Description

Technical Field

[0001] This utility model relates to the field of footwear technology, and in particular to a running shoe sole and a running shoe. Background Technology

[0002] The main function of running shoe soles is to provide effective cushioning, energy return, stable support, and traction for the feet. During running, each time the foot strikes the ground, it generates a significant impact force. If this impact force is not effectively absorbed, it can accumulate over time and easily lead to sports injuries to the feet, knees, and even the lower back.

[0003] Most running shoe soles in current technology employ a multi-layered composite structure. The midsole, which is closest to the foot, provides cushioning and shock absorption, while the outsole provides abrasion resistance and slip resistance. However, the relatively hard midsole materials offer poor cushioning and shock absorption, resulting in greater impact and failing to ensure athlete comfort. Furthermore, the uneven terrain leads to greater muscle load and fragmented rhythms, increasing the risk of sprains, and the lack of coordinated support makes ankle twists more likely.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 4As shown, this utility model provides a running shoe sole, comprising, from top to bottom, a cushioning plate 1, a rebound layer 2, a stabilizing layer 3, and a traction layer 4. The cushioning plate 1 is embedded in the heel of the rebound layer 2 to avoid injury to the body caused by high-intensity foot pressure during exercise. Both the rebound layer 2 and the stabilizing layer 3 are made of elastic material to provide good cushioning and shock absorption. The traction layer 4 has a through hole 41 located at the heel. A support part 31 protrudes from the side of the stabilizing layer 3 facing the traction layer 4, passing through the through hole 41 and abutting against the ground. By setting the through hole 41, the weight of the traction layer 4 can be reduced, making the sole lighter overall. At the same time, the setting of the support part 31 also provides cushioning and shock absorption, thereby ensuring the comfort of the athlete.

[0033] Specifically, in this embodiment, the shock absorber 1 is an ACF cartilage high-strength shock absorber 1, with an energy absorption efficiency of over 90%, reaching up to 97.1%. It possesses excellent fatigue resistance, exhibiting no performance degradation after 5 million compression cycles. It effectively absorbs the impact of foot strike on the joints, extending athletic lifespan. The ACF cartilage high-strength shock absorber 1 is made of a three-dimensional ultra-micro nanostructure, possessing high impact resistance, high velocity sensitivity, and vibration damping characteristics. Furthermore, it exhibits stable performance, fatigue resistance, compression resistance, and high-temperature resistance. For example, in this embodiment, the density of the shock absorber 1 is 0.38 g / cm³. 3 It has a thickness of 3mm, a hardness of 30ASKER C, a maximum compression deformation of 10%, and a tear strength of 3N / mm.

[0034] The fourth grip layer is a full-length rubber outsole designed with VIBRAM TRACTION LUG technology, which increases grip by 25%. It also uses MEGAGRIP wet-wet anti-slip rubber compound, which increases traction by 30%, providing excellent grip and anti-slip properties on both dry and wet surfaces.

[0035] Optionally, such as Figure 1 and Figure 2 As shown, the rebound layer 2 has an installation groove 21, and the damping pad 1 is embedded in the installation groove 21. The side wall of the installation groove 21 can provide a horizontal limiting effect on the damping pad 1 to prevent the damping pad 1 from undergoing excessive lateral deformation or displacement after being subjected to force, thereby ensuring the stability of landing.

[0036] Furthermore, the outer wall of the damping pad 1 is provided with at least one limiting part 11, and the side wall of the mounting groove 21 is provided with a corresponding limiting groove 211, so that the limiting part 11 can be engaged in the corresponding limiting groove 211. Through the engaging cooperation between the limiting part 11 and the limiting groove 211, the damping pad 1 can be stably set in the mounting groove 21 and always be in the preset position, thereby ensuring the stability of the motion posture and the efficiency of force transmission.

[0037] Specifically, such as Figure 1 As shown, in this embodiment, there are two limiting parts 11 and two limiting grooves 211; in other embodiments, the number of limiting parts 11 and two limiting grooves 211 can be set as needed, and no specific limitation is made here.

[0038] Optionally, continue to refer to Figure 1 and Figure 2 The rebound layer 2 features multiple flex grooves 22 spaced apart at the forefoot area. When walking or running, the forefoot (metabolous region) naturally flexes. Without these flex grooves 22, the sole might flex irregularly at any point, leading to premature fatigue of the sole material, unsightly wrinkles, or even discomfort due to pressure on the foot. The flex grooves 22 ensure that the flexing action occurs in the correct position on the sole, allowing for greater flexibility. Furthermore, the flex grooves 22 reduce the weight of the sole, improving wearing comfort.

