AI Technical Summary
现有技术中的攀帮工艺是将鞋面绷紧在鞋楦上并与硬质中底固定，此工艺会导致硬质中底与硬质大底的粘合不够紧密
[0014]在传统攀帮鞋类制造中，鞋面通常被拉伸并包覆至硬质中底的下表面，然后通过胶粘的方式固定。但是，由于鞋面材料本身具有一定厚度，当鞋面被固定在中底下方时，会在硬质中底与硬质大底之间形成额外的堆叠层，使得硬质中底无法完全贴合硬质大底，从而导致粘合面出现局部空隙，影响结合强度。而在穿着过程中，由于鞋面会受到动态弯曲力，这会导致硬质中底与硬质大底粘合界面受到剪切应力，长期使用后可能出现开胶、脱层等问题。

Abstract
Description
Technical Field
[0001] This application relates to the field of footwear, specifically to a type of athletic shoe. Background Technology
[0002] Currently available bobsleigh boots generally employ a lasting process. To meet the requirements for midfoot torsional rigidity and forefoot push-off lift, a lasting structure is typically used in the midsole. This process is a crucial step in shoemaking, referring to the stretching and fixing of the upper material to the last, forming a three-dimensional shape consistent with the last. Because bobsleighs experience at least five times the force of gravity when cornering, the feet bear enormous lateral torsional forces, necessitating a rigid midsole. This midsole prevents arch collapse, avoids ankle ligament damage, and resists shoe deformation caused by centrifugal forces on the track. Current lasting technology stretches the upper to the last and fixes it to the rigid midsole, which results in insufficient adhesion between the rigid midsole and the rigid outsole. Utility Model Content
[0003] The purpose of this application is to provide a sports shoe that helps to prevent the shoe from coming apart or delaminating.
[0004] To achieve the above objectives, the following technical solution is adopted:
[0005] The first technical solution relates to a sports shoe, including an upper, a soft midsole, a hard midsole, a first panel, a second panel, and a hard outsole; the edges of the upper and the soft midsole are sewn together to form a receiving cavity, the hard midsole is placed in the receiving cavity and fits the soft midsole, the soft midsole has a first through hole and a second through hole corresponding to the forefoot and heel positions, the first panel and the second panel are respectively placed in the first through hole and the second through hole and connected to the hard midsole, the lower surfaces of the first panel and the second panel are flush with the lower surface of the soft midsole, and the hard outsole is connected to the lower surfaces of the soft midsole, the first panel, and the second panel.
[0006] The second technical solution is based on the first technical solution, wherein the thickness of the first and second cut pieces is consistent with the thickness of the soft midsole.
[0007] The third technical solution is based on the second technical solution, wherein the size of the first cut piece is smaller than the first through hole, and the size of the second cut piece is smaller than the second through hole.
[0008] The fourth technical solution is based on the second technical solution, wherein the size of the first cut piece is equal to the first through hole, and the size of the second cut piece is equal to the second through hole.
[0009] The fifth technical solution is based on the third or fourth technical solution, wherein the first cut piece is completely placed in the first through hole, and the second cut piece is completely placed in the second through hole.
[0010] The sixth technical solution is based on the second technical solution, wherein both sides of the soft midsole are coated with adhesive, the hard midsole is bonded to the soft midsole by adhesive, and the hard outsole is bonded to the soft midsole by adhesive.
[0011] The seventh technical solution is based on the fifth technical solution, wherein the upper and lower surfaces of the first and second cut pieces are both coated with adhesive, the first cut piece is bonded to the rigid midsole and rigid outsole in the first through hole, and the second cut piece is bonded to the rigid midsole and rigid outsole in the second through hole.
[0012] The eighth technical solution is based on the seventh technical solution, wherein the material of the soft midsole is fabric, and the first and second cut pieces are leather materials.
