Description

Technical Field

[0001] This disclosure relates to the field of footwear, and more particularly to a type of footwear. Background Technology

[0002] In the footwear industry, shoes are typically designed with a variety of features aimed at enhancing comfort, performance, and durability. Known systems generally involve fixed structures and components integrated into the shoe during the manufacturing process. These components, such as support frames, linings, and tensioning elements, are usually permanently attached to the shoe, limiting the ability to customize or modify the shoe to meet the wearer's specific needs.

[0003] Based on known designs, athletic shoes, especially running shoes, are constructed with a focus on stability, cushioning, and support. However, these shoes often lack versatility in terms of adjustability and personalization. For example, the support structure within the shoe is typically rigid and fixed, which may not be able to adapt to the diverse foot shapes and biomechanical requirements of different users. Furthermore, the attachment mechanisms for functional components are often permanent, limiting the ability to replace or adjust these components based on changing conditions or preferences.

[0004] US 2024 / 0099422 A1 discloses a footwear article having an upper attached to a sole structure, wherein the sole structure includes a midsole located between an insole and an outsole.

[0005] DE 10 2015 200 523 B4 relates to a sock-shaped outer shoe that is detachably arranged around a skeleton to provide a modular shoe, particularly an athletic shoe.

[0006] Despite substantial progress in footwear design, greater flexibility and customization are still needed. Current approaches do not adequately address the need for modularity in shoe construction—that is, components that can be easily removed, replaced, or adjusted. This limitation impacts the overall performance and comfort of the shoe, as well as its adaptability to different activities or environmental conditions. Furthermore, the lack of modularity leads to increased wear and tear, as users cannot replace worn components without replacing the entire shoe.

[0007] Therefore, a technical problem constituting the present invention is to provide a shoe design that at least partially overcomes the shortcomings of known systems. Summary of the Invention

[0008] The above-mentioned objectives are achieved, at least in part, through embodiments of this application. Preferred embodiments are provided below, and those skilled in the art will find clues to other suitable aspects of the invention from the overall disclosure of this application.

[0009] One aspect of the invention relates to a shoe comprising: a modular rim system including a support frame adapted to receive and removably hold functional components; and a sole wherein the support frame is integrated into the sole of the shoe.

[0010] The support frame serves as a foundational structure, allowing various components to be attached via various methods (such as threaded connections) to provide structural support for the sole. This modular design enables customization based on the user's training needs and preferences. The ability to attach different support elements (such as a midfoot cage or heel stabilizer) allows for customized support and enhanced performance. Advantages include flexibility in adapting the shoe to different terrains and training requirements, providing a personalized fit, and improved training outcomes. Furthermore, the ability to replace worn parts of the shoe extends its lifespan, increasing its sustainability.

[0011] When the shoe is an athletic shoe, especially a running shoe, further improvements can be made.

[0012] Running shoes with this system allow runners to change different cushioning levels or outsole traction components based on terrain (e.g., road running vs. trail running). This adaptability enhances comfort, performance, and durability by allowing users to replace worn parts rather than the entire shoe. The ability of this modular rim system to receive and retain functional components indicates that the shoe can be customized or adjusted to the user's needs, providing features such as cushioning, enhanced stability, or improved grip. The support frame integrated into the sole demonstrates a seamless design that improves overall shoe performance by providing a stable and supportive base. For example, athletes can change cushioning during a run for additional shock absorption or install specialized treads for improved grip on different surfaces. This modular design enhances customization, extending shoe life by allowing worn parts to be replaced rather than discarding the entire shoe, and providing adaptability to various sports or environmental conditions.

[0013] Further improvements can be made when the support frame includes joints suitable for attaching functional components.

[0014] Such joints can use snap-fit ​​mechanisms, screws, or interlocking connectors to attach components such as custom cushioning pads, stability inserts, or interchangeable outsole treads. For example, athletes can switch to a high-traction outsole for slippery conditions or use additional heel support for long-distance running. In this context, a joint is a connection point designed to attach various functional components, such as interchangeable support elements, to a shoe. These joints are adapted to facilitate the attachment process and allow for customization based on individual needs.

[0015] When the connector includes a mechanical, magnetic, or adhesive fastening mechanism, it can be further modified, including but not limited to wire, magnetic attachment means, snap-fit ​​systems, belts, hook and loop fasteners, straps, buckles, or snap-fit ​​connections.

