Description

[Technical Field]

[0001] The present invention relates to a shoe, particularly a sports shoe, that controls the positioning of a user's foot during exercise. In particular, the present invention relates to a planar (optionally containing microstructures) flat control portion located on the lateral and / or medial, posterior and / or anterior surfaces of the shoe, configured to contact the surface when performing a specific exercise. [Background technology]

[0002] One form of exercise that has grown in popularity in recent years is bodyweight exercise. Bodyweight exercises use the body's weight as resistance and do not require any additional equipment or weights. These exercises are versatile, require minimal space, and can be done almost anywhere. Bodyweight training is an effective way to tone the body, improve flexibility, and enhance overall health. For example, high-intensity interval training (HIIT) is a form of exercise that focuses on short, intense bursts of movement followed by short rest periods. The goal is to maximize activity and intensity during exercise, which often leads to more efficient and effective results. These exercises are often performed in gyms.

[0003] For example, when working out at the gym, the most common sports shoes are running shoes or lifting shoes. Running shoes are designed to provide comfort, support, and performance to runners. These shoes are designed for outdoor training and focus on optimizing dynamic movement and foot strike. However, stability in prone positions during quasi-static movements, bodyweight exercises, or weightlifting exercises is not prioritized. Specifically, running shoes have rocker soles that provide improved cushioning, but this does not support the exerciser's stability and balance during certain quasi-static exercises. Both dynamic and quasi-static strength and HIIT movements typically require a body posture that is significantly different from standing or running. Therefore, one disadvantage of such running shoes is that they are not optimized to stabilize the exerciser during typical gym exercises, such as HIIT or bodyweight exercises.

[0004] Weightlifting shoes have flat soles with little or no cushioning, which provide a stable base for lifting large weights, especially during exercises such as squats and deadlifts. While the lack of cushioning helps maintain direct contact with the ground, it does not support the athlete's foot posture when using such shoes for dynamic movements. Similarly, weightlifting shoes are not optimized to support foot positioning and movement during high-speed, dynamic movements such as jumping and sprinting.

[0005] Typically, when performing HIIT exercises, the exerciser quickly becomes fatigued because the HIIT exercises are very intense and strenuous. When an exerciser becomes fatigued, the ability to maintain proper form is significantly reduced, which may impair the quality of the exercise. One of the disadvantages of soles and footwear known in the art is that they do not adequately support the exerciser's feet and posture when the exerciser becomes fatigued. As a result, the exerciser adopts an incorrect posture during exercise, which in the long term may lead to injury or harm to the exerciser's health.

[0006] The document EP 2226763 A1 discloses a sole system for use primarily, but not exclusively, in the sports shoe and sneaker segments. The system has a spring system arranged between a foot-side sole and a ground-side sole. Spikes and traction elements are attached to the ground-side sole. Interchangeable flexible elements provide roll, pivot, twist, and rotation processes that are input into the locomotor system of the shoe wearer.

[0007] Document EP 0 324 471 A1 discloses the construction of a shoe, in particular a sports shoe such as a running shoe, which comprises a sole that adapts to the natural shape of the foot, in particular the lateral part, and which has a constant thickness in cross section at the front.

[0008] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an improved shoe to overcome the problems of the prior art discussed above. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] European Patent Application Publication No. 2226763 [Patent Document 2] European Patent Application Publication No. 0324471 Summary of the Invention

[0010] The problems outlined above are addressed and solved by aspects of the present invention.

[0011] According to a first aspect of the present invention, there is provided a shoe, in particular a sports shoe, comprising a sole, an upper and one or more planar (i.e. flat) control portions configured to contact a surface when performing a particular exercise in order to control the positioning of a user's foot during exercise.

[0012] The "planar control portion" of a shoe can be understood to be, for example, a portion of the shoe that is located on the lateral side, and / or medial side, rearward side, and / or forward side of the shoe. The planar control portion does not have a significant curvature, does not conform to the shape of the foot, and provides a flat, even surface. It may be microstructured, but still provides a flat, even surface. The planar control portion may, for example, be coupled or connected to the sole of the shoe, or the planar control portion may be molded from the same material as the sole or otherwise integrated into the sole. It is also conceivable that the planar control portion may be connected to or integrated into the shoe upper or other portion of the shoe.

