[0027] In this embodiment, the hollow layer 2 is made of a wear-resistant material, and the shock-absorbing layer 1 is made of a flexible, lightweight material. Located at the bottom of the shoe, where it frequently contacts the ground, the hollow layer 2, made of a wear-resistant material, can withstand increased friction and wear, significantly extending its service life. The shock-absorbing layer 1 primarily reduces the impact of the ground on the foot during walking. Made of a flexible material, the shock-absorbing layer 1 simultaneously reduces shock and weight, further enhancing the consumer experience.

[0028] The anti-skid structure comprises anti-skid bosses 24 and hollow holes 25, wherein the anti-skid bosses 24 are arranged on the toe part 21, the middle part 22 and the heel part 23, and the hollow holes 25 are arranged on the middle part 22 of the hollow layer 2; the anti-skid bosses 24 are arranged in multiple numbers and are arranged on the toe part 21, the middle part 22 and the heel part 23 respectively, and the surface of the anti-skid boss 24 is further provided with multiple anti-skid lines 241 arranged transversely; when people walk, the friction direction of the ground to the shoe is the same as the walking direction of people, the anti-skid lines 241 arranged transversely are perpendicular to the friction direction of the ground to the shoe, which can prevent the friction of the ground to the shoe from generating other directional components, improve the friction between the shoe and the ground in the walking direction, and further improve the anti-skid effect of the anti-skid lines 241. The hollow holes 25 are arranged in multiple numbers, have a triangular outline, are uniformly arranged on the middle part 22, and penetrate through the hollow layer 2. The hollow holes 25 increase the height difference of the one surface of the hollow layer 2 facing the ground, and when the anti-skid boss 24 is worn out, the hollow holes 25 can still provide a certain height difference for the hollow layer 2, ensure the roughness of the hollow layer 2, and improve the anti-skid effect and service life of the shoe.

[0029] In the embodiment, the anti-skid boss 24 arranged on the middle part 22 is arranged adjacent to the hollow hole 25 to form an anti-skid part, and the anti-skid part fills the middle part 22 in an array manner. The anti-skid part forms multiple parallel or staggered first anti-skid grooves 221 on the middle part 22. The first anti-skid grooves 221 improve the roughness of the middle part 22. Since the middle part 22 corresponds to the arch of the foot, the pressure of the arch on the ground is small during walking, which leads to small friction of the middle part 22 on the ground. The roughness of the middle part 22 can be improved through the first anti-skid grooves 221, which further improves the friction coefficient between the middle part 22 and the ground, improves the friction between the middle part 22 and the ground, and further improves the anti-skid effect of the middle part 22, so that the anti-skid effect of the shoe during walking is more uniform.

[0030] Specifically, the middle part 22 is provided with a buffer groove 222 on both sides, which is matched with the outline of the hollow layer 2. At least one end of the first anti-skid groove 221 communicates with the buffer groove 222. When the shoe is stepped on the accumulated water, the accumulated water will be discharged from the first anti-skid groove 221 due to the pressure of the shoe.

The buffer groove 222 makes the port of the first anti-skid groove 221 located inside the shoe sole, and when the accumulated water splashes out of the first anti-skid groove 221, the buffer groove 222 blocks part of the splashing accumulated water, which improves the anti-splashing effect of the shoe.

[0031] Specifically, the second anti-skid groove 26 is arranged between the toe part 21 and the middle part 22 and between the middle part 22 and the heel part 23, and the two ends of the second anti-skid groove 26 are communicated with the buffer groove 222; the second anti-skid groove 26 and the buffer groove 222 form a ring-shaped channel around the middle part 22, and the two ends of the first anti-skid groove 221 are communicated with the ring-shaped channel. When the two ends of the first anti-skid groove 221 are communicated with the ring-shaped channel, an additional channel is provided for the water in the first anti-skid groove 221 to drain, so that the water can be drained from multiple channels, thereby reducing the splashing effect of the water when it is drained in the first anti-skid groove 221, and further improving the anti-splashing effect of the shoes.

[0032] Specifically, the third anti-skid groove 211 is further arranged on the toe part 21, and the third anti-skid groove 211 is in an L shape, one end of which is communicated with the second anti-skid groove 26 and the other end of which is communicated with the outside. In daily walking, people usually only land on the toes due to walking habits, and the force between the ground and the shoes is concentrated on the toe part 21, while the force of the human foot on the shoes and the force between the ground and the shoes remain unchanged. However, the decrease in contact area will cause the pressure on the unit area of the toe part 21 to increase, making the toe part 21 prone to wear and tear, resulting in a decrease in the roughness of the toe part 21 and a decrease in the anti-skid effect. The third anti-skid groove 211 further improves the roughness of the toe part 21, further improves the anti-skid effect of the toe part 21, and thus improves the service life of the shoes.

[0033] Specifically, the fourth anti-skid groove 231 is further arranged on the heel part 23, and the fourth anti-skid groove 231 is in a U shape or a U-like shape, and the two ends of the fourth anti-skid groove 231 are communicated with the second anti-skid groove 26. In daily life, people usually only land on the heels due to walking habits, and the force between the ground and the shoes is concentrated on the heel part 23, while the force of the human foot on the shoes and the force between the ground and the shoes remain unchanged. However, the decrease in contact area will cause the pressure on the unit area of the heel part 23 to increase, making the heel part 23 prone to wear and tear, resulting in a decrease in the roughness of the heel part 23 and a decrease in the anti-skid effect. The fourth anti-skid groove 231 further improves the roughness of the heel part 23, further improves the anti-skid effect of the heel part 23, and thus improves the service life of the shoes.

[0034] Specifically, the depths of the first anti-skid groove 221, the second anti-skid groove 26, the third anti-skid groove 211, the fourth anti-skid groove 231 and the buffer groove 222 are equal, forming a uniform drainage channel, when the water from the bottom of the shoes is discharged, it will not be due to the height difference between the first anti-skid groove 221, the second anti-skid groove 26, the third anti-skid groove 211, the fourth anti-skid groove 231 and the buffer groove 222, and then make the process of water discharge more smooth, improve the drainage effect of the hollow layer 2, further prevent water splash.

[0035] In the embodiment, the area of the hollow hole 25 accounts for 1 / 2 of the area of the middle part of the shoe 22; the hollow hole 25 can improve the anti-skid effect of the hollow layer 2, but too many hollow holes 25 will cause the strength of the hollow layer 2 to decrease, which will shorten the service life of the hollow layer 2, and the hollow hole 25 with appropriate area can take into account the anti-skid effect and service life of the hollow layer 2.
