Description

Technical Field

[0001] This application relates to the field of footwear and apparel, specifically to a shoe sole and a shoe. Background Technology

[0002] Taekwondo is typically practiced indoors, but to effectively protect the feet from abrasions, impacts, and ground friction, athletes must wear specialized taekwondo shoes during training and competition. To meet the demands of taekwondo movements for flexible foot control, most taekwondo shoes feature a two-piece outsole design, consisting of independent forefoot and heel sections. This allows the forefoot and heel to bend and deform independently during movement, reducing obstruction to kicks and footwork. However, wearing these shoes increases the risk of injury when practicing taekwondo. Summary of the Invention

[0003] Through continuous observation, analysis, and experimentation, the applicant discovered that the reason why Taekwondo shoes in existing technology are prone to injury during Taekwondo practice is as follows: Existing Taekwondo shoes divide the outsole into a forefoot and heel section, resulting in a lack of stable connection between the midsole and upper in the arch area. After repeated stress, the shoe body is prone to irreversible loosening and deformation, making the shoe unable to fit snugly against the foot, significantly reducing its support and fit, and feeling loose when worn. Because the shoe body does not fit snugly enough, during high-dynamic movements such as pushing off the ground, rapid weight transfer, and rotational braking, the foot will experience uncontrollable relative slippage within the shoe. This not only severely weakens the foot's perception of ground reaction force and the efficiency of power transmission, making it difficult to execute Taekwondo movements in time, but also causes the loose shoe body to fail to provide sufficient lateral support to the ankle joint during lateral push-offs, spin kicks, and sudden stops and changes of direction, making the foot prone to lateral swaying and thus leading to foot injuries.

[0004] Therefore, the purpose of this application is to improve the deficiencies in the prior art to a certain extent, and to provide a sole and shoe that not only facilitates the wearer's flexible control of the foot, but also conforms well to the wearer's foot during exercise.

[0005] Based on the above, and in order to improve the deficiencies of the prior art and achieve the purpose of this application, the applicant adopts the following technical solution to solve the problem: Option 1 relates to a shoe sole, which includes a midsole, an outsole, and a support member. The outsole includes a forefoot member located in the forefoot area and a heel member located in the heel area. The support member is also fixed to the midsole and has a surrounding portion and a supporting portion. The rigidity of the supporting portion is higher than that of the midsole. The supporting portion is located in the arch area of ​​the shoe sole and extends from the inside of the midsole to the outside of the midsole. The supporting portion is also located between the outsole and the midsole in a vertical direction. The two ends of the surrounding portion are connected to the supporting portion, and the surrounding portion also surrounds the heel area of ​​the midsole around the side of the midsole.

[0006] In this technical solution, the outsole includes a forefoot component located in the forefoot area and a heel component located in the heel area. That is, by using separate forefoot and heel components, the forefoot and heel areas of the sole can still bend separately when the athlete kicks, steps, and rotates the forefoot, thereby maintaining the foot control flexibility of the taekwondo shoe. The support component is also fixed to the midsole and has a surrounding section and a supporting section. The supporting section is located in the arch area of ​​the sole and extends from the inside to the outside of the midsole. The supporting section is also located vertically between the outsole and the midsole. The two ends of the surrounding section are connected to the supporting section, and the surrounding section also surrounds the heel area of ​​the midsole around the side of the midsole. This creates a continuous force structure between the heel area and the arch area of ​​the sole. When the athlete performs a spin kick with single-leg support, the forefoot and heel are subjected to ground reaction forces in different directions, causing the sole to twist. The supporting section can use its high rigidity to limit excessive twisting in the arch area of ​​the midsole. At the same time, the tensile force generated by the heel area tilting to one side or expanding outward can be transmitted to the supporting section through the surrounding section and restrained by the supporting section. The reaction force generated by the supporting section can also be transmitted to the surrounding section through the connection, limiting the loose deformation of the heel area of ​​the midsole relative to the arch area. Therefore, the sole using this technical solution not only facilitates flexible foot control for the wearer, but also reduces the loosening and deformation that occurs after repeated pushing, rotating, and landing, thus better conforming to the wearer's foot. Furthermore, it provides some support for the arch and improves the sole's resistance to relative torsion between the forefoot and heel.