[0013] "Contact" can be understood as the direct physical connection that occurs when performing a particular movement.

[0014] When referring to a "planar" control portion, this can generally refer to a smooth, flat, even, and / or sheet-like characteristic, e.g., relating to any surface that does not have significant curvature. For example, a planar control portion can form part of the side of a shoe, but does not have significant curvature.

[0015] "Exercise" can be understood as physical activity undertaken to maintain or improve health or physical condition. It involves repetitive, planned movements, often with the goal of improving strength, endurance, flexibility, or overall well-being. For example, exercise can be a workout, training, physical exercise, planned fitness, conditioning, exercise routine, or physical training. In particular, exercise is preferably dynamic and / or quasi-static movements, more preferably bodyweight exercise such as high-intensity interval training (HIIT) exercise, especially dynamic or quasi-static movements, such as push-ups, side planks, central planks, backward planks, handstand push-ups, skater jumps, forward lunges, Bulgarian lunges, and / or burpees.

[0016] A "surface" can be any surface that is in contact with when performing an exercise. A "surface" refers to, for example, a natural or artificial surface such as a terrain or surface, the ground, gravel, or a structure such as a floor, a wall, or a ceiling. In particular, a "surface" relates to the floor on which the exercise is performed. This floor is, for example, the ground itself when performing push-ups, or a wall when performing handstand push-ups. Furthermore, a "surface" can be understood as any surface of an object. This object is, for example, used during exercise. For example, in this context, a "surface" is the surface of equipment, for example, sports equipment used in a gym.

[0017] When referring to "performing a specific exercise," this generally relates to performing a sports exercise. For example, this relates to the process of a user performing a specific sports posture during a workout. These exercises may be dynamic or quasi-static movements, such as bodyweight exercises, particularly push-ups, side planks, central planks, backward planks, handstand push-ups, skater jumps, forward lunges, Bulgarian lunges, and / or burpees.

[0018] "Foot positioning control" refers to the properties of a shoe that allow for guidance and adjustment of foot position during exercise. For example, when a user is doing a push-up, the shoe controls foot positioning with planar control areas that help the user find the correct posture during this exercise.

[0019] Generally, when the shoe of the present invention is used on a flat surface, such as flat ground, when standing or walking, the planar control portion of the shoe does not engage the surface. Only when the shoe rolls or tilts on one of its edges does the planar control portion contact and engage the surface.

[0020] The present invention is based on the provision of a shoe having one or more planar control portions on the lateral and / or medial surfaces that assist the user in performing, for example, bodyweight exercises while maintaining proper form during dynamic and quasi-static movements.

[0021] By using the shoe of the present invention, the foot positioning is actively guided to the proper position by the planar control portion. In this way, an improved shoe is provided for, for example, performing bodyweight exercises. In particular, the shoe guides the user to the proper foot position, thereby supporting the user's foot positioning during exercise. The shoe of the present invention provides one or more flat or (micro-)textured surfaces that provide the user with a stable posture within a certain rotational range that physically guides the movement. In this way, the shoe allows for assisted guidance of foot placement during quasi-static, stability-critical movements.

[0022] Compared to existing sports shoes, the present invention provides improved foot stability and at the same time helps athletes maintain their posture through improved balance. Furthermore, the user, e.g., the athlete, can maintain the quality and consistency of their movements even when fatigued during exercise. Therefore, the present invention further enables improved endurance and athletic performance for the user, and at the same time, can help prevent long-term injuries due to improper execution of exercise.

[0023] The shoe may include a sole and an upper, the sole may be an outsole and / or a midsole, and one or more planar control portions may be located on the sole or the shoe upper or both.

[0024] The planarity control portion may be part of the sole of the shoe of the present invention. For example, in this context, the planarity control portion may be made of the same material as that used for the sole. The same is also conceivable when the planarity control portion is part of the shoe upper, i.e., the planarity control portion in this context may be made of the same material as that used for the shoe upper. It is also conceivable that the planarity control portion is part of both the sole and the shoe upper. The sole may be located on the outermost surface of the shoe for greater stiffness or responsiveness. The planarity control portion is part of the shoe and can be located in any part of the shoe, such as the shoe upper and / or the sole.