[0016] These features enhance the shoe's versatility and adaptability by allowing various components to be securely attached and easily replaced or adjusted. The inclusion of multiple fastening options provides design and functional flexibility. For example, runners can use snap-on attachment friction pads for trail running and switch to a smooth sole for indoor training. This variety of fastening options enhances ease of use, durability, and customization, allowing users to tailor their shoes for different activities and conditions.

[0017] Further improvements can be made when the support frame is adapted to allow functional components to be attached to the support frame via screws.

[0018] This enablement of the support frame through screw-attached fitting means that these components can be securely fastened and easily replaced or customized. This modular design offers advantages including the ability to customize the shoe to individual needs and preferences, enhancing comfort and performance for different types of training and terrain. For example, a runner can attach a cushioned midsole for long-distance running and later switch to a stiffer midsole for sprinting.

[0019] Further improvements can be achieved when the support frame includes a profile that substantially corresponds to the shape of the sole.

[0020] With this support frame that follows the outer contour of the sole, it can serve as a reinforcing structure, improving stability and durability, while allowing functional components to be attached along the edges.

[0021] Alternatively, if the support frame follows the internal contours of the sole, it can serve as an internal mounting system for cushioning inserts or support plates.

[0022] The support frame is a structural component that provides stability and support to the shoe. The sole is the bottom part of the shoe that contacts the ground. Matching the contours of the support frame to the contours of the sole means that the shape and form of the support frame are closely aligned with the shape and form of the sole. This alignment ensures a seamless fit between the support frame and the sole, enhancing the structural integrity and stability of the shoe.

[0023] Further improvements can be made when the support frame includes a flat, elongated structure, particularly a band, which is arranged to follow the contour of the sole.

[0024] A flat structure extending longitudinally along the sole can serve as a stabilizing band around the sole perimeter, providing lateral support and acting as a mounting point for grip elements or protective components. In this case, the support frame has a vertical profile, meaning it has a significant vertical extension but a smaller extension in the direction perpendicular to the sole edge portion.

[0025] Alternatively, if the flat structure extends in the lateral direction of the sole (e.g., from the mid-side to the lateral side), it can serve as a thin reinforcing layer embedded within the sole, providing a low-profile attachment surface for, for example, modular cushioning or shock-absorbing inserts. In this case, the support frame is flat in the height direction of the shoe, i.e., it has a horizontal profile.

[0026] The support frame can also include a combination of vertical and horizontal profiles. For example, the support frame can have an angular cross-section or a T-shaped cross-section. In this case, one arm forming the angle or the T can extend substantially horizontally, while the other arm can extend substantially vertically.

[0027] This embodiment can be further improved when the flat, elongated structure forms a U-shape with an opening at the front of the sole.

[0028] This U-shaped structure wraps around the heel and midfoot area, acting as a reinforcing frame to enhance heel stability and arch support while maintaining forefoot flexibility for natural movement. This configuration is beneficial for running shoes, where rearfoot support is important for cushioning, while the open front allows unrestricted toe movement for better propulsion. The open front feature promotes greater freedom of movement and flexibility for the wearer because it reduces constraint on the forefoot area.

[0029] Further improvements can be achieved when the joints are arranged circumferentially around the support frame, especially at uniform intervals.

[0030] This circumferential and evenly spaced arrangement of joints ensures a balanced distribution of forces and a uniform range of customization options.

[0031] Further improvements were achieved when at least one connector was positioned in the heel area adjacent to the shoe.

[0032] This heel connector can be used to attach cushioning inserts, stability plates, heel stabilizers, or interchangeable outsole sections. For example, runners can install a cushioning element to reduce impact during long runs, or install a stiffer stabilizer to increase heel support during sprints. Placing the connector near the heel improves adaptability, enhances comfort, and extends shoe life by allowing users to replace worn or activity-specific parts as needed. The "heel area" is the part of the shoe that supports the heel.

[0033] Further improvements can be made when the shoe includes at least one functional component, wherein the functional component includes a set of lines adapted to stabilize the midfoot of the shoe wearer, and also includes attachment means configured to facilitate attachment to a support frame.

