Description

Technical Field

[0001] This utility model relates to the field of shoe sole technology, and in particular to a breathable and shock-absorbing shoe sole. Background Technology

[0002] Traditional shoe soles have shortcomings in shock absorption and breathability. For example, athletic or casual shoes typically rely on foam materials for shock absorption, but these materials are prone to aging after long-term use, reducing their shock absorption effectiveness. Simultaneously, poor breathability leads to hot and damp feet, affecting comfort. While some breathable shoe designs exist, they often rely on simple ventilation holes, resulting in poor airflow circulation. Furthermore, the shock-absorbing and breathable structures are not tightly integrated, failing to achieve efficient shock absorption and breathability. Therefore, a sole structure that can simultaneously optimize both shock absorption and breathability is needed. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a breathable and shock-absorbing shoe sole to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a breathable and shock-absorbing shoe sole, comprising a midsole and an outsole. The bottom of the midsole has a forefoot groove at the forefoot and a rearfoot groove at the heel. A connecting groove is provided between the forefoot and rearfoot grooves. The bottom of the rearfoot groove also has a recessed air chamber with a sinker structure. The bottom of the air chamber has a ventilation hole penetrating the midsole. The bottom of the forefoot groove has multiple forefoot ventilation holes penetrating the midsole. A forefoot shock absorber is embedded in the forefoot groove, and a rearfoot shock absorber is embedded in the rearfoot groove.

[0005] Furthermore, the bottoms of the forefoot groove and the connecting groove are located on the same plane, and the depth of both is greater than the depth of the rearfoot groove.

[0006] Furthermore, the midsole has a heel protrusion at the corresponding air chamber position, and a flow guide groove is provided at the rear end of the heel protrusion, so that a foot-feeding island is formed in the middle of the flow guide groove. The ventilation hole is provided on the foot-feeding island, and a fan-shaped flow guide protrusion is provided around the ventilation hole at the top of the foot-feeding island.

[0007] Furthermore, the surface of the midsole is provided with a plurality of recessed holes at intervals at the heel position.

[0008] Furthermore, the bottom of the insole has recesses on both sides of the connecting groove, and the outsole has fitting protrusions at the corresponding positions of the recesses.

[0009] Furthermore, the bottom of the outer side of the insole is provided with a circumferential inner groove, and the top of the circumferential inner groove is provided with multiple slots at intervals. The edge of the outsole is provided with a circumferential edging that matches the structure of the circumferential inner groove, and the top of the circumferential edging is provided with multiple locking blocks that match and engage with the slots at intervals.

[0010] Furthermore, the bottom of the outsole has multiple forefoot protrusions spaced along its length at the forefoot position, and multiple forefoot edge protrusions are respectively provided on both sides of the forefoot protrusions; the bottom of the outsole has multiple heel protrusions spaced along its length at the heel position, and multiple heel edge protrusions are respectively provided on both sides of the heel protrusions; the bottom of the outsole has a toe protrusion; the bottom of the outsole has a heel protrusion.

[0011] Furthermore, the outsole surface is provided with an edge groove assembly corresponding to the position of the forefoot edge protrusion, the outsole surface is provided with a forefoot groove assembly corresponding to the position of the forefoot protrusion, and the outsole surface is provided with a rearfoot groove assembly corresponding to the position of the rearfoot protrusion. Beneficial effects

[0012] Compared with the prior art, the present invention has at least the following advantages: 1. The forefoot and heel shock absorbers are embedded in the grooves on the forefoot and heel respectively, combined with connecting grooves and air chamber structures, to absorb impact during pedaling and reduce foot fatigue. Rearfoot recessed holes provide additional cushioning.

