various examples, the first 156 and / or second 156' base element covers an area on the upper 201 that corresponds to the sum of the areas of each base of the protrusions 151 on the base elements 156, 156'. Preferably, the first 156 and / or second 156' base element is at least 1.05 times larger, preferably at least 1.1 times larger, most preferably at least 1.15 times larger than the sum of the areas of each base of one or more protrusions 151 on the base elements 156, 156'; and / or at most 1.3 times larger, preferably at most 1.25 times larger, preferably at most 1.2 times larger, most preferably at most 1.15 times larger than the sum of the areas of each base of one or more protrusions 151 on the base elements 156, 156'.

[0207] In various examples, the profile of the base elements 156, 156' may correspond to the profile of the bottom of each of the protrusions 151, but slightly protrude outward. In one example, there may be a connection between each profile. Alternatively, the space between each protrusion 151 of the same set 160, 160' may be completely covered by the base elements 156, 156'.

[0208] In addition, if Figure 8 As shown, the base member 160 passes substantially through a middle portion of each protrusion 151 .

[0209] In addition, the ball contact area 150 may include at least two further protrusions 151 formed integrally with the further base element 156' and arranged in a second group 160' (note that the protrusions 151 of the second group 160' are not shown for clarity only). The second group 160' is also arranged in the toe portion 105 of the upper 201. However, as described elsewhere herein, the second group 160' may also be arranged further rearward (e.g., as shown in FIG. 1 ). Figure 5 ). It can be seen that the first and second groups 160, 160' are spaced apart larger than any two, preferably adjacent, protrusions 151 of the first or second groups 160, 160'. This allows for the formation of recesses (eg, grooves) as described below to allow water and waste to flow through.

[0210] In addition, the ball contact area 150 includes a recess 155 disposed between the first group 160 and the second group 160'. Another recess 155' is shown in this figure, which is disposed near the first group 160 and / or the second group 160' and toward the rear end thereof. The recesses 155, 155' can take the shape of grooves or the like as described elsewhere herein.

[0211] As from Figure 8 As can be understood in the above, the protrusions 151 of the first group 160 and / or the second group 160' are arranged substantially parallel to each other along their longitudinal axes LA. In addition, the protrusions 151 of the first group 160 and / or the second group 160' are preferably spaced substantially equidistant from each other. In addition, Figure 8 It is shown that the distance between two adjacent protrusions 151 may be at least 0.5 times the height of one of the protrusions 151 , preferably the front protrusion 151 , preferably at least 0.75 times, more preferably at least 1 times.

[0212] It is emphasized that the description of the base elements 156, 156', the first group 160 and / or the second group 160' can be equally applicable to any other embodiment described herein. In addition, the number and arrangement of the groups 160, 160' are far from being limited to Figure 8 For example, Figure 5Four groups 160, 160', 160", 160'" are shown, each of which can be provided with a corresponding base element. The first group 160 is arranged in the toe portion 105 having six protrusions 151. The second group 160" is arranged in such a portion, which covers a part of the toe portion 105 and a part of the medial midfoot portion 112 of the upper having six protrusions 151. The third group 160" is arranged in the medial midfoot portion 112 of the upper having two protrusions 151. The fourth group 160'" is also arranged in the toe portion 105 having six protrusions 151. In addition, Figure 5 With Figure 8 The two recesses 155 are indicated in a similar manner.

[0213] As another example of the setting of a group, Figure 1 Two groups 160, 160' are shown, each group can be provided with a corresponding base element. Note that the indication of the group is not limited to these examples, for example, a person skilled in the art will Figure 1 It is concluded that the upper 101 may include eight groups, three of which are in the toe portion 105, and the remaining portion of which is in the rear portion relative to the toe portion 105. Exemplarily, Figure 1 Indicates three recesses 155, 155', 155" disposed between the groups 160, 160' (not all groups are indicated for the sake of brevity). Although Figure 1 Although not explicitly indicated in the embodiment, in this embodiment, at least two protrusions 151 of the plurality of protrusions 151 may also be connected by a base element 156 on the outer surface of the upper 101. The at least two protrusions 151 may be integrally formed with the base element 156.

[0214] Fig. 9 and 10 An exemplary upper 301 for a shoe 300 , particularly a sports shoe, is shown according to another embodiment of the present invention. Fig.10 Shown in different perspectives and different transparency modes Fig. 9 Embodiment of the invention.

[0215] This embodiment corresponds to the rest of the embodiments described herein and emphasizes the main differences, but also presents common features.

[0216] Here, upper 301 includes tongue 390 that is configured to be folded to at least partially overlap the lace of upper 301 .

[0217] The ball contact area 150 described elsewhere herein is a first ball contact area 150, and the tongue 390 includes a second ball contact area 350 that includes a plurality of protrusions 151 according to any of the embodiments described herein. As seen, the second ball contact area 350 can be configured to substantially abut the first ball contact area 150 when the tongue 390 is folded.

