Description

TECHNICAL FIELD

[0001] The utility model relates to insole technical field, specifically relate to a comprehensive insole. BACKGROUND

[0002] As an item directly contacting with the foot in daily wear, the rationality of the design of the insole has an important influence on the health of the foot and the comfort of wearing. Most of the existing insoles are designed to be ordinary, which cannot fully meet the mechanical requirements of the human foot during walking, standing and other activities. For example, many insoles cannot well support the arch of the foot, and long-term wearing may cause the arch of the foot to fatigue and collapse, affecting the health of the foot; at the heel part, there is also a lack of reasonable design to disperse pressure and maintain stability, which is easy to cause heel pain and other problems. At the same time, sweat is produced during walking, and the ordinary insole has poor air permeability, which is easy to cause the foot to be hot and humid and breed bacteria.

[0003] Chinese utility model patent (202122913498.9) discloses a balanced insole with multi-dimensional support and shoes thereof, which comprises an insole body, the insole body comprises a sole area, an arch area and a heel area, a support sheet is arranged at the bottom of the arch area and the heel area, the support sheet is arched upward at one side of the arch area along the length direction of the insole body to form a first support surface, the edge of the other side is bent upward to form a second support surface, the support sheet is bent upward at the edge of the heel area to form a U-shaped foot cup, one side of the U-shaped foot cup is connected with the first support surface, and the other side is connected with the second support surface to form a wrapping part, and a parapet is formed on the edge of the wrapping part of the insole body, although the multi-dimensional support structure of the utility model improves the anti-torsion performance, the adaptability design to the hot and humid environment of the foot is still weak.

[0004] In addition, Chinese utility model patent (202120351616.9) discloses an insole structure, a heel support convex part is convexly arranged between the front edge of the calcaneus of the foot and the rear edge of the cuneiform bone of the insole body, the rear foot is supported by the heel support convex part, and the arch is raised, although the utility model emphasizes the wrapping property of the heel, there is a contradiction between the support structure and the air permeability design, and the closed wrapping may aggravate the accumulation of local heat and humidity.

[0005] In summary, the existing technology only considers a single factor and solves a single problem, and does not comprehensively consider the overall flow of gas in the shoe, the overall comfort, the stability and the wrapping property when the insole is located inside the shoe sole during walking. UTILITY MODEL CONTENTS

[0006] To solve the above problems, the utility model provides a comprehensive insole.

[0007] This utility model is implemented in the following manner: a comprehensive insole, the insole including an insole body, the insole body corresponding to the toes, forefoot, arch, and heel of the foot as a toe area, forefoot area, arch area, and heel area, respectively. The toe area is provided with multiple ventilation holes penetrating the insole body. The upper surface of the arch area is provided with a protrusion that fits the arch. The edges of the arch area and the heel area extend upward to form a foot cup. The foot cup includes an inner edge supporting the inner side of the foot and an outer edge supporting the outer side of the foot. The inner edge is higher than the outer edge, and the inner edge and the outer edge are smoothly connected by a rear edge. The lower surface of the heel area is provided with a first support piece. The left and right sides of the front side of the first support piece extend to the arch area to form a second support piece and a third support piece. The first support piece, the second support piece, and the third support piece form a U-shaped support piece. The edge of the U-shaped support piece extends upward to fit the inner edge, the outer edge, and the rear edge.

[0008] Furthermore, the ventilation holes are positioned to correspond to the gap between the toes and the forefoot, and the diameter of the ventilation holes is 1~2mm.

[0009] Furthermore, the protrusion is teardrop-shaped or egg-shaped.

[0010] Furthermore, the highest point of the protrusion is 2-3 mm above the insole, and the width of the protrusion is 25-30 mm in the cross-section of the insole.

[0011] Furthermore, the inner edge is higher than the outer edge, with a height difference of 5~6mm.

