Description

Technical Field

[0001] This utility model relates to a shoe sole, and more particularly to a four-way flexible EVA shoe sole. Background Technology

[0002] Shoes are necessities, and people's demands for foot comfort have increased. The sole, as a crucial component of a shoe, is a key factor affecting wearing comfort, and its softness is a significant indicator of comfort. However, many existing soles are relatively stiff, resulting in low comfort when worn. To improve sole comfort, some existing soles have undergone modifications. For example, patent application number 201610383490.7 discloses a biomimetic grip and anti-slip sole, which adds flex grooves to facilitate forward and backward bending, improving the sole's softness. However, with the flex grooves, debris such as pebbles can easily get stuck in them during walking, affecting comfort to some extent. Summary of the Invention

[0003] The purpose of this invention is to provide a four-way flexible EVA sole that can solve at least one of the above problems.

[0004] According to one aspect of the present invention, a four-way flexible EVA sole is provided, including a body, the bottom of the body is provided with a first cut and a second cut, the first cut and the second cut are arranged intersectingly, and the middle part of the body is provided with a plurality of squares, the opposite sides of the squares are the first cuts, and the other two sides are the second cuts.

[0005] The beneficial effects of this utility model are as follows: by providing a first cut and a second cut, and forming corresponding blocks through the first cut and the second cut, with the first cut and the second cut corresponding on each side of the block, it is convenient for the body to bend along the direction of the first cut and the second cut, thus improving flexibility and greatly improving the comfort of wearing the sole; at the same time, by providing the first cut and the second cut, the gap between the two side walls of the cut is greatly reduced, greatly reducing the possibility of foreign objects such as gravel getting stuck in the cuts, and improving the comfort of using the body.

[0006] In some embodiments, multiple first cuts are made along the length of the body, and multiple second cuts are made along the width of the body. This facilitates bending of the entire body in the corresponding directions, improving the overall flexibility of the sole.

[0007] In some embodiments, the two ends of the first cut extend through both sides of the body. This allows the entire sole to bend along the transverse direction of the body, i.e., the width direction, increasing the degree of flexibility and thus improving the overall bending performance of the sole.

[0008] In some embodiments, the depth of the first cut is 3-6 mm, and the depth of the second cut is 3-6 mm. This depth satisfies the bending requirements of the shoe sole and effectively prevents foreign objects such as gravel from getting stuck in the cuts.

[0009] In some embodiments, the body also has a third and a fourth cut. The first and second cuts are angled, with the angles of the first and second cuts opposite. One end of the first cut intersects with one end of the corresponding second cut at the third cut, and the other end of the first cut intersects with the other end of the corresponding second cut at the fourth cut. The third cut extends through one side of the body, and the fourth cut extends through the other side. This satisfies the distribution requirements of different shoe sole cuts, facilitates lateral and longitudinal bending of the sole, greatly improves bending performance, and enhances wearing comfort.

[0010] In some embodiments, both the third and fourth cuts are horizontally positioned and distributed along the length of the body. This allows for bending at each corresponding location on the body.

[0011] In some implementations, the depth of the third and fourth cuts is 3-6 mm. This depth satisfies the bending requirements of the sole and effectively prevents foreign objects such as gravel from getting stuck in the cuts. Attached Figure Description

[0012] Figure 1 This is a structural schematic diagram of a four-way flexible EVA shoe sole according to the present invention; Figure 2 This is a structural schematic diagram of one embodiment of a four-way flexible EVA shoe sole according to the present invention; Figure 3 This is a schematic diagram of another embodiment of a four-way flexible EVA shoe sole according to the present invention. Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings.

[0014] Reference Figures 1-2A four-way flexible EVA sole includes a body 1. The bottom of the body 1 has a first cut 11 and a second cut 12, which are intersecting. The middle of the body 1 has multiple squares 13, with the first cut 11 on one side and the second cut 12 on the other. The sole is made of EVA (ethylene-vinyl acetate copolymer), which increases its elasticity and softness. Both the first and second cuts 11 are formed by pressing downwards with a high-temperature blade, resulting in small gaps. When the body 1 is compressed, the cuts remain seamless. When the body 1 is not subjected to external force and is in a natural state, the gaps between the cuts are 0.2~0.5mm, significantly reducing the risk of gravel getting stuck in the cuts.

[0015] By providing a first cut 11 and a second cut 12, the sole can bend along the direction of the first cut 11 and the second cut 12 when worn, which facilitates multi-directional bending of the sole and greatly improves the comfort of the sole during use.

[0016] like Figure 1 and Figure 2 As shown, in one embodiment, multiple first cuts 11 are provided along the length direction of the body 1, and multiple second cuts 12 are provided along the width direction of the body 1.

[0017] The first cut 11 extends through both sides of the main body 1.

[0018] The depth of the first cut 11 is 3~6mm, and the depth of the second cut 12 is 3~6mm. Therefore, by setting the depth of each cut, the bending requirements of the body 1 along each cut can be met, and at the same time, it can effectively prevent foreign objects such as gravel from getting stuck in each cut 11.

[0019] Therefore, the first horizontal cut 11 and the second vertical cut 12 allow the body 1 to bend easily in the forward, backward, left and right directions, achieving multi-directional bending and thus improving the softness and comfort of the sole.

[0020] like Figure 3 As shown, in another embodiment, the body 1 is further provided with a third cut 14 and a fourth cut 15. The first cut 11 is inclined and the second cut 12 is inclined. The inclination directions of the first cut 11 and the second cut 12 are opposite. One end of the first cut 11 and one end of the corresponding second cut 12 intersect at the third cut 14. The other end of the first cut 11 and the other end of the corresponding second cut 12 intersect at the fourth cut 15. The third cut 14 penetrates one side of the body 1 and the fourth cut 15 penetrates the other side of the body 1.

[0021] In this embodiment, the body 1 can also be bent along the direction of the first cut 11 and the second cut 12 to achieve the multi-directional bending function of the sole.

[0022] Both the third cut 14 and the fourth cut 15 are horizontally positioned and distributed along the length of the main body 1. Furthermore, the depth of both the third cut 14 and the fourth cut 15 is 3-6 mm.

[0023] By providing a third cut 14 and a fourth cut 15, the bottom of the entire body 1 can be bent along the third cut 14 and the fourth cut 15, increasing the range of bending of the sole.

[0024] The four-way flexible EVA sole of this invention, by having a first cut 11 and a second cut 12 in different directions, can achieve bending of the body 1 in different directions, which greatly improves the bending performance of the entire sole and thus improves the comfort of wearing the sole.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