[0034] These threads are integrated into the shoe's design to provide enhanced support and stability during use, beneficial for running or other athletic activities. Furthermore, this functional component includes attachment means configured to facilitate its connection to the support frame. This type of thread can be tension fibers or reinforcing bands integrated into the midfoot area of ​​the shoe to enhance lateral stability and arch support. Attachment means can include snap-fit ​​connectors, hook-and-loop fasteners, or screw-in points for customization. For example, athletes requiring additional midfoot support for sprinting can attach an enhanced stability structure, while long-distance runners may prefer a more flexible setup. This modular design improves foot stability, injury prevention, and overall performance adaptability.

[0035] When the set of lines includes at least three lines, it can be further improved, with two lines intersecting on the outside of the midfoot and / or forefoot area of ​​the shoe, and one line wrapping around the heel area of ​​the shoe.

[0036] This configuration enhances midfoot and forefoot stability, providing the wearer with additional support and safety. The crisscross stitching on the lateral side ensures the midfoot and forefoot are securely held in place, reducing the risk of injury and improving overall comfort. The stitching around the heel provides further stability, ensuring proper heel support and minimizing movement within the shoe.

[0037] This embodiment can be further improved when at least one line includes a first end and a second end, with the first end attached to the front region of the support frame and the second end attached to the rear region of the support frame.

[0038] This configuration allows the line to at least partially enclose the midfoot region. The anterior region of the support frame corresponds to the area aligned with the metatarsophalangeal joint of the foot, the midfoot region corresponds to the area aligned with the metatarsal shaft, and the posterior region corresponds to the area aligned with the tarsometatarsal joint. This feature enhances the stability of the midfoot region by ensuring that the line encloses it, which helps to distribute pressure more evenly.

[0039] Further improvements can be made when at least one line extends upward and backward in a curved trajectory to wrap around the heel portion of the shoe.

[0040] These curved lines act similarly to adaptive reinforcement structures, tightening around the heel and midfoot during movement. This helps prevent heel slippage and improves foot lock-up, which is useful for sports like running, basketball, or soccer, where stability is crucial during rapid changes of direction. For example, sprinters might experience better power transfer and energy return, while hikers might benefit from enhanced heel support on uneven terrain. This design improves comfort, performance, and injury prevention, providing a safe and adaptive fit.

[0041] Further improvements can be made when the shoe includes at least one functional component, wherein the functional component includes an upper lining element configured to cover at least a portion of the upper surface of the shoe, and also includes an attachment means configured to facilitate attachment to a support frame.

[0042] Such upper lining elements can be reinforced shells, stretchable fabric sheets, or protective covers to enhance support, durability, or weather resistance. Attachment methods can include snap-on connectors, hook-and-loop fasteners, zippers, or magnetic buckles for easy removal and replacement. For example, runners can attach a breathable mesh cover in hot weather and switch to a waterproof cover in wet conditions.

[0043] Further improvements can be made when the shoe includes at least one functional component, wherein the functional component includes at least one inverted V-shaped support structure, wherein the inverted V-shaped arm includes attachment means configured to facilitate attachment to the support frame.

[0044] Alternatively, the attachment means may include a plurality of closely spaced attachment points on the support frame and / or a sliding attachment mechanism to allow fine-tuning of the angle between the V-arms.

[0045] This V-shaped support structure can serve as a reinforcing element, enhancing support while maintaining flexibility. Attachment methods can include multiple closely spaced attachment points or a sliding attachment mechanism, allowing for fine-tuning of the V-shape's angle and positioning. For example, runners can adjust the V-shape to provide more arch support during long runs or to add lateral stiffness for high-impact sports like basketball. The flexing element allows for dynamic adaptation during movement, improving comfort while maintaining structural integrity and foot lock-up. Furthermore, each wearer may have slightly different foot bone structures. By giving the wearer the flexibility to adjust the individual adjustment points of the inverted V-shaped functional components, the user can precisely customize the shape of the V-shape to suit their heel stability requirements.

[0046] Further improvements can be made when the shoe includes at least one functional component, wherein the functional component includes a rigid or semi-rigid body having a generally elongated shape adapted to conform to the profile of a support frame, and specifically includes a convex curved edge facing the ground, the convex curved edge being configured to facilitate natural rolling motion during the wearer's stride when the functional component is attached to the support frame.

