Description

Technical Field

[0001] The utility model specifically relates to a highly elastic and comfortable composite insole and a sole. Background Art

[0002] In today's market, casual shoes and the like usually adopt an integrated design, tightly combining the upper, insole and sole through an adhesive process. The insoles in this design often use a single-thickness thin fabric or adhesive material, with only a thin buffer layer covering the sole. However, this design ignores the needs of the feet for softness and comfort. Due to the thinness limitation of the insole, when the wearer walks or stands, the feet directly contact the hard sole, lacking sufficient buffering, resulting in a rigid and uncomfortable wearing experience. This hard contact not only reduces the comfort during walking but may also cause foot fatigue or discomfort after long-term use, highlighting the obvious deficiency of the existing insole design in improving wearing comfort. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a highly elastic and comfortable composite insole and a sole in view of the above-mentioned deficiencies of the prior art, which show remarkable technical effects in improving comfort, durability and environmental performance.

[0004] To achieve the above object, the utility model provides the following technical solution: a highly elastic and comfortable composite insole, characterized in that: it includes an insole body made of a highly elastic material, the outer circle of the insole body is covered with an outer edge binding, and wood chips or rice bran are doped in the outer edge binding.

[0005] By adopting the above technical solution, the material of the insole body can be selected from SBS super-elastic body, TPR ordinary material or leather, realizing remarkable improvement in the wearing comfort and durability of the insole. The insole body is made of a highly elastic material such as SBS super-elastic body, TPR ordinary material or leather. Due to their excellent elasticity and softness, these materials can provide good buffering effects, reduce the impact on the feet during walking or exercise, and thus significantly improve the wearing comfort. The design of the outer edge binding not only enhances the hardness of the insole, facilitates the processing and production of the insole, is not easily deformed, and extends the service life, but also further increases the softness and breathability of the insole by doping wood chips or rice bran. The porous structure of wood chips and rice bran helps to absorb foot sweat and keep the shoes dry. At the same time, their natural materials endow the insole with an environmental and healthy characteristic. In addition, the addition of the outer edge binding also helps the insole to maintain a stable position in the shoe, reduce sliding, ensure the fit between the insole and the feet, and further improve the wearing experience. Overall, this insole design shows remarkable technical effects in improving comfort, durability and environmental performance.

[0006] The above-mentioned highly elastic and comfortable composite insole can be further configured as follows: An embedding groove is provided below the insole body and at the front end of the insole body. The embedding groove is recessed towards the upper side of the insole body, and a backing plate is fitted in the embedding groove.

[0007] With the above technical solution, by setting an embedding groove below the highly elastic and comfortable composite insole body and at the front end, and fitting a backing plate in the groove, the functionality and comfort of the insole are further enhanced. The design of the embedding groove enables the insole to provide additional support and cushioning in key areas such as the forefoot while maintaining a lightweight overall structure. The addition of the backing plate allows for the selection of materials with different hardnesses according to needs to meet the requirements of different users, providing better arch support or relieving foot pressure. The recessed design of the embedding groove ensures a tight fit between the backing plate and the insole body, preventing the backing plate from sliding or shifting inside the shoe.

[0008] The above-mentioned highly elastic and comfortable composite insole can be further configured as follows: Clamping grooves are provided on both sides below the insole body and along the outline of the insole body. The clamping grooves are strip-shaped and extend along the contour of the insole body, and the clamping grooves are recessed towards the upper side of the insole body.

[0009] With the above technical solution, the clamping grooves are designed to facilitate the smooth clamping of the insole when the shoe upper is being clamped after the insole is processed. Moreover, wood chips or rice bran are doped in the outer edge binding of the insole body, enhancing the strength and hardness of the outer edge binding. In this way, they cooperate with each other to better clamp the shoe upper and facilitate production.

[0010] The above-mentioned highly elastic and comfortable composite insole can be further configured as follows: The depth of the embedding groove is greater than the depth of the clamping groove.

[0011] With the above technical solution, the left-right swinging of the cushion block is avoided. At the same time, the function of the embedding groove is to install the backing plate, while the clamping groove is for facilitating clamping. Therefore, the clamping groove should not be designed too deep to avoid reducing the performance of the insole.

[0012] The above-mentioned highly elastic and comfortable composite insole can be further configured as follows: A number of groups of cylindrical holes are evenly distributed in the middle part below the insole body.

[0013] With the above technical solution, the air permeability is improved, the weight of the insole is reduced, and the cost is lowered.

[0014] The above-mentioned highly elastic and comfortable composite insole can be further configured as follows: A wear-resistant layer is attached to the upper side of the insole body.

[0015] With the above technical solution, the wear-resistant layer can be made of artificial leather, animal skin, fiber cloth, etc., and then adhered to the insole body to form an insole. The wear-resistant layer is used to replace the polyurethane insole in contact with the sole of the foot to avoid abrasion.

[0016] The sole, including the outsole, is characterized in that: it further includes the insole as described in any one of the foregoing technical solutions. A shoe groove is provided above the outsole, and the lower part of the insole is snapped into the shoe groove. The outsole and the insole are connected by cold gluing.

[0017] Adopting the above technical solution, by setting a shoe groove above the outsole and snapping the lower part of the insole into the shoe groove, and through cold gluing, a tight combination of the insole and the sole is achieved. The sole composed of the insole described in any one of the foregoing has good comfort. It not only meets the required hardness of the sole but also has good elasticity after wearing. Compared with the existing soles, it has better comfort and longer service life.

