Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of soles, in particular to a sole and a shoe capable of reducing sole friction. Background Art
[0002] When people exercise, the change of plantar pressure is a dynamic and complex process, which generally includes the following situations:
[0003] Landing phase: During exercise, a noticeable pressure peak is generated during the foot landing phase. The size and location of this peak depends on the type of exercise and the individual's landing method. For example, when running, if the rear foot lands, the heel will touch the ground first and bear greater impact force; while if the forefoot lands, the forefoot and toes will touch the ground first and bear pressure.
[0004] Support phase: After the foot is fully on the ground, the pressure on the sole of the foot will be distributed to a wider area, including the arch, midfoot and forefoot. During this phase, the pressure distribution on the sole of the foot will change depending on factors such as the type of movement, speed and gait.
[0005] Push-off phase: For sports that require pushing off the ground (such as running, jumping, etc.), the forefoot and toe areas will be under greater pressure during the push-off phase. This is because these areas need to generate enough thrust to propel the body forward or upward when pushing off the ground.
[0006] Due to the changes in movements during exercise, such as from the support stage to the push-off stage, the contact surface between the sole of the foot and the sole of the shoe will produce micro friction due to movement, which can easily lead to foot pain, blisters and other problems over time. However, in existing sports shoes, the sole cannot deform according to different force conditions to reduce the friction of the sole of the foot. Summary of the invention
[0007] The utility model aims to provide a shoe sole and a shoe for reducing sole friction, so as to solve the problem of sole pain and blistering caused by micro-friction between the shoe sole and the sole.
[0008] To achieve the above-mentioned purpose, the utility model discloses a sole for reducing sole friction, comprising: a sole main body, a forefoot portion of the sole main body being provided with an elastic strain zone, the strain zone being composed of a plurality of force-bearing blocks, a strain groove being provided on the periphery of the force-bearing blocks, and the side surfaces of the strain groove being the deformation surfaces of the force-bearing blocks.
[0009] Preferably, there are two stress-bearing blocks in total, which are arranged along the width direction of the sole body, and the position of the strain zone corresponds to the front toe area of the human foot.
[0010] Preferably, the deformation surface is an arc-shaped surface, and the cross-section of the strain groove is a structure that is narrow at the top, wide in the middle, and narrow at the bottom.
[0011] Preferably, the ratio of the length of the narrower part of the upper portion of the strain groove to the wider part of the middle portion is 1:2.
[0012] Preferably, the depth of the strain groove is 0.5-1.5 cm, and the widest part in the middle of the strain groove is 1-3 cm.
[0013] Preferably, the sole body includes an outsole and a midsole, and the strain zone is arranged in the midsole.
[0014] Preferably, the strain zone material is the same as the midsole material.
[0015] Preferably, the midsole is provided with two layers, and the strain zone is provided between the two layers of the midsole.
[0016] Preferably, the sole body is provided with strain areas corresponding to the heel and the lateral area of the foot of the human body.
[0017] Preferably, a shoe comprises an upper and a sole body, wherein the upper is fixedly connected to the sole body.
[0018] The utility model has the following beneficial effects:
[0019] 1. The utility model causes the side of the strain groove to deform by applying force to the force-bearing block, thereby absorbing forces of different magnitudes, reducing the relative movement of the foot and the sole, and further reducing the friction between the sole and the sole of the foot.
[0020] 2. Provide better support for the sole of the foot through the setting of strain zones. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0029] Embodiment 1
[0030] like Figures 1 to 3 As shown, the utility model provides a sole for reducing sole friction, including: a sole body 100, a forefoot portion of the sole body 100 is provided with an elastic strain zone 110, the strain zone 110 is composed of a plurality of force-bearing blocks 111, a strain groove 112 is provided on the periphery of the force-bearing block 111, and the side surface of the strain groove 112 is a deformation surface 113 of the force-bearing block 111.
[0031] In this embodiment, there are two force-bearing blocks 111, which are arranged along the width direction of the sole body 100. The position of the strain area 110 corresponds to the front toe area of the human foot. The middle part of the front toe area of the human body is slightly concave, forming a dividing line, dividing the front toe area into two parts, and the two force-bearing blocks 111 just correspond to these two parts. When the front toe area applies force to the sole, these two parts can effectively absorb the force of the front toe area, thereby reducing the friction between the foot and the sole.
[0032] like Figure 3 As shown, the deformation surface 113 is an arc-shaped surface, and the cross-section of the strain groove 112 is a structure that is narrow at the top, wide in the middle, and narrow at the bottom. In this embodiment, the narrower part of the upper part of the strain groove 112 ( Figure 3 e) and the wider middle part ( Figure 3 The ratio of the length of the strain groove 112 to the length of the strain groove 112 at the middle d is 1:2, the depth c of the strain groove 112 is 0.5~1.5cm, and the widest part d in the middle of the strain groove 112 is 1~3cm. The narrow top of the strain groove 112 is conducive to improving the flatness of the contact surface with the sole of the foot and improving comfort. The deeper the depth of the strain groove 112 and the wider the middle part, the larger the range of adjusting the strain force and the better the effect. When the force-bearing block 111 is subjected to pressure, the deformation surface 113 deforms to effectively absorb the pressure.
[0033] The sole body 100 includes an outsole 101 and a midsole 102, and the strain zone 110 is arranged on the midsole 102. In this embodiment, the strain zone 110 and the midsole 102 are an integral structure, and the material of the strain zone 110 is the same as that of the midsole 102. The material of the strain zone 110 is EVA, PEBA, ETPU, etc. The material of the strain zone 110 is the same as that of the midsole 102, which can improve the integrity of the sole body 100 and reduce the difficulty of producing the sole body 100.
[0034] Embodiment 2
[0035] like Figure 4 As shown, the difference between this embodiment and the first embodiment is that the midsole 102 is provided with two layers, and the strain zone 110 is provided between the two layers of the midsole 102. Such a configuration can improve the flatness of the sole when in contact with the sole, and improve comfort.
[0036] Embodiment 3
[0037] like Figure 5 As shown, the difference between this embodiment and the first embodiment is that the sole body 100 is provided with strain areas 110 corresponding to the heel and the lateral area of the foot of the human body. In this embodiment, when the sole of the foot exerts a large pressure on the corresponding position of the sole, the strain area 110 in this area will absorb the excessive pressure, reducing the friction between the foot and the sole caused by the excessive pressure, thereby providing good protection for the sole of the foot.
[0038] Embodiment 4
[0039] The difference between this embodiment and the first embodiment is that a shoe comprises an upper and a sole body 100, wherein the upper is fixedly connected to the sole body 100. In this embodiment, the shoe using the sole body 100 can reduce sole friction and protect the foot.
[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
