[0002] General shoes are composed of outsole, insole and vamp. The outsole is located at the bottom of the shoe, which is the part directly contacting the ground, mainly having the functions of wear resistance and anti-skid. The vamp is located above the shoe, covering the dorsal of human foot, mainly having the functions of air permeability, covering and wearing stability. The insole is located between the outsole and the vamp, fixed on the top surface of the outsole, providing elastic buffer between human foot and the outsole. When the user walks, the insole and the outsole of the shoe can absorb, buffer and disperse the impact force generated when the foot falls to the ground, achieving the effect of protecting the foot.

[0003] The top surface of the insole of the shoe is provided with a layer of insole to provide comfort for the user. However, the general insole is flat, which is different from the natural curve of the human foot caused by the arch. Therefore, various arch insoles imitating the shape of the foot bottom are sold on the market. The arch insole is made of a single piece and has a curved surface, providing a user with a full foot sole type insole to pad on the top surface of the insole of the shoe, so that the user can reduce the pressure on the arch when wearing the shoe.

[0004] The known full foot sole type arch insole includes a front foot sole part, an arch part and a heel part from front to back, and the support force of the arch part is strengthened, so that the front foot sole, the arch and the heel of the user can fit the arch insole when walking, helping the user to maintain the normal height of the arch and disperse the pressure on the foot, achieving the effect of shock absorption, reducing the stress on the lower limb joints and the spine, and achieving the function of protecting the foot.

[0005] Another commercially available arch insole is a half foot sole type. The front edge of the half foot sole type insole does not extend to the toe of the shoe. When the insole is padded on the insole of the shoe, it is easy to slide and displace on the top surface of the insole of the shoe. Especially when the user is walking, the half foot sole type insole is easy to slide on the insole of the shoe, and the foot bottom of the human body and the insole are easy to slide and displace, which cannot provide corresponding support.

[0006] The present inventor has improved the above-mentioned shortcomings and created a Taiwan Patent No. M651432 arch insole patent. The feature of the patent is that a plurality of anti-skid cushions are formed on the insole by secondary injection molding to achieve the effects of anti-skid and support. Through actual use, the shortcomings of the traditional arch insole are improved, and the comfort of the user stepping is improved. The present inventor further improves the Taiwan Patent No. M651432 patent, so that the arch insole has better elastic support function for the arch. UTILITY MODEL CONTENT

Detailed Implementation

[0029] like Figures 1 to 4 As shown, this utility model provides an insole with anti-slip properties for the forefoot and elastic arch support. The insole has a generally plate-shaped body 100. The shape of the body 100 in the figure roughly resembles the part of the human foot excluding the toes. Taking a semi-forefoot arch support insole as an example, the body 100 corresponds to the shape of the human foot and has a forefoot area 10, an arch support area 20, and a heel area 30. The top surface of the arch support area 20 is an upwardly curved arc, and the bottom surface of the arch support area 20 of the body 100 has an upwardly concave arc portion 201 relative to the forefoot area 10 and the heel area 30. In practice, the shape of the body 100 may conform to the specifications of a full-foot arch support insole; simply extending the front edge of the forefoot area 10 to the area corresponding to the toes is sufficient.

[0030] The main body 100 has a first positioning opening 11 at a position relative to the forefoot area 10, a second positioning opening 21 at a position relative to the arch support area 20, and a third positioning opening 31 at a position relative to the heel area 30; wherein, a forefoot cushioning pad 12 is fixed inside the first positioning opening 11, an arch cushioning pad 22 is fixed inside the second positioning opening 21, and a heel cushioning pad 32 is fixed inside the third positioning opening 31.

[0031] When the insole is placed on the top surface of the shoe midsole and the user presses down on the main body 100, the user's arch presses against the arch support area 20. Through the concave arc portion 201 and the arch cushioning pad 22, the arch support area 20 provides shock absorption and upward elastic support for the user's arch.