[0013] Compared with existing technologies, the above solution has the following beneficial effects:
[0014] In traditional climbing shoe manufacturing, the upper is typically stretched and wrapped around the underside of a rigid midsole, then fixed with adhesive. However, due to the inherent thickness of the upper material, when fixed under the midsole, an additional layer forms between the rigid midsole and outsole. This prevents the rigid midsole from fully adhering to the outsole, resulting in gaps at the adhesive surface and affecting bond strength. Furthermore, during wear, the upper is subjected to dynamic bending forces, causing shear stress at the adhesive interface between the rigid midsole and outsole. Over time, this can lead to problems such as glue separation and delamination.
[0015] In the first technical solution, the edges of the upper and the soft midsole are stitched together to form a cavity, and the hard midsole is placed in the cavity and adhered to the soft midsole. This helps to avoid the problem of loose bonding caused by gaps when the hard outsole is bonded due to excess upper piling on the underside of the hard midsole.
[0016] In the first technical solution, the soft midsole has a first through hole and a second through hole corresponding to the forefoot and heel positions. The first cut piece and the second cut piece are respectively placed in the first through hole and the second through hole and connected to the hard midsole. Since the surface energy of the soft midsole is low, when the soft midsole is directly bonded to the hard outsole with adhesive, the adhesion between the hard outsole and the soft midsole is not strong enough. The surface energy of the first cut piece and the second cut piece is higher than that of the soft midsole. Using the first cut piece and the second cut piece as a medium to bond the hard midsole and the hard outsole is beneficial to preventing the hard midsole and the hard outsole from falling off the soft midsole, and is more conducive to improving the stability of the sports shoe.
[0017] In the first technical solution, the lower surfaces of the first and second cut pieces are flush with the lower surface of the soft midsole. The purpose of this is to eliminate the height difference between the first and second cut pieces and the soft midsole. This helps to avoid the low bonding strength between the hard outsole and the soft midsole, as well as the first and second cut pieces, due to the height difference, and is more conducive to preventing the sports shoes from coming apart.
[0018] In the second technical solution, since the bottom surface of the hard midsole is flat, in order to eliminate the height difference between the first and second cut pieces and the soft midsole, the thickness of the first cut piece and the second cut piece should be the same as the thickness of the soft midsole.
[0019] In the third technical solution, the size of the first cut piece is smaller than the first through hole, and the size of the second cut piece is smaller than the second through hole, which facilitates placing the first cut piece into the first through hole and the second cut piece into the second through hole.
[0020] In the fourth technical solution, the size of the first cut piece is equal to the size of the first through hole, and the size of the second cut piece is equal to the size of the second through hole. When the sizes are similar, there is no gap between the first through hole and the first cut piece, and between the second through hole and the second cut piece. This helps to avoid gaps on the adhesive surface, thereby improving the adhesive strength and further helping to prevent the sports shoes from coming apart.
[0021] In the fifth technical solution, the first cut piece is completely placed in the first through hole, and the second cut piece is completely placed in the second through hole. Compared with the first cut piece not being completely placed in the first through hole and the second cut piece not being completely placed in the second through hole, the lower surfaces of the first cut piece and the second cut piece are flush with the lower surface of the soft midsole. This helps to avoid the height difference between the first cut piece, the second cut piece and the soft midsole, and is more conducive to preventing the sports shoes from coming apart.
[0022] In the sixth technical solution, the hard midsole and hard outsole are bonded to the soft midsole with an adhesive. The adhesive is easy to apply, convenient to operate, and strong, which is conducive to bonding.
