[0032] Example

[0033] The present utility model embodiment provides a shoe, which can be a sports shoe or a casual shoe. The shoe includes a shoe upper and an arch support sole 10 connected to the shoe upper. The arch support sole 10 can play a supporting role at the arch of the foot, effectively improving the problems of foot fatigue and ligament strain caused by the arch of the foot hanging in the air. The specific structure of each component of the arch support sole 10 provided in this embodiment and the corresponding relationship between them will be explained in detail below.

[0034] Figure 1 This is a schematic diagram of an outer sole 300 provided in an embodiment of the utility model. Figure 2 This is a schematic diagram of a side wall 500 provided in an embodiment of the utility model. Figure 3 For a schematic diagram of the inner sole 100 provided in an embodiment of the present invention, please refer to Figures 1 to 3 The utility model provides an arch support sole 10, which includes a support member 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.

[0035] The outsole 300 is provided with a first cavity 310 at a position corresponding to the arch of the foot, and the support member 700 cooperates with the first cavity 310. It is understandable that the design of the first cavity 310 can allow the arch support sole 10 to deform to a certain extent, so that the foot can bend naturally during walking and exercise; and the support member 700 fills the first cavity 310, which can reduce the feeling of the foot hanging in the shoe, provide stable support, reduce the overuse of the foot muscles and ligaments, and reduce foot fatigue.

[0036] On the basis of the above, the support member 700 is provided with a plurality of strip-shaped protrusions 710 at intervals along the length direction of the arch support sole 10. It can be understood that the provision of the strip-shaped protrusions 710 can, on the one hand, increase the friction between the arch support sole 10 and the ground, providing better grip; on the other hand, it can effectively disperse the impact of the ground on the foot, reduce the vibration of the arch and joints when walking or running, and reduce the excessive pressure in certain areas, avoiding the wearer from having fasciitis and other problems.

[0037] It should also be noted that the strip-shaped protrusion 710 extends along the width direction of the arch support sole 10, and can accordingly provide a certain support in the width direction of the arch support sole 10, thereby improving the torsion resistance and force conduction effect of the support member 700, providing a certain stability and supporting effect, and preventing the wearer's foot from twisting excessively and causing personal injury when walking and changing direction.

[0038] In addition, the specific shape of the support member 700 can imitate the natural shape of the arch of the foot to provide customized support. Optionally, along the length direction of the arch support sole 10, the support member 700 adopts a design that changes from narrow to wide and then from wide to narrow, that is, a design that is wide in the middle and narrow at both ends, so as to allow the wearer to ensure natural bending and movement when walking and exercising.

[0039] In some embodiments, the support member 700 is made of TPU material. It should be noted that TPU material is thermoplastic polyurethane elastomer, which is a polymer material between rubber and plastic, and has excellent comprehensive properties such as good elasticity, high strength, high toughness and wear resistance. The support member 700 made of this material has a slight supporting effect on the arch of the foot, and is not a hard support, which can ensure that the support pad supports the arch of the foot without forcing the plantar fascia to relax.

[0040] Please refer again Figure 1 Next, other structures of the outer sole 300 will be described in detail. Specifically, the outer sole 300 is provided with a second cavity 320, and the second cavity 320 extends from a position of the outer sole 300 corresponding to the forefoot of the foot to a position corresponding to the arch of the foot, and the first cavity 310 is recessed in the bottom wall of the second cavity 320.

[0041] Based on the above arrangement, it can be understood that the first cavity 310 and the second cavity 320 are arranged in layers along the thickness direction of the arch support sole 10, which can absorb and disperse the impact layer by layer, thereby achieving the technical effect of optimizing stress distribution and reducing stress concentration.

[0042] In some embodiments, anti-skid and drainage are also important factors to consider when designing the sole. The second cavity 320 is used to form a third cavity 330 inwardly corresponding to the forefoot of the foot, and a triangular bottom flower unit 331 is convexly formed on the bottom wall of the third cavity 330.

[0043] On the one hand, an outer channel 361 is formed between the third cavity 330 and the second cavity 320, and an inner channel 363 is formed between the second cavity 320 and the triangular bottom flower unit 331. The inner and outer channels 361 are mutually nested and support each other, which can provide better stability and anti-distortion ability. On the other hand, the triangular bottom flower unit 331 is convenient for increasing the roughness of the second cavity 320, forming a triangular casting bite design, and improving the anti-slip performance. Optionally, the bottom flower design in the second cavity 320 is made into a single IP shot, that is, a single injection molding.

[0044] Furthermore, since the triangular bottom flower unit 331 includes a plurality of triangular protrusions, a drainage groove is formed between any two adjacent triangular protrusions to achieve the technical effect of rapid drainage, increase the dry surface of the sole and reduce the moisture of the sole. Optionally, at least one side of any two adjacent triangles is opposite, that is, arranged in parallel, so as to form a straight drainage groove for easy drainage and avoid the accumulation of aqueous solution due to excessive bending of the drainage groove.

[0045] In order to further improve the drainage performance of the arch support sole 10, the outer sole 300 is further provided with a plurality of grooves 340, and any groove 340 is connected to the second cavity 320 at one end, and the other end extends to the connection between the outer sole 300 and the side wall 500. Based on the arrangement of the grooves 340, when the wearer walks in rainy days, the water inside the sole can be quickly squeezed out by stepping on the sole, thereby increasing the dry surface, reducing humidity, and facilitating all-weather travel.