[0025] In various embodiments, the normal of at least one of the one or more planar control portions may be substantially perpendicular to the normal of the shoe's ground contact surface.

[0026] The ground contact surface of the shoe refers to the lower layer of the shoe that comes into direct contact with the surface under normal conditions. It should be noted that the ground contact surface should not be understood to include surrounding surfaces, such as the outer edges of the shoe and sole, but only refers to the lower layer of the bottom of the shoe that comes into contact with the surface when the user is standing. For example, the planar control portion may be located at the heel portion of the shoe at a right angle to the ground contact surface.

[0027] In various embodiments, at least one of the one or more planar control portions is at least 2 cm 2 , preferably at least 2.5 cm 2 , more preferably at least 3 cm 2 , most preferably at least 4 cm 2 In some embodiments, at least one of the one or more planar control portions may have a surface area of ​​at least 10 cm 2 , preferably at least 15 cm 2 , more preferably at least 20 cm 2 , most preferably at least 25 cm 2 may have a surface area of

[0028] Surface area should be understood as the surface area of ​​one of the planar control portions, one or more of which are arranged in the shoe for better foot positioning, balance, and stability of the user. The planar control portion may have any geometric shape, for example, at least 2 cm 2 , preferably at least 2.5 cm 2 , more preferably at least 3 cm 2 , most preferably at least 4 cm 2 It is contemplated that the shoe may be circular or rectangular in shape with a surface area of ​​at least 2 cm. 2 , preferably at least 2.5 cm 2 , more preferably at least 3 cm 2, most preferably at least 4 cm 2 However, a shoe may have one or more planar control portions, each having the same surface area of ​​at least 2 cm. 2 , preferably at least 2.5 cm 2 , more preferably at least 3 cm 2 , most preferably at least 4 cm 2 Another possibility is for one or more planar control portions to each have a different surface area. Typically, the larger the control portion, the more effective the control of foot positioning.

[0029] Generally, in various embodiments, the control portion may be formed from several sub-portions arranged on one surface. For example, a 4 cm 2 The control parts are arranged on the same surface, each 1 cm 2 Preferably, the sub-portions forming the control portion are positioned close to each other with or without a space between them.

[0030] In various embodiments, at least one of the one or more planar control portions may include a texture.

[0031] Texture relates to surface finish and should be understood as the placement, orientation, and distribution of particles (e.g., grains or crystals) within a material to improve grip of the planar control portion through increased friction and interlocking surface irregularities, which improves foot positioning and therefore postural control of the user. Furthermore, this allows for better friction and traction in the shoe by improving tactile feedback and preventing the formation of a fluid film.

[0032] For example, the texture may be an arrangement of grooves, scratches, parallel lines, or circles. It is contemplated that the texture of at least one of the one or more planar control portions may have a different material than the rest of the shoe for better grip and friction during use.

[0033] In various embodiments, at least one of the one or more planar control portions may be smooth to reduce grip and / or allow for smoother sliding over a surface.

[0034] Smooth relates to a smooth, non-textured surface due to the slippery properties of at least one of the one or more planar control portions and may be understood as smooth, gliding, slippery, or slippery.

[0035] For example, when performing handstand push-ups, a planar control portion in direct contact with the surface, i.e., the wall, allows for a smoother glide against the wall.

[0036] In various embodiments, the shoes of the present invention may include textured and / or non-textured surfaces on the sole and / or upper for improved positioning and guidance. For example, the sole and / or upper may include textured zones for improved grip and stability on surfaces, and non-textured zones may provide better alignment with the surface, and thus increased stability, while also allowing for smooth movement depending on the needs of the user and the particular activity being performed.

[0037] In various embodiments, at least one of the one or more planar control portions may have a surface texture that is different from the surface texture of the remainder of the sole surface and / or shoe upper.

