Description

Technical Field

[0001] This utility model relates to the field of footwear technology, specifically to a shoe Background Technology

[0002] In various sports scenarios, the foot endures complex multi-directional forces during high-intensity movements, making dynamic fit and adaptive support of footwear a core requirement. Whether in high-intensity competitive sports or everyday active activities, the stability and constraint of the foot, especially the heel and ankle, directly affect athletic performance and safety. Currently, foot-fitting designs have significant limitations. Their support structures are not sufficiently adapted to the dynamic shape of the foot during movement, making it difficult to adjust to real-time deformations of the foot. They can only provide basic support for low-intensity activities or static states. In scenarios requiring frequent force exertion or rapid changes of direction, this design can easily lead to gaps between the shoe and the foot, increasing the risk of lateral slippage. This not only affects the stability of movements and the efficiency of force transmission but may also cause sports injuries. Furthermore, it is difficult to balance support and comfort, failing to meet the functional requirements of diverse sports equipment. Utility Model Content

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art, and to provide a combination of rigid support and flexible adjustment through a sole wrapping frame and an upper strap system, which overcomes static rigid constraints, achieves precise constraint on lateral ankle sliding, and significantly reduces the risk of sports injuries.

[0004] To achieve the above objectives, the present invention and its preferred embodiments adopt the following technical solutions, but the embodiments are not limited to the following solutions:

[0005] The first technical solution relates to a shoe, comprising: a sole including a sole body, a rear fixing piece and at least two side fixing pieces disposed on the sole body; the rear fixing piece extends upward from the rear end of the sole body, and at least two side fixing pieces are symmetrically arranged on both sides of the sole width direction, and each side fixing piece extends upward and backward from the arch area of ​​the sole body and connects to the upper end of the rear fixing piece to jointly form a wrapping frame; and an upper including an upper body, a strap, a fastener, and a guide; the upper body is attached to the sole; a first end of the strap is fixed to the outer side of the upper body; the guide is fixed to the inner side of the upper body; the fastener is fixed to the outer side of the upper body and adjacent to the front end of the side fixing piece located on the outer side of the sole; in the length direction of the sole, the guide is located between the first end of the strap and the fastener; the strap extends from its first end across the upper body and passes through the guide before wrapping back to be detachably connected to the fastener.

[0006] The second technical solution is based on the first technical solution, wherein the bottom body is provided with a forefoot part, an arch part and a heel part connected to the rear fixing piece from front to back, and the two side fixing pieces are symmetrically arranged on both sides of the width direction of the arch part and extend upward and backward and are connected to the upper end of the rear fixing piece extending upward from the heel part.

[0007] The third technical solution is based on the second technical solution, wherein the two side fixing pieces are sheet-like structures; the first segment of the two side fixing pieces, which is connected to the arch of the foot and extends backward, protrudes upward and bends, while the second segment, which is connected to the rear fixing piece, is recessed downward and bends; the connection between the first segment and the second segment is smooth, and the width of the first segment along the shoe height direction is greater than the width of the second segment.

[0008] The fourth technical solution is based on the second technical solution, wherein the two side fixing pieces are made of thermoplastic polyurethane elastomer material with a hardness greater than 90A and are integrally formed with the arch of the foot through an injection molding process.

[0009] The fifth technical solution is based on the second technical solution, wherein the sole further includes a midsole, the midsole is fixed to the upper surface of the sole body, and has an arch section and a heel section corresponding to the arch part and heel part of the sole body respectively, and the thickness of the heel section is greater than the thickness of the arch section.

[0010] The sixth technical solution is based on the fifth technical solution, wherein the thickness of the arch segment is 0.2-0.5 times the thickness of the arch portion, and gradually increases in thickness as it extends backward until the thickness of the heel segment is 0.7-1 times the thickness of the heel portion.

[0011] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0012] In the first technical solution, the sole includes a sole body, a rear fixing plate, and at least two side fixing plates. The rear fixing plate extends upward from the rear end of the sole body, and the two side fixing plates are symmetrically arranged on both sides of the sole width direction. Each side fixing plate extends upward from the arch area of ​​the sole body and connects to the upper end of the rear fixing plate, together forming a wrapping frame that provides three-dimensional surround support for the ankle, heel, and arch. Compared with the prior art, this structure overcomes the static rigidity constraint, allowing its support structure to adapt to the dynamic shape of the foot during movement and adjust to the real-time deformation of the foot, thus achieving better stable wrapping of the foot and preventing lateral slippage during high-intensity exercise.