[0012] Furthermore, the inner edge, outer edge, and rear edge are connected to the heel area in an arc shape.

[0013] Compared to existing technologies, this invention features a protrusion and a foot cup in the arch area to support the arch. During walking, a cavity exists between the insole and the foot. The protrusion and foot cup in the arch area compress the air between the arch and heel and the insole, causing the air to escape. This creates air suction between lifting and lowering the foot, carrying away the warm, moist air from the foot. Since the toes are far from the arch, ventilation holes are provided in the toe area. The toes compress the air, creating suction through the ventilation holes, allowing the air to flow and enabling sweat produced during walking to dissipate promptly, keeping the feet dry and effectively reducing bacterial growth and odor. The protrusion, foot cup, and ventilation holes in the toe area work synergistically to ensure overall airflow within the shoe during walking, improving overall comfort, stability, and support.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] In the description of this utility model, the structure of the insole provided by this utility model is illustrated using the left insole as an example.

[0023] This utility model provides a comprehensive insole, see reference. Figures 1-5The insole includes an insole body, which corresponds to the toes, forefoot, arch, and heel of the foot as a toe area 1, forefoot area 2, arch area 3, and heel area 4, respectively. Multiple ventilation holes 5 are provided between the toe area 1 and the forefoot area 2, penetrating the insole body. A protrusion 6 conforming to the arch is provided on the upper surface of the arch area 3. The edges of the arch area 3 and the heel area 4 extend upwards to form a foot cup 7. The foot cup 7 includes an inner edge 71 supporting the inner side of the foot and an outer edge 72 supporting the outer side of the foot. The inner edge 71 is higher than the outer edge 72. The inner edge 71 and the outer edge 72 are smoothly connected by a rear edge 73. During walking, the body's center of gravity naturally shifts inwards. The higher inner edge 71 better supports the body's center of gravity, making the foot more stable when landing and starting, reducing the occurrence of accidents such as ankle sprains due to instability, and also helping to... To reduce pressure on the outer side of the heel and alleviate heel pain, the integrated foot cup design effectively wraps around the heel, increasing heel stability and preventing ankle sprains. A first support piece 81 is provided on the lower surface of the heel area 4. The left and right sides of the front edge of the first support piece 81 extend from the heel area 4 to the arch area 3, forming a second support piece 82 and a third support piece 83. The second support piece 82 supports the outer side of the foot, and the third support piece 83 supports the inner side of the foot. The first support piece 81, the second support piece 82, and the third support piece 83 form a U-shaped support piece 8, with the opening of the U-shaped support piece facing the foot. The edge of the U-shaped support piece 8 extends upwards to fit against the inner edge 71, the outer edge 72, and the rear edge 73. The edge of the U-shaped support piece 8 is slightly lower than the upper edge of the foot cup, and the inner edge of the U-shaped support piece 8 is higher than the outer edge, effectively wrapping and supporting the heel and arch, enhancing the stability of the heel and arch areas.

[0024] The ventilation holes 5 are positioned corresponding to the gap 9 between the toes and the forefoot, as shown in the figure. Figure 6As shown, this gap serves as a cushioning and flexion / extension area during walking, and is also a high-risk area for sweat accumulation. The pore diameter of the ventilation hole 5 is 1-2mm, preferably 1.2mm. The small round holes greatly enhance the breathability of the front of the insole. By placing the ventilation holes at positions corresponding to the metatarsophalangeal joints of the foot, the high-sweat areas are precisely covered. The toes are one of the areas with the highest concentration of sweat glands on the feet, especially at the base of the big toe. The concentrated ventilation holes can more efficiently expel sweat accumulated between the toes, reducing the feeling of dampness. At the same time, during wear, the toes compress air, creating suction through the ventilation holes, allowing the air to flow and enabling the sweat produced by the feet during walking to dissipate in time, keeping the feet dry and effectively reducing bacterial growth and odor. In addition, the presence of small round holes can also reduce the weight of the insole to a certain extent, making it lighter and more comfortable to wear. In addition, since the insole inevitably bends during walking, but the bending is concentrated in the forefoot area, this invention places the ventilation holes in the toe area to prevent material fatigue and damage at the opening due to repeated bending and stress during use, thus avoiding affecting the overall performance and service life of the insole.

