Description

Technical Field

[0001] This utility model belongs to the field of training shoe technology, specifically relating to a high-support foam training shoe sole. Background Technology

[0002] Training shoes, as footwear products used frequently and under heavy loads, require soles that simultaneously meet the needs of support, durability, and comfort. Existing training shoe soles generally suffer from insufficient support structure. Most soles use a single foam layer such as ordinary EVA or polyurethane, or only have simple reinforcement plates in certain areas, without designing specific support structures for key pressure areas of the foot, such as the forefoot lateral side, arch, and heel. Long-term use can easily lead to sole collapse, arch support failure, resulting in foot fatigue and even sports injuries.

[0003] To address the aforementioned issues, there is an urgent need to design a training shoe sole that combines strong support for key areas with a fit to the foot's contours, in order to meet the needs of high-intensity training scenarios. Utility Model Content

[0004] To address the aforementioned shortcomings in the existing technology, this utility model provides a high-support foam training shoe sole to solve the problems mentioned in the background technology.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A high-support foam training shoe sole includes a rubber outsole, with the outer edge of the rubber outsole extending upward to form a ring-shaped side support edge, and the middle position of the rubber outsole recessed inward to form a support base; a high-density EVA support layer and a foam support layer are sequentially arranged on the inner side of the rubber outsole from top to bottom.

[0007] The top surface of the foam support layer has a placement groove and a positioning groove adapted to the contour of the foot. The placement groove is embedded with a segmented support carbon plate, and the positioning groove is embedded with a high-rigidity supercritical support module. The segmented support carbon plate includes a forefoot support section, an arch reinforcement section and a heel support section.

[0008] The high-rigidity supercritical support module is set with a group below the heel and on the outer side of the forefoot. The top surface of the high-rigidity supercritical support module has a snap-fit ​​groove that is compatible with the segmented support carbon plate.

[0009] The front end of the forefoot support section and the rear end of the heel support section of the segmented support carbon plate are embedded in the snap-fit ​​groove, and the arch reinforcement section fits into the inner wall of the arch area of ​​the placement groove.

[0010] Furthermore, the rubber outsole has anti-slip teeth on its bottom surface, and the anti-slip teeth are integrally injection molded with the rubber outsole.

[0011] To elaborate further, the foamed support layer is made of polyurethane material.

[0012] Furthermore, the high-rigidity supercritical support module is made of supercritical material foam, which has the characteristics of being lightweight, highly resilient, and having good wear resistance.

[0013] To elaborate further, segmented support carbon fiber plates are formed by impregnating and hardening carbon fibers arranged in the same direction with resin to create carbon fiber plates. Carbon fiber plates are characterized by high rigidity, good toughness, and light weight.

[0014] Furthermore, the segmented support carbon plate is fixedly embedded inside the foamed support layer and the high-rigidity supercritical support module through positioning grooves and snap-fit ​​grooves.

[0015] To elaborate further, the high-density EVA support layer is made by foaming and pressing high-density EVA material.

[0016] Furthermore, the high-density EVA support layer is bonded to the foam support layer, the high-rigidity supercritical support module, the segmented support carbon plate, and the rubber outsole via adhesive.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] 1. Through the composite structure of "ring-shaped side support edge + segmented carbon plate + high rigidity supercritical module", the support of key areas such as forefoot, arch and heel can be effectively strengthened to prevent sole collapse and meet the support requirements of high-intensity training.

[0019] 2. The segmented support carbon plate is double-fixed by positioning grooves and snap-fit ​​grooves, and with the overall bonding of the high-density EVA support layer, the component displacement is minimal and the support function is durable and stable.

[0020] 3. The grooved placement slots of the foam support layer adapt to the foot contour, and the segmented carbon plate conforms to the foot curve, ensuring strong support while improving wearing comfort and not affecting the flexibility of movement during training. Attached Figure Description

[0029] Example 1:

[0030] like Figure 1-3 As shown, the present invention provides a high-support foam training shoe sole, specifically comprising a rubber outsole 1, a high-density EVA support layer 5, a foam support layer 2, a segmented support carbon plate 4, and a high-rigidity supercritical support module 3.

[0031] In this embodiment, the rubber outsole 1 serves as the outermost layer of the sole, with its outer edge extending upward to form a ring-shaped side support edge, which can limit the lateral deformation of the sole; the middle position is recessed inward to form a support base, providing a stable installation foundation for the upper structure; the bottom surface is integrally injection molded with anti-slip teeth 11, which improves the friction between the sole and the ground and ensures anti-slip stability during training.

[0032] In this embodiment, a high-density EVA support layer 5 and a foamed support layer 2 are sequentially arranged from top to bottom on the inner side of the rubber outsole 1.

[0033] In this embodiment, the high-density EVA support layer 5 is made of high-density EVA material through foaming and pressing, and has high compressive strength. As the bottom support base, it can resist the longitudinal deformation of the entire shoe sole.

[0034] In this embodiment, the foamed support layer 2 is made of polyurethane material, and the top surface is provided with a groove-type placement slot 22 that adapts to the contour of an adult foot, so as to ensure that the subsequent support components can fit the foot curve and avoid support misalignment.

[0035] In this embodiment, a segmented support carbon plate 4 and two sets of high-rigidity supercritical support modules 3 are embedded inside the placement groove 22. The segmented support carbon plate 4 is made of carbon fibers arranged in the same direction and hardened by resin impregnation. It is divided into a forefoot support section 41, an arch reinforcement section 42 and a heel support section 43, which are adapted to the three key areas of the foot: forefoot, arch and heel. It utilizes the characteristics of carbon fiber of "high rigidity, good toughness and light weight" to achieve targeted support.

[0036] In this embodiment, the high-rigidity supercritical support module 3 is made of supercritical material foam, which has the characteristics of being lightweight, highly resilient, and wear-resistant. One set is set for each of the high-stress areas below the heel and on the outer side of the forefoot. The top surface of the module has a snap-fit ​​groove 31, which is adapted to the heel support section 43 of the segmented support carbon plate 4.

[0037] In this embodiment, the forefoot support section 41 is embedded in the positioning groove 21 on the bottom surface of the placement groove 22, the heel support section 43 is snapped into the snap-fit ​​groove 31 of the high-rigidity supercritical support module 3, and the arch reinforcement section 42 is attached to the inner wall of the arch area of ​​the placement groove 22; at the same time, the high-density EVA support layer 5 is bonded to the foam support layer 2, the high-rigidity supercritical support module 3, the segmented support carbon plate 4 and the rubber outsole 1 respectively by adhesive to form an overall support system and avoid component displacement.

[0038] The working principle of this utility model is as follows: The rubber outsole uses a ring-shaped side support edge to resist lateral deformation, the support base ensures the alignment of components, and the anti-slip teeth initially disperse the force, forming basic protection; the high-density EVA support layer bears longitudinal pressure to prevent collapse, and the polyurethane foam support layer uses a placement groove adapted to the foot to ensure the support components fit, forming layered force bearing; the segmented support carbon plate forefoot anti-bending, the arch thickened and reinforced, the heel collaboratively disperses force and the high-rigidity supercritical support module heel cushioning, and the forefoot outer side reinforcement provides precise support for key areas, achieving core force dispersion; finally, through the carbon plate's "positioning groove + snap-fit ​​groove" double limiting and the overall bonding of the high-density EVA support layer with each component, it is ensured that all structures are free from displacement and share the force, ultimately achieving the goal of long-term stable support and no obvious deformation under high-intensity training scenarios.
