[0001] This utility model relates to the field of shoe sole technology, specifically to an ergonomic and breathable shoe sole. Background Technology

[0002] Breathable soles refer to a combination of sole design and materials that allow for good air circulation or water vapor expulsion, with the aim of keeping feet drier and more comfortable and reducing stuffiness and other problems.

[0003] For example, Chinese patent CN220403248U discloses a breathable shoe sole, including a sole body and a step-concave surface formed on the upper surface of the sole body. The step-concave surface has an internal ventilation chamber corresponding to the position of the foot, and the sole body has a deformation power chamber communicating with the outside world corresponding to the position of the heel. A branch-and-vein ventilation structure is provided between the power chamber and the internal ventilation chamber. The branch-and-vein ventilation structure forms a multi-level ventilation channel, which connects the internal ventilation chamber and the power chamber. The multi-level ventilation channel includes a primary ventilation channel and at least two secondary ventilation channels connecting the primary ventilation channel. By referencing the branch-and-vein structure of trees, gas can be evenly and smoothly guided outward, thereby achieving rapid air exhaust in the sole and thus achieving better breathability and air expulsion.

[0004] Existing shoe soles are prone to deformation during prolonged walking or standing. Furthermore, during exercise, especially when wearing shoes for extended periods, air circulation inside the shoes is poor, preventing the timely dissipation of heat and moisture generated by the feet, leading to stuffy and uncomfortable feet. Utility Model Content

[0005] The purpose of this invention is to provide an ergonomic and breathable sole to solve the problems in the prior art where existing soles are prone to deformation during long-term walking or standing, and where air does not circulate inside the shoe during exercise, especially during exercise or long-term wear.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ergonomic and breathable shoe sole, comprising a bottom layer, wherein a padding layer is fixedly connected to the top of the bottom layer, and the bottom layer and the padding layer form the shoe sole body; The curved surfaces formed by the bottom layer and the top of the padding layer conform to the contour of the human foot. A sandwich layer is fixedly connected between the bottom layer and the padding layer. A second shape retaining plate with an annular structure is fixedly connected between the sandwich layer and the padding layer. A first shape retaining plate with an annular structure is fixedly connected between the sandwich layer and the bottom layer. Both the first shape retaining plate and the second shape retaining plate are made of carbon fiber material.

[0007] Preferably, the top of the bottom layer is provided with a first mounting groove of an annular structure, and the first shape retaining plate is fixedly connected inside the first mounting groove. The top of the side of the interlayer facing the pad layer is provided with a second mounting groove of an annular structure, and the second shape retaining plate is fixedly connected inside the second mounting groove.

[0008] Preferably, the padding layer includes a fixing ring, a breathable pad with a mesh structure is fixedly connected inside the fixing ring, and an isolation pad that completely covers the breathable pad is fixedly connected on the fixing ring, the isolation pad being a breathable woven material.

[0009] Preferably, the bottom of the padding layer is provided with a fixing groove, the fixing groove is located below and aligned with the breathable pad, and the interlayer is fixedly connected to the inside of the fixing groove.

[0010] Preferably, the bottom layer has a groove at the top and a first mounting groove is provided at the bottom of the groove. The interlayer is fixedly connected to the groove. The interlayer includes an airtight sleeve. The top of the airtight sleeve has uniformly distributed through holes, and the through holes are located inside the second shape retaining plate.

[0011] Preferably, an elastic pad is fixedly connected inside the airtight sleeve, the elastic pad is made of an elastic porous material, and the airtight sleeve has equidistant side through holes on both sides.

[0012] Preferably, the bottom edge of the padding layer is provided with equally spaced upper forming holes, and the top edge of the bottom layer is provided with equally spaced lower forming holes. When the bottom layer and the padding layer are bonded together, the upper forming holes and the lower forming holes are aligned to form vent holes. The vent holes are aligned with the side through holes and connect the inside of the airtight sleeve to the outside.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This type of shoe features an ergonomic and breathable sole. During wear, the foot naturally conforms to the curved surface, achieving initial fit and support. The interlayer between the bottom layer and the padding layer, as well as the first and second shape-maintaining plates connecting the interlayer to the bottom layer and the padding layer, maintain their own ring-shaped structure when the foot is under pressure. This provides support and shaping for the overall sole structure, reduces excessive deformation of various components, and ensures that the sole always maintains a curved surface that conforms to the foot's contour, thereby improving the comfort and stability of the foot when worn. When walking, the foot applies pressure to the padding layer, compressing the air-sealed sleeve and allowing internal air to escape through the side openings and ventilation holes. When the foot is lifted, the elastic pad rebounds, the air-sealed sleeve returns to its original shape, and outside air enters. During this process, the top of the opening at the top of the air-sealed sleeve connects with the ventilation pad, drawing heat and moisture from the ventilation pad into the air-sealed sleeve and expelling it, achieving breathable circulation inside the sole and effectively reducing stuffiness in the feet.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please refer to Figures 1 to 6 The present invention provides the following technical solution: An ergonomic and breathable sole includes a bottom layer 1, a padding layer 2 fixedly connected to the top of the bottom layer 1, and the bottom layer 1 and the padding layer 2 forming the sole body; the curved surface formed by the top of the bottom layer 1 and the padding layer 2 conforms to the contour of the human foot, a sandwich layer 3 is fixedly connected between the bottom layer 1 and the padding layer 2, a second shape retaining plate 7 with an annular structure is fixedly connected between the sandwich layer 3 and the padding layer 2, and a first shape retaining plate 5 with an annular structure is fixedly connected between the sandwich layer 3 and the bottom layer 1, and both the first shape retaining plate 5 and the second shape retaining plate 7 are made of carbon fiber material.

