Description

Technical Field

[0001] The utility model relates to the technical field of shoes, in particular to a sole and a running shoe with the sole. Background Art

[0002] When running, different runners adopt different running styles, which can usually be divided into three types, namely heel-landing running, forefoot-landing running and full-palm-landing running. Among them, heel-landing running refers to the landing style and running method in which the heel section touches the ground first when the foot lands to bear the body weight. This running style is the most common and is also the landing style that most runners are accustomed to. Forefoot-landing running refers to the landing style and running method in which the ball of the foot (i.e. the muscle under the big toe) touches the ground and bears the body weight when the foot lands. There are relatively few runners who are accustomed to this running style. Full-palm-landing running is relatively special. Since the arch of the human foot is hollow and cannot support body weight, when the full palm lands, the forefoot and heel actually touch the ground at the same time and bear the body weight. This landing style is sporadic and difficult to replicate step by step. Runners usually rarely use this running style.

[0003] With the rise of national fitness, running is becoming more and more popular, and more and more runners are participating in marathon events. In marathon events, most athletes use the forefoot landing running technique.

[0004] Most of the running shoes on the market are general-purpose running shoes, which are difficult to meet the needs of runners who run with the forefoot landing. As more and more runners participate in marathon events, people's functional requirements for professional sports shoes are getting higher and higher. Although there are a few running shoes designed for the forefoot landing running method, the sole structure is simple and focuses on propulsion, which cannot give a good balance between support stability and shock absorption performance.

[0005] In view of this, the applicant conducted an in-depth study on the above-mentioned issues, which led to the present case. Utility Model Content

[0034] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0035] like Figures 1 to 3 As shown, this embodiment provides a running shoe, including a sole, the sole including a sole body 100, and an upper (not shown in the figure) is arranged on the sole body 100, wherein the upper is a conventional upper, which is not the focus of this embodiment and will not be described in detail here. A quick-release shoelace buckle (not shown in the figure) is arranged on the upper for quickly adjusting the tightness of the shoelace. It should be noted that the quick-release shoelace buckle is a conventional structure, such as a quick-tightening shoelace buckle disclosed in the Chinese patent document with publication number CN 211558978 U.

[0036] It should be noted that the soles can also be sold separately before being made into running shoes, so this embodiment actually provides a kind of sole.

[0037] For the convenience of explanation, the direction of the sole of the foot when standing at attention after wearing is defined as down, and the opposite direction is defined as up; the direction pointed by the toe after wearing is defined as front, and the opposite direction is defined as back; the length direction of the shoe body 100 is the front-back direction. The side of the sole body 100 corresponding to the inner side of the human instep is defined as the inner side, and the side corresponding to the outer side of the human instep is defined as the outer side.

[0038] The sole body 100 provided in this embodiment includes a second elastic layer 110, a carbon plate 120 and a first elastic layer 130 stacked from top to bottom; the carbon plate 120 is used to enhance propulsion force.

[0039] The sole body 100 is divided into a forefoot section, a midfoot section and a heel section which are connected in sequence from front to back; the second elastic layer 110, the carbon plate 120 and the first elastic layer 130 are all divided into a forefoot section, a midfoot section and a heel section which are connected in sequence from front to back, wherein each forefoot section is an area of ​​the sole body 100 corresponding to the forefoot of the human foot, each midfoot section is an area of ​​the sole body 100 corresponding to the arch area of ​​the human foot, and each heel section is an area of ​​the sole body 100 corresponding to the heel of the human foot. Specifically, the second elastic layer 110 is divided from front to back into a forefoot section of the second elastic layer 110, a midfoot section of the second elastic layer 110, and a heel section of the second elastic layer 110, which are connected in sequence; the carbon plate 120 is divided from front to back into a forefoot section of the carbon plate 120, a midfoot section of the carbon plate 120, and a heel section of the carbon plate 120, which are connected in sequence; the first elastic layer 130 is divided from front to back into a forefoot section of the first elastic layer 130, a midfoot section of the first elastic layer 130, and a heel section of the first elastic layer 130, which are connected in sequence.