[0039] For example, in this embodiment, four bending grooves 22 are provided on the spring layer 2; in other embodiments, the number of bending grooves 22 can be set as needed, and no specific limitation is made here.

[0040] Optionally, the stabilization layer 3 is located at the heel and forefoot, covering the entire sole area to effectively limit unnatural excessive deformation of the foot in any position and prevent sprains. It also provides continuous and even arch support, reducing pressure on the plantar fascia. Furthermore, during exercise, the heel-to-toe landing roll is smoother and more fluid, without the jerky feeling caused by localized differences in softness and hardness, resulting in a more stable and efficient running experience.

[0041] Alternatively, in other embodiments, the stabilizing layer 3 may be located only at the heel. The stabilizing layer 3 is a relatively thick and rigid part of the sole; its placement only at the heel significantly reduces the overall weight of the shoe, thereby reducing athlete fatigue. Furthermore, during walking or running, athletes typically land heel-first; the stabilizing layer 3 at the heel ensures stable support upon landing while providing ample freedom for the forefoot, resulting in a smoother and more efficient gait.

[0042] Optionally, the rebound layer 2 has a rebound rate of over 60% and a hardness of 43 to 48 degrees, preferably 45 degrees. The high rebound rate of the rebound layer 2 can solve the problem of material efficiency loss in mountain trail running, making it superior in rebound speed and energy storage efficiency, while reducing energy loss and achieving breakthroughs in speed and endurance.

[0043] The stabilizing layer 3 has a rebound rate of over 55% and a hardness of 48 to 56 degrees, preferably 52 degrees. After absorbing shock, the stabilizing layer 3 can quickly convert the shock into propulsive force to alleviate the impact of the ground on the foot. Its relatively firm hardness can shape the athlete's gait support base, ensuring dynamic stability, preventing torsion and rollover, reducing the probability of injury during exercise, and providing assistance to the athlete while providing safety protection.

[0044] Optionally, the materials for the rebound layer 2 and the stabilizing layer 3 are EVA, ETPU, or PEBA. While EVA has good abrasion resistance, it tends to lose elasticity after long-distance use. ETPU and PEBA materials are both produced using supercritical nitrogen or carbon dioxide fluid foaming technology. This technology allows the gas to completely penetrate into the material particles, forming countless extremely small, uniform, and closed bubbles after pressure relief. This microstructure also results in long service life, lightweight, high resilience, and low energy loss.

[0045] Optionally, such as Figure 3 and Figure 4 As shown, the stabilizing layer 3 has a positioning groove 32 on the side facing the gripping layer 4, such as... Figure 1 and Figure 2 As shown, a positioning protrusion 43 is provided on the side of the gripping layer 4 facing the stabilizing layer 3. The positioning protrusion 43 can abut against the positioning groove 32 to improve the stability between the stabilizing layer 3 and the gripping layer 4 and prevent misalignment and relative sliding between the two.

[0046] Optionally, the grip layer 4 has multiple anchor claws 42 protruding from the ground-facing side, with the anchor claws 42 having a thickness of 3.5mm to 4.5mm. The anchor claws 42 provide stronger grip and more effective mud removal. The multiple anchor claws 42 are spaced apart, taking into account both push-off grip and downhill braking, making it suitable for off-road mountain roads with mixed dry and wet conditions and hardened surfaces, while also meeting the speed requirements of racing.

[0047] Furthermore, such as Figure 3 and Figure 4 As shown, the sidewall of the anchor claw 42 is provided with multiple anti-slip protrusions 421. When walking across a slope, moving sideways on slippery rocks, or making sharp turns, a strong lateral force is generated between the foot and the ground. The anti-slip protrusions 421 can increase the lateral friction between the sole of the shoe and the ground, thereby reducing the risk of slipping to the outside and improving the stability and safety of the athlete.

[0048] For example, in this embodiment, the anti-slip protrusion 421 is triangular; in other embodiments, the anti-slip protrusion 421 may also be other shapes, as long as it can increase the lateral friction force, and no specific limitation is made here.

[0049] In addition, this embodiment also provides a running shoe, including the running shoe sole described above, which has all the beneficial effects of the running shoe sole described above, and will not be repeated here.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
