The heel section corresponds to the back of the foot, the arch section to the arch of the foot, and the forefoot section to the ball of the foot.

As the stride continues, the foot flattens on the ground, then the heel lifts off the ground, shifting the weight primarily to the forefoot for support. Finally, the forefoot also lifts off the ground, shifting the weight primarily to the toes. Some shoe soles have ventilation holes for breathability and heat dissipation, such as the "Shock-absorbing and Breathable Shoe Sole" in utility model patent publication number CN211747326U. However, this sole does not include ventilation for the toes, which is where most sweat occurs. Therefore, such ventilation is necessary for the toes. Summary of the Invention

[0030] The present invention will now be further described with reference to the accompanying drawings.

[0031] The forefoot breathing sole of this invention, such as Figure 1 , Figure 4 and Figure 11As shown, the shoe includes an elastic midsole 1 and an elastic outsole 2. The elastic midsole 1 and the elastic outsole 2 can be made of rubber. A breathing air chamber 5 is formed between the front part of the elastic midsole 1 and the front part of the elastic outsole 2. That is, the breathing air chamber 5 is located inside the front part of the outsole and on the lower side of the elastic midsole 1. The breathing air chamber 5 is located on the upper side of the inner surface of the elastic outsole 2. The front part of the elastic midsole 1 has a rear ventilation hole 11 for ventilation of the forefoot 991 and a front ventilation hole 12 for ventilation of the toe area 992. That is, the front ventilation hole 12 is located in front of the rear ventilation hole 11. The rear ventilation hole 11 and the front ventilation hole 12 are connected to the breathing air chamber 5. That is, the rear ventilation hole 11 and the front ventilation hole 12 penetrate the elastic midsole 1 vertically.

[0032] The working principle of the shoe sole of this invention is briefly explained below: Figure 11 As shown, during walking, after the heel 993 of the foot 99 leaves the ground, the forefoot 991 of the foot 99 takes the lead in supporting the body weight. Because the elastic midsole 1 and elastic outsole 2 of the shoe are elastic, the breathing chamber 5 is compressed. Since the forefoot 991 is located on the corresponding upper side of the rear of the breathing chamber 5, the rear ventilation hole 11 is significantly blocked or closed by the forefoot 99. Therefore, the air in the breathing chamber 5 cannot easily escape through the rear ventilation hole 11. Meanwhile, because the toe area 992... The pressure effect of the front ventilation hole 12 is relatively weak, thus forcing the air in the rear of the breathing chamber 5 forward. The air then passes through the front ventilation hole 12 and is ejected upwards to the toe area 992 of the foot 99, providing better ventilation and cooling. The ejected airflow has a strong blowing effect on the toe area 992, making the foot 99 feel cool and comfortable. Cooler toe area 992 reduces sweating, and the ejected airflow also helps with sweat evaporation, thus reducing sweating in the toe area. As the person walks, as... Figure 12As shown, the forefoot 991 leaves the ground, and the toes 992 become the primary point of contact with the ground. At this time, the pressure of the forefoot 991 on the rear ventilation hole 11 is significantly reduced, or the forefoot 991 can leave the rear ventilation hole 11. Meanwhile, the pressure of the toes 992 on the front ventilation hole 12 is significantly increased, causing the toes 992 to significantly block or close the front ventilation hole 12. As a result, air is quickly drawn into the rear of the breathing chamber 5 through the rear ventilation hole 11. The air flows through the forefoot 991, providing ventilation for the forefoot 991. Afterward, the entire foot 99 briefly leaves the ground, and the front ventilation hole 12 can also take in air, which in turn provides ventilation for the toes 992. The staggered ventilation structure of the rear ventilation hole 11 and the front ventilation hole 12 in this invention, combined with the characteristics of human walking, can avoid the situation where air in the breathing chamber 5 is difficult to expel due to the simultaneous closure of the rear ventilation hole 11 and the front ventilation hole 12. Such a situation would result in minimal ventilation. When a person is running, the heel 993 may not touch the ground for most of the time, so the breathing chamber 5 can provide better ventilation to the foot 99 according to the running situation. When a person is jumping rope, the toe part 992 may repeatedly touch the ground. When the toe part 992 touches the ground, the rear ventilation hole 11 will expel air upwards and blow air to the forefoot 991.