[0038] The different surface textures relate to different materials or textures on at least one surface of one or more planar control portions that enhance foot positioning control. The different surface textures are useful for addressing individual planar control portions to individually design different portions of the shoe. Furthermore, the individually addressed planar control portions of the shoe may be tailored to the specific needs of the user.

[0039] The remaining shoe surface relates to the shoe not consisting of the planar control portion. For example, a planar control portion located in the heel portion may have a different surface texture than the remaining heel portion of the shoe. It is also contemplated that the planar control portion in the heel portion may have a different surface texture than, for example, the midfoot, forefoot, or toe portion of the shoe.

[0040] In various embodiments, at least one of the one or more planar control portions may be visually distinct from the remainder of the sole surface and / or shoe upper.

[0041] Visually distinct refers to, for example, different textures, colors, materials, shapes, etc. for a better feedback mechanism to the user. For example, when using the shoe of the present invention, the user visually recognizes whether the foot, and therefore the user's overall posture, is in the correct position. The remaining shoe surface refers to the shoe that is not composed of a planar control portion.

[0042] At least one of the one or more planar control portions may be located near the center of the toe area, preferably at the toe cap, and configured to control the positioning of the user's feet when performing push-ups.

[0043] Push-ups are a common bodyweight exercise that primarily targets the chest, shoulders, triceps, and core muscles. The push-up position is characterized by lying face down on the floor with the body supported on the hands and toes.

[0044] Typically, the user faces the floor and assumes a position parallel to a surface, eg, the floor, with their feet positioned at right angles, ie, with their toes pointed towards the floor.

[0045] At least one or more planar control portions are located near the center of the toe area when performing a push-up, providing stability and improved foot positioning during the exercise. The remainder of the shoe preferably does not contact the surface during the exercise, only the planar control portions. The planar control portions are microstructured, but may also provide planar portions or may have both planar and structured portions.

[0046] The shoe may include at least first and second planar control portions located near the center of, and preferably at, the heel portion and configured to control the positioning of the user's foot when performing a forward lunge.

[0047] A forward lunge is a lower body exercise that involves stepping forward with one leg while the other leg remains stationary behind. It is commonly used to target and strengthen the muscles of the thighs, hips, and glutes. For example, when performing a forward lunge, the exerciser typically needs to take a large step with the front of the foot and land in a stable position with that same foot. The first and second control points provide stability during this step of the forward lunge exercise.

[0048] In various embodiments, the first control portion and the second control portion may be immediately adjacent to each other, with the normal of the first planar control portion being at an angle to the normal of the second planar control portion.

[0049] The first control portion and the second control portion are immediately adjacent to each other in the sense that they are in direct contact with each other and are positioned so as to share a common edge of the shoe.

[0050] The normals of the first and second control portions are angled relative to one another, which results in the second planar control portion being angled relative to the first planar control portion.

[0051] For example, when performing a forward lunge, the user needs to take a big step forward and land in the correct position with the front of the foot.

[0052] By providing at least two planar control portions angled toward each other, the user's foot first strikes the first planar control portion perpendicular to the surface of the sole and is then guided to the second, "angled" planar control portion. The first and second planar control portions help stabilize and guide the user's foot during movement.

[0053] In various embodiments, the interior angle between the first control portion and the second control portion may be between 100° and 160°, preferably between 120° and 150°, and more preferably between 130° and 130°.

[0054] An interior angle between 100° and 160°, preferably between 120° and 150°, more preferably between 130° and 130° allows for improved guidance and stability of the sole.

[0055] The interior angle should be understood as the inward angle between two planar control portions along the longitudinal axis of the shoe. For example, if the first and second planar control portions are located in the heel portion, the interior angle will point inward toward the center of the shoe.

[0056] At least one of the one or more planar control portions may be located on, and preferably at, the heel portion and configured to control the positioning of the user's feet when performing handstand push-ups.

