In modern times, most shoes are composed of a midsole made of foam material and an upper that wraps the foot and is sewn on the midsole. A layer of outsole is installed under the midsole to improve wear resistance and grip. The shoes are tied to the user's feet with the strap system on the upper. They are light and durable. Sports shoes are a type of shoe. With a better shock-absorbing midsole and a stronger grip outsole, the shoes are more suitable for exercise when worn, effectively relieving foot fatigue caused by exercise and preventing sports injuries to a certain extent.

When in use, the outsole 1 is formed at one time, and the upper layer 2 is sewn to the outsole 1 by bonding and sewing. The outsole 1 can be made of wear-resistant rubber material to greatly improve its wear resistance. Subsequently, through the foaming molding technology, the low-density foam body 32 is first filled in the mold for one-time foaming, and the high-density foam body 3 is filled in other positions of the mold. 1 raw material, and secondary foaming is performed to form a midsole body 111, and then the midsole is inserted from the wearing opening 3 to form a sports shoe body. After a period of use, if the midsole body 111 decays, since the midsole body 111 is manufactured and assembled separately from the outsole 1, the midsole body 111 can be taken out from the wearing opening 3 by pulling and replaced, so that the high shock-absorbing performance of the midsole body 111 can be maintained at all times, and the shock-absorbing effect of the sports shoe can be affected by the attenuation of the midsole body 111 and the inability to replace it. At the same time, a low-density foam body 32 is formed on the dual-density disassembled midsole 11 according to the force points and force points of the human foot, namely the heel and metatarsal positions, and a high-density foam body 31 is formed at other positions. One midsole has two different densities.The low-density foam 32 is easy to deform and absorb shock to achieve efficient shock absorption at the force points and force generating points of the foot. At the same time, the high-density foam 31 at other positions is used to provide auxiliary shock absorption and improve the overall rigidity of the midsole body 111. The high-density foam 31 is not easy to decay to improve the service life of the midsole body 111. While improving the service life of the midsole body 111, the foot is subjected to differentiated shock absorption, which greatly improves the shock absorption effect. At the same time, when worn, the inner layer 42 of the three-layer structure of the upper layer 2 provides high contact comfort through the soft adhesion and sweat-wicking characteristics of its Lycra spandex core-spun yarn, and cooperates with the side tensile and breathable layer 43 composed of multiple weaving units to greatly improve the lateral tensile performance of the upper. The longitudinal yarn 431 is extended and distributed along the side of the upper. It is not folded, has poor extensibility, is not easy to deform when subjected to force, can fully hold the foot, and cooperates with the curved longitudinal yarn 432. The shoe is preferably woven with TPU yarn, and the first transverse yarn 433 and the second transverse yarn 434 in the forward direction are staggered and folded between the two longitudinal yarn groups, so that they can be deformed and stretched when being pulled forward, and then in the process of lateral pushing during exercise, the longitudinal yarn group can fully resist the lateral force, and it is not easy to produce excessive deformation and cause rollover, so that the safety during lateral movement is greatly improved. At the same time, it can be deformed during positive extrusion, and then when moving forward and braking suddenly, the stretching knot 435 can be deformed by the pulling force to stretch the upper, absorb pressure, and prevent the toe from hitting the toe during the sudden braking process of exercise, so that the wearing wrapping and safety are improved. At the same time, the air permeable hole 44 cooperates with the air permeable cavity 436 to provide extremely high breathability when wearing, so that the feet are not easy to be stuffy, and the wearing comfort is effectively guaranteed;,

[0031] The side of the outsole 1 at the forefoot position is provided with a forefoot stabilizing piece 6 made of TPU material, which covers the edge of the upper layer 2; the edge of the outsole 1 at the heel position is provided with a heel stabilizing piece 7 made of TPU material, which covers the edge of the upper layer 2; the upper layer 2 at the side of the forefoot of the foot is provided with an upper stabilizing piece 10; the forefoot stabilizing piece 6 is used to provide anti-rollover performance when the forefoot pushes the ground sideways, and the phenomenon of the outer sole 1 curling and spraining the foot is not easy to occur; at the same time, the heel stabilizing piece 7 is used to make the stability of the heel landing after jumping stronger, and it is not easy to roll over; and the upper stabilizing piece 10 is used to further improve the lateral force resistance of the upper layer 2, so that the upper layer 2 has stronger wrapping and stability when worn;