[0013] The design of the side fixation plate extending from the arch area specifically strengthens the arch support, preventing fatigue or pain caused by excessive arch collapse during exercise, and is especially suitable for sports scenarios that require frequent exertion.

[0014] The upper consists of the upper body, straps, retaining plate, and guides. The straps start from the outside, cross the upper body, pass through the inner guide, and wrap around to connect to the outer retaining plate, forming a ring-shaped tightening structure for the instep. The detachable connection design of the straps allows users to flexibly adjust the tightness according to their own foot shape, avoiding the problems of traditional fixed uppers being too tight and oppressive or too loose and wobbly, while ensuring a close fit between the foot and the upper, reducing the relative displacement between the foot and the shoe during exercise. The guides are located between the first end of the straps and the retaining plate, which can guide the direction of the strap force to better conform to the curvature of the instep, so that the tightening force is evenly distributed, avoiding local pressure and improving the comfort of long-term exercise.

[0015] In summary, this technical solution combines rigid support with flexible adjustment through the sole wrapping frame and upper strap system, achieving synergistic optimization in terms of stable support, wrapping fit, and force transmission. It overcomes static rigid constraints, achieves precise restraint on lateral ankle sliding, and significantly reduces the risk of sports injuries.

[0016] In the second technical solution, the sole body is composed of a forefoot section, an arch section, and a heel section connected to the rear fixing plate, arranged sequentially from front to back. Two symmetrical side fixing plates extend from the arch section to both sides, connecting upwards and backwards to the upper end of the rear fixing plate in the heel section, forming a complete support frame that wraps around the arch, heel, and ankle. This comprehensively resists lateral forces during exercise, effectively restricts lateral slippage of the ankle relative to the sole, and provides stable three-dimensional constraint for the foot, adapting to the needs of frequent changes of direction and force exertion during high-intensity sports. Compared to existing technologies, the wrapping and support are no longer concentrated in a localized area. This improves sports safety, reduces the risk of injury, and enhances comfort during prolonged exercise.

[0017] In the third technical solution, the first section of the side fixation plate bulges upwards, precisely conforming to the arc-shaped contours of the arch of the foot, while the second section curves downwards to fit the shape of the ankle. The smooth transition between the two sections allows the entire side fixation plate to naturally conform to the physiological curve of the foot from the midfoot to the ankle, improving the fit and achieving continuous wrapping from the arch to the ankle, thus enhancing stability during exercise. The wider first section provides more support area and lateral torsional strength for the arch area, effectively resisting excessive deformation of the arch during exercise. The narrower second section reduces restriction on ankle movement, ensuring lateral stability while allowing sufficient space for ankle flexion, extension, and rotation, balancing support and flexibility, forming a cushioned arc structure that distributes lateral forces transmitted from the foot to a larger area. The smooth transition at the joint avoids stress concentration, enhancing the overall structural strength and durability of the side fixation plate, extending its service life, further strengthening the synergistic effect of the overall support frame of the sole, and improving the stability and restraint effect on the foot.

[0018] In the fourth technical solution, to ensure high-strength support performance, a thermoplastic polyurethane elastomer material with a hardness greater than 90A is used. This material has excellent rigidity and deformation resistance, providing strong structural support for the side fixation plate. It can effectively resist the lateral forces generated by the foot during exercise, ensuring the fit and stable constraint of the ankle and arch, and meeting the support strength requirements of high-intensity sports. The side fixation plate and the arch area of ​​the sole body are integrally molded through injection molding, forming a seamless and firm bond between the two. This avoids problems such as loosening and detachment that may occur with traditional assembly methods, ensuring the stable transmission of support force from the side fixation plate to the arch area, and improving the durability and service life of the overall structure.

[0019] In the fifth technical solution, the heel section of the midsole is thicker than the arch section. As the main load-bearing area for landing impact during exercise, the thicker heel section can effectively absorb impact energy through material deformation, reducing the impact of ground reaction force on the heel and lower limb joints; while the thinner arch section can ensure the structural flexibility of the arch area.

[0034] In the claims, description and accompanying drawings of this utility model, the terms "comprising", "having", and variations thereof are used to mean "including but not limited to".