[0057] At least one of the one or more planar control portions is preferably located on the heel portion, more preferably on the center of the outermost distal portion of the heel portion. For example, when performing handstand push-ups, a user leans against a wall to perform a handstand. To do so, the user assumes an upside-down position and supports their weight using only their hands, while for stability reasons, the user keeps their feet, particularly their heels, leaning against the wall. During this exercise, a smooth one or more planar control portions provides improved alignment and positioning against the wall, leading to better stability and balance while the heels are leaning against the wall. Furthermore, a smooth one or more planar control portions allows the heels to slide more easily along the wall while performing handstand push-ups, thereby enabling improved, smoother lower body movement.

[0058] When performing push-ups using the shoe of the present invention, the heel provides stable positioning during handstands and also provides improved foot control as the foot slides up and down the wall during push-ups.

[0059] At least one of the one or more planar control portions may be positioned laterally and / or medially in the midfoot portion, forefoot portion, and / or heel portion and configured to control the positioning of the user's foot when performing a side plank.

[0060] "To the side, medial, posterior or anterior to the midfoot, forefoot and / or heel area" should be understood as placement anywhere on the outermost edge of the midfoot area, forefoot area and / or heel area of ​​the sole.

[0061] The side plank is a core-strengthening exercise that targets the side muscles of the torso, including the obliques. For example, to perform a side plank, a person lies on their left or right side on a mat, places the corresponding forearm on the ground, and lifts their lower back to create an oblique support.

[0062] The user places one foot on a surface and the second foot on top of the first foot, which is in contact with the surface. The foot in contact with the surface, such as a mat, supports the body weight on the outer lateral region.

[0063] When using the shoe of the present invention, a user finds a stable position and receives improved balance support from the shoe during exercises such as a side plank and / or a Copenhagen plank, where the user's foot is in contact with a surface (e.g., the ground or an object) with the inside of the shoe.

[0064] The shoe may include at least first and second planar control portions located laterally and / or medially of the forefoot portion and configured to control the positioning of the user's foot when performing skater jumps.

[0065] Skater jumps are dynamic, strengthening exercises that engage multiple muscle groups, including the lower body and core, and stabilizing muscles. They mimic the lateral movement of a skater on ice and are often included in agility and cardiovascular training.

[0066] When performing a skater jump, the athlete jumps laterally to one side and lands on the opposite leg with a slight bend in the knee. As the athlete lands on one leg, the other leg is positioned slightly across the body behind and suspended above the ground. Finally, the athlete pushes off the landing leg and jumps laterally to the other side, repeating the process.

[0067] The first and second control portions provide stability and balance during subsequent jumps and landings. Specifically, the two planar control portions are positioned such that a user can land on one of the first and second planar control portions and simultaneously be guided to the second planar control portion, which enhances stability and balance during the movement.

[0068] According to the preceding embodiment, the first and second control portions may be immediately adjacent to each other, and the normal of the first planar control portion may be inclined relative to the normal of the second planar control portion.

[0069] For example, in a skater jumping motion, the angled first and second planar control portions position the feet in the correct position, leading to improved stability and balance for the user.

[0070] Generally, the angled arrangement allows the shoe to better guide movement during exercise. Specifically, the user lands on a first planar control portion that positions the foot, and then, during a lateral jump, for example, the foot is guided to an adjacent second planar control portion that is angled relative to the first planar control portion.

[0071] According to the preceding embodiment, the interior angle between the first control portion and the second control portion may be between 100° and 160°, preferably between 120° and 150°, and more preferably between 130° and 130°.

[0072] An interior angle between 100° and 160°, preferably between 120° and 150°, more preferably between 130° and 130° allows for improved guidance and stability of the sole.

[0073] The interior angle should be understood as the inward angle between the two planar control portions along the longitudinal axis of the shoe. For example, if the first and second planar control portions are located in the heel portion, the interior angle points toward the center of the shoe.

[0074] In various embodiments, at least one of the one or more planar control portions may have a length of at least 3 cm, preferably at least 3.5 cm, and most preferably at least 4 cm, and a width of at least 0.5 cm, preferably at least 0.8 cm, and most preferably at least 1 cm. In some cases, the planar control portion may have a length of at least 15 cm, preferably at least 20 cm, and most preferably at least 25 cm.