[0025] The protrusion 6 is teardrop-shaped or egg-shaped;

[0026] The highest point of the protrusion 6 is 2-3mm above the insole, and its width is 25-30mm across the insole's cross-section. The protrusion is made of elastic silicone, and its shape matches the natural curve of the human arch. When a user wears shoes with this insole, the protrusion provides strong support to the arch, effectively relieving pressure on the arch during walking and standing, preventing arch fatigue and collapse, and helping to maintain the normal physiological structure and function of the foot with long-term use. During walking, a cavity exists between the insole and the foot. When the foot lands, the protrusion and the foot cup in the arch area compress the air between the arch and heel and the insole, creating air suction between foot movement and landing, causing the air to escape and carrying away the warm, moist air from the foot.

[0027] The inner edge 71 is higher than the outer edge 72, with a height difference of 5-6 mm; this design conforms to the biomechanical characteristics of human walking. During walking, the body's center of gravity naturally shifts inward, and the higher inner heel can better support the body's center of gravity, making the foot more stable when landing and starting, reducing the occurrence of accidents such as ankle sprains caused by instability, and also helping to reduce pressure on the outer side of the heel and relieve heel pain.

[0028] The inner edge 71, outer edge 72 and rear edge 73 are connected to the heel area 4 in an arc shape, which is smooth and conforms to the curve of the human heel. It can fit and effectively support the heel, prevent the heel from moving and causing injury.

[0029] The U-shaped support plate is made of high-strength polyurethane material, possessing excellent rigidity and toughness. The opening of the U-shaped support plate faces the ball of the foot, with both ends extending to the sides of the heel edge of the insole, effectively wrapping and supporting the heel and enhancing heel stability. Furthermore, unlike traditional support plates, this U-shaped support plate does not have an opening at the corresponding heel position. This design allows the U-shaped support plate to provide more comprehensive and continuous heel support, better limiting lateral swaying and excessive rotation of the heel. This helps maintain a stable foot posture during walking, running, and other activities, reducing the risk of ankle sprains and other injuries caused by foot instability. During walking, the U-shaped support plate disperses the impact force on the heel, evenly distributing it across the entire heel area, reducing damage caused by excessive localized pressure and providing reliable cushioning protection for the heel.

[0030] In this embodiment, the insole body is made of soft, breathable, and elastic polyurethane foam. The small round holes at the front end can be directly stamped out during the insole molding process using a mold, ensuring that the size and distribution of the small round holes are uniform. The waist recess protrusion uses pre-formed elastic rubber or silicone components, which are firmly attached to the waist recess area of ​​the insole using glue or hot pressing. The U-shaped support piece at the bottom of the heel can be made using injection molding or stamping processes according to the design size and shape, and then fixed to the bottom of the heel of the insole with glue or screws. The manufacturing process is as follows: First, the main body material of the insole is cut into the corresponding shape according to the designed insole size and shape. Then, small round holes are stamped out at the front end of the insole according to the predetermined position and size. Next, the prepared waist recess protrusion is accurately attached to the waist recess area of ​​the insole, ensuring that the attachment is firm and the position is accurate. For the U-shaped support piece at the bottom of the heel, an installation groove is first opened at the corresponding position at the bottom of the heel of the insole. After the U-shaped support piece is placed into the installation groove, it is fixed with glue or screws to ensure that the U-shaped support piece is tightly bonded to the insole and does not shift. Finally, the finished insoles undergo a quality inspection to ensure that all components are securely installed, meet the design requirements, and are free from obvious flaws and defects.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
