Description

Technical Field

[0001] This utility model relates to the field of shoe sole technology, specifically to a composite shoe sole. Background Technology

[0002] The sole is the foundation of a shoe. It comes into direct contact with the ground and bears the weight of the body. The comfort of the sole is one of the key indicators of shoe quality, as it directly affects the wearer's health and walking experience. A comfortable sole is usually made of soft and highly elastic materials that can effectively absorb the impact generated during walking or exercise, reducing pressure on the feet and joints. At the same time, the design of the sole should also consider support and stability to ensure sufficient support during walking. The design and materials of the sole play a crucial role in the comfort, wear resistance, slip resistance, and support of the shoe.

[0003] Publication number CN106473316A discloses a breathable shoe sole, including a sole body with an air bladder and a ventilation tube. The air bladder is located at the rear end of the body, and its side wall has an air inlet and an air outlet. An air inlet one-way valve is installed in the air inlet, and an air outlet one-way valve is installed in the air outlet. The ventilation tube is located on both sides of the body, with one end connected to the air outlet and the other end extending to the front end of the body. The breathable shoe sole utilizes a separate air inlet and outlet structure, with the air inlet allowing unidirectional air intake and the air outlet allowing unidirectional air exhaust. This allows fresh airflow to be output at the front end of the sole when the air bladder is squeezed during natural walking. This technology has good breathability. However, during use, the heel of the sole bears most of the weight, and the lack of good support and shock absorption at the heel results in insufficient comfort. Therefore, this technology still has room for improvement. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a composite shoe sole to address the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite shoe sole, comprising a sole body, characterized in that: a first mounting cavity is formed on the surface of the sole body; the sole body is divided into a forefoot portion, an arch portion, and a heel portion from the toe to the heel; a second mounting cavity is provided within the heel portion of the first mounting cavity; a full-length cushioning core layer is embedded within the first mounting cavity; an elastic heel is provided at the bottom of the full-length cushioning core layer; the elastic heel is placed within the second mounting cavity; a warm pad is laid above the full-length cushioning core layer within the first mounting cavity; and several through holes are provided at the elastic heel, each through hole being engraved with a cushioning core.

[0006] Using the above technical solution, the sole body has a first mounting cavity for the installation of the full-length cushioning core layer, and a second mounting cavity is provided at the heel to facilitate the installation of the elastic heel of the full-length cushioning core layer, providing good support for the foot and improving overall comfort. At the same time, a warm pad is provided above the full-length cushioning core layer to fit the foot, and several through holes are provided at the elastic heel, each of which is engraved with cushioning core, which can provide strong support for the user's heel base during walking and improve the user's comfort.

[0007] The aforementioned composite sole can be further configured such that: both the bottom of the forefoot and the bottom of the heel are provided with anti-slip zones, the anti-slip zones are divided into a first anti-slip zone and a second anti-slip zone, the surface of the first anti-slip zone is provided with a plurality of anti-slip strips axially, the second anti-slip zone is provided with a plurality of anti-slip blocks, the anti-slip blocks include a first anti-slip surface and a second anti-slip surface, the surface of the first anti-slip surface is provided with a frosted anti-slip surface, the surface of the second anti-slip surface is provided with a plurality of anti-slip protrusions, and a plurality of anti-slip grooves are formed between the anti-slip blocks.

[0008] By adopting the above technical solution, the anti-slip strip design in the first anti-slip zone and the frosted anti-slip surface and anti-slip protrusions in the second anti-slip zone increase the friction between the sole and various ground surfaces, effectively preventing slipping and falling, and improving the safety of walking and sports. By dividing the anti-slip zone into two areas and designing different anti-slip structures according to the functional needs of each area, better adaptation to different walking stages and ground conditions is achieved. Whether it is a city street, a mountain path or a wet and slippery road surface, it can provide reliable grip. At the same time, the anti-slip groove design strips make walking easier to bend, and the anti-slip grooves have a transition function when bending, making bending smoother.

[0009] The aforementioned composite sole can be further configured such that: a third mounting cavity is provided inside the elastic heel, a plurality of elastic columns are provided inside the third mounting cavity, the elastic columns include mounting columns, elastic blocks that can move axially within the mounting columns are provided at both ends of the mounting columns, and springs are provided between the elastic blocks.

[0010] Using the above technical solution, a third mounting cavity is provided within the full-length cushioning core layer. An elastic column is installed in the third mounting cavity, and the elastic blocks at both ends of the elastic column are connected by springs to make the elastic column elastic. This provides strong elasticity to the full-length cushioning core layer within the third mounting cavity, improving the comfort of the user's heel.

[0011] The aforementioned composite sole can be further configured as follows: the edges at both ends of the elastic column extend inward to form baffles; the elastic block includes an elastic part that abuts against the third mounting cavity; an abutment plate is arranged around the bottom of the elastic part; the center of the baffle is provided with a connecting hole for the elastic part to pass through; the abutment plate is placed inside the elastic column and abuts against the baffle; and the end of the abutment plate facing the spring is provided with a positioning plate for positioning and mounting the spring.

[0012] By adopting the above technical solution, an effective limiting structure for the elastic block is formed by setting inwardly extending baffles at both ends of the elastic column, ensuring that the elastic block can remain stable under force and is not prone to displacement or deformation. The abutment plate arranged around the bottom of the elastic part is in close contact with the baffle, further enhancing the fixing effect of the elastic block. The connecting hole in the center of the baffle provides the necessary space for the elastic part to move, allowing it to deform flexibly under pressure, thereby effectively absorbing impact force and improving wearing comfort. The abutment plate is provided with a positioning plate for spring positioning and installation, so that the spring can be accurately and stably installed in the predetermined position, ensuring the normal operation and long-term durability of the spring.

[0013] The aforementioned composite sole can be further configured such that the full-length cushioning core layer has several breathable holes located at the foot.

[0014] Using the above technical solution, the ventilation holes allow air to circulate inside the shoe, which helps to expel moisture and heat, keeping the inside of the shoe dry. This makes it suitable for long-term wear or in warm environments, and can significantly reduce discomfort caused by heat and humidity.

[0015] The beneficial effects of this utility model are as follows: The sole body has a first mounting cavity for the installation of the full-length cushioning core layer, and a second mounting cavity is provided at the heel to facilitate the installation of the elastic heel of the full-length cushioning core layer, providing good support for the foot and improving overall comfort. At the same time, a warm pad is provided above the full-length cushioning core layer to fit the foot, and several through holes are provided at the elastic heel, each of which is engraved with cushioning core, providing strong support for the user's heel base during walking.