[0032] The upper surface of the shoe upper layer 2 is sewn with a shoe tongue 4 extending toward the wearing opening 3, and the shoe upper layer 2 is tied with a shoe lace 5 located on the upper surface of the shoe tongue 4 and passing through the shoe tongue 4, which is conducive to generating downward pressure on the top surface of the shoe through the shoe tongue 4 and the shoe lace 5, thereby being able to more fully squeeze and wrap the foot that is inserted into the shoe;

[0033] The upper surface of the upper layer 2 at the forefoot position is provided with a forefoot hot-pressing layer 8, and the side surface of the upper layer 2 is provided with a side hot-pressing layer 9, which is beneficial to prevent the foot from being stepped on by the forefoot hot-pressing layer 8, enhance the rigidity of the upper layer 2, and further improve the resistance of the upper layer 2 to lateral force by the side hot-pressing layer 9, and further prevent the upper layer 2 from rolling over when stepping on the ground;

[0034] The dual-density detachable midsole 11 further includes an upper enveloping body 113 extending upwardly along the midsole body 111 and integrally formed with the midsole body 111. The upper enveloping body 113 is integrally formed with a V-shaped bending groove 115 at the bending position of the forefoot, which is conducive to better wrapping the midsole body 111 around the foot through the upper enveloping body 113, resisting and blocking the foot from sliding, thereby making the wearing wrapping feel better and less prone to sliding. At the same time, the bending groove 115 makes bending easier during movement and reduces the foreign body sensation.

[0035] The bottom surface of the midsole body 111 is provided with a honeycomb anti-skid groove 114. The midsole body 111 is located at the position of the metatarsal bone of the forefoot and is also penetrated and embedded with an adsorption buffer block 116. The adsorption buffer block 116 includes two symmetrically distributed adsorption airbag blocks with opposite upper and lower surfaces. An elastic plate 55 is provided between the two adsorption airbag blocks. A deformation cavity 56 is formed between the two adsorption airbag blocks and the elastic plate 55. The adsorption airbag block includes an airbag body 52 with an inner cavity filled with inert gas and a suction tube 51 penetrating the airbag body 52. ​​Two symmetrically distributed fiber sheets 53 are fixed on the upper and lower surfaces of the inner cavity of the airbag body 52. ​​The two fiber sheets 53 are fixed on the upper and lower surfaces of the inner cavity of the airbag body 52. A plurality of intersecting fiber filaments 54 are arranged between the fiber sheets 53, and a deformed slot is arranged on the inner wall of the airbag body 52 on the side wall of the suction tube 51. The suction tube 51 includes an extrusion chamber 511 and an exhaust pipe 512 arranged at the end of the extrusion chamber 511 and connected to the extrusion chamber 511. An exhaust groove 514 is formed integrally on the inner wall of the exhaust pipe 512. A lifting rod 515 is slidingly arranged on the inner wall of the exhaust pipe 512. A closing plate 516 that fits the top of the exhaust groove 514 is arranged on the side wall of the lifting rod 515. A convex block is arranged on the inner wall of the extrusion chamber 511. An elastic member 517 is arranged between the bottom surface of the convex block and the top of the lifting rod 515. The anti-slip The groove 114 increases the friction between the midsole body 111 and the inner surface of the outer sole 1, further preventing the midsole body 111 from sliding when worn. At the same time, an adsorption buffer block 116 is penetrated and set at the stepping position of the midsole body 111. When stepping, the downward pressure squeezes the adsorption airbag block, causing the airbag body 52 to deform and absorb pressure and impact, thereby improving the buffering performance. With the fiber filament 54, the deformation of the airbag body 52 is more controllable. At the same time, when stepping, two symmetrically distributed adsorption airbag blocks with opposite upper and lower surfaces are deformed at the same time, thereby deforming the extrusion cavity 511 of the suction tube 51, and causing the gas to flow downward, so that the gas pushes the closing plate 516 open, so that the lifting The lowering rod 515 descends and stretches the elastic member 517, thereby allowing the gas to be discharged from the exhaust pipe 512. At this time, the air pressure in the extrusion chamber 511 can generate an air pressure difference with the outside. At the same time, the elastic force of the elastic member 517 pushes the lifting rod 515 back to reset it and close the exhaust groove 514 through the closing plate 516, thereby generating suction at the opening of the extrusion chamber 511, thereby adsorbing the foot. At the same time, another suction pipe adsorbs the inner surface of the outsole, thereby greatly improving the anti-slip effect of the foot and the dual-density detachable midsole 11, and greatly improving the fixing effect of the outsole 1 and the dual-density detachable midsole 11. It is not easy to slip when wearing it for intense exercise, and it is safer;