[0075] For example, a length of at least 3 cm, preferably at least 3.5 cm, and most preferably at least 4 cm provides a sufficiently long axis to enhance stability when stress is placed on the planar control portion, e.g., when weight is primarily placed on the planar control portion.

[0076] Similarly, a width of at least 0.5 cm, preferably at least 0.8 cm, and most preferably at least 1 cm, in combination with the length is sufficient to provide improved stability and balance.

[0077] It is contemplated that a shoe may include two or more planar control portions, and that at least one of the one or more planar control portions may have a different length (e.g., longer or shorter) and width (e.g., wider or narrower) than the other planar control portions of the one or more planar control portions.

[0078] For example, a first planar control portion may be located centrally on the outermost side of the toe cap and have a square shape and a length of, for example, 2 cm and a width of, for example, 1 cm, and a second planar control portion may be located laterally and medially in the lateral foot region of the forefoot portion and have a length of, for example, 4 cm and a width of, for example, 0.5 cm. The planar control portions can be various shapes, such as square, round, rectangular, oval, triangular, or any other known shape.

[0079] At least one of the one or more planar control portions is made from one or more of thermoplastic polyurethane (TPU), liquid TPU, ethylene vinyl acetate (EVA), rubber, and / or a foam composite.

[0080] For example, TPU is a versatile polymer that combines the properties of rubber and plastic. It is known for its durability, flexibility, and resistance to abrasion, oil, and chemicals. Liquid TPU or TPU is preferably used for flat control due to its excellent flexibility and toughness. It provides good support and shock absorption and is often used in sports and outdoor footwear.

[0081] These materials may be used during injection molding. At least one of the one or more planar control portions may further be made from one or more of a thermoplastic elastomer (TPE) material, a polyamide (PA) material, a polyurethane (PU) material, such as polyether block amide (PEBA), polyamide 11 (PA11), polyamide 12 (PA12), and / or a thermoplastic polyurethane (TPU), such as liquid TPU or a TPU with a Shore A hardness of 95. Other materials or mixtures of materials are also possible.

[0082] In various embodiments, at least one of the one or more planar control portions may have a radius of curvature of at least 5 m, preferably at least 7 m, and more preferably at least 10 m. The radius of curvature is most preferably at least 50 m. Thus, at least one of the one or more planar control portions is very flat / even to stabilize and control the foot when in contact with the ground. In other words, to provide the required "flatness" of at least one of the one or more control portions to enable stabilization and "anchoring" of foot position, at least one planar control portion has a radius of curvature that is significantly higher than those known in the art, i.e., at least 5 m, preferably at least 7 m, and more preferably at least 10 m.

[0083] In various embodiments, at least one of the one or more planar control portions may be located on the lateral and / or medial sides of the shoe (10). At least one of the one or more planar control portions may be located on either one or both sides of the shoe. For example, planar control portions may be located only on the lateral sides of the shoe. In some embodiments, planar control portions may be located only on the medial side. Thus, the shoe of the present invention may include planar control portions on the lateral and / or medial sides, which may allow for better and improved foot positioning and control during certain athletic activities.

[0084] In various embodiments, at least one of the one or more planar control portions may be located at the front and / or rear of the shoe (10). At least one of the one or more planar control portions may be located on either or both sides of the shoe. Thus, the shoe of the present invention may include planar control portions on the front, rear, or both sides, which may allow for better and improved foot positioning and control during a particular athletic activity. While not all possible combinations are explicitly mentioned or described above, the features of the described embodiments of the shoe or other options and features of the first aspect may be combined to achieve desired athletic and performance characteristics of the shoe. Individual features and subfeatures may be omitted if not essential to achieve the desired results.

[0085] In various embodiments, the shoe may be a sports shoe.

[0086] Sports shoes may be used for example for gym exercise, and it is envisaged that the sports shoes may be used indoors and out, and may optionally have a high level of cushioning whilst providing improved stability and control features for the shoe.

[0087] It is emphasized that all aspects, features, and options described and disclosed above in the context of the first aspect may be applied to or combined with the description and disclosure of the second aspect, and vice versa, unless physically or technically precluded, even if every possible combination or subcombination of features is not explicitly set forth below. Accordingly, the technical advantages of such options and features already described above will not be repeated in detail, at least to the same extent, and instead reference is made to the corresponding above description for the sake of brevity.

