[0008] Based on the first aspect mentioned above, in some embodiments, each angle of the acute triangle is rounded.
[0009] Based on the first aspect described above, in some embodiments, the apex angle of the first hole located in the first main force-bearing area faces the lower surface of the sole, and the bottom edge of the first hole located in the first main force-bearing area faces the upper surface of the sole. Similarly, the apex angle of the second hole located in the second main force-bearing area faces the lower surface of the sole, and the bottom edge of the second hole located in the second main force-bearing area faces the upper surface of the sole.
[0010] Based on the first aspect above, in some embodiments, the apex of the hole located at the crest of the wave-like structure faces the lower surface of the sole and the bottom edge faces the upper surface of the sole, and the apex of the hole located at the trough of the wave-like structure faces the upper surface of the sole and the bottom edge faces the lower surface of the sole.
[0011] Based on the first aspect above, in some embodiments, the apex of each hole faces the lower surface of the sole and the bottom edge faces the upper surface of the sole, or the apex faces the upper surface of the sole and the bottom edge faces the lower surface of the sole, and the number of holes with the apex facing the upper surface of the sole is less than the number of holes with the apex facing the lower surface of the sole.

[0018] In the aforementioned sole and shoes using such soles, the presence of multiple perforations reduces the weight of the sole, thus making the overall weight of the shoe lighter. This improves shoe comfort and reduces material costs. Furthermore, the perforated design enhances breathability. Secondly, the presence of multiple perforations allows the sole to absorb some impact when the user steps down, providing cushioning and protection for the foot. The perforations also improve the sole's rebound performance. The absence of perforations at the arch area further enhances the sole's support. In summary, the presence and distribution of these perforations contribute to improved sole comfort. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0027] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0028] Please see Figure 1 One embodiment of this application provides a shoe 100, including a sole 10 and an upper 20. The upper 20 is combined with the sole 10.
[0029] Please see Figure 1 and Figure 2 The sole 10 includes a heel portion 11, a forefoot portion 13, and an arch portion 15 connecting the heel portion 11 and the forefoot portion 13. The sole 10 also includes a plurality of holes 17 spaced apart along a front-rear direction X. Each hole 17 extends from a side 12 of the sole 10 along a left-right direction Y. The plurality of holes 17 are distributed in the heel portion 11 and the forefoot portion 13 of the sole 10, excluding the arch portion 15. It is understood that the front-rear direction X is perpendicular to the left-right direction Y.
[0030] Specifically, the plurality of holes 17 include a plurality of first holes 17a distributed on the rear palm portion 11 and a plurality of second holes 17b distributed on the forepal portion 13.
[0031] In the aforementioned shoe 100, firstly, the presence of multiple holes 17 in the sole 10 reduces the weight of the sole 10, thus making the overall weight of the shoe 100 lighter. This improves the comfort of the shoe 100 and also reduces material costs. Furthermore, the multi-hole design enhances the breathability of the sole 10. Secondly, the presence of multiple holes 17 allows the sole 10 to absorb some of the impact when the user steps down, providing cushioning and protection for the foot. The presence of multiple holes 17 also improves the rebound performance of the sole 10. The fact that the holes 17 are not located in the arch area 15 further enhances the support effect of the sole 10. In summary, the presence and distribution of the holes 17 contribute to improving the comfort of the sole 10.
[0032] Understandably, the heel portion 11 has a first primary force-bearing area 111 and a first secondary force-bearing area 113 connected to the first primary force-bearing area 111 in the front-rear direction X, and the forefoot portion 13 has a second primary force-bearing area 131 and a second secondary force-bearing area 133 connected to the second primary force-bearing area 131 in the front-rear direction X. In some embodiments, the volume of the first hole 17a located in the first primary force-bearing area 111 may be larger than the volume of the first hole 17a located in the first secondary force-bearing area 113, and the volume of the second hole 17b located in the second primary force-bearing area 131 may be larger than the volume of the second hole 17b located in the second secondary force-bearing area 133. The larger the hole in the primary force-bearing area, the better the shock absorption effect, and therefore the better the cushioning effect of the primary force-bearing area. The holes in the secondary force-bearing area are relatively smaller. The two work together to improve the cushioning effect while ensuring the overall support effect of the sole 10.
[0033] In some embodiments, such as Figure 1 and Figure 2 As shown, each hole 17 in the cross-section along the front-rear direction X of the sole 10 can be an acute triangle. Because the sides of the triangular structure can guide the pressure on the sole 10 to multiple directions, it disperses the pressure, reduces local stress concentration, improves the cushioning effect of the sole 10, and reduces damage to the sole 10 itself. Secondly, the stability of the triangular structure can enhance the controllable deformation of the sole 10 during compression. For example, when the foot strikes the ground, the distribution of multiple triangular holes in the front-rear direction X can prolong the pressure absorption time through orderly deformation of sequential compression and rebound, thereby further dispersing the pressure and improving the cushioning effect. Furthermore, the high geometric stability of the triangular structure can reduce the torsional deformation of the sole under lateral force, enhancing the dynamic support of the sole 10 during use, such as running. In addition, the triangular structure can accelerate the recovery speed after deformation under force, improving the continuity of energy conversion in the shoe, thus achieving a more sensitive rebound response.
[0034] Understandably, each of the acute-angled triangular holes 17 includes a base 171 and a apex α that is vertically opposite to the base 171.
[0035] Furthermore, the corners of the triangular hole 17 can also be rounded, which helps to further reduce the risk of local stress concentration, thereby reducing the fatigue risk of the sole 10 and extending the service life of the sole 10.
