[0030] Example

[0031] The embodiment of the utility model provides a shoe, which can be a sports shoe, a travel shoe or a casual shoe. The shoe includes an upper and a sprain-proof shock-absorbing sole 10, and the upper is fixedly connected to the sprain-proof shock-absorbing sole 10. The sprain-proof shock-absorbing sole 10 can provide sufficient stability and protection for the ankle joint, avoid the risk of sprains that may occur during exercise, and at the same time can reduce foot fatigue and improve overall comfort. Below, the specific structure of each component of the sprain-proof shock-absorbing sole 10 provided in this embodiment and the corresponding relationship between them will be explained in detail.

[0032] Figure 1 A schematic diagram of a side wall 500 provided in an embodiment of the utility model, Figure 2 A schematic diagram of an outer sole 300 provided in an embodiment of the utility model, Figure 3 For a schematic diagram of the inner sole 100 provided by the embodiment of the utility model, please refer to Figures 1 to 3The present application provides a sprain-proof and shock-absorbing sole 10, which includes a U-shaped patch 700, an insole 100, an outsole 300, and a side wall 500 connected between the insole 100 and the outsole 300, wherein the insole 100 is used to contact the foot, and the outsole 300 is used to contact the ground.

[0033] The side wall 500 is provided with a first layer 510 and a second layer 530 in sequence along the thickness direction of the sprain-proof shock-absorbing sole 10, and the first layer 510 is convex relative to the second layer 530. Based on the above arrangement, the first layer 510 and the second layer 530 are designed to be cut into upper and lower double-layer blocks. During walking, the sprain-proof shock-absorbing sole 10 can achieve a visual effect of upper and lower compression on the side wall 500, intuitively presenting shock-absorbing resilience, so as to fully demonstrate the technical effect of reducing foot fatigue and providing good comfort.

[0034] Furthermore, the second layer 530 is provided with two shock absorbing units 531 in a relative manner along the width direction of the anti-sprain shock absorbing sole 10, and the shock absorbing units 531 are both located at positions corresponding to the heel of the second layer 530. It can be understood that the above design can provide consistent support and shock absorption to the left and right sides of the instep, so as to maintain the balance of the wearer's gait when walking, and reduce sprains or other injuries caused by uneven force.

[0035] Figure 4 Another schematic diagram of the anti-sprain shock absorbing sole 10 provided by the embodiment of the utility model is as follows Figure 4 As shown, the U-shaped patch 700 is connected to the first layer 510 and is located at a position corresponding to the first layer 510 and the heel. In other words, the wearer's ankle and heel are located in the U-shaped patch 700, and are wrapped and effectively protected by the U-shaped patch 700 to prevent the risk of excessive twisting of the foot and causing sprains when walking and changing directions. In addition, the U-shaped patch 700 can be extended to a certain extent along the thickness direction of the anti-sprain shock-absorbing sole 10 on the basis of the side wall 500, so as to better support the ankle and improve stability.

[0036] Optionally, the U-shaped patch 700 is made of TPU material. It should be noted that TPU material is thermoplastic polyurethane elastomer, a polymer material between rubber and plastic, which has excellent load-bearing capacity, impact resistance and shock absorption performance. The U-shaped patch 700 made of TPU material can reduce unnecessary lateral movement of the foot during exercise and reduce the risk of sprain while providing sufficient stability and protection for the ankle joint.

[0037] Please refer again Figure 1Next, the shock absorption performance of the side wall 500 will be explained in detail. In some implementations, any shock absorption unit 531 first increases and then contracts along the length direction of the anti-sprain shock absorbing sole 10, presenting a structural design that is wide in the middle and narrow at both ends, so as to achieve the functional utility of optimizing stress distribution, and limitedly transmitting and dissipating impact force.

[0038] Furthermore, any one of the shock absorbing units 531 is recessed with a plurality of shock absorbing air holes 533. It is understandable that the circular shock absorbing air holes 533 can be deformed into an elliptical shape when under pressure, and return to a circular shape after the pressure is released. In the above dynamic process, the shock absorbing air holes 533 assist in deformation and expansion and contraction, thereby better protecting the position of the ankle joint of the foot from external force impact and reducing the risk of sprains. In addition, it should be noted that the above deformation process is similar to the compression and rebound of a spring, which fully visualizes the shock absorbing and rebound function.