[0047] This component acts as a rocker element, while its convex shape facilitates a smooth transition from heel to toe. The ability to replace or adjust this component allows for customization based on the wearer's activity type or foot mechanics. Benefits include improved gait efficiency and comfort for the wearer, as the rolling motion reduces impact and enhances stride smoothness. The optional tapered edge of the body can further contribute to a seamless transition between strides, making the shoe suitable for various terrains and training needs.

[0048] Further improvements can be made when the shoe includes at least one functional component, wherein the functional component includes an elastic tensioning element comprising an elongated body and attachment means at opposite ends configured to secure the elastic tensioning element to a support frame.

[0049] Attachment mechanisms allow for positional adjustments to accommodate changes in the user's foot structure and joint positioning. Tensioning elements can be made of elastic materials such as rubber, elastomers, or non-Newtonian materials such as shear-thickened or viscoelastic polymers. These materials enable the element to stretch under gradual stress and resist deformation under sudden force. Advantages include enhanced customization and adaptability to individual user needs, providing tailored support and improved training effectiveness.

[0050] Such elastic tension elements can act as dynamic support bands, adapting to foot movements while maintaining stability. The attachment method allows for positional adjustment to accommodate differences in arch height, gait mechanics, and joint positioning. Furthermore, the elastic tension element exhibits a spring-like or propulsive effect due to its pretension, which helps propel the wearer's foot forward. Therefore, the elastic tension element can store and release energy to support the wearer's gait cycle.

[0051] This embodiment can be further improved when the tensioning element extends along the body-side portion of the support frame and includes a first attachment point at one end of the tensioning element and a second attachment point at the opposite end of the elongated tensioning element, wherein the first attachment point is configured to pivotally attach to the front portion of the support frame and the second attachment point is configured to pivotally attach to the rear portion of the support frame, wherein the tensioning element is configured to transmit force between the front and rear portions of the support frame.

[0052] This pivotable attachment point allows the tensioning element to act as a dynamic link, adapting to foot movement while providing controlled resistance and support. For example, long-distance runners may experience reduced fatigue and improved stride efficiency, while athletes in high-impact activities may benefit from better shock absorption and propulsion. This enhancement to rocker behavior is important for optimizing shoe performance by adapting to changes in foot structure and joint positioning while maintaining the shoe's structural integrity during movement, providing better support and comfort for the user.

[0053] Further improvements were made when the support frame included a plate or a portion thereof.

[0054] This shoe is part of a modular system that allows for customization by attaching various components via screw joints. The support frame, as a structural element, provides stability and support to the shoe. Plates within the support frame enhance the shoe's stiffness and durability, providing customized support based on individual training needs and terrain. These plates can be made of carbon or glass fiber, natural fibers, composites, or reinforced polymers, offering stiffness and responsiveness. If the support frame is part of a plate, it ensures seamless integration with other functional components, such as modular cushioning elements or rocker structures. Attached Figure Description

[0071] The following sections provide a detailed description of embodiments of the invention, with reference to the accompanying illustrations for clarity. These descriptions are illustrative only and are not intended to limit the scope of the invention. The same reference numerals in the figures and text denote the same parts. The illustrations may not reflect actual dimensions or scales; for better understanding and visual convenience, their dimensions, scales, and elements may be depicted with enhancements. Figure 1A A support frame 110 is shown, which will be integrated into the sole of the shoe, which will be referenced. Figure 1B and Figure 1C The support frame 110 includes a plurality of joints 130 around its perimeter, which allow attachment of one or more functional components, which will be described in more detail herein. The support frame 110 is depicted as a flat, elongated structure that, in this embodiment, forms a U-shape opening at its front end (the toe section or forefoot region of the shoe in which the support frame will be integrated). Generally, although the support frame in the figures is shown as generally U-shaped and opening towards the front end, there may also be a support frame forming a closed loop or having one or more openings in addition to or in place of the forefoot region.