[0040] The forefoot section of the sole body 100 includes the forefoot section of the second elastic layer 110, the forefoot section of the carbon plate 120 and the forefoot section of the first elastic layer 130; the midfoot section of the sole body 100 includes the midfoot section of the second elastic layer 110, the midfoot section of the carbon plate 120 and the midfoot section of the first elastic layer 130; the heel section of the sole body 100 includes the heel section of the second elastic layer 110, the heel section of the carbon plate 120 and the heel section of the first elastic layer 130.

[0041] It should be noted that the forefoot section, midfoot section and heel section of the sole body 100 are a continuous whole, and the transition between each section is smooth. The sole body 100 is divided into three sections only for the convenience of explanation; similarly, the transition between each section in the second elastic layer 110 is also smooth, the transition between each section in the carbon plate 120 is also smooth, and the transition between each section in the first elastic layer 130 is also smooth.

[0042] The lower surface of the midfoot section of the first elastic layer 130 is a plane, and the lower surface of the forefoot section of the first elastic layer 130 is a curved surface. The lower surface of the forefoot section of the first elastic layer 130 and the lower surface of the heel section of the first elastic layer 130 are gradually lifted upward from one end close to the midfoot section of the first elastic layer 130 to one end away from the midfoot section of the first elastic layer 130. The lower surface of the heel section of the first elastic layer 130 includes a gentle curved surface 150, and the curvature of the gentle curved surface is smaller than the curvature of the lower surface of the forefoot section of the first elastic layer 130. One end of the midfoot section of the gentle arc surface 150 close to the first elastic layer 130 corresponds to the navicular bone of the human body. The arrangement of the gentle arc surface 150 allows the sole body 100 to form a heel-free structure, which is beneficial to reducing the weight of the sole body 100, allowing more efficient long-distance running, and achieving the purpose of saving energy metabolism, thereby facilitating long-distance running for runners who use the forefoot landing running method. At the same time, when the heel section needs to touch the ground during running or in the preparation stage for starting, the use of the gentle arc surface 150 can also make the contact area larger and the support more stable.

[0043] The thickness of the sole body 100 at a position corresponding to one end of the midfoot section of the gentle arc surface 150 close to the first elastic layer 130 is greater than the thickness of the sole body 100 at a position corresponding to one end of the midfoot section of the forefoot section of the first elastic layer 130 close to the first elastic layer 130. Specifically, the upper surface of the sole body 100 tends to gently descend from the position corresponding to one end of the midfoot section of the gentle arc surface 150 close to the first elastic layer 130 to the position corresponding to one end of the midfoot section of the forefoot section of the first elastic layer 130 close to the first elastic layer 130, so that a slope difference is formed on the upper surface of the sole body 100, which is beneficial to providing forward driving force and is beneficial to the forefoot landing running method.

[0044] The carbon plate 120 is provided with a hollow hole 121 at a position corresponding to the heel bone, and the second elastic layer 110 and the first elastic layer 130 are integrally connected at the position of the hollow hole 121, which is conducive to increasing the deformation space of the sole at the position corresponding to the heel bone, thereby improving the shock absorption performance. The midfoot section of the carbon plate 120 has an upper arch, and the midfoot section of the carbon plate 120 has a lower concave part, which conforms to the human foot shape structure, is conducive to ensuring support stability during running, and quickly recovers after deformation in the extension stage and provides forward and upward power.

[0045] The sole body 100 further includes an outsole 140 , which is fitted on the lower surface of the first elastic layer 130 . A pattern 141 is provided on the side of the outsole 140 facing the ground, which is beneficial to increase the grip of the outsole with the ground, thereby improving stability during running.