[0035] In this embodiment, for the sake of referring to the accompanying drawings and for ease of explanation, the L direction is defined as the front-to-back direction of shoe 1; the Y direction is defined as the length direction of shoe 1.

[0036] See Figure 1 , Figure 1 An exploded view of shoe 1 in an embodiment is shown. Figure 1 As shown, shoe 1 comprises a sole and an upper, which are securely connected. Specifically, the sole and upper are fixedly connected by adhesive bonding and stitching reinforcement, effectively preventing relative displacement during exercise.

[0037] See Figure 2 , Figure 2 An exploded view of the base 5 body 4 in the embodiment is shown. (See figure) Figure 2 As shown, the sole of shoe 1 includes a sole body 4 and a midsole 5. The sole body 4 is divided into a forefoot section 8, an arch section 9, and a heel section from front to back. These sections work together to form the basic support frame of the sole of shoe 1, and are equipped with a rear fixing plate 6 and at least two side fixing plates 7. The side fixing plates 7 extend upward from the rear end of the heel section to conform to the physiological contour of the back of the heel, providing longitudinal stability support for the heel. The side fixing plates 7 are made of materials with a hardness of 95A. The thermoplastic polyurethane elastomer material is integrally molded with the arch support 9 through injection molding to ensure connection strength and structural stability. The two fixing plates 7 are symmetrically distributed on both sides of the arch support 9 in the width direction. The overall structure is a sheet structure, specifically divided into two sections. The first section is located at the connection with the arch support 9, protruding upward and curved, with the curvature matching the outer side of the arch. The width along the height direction of the shoe 1 is greater than the second section, providing sufficient lateral support area for the arch and effectively resisting excessive deformation of the arch during exercise. The second section is located at the connection with the rear fixing plate 6, concave downward and curved, adapting to the concave shape of both sides of the ankle. The connection between the two sections adopts a smooth transition arc to improve the durability of the overall structure. The narrowing design reduces the restriction on ankle movement. The two fixing plates 7 extend upward and backward from the arch support 9 and finally connect to the upper end of the rear fixing plate 6, together forming a wrapping frame around the arch, heel and ankle to achieve three-dimensional support. In this embodiment, there are two fixing plates.

[0038] See Figure 3 , Figure 3 A rear view of the sole of shoe 1 in an embodiment is shown. (See example...) Figure 2 and Figure 3 As shown, the midsole 5 is made of EVA material and is fixed to the upper surface of the sole body 4, together forming the complete sole of the shoe 1. The midsole 5 includes an arch section 11 corresponding to the arch part 9 and a heel section 12 corresponding to the heel part. The thickness of the arch section 11 is 0.2-0.5 times the thickness of the arch part 9, ensuring the structural flexibility of the arch area. The thickness gradually increases as it extends backward, reaching 0.7-1 times the thickness of the heel part at the heel section 12. This thickened design enhances the cushioning and shock absorption effect when the heel lands. Specifically, the midsole 5 and the upper surface of the sole body 4 are bonded together by a molding process to ensure a stable connection between the two and prevent relative displacement during movement.

[0039] See Figure 4 , Figure 4 A first schematic diagram of shoe 1 in an embodiment is shown. (See attached diagram.) Figure 4 As shown, the upper of shoe 1 is fixedly connected to the sole of shoe 1, and includes an upper body 13, a strap 14, a fastener 15, and a guide 16. In this embodiment, the upper body 13 is provided with a toe area, an instep area 18, a collar area 19, and a heel counter area 20 from front to back. The toe area, instep area 18, and collar area 19 are made of woven mesh fabric, which has excellent breathability and elasticity, can closely fit the contour of the foot, and adapt to the dynamic deformation of the foot to stretch, thereby improving wearing comfort. The heel counter area 20 is made of a composite of PP film, imitation leather-like artificial microfiber, and woven mesh fabric, which takes into account both toughness and elastic recovery, and together with the wrapping frame of the sole of shoe 1, enhances the stable wrapping of the heel and ankle.