[0072] Figure 1B A shoe 100 (partially shown) is illustrated, which includes a modular rim system integrated into a sole 120. The modular rim system includes... Figure 1A The support frame 110 shown is designed to receive and removably hold functional components. The support frame 110 is integrated into the sole 120 of the shoe 100, providing structural support and enabling the attachment of various functional components. The support frame 110 follows the contours of the sole 120, ensuring a secure fit and alignment with the overall design of the shoe. The support frame 110 is depicted as a flat, elongated structure, which in this embodiment forms a U-shape opening at the front end of the sole 120. This U-shaped configuration allows for flexibility in attaching functional components along the sides and rear of the shoe 100. The support frame 110 is equipped with a plurality of joints 130 adapted to attach functional components to the frame. These joints 130 are arranged circumferentially around the support frame 110, providing evenly spaced attachment points for the functional components. In other embodiments, the attachment points may not be evenly spaced. The connector 130 may include various fastening mechanisms, such as mechanical, magnetic, or adhesive systems, including wire, magnetic attachment means, snap-fit ​​systems, belts, hook and loop fasteners, straps, buckles, or snap-fit ​​connections.

[0073] Figure 1C The integration of the modular frame system within the sole 120 of shoe 100 is described in detail (in...). Figure 1C (Partially shown). The shoe includes a support frame 110 embedded in the sole 120. The support frame 110 is designed to receive and securely hold various functional components, enhancing the shoe's versatility and functionality. The support frame 110 is depicted as a flat, elongated structure that follows the contour of the sole 120, providing a stable base for attaching additional components. The figure highlights the presence of a joint 130 along the support frame 110. The support frame 110 is shown with a contour corresponding to the contour of the sole 120. This design ensures seamless integration of the frame with the shoe's structure, maintaining the overall aesthetic and functional integrity of the shoe 100. The joints 130 are arranged circumferentially around the support frame 110 and may be evenly spaced to distribute loads and stresses evenly across the entire shoe. The figure also shows the location of at least one joint adjacent to the heel area of ​​the shoe 100. The heel joint can serve as an anchor point for components designed to stabilize or cushion the heel, contributing to the overall ergonomic design of the shoe.

[0074] exist Figure 1B and Figure 1C In the exemplary embodiment shown, a functional component 512 attached to the support frame 110 is depicted. In this example, the functional component 512 forms a rocker element, which will be referenced... Figure 5A and Figure 5BA more detailed description follows. Generally, any type of functional component can be attached to the support frame according to the invention, and the invention is not limited to the type of functional component to be attached. Some examples of functional components will be described below.

[0075] Figure 2 An embodiment of shoe 200 is shown, illustrating a modular rim system integrated into the shoe's design. Shoe 200 is depicted as having a support frame 210 adapted to receive and removably hold functional components. The support frame 210 is integrated into the sole of the shoe, providing structural integrity and facilitating the attachment of various functional components. The support frame 210 is equipped with joints 230 strategically positioned to facilitate the attachment of functional components. Shoe 200 includes functional components, such as a set of lines 212 adapted to stabilize the wearer's midfoot region 202. The lines 212 are configured to cross on the outer side of shoe 200, particularly in the midfoot and forefoot regions. Furthermore, the lines 212 wrap around the heel region 201 of shoe 200, providing enhanced support and stability. The figure shows the trajectory of the lines 212, extending upward and backward in a curved path to wrap around the heel portion 201. The support frame 210 is designed to facilitate the attachment of the lines 212, with the first end of each line attached to the front region of the support frame 210 and the second end attached to the rear region, midfoot region, or rear-midfoot region. This configuration ensures that the lines 212 surround the midfoot region 202, helping to stabilize the wearer's foot during exercise.

[0076] Figure 3 An embodiment of a shoe 300 incorporating a modular frame system is shown. The shoe includes a support frame 310 integrated into the sole. The support frame 310 is designed to receive and removably hold functional components, enhancing the shoe's versatility and functionality. The support frame 310 is depicted as a flat, elongated structure that follows the contours of the sole. This structure forms a U-shape with an opening at the front of the sole, providing a secure and flexible base for attaching various functional components. The frame is circumferentially positioned around the sole, ensuring even distribution of any attached components. The figure illustrates multiple joints 330 arranged circumferentially around the support frame 310. Figure 3One of the functional components shown is an upper lining element 312. This element is configured to cover at least a portion of the upper surface of the shoe 300. The upper lining element 312 is attached to the support frame 310 using a connector 330, providing additional support and stability to the shoe. The upper lining element can be adjusted or replaced, allowing modifications to the appearance or functionality of the shoe. Exemplary functionalities include abrasion resistance, additional support, weather resistance, water resistance, and wind resistance. Exemplary modifications to the shoe's appearance include visual or aesthetic aspects such as surface texture, color, and feel. Thus, the upper lining element 312 can be replaced to adapt the shoe to different weather conditions, such as rain or low temperatures. Similarly, the visual appearance of the shoe can be modified according to the wearer's preferences. Possible materials for manufacturing the upper lining element 312 include knitted, woven, nonwoven, fabric, textile, foil, and TPU, to name just a few. Typically, the material may depend on the intended function and / or visual appearance.