[0023] In the eighth technical solution, the soft midsole is made of fabric, and the cut pieces are made of leather. The surface energy of the leather is higher than that of the fabric, which allows it to bond better with the adhesive. Furthermore, as a medium, it makes it less likely for the hard midsole and hard outsole to detach from the soft midsole. Attached Figure Description

[0036] Example
[0037] Figure 1 The sports shoe 1 in this embodiment is shown, such as Figure 1As shown, the athletic shoe 1 includes an upper 2, a soft midsole 3, a hard midsole 4, a first panel 5, a second panel 6, and a hard outsole 7. The edges of the upper 2 and the soft midsole 3 are stitched together to form a receiving cavity 8. The hard midsole 4 is placed in the receiving cavity 8 and bonded to the soft midsole 3. The soft midsole 3 has a first through-hole 9 and a second through-hole 10. The first through-hole 9 is located in the forefoot, and the second through-hole 10 is located in the heel. In this embodiment, the first panel 5 is placed inside the first through-hole 9, and its upper surface is bonded to the hard midsole 4. The second panel 6 is placed inside the second through-hole 10, and its upper surface is bonded to the hard midsole 4. In other embodiments, the first panel 5 may also be placed inside the second through-hole 10, with its upper surface connected to the hard midsole 4, and the second panel 6 may be placed inside the first through-hole 9, with its upper surface connected to the hard midsole 4. Figure 1 As shown, the lower surfaces of the first piece 5 and the second piece 6 are flush with the lower surface of the soft midsole 3, and the rigid outsole 7 is bonded to the lower surfaces of the soft midsole 3, the first piece 5, and the second piece 6. In this embodiment, the thickness of the first piece 5 and the second piece 6 is the same as the thickness of the soft midsole 3. In other embodiments, the thickness of the first piece 5 and the second piece 6 may be greater than that of the soft midsole 3, but the rigid midsole 4 needs to be grooved to make the lower surfaces of the first piece 5 and the second piece 6 flush with the lower surface of the soft midsole 3. In this embodiment, the size of the first piece 5 is equal to the size of the first through hole 9, and the size of the second piece 6 is equal to the size of the second through hole 10. In other embodiments, the size of the first piece 5 may be smaller than that of the first through hole 9, and the size of the second piece 6 may be smaller than that of the second through hole 10. In this embodiment, the first piece 5 is completely placed in the first through hole 9, and the second piece 6 is completely placed in the second through hole 10. The first piece 5 and / or the second piece 6 should not be stacked on the soft midsole 3.
[0038] Both sides of the soft midsole 3 are coated with adhesive. The hard midsole 4 and the hard outsole 7 are bonded to the soft midsole 3 with adhesive. The upper and lower surfaces of the first piece 5 and the second piece 6 are coated with adhesive. The first piece 5 is bonded to the hard midsole 4 and the hard outsole 7 through the first through-hole 9, and the second piece 6 is bonded to the hard midsole 4 and the hard outsole 7 through the second through-hole 10. The soft midsole 3 is made of fabric, while the first piece 5 and the second piece 6 are made of leather.
[0039] Figure 2 The soft midsole 3 in this embodiment is shown. When manufacturing the athletic shoe 1 in this embodiment, the soft midsole 3 needs to undergo pre-processing. First, holes are made in the soft midsole 3 at the stress points of the forefoot and heel to form a first through hole 9 and a second through hole 10. For example... Figure 2 As shown, the cut material is sewn together with the soft midsole 3 using water-soluble thread 11 at the first through hole 9 and the second through hole 10. The hard midsole 4 is then fixed to the shoe last using an air gun, as shown. Figure 3As shown, the pre-treated soft midsole 3 is sewn together with the upper 2. Then, the sewn upper 2 and soft midsole 3 are stretched and fitted into the shoe last, so that the hard midsole 4 fits snugly against the soft midsole 3. Next, the water-soluble thread 11 is dissolved with water, and the cut soft midsole 3 is removed, leaving the soft midsole 3 with a first through-hole 9 and a second through-hole 10 at the forefoot and heel. The first cut piece 5 and the second cut piece 6 are the same size as the first through-hole 9 and the second through-hole 10, and are glued to the hard midsole 4 according to their positions. Finally, the hard outsole 7 is attached to the soft midsole 3 and the lower surfaces of the first cut piece 5 and the second cut piece 6.
[0040] In this embodiment, in order to avoid uneven stress on the soft midsole 3 after the first through hole 9 and the second through hole 10 have been opened after the shoe last is inserted, the first through hole 9 and the second through hole 10 are sealed with water-soluble thread 11 before the shoe last is inserted, and then dissolved with water after the shoe last is inserted. This helps to prevent the soft midsole 3 from wrinkling after the shoe last is inserted, which would cause the lower surface to stack and the stress to be uneven, and helps to prevent the sports shoe 1 from coming apart.