[0018] The bottom layer 1 has a first mounting groove 4 with an annular structure at its top, and a first shape retaining plate 5 is fixedly connected to the inside of the first mounting groove 4. The interlayer 3 has a second mounting groove 6 with an annular structure at its top on the side facing the pad layer 2, and a second shape retaining plate 7 is fixedly connected to the inside of the second mounting groove 6. The pad layer 2 includes a fixing ring 8, a breathable mesh pad 9 is fixedly connected inside the fixing ring 8, and an isolation pad 10 that completely covers the breathable pad 9 is fixedly connected on the fixing ring 8. The isolation pad 10 is made of breathable woven material.

[0019] The bottom of the pad 2 is provided with a fixing groove 11, which is located below and aligned with the breathable pad 9, and the interlayer 3 is fixedly connected to the inside of the fixing groove 11.

[0020] The bottom layer 1 has a groove at the top, and the first mounting groove 4 is located at the bottom of the groove. The interlayer 3 is fixedly connected to the groove. The interlayer 3 includes an airtight sleeve 12. The top of the airtight sleeve 12 has a uniformly distributed through hole top 14, and the through hole top 14 is located inside the second shape retaining plate 7. An elastic pad 15 is fixedly connected inside the airtight sleeve 12. The elastic pad 15 is made of elastic porous material. Both sides of the airtight sleeve 12 have equidistantly distributed side through holes 13. The bottom edge of the pad layer 2 has equidistantly distributed upper forming holes 16, and the top edge of the bottom layer 1 has equidistantly distributed lower forming holes 17. When the bottom layer 1 and the pad layer 2 are attached, the upper forming holes 16 and the lower forming holes 17 are aligned to form a vent hole 18. The vent hole 18 is aligned with the side through holes 13 and connects the inside of the airtight sleeve 12 to the outside.

[0021] The sole consists of a bottom layer 1 and a padding layer 2. The curved surface formed by the bottom layer 1 and the top of the padding layer 2 conforms to the contour of the human foot. When the user steps on the padding layer 2, the foot can naturally conform to the curved surface, achieving initial fit and support.

[0022] Meanwhile, a sandwich layer 3 is fixedly connected between the bottom layer 1 and the padding layer 2. A first shape retaining plate 5 with an annular structure is fixedly connected between the sandwich layer 3 and the bottom layer 1 through a first mounting groove 4. A second shape retaining plate 7 with an annular structure is fixedly connected between the sandwich layer 3 and the padding layer 2 through a second mounting groove 6. Both the first shape retaining plate 5 and the second shape retaining plate 7 are made of carbon fiber material. Carbon fiber material has good structural stability. When the user walks or stands, and the foot exerts pressure on the padding layer 2, the first shape retaining plate 5 and the second shape retaining plate 7 can maintain their own annular structure shape, thereby playing a supporting and shaping role for the overall structure of the sandwich layer 3, the bottom layer 1 and the padding layer 2, reducing excessive deformation of each component due to force, ensuring that the sole body always maintains a curved shape that matches the contour of the human foot, and improving the comfort and stability of the foot when wearing.

[0023] The padding layer 2 includes a fixing ring 8, a mesh structure breathable pad 9, and an isolation pad 10 that completely covers the breathable pad 9. The isolation pad 10 is made of breathable woven material. When the user's foot comes into contact with the isolation pad 10, the heat and moisture generated by the foot can first penetrate through the woven gaps of the isolation pad 10 to the mesh breathable pad 9 below. The mesh structure of the breathable pad 9 can further conduct this heat and moisture, providing a channel for subsequent moisture discharge.

[0024] The interlayer 3 includes an airtight sleeve 12, and an elastic pad 15 of elastic porous material is fixedly connected inside the airtight sleeve 12. The top of the airtight sleeve 12 is provided with a top 14 of through holes that are evenly distributed and located inside the second shape retaining plate 7. The sides are provided with side through holes 13 that are evenly distributed. When the bottom layer 1 and the pad layer 2 are attached, the upper forming hole 16 at the bottom edge of the pad layer 2 is aligned with the lower forming hole 17 at the top edge of the bottom layer 1 to form a vent hole 18. The vent hole 18 is aligned with the side through hole 13 and connects the inside of the airtight sleeve 12 to the outside.

[0025] When a user walks, their feet exert downward pressure on the padding layer 2. This pressure is transmitted through the padding layer 2 to the airtight sleeve 12 of the interlayer 3, causing the airtight sleeve 12 to be compressed and its internal space to shrink. At this time, the air inside the airtight sleeve 12 will enter the aligned ventilation holes 18 through the side through-holes 13 and then be discharged to the outside. When the user lifts their feet and the pressure on the padding layer 2 disappears, the elastic pad 15 inside the airtight sleeve 12 rebounds due to the elastic porous material properties, pushing the airtight sleeve 12 back into place. When the sleeve 12 is restored to its original state, the internal space expands, and outside air will re-enter the air-sealed sleeve 12 through the ventilation holes 18 and the side through holes 13. During this process, the top 14 of the through hole at the top of the air-sealed sleeve 12 can connect with the breathable pad 9 under the padding layer 2. The flow of air inside the air-sealed sleeve 12 can bring the heat and moisture from the breathable pad 9 into the air-sealed sleeve 12, and then exhaust it to the outside through the side through holes 13 and the ventilation holes 18, thereby realizing the breathable circulation inside the sole and reducing the stuffiness of the feet.

[0026] The interlayer 3 is fixedly connected to the bottom layer 1 and the padding layer 2 through the groove at the top of the bottom layer 1 and the fixing groove 11 at the bottom of the padding layer 2. This connection method can ensure that the position of the interlayer 3 is stable during use and avoid displacement due to force.