[0077] Figure 4 An embodiment of a shoe including a modular rim system is shown. This modular rim system includes a support frame 410 designed to receive and removably hold functional components. The support frame 410 is integrated into the sole of the shoe, providing structural support and facilitating the attachment of various components. The support frame 410 includes a profile substantially corresponding to the sole profile, ensuring seamless integration with the shoe design. The frame is depicted as having a flat, elongated structure arranged to follow the sole profile. This structure forms a U-shape opening at the forefoot of the sole, allowing flexibility and adaptability in attaching functional components. This embodiment features a connector 430 adapted to attach functional components to the support frame 410. Thus, the connector 430 serves as an attachment means, configured to facilitate the attachment of functional components to the support frame 410. The functional components in this embodiment include inverted V-shaped support structures 412. These structures are designed to provide additional support and stability to the shoe. The support structure 412 is generally rigid but flexes to allow for natural foot movement. It is located on the sole and upper of the shoe and can be used as a heel cage. The support structure 412 can have different colors depending on the level of support it provides. For example, red can indicate medium support, and black can indicate a more rigid support structure 412 that provides the highest support. Due to this invention, the support structure 412 can be replaced by the wearer according to the required support.

[0078] Figure 4The image also shows two attachment saddles 414 adapted to rest on top of the upper or heel area of ​​the shoe or at the ankle. The attachment saddle 414 in this example has mushroom-shaped protrusions adapted to engage with the tip of a V-shaped support structure 412 to releasably secure the support structure 412 to the upper or shoe. The attachment saddle 414 can be a foam element and / or a soft attachment point that is comfortable for the user. The attachment saddle 414 can be activated only when the foot is unstable and requires support, such as when the ankle is at risk of twisting due to instability.

[0079] Similarly, fine-tuning can be provided for the support structure 412, for example, by making the attachment saddle 414 slidable, and / or by providing multiple closely adjacent attachment points for the support structure 412 near its tip. Each attachment point will be adapted to engage with one attachment saddle 414, and depending on which attachment point is selected, the angle of the V-shape and / or the pretension of the support structure 412 can be adjusted. In this way, the support structure 412 can adapt to specific locations of the wearer's ankle bones, medial and lateral malleoli, and / or Achilles tendon, which are often different between individuals. This ability to adjust the angle between the arms and the position of the tips will help to adjust the overall positioning of this functional component, thereby allowing the shoe to better fit the individual user.

[0080] Fine-tuning is also possible when there are multiple closely adjacent joints 430 (not shown) on the support frame 410. In this case, the user can select which of the multiple closely adjacent joints 430 on the support frame 410 to attach to each arm of the V-shaped support structure 412. This allows for changing the angle and / or pretension of the V-shaped support structure and will give the user more control over customizing the fit of the V-shaped support structure 412 on the shoe.

[0081] Figure 5A and Figure 5B A modular rim system integrated into the sole of a shoe is illustrated. The system includes a support frame 510 designed to receive and removably hold functional components. The support frame 510 shows a plurality of joints 530 that facilitate the attachment of various functional components to the frame. These joints 530 are evenly spaced along the support frame 510, ensuring a balanced distribution of components around the frame. However, in other embodiments, the joints may be positioned more densely in some areas and more sparsely in others, depending on the functionality.