[0036] In some embodiments, the apex α of the first hole 17a located in the first main force-bearing area 111 may face the lower surface 10a of the sole 10, and the bottom edge 171 of the first hole 17a located in the first main force-bearing area 111 may face the upper surface 10b of the sole 10; the apex α of the second hole 17b located in the second main force-bearing area 131 may face the lower surface 10a of the sole 10, and the bottom edge 171 of the second hole 17b located in the first main force-bearing area 111 may face the upper surface 10b of the sole 10. When the sole 10 is impacted, the structure of the triangular holes corresponding to the main force-bearing areas (111 and 131) with the apex pointing downwards and the bottom edge pointing upwards is beneficial for providing better cushioning effect initially through a larger deformation space, and for providing better support force through the apex angle to achieve better rebound effect subsequently, thereby improving the comfort of the shoe 100.
[0037] In some embodiments, such as Figure 2 The centers of the plurality of first holes 17a can be arranged in a wave-like structure in the front-back direction X, and the centers of the plurality of second holes 17b can be distributed in a wave-like structure in the front-back direction X. The specific distribution of the first holes 17a and second holes 17b has a certain guiding effect on the force when impacted, improving the cushioning effect and helping to improve the rebound effect after the cushioning ends. When running outdoors, the front and back wave-like design has a better rolling transition effect when the sole alternates with the ground (i.e., the rolling is smoother), thereby improving the user's experience.
[0038] Furthermore, both the first hole 17a and the second hole 17b located at the crests of the wave-like structure satisfy the condition that the apex angle α faces the lower surface 10a of the sole 10 and the bottom edge 171 faces the upper surface 10b of the sole 10. Similarly, both the first hole 17a and the second hole 17b located at the troughs of the wave-like structure satisfy the condition that the apex angle α faces the upper surface 10b of the sole 10 and the bottom edge 171 faces the lower surface 10a of the sole 10. The combination of the downward-facing apex angle and upward-facing bottom edge of the holes closer to the foot, and the upward-facing apex angle and downward-facing bottom edge of the holes closer to the ground, helps the sole to provide better support while offering better cushioning and rebound, thereby further improving the comfort of the sole.
[0039] In some embodiments, each hole 17 may satisfy either the apex angle α facing the lower surface 10a and the bottom edge 171 facing the upper surface 10b, or the apex angle α facing the upper surface 10b and the bottom edge 171 facing the lower surface 10a. Further, the number of holes 17 in the sole 10 satisfying the apex angle α facing the lower surface 10a and the bottom edge 171 facing the upper surface 10b is greater than the number of holes 17 in the sole 10 satisfying the apex angle α facing the upper surface 10b and the bottom edge 171 facing the lower surface 10a, thereby further improving the cushioning effect of the sole 10 and thus further protecting the user's feet.
[0040] In some embodiments, each hole 17 may also be of other shapes on a cross section along the front-rear direction X of the sole 10, for example, as shown in the figure. Figure 3 As shown, it can be, but is not limited to, a rhombus shape.
[0041] like Figure 2 and Figure 3 As shown, a chamfer structure can be further formed between the outer end face of each hole 17 and the side surface 12 of the sole 10. When the sole 10 is subjected to force, the deformation of the hole 17 is smoother, which helps to further improve the shock absorption effect of the sole 10.
[0042] The hole 17 can be a blind hole or a through hole. In this embodiment, the hole 17 is a through hole that penetrates the sole 10 along the left-right direction X, which helps to improve the overall cushioning and rebound effect of the sole 10. Specifically, each of the first holes 17a and each of the second holes 17b are through holes.
[0043] Furthermore, in some embodiments, the area of each hole 17 in the cross section in the front-rear direction X gradually decreases from the side 12 of the sole 10 inward, thereby improving the overall stability of the sole 10 while providing a cushioning effect, thus better protecting the user's feet and improving comfort.
[0044] Specifically, in some embodiments, each hole 17 may be a stepped hole, comprising at least two regions, wherein the area of the cross-section of the region of the hole 17 near the side 12 of the sole 10 in the front-rear direction X is greater than the area of the cross-section of the region of the hole 17 away from the side 12 of the sole 10 in the front-rear direction X. That is, the area of the cross-section of each hole 17 in the front-rear direction X gradually decreases in a stepped manner, moving inward from the side 12 of the sole 10.
[0045] In other embodiments, the area of each hole 17 in the front-rear direction X may decrease linearly from the side 12 of the sole 10 inward.
[0046] like Figure 4 and Figure 5 As shown, the outer periphery of the upper surface 10b of the sole 10 may also be provided with an annular protrusion 18, which cooperates with the upper surface 10b to form an accommodating space 19 for placing the foot. To improve the fit and comfort of the foot, the surface 180 of the protrusion 18 facing the accommodating space 19 may be an inclined surface. Specifically, the end of the inclined surface away from the upper surface 10b is inclined in a direction away from the central axis of the accommodating space 19. Furthermore, the shape of the inclined surface may be designed to roughly mimic the shape of the corresponding area of the foot, thereby further improving the support and comfort.
[0047] The shoe 100 described in this application, due to the presence of multiple holes 17 in the sole 10, can reduce the weight of the sole 10, thereby making the overall weight of the shoe 100 lighter. This is beneficial for improving the comfort of the shoe 100 and also for reducing the cost of materials used. Furthermore, the multi-hole design can improve the breathability of the sole 10. Secondly, the presence of multiple holes 17 allows the sole 10 to absorb some of the impact when the user steps down, thus providing cushioning protection for the foot. At the same time, the presence of multiple holes 17 also helps to improve the rebound performance of the sole 10. The fact that the holes 17 are not located in the arch area 15 further enhances the support effect of the sole 10. In summary, the presence and distribution of the holes 17 are beneficial for improving the comfort of the sole 10.
[0048] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
