Abstract
Description
Technical Field
[0001] This utility model relates to the field of shoe sole technology, and in particular to a shoe sole that adaptively adjusts the width of the foot. Background Technology
[0002] Currently, there are many types of shoe soles on the market, but most soles have a fixed width for the foot area, a design based on standard human foot sizes. In practical applications, due to significant differences in the physiological characteristics of different individuals' feet, especially the wide variation in foot width, fixed-width soles cannot meet the needs of all users.
[0003] For users with wide feet, wearing shoes with standard-width soles presents several problems. Firstly, insufficient internal space causes compression on the sides of the foot, leading to pain and discomfort over time, and in severe cases, potentially affecting blood circulation and harming the user's health. Secondly, choosing a size larger for comfort can result in the heel not fitting properly, shoes slipping off easily, significantly reducing wearing comfort and walking safety. Furthermore, once the existing soles are manufactured, their foot width is difficult to change. This not only limits user choices but also increases production and inventory costs for manufacturers, as they need to produce soles of various widths to meet specific user needs, making it difficult to accurately match market demand.
[0004] Therefore, there is an urgent need for a shoe sole that can adaptively adjust to the width of the foot to solve the problems of existing shoe soles being unable to adapt to users with different foot widths, resulting in discomfort and inconvenience in wearing and using them.
[0005] Therefore, there is an urgent need to provide an improved technical solution to solve the above-mentioned technical problems. Utility Model Content

[0011] The second connecting part connects between the insertion parts of two adjacent different first connecting parts, and the second connecting part fits into the gap between the two insertion parts.
[0012] Furthermore, the second connecting part is rhomboid in shape.
[0013] Furthermore, it also includes:
[0014] The waterproof membrane is placed in the middle of the widened structure. When the widened part is in a contracted state, the waterproof membrane is in a folded state.
[0015] Furthermore, it also includes:
[0016] The heel area is also equipped with a widening mesh.
[0017] Furthermore, the network is expanded into an integrated structure.
[0018] The beneficial effects of this utility model are:
[0019] 1. This utility model can widen the width of the foot by setting the widening mesh, making the user's feet more comfortable.
[0020] 2. This utility model uses a rhombus shape to make the structure more stable and the state easier to maintain. Attached Figure Description

[0027] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0028] Example 1:
[0029] This embodiment provides a shoe sole that adaptively adjusts the width of the foot, including:
[0030] Body 1, which includes a foot part 2 and a heel part 3;
[0031] The foot portion 2 is provided with a widening mesh 4, which consists of several arrays of widening structures, including:
[0032] The first connecting part 5 is provided with a groove 8, and an insertion part 7 is formed between two adjacent grooves 8. The insertion part 7 of the first connecting part 5 is correspondingly disposed in the groove 8 of the adjacent first connecting part 5.
[0033] The second connecting part 6 is connected between the insertion parts 7 of two adjacent different first connecting parts 5, and the second connecting part 6 is fitted into the gap between the two insertion parts 7.
[0034] The materials used for shoe soles are diverse, each with its own unique performance characteristics. Common materials include the following:
[0035] Rubber: Rubber is a traditional and widely used material for shoe soles, and it is divided into natural rubber and synthetic rubber. Natural rubber soles have good elasticity and wear resistance, and excellent anti-slip performance. They are often used in sports shoes and casual shoes, providing a comfortable feel and grip during exercise. Synthetic rubber, on the other hand, performs well in terms of wear resistance and aging resistance. Its hardness and toughness can be adjusted according to needs. For example, it is commonly found in outdoor shoes and work shoes, and can adapt to complex ground environments.
[0036] Polyurethane (PU): Polyurethane soles are lightweight, possess high strength and good abrasion resistance, and offer excellent cushioning, effectively reducing the impact on the feet and joints during walking. They also exhibit good oil and chemical resistance, making them resistant to common oil stains and chemicals. Commonly found in mid-to-high-end athletic shoes and leather shoes, they provide wearers with a lightweight and comfortable wearing experience.
[0037] Ethylene-vinyl acetate copolymer (EVA): The biggest advantage of EVA soles is their extremely light weight, while also possessing good flexibility and cushioning, making them soft, comfortable, and conforming to the foot. They are also relatively inexpensive, making them widely used in casual shoes, slippers, and children's shoes. However, their abrasion resistance is relatively weak, making them unsuitable for prolonged walking on rough surfaces.
[0038] Thermoplastic elastomers (TPEs): TPE soles combine the advantages of rubber and plastics, possessing the high elasticity and weather resistance of rubber while having the processing properties of plastics. They are recyclable and environmentally friendly. With a wide range of hardness, they can be customized to meet various needs and are commonly used in fashion and functional footwear to satisfy diverse design and usage requirements.
[0039] Polyvinyl chloride (PVC): PVC soles are relatively inexpensive, have good hardness and wear resistance, and are easy to process and mold, allowing for the creation of various complex shapes and patterns. However, PVC soles are relatively hard, less comfortable, and have poor breathability, and are often found in some inexpensive sandals and slippers.
[0040] The main body 1 includes a forefoot portion 2 and a heel portion 3. A widening mesh 4 is formed in the middle area of the forefoot portion 2. The widening mesh 4 is composed of several evenly distributed widening structures, such as... Figure 2 , 3 As shown, Figure 2 To expand the undeveloped diagram of net4, such as Figure 2 As shown, the widening structure is formed by cutting through a linear structure on the main body 1 using a cutting tool. The widening structure includes a first connecting part 5, with grooves 8 on both sides of the first connecting part 5. A protruding insertion part 7 is formed between two adjacent grooves 8. When the widening net 4 is not unfolded, the insertion part 7 of the first connecting part 5 is correspondingly placed in the groove 8 of the adjacent first connecting part 5. The two ends of the second connecting part 6 are connected between one corner of the insertion part 7 and one corner of the other insertion part 7, and the length of the second connecting part 6 is greater than the width between the two insertion parts 7. The second connecting part 6 needs to be compressed from not unfolded to unfolded, so that the second connecting part 6 undergoes a certain deformation, causing the widening net 4 to unfold. Since it is necessary to overcome the deformation to return to the unfurled state, the widening net 4 can remain in the unfolded state in its natural state. The widening net 4 can widen the width of the foot part 2, making the user's foot more comfortable.
[0041] Example 2:
[0042] This embodiment provides a shoe sole that adaptively adjusts the width of the foot. In addition to the technical solutions of the above embodiments, it also has the following technical features.
[0043] The second connecting part 6 is rhomboid in shape.
[0044] The rhombus shape makes the structure more stable and the state easier to maintain.
[0045] Also includes:
[0046] Waterproof membrane 9 is located in the middle of the widened structure. When the widened part is in a contracted state, the waterproof membrane 9 is in a folded state.
[0047] The waterproof membrane 9 is placed in the middle of the widened mesh 4 when it is unfolded, so there will be no physical interference. The waterproof membrane 9 is placed between two widened meshes 4.
[0048] Also includes:
[0049] The heel area 3 is also equipped with a widening mesh 4.
[0050] It also gives the heel a widening function.
[0051] The expansion network 4 is an integrated structure.
[0052] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms fall within the scope of protection of this application.