[0033] In some embodiments, an air damping wall 3 is provided within the breathing air chamber 5. That is, the air damping wall 3 is used to impede airflow within the breathing air chamber 5. The air damping wall 3 is located between the shoe's elastic midsole 1 and the shoe's elastic outsole 2. The air damping wall 3 is integrally connected to the shoe's elastic midsole 1 and / or the shoe's elastic outsole 2, or the air damping wall 3 is bonded to the shoe's elastic midsole 1 and / or the shoe's elastic outsole 2 using an adhesive. Figure 6 As shown, the air damping wall 3 divides the breathing air chamber 5 into several sections. When the part of the breathing air chamber 5 located on one side of the air damping wall 3 is compressed, the air needs to bypass the air damping wall 3 to flow to the other side of the breathing air chamber 5 located on the corresponding side of the air damping wall 3. In other words, the air damping wall 3 hinders the air flow between the above-mentioned sections, causing the air in the compressed part to be discharged slowly, so that the air in the compressed part plays a certain role in supporting the foot 99. The air in the compressed part provides support and shock absorption for the foot 99, and the air damping wall 3 also provides elastic support for the foot 99.

[0034] In some embodiments, such as Figure 3As shown, the breathing air chamber 5 is divided into several wedge-shaped airways 501 by the air damping wall 3. The wedge-shaped airways 501 extend longitudinally (that is, roughly in the front-back direction). One end of the wedge-shaped airway 501 forms a constricted end 5011, and the corresponding other end of the wedge-shaped airway 501 forms a flared end 5012. The front ventilation hole 12 and the rear ventilation hole 11 are respectively located in the constricted end 5011, that is to say, the wedge-shaped airway 501 is either narrow at the front and wide at the back or wide at the front and narrow at the back (in... Figure 3 (From the visual direction), the wedge-shaped air passage 501 gradually narrows from the flared end 5012 to the constricted end 5011. Therefore, when the flared end 5012 is compressed vertically, and the compression gradually shifts towards the constricted end 5011, the air within the wedge-shaped air passage 501 is forced towards the constricted end 5011. As the air flows towards the constricted end 5011, the wedge-shaped air passage 501 acts as a converging airflow. The increasing compression intensity of the airflow through the wedge-shaped air passage 501 leads to increased airflow pressure. The higher-pressure air is then discharged through the front ventilation hole 12 or the rear ventilation hole 11, increasing the blowing intensity. The air jet ejected upwards from the front ventilation hole 12 or the rear ventilation hole 11 will... The adhesive action removes air from the area surrounding the air jet, causing a drop in air pressure in that area. This attracts air from the area surrounding the front or rear ventilation holes 12 on the upper side of the shoe's elastic midsole 1, creating a supplementary airflow. This supplementary airflow flows over the bottom of the foot 99, resulting in better ventilation. In other words, the wedge-shaped air passage 501 converges the airflow, causing the front or rear ventilation holes 12 to eject a stronger airflow, thus creating a stronger supplementary airflow. Since the base of the toes tends to sweat, the supplementary airflow formed on the upper side of the area surrounding the front ventilation hole 12 helps reduce sweating in this area, which is beneficial to the health of the foot 99. The compression of the wedge-shaped air passage 501 is not limited to normal walking. When a person jumps, the toes 992 land first, followed by the forefoot 991, or when walking on a rugged mountain path, causing the breathing chamber 5 to be subjected to various actual compression situations.

[0035] Furthermore, such as Figure 3As shown, there are two air damping walls 3, with the distance between the two walls gradually increasing from back to front. These two walls divide the breathing chamber 5 into three main sections, meaning there are three wedge-shaped airways 501: left, middle, and right. Two front ventilation holes 12 are located at the front ends of the left and right wedge-shaped airways 501, and a rear ventilation hole 11 is located at the rear end of the middle wedge-shaped airway 501. When a person walks, the forefoot 991 lands first, and the air in the left and right wedge-shaped airways 501 is then forced towards the corresponding front ventilation holes 12. The combined effect of the two front ventilation holes 12 provides a larger airflow to the toe area 992, enhancing ventilation. In some cases, when a person jumps, the toe area 992 lands first, followed by the forefoot 991 primarily supporting the body, causing the air in the middle wedge-shaped airway 501 to be forced backward towards the corresponding rear ventilation hole 11.

[0036] In some embodiments, such as Figure 3 As shown, both longitudinal ends (i.e., the front and rear ends) of the wedge-shaped air passage 501 are closed ends. For example, the rear end of the air damping wall 3 is connected to the partition wall 4, and the front end of the air damping wall 3 is connected to the side wall of the sealing groove 201. That is, the adjacent wedge-shaped air passages 501 are separated from each other. So when the flared end 5012 is squeezed in the vertical direction, the air in the flared end 5012 of the wedge-shaped air passage 501 is forced to be discharged through the front ventilation hole 12 or the rear ventilation hole 11, which can greatly reduce the leakage and facilitate the ejection of a stronger airflow from the front ventilation hole 12 or the rear ventilation hole 11.

[0037] like Figure 8 As shown, in some embodiments, each wedge-shaped airway 501 can also be interconnected, that is, each wedge-shaped airway 501 is connected to the breathing air chamber 5, so that the air in the breathing air chamber 5 can flexibly flow between each wedge-shaped airway 501.