[0007] Option 2 is based on Option 1, wherein the surrounding part includes a first connecting part, a second connecting part, and a bending part. The first connecting part is located on the inner side of the midsole side corresponding to the arch area, and the second connecting part is located on the outer side of the midsole side corresponding to the arch area. The bending part surrounds the heel area of ​​the midsole around the side of the midsole, and its two ends are respectively connected to the first connecting part and the second connecting part. The lengths of the two sides of the support part along the width direction of the sole correspond to the first connecting part and the second connecting part, and are respectively connected to the first connecting part and the second connecting part.

[0008] In this technical solution, the first connecting part and the second connecting part are located on the inner and outer sides of the arch area on the side of the midsole, respectively. The lengths of the two sides of the support part in the width direction correspond to and are connected to the first and second connecting parts, respectively. This allows the inner and outer sides of the support part to form continuous connection areas of matching length with the first and second connecting parts. When the athlete rotates around the forefoot of the supporting foot, causing the inner and outer sides of the sole to be stretched and compressed, the heel sway load on the bending part can be transmitted to the inner and outer sides of the support part through the first and second connecting parts, along the matching connection areas, rather than being concentrated at a local connection point. The torsional reaction force generated by the support part can also be transmitted back to the surrounding part along the corresponding connection area. This reduces local stress concentration at the connection point, makes the force transmission between the inner and outer sides of the sole more continuous, reduces the possibility of unilateral pulling of the surrounding part, skewness of the support part, and local separation at the connection point, and makes the overall structure more stable.

[0009] Option 3 is based on Option 2, wherein the curved portion extends upward to be suitable for wrapping at least part of the Achilles tendon area.

[0010] In this technical solution, the curved part extends upward to be suitable for wrapping at least part of the Achilles tendon area. When the athlete performs continuous jumps, retreats and stops suddenly, or kicks and lands, causing the heel to lift upward relative to the sole of the shoe, or performs a spinning kick to brake, causing the heel to sway inward or outward, the upwardly extending curved part can bear the above-mentioned lifting force and lateral force, and transmit them to the support part through the first connecting part and the second connecting part. The support part provides a restraining reaction force, thereby reducing heel slippage and lateral swaying, and improving the shoe's heel wrapping and foot fit.

[0011] Option 4 is based on Option 1, in which the support component is integrally formed.

[0012] In this technical solution, the support component is integrally molded, which not only facilitates manufacturing but also improves the overall structural stability.

[0013] Option 5 is based on Option 1, wherein the front end of the support is at least partially covered by the forefoot component, and the rear end is at least partially covered by the heel component.

[0014] In this technical solution, the front end of the support part is at least partially covered by the forefoot component, and the rear end is at least partially covered by the heel component, so that the forefoot component and the heel component can limit the front and rear ends of the support part in the vertical direction, reducing the possibility of the support part lifting up or separating from the midsole during repeated bending of the front and rear ends of the sole.

[0015] Option 6 is based on Option 1, in which the support part is also provided with several through holes, which are located in the gap formed between the forefoot and heel parts along the front-back direction.

[0016] In this technical solution, the support part is also provided with several through holes. Along the front-to-back direction, the through holes are located in the gap formed between the forefoot and heel parts, which is conducive to ventilation.

[0017] Option 7 is based on Option 1, wherein the surrounding part is fixed to the midsole so that the support is fixed to the midsole.

[0018] In this technical solution, the surrounding part is fixed to the midsole so that the support is fixed to the midsole. Therefore, the support is fixed to the midsole in the vertical direction by connecting with the surrounding part. Compared with directly sewing or gluing the support to the midsole in the vertical direction, it can avoid the support's area covering the midsole from affecting the performance of the midsole itself, and the manufacturing is also simpler.

[0019] Option 8 is based on Option 7, in which the surrounding part is sewn to the midsole, and the forefoot and heel parts are glued to the midsole.