[0046] Considering multi-directional drainage, the groove 340 includes a first groove 341 located at a position corresponding to the forefoot of the outsole 300 and a second groove 343 located at a position corresponding to the arch of the foot, and the first groove 341 and the second groove 343 are inclined away from the second cavity 320. It can be understood that the first groove 341 and the second groove 343 are radially designed, which can effectively guide the accumulated water from the center of the sole to the periphery.

[0047] Accordingly, in order to enhance the drainage capacity at the positions corresponding to the front and back and the heel of the sole, the outer sole 300 is further provided with a first V-shaped groove 351 and a second V-shaped groove 353, and the first V-shaped groove 351 is located at the position corresponding to the forefoot of the outer sole 300, and the second V-shaped groove 353 is located at the position corresponding to the heel of the outer sole 300, and the opening directions of the first V-shaped groove 351 and the second V-shaped groove 353 are opposite to each other. It should be noted that the design of the V-shaped groove 340 can quickly guide the flow of liquid and quickly drain water from the inclined two sides.

[0048] In addition, it should be noted that the above-mentioned first V-shaped groove 351, first groove 341, second groove 343 and second V-shaped groove 353 are arranged in sequence along the length direction of the arch support sole 10. While achieving large-area drainage, the outsole 300 is cut obliquely to form a plurality of oblique block surfaces, thereby maximizing the bending effect of the sole, thereby providing flexibility and comfort of the sole.

[0049] See also Figure 4The end of the outsole 300 away from the support member 700 is tilted upward to form a tilted structure 370, so as to reduce the possibility of the user falling due to slipping when walking, and to avoid the chain reaction that may occur when falling. In addition, considering that the tilted structure 370 is located at the front end of the arch support sole 10, it can effectively prevent the damage to the toes caused by external force impact. In addition, when the wearer walks in the rain, the heightened tilted structure 370 can also reduce the possibility of water on the ground being thrown onto the shoe surface due to inertia, thereby ensuring the dryness and comfort of the shoes.

[0050] See also Figure 2 and Figure 5 , the specific structure of the side wall 500 will be described below. Specifically, the side wall 500 is provided with a first step portion 510 and a second step portion 530 in sequence from top to bottom along the thickness direction of the arch support sole 10, and the extension length of the first step portion 510 along the width direction of the arch support sole 10 is greater than the extension length of the second step portion 530 along the width direction of the arch support sole 10. It can be understood that the first step portion 510 and the second step portion 530 are designed in steps, and the second step portion 530 is concavely designed, so as to optimize the energy transfer capacity of the side wall and improve the shock absorbing performance of the sole. Optionally, the first step portion 510 and the second step portion 530 are designed with a waist-tightening design at the corresponding position of the arch portion, so that the sole is more delicate and beautiful.

[0051] like Figure 6 As shown, the first step 510 and the second step 530 extend to the position corresponding to the sole and the heel, so that the side wall 500 there can also be deformed when under pressure, and quickly return to its original shape after the pressure is removed, thereby improving elasticity and energy rebound performance. In real life, the wearer can quickly put on the shoes without bending over, which improves convenience. In addition, the above design also achieves a strong visual effect and sensory effect transmission of the shock-absorbing and rebound performance.

[0052] Accordingly, if Figure 2 and Figure 5 The second step portion 530 is respectively provided with a first cushioning area 531 and a second cushioning area 533 on both sides along the width direction of the arch support sole 10, and the first cushioning area 531 and the second cushioning area 533 both extend from the position of the second step portion 530 corresponding to the arch of the foot to the position corresponding to the heel of the foot, and the first cushioning area 531 and the second cushioning area 533 are both recessed with a plurality of air holes 532.

[0053] It should be noted that the circular air hole 532 can be deformed into an elliptical shape when under pressure, and return to a circular shape after the pressure is released, which is similar to the visualization of spring rebound assistance, and intuitively displays the shock absorption performance to the wearer, enhancing the sensory effect. Also, similar to the performance of a spring structure, the air hole 532 can play a telescopic assistance effect, better protect the foot bones from external impact, and reduce the risk of injury to the wearer.

[0054] Please refer again Figure 3 The insole 100 is used to have a plurality of labor-saving grooves 110 at positions corresponding to the forefoot of the foot, and the plurality of labor-saving grooves 110 are sequentially spaced along the length direction of the arch support sole 10. Based on the above arrangement, the arch support sole 10 can be deformed as the toes are bent, 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 correspondingly recessed in the insole 100 to achieve the technical effect of better reducing the weight ratio of the sole, making the sole lighter and more comfortable.

[0055] In summary, the utility model provides an arch support sole 10 and a shoe, wherein the arch support sole 10 comprises a support member 700, an insole 100, an outsole 300, and a side wall 500 connected between the insole 100 and the outsole 300. Among them, the outsole 300 is used to open a first concave cavity 310 at a position corresponding to the arch of the foot, and the support member 700 cooperates with the first concave cavity 310. It can be understood that the design of the first concave cavity 310 can allow the foot to bend naturally during walking and exercise; and the support member 700 fills in the first concave cavity 310, which can reduce the suspended feeling of the foot in the shoe, provide stable support, and reduce foot fatigue. On the basis of the above, the support member 700 is provided with a plurality of strip-shaped protrusions 710 at intervals along the length direction of the arch support sole 10. It can be understood that the arrangement of the strip-shaped protrusions 710 provides better grip and effectively disperses the impact force of the ground on the foot, avoiding problems such as fasciitis in the wearer.

[0056] 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.