[0038] In some embodiments, such as Figure 8 As shown, the number of air damping walls 3 is set to two, and the distance between the two air damping walls 3 on the left and right is set to gradually increase from front to back. Therefore, when a person jumps, the toes 992 land first and then the forefoot 991 lands. The two rear ventilation holes 11 on the left and right are combined to enhance the ventilation effect on the forefoot 991.

[0039] In some embodiments, such as Figure 6As shown, the number of air damping walls 3 is set to one, and the air damping walls 3 are arranged to extend longitudinally. That is to say, the breathing air chamber 5 is divided into two sections, left and right, by the air damping walls 3. The left and right sides of the air damping walls 3 are respectively provided with front ventilation holes 12 and rear ventilation holes 11. Therefore, when the breathing air chamber 5 is compressed on one side in the left and right direction, and the compression is gradual from back to front or from front to back, since the air damping walls 3 can prevent air from flowing directly to the corresponding other side in the left and right direction, the front ventilation hole 12 or rear ventilation hole 11 corresponding to the specific compressed side of the breathing air chamber 5 can also have a strong airflow.

[0040] In some embodiments, such as Figure 7 As shown, the air damping wall 3 extends laterally (i.e., it extends roughly in the left-right direction). The number of air damping walls 3 can be set to one. The front ventilation hole 12 is located on the front side of the air damping wall 3, and the rear ventilation hole 11 is located on the rear side of the air damping wall 3. The air damping wall 3 forms a ventilation gap 301. So, during the process of the forefoot 991 landing and then the toe part 992 landing, the air in the breathing air chamber 5 flows forward. The air is obstructed by the air damping wall 3. At this time, the air in the part of the breathing air chamber 5 located on the rear side of the air damping wall 3 provides better support and shock absorption for the forefoot 991. Subsequently, the air flows through the ventilation gap 301 to the front side of the air damping wall 3, and then the air is discharged through the front ventilation hole 12.

[0041] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, a partition wall 4 is provided between the middle of the elastic midsole 1 and the middle of the elastic outsole 2. The partition wall 4 is located on the rear side of the breathing air chamber 5. In other words, the partition wall 4 divides the cavity between the elastic midsole 1 and the elastic outsole 2 into front and rear parts. The position of the partition wall 4 corresponds to the arch of the foot 99. The partition wall 4 provides a certain support for the human arch.

[0042] In some embodiments, such as Figure 4 As shown, a rear air chamber 7 is formed between the rear part of the shoe's elastic midsole 1 and the rear part of the shoe's elastic outsole 2, and a partition wall 4 is located on the front side of the rear air chamber 7, as shown. Figure 9 and Figure 10As shown, a ventilation groove 202 is formed between the front part of the shoe's elastic midsole 1 and the front part of the shoe's elastic outsole 2. The groove wall of the ventilation groove 202 is integrated with the shoe's elastic outsole 2. The ventilation groove 202 is located on one side of the breathing air chamber 5 in the left-right direction. The front end of the ventilation groove 202 is connected to the front end of the breathing air chamber 5, and the rear end of the ventilation groove 202 is connected to the front end of the rear air chamber 7. Specifically, a partition wall notch 401 is formed at one end of the partition wall 4 in the left-right direction. The rear end of the ventilation groove 202 is located at the partition wall notch 401. (In the front-back direction) the partition wall 4 is located between the heel part 21 and the forefoot part 22 of the outsole of the shoe's elastic outsole 2. (In the vertical direction) the breathing air chamber 5 is specifically located between the forefoot part 22 of the outsole and the front part of the shoe's elastic midsole 1. Therefore, when a person walks, the heel... When the heel 993 lands first, the rear air chamber 7 is compressed. As a result, the air in the rear air chamber 7 is forced forward through the ventilation channel 202 into the breathing air chamber 5. Since the front end of the ventilation channel 202 is connected to the front end of the breathing air chamber 5, the air resistance of the ventilation channel 202 is relatively large. In fact, the air in the rear air chamber 7 is not easily discharged into the breathing air chamber 5. Therefore, the air in the rear air chamber 7 provides a certain degree of support and shock absorption for the heel 993. The air that is forced into the front end of the breathing air chamber 5 is then discharged through the front ventilation hole 12, which provides ventilation for the toe area 992. After that, the ball of the foot 991 lands. Due to the large air resistance of the ventilation channel 202, the air is not easily flowed back into the rear air chamber 7. Therefore, the front ventilation hole 12 can still blow air upward, so that the front ventilation hole 12 can blow air into the toe area 992 twice.