[0020] In this technical solution, the surrounding part is sewn to the midsole, and the forefoot and heel parts are glued to the midsole, which facilitates manufacturing.

[0021] Solution 9 relates to a shoe, which includes an upper and a sole as described in any one of solutions 1 to 8, wherein the upper is fixed to the sole. Attached Figure Description

In this embodiment, the front-back direction is the length direction of the shoe, the left-right direction is the width direction of the shoe, and the vertical direction is the height direction of the shoe.

[0034] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings.

[0035] Example 1 like Figure 1 and Figure 2 As shown, this embodiment provides a shoe, which includes an upper and a sole, with the upper fixed to the sole. This shoe is mainly used for Taekwondo. The sole includes a midsole, an outsole 1, and a support member 2.

[0036] The outsole 1 includes a forefoot component 11 located in the forefoot area and a heel component 12 located in the heel area. The forefoot component 11 and the heel component 12 are relatively independent and there is a gap between them. The forefoot component 11 and the heel component 12 can be made of materials such as rubber, which is prior art and will not be described in detail here.

[0037] like Figure 2-5As shown, support member 2 is fixed to the midsole. Support member 2 has a surrounding portion 22 and a supporting portion 21. The rigidity of the supporting portion 21 is higher than that of the midsole. The supporting portion 21 is located in the arch area of ​​the sole and extends from the inside of the midsole to the outside of the midsole. The supporting portion 21 is also located vertically between the outsole 1 and the midsole. The supporting portion 21 also has several through holes 3. The two ends of the surrounding portion 22 are connected to the supporting portion 21. The surrounding portion 22 also surrounds the heel area of ​​the midsole around the side of the midsole. Specifically, the surrounding portion 22 includes a first connecting portion 221, a second connecting portion 222, and a bending portion 223. The first connecting portion 221 is located on the inside of the midsole side corresponding to the arch area. The second connecting portion 222 is located on the outside of the midsole side corresponding to the arch area. The bending portion 223 surrounds the heel area of ​​the midsole around the side of the midsole, and its two ends are connected to the first connecting portion 221 and the second connecting portion 222, respectively. The support portion 21 has two sides of length corresponding to (e.g., the same or greater than) the first connecting portion 221 and the second connecting portion 222 along the width direction of the sole, and is correspondingly connected to the first connecting portion 221 and the second connecting portion 222. The curved portion 223 also extends upward to be suitable for wrapping at least part of the Achilles tendon area. The support member 2 can be made of materials such as CDP, or it can be integrally molded.

[0038] In terms of manufacturing, such as Figure 5 As shown, the support member 2 is integrally formed. First, the second connecting part 222 and the surrounding part 22 are sewn to the midsole or upper. Then, the support part 21 is bent so that it is located under the midsole. Next, the first connecting part 221 is sewn to the midsole or upper, so that the surrounding part 22 is fixed to the midsole by sewing, thereby fixing the support member 2 to the midsole. Then, the forefoot part 11 and the heel part 12 are fixed to the midsole with glue, so that the front end of the support part 21 is at least partially covered by the forefoot part 11, and the rear end of the support part 21 is at least partially covered by the heel part 12. The through hole 3 is located in the gap formed between the forefoot part 11 and the heel part 12 in the front-back direction.

[0039] In this embodiment, the outsole 1 includes a forefoot component 11 located in the forefoot area and a heel component 12 located in the heel area. That is, by using a forefoot component 11 and a heel component 12 that are separate from each other, the forefoot area and the heel area of ​​the sole can still bend separately when the athlete kicks, steps, and rotates the forefoot, thereby maintaining the foot control flexibility of the taekwondo shoe. The support member 2 is also fixed to the midsole, and it has a surrounding part 22 and a support part 21. The support part 21 is also located in the arch area of ​​the sole and extends from the inside of the midsole to the outside of the midsole. The support part 21 is also located between the outsole 1 and the midsole in the vertical direction. The two ends of the surrounding part 22 are connected to the support part 21. The surrounding part 22 also surrounds the heel area of ​​the midsole around the side of the midsole, thereby forming a continuous force structure between the heel area and the arch area of ​​the sole. When the athlete performs a spin kick with one foot, the forefoot and heel are subjected to ground reaction forces in different directions, and the sole tends to twist. The support part 21 can use its high rigidity to limit the excessive twisting of the arch area of ​​the midsole. At the same time, the tension generated by the heel area tilting to one side or expanding outward can be transmitted to the support part 21 through the surrounding part 22 and restrained by the support part 21. The reaction force generated by the support part 21 can also be transmitted to the surrounding part 22 through the connection, limiting the loose deformation of the heel area of ​​the midsole relative to the arch area. Therefore, the sole of this embodiment not only facilitates flexible foot control for the wearer, but also reduces the loosening and deformation of the sole after repeated pushing, rotating, and landing, thus better conforming to the wearer's foot. Furthermore, it provides some support for the arch and improves the sole's resistance to relative torsion between the forefoot and heel.