[0013] 2. The air chamber, ventilation holes, and forefoot ventilation holes, together with the heel sole groove, connecting groove, forefoot sole groove, and perforated foam, form an airflow channel. When stepped on, the air chamber is compressed, and the main airflow passes through the heel sole groove, connecting groove, forefoot sole groove, and foam pores, and is discharged from the forefoot ventilation hole, with only a small amount of residual gas escaping through the ventilation hole. When released, the air chamber rebounds, creating negative pressure, and the main airflow is drawn in from the forefoot ventilation hole in the opposite direction, passing through the forefoot sole groove, connecting groove, heel sole groove, and heel shock absorber pores to refill the air chamber. At the same time, dry air from inside the shoe is drawn in through the ventilation holes to assist in the refilling, ultimately achieving a breathing effect.

[0014] 3. The circumferential inner groove of the midsole matches the circumferential edge of the outsole, and is engaged by slots and blocks to ensure the stability of the connection structure between the midsole and the outsole.

[0015] 4. The interlocking protrusions and recesses provide positioning for the outsole and midsole, and increase the contact area between them. The combination of protrusions and grooves on the sole enhances grip and flexibility. Attached Figure Description

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0026] A type of breathable, shock-absorbing sole, such as Figures 1 to 6 As shown, the outsole includes a midsole 3 and an outsole 1. The bottom of the midsole 3 has a forefoot groove 12 at the forefoot and a rearfoot groove 14 at the heel. A connecting groove 13 connects the forefoot groove 12 and the rearfoot groove 14. The bottoms of the forefoot groove 12 and the connecting groove 13 are on the same plane, and their depths are greater than the depth of the rearfoot groove 14.

[0027] The bottom of the heel recess 14 is also provided with a recessed air chamber 21. The bottom of the air chamber 21 is provided with a vent hole 11 through the midsole, so that the air chamber 21 is connected to the top surface of the midsole 3. The bottom of the forefoot recess 12 is provided with multiple forefoot vent holes 5 through the midsole, which are spaced apart. A forefoot shock absorber 17 is embedded in the forefoot recess 12, and a rearfoot shock absorber 18 is embedded in the heel recess 14. Since the bottom plane of the rearfoot recess 14 is higher than the bottom plane of the connecting groove 13, a continuous confluence cavity exists below the rearfoot shock absorber 18, where the outlet of the air chamber 21 and the port of the connecting groove 13 coexist, forming a direct connection port 31 that directly connects the air chamber 21 and the connecting groove (13), without being obstructed by the rearfoot shock absorber 18. The forefoot shock absorber 17 and the rearfoot shock absorber 18 are made of perforated foam material. The forefoot sole groove 12, the heel sole groove 14, and the connecting groove 13 make the midsole 3 more flexible in bending, increasing the comfort of wearing the shoe.

[0028] The midsole 3 has a heel protrusion 7 at the corresponding air chamber 21. A ring-shaped flow-guiding groove 8 is provided at the rear end of the heel protrusion 7, forming a foot-stepping island 9 in the middle of the ring groove 8. Ventilation holes 11 are located on the foot-stepping island 9, and a fan-shaped flow-guiding protrusion 10 is provided around the top of the foot-stepping island 9 around the ventilation hole 11. The flow-guiding protrusion 10 guides the airflow discharged from the ventilation hole 11 to the heel cavity. During inhalation, it guides the air in the shoe cavity to the ventilation hole 11, improving the air intake or exhaust efficiency of the ventilation hole 11. It should be noted that the shoe cavity is the cavity formed by the sole and upper after the upper is installed, accommodating the foot. The flow-guiding groove 8 has a certain cushioning effect and can temporarily store the airflow overflowing from the ventilation hole 11, preventing instantaneous airflow congestion. Multiple heel countersunk holes 6 are spaced apart on the surface of the midsole 3 at the heel position, serving as auxiliary shock absorption.

[0029] In this embodiment, the bottom of the insole 3 has recesses 15 on both sides of the connecting groove 13, and the outsole 1 has fitting protrusions 19 corresponding to the recesses 15. The fitting protrusions 19 fit into the recesses 15, providing positioning for the outsole 1 and the insole 3, increasing the contact area between the two, and improving the overall integrity and stability of the structure.