[0088] The present invention includes the following embodiments. [1] Shoes (10), especially sports shoes, The device includes one or more planar control portions (21, 22, 24, 26, 26a, 26b, 28) configured to contact a surface when performing a particular exercise to control the positioning of the user's foot during exercise.

[0091] Possible embodiments of the invention and different aspects of the present disclosure are described below primarily with respect to sports shoes, but it is again emphasized that the different aspects may be implemented in different types of soles and shoes and are not limited to the specific embodiments described below.

[0092] Furthermore, it is noted that only individual embodiments may be described in detail below. Those skilled in the art will understand that the features and possible variations described with reference to those specific embodiments may be further modified and / or combined with each other in different forms or subcombinations without departing from the scope of the present invention and the present disclosure. Individual features and subfeatures may be omitted if they are not essential to achieve the desired results. Therefore, to avoid redundancy, reference is made to the preceding paragraphs that also apply to the following detailed description.

[0093] 1 shows details of a shoe 10, in particular a sports shoe, comprising a sole 1 and several planar control portions 26, 28 configured to contact a surface when performing a particular exercise to control the positioning of a user's foot during exercise. Exercises utilizing the control portions 26 and 28 will be described in more detail with reference to FIGS. 4a and 4b.

[0094] As can be seen in FIG. 1, the planar control portions 26, 28 are located on the medial side of the forefoot portion 38 of the shoe in this embodiment.

[0095] As can be seen in FIG. 1 , the shoe includes a first planar control portion 26 and a second planar control portion 28, which are directly adjacent to each other, with the normal of the first planar control portion 26 inclined relative to the normal of the second planar control portion 28. The first planar control portion 26 and the second planar control portion 28 are disposed on the sole, with the first planar control portion 26 disposed longitudinally in double mounts 26a and 26b relative to the contact surface 30 of the sole, particularly where the sole overlaps the shoe upper. In other words, the planar control portion 26 is divided into two portions 26a and 26b. As can be seen from the figure, the two portions 26a and 26b are partially textured. The second planar control portion 28 is disposed adjacent to the contact surface 30 at an angle relative to the contact surface 30.

[0096] Each planar control portion 26, 28 is at least 2 cm 2 The first planar control portion 26 may be smooth to reduce grip and / or allow for smooth sliding over a surface, and the second planar control portion 28 may have a texture 28' (e.g., striped) to enhance grip.

[0097] 1, the planar control portions 26, 28 are positioned laterally of the front foot 38 to control the positioning of the user's foot when performing a side plank. The first planar control portion 26 and the second planar control portion 28 are immediately adjacent to each other, and the normal of the first planar control portion 26 is at an angle to the normal of the second planar control portion 28.

[0098] As can be seen in Figure 1, the planar control portions 26, 28 are partially flat and partially textured. In other words, the planar control portions of Figure 1, and generally all embodiments, have a high radius of curvature (at least 1 mm), which, due to the inherent surface, length, and width size of the sole, results in essentially, if not completely, flatness with virtually no perceptible curvature. Shoes known in the art are typically highly curved to conform to the shape of the foot, and therefore always have a fairly large radius of curvature to conform to the natural shape of the foot.

[0099] Figures 2a and 2b show front views of the shoe of Figure 1. As shown, the shoe also comprises, in its toe area, another planar control portion 21 adapted for better control during push-ups.

[0100] 2a, the sports shoe 10 is shown in a front view with the planar control portion 21 positioned near the center of the toe portion 32, specifically in the center of the toe cap, to control the positioning of the user's foot when performing push-ups. The planar control portion 21 shown in FIG. 2a is perpendicular to the ground contact surface 30 of the sole.