[0040] In this embodiment, the first connecting portion 221 and the second connecting portion 222 are located on the inner and outer sides of the arch region on the side of the midsole, respectively. The lengths of the two sides of the support portion 21 in the width direction correspond to and are connected to the first connecting portion 221 and the second connecting portion 222 in the front-back direction, respectively. This allows the inner and outer sides of the support portion 21 to form continuous connection areas with matching lengths with the first connecting portion 221 and the second connecting portion 222, respectively. When the athlete rotates around the forefoot of the supporting foot, causing the inner and outer sides of the sole to be stretched and compressed, the heel sway load on the bending portion 223 can be transmitted to the inner and outer sides of the support portion 21 via the first connecting portion 221 and the second connecting portion 222, along the matching connection areas, rather than being concentrated at a local connection point. The torsional reaction force generated by the support portion 21 can also be transmitted back to the surrounding portion 22 along the corresponding connection areas. This reduces local stress concentration at the connection points, makes the force transmission between the inner and outer sides of the sole more continuous, reduces the possibility of unilateral pulling of the surrounding portion 22, skewness of the support portion 21, and local separation at the connection point, and makes the overall structure more stable.

[0041] In this embodiment, the curved portion 223 extends upward to be suitable for wrapping at least part of the Achilles tendon area. When the athlete performs continuous jumps, retreats and stops suddenly, or kicks and lands, causing the heel to lift upward relative to the sole of the shoe, or performs a spinning kick and brakes, causing the heel to sway inward or outward, the upwardly extending curved portion 223 can bear the above-mentioned lifting force and lateral force, and transmit them to the support portion 21 through the first connecting portion 221 and the second connecting portion 222. The support portion 21 provides a restraining reaction force, thereby reducing heel slippage and lateral swaying, and improving the shoe's heel wrapping and foot fit.

[0042] In this embodiment, the support member 2 is integrally formed, which not only facilitates manufacturing but also improves the overall structural stability.

[0043] In this embodiment, the front end of the support part 21 is at least partially covered by the forefoot member 11, and the rear end is at least partially covered by the heel member 12, so that the forefoot member 11 and the heel member 12 can limit the front and rear ends of the support part 21 in the vertical direction, reducing the possibility of the support part 21 lifting up or separating from the midsole during repeated bending of the front and rear ends of the sole.

[0044] In this embodiment, the support part 21 is also provided with a plurality of through holes 3. Along the front-to-back direction, the through holes 3 are located in the gap formed between the forefoot part 11 and the heel part 12, which is conducive to ventilation.

[0045] In this embodiment, the surrounding part 22 is fixed to the midsole so that the support member 2 is fixed to the midsole. Therefore, the support part 21 is fixed to the midsole in the vertical direction by connecting with the surrounding part 22. Compared with directly sewing or pasting the support part 21 to the midsole in the vertical direction, the support part 21 can avoid affecting the performance of the midsole itself due to its area coverage, and the manufacturing is also simpler.

[0046] In this embodiment, the surrounding part 22 is sewn to the midsole, and the forefoot part 11 and the heel part 12 are glued to the midsole, which facilitates manufacturing.

[0047] The description of the above specification and embodiments is used to explain the scope of protection of this application, but does not constitute a limitation on the scope of protection of this application.
