[0019] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0020] See also Figure 1-3As shown, the utility model discloses an insole with load reduction, shock absorption and arch support functions, comprising a body 1 made of an Osole material, so that the insole has the functions of moisture absorption, quick drying and antibacterial, a first pad 2 protruding from the body is provided at the sole of the foot on the lower surface of the body 1, a second pad 3 is provided at the heel of the lower surface of the body 1, and a hard support pad 4 is also provided on the lower surface of the body 1, the support pad 4 surrounds the heel from the inner side of the arch and extends to the outer side of the arch, the support pad 4 is arranged around the outer peripheral side of the second pad 3, and the second pad 3 is arranged protruding relative to the support pad 4. The first pad 2 and the second pad 3 are arranged on the lower surface of the insole body 1, and the first pad 2 protrudes from the body 1, and the second pad 3 protrudes from the support pad 4, so when the insole is used, the first pad 2 first contacts the ground through the shoes relative to the body 1, and the second pad 3 first contacts the ground through the shoes relative to the support pad 4, the first pad 2 and the second pad 3 can absorb the reaction force of the ground acting on the insole, thereby absorbing the energy during exercise, and achieving the effect of energy absorption and load reduction. In addition, the second pad portion 3 protruding from the support pad 4 can absorb a portion of the energy first, reduce the force applied to the hard support pad 4 , and have a certain protective effect on the support pad 4 .

[0021] The side of the rear half of the body 1 is bent upward at a certain angle to form a wrapping portion 10, and the support pad 4 also has a certain bend. Specifically, the inner side of the support pad 4 extends downward to the lower surface of the body 1, and the outer side of the support pad 4 extends upward along the wrapping portion 10 to the side of the body 1. When in use, it can provide support for the outer side of the rear half of the foot, thereby providing sufficient support for the arch and heel of the foot, and has the function of stabilizing the foot support to prevent side slipping and spraining. It can play a role of balanced support on soft ground, prevent sports injuries, and reduce sports fatigue. The support pad 4 is made of hard EVA material, which provides stable support for the arch and heel of the foot, thereby preventing the impact on the knee joint caused by running or jumping.

[0022] The end portion 40 of the support pad 4 located on the inner side of the arch is located in the area of ​​1 / 3 to 1 / 2 of the front end of the body, so as to provide sufficient support for the arch. The support pad 4 is provided with a plurality of through holes 41, and the through holes 41 are arranged at intervals on the inner side of the arch. Since the support pad on the inner side of the arch is relatively wide, the hard support pad is not easy to deform, resulting in excessive hardness of the insole at this location, which will reduce the comfort of the insole. The force at this location is relatively small relative to the heel, so the hardness requirement at this location is also smaller. The provision of a through hole at this location can, on the one hand, make the support pad 4 at this location easier to deform, and achieve a balance between providing support to the arch and absorbing energy. On the other hand, it can play a role of ventilation, which is conducive to the deodorization of the insole.

[0023] In this example, the through hole 41 is a rectangular hole. In other embodiments, the through hole 41 may also be in other shapes, such as a wavy shape, a long strip shape, or a circle.

[0024] See also Figure 3As shown, the first pad 2 is oval in shape and is located at the sole of the foot and close to one end of the arch. More specifically, it is located at about one-third of the forefoot, which is exactly the position where the sole of the foot first touches the ground. Providing the first pad 2 here can prevent the impact of the forefoot from being absorbed and prevent joint wear.

[0025] The first pad 2 is made of high elastic material, the second pad 3 is made of energy absorbing material, the first pad 2 and the second pad 3 are both made of polyurethane foam material, the density of the first pad 2 is less than the density of the second pad 3, so that the polyurethane foam material forming the first pad 2 has high elasticity, the polyurethane foam material forming the second pad 3 has energy absorbing performance, and the first pad 2 is softer than the second pad 3. The first pad 2 makes the forefoot of the insole softer, and its high elasticity can be used to reduce impact, improve sports performance, and reduce fatigue. The second pad 3 makes the heel of the insole, especially the center of gravity of the heel, have the effects of shock absorption, pressure reduction, energy absorption and load reduction. After testing, the second pad 3 of the utility model can absorb about 90% of the impact, reduce damage to the knees, relieve fatigue, and provide sufficient energy feedback for walking and running.

[0026] The lower surface of the front end of the body 1 is provided with a size line 13. According to different sizes, the user can cut the insole along the corresponding size line to adapt the insole to different sizes. Too many sizes will reduce the adaptability of the insole, so each insole is provided with three consecutive sizes, such as 37 / 38 / 39 or 40 / 41 / 42. The user can choose different insoles to cut according to their own situation.

[0027] The lower surface of the body 1 is also provided with a diamond-shaped anti-skid checkered pattern 11, which grips the ground and prevents slipping, increases friction, avoids movement with exercise, and is conducive to maintaining a stable state of movement.

[0028] See also Figure 2 As shown, the upper surface of the body 1 is provided with a plurality of anti-skid protrusions 12 made of silica gel, which cooperate with the anti-skid checkered pattern 11 on the lower surface of the body to increase the friction of the insole.

[0029] The upper surface of the body 1 is covered with a breathable layer and a fabric layer containing graphene. The shapes of the breathable layer and the fabric layer are the same as those of the body. The breathable layer is provided with a plurality of air holes, which are conducive to the timely discharge of foot sweat, achieving the effects of breathability, deodorization and moisture resistance. The fabric layer contains graphene, which can have an antibacterial effect. In other embodiments, the fabric layer covering the upper surface of the body 1 can also be made of fine velvet, which has the functions of anti-slip, quick drying and antibacterial.

[0030] The utility model has the following advantages:

[0031] 1. The second pad 3 at the heel is made of energy-absorbing material, which has a good effect in absorbing the impact of sports. During the research and development test stage, it was measured that it can instantly absorb 90% of the impact of the human body during exercise, prevent knee joint injuries, and reduce sports fatigue.

[0032] 2. The first pad part 2 at the forefoot is made of a highly elastic material. When the human body lands at the moment of movement, the highly elastic material rebounds, making the movement easier and reducing the degree of fatigue.

[0033] 3. The support pads 4 at the middle waist and heel are made of hard EVA material. When the human body walks in relatively harsh and complex environments such as beaches and jungles, it increases the stable support function, prevents side falls, and reduces sports fatigue.

[0034] 4. The overall insole is made of antibacterial, quick-drying and anti-slip materials, which can effectively inhibit problems such as athlete's foot, blisters, odor, etc. caused by bacterial infection.

[0035] The insole of the utility model is suitable for various sports, such as parachuting, walking, running, jumping, playing ball and other high-intensity sports, and can absorb the impact energy during the sports to achieve the energy absorption and load reduction effect of sports cushioning, thereby protecting the foot and leg joints. In addition, it is also suitable for daily use.

[0036] Although the present invention is specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that the remaining undescribed portions are prior art, and that various changes made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims shall fall within the scope of protection of the present invention.