[0046] It should be noted that the outsole 140 is divided into a forefoot section of the outsole 140, a midfoot section of the outsole 140 and a heel section of the outsole 140 which are connected in sequence from front to back, wherein the forefoot section of the outsole 140 is located at a position corresponding to the forefoot section of the sole body 100, the midfoot section of the outsole 140 is located at a position corresponding to the midfoot section of the sole body 100, and the heel section of the outsole 140 is located at a position corresponding to the heel section of the sole body 100.

[0047] Furthermore, the density of the pattern 141 of the outsole 140 at the position corresponding to the forefoot section of the first elastic layer 130 is greater than the density of the pattern 141 of the outsole 140 at the position corresponding to the heel section of the first elastic layer 130; the density of the pattern 141 of the outsole 140 at the position corresponding to the inner side of the forefoot section of the first elastic layer 130 is greater than the density of the pattern 141 of the outsole 140 at the position corresponding to the outer side of the forefoot section of the first elastic layer 130; during the landing process of running, when running with the forefoot, the forefoot part lands slightly first, and then the heel also lands. When the forefoot lands, the outer side of the forefoot lands first, and then quickly transitions to the inner side of the forefoot and the heel; during the extension stage, there is a certain degree of internal rotation rolling extension from the outside to the inside, and the force on the inner side of the forefoot will be greater than that on the outside; the use of this technical solution is conducive to meeting the plantar force conditions of the runner during the entire gait cycle from landing to pushing off during running, and ensuring the stability of the running process.

[0048] As a preferred embodiment of the present invention, the length of the horizontal projection of the gentle arc surface 150 in the length direction of the sole body 100 is 65 mm to 75 mm, preferably 71.9 mm.

[0049] As a preferred embodiment of the present invention, the thickness of the sole body 100 at a position corresponding to one end of the midfoot section of the gentle arc surface 150 close to the first elastic layer 130 is 10 to 20 mm, preferably 16 mm, greater than the thickness of the sole body 100 at a position corresponding to one end of the midfoot section of the forefoot section of the first elastic layer 130 close to the first elastic layer 130. With this technical solution, the center of gravity of a runner who lands in the forefoot landing style is located in front of the middle waist, which can prevent the muscle strength from decreasing in the second half of the marathon, prevent the runner from leaning back when running, and keep the runner's body stable when running.

[0050] Furthermore, a groove 131 is provided at the lower end of the first elastic layer 130; a hollow through hole 132 penetrating the first elastic layer 130 is provided at the bottom surface of the groove 131. In this embodiment, the outer contour of the mouth of the lower end of the hollow through hole 132 is consistent in shape with the outer contour of the bottom of the groove and their positions coincide.

[0051] Furthermore, the outer bottom 140 is provided with a hollow opening 142 corresponding to the lower end surface of the sink 131. Specifically, the horizontal projection of the outer contour of the lower end surface of the sink 131 completely overlaps with the horizontal projection of the outer contour of the upper end of the hollow opening 142, or the outer contour of the horizontal projection of the lower end surface of the sink 131 is completely located within the outer contour of the horizontal projection of the upper end of the hollow opening 142. In this embodiment, the outer contour of the lower end surface of the sink 131 is consistent in shape with the outer contour of the upper end of the hollow opening 142 and overlaps in position.

[0052] By providing the sink groove 131, the hollow through hole 132 and the hollow opening 142, on the one hand, it is helpful to reduce the weight of the sole body 100 and facilitate the deformation of the carbon plate 120 during the pedaling and stretching stage. On the other hand, it allows consumers to directly see the carbon plate 120 and the shape of the sink groove 131 can also be designed. While ensuring the overall functionality, it provides a diverse design basis for the appearance design to meet the visual experience of consumers.

[0053] Furthermore, the horizontal projection of the groove 131 is Y-shaped. Furthermore, the horizontal projection of the cross section of the groove 131 close to the carbon plate 120 is completely within the horizontal projection of the cross section of the groove 131 away from the carbon plate 120 .

[0054] The present invention is described in detail above with reference to the accompanying drawings, but the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the prior art, all of which belong to the protection scope of the present invention.