[0039] In order to improve the shock absorption of the first layer 510, the first layer 510 is provided with a plurality of line grooves 511 at intervals along the thickness direction of the anti-sprain shock-absorbing sole 10. It should be noted that the plurality of line grooves 511 arranged at intervals can provide deformation buffer space, so as to facilitate the dispersion and elimination of impact force when under pressure. In order to improve the overall shock absorption function, any line groove 511 extends from the position of the first layer 510 corresponding to the sole to the position of the first layer 510 corresponding to the heel. In addition, it should be noted that the line groove 511 can be a straight groove 511 or a curved groove 511, which is not limited in this embodiment.

[0040] See also Figure 2 Next, the outsole 300 of the sprain-proof shock-absorbing sole 10 will be explained in detail. In some embodiments, the outsole 300 is provided with a first rubber patch 311, a second rubber patch 313, and a third rubber patch 315 at a position corresponding to the heel, and the first rubber patch 311, the second rubber patch 313, and the third rubber patch 315 are connected at an angle and surround to form a U-shaped area. Based on the above arrangement, the easily worn area of ​​the sprain-proof shock-absorbing sole 10 is locally strengthened, effectively extending the service life of the sole.

[0041] It is understandable that the rubber material itself has good friction performance, which can improve the grip of the shoes. In addition, special patterns or protrusions can be designed in the rubber patch accordingly to improve the grip. For example, a plurality of "cross"-shaped grooves connected in sequence are concavely arranged in the first rubber patch 311 and the third rubber patch 315, or a plurality of arc grooves are concavely arranged in the second rubber patch 313 along the length direction of the anti-sprain shock-absorbing sole 10.

[0042] Furthermore, the outer sole 300 is also provided with an annular shock-absorbing groove 317, and the annular shock-absorbing groove 317 is located in the U-shaped area. It can be understood that the area surrounded by the annular shock-absorbing groove 317 is convexly arranged upward relative to the annular shock-absorbing groove 317, and a shock-absorbing rebound portion is formed accordingly. In particular, when the annular shock-absorbing groove 317 is arranged in a teardrop shape, the above-mentioned shock-absorbing rebound portion is a teardrop-shaped protrusion, which is squeezed and deformed when subjected to pressure, and rebounds efficiently when the pressure is removed, forming a shock-absorbing and rebounding mechanism of one absorption and one rebound, thereby improving comfort.

[0043] In order to improve the drainage of the anti-sprain shock-absorbing sole 10, the first rubber patch 311, the second rubber patch 313 and the third rubber patch 315 can be provided with a first drainage groove 319 connected to the annular shock-absorbing groove 317, so as to quickly drain the accumulated water in the groove to avoid forming a lubricating layer that affects the anti-slip property of the rubber patch. Optionally, the first drainage groove 319 extends from one end of the annular shock-absorbing groove 317 to the connection between the rubber patch and the side wall 500.

[0044] According to the force analysis point of the foot, the sole of the sole is also a position that is easily worn. Based on this, the fourth rubber patch 331 and the fifth rubber patch 333 are provided at the position corresponding to the sole of the foot of the outsole 300, and the fourth rubber patch 331 and the fifth rubber patch 333 are connected at an angle and sandwiched to form a V-shaped area. It can be understood that the specific functions of the rubber patch have been described in detail in the previous text and will not be repeated here.

[0045] Correspondingly, the fourth rubber patch 331 and the fifth rubber patch 333 may also be provided with anti-skid protrusions 335 to increase the contact area with the ground, thereby increasing the friction force. Specifically, the connection between the fourth rubber patch 331 and the fifth rubber patch 333 may be relatively provided with multiple linear grooves along the width direction of the anti-sprain shock-absorbing sole 10, so as to increase multiple friction resistances during walking and better improve the anti-skid performance. The other areas of the fourth rubber patch 331 and the fifth rubber patch 333 may be provided with multiple interconnected "cross"-shaped grooves.

[0046] In addition, it should be noted that Figure 5 As shown, the connection between the fourth rubber patch 331 and the fifth rubber patch 333 is tilted upward toward the front end of the anti-sprain shock-absorbing sole 10 to form a forward tilting structure 370 to prevent the wearer from falling due to slipping when walking, thereby causing a series of chain reactions. Accordingly, since the forward tilting structure is arranged at the front of the shoe, it also prevents the external impact force from directly causing impact damage to the toes.