[0082] The figure also shows a functional component 512, which is a rigid or semi-rigid body with a generally elongated shape. Component 512 is adapted to conform to the profile of the support frame 510 and features a convex, curved edge facing the ground. This convex, curved edge is configured to facilitate a natural rolling motion during the wearer's stride when the functional component 512 is attached to the support frame 510. The tapered edges at both ends of the body 512 further enhance the rolling motion, providing a smooth transition in the wearer's gait cycle. When the wearer steps down, the downward vertical movement of the foot is smoothly transitioned into a forward roll. Thus, the functional component 512 acts as a rocker element. Depending on the desired amount of rocker effect, the user can select from various shapes of rocker functional components 512—from extreme curvature to minimal curvature. Although Figure 5A and Figure 5B A forefoot rocker functional component 512 is shown, but other embodiments may alternatively or additionally include a heel rocker element. Similarly, the rocker element may extend from the toes to the heel, along the entire medial side (inner side of the foot) and / or lateral side (outer side of the foot) of the sole, i.e., in the forefoot and hindfoot regions.

[0083] Figure 6 A modular frame system integrated into the sole of the shoe is shown. A support frame 610 serves as the base structure, to which other components are attached. The support frame 610 is characterized by its elongated and contoured design, following the curvature of the sole to ensure stability and support. Attached to the support frame 610 are joints 630, which facilitate the connection of additional components. These joints are strategically positioned along the frame, allowing for modularity and customization in the shoe's design. Joints 630 are designed to accommodate various fastening mechanisms, enabling components to be securely attached while allowing for easy removal and replacement. The figure also depicts elastic tensioning elements 612, which are connected to the support frame 610. These tensioning elements 612 are elongated structures extending along the body portion of the frame. They are designed to transfer forces between the front and rear sections of the support frame, thereby enhancing the shoe's dynamic behavior during movement. Tensioning elements 612 contribute to forefoot rocker and overall rocker behavior, promoting natural rolling motion during stride.

[0084] The tensioning elements 612 can also be interconnected to form a loop passing through the frame. The channel passing through the frame can be a channel—transverse to the longitudinal direction of the shoe—or a tubular structure, such as… Figure 6As indicated by reference numeral 614 in the accompanying drawings. The tensioning elements 612 on the proximal and lateral sides may also be separate or spaced apart from each other, and are directly attached to the support frame (in this case, a plate) on their corresponding sides in the forefoot and midfoot sections. The tensioning elements 612 pre-flex the support frame, thereby providing a propulsive or spring-like effect when the frame with this functional component is worn in the shoe by the user.

[0085] Figure 7 A shoe 700 is shown, incorporating a modular rim system designed to enhance the functionality and adaptability of footwear. The shoe includes a support frame 710 integrated into a sole 720. The support frame 710 is designed to receive and securely hold various functional components, allowing for customization and optimization according to user preferences or specific activities. The sole 720 is depicted with a profile that at least partially corresponds to the shape of the support frame 710, ensuring seamless integration between these components. In this embodiment, a first resilient tensioning element 712a is positioned along the body-side portion of the support frame 710. Similarly, resilient tensioning elements 712a or additional tensioning elements 712a may also be positioned along the proximal portion of the support frame 710, for example, to balance tension. The element 712a is characterized by an elongated form—having attachment points at opposite ends, particularly at attachment points 731 and 732. The tensioning element 712a is configured to attach to both the front portion 731 and the rear portion 732 of the support frame 710. This attachment allows the tensioning element 712a to transfer force between the front and rear portions of the support frame 710, thereby enhancing the forefoot rocker and contributing to the overall rocker behavior of the shoe 700.

[0086] Figure 7 The embodiment also includes a second resilient tensioning element 712b positioned along the body-side portion of the support frame 710. Similarly, the resilient tensioning element 712b, or an additional tensioning element 712b, may also be positioned along the proximal portion of the support frame 710, for example, to balance tension. The element 712b is characterized by its elongated form—having attachment points at opposite ends, particularly at attachment points 731 and 730. The tensioning element 712b is configured to attach to both the front portion 731 and the midfoot portion 730 of the support frame 710. This attachment allows the tensioning element 712b to transmit force between the front and midfoot portions of the support frame 710, thereby enhancing the forefoot rocker and contributing to the overall rocker behavior of the shoe 700.

[0087] Tensioning elements 712a and 712b can also be formed as a single tensioning element, which is connected to the support frame 710 at attachment points 730 and 732 and passes through attachment point 731 in a loop. For this purpose, attachment point 731 can be formed as a loop or hook. Thus, attachment point 731 can slide along the tensioning element—depending on the force acting on the support frame 710.