[0218] It should be noted that one or more protrusions 151 may be disposed in the big toe portion, the big toe joint portion, the middle midfoot portion, and / or the lateral foot portion of the upper, with each of the one or more protrusions 151 spaced apart by a first average distance. Additionally, one or more protrusions 151 may be disposed in the medial midfoot portion and / or the first metatarsal joint portion of the upper, with each of the one or more protrusions 151 spaced apart by a second average distance. The first average distance may be greater than the second average distance.

[0219] This can have the advantage that closer spacing of the protrusions in certain areas can provide a cushioning effect, which can reduce pressure points and increase comfort during activities involving a lot of foot movement or impact. In addition, the strategic placement of the protrusions can reinforce high stress areas of the shoe, potentially improving the durability and life of the product. The placement of the protrusions can also be designed to produce a visually appealing pattern, which can enhance the marketability of the shoe. Depending on the design, the spacing between the protrusions can also affect the breathability of the upper, with larger spacing allowing more air circulation. By adjusting the spacing of the protrusions, the design can affect how weight and pressure are distributed on the foot, which can help reduce fatigue and improve the wearer's gait.

[0220] It should be noted that one or more protrusions 151 may be disposed in the big toe portion, the big toe joint portion, the middle midfoot portion, and / or the lateral foot portion of the upper, each of the one or more protrusions 151 having a first average density of protrusions. Additionally, one or more protrusions 151 are disposed in the medial midfoot portion and / or the first metatarsal joint portion of the upper, each of the one or more protrusions 151 having a second average density of protrusions 151. The first average density may be lower than the second average density.

[0221] In any one or more embodiments of the upper described herein, the instep facing side portion of each protrusion covers at least 20%, preferably at least 30%, preferably at least 40%, preferably at least 50%, preferably at least 60%, preferably at least 70%, preferably at least 80%, preferably at least 90% of the instep facing side of each protrusion. In other words, each of the plurality of protrusions is configured to bend so that at least 20%, preferably at least 30%, preferably at least 40%, preferably at least 50%, preferably at least 60%, preferably at least 70%, preferably at least 80%, preferably at least 90% of the instep facing side of each protrusion contacts the outer surface of the upper or an adjacent protrusion of the plurality of protrusions.

[0222] In any one or more embodiments of the upper described herein, the first group is arranged in a toe portion of the upper, wherein the longitudinal axis LA of one or more protrusions of the first group is oriented substantially from the medial portion of the upper to the lateral portion of the upper, preferably wherein the longitudinal axis LA forms an acute angle of at least 45°, preferably at least 50°, preferably at least 55°, preferably at least 60°, preferably at least 65°, preferably at least 70°, preferably at least 75°, preferably at least 80°, preferably at least 85° with the heel-to-toe axis of the upper.

[0223] In any one or more of the embodiments of the upper described herein, the second group is disposed in a medial midfoot portion of the upper, for example near the first metatarsal bone, and / or near medial midfoot bones such as the cuneiform and the navicular bone, and / or in a middle midfoot portion, wherein a longitudinal axis of one or more protrusions of the second group is oriented from the medial foot portion to the toe portion of the upper, preferably wherein the longitudinal axis forms an acute angle of at most 45°, preferably at most 40°, preferably at most 35°, preferably at most 30°, preferably at most 25°, preferably at most 20°, preferably at most 15° with a heel-to-toe axis of the upper - in the medial midfoot portion of the upper of the upper.

[0224] In any one or more embodiments of the upper described herein, the protrusions 151 may be implemented by curved protrusions 151 and / or by varying the angles of adjacent protrusions 151 , which may be substantially aligned along their longitudinal axis LA.

[0225] In any one or more embodiments of the upper described herein, each protrusion 151 of the plurality of protrusions 151 comprises a material comprising at least one of rubber, elastomer, cast polyurethane CPU, and / or silicon. In addition, in all of the above embodiments, each protrusion 151 of the plurality of protrusions 151 comprises a material having a hardness in the range of 30-60 Shore A, more preferably 35-55 Shore A, even more preferably 40-50 Shore A, and most preferably 40-45 Shore A.

[0226] As will be appreciated by those skilled in the art, the upper and lower limits of the hardness value range may be combined with one another.

[0227] In any one or more embodiments of the upper described herein, reference to "first", "second", etc. corresponds only to the naming of elements, components, groups, etc. Such naming should not be interpreted as limiting, but is only used for the purpose of illustrating the present disclosure.

[0228] It should be noted that, as will be understood by those skilled in the art, any one or more of the embodiments and / or examples described herein may be combined with other aspects as described herein, and the details of the embodiments and / or examples may also be omitted. The scope of protection is determined by the claims and is not limited by the embodiments and / or examples disclosed in the above drawings.