[0043] Furthermore, the partition wall 4 is integrated with the shoe's elastic midsole 1 and / or elastic outsole 2, which helps to prevent the partition wall 4 from easily shifting. For example, if... Figure 2 As shown, the lower end of the partition wall 4 is integrated with the inner surface of the shoe elastic outsole 2. Since the shoe elastic outsole 2 indirectly supports the foot 99 through the shoe elastic midsole 1, the foot 99 is relatively easy to rub the shoe elastic midsole 1 horizontally (the shoe elastic midsole 1 elastically deforms). Therefore, by molding the partition wall 4 and the shoe elastic outsole 2 as a single piece, the partition wall 4 becomes relatively more stable.

[0044] like Figure 5 and Figure 9 As shown, for example, the periphery of the shoe's elastic outsole 2 has a sealing groove 201, such as... Figure 5 As shown, the periphery of the shoe's elastic midsole 1 has a downwardly protruding edge tenon 13, which is adapted to fit an insert sealing groove 201. The sealing groove 201 is bonded to the edge tenon 13. For example, as... Figure 3 and Figure 5 As shown, an elastic support column 14 is formed on the lower side of the shoe's elastic midsole 1, and the lower end of the elastic support column 14 abuts against the inner surface of the shoe's elastic outsole 2, as shown. Figure 3As shown, the elastic support column 14 is staggered with the rear ventilation hole 11 and the front ventilation hole 12.

[0045] In some embodiments, such as Figure 13 As shown, a rear air chamber 7 is formed between the rear part of the shoe's elastic midsole 1 and the rear part of the shoe's elastic outsole 2. A partition wall 4 is located in front of the rear air chamber 7. A ventilation groove 202 is formed between the front part of the shoe's elastic midsole 1 and the front part of the shoe's elastic outsole 2. The groove wall of the ventilation groove 202 is integrated with the shoe's elastic outsole 2. The ventilation groove 202 is located on one side of the breathing air chamber 5 in the left-right direction. The front end of the ventilation groove 202 connects to the front end of the breathing air chamber 5, and the rear end of the ventilation groove 202 connects to the front end of the rear air chamber 7. Figure 13 As shown, the breathing air chamber 5 is provided with anterior and posterior partition walls 51 and toe airway walls 52. The anterior and posterior partition walls 51 are located in the middle of the breathing air chamber 5 in the anterior-posterior direction. Thus, the breathing air chamber 5 is divided by the anterior and posterior partition walls 51 into a forepaw rear air chamber 502 and an anterior mouth air chamber 503. The anterior mouth air chamber 503 is located in front of the forepaw rear air chamber 502. The left rear end of the anterior mouth air chamber 503 corresponds to the left front end of the forepaw rear air chamber 502, and the right rear end of the anterior mouth air chamber 503 corresponds to the right front end of the forepaw rear air chamber 502. The toe airway walls 52 extend roughly in the anterior-posterior direction and are located in front of the anterior and posterior partition walls 51. That is to say, the toe airway walls 52 are located in the anterior mouth air chamber 503. The anterior mouth air chamber 503 is divided into three toe-shaped airways 5031 by the two toe airway walls 52. That is to say, the three toe-shaped airways 5031 are distributed in the left-right direction. Figure 13 As shown, the elastic midsole 1 of the shoe has a rear ventilation hole 11 at the corresponding position of the air chamber 502 in the rear area of ​​the forefoot, a front ventilation hole 12 at the corresponding position of the front end of the toe air passage 5031, and a rear ventilation hole 15 of the toe air passage at the corresponding position of the rear end of the toe air passage 5031. Therefore, when the heel 993 lands, the air in the rear air chamber 7 is discharged through the ventilation groove 202 to the front end of the forefoot air chamber 503, and then discharged upward through the front ventilation hole 12; when the forefoot rear air chamber 502 is compressed in the vertical direction (for example, when stepping on a protrusion on the ground), the air in the forefoot rear air chamber 502 is squeezed into the forefoot air chamber 503, and then the air is discharged upward through the front ventilation hole 12; when the rear end of the toe air channel 5031 is compressed in the vertical direction, the air in the rear part of the toe air channel 5031 is squeezed out to the front ventilation hole 12; when the front end of the toe air channel 5031 is compressed in the vertical direction, the air in the front part of the toe air channel 5031 is squeezed out to the rear ventilation hole 11; thus, when the sole is partially compressed, it produces an effective blowing effect on the foot 99.

[0046] The shoes of this invention, such as Figure 11As shown, the shoe includes the forefoot breathable sole described above. The forefoot breathable sole is provided with a shoe body 6, and a shoe wearing cavity is formed inside the shoe body 6. The foot 99 can be inserted into the wearing cavity of the shoe body 6. For example, the lower end of the shoe body 6 is bonded to the upper edge of the sole of the present invention. Since the shoe of the present invention is provided with the sole of the present invention, the shoe of the present invention is beneficial to reducing sweating in the toe area.