[0101] In FIG. 2a, the planar control portion 21 has a length of approximately 3 cm and a width of about 2 cm. Specifically, when using the embodiment shown in FIG. 2a, a user controls the position of the foot when placing weight on the toe cap, for example, when performing a push-up. This particular movement can be seen in detail in FIG. 2b, which shows the sole 1 and the sports shoe 10 of FIG. 2a in a 90° tilt position. FIG. 2b illustrates the placement of the foot on the planar control portion 21 of the toe cap during a push-up. The planar control portion 21 in this particular area, i.e., the toe area 32, is in full contact with the surface, typically the ground, when performing the exercise, resulting in a stable and correct foot position.

[0102] The planar control portion 21 in FIG. 2a has a surface texture that is different from the surface texture of the remaining sole surface and shoe upper, which are striped and textured. The term "remaining sole surface and shoe upper" refers to the portions of the sole surface and shoe upper that are not the control surface. The planar control portion 21 in FIG. 2a has a different surface texture, making it visually distinct from the remaining sole surface. As can be seen in FIG. 2a, the material used for the planar control portion 21 and the material used for the remaining sole are the same. Suitable materials for manufacturing the shoe of the present invention can be one or more of thermoplastic polyurethane (TPU), ethylene vinyl acetate (EVA), rubber, and / or foam composites. A preferred material for use in the planar control portion is liquid TPU.

[0103] Figure 3a shows the heel area of ​​sports shoe 10 having sole 1, and Figure 3b shows shoe 10 when performing a forward lunge. In particular, shoe 10 comprises additional first and second planar control portions 22, 24 located near the center of heel portion 34, i.e., at the heel portion, and configured to control the positioning of the user's foot when performing a forward lunge.

[0104] This particular movement can be seen in detail in Figure 3b, which shows the sole 1 and sports shoe 10 of Figure 3a in an approximately 60° tilt position. Figure 3b illustrates the placement of the foot on the planar control portion 22 at the heel during a forward lunge. As can be seen in Figure 3a, the first control portion 22 and the second control portion 24 are immediately adjacent to each other, e.g., side-by-side, and share a common edge. The first planar control portion 22 is positioned below the second planar control portion 24.

[0105] The planar control portions 22, 24 are inclined relative to each other, i.e., the perpendicular of the first planar control portion 22 is inclined relative to the perpendicular of the second planar control portion 24. This angle, i.e., the inward inclination angle between the first control portion 22 and the second control portion 24, is between 100° and 160°. For some exercises, this angle may be greater than 160° (not shown). In particular, this angle may be adjusted depending on the exercise. In some cases, a larger or smaller angle is desirable. The latter depends on the foot position that requires stability throughout the exercise. As can be further seen, the first and second control portions 22, 24 are spaced apart by approximately 2 cm, respectively. 2 has a surface area of

[0106] Figure 4a shows the shoe 10 from the same perspective as Figure 1. Figure 4b shows the shoe 10 in position for performing a skater jump. As can be seen, the shoe 10 is positioned at a 45° angle, with the foot resting entirely on the second planar control portion 28. The flatness of the planar control portion 28 stabilizes the athlete's posture during this portion of the exercise.

[0107] Figure 5a shows the shoe 10 of the present invention when performing a push-up, and Figure 5b shows a shoe not of the present invention for comparison. As can be seen in Figure 5a, a user using the sports shoe 10 of the present invention with the sole 1 has correct foot positioning when performing a push-up. The foot has a correct vertical alignment, and the weight is resting on the toe cap of the shoe 10 with the planar control portion 21. In Figure 5b, it can be seen that the foot is tilted rather than vertical, reducing the efficiency of the exercise.

[0108] 6a and 6b show a user performing a side plank. In FIG. 6a, the shoe 10 of the present invention is used, while FIG. 6b shows a regular sports shoe without the planar control portion of the present invention. In FIG. 6a, a user using the sports shoe 10 of the present invention with the sole 1 has correct foot positioning when performing a side plank. The user's weight is placed on the planar control portion 28. The lines indicate the user's lateral position during the side plank. In contrast, in FIG. 6b, the user's ankle is tilted, which reduces the efficiency of the exercise and potentially injures the ankle joint.

[0109] It is noted that, as will be understood by those skilled in the art, the above embodiments and / or examples may be combined with further aspects described herein, and details of the embodiments and / or examples may 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 figures. [Explanation of symbols]