[0040] See Figure 5 and Figure 6 , Figure 5 A second schematic diagram of shoe 1 in the embodiment is shown; Figure 6 A third schematic diagram of shoe 1 in an embodiment is shown. (See attached diagram.) Figure 5 and Figure 6 As shown, the first end of the strap 14 is fixed to the outside of the upper body 13, and the guide 16 is fixed to the inside of the upper body 13. Located between the first end of the strap 14 and the fixing member 15 along the length of the shoe sole, the guide 16 guides the direction of force on the strap 14, ensuring even distribution of the tightening force on the instep. The fixing member 15 is fixed to the outside of the upper body 13, adjacent to the front end of the side fixing piece 7. The strap 14 starts from the first end, crosses the upper body 13, passes through the guide 16, and then wraps back. It can be detachably connected to the fixing member 15 via Velcro or other means, allowing the user to adjust the tightness according to their foot shape. In this embodiment, the strap 14 is made of a composite of microfiber leather and PP film, combining elasticity and structural stability.

[0041] like Figure 5 and Figure 6 As shown, specifically, starting from the arch 9, the rear fixing plate 6 extends upward along the back of the heel, and the two side fixing plates 7 bend upward and backward from both sides of the arch, ultimately forming a closed annular support space in the middle of the ankle. The inner contour and the physiological curve of the middle and rear of the foot cover the core stress areas of the arch, heel, and ankle, forming a basic framework for dynamic rigid constraint. The strap 14 spans the instep area 18, with its fixing end and fixing member 15 located on both sides of the front end of the wrapping frame, and the guide member 16 at the corresponding position on the inner side of the frame, forming a transverse tightening band that connects with the front end of the frame. This structure ensures that the tightening range of the strap 14 precisely covers the instep area 18 that is not directly constrained by the frame, forming a continuous wrapping space with the middle and rear support of the frame, avoiding support blind spots.

[0042] See Figure 7 , Figure 7 A rear view of shoe 1 in an embodiment is shown. (See example...) Figure 7 As shown, after the sole of shoe 1 is connected to the upper of shoe 1, the two side fixing plates 7 are connected to the rear fixing plate 6 to form a complete shoe 1. When the user is exercising, the thermoplastic polyurethane elastomer material with a stiffness of 95A provides strong anti-torsional performance to resist excessive pronation or supination of the ankle; at this time, the strap 14 is moderately stretched due to the composite characteristics of microfiber leather and PP film, which releases some pressure with the instantaneous expansion of the foot, and maintains a close fit through elastic recovery force to prevent gaps between the foot and the frame.

[0043] The shoe 1's sole frame and the shoe 1's upper strap system work together to provide stable lateral restraint. The heel support plate 6 and the resulting rigid support structure provide stable lateral restraint. The differentiated thickness design of the midsole 5 balances cushioning and flexibility needs. The breathable fabric of the shoe 1's upper and the adjustable straps 14 ensure the comfort and adaptability of dynamic wrapping. This allows the entire shoe 1 to meet the needs of high-intensity sports for stable foot support, and to adapt to different foot shapes through flexible adjustment, effectively reducing the risk of sports injuries. When the forefoot exerts force, the arch will collapse slightly. The raised bending structure of the first section of the side support plate 7 can elastically deform with the arch deformation. The straps 14, through the steering action of the guide 16, automatically distribute the tension to the inside of the arch, working with the frame to prevent excessive arch collapse. The straps 14 maintain basic tightening force, keeping the foot and frame in initial contact. The frame bears the main support force through its own rigidity, reducing fatigue and loosening caused by long-term stress on the straps 14.

[0044] In summary, this application balances support, adaptability, and safety through the synergistic mechanism of rigid frame shaping and strap 14, providing comprehensive dynamic protection for the foot.