[0018] The above sole can be further configured as: a plurality of groups of grooves are evenly distributed in the shoe groove, and anti-slip patterns are provided below the outsole.

[0019] Adopting the above technical solution, grooves are designed to increase the friction between the insole and the outsole, ensure the insole is stable in the shoe groove, reduce sliding, provide better wearing stability, while reducing the weight of the sole and also reducing costs. Anti-slip patterns are designed to enhance the grip of the sole.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Example 1: As Figure 1 shown, the highly elastic and comfortable composite insole a includes an insole body a1 made of a highly elastic material. The outer ring of the insole body a1 is covered with an outer edge binding a2, and sawdust or rice bran is doped in the outer edge binding a2. The material of the insole body a1 can be selected from SBS superelastic body, TPR ordinary material or leather, achieving significant improvements in enhancing the wearing comfort and durability of the insole a. The insole body a1 is made of a highly elastic material such as SBS superelastic body, TPR ordinary material or leather. Due to their excellent elasticity and softness, these materials can provide good buffering effects, reduce the impact on the feet during walking or exercise, and thus significantly improve the wearing comfort. The design of the outer edge binding a2 not only enhances the hardness of the insole a, facilitates the processing and production of the insole a, is not easily deformed, and extends the service life, but also further increases the softness and breathability of the insole a by doping sawdust or rice bran. The porous structure of sawdust and rice bran helps absorb foot sweat, keep the shoes dry, and at the same time their natural materials endow the insole a with an environmentally friendly and healthy characteristic. In addition, the addition of the outer edge binding a2 also helps the insole a maintain a stable position in the shoe, reduce slippage, ensure the fit between the insole a and the feet, and further enhance the wearing experience. Overall, this insole a design shows significant technical effects in enhancing comfort, durability, and environmental performance.

[0028] Below the insole body a1 and at the front end of the insole body a1, there is an embedding groove a3. The embedding groove a3 is recessed towards the upper side of the insole body a1, and a backing plate a4 is fitted in the embedding groove a3. Through the technical solution of setting an embedding groove a3 below the highly elastic and comfortable composite insole body a1 and at the front end and fitting a backing plate a4 in the groove, the functionality and comfort of the insole a are further enhanced. The design of the embedding groove a3 enables the insole a to provide additional support and buffering in key areas such as the forefoot while maintaining the overall structure light. The addition of the backing plate a4 can select materials with different hardnesses according to needs to adapt to the needs of different users, provide better arch support or relieve foot pressure. The recessed design of the embedding groove a3 ensures the tight combination between the backing plate a4 and the insole body a1, preventing the backing plate a4 from sliding or shifting in the shoe.

[0029] On both sides of the insole body and below the insole body a1, there are clamping grooves a5. The clamping grooves a5 are strip-shaped and extend along the contour of the insole body a1. The clamping grooves a5 are recessed towards the upper side of the insole body a1. The purpose of designing the clamping grooves a5 is to facilitate the smooth clamping of the insole a when the shoe upper is clamped after the insole a is processed. Moreover, sawdust or rice bran is doped in the outer edge binding a2 of the insole body a1, which improves the strength and hardness of the outer edge binding a2. With such mutual cooperation, it can better clamp the shoe upper and facilitate production.

[0030] The depth of the embedding groove a3 is greater than that of the clamping groove a5. To prevent the spacer from swinging left and right. At the same time, the function of the embedding groove a3 is to install the backing plate a4, while the clamping groove a5 is for facilitating clamping. Therefore, the clamping groove a5 should not be designed too deep to avoid reducing the performance of the insole a.

[0031] A number of groups of cylindrical holes a6 are evenly distributed in the middle part below the insole body a1. To improve breathability, reduce the weight of the insole a, and lower costs.

[0032] A wear-resistant layer a7 is attached above the insole body a1. The wear-resistant layer a7 can be selected from artificial leather, animal skin, fiber cloth, etc., and then adhered to the insole body a1 to form the insole a. The wear-resistant layer a7 is used to contact the sole instead of the polyurethane insole a to avoid abrasion.

[0033] Example Two: As Figures 2 to 4 shown in the sole, which includes the outsole b, and also includes the insole a according to any one of the foregoing technical solutions. A shoe groove b1 is provided above the outsole b, and the lower part of the insole a is snapped into the shoe groove b1. The outsole b and the insole a are connected by cold bonding. By providing the shoe groove b1 above the outsole b and snapping the lower part of the insole a into the shoe groove b1, and through cold bonding, a tight combination of the insole a and the sole is achieved. The sole composed of the insole a according to any one of the foregoing has good comfort, which not only meets the required hardness of the sole but also has good elasticity after wearing. Compared with the existing soles, it has better comfort and longer service life.

[0034] A number of groups of grooves b2 are evenly distributed in the shoe groove b1, and anti-slip patterns b3 are provided below the outsole b. Designing the grooves b2 increases the friction between the insole a and the outsole b, ensures the insole a is stable in the shoe groove b1, reduces sliding, provides better wearing stability, while reducing the weight of the sole and also lowering costs. Designing the anti-slip patterns b3 enhances the sole's grip.
