[0026] Exemplary embodiments of the present invention will now be described more fully with reference to the accompanying drawings. However, it should not be construed that the embodiments of the present invention are limited to those described herein. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0027] This utility model provides a shoe sole, which can be mainly used as the sole of canvas shoes. The following will refer to... Figures 1 to 7 The structure of the shoe sole according to this utility model is described in detail.

[0028] In this article, for ease of description and understanding, directions (e.g., front, back, up, down, inside, outside) are defined based on the direction in which the shoes are worn on the feet.

[0029] Referring to the accompanying drawings, the sole may include a one-piece molded bottom member 10 and a side member 20, the side member 20 surrounding the outer peripheral edge of the bottom member 10 and extending upward. Figure 1 and Figure 2 As shown, with Figure 2 With line AA as the boundary, the side member 20 may include an inner side member 21 and an outer side member 22. At least one of the inner side member 21 and the outer side member 22 may have a curved upper surface in the tibial direction of the sole. For example, the curved upper surface may be a wavy upper surface, a concave-convex upper surface, or a convex upper surface with a concave middle section. When the upper surface of the side member 20 is formed with a curved shape, the flexibility of the sole during walking can be improved, and the pressure on the sole of the foot can be distributed, thereby improving the comfort of wearing the shoe.

[0030] In this article, it should be noted that: lines AA, BB, CC, and DD are virtual lines rather than actual lines on the sole. These lines are used to facilitate a clearer description of the sole structure. The two ends of the inner member 21 and the outer member 22 can refer to the positions where the inner member 21 and the outer member 22 intersect with AA, respectively.

[0031] like Figure 3 As shown, according to a preferred embodiment of the present invention, the upper surfaces of both the inner member 21 and the outer member 22 can have a shape that is concave downward in the middle relative to both ends, thereby forming a unique side profile resembling a smiley face. This design can naturally adapt to the swinging of the foot during walking, better distributing pressure on the sole and improving wearing comfort. For example, when walking, the point of force on the foot changes with the alternation of steps, and the curved shape of the side member 20 can ensure that the pressure is evenly distributed in various areas of the sole, avoiding excessive local pressure.

[0032] According to the embodiment of the utility model, the bottom component 10 and the side component 20 are integrally formed, in addition, the sole further includes an upper component 30 which extends inwardly from the front end upper surface of the side component 20 and is integrally formed with the side component 20.

[0033] The upper component 30 is formed in a narrow strip shape with a gradually changing width, specifically, the upper component 30 extends from the boundary line A-A of the inner side component 21 and the outer side component 22 along the upper surfaces of the inner side component 21 and the outer side component 22 towards both sides, and the width of the upper component 30 gradually decreases from the boundary line A-A towards both sides. Figure 2 As shown in the figure, the width becomes zero at the position corresponding to the line B-B.

[0034] In addition, in order to avoid the sole being too heavy, the ratio between the width W3 of the upper component 30 at the boundary line A-A and the length L1 of the sole can be within the range of 1 / 15 to 1 / 10.

[0035] Figure 3 A side view of the sole is shown. Figure 3 As shown in the figure, according to the preferred embodiment of the utility model, the inner side component 21 and the outer side component 22 can have the same shape and the same bending amplitude, and the heights of the upper surfaces of the inner side component 21 and the outer side component 22 at the corresponding positions on the inner and outer sides are the same. In this case, the ratio between the minimum distance L3 between the upper surfaces of the inner side component 21 and the outer side component 22 at the middle position and the bottom surface of the sole (i.e., the distance between the upper surfaces of the inner side component 21 and the outer side component 22 at the middle position and the bottom surface of the sole) and the maximum distance L4 between the upper surfaces of the inner side component 21 and the outer side component 22 at the heel position and the bottom surface of the sole (i.e., the distance between the upper surfaces of the inner side component 21 and the outer side component 22 at the heel position and the bottom surface of the sole) can be less than or equal to 0.5. In this way, the weight of the sole can be reduced, the sole can have sufficient support and good pressure dispersion effect, and the side of the sole can have a smiling face shape, thus being more beautiful and having ornamental value.