[0045] In this embodiment, the sole of the shoe 1 includes a sole body 4, a rear fixing plate 6 and at least two side fixing plates 7 on the sole body 4. The rear fixing plate 6 extends upward from the rear end of the sole body 4. The two side fixing plates 7 are symmetrically arranged on both sides of the sole width direction. Each side fixing plate 7 extends upward from the arch area of ​​the sole body 4 and connects to the upper end of the rear fixing plate 6, together forming a wrapping frame to provide three-dimensional surround support for the ankle, heel, and arch. Compared with the prior art, this structure overcomes the static rigidity constraint, allowing its support structure to adapt to the dynamic shape of the foot during movement and adjust to the real-time deformation of the foot, thus achieving better stable wrapping of the foot and preventing lateral slippage during high-intensity exercise. The design of the side fixing plates 7 extending from the arch area specifically strengthens the arch support, avoiding fatigue or pain caused by excessive arch collapse during exercise, and is especially suitable for sports scenarios that require frequent force exertion. The upper of the shoe includes an upper body 13, a strap 14, a fixing plate, and a guide 16. The strap 14 forms a ring-shaped tightening structure for the instep by starting from the outside, crossing the upper body 13, passing through the inner guide 16, and wrapping around to connect to the outer fixing plate 15. The detachable connection design of the strap 14 allows users to flexibly adjust the tightness according to their own foot shape, which avoids the problems of traditional fixed uppers being too tight and pressing or too loose and wobbling, and ensures a close fit between the foot and the upper of the shoe, reducing the relative displacement between the foot and the shoe during exercise. The guide 16 is located between the first end of the strap 14 and the fixing plate 15, which can guide the direction of force of the strap 14 to better fit the curvature of the instep, so that the tightening force is evenly distributed, avoiding local pressure and improving the comfort of long-term exercise. In summary, this technical solution combines rigid support with flexible adjustment through the sole wrapping frame and upper strap system of the shoe 1. It achieves synergistic optimization in terms of stable support, wrapping fit, and force transmission, overcomes static rigid constraints, achieves precise constraint on lateral ankle sliding, and significantly reduces the risk of sports injuries.

[0046] In this embodiment, the sole body 4 is provided with a forefoot portion 8, an arch portion 9, and a heel portion connected to the rear fixing plate 6 from front to back. Two symmetrical side fixing plates 7 extend from the arch portion 9 to both sides, connecting upwards and backwards to the upper end of the rear fixing plate 6 of the heel portion, forming a complete support frame that wraps around the arch, heel, and ankle. This frame can comprehensively resist lateral forces during exercise, effectively limit the lateral sliding of the ankle relative to the sole of the shoe 1, and provide stable three-dimensional constraints for the foot, adapting to the needs of frequent changes of direction and force exertion during high-intensity exercise. Compared with existing technologies, the wrapping and support are no longer concentrated in a local area. This improves sports safety, reduces the risk of injury, and enhances comfort during long-term exercise.

[0047] In this embodiment, the first section of the side fixation piece 7 is convex and curved upwards, which can precisely fit the arc-shaped contours of both sides of the arch of the foot, while the second section is concave and curved downwards to adapt to the shape of both sides of the ankle. The smooth transition between the two sections allows the entire side fixation piece 7 to naturally conform to the physiological curve of the foot from the midfoot to the ankle, improving the fit with the foot and achieving continuous wrapping from the arch to the ankle, thus enhancing stability during exercise. The first section is wider, providing more support area and lateral torsional strength for the arch area, effectively resisting excessive deformation of the arch during exercise. The second section is narrower, which reduces the restriction on ankle movement. While ensuring lateral stability of the ankle, it leaves enough space for ankle flexion, extension, rotation, and other movements, balancing support and flexibility, forming a buffer arc structure that disperses the lateral force transmitted by the foot to a larger area. The smooth transition at the joint avoids stress concentration, enhances the overall structural strength and durability of the side fixation piece 7, extends its service life, further strengthens the synergistic effect of the overall support frame of the shoe sole 1, and improves the stability constraint effect on the foot.

[0048] In this embodiment, to ensure high-strength support performance, a thermoplastic polyurethane elastomer material with a hardness greater than 90A is used. This material has excellent rigidity and resistance to deformation, providing strong structural support for the side fixation plate 7. It can effectively resist the lateral forces generated by the foot during exercise, ensuring the fit and stable constraint of the ankle and arch, and meeting the support strength requirements of high-intensity sports. The side fixation plate 7 and the arch area of ​​the sole body 4 are integrally molded through injection molding, forming a seamless and firm bond between the two. This avoids problems such as loosening and detachment that may occur in traditional assembly methods, ensuring the stable transmission of support force from the side fixation plate 7 to the arch area, and improving the durability and service life of the overall structure.

[0049] In this embodiment, the heel section 12 of the midsole 5 is thicker than the arch section 11. As the main load-bearing area for landing impact during exercise, the thicker heel section 12 can effectively absorb impact energy through material deformation, reducing the impact of ground reaction force on the heel and lower limb joints; while the thinner arch section 11 can ensure the structural flexibility of the arch area.

Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