[0041] In this embodiment, the edges of the upper 2 and the soft midsole 3 are stitched together to form a receiving cavity 8. The hard midsole 4 is placed in the receiving cavity 8 and adheres to the soft midsole 3. This helps to avoid the problem of loose adhesion caused by gaps when the hard outsole 7 is glued due to excess upper 2 stacking on the lower surface of the hard midsole 4.
[0042] In this embodiment, the soft midsole 3 is provided with a first through hole 9 and a second through hole 10 at the positions corresponding to the forefoot and heel. The first cut piece 5 and the second cut piece 6 are respectively placed in the first through hole 9 and the second through hole 10 and connected to the hard midsole 4. Since the surface energy of the soft midsole 3 is low, when the soft midsole 3 is directly bonded to the hard outsole 7 with adhesive, the adhesion between the hard outsole 7 and the soft midsole 3 is not strong enough. The surface energy of the first cut piece 5 and the second cut piece 6 is higher than that of the soft midsole 3. Using the first cut piece 5 and the second cut piece 6 as a medium to bond the hard midsole 4 and the hard outsole 7 is beneficial to prevent the hard midsole 4 and the hard outsole 7 from falling off the soft midsole 3, and is more conducive to improving the stability of the sports shoe 1.
[0043] In this embodiment, the lower surfaces of the first piece 5 and the second piece 6 are flush with the lower surface of the soft midsole 3. The purpose is to eliminate the height difference between the first piece 5 and the second piece 6 and the soft midsole 3. This helps to avoid the low bonding strength between the hard outsole 7 and the soft midsole 3, the first piece 5 and the second piece 6 due to the height difference, and is more conducive to preventing the sports shoe 1 from coming apart.
[0044] In this embodiment, since the bottom surface of the rigid insole 4 is flat, in order to eliminate the height difference between the first piece 5 and the second piece 6 and the soft insole 3, the thickness of the first piece 5 and the second piece 6 should be the same as the thickness of the soft insole 3.
[0045] In this embodiment, the size of the first cut piece 5 is smaller than the first through hole 9, and the size of the second cut piece 6 is smaller than the second through hole 10, which facilitates placing the first cut piece 5 into the first through hole 9 and the second cut piece 6 into the second through hole 10.
[0046] In this embodiment, the size of the first cut piece 5 is equal to the size of the first through hole 9, and the size of the second cut piece 6 is equal to the size of the second through hole 10. When the sizes are similar, there is no gap between the first through hole 9 and the first cut piece 5, and between the second through hole 10 and the second cut piece 6. This helps to avoid gaps on the adhesive surface to improve the adhesive strength and is more conducive to preventing the sports shoe 1 from coming apart.
[0047] In this embodiment, the first cut piece 5 is completely placed in the first through hole 9, and the second cut piece 6 is completely placed in the second through hole 10. Compared with the first cut piece 5 not being completely placed in the first through hole 9 and the second cut piece 6 not being completely placed in the second through hole 10, the lower surfaces of the first cut piece 5 and the second cut piece 6 are flush with the lower surface of the soft midsole 3. This helps to avoid the height difference between the first cut piece 5, the second cut piece 6 and the soft midsole 3, and is more conducive to preventing the sports shoe 1 from coming apart.
[0048] In this embodiment, the hard midsole 4 and the hard outsole 7 are bonded to the soft midsole 3 by an adhesive. The adhesive is easy to apply, convenient to operate, and strong, which is beneficial for bonding.
[0049] In this embodiment, the soft midsole 3 is made of fabric, and the cut piece is made of leather material. The surface energy of the leather material is higher than that of the fabric, which allows it to bond better with the adhesive. Furthermore, as a medium, it makes the hard midsole 4 and the hard outsole 7 less likely to detach from the soft midsole 3.
[0050] 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.