[0036] The bottom surface of the midsole body 111 is provided with an anti-torsion device, which includes a nylon anti-torsion plate 21 located at the arch position of the human foot and an extension plate 22 arranged on the top of the anti-torsion plate 21. The extension plate 22 extends from the heel to the forefoot to the metatarsal position of the forefoot and bends to pass through the edge of the midsole body 111. A plurality of deformation holes 23 are penetrated through the extension plate 22, and a plurality of semicircular deformation grooves 24 are provided at the edge of the extension plate 22. The anti-torsion plate 21 improves the anti-twisting performance of the midsole body 111, so that the sports shoe has better rigidity and is less likely to cause sprains. At the same time, the extension plate 22 is deformed to generate elastic force during running, thereby obtaining a boost force, making the running force more direct. The deformation holes 23 and the deformation grooves 24 are used to prevent the extension plate 22 from affecting the force deformation of the midsole body 111, thereby ensuring the buffering performance of the midsole body 111.

[0037] The two side edges of the anti-torsion plate 21 are folded upward and cover the side walls of the midsole body 111. The anti-torsion plate 21 is also provided with X-shaped reinforcing ribs 25, which are beneficial for the anti-torsion plate 21 to extend upward and support the arch of the foot, making the arch of the foot less prone to soreness when worn. The reinforcing ribs 25 further improve the rigidity of the anti-torsion plate 21 and the torsion resistance.

[0038] Working principle of the present invention: When the present invention is used, the outsole 1 is formed at one time, and the upper layer 2 is sewn on the outsole 1 by bonding and sewing. The outsole 1 can be made of wear-resistant rubber material to greatly improve its wear resistance. Then, through the foaming molding technology, a low-density foam body 32 is first filled in the mold for a first foaming, and a high-density foam body 31 raw material is filled in other positions of the mold, and a second foaming is performed to form a midsole body 111. Then, the midsole is inserted from the wearing opening 3 to form the sports shoe body. After a period of use, if the midsole body 111 is attenuated, since the midsole body 111 is manufactured and assembled separately from the outsole 1, the midsole can be pulled out. The main body 111 is taken out from the wearing opening 3 and replaced, so that the high shock-absorbing performance of the midsole main body 111 can be maintained at all times, and the shock-absorbing effect of the sports shoes is affected by the attenuation of the midsole main body 111 and the inability to replace it. At the same time, a low-density foam body 32 is formed on the double-density disassembled midsole 11 according to the force points and force points of the human foot, namely the heel and metatarsal bones, and a high-density foam body 31 is formed at other positions. Two different densities of one midsole are used. The low-density foam body 32 is easy to deform and absorb shock to achieve efficient shock absorption at the force points and force points of the foot. At the same time, the high-density foam body 31 at other positions is used to provide auxiliary shock absorption and improve the overall rigidity of the midsole main body 111, and cooperate with the high-density foam body 31. The foam body 31 is not easy to decay to increase the service life of the midsole body 111. While increasing the service life of the midsole body 111, the foot is cushioned and the cushioning effect is greatly improved. At the same time, when worn, the inner layer 42 of the three-layer structure of the upper layer 2 provides high contact comfort through the soft adhesion and sweat-wicking characteristics of its Lycra spandex core-spun yarn, and cooperates with the side tensile and breathable layer 43 composed of multiple weaving units to greatly improve the lateral tensile performance of the upper. The longitudinal yarn 431 is extended and distributed along the side of the upper. It is not folded and has poor extensibility. It is preferably woven with TPU yarn, and the first transverse yarn 433 and the second transverse yarn 434 in the forward direction are between the two longitudinal yarn groups. The shoe upper 430 is staggered and folded in an interlaced manner, so that it can be deformed and stretched when it is pulled forward. When pushing the ground sideways during exercise, the longitudinal yarn group can fully resist the lateral force, and it is not easy to produce excessive deformation and cause rollover, which greatly improves the safety during lateral exercise. At the same time, it can be deformed when it is squeezed in the forward direction. When moving forward and braking suddenly, the stretching knot 435 can be deformed by the pulling force to stretch the shoe upper and absorb the pressure to prevent the toe-touching phenomenon during the sudden braking of exercise. The wearing wrapping and safety are improved. At the same time, when worn, the air holes 44 cooperate with the air cavity 436 to provide extremely high breathability, which is not easy to make the feet stuffy and effectively ensures the wearing comfort.