[0088] Furthermore, if the tensioning element is present on the proximal and lateral sides of the shoe, it can be formed as a single tensioning element—forming a ring. In this case, the tensioning element can be guided through a channel or tube in the plate-like support frame 710. Thus, the channel or tube can form attachment points 730 and / or 732.

[0089] Figures 8 to 14D Different types of fastening mechanisms, attachment means, or joints are shown for attaching one or more functional components to the support frame of the present invention as described herein.

[0090] Figure 8 A torsion locking mechanism 800 is shown, comprising a rotatable element 835 having a specific shape. A recess 830 with a corresponding negative shape is formed in a support frame 810. The rotatable element 835 may be disposed on a functional component to be attached to the support frame 810. For example, a portion of the rotatable element 835 may pass through an opening in the functional component. The rotatable element (and the functional component therewith) is secured to the support frame 810 by inserting the rotatable element 835 into the recess 830 and rotating it 90° (a quarter turn). This provides a simple yet secure attachment of the functional component to the support frame 810.

[0091] Figure 9 A magnetic attachment means 900 is illustrated. In this example, magnets 930 are constructed at discrete locations within a support frame 910. Alternatively, the entire frame can be magnetized using polymer magnet technology. Magnets 930 can be standard round or square magnets, overlaid and injected into a plastic frame or attached after molding the support frame 910. In the case of polymer magnets, magnetic material is incorporated into a polymer, which is then injected and magnetized. Typically, magnetic attachment means provide lightweight attachment while being easy to handle.

[0092] Figure 10A and Figure 10B A sliding channel attachment means 1000 is shown, wherein Figure 10A It is a cross-sectional view. Figure 10B This is a perspective view. In this example, the frame portion 1005 of the support frame 1010 has a cover closure 1030 that allows the attached anchor 1040 to slide forward and backward and bear loads, such as functional components. Discrete points may exist (where the attached anchor gets stuck), or the frame portion 1005 and the cover closure 1030 may be continuous. The sliding channel attachment means 1000 typically allows for moderate-strength attachments.

[0093] Figure 11A , 11BFigure 11C shows an attachment means 1100 in the form of a spring retaining recess 1130, which is formed on a support frame 1110. Figure 11A and 11B A side view is shown, while Figure 11C A top view is shown. The spring-retaining recess 1130 includes a spring 1132 and a recess 1134. An attachment anchor 1140 can be fitted into the recess 1134 and held in place by the spring 1132. To release the attachment anchor 1140, the spring 1132 is pushed down and the attachment anchor 1140 is pulled out of the recess 1134. The attachment anchor 1140 can, for example, be part of a functional component—as described herein—to be attached to the support frame 1110. The spring-retaining recess attachment means 1100 provides a secure attachment. Figure 12 A hook-and-loop attachment means 1200 is shown. A hook-type attachment 1230 is glued, for example, to a support frame 1210, and can be attached to a corresponding loop counterpart in a functional component or to a textile piece 1240 that is part of or forms part of a functional component. This attachment means is simple but suitable for attachment to textiles and provides a moderately strong attachment.

[0094] Figure 13A and 13B A cord attachment means 1300 is shown. In this example, one or more hooks 1330 protrude from a support frame 1310. A tension cord system 1340, which may be formed or may be part of a functional component, may be wound around the one or more hooks 1330. Figure 13A The hooks 1330 in the example are open, but they can also be closed. This type of attachment allows for moderate-strength attachments.

[0095] Figure 14A -D illustrates a bending rod attachment means 1400. In this example, a recess 1430 is formed in a support frame 1410. A flexible and resilient rod 1440 can be adapted to the recess 1430 when properly bent, such as... Figure 14B As shown. Rod 1440 can help support the bending stiffness of frame 1410, and thus contribute to... Figure 14C The support frame 1410 shown is integrated into the flexural stiffness of the sole 1420. Therefore, the rod 1440 can form a functional component. Alternatively, or additionally, the rod 1440 can form a carrier for a functional component, such as... Figure 14D The shoe upper component 1445 is shown. Figure 14A The attachment method type shown in -D by the bending rod provides a medium-strength attachment.