[0036] However, the utility model is not limited to this, the inner side member 21 and the outer side member 22 can also have different bending radii, for example, the curvature of the inner side member 21 can be greater than the curvature of the outer side member 22, so that the height of the outer side member 22 at the middle position can be higher than the height of the inner side member 21 at the middle position; vice versa. In such a case, the weight of the sole can be reduced while ensuring that the sole has sufficient support. In addition, in the case where the inner side member 21 and the outer side member 22 have different bending radii, the ratio between the minimum distance L3 between the upper surface of only one of the side members and the bottom surface of the sole and the maximum distance L4 between the upper surface of the one side member and the bottom surface of the sole can be less than or equal to 0.5, and the above-mentioned ratio between the other side member and the bottom surface of the sole can be greater than 0.5.

[0037] In addition, as shown in Figure 3 and Figure 4 To achieve better support for the forefoot, the forefoot portion can be slightly raised relative to the heel portion, and the height of the side member 20 at the front end can be lower than that at the rear end, so that the weight of the entire sole is more balanced in the front-rear direction and more ergonomic.

[0038] The width of the sole of a conventional canvas shoe at the forefoot position is usually narrow, which limits the normal movement of the foot and easily causes a squeezing feeling and discomfort, making it difficult to walk for a long time. According to the embodiments of the utility model, the ratio of the maximum width W1 of the forefoot portion of the sole to the maximum width W2 of the heel portion can be in the range of 1.33 to 1.39. In this way, by reasonably adjusting the width ratio of the forefoot and the heel, the sole provides a more spacious space for the forefoot while ensuring the stability of the heel, providing a certain stretching and movement space for the forefoot during walking, without making the shoe too large to cause poor fit, meeting the ergonomic principle, and further improving the comfort of wearing. Through experiments, the canvas shoes manufactured using the above design and width ratio relationship of the utility model can walk more than ten thousand steps without feeling tired, which can be comparable to comfortable sports shoes.

[0039] According to the embodiments of the utility model, the maximum width W1 of the forefoot portion can be located at a position corresponding to the B-B line, and the maximum width W2 of the heel portion can be located at a position corresponding to the D-D line.

[0040] In addition, the bottom member 10 of the sole can be substantially the same as the structure of a conventional sole, for example, the lower surface of the bottom member 10 can be provided with anti-slip stripes, and the upper part of the bottom member 10 can form a hollow structure to reduce the weight of the sole while maintaining the support performance, which will not be described here.

[0041] According to the embodiment of the utility model, in order to match the smiling face shape of side member 20, a plurality of smiling face patterns can be arranged on the lower surface of bottom member 10 to increase the interesting and aesthetic properties, and the anti-skid effect is also improved.

[0042] The shoe sole can be made of light materials such as new foaming materials, which have good elasticity and wear resistance. These materials not only effectively reduce the weight of the shoe sole, but also have excellent resilience, providing good support and cushioning for the feet during walking, reducing the impact force between the soles and the ground, and achieving the effect of not being tired after walking.

[0043] According to another embodiment of the utility model, a shoe can include the shoe sole as described above. The shoe can be a canvas shoe, but is not limited thereto. The shoe sole can also be used as the shoe sole of other types of shoes, for example, as the shoe sole of sports shoes.

[0044] According to the shoe sole of the utility model, the weight of the shoe sole can be reduced, the pressure on the soles can be better dispersed, and the wearing comfort can be improved. The wrapping of the feet can be improved, and sufficient stretching space can be provided for the forefoot, improving the walking endurance and achieving the effect of not being tired after walking.

[0045] The features, structures or characteristics described in the utility model can be combined in one or more embodiments in any suitable manner. In the above description, many specific details are provided to give a full understanding of the embodiments of the utility model. However, those skilled in the art will realize that the technical solutions of the utility model can be practiced without one or more of the specific details, or other methods, components, materials, etc. can be used.