[0030] The bottom of the outer side of the insole 3 is provided with a circumferential inner groove 16, and a plurality of slots 4 are provided at intervals on the top of the circumferential inner groove 16. The edge of the outsole 1 is provided with a circumferential edging 20 that is adapted to the structure of the circumferential inner groove 16, and a plurality of locking blocks 2 that are adapted to and engage with the slots 4 are provided at intervals on the top of the circumferential edging 20.

[0031] In this embodiment, the bottom of the outsole 1 has multiple forefoot protrusions 25 spaced along its length at the forefoot position, and multiple forefoot edge protrusions 26 on both sides of each forefoot protrusion 25. The bottom of the outsole 1 also has multiple heel protrusions 27 spaced along its length at the heel position, and multiple heel edge protrusions 28 on both sides of each heel protrusion 27. The toe of the outsole 1 has a toe protrusion 29. The heel of the outsole 1 has a heel protrusion 30. The surface of the outsole 1 has edge groove combinations 23 corresponding to the forefoot edge protrusions 26, forefoot groove combinations 22 corresponding to the forefoot protrusions 25, and heel groove combinations 24 corresponding to the heel protrusions 27. The surfaces of the forefoot protrusion 25, forefoot edge protrusion 26, heel protrusion 27, heel edge protrusion 28, toe protrusion 29, and heel protrusion 30 are also provided with anti-slip textures. Each protrusion provides multi-directional grip and wear resistance. The forefoot groove combination 22, heel groove combination 24, and edge groove combination 23 make the outsole 1 more flexible to cooperate with the deformation of the midsole 3, and also reduce the weight of the outsole 1.

[0032] During installation, the midsole 3 and outsole 1 are connected by adhesive, avoiding the corresponding positions of the forefoot sole groove 12, connecting groove 13, and heel sole groove 14. The circumferential edging 20 is glued to the circumferential inner groove 16, and the locking block 2 is glued in the locking groove 4 to ensure that external dust or moisture does not easily embed into the inside of the sole from the side.

[0033] In practice, when the heel is pressed down, the air chamber 21 is compressed, and some of the internal air is pushed into the heel sole groove 14 and permeates through the pores of the heel shock absorber 18 foam, flowing into the connecting groove 13. Some air flows into the connecting groove 13 through the direct connection port 31 between the air chamber 21 and the connecting groove 13. The airflow flows along the connecting groove 13 to the forefoot, permeates through the pores of the forefoot shock absorber 17 foam, and finally exits through the forefoot vent 5, driving the hot and humid air inside the shoe out. Only a small amount of residual gas that cannot be discharged in time may overflow through the vent. When the heel lifts, the air chamber 21 and the rearfoot shock absorber 18 rebound, generating negative pressure. Cool, dry air is drawn in through the forefoot vent 5. The airflow reverses direction, passing through the pores of the forefoot shock absorber 17, the connecting groove 13, and the pores of the rearfoot shock absorber 18, ultimately filling the air chamber 21. Simultaneously, the negative pressure generated by the air chamber's rebound draws some dry air upwards into the shoe cavity through the vent 11, merging with the airflow within the air chamber to complete the air chamber backfilling. The coordinated operation of the air chamber 21, rearfoot shock absorber 18, forefoot shock absorber 17, rearfoot sole groove 14, forefoot sole groove 12, connecting groove 13, and air chamber 21 actively circulates and renews the air within the shoe cavity. The forefoot and rearfoot shock absorbers 17 and 18 absorb impact energy through their own compression deformation, while the pores of the forefoot and rearfoot shock absorbers 17 and 18 serve as channels for airflow. The air chamber 21 provides the primary power for airflow. When the heel of the shoe steps on the footrest island 9, the air chamber acts as a fulcrum to compress the foam downwards, causing the pores inside the foam to shrink significantly. This achieves shock absorption on one hand, and effectively squeezes out the air from the pores of the shock absorber, enhancing airflow. The fan-shaped airflow guide protrusions 10 further guide the airflow, improving ventilation efficiency.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