[0047] In order to further improve the anti-skid and shock-absorbing properties of the outer sole 300, the outer sole 300 is provided with a plurality of anti-skid protrusions 335 at intervals along the length direction of the anti-sprain shock-absorbing sole 10, and the anti-skid protrusions 335 are located in the V-shaped area. Based on the arrangement of the above anti-skid protrusions 335, on the one hand, the ground reaction force can be dispersed during walking or exercise to avoid single force and improve shock absorption. On the other hand, it can be easily embedded in the tiny gaps in the ground to form more friction points and improve the anti-skid property. Optionally, the anti-skid protrusions 335 can be set as V-shaped protrusions or diamond-shaped protrusions, and the surface is provided with triangular patterns.

[0048] In addition, it should be noted that a water channel is formed between any two adjacent shock-absorbing protrusions. To avoid the accumulation of water, similar to the design of the first drainage groove 319, the fourth rubber patch 331 and the fifth rubber patch 333 can also be provided with a second drainage groove 337 connected to the water channel. Similarly, the end of the second drainage groove 337 away from the water channel can also extend to the connection between the rubber patch and the side wall 500 to improve drainage efficiency.

[0049] Based on the design of the first drainage groove 319 and the second drainage groove 337, the outer sole 300 forms a large-area drainage groove structure, so that the function of rapid drainage can be achieved on rainy days. Specifically, on rainy days, when the wearer steps on the sole, the water inside the anti-sprain shock-absorbing sole 10 can be quickly squeezed out, thereby achieving the effect of increasing the dry surface and reducing humidity, which is convenient for all-weather travel.

[0050] In some embodiments, considering that the arch of the foot can act as a natural shock absorber to absorb the ground reaction force when walking, running or jumping, in order to improve its comfort and flexibility. The outsole 300 is relatively provided with two recesses 351 along the width direction of the anti-sprain shock-absorbing sole 10, and the two recesses 351 are both located at the position corresponding to the arch of the foot on the side wall 500. It can be understood that the provision of the above two recesses 351 can increase the deformability of the sole, thereby better fitting the arch of the foot in dynamic movement and improving the support performance.

[0051] Furthermore, in order to improve the anti-slip effect on the arch of the foot, two recesses 351 are sandwiched to form a transition table. The transition table is recessed with multiple triangular chambers 353 step by step along the thickness direction of the anti-sprain shock-absorbing sole 10. It should be noted that the triangular chamber 353 can effectively decompose and dissipate stress when impacted due to its stability. In addition, multiple triangular chambers 353 are recessed step by step, and the layers are compressed and rebounded with each other, which can further optimize the shock absorption effect, thereby providing effective protection.

[0052] Please refer again Figure 3, a plurality of labor-saving grooves 110 are recessed at the position corresponding to the sole of the foot on the insole 100, and the plurality of labor-saving grooves 110 are spaced apart along the length direction of the sprain-proof shock-absorbing sole 10. Based on the arrangement of the labor-saving grooves 110, the sprain-proof shock-absorbing sole 10 can be deformed along with the bending deformation of the toe portion, avoiding the situation where bending is difficult due to material accumulation, and achieving the technical effect of labor-saving forward movement. Moreover, in some embodiments, some hollow circular holes can be recessed in the insole 100 accordingly, so as to achieve the technical effect of better reducing the weight ratio of the sprain-proof shock-absorbing sole 10, making the sole lighter and more comfortable.

[0053] In summary, the present application provides a sprain-proof shock-absorbing sole 10 and a shoe, which includes a U-shaped patch 700, an insole 100, an outsole 300, and a side wall 500 connected between the insole 100 and the outsole 300. The side wall 500 is sequentially provided with a first layer 510 and a second layer 530 along the thickness direction of the sprain-proof shock-absorbing sole 10, so that during walking, the first layer 510 and the second layer 530 act on each other to compress and rebound, thereby reducing foot fatigue and improving comfort. In addition, the second layer 530 is relatively provided with two shock-absorbing units 531 along the width direction of the sprain-proof shock-absorbing sole 10, and the shock-absorbing units 531 are both located at the position corresponding to the second layer 530 and the heel, so as to maintain the balance of the wearer's gait when walking and reduce sprains or other injuries caused by uneven force. The U-shaped patch 700 is connected to the first layer 510 and is located at a position of the first layer 510 corresponding to the heel, so as to prevent the risk of sprain caused by excessive twisting of the foot during walking and changing direction.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