[0032] Simultaneously, the user's forefoot presses against the forefoot cushioning pad 12 and the heel presses against the heel cushioning pad 32, allowing the sole of the foot to contact the top surfaces of the forefoot cushioning pad 12 and the heel cushioning pad 32 respectively, providing anti-slip function. The forefoot cushioning pad 12 and the heel cushioning pad 32 are simultaneously pressed down by the user's weight, causing the bottom surfaces of the forefoot cushioning pad 12 and the heel cushioning pad 32 to fit tightly against the top surface of the shoe midsole. This allows the forefoot and heel of the user's foot to integrate with the shoe through the anti-slip and cushioning effects between the forefoot cushioning pad 12 and the heel cushioning pad 32 and the shoe midsole, effectively improving the comfort of wearing the shoe and preventing the sole of the foot from slipping relative to the shoe midsole during walking.

[0033] In practice, the bottom surface of the main body 100 that contacts the midsole of the shoe can be further provided with anti-slip texture (not shown in the figure), and the bottom surface of the forefoot cushioning pad 12 and / or the heel cushioning pad 32 is respectively provided with transverse anti-slip ridges 321, which have the function of enhancing the anti-slip effect between the auxiliary insole and the midsole of the shoe.

[0034] When each positioning opening is implemented, the first positioning opening 11 is set in accordance with the shape of the human forefoot and is located at the position corresponding to the human forefoot. Its outline is generally a long arc extending laterally, so that the forefoot cushioning pad 12 fixed to the first positioning opening 11 is supported on the human forefoot, so that the forefoot cushioning pad 12 provides anti-slip and cushioning effect between the human forefoot and the shoe midsole.

[0035] When the second positioning opening 21 is implemented, it is composed of a front arc-shaped edge 211 near the forefoot area 10 and a rear arc-shaped edge 212 near the heel area 30. The arc of the front arc-shaped edge 211 is greater than that of the rear arc-shaped edge 212, and the two ends of the front arc-shaped edge 211 and the rear arc-shaped edge 212 are connected to each other to form an egg-shaped outline. This allows the arch cushioning pad 22 fixed to the second positioning opening 21 to be supported on the arch of the human foot. In addition, the upper concave arc portion 201 on the bottom surface of the arch support area 20 of the body 100 is designed so that the arch cushioning pad 22 can provide upward elastic support and shock absorption for the human foot arch.

[0036] When the third positioning opening 31 is implemented, it is set at the position corresponding to the shape of the human heel, in accordance with the shape of the human heel. It is composed of a straight edge 311 near the arch support area 20 and a U-shaped edge 312 near the rear edge of the body 100. The two ends of the U-shaped edge 312 and the straight edge 311 are connected to each other, so that the heel cushioning pad 32 fixed to the third positioning opening 31 is supported on the human heel, so that the heel cushioning pad 32 provides anti-slip and cushioning effect between the human heel and the midsole of the shoe.

[0037] In manufacturing, the forefoot cushioning pad 12, arch cushioning pad 22, and heel cushioning pad 32 can be filled and fixed into the corresponding first, second, and third positioning openings 11, 21, and 31 respectively by secondary injection molding. To enhance the stability between each cushioning pad and each positioning opening, interlocking annular grooves and protruding rings can be provided between them to prevent the cushioning pads from falling out of their respective positioning openings. Of course, it is also possible that the forefoot cushioning pad 12, arch cushioning pad 22, and heel cushioning pad 32 can be manufactured separately and then assembled and fixed into the first, second, and third positioning openings 11, 21, and 31 respectively.

[0038] Furthermore, the top surfaces of the forefoot cushioning pad 12, the arch cushioning pad 22, and the heel cushioning pad 32 protrude from the top surface of the main body 100, and the top surfaces of the forefoot cushioning pad 12 and the arch cushioning pad 22 are convex arc surfaces, so that the thickness of the forefoot cushioning pad 12 and the arch cushioning pad 22 is slightly greater than the thickness of the main body 100, which can increase the cushioning effect when the user steps on the cushion.

[0039] In addition, a magnet 40 is provided on the top surface of the main body 100 between the arch cushioning pad 22 and the heel cushioning pad 32, so that the user's foot can come into contact with the magnet 40, thereby promoting blood circulation in the foot.

[0040] It is worth mentioning that, in order to ensure that the material of the body 100 is hard enough to support the weight of the human body without causing the concave arc portion 201 to collapse, and to ensure that the material elasticity of the forefoot cushioning pad 12, the arch cushioning pad 22, and the heel cushioning pad 32 can provide cushioning and anti-slip functions, the body 100, the forefoot cushioning pad 12, the arch cushioning pad 22, and the heel cushioning pad 32 can be made of materials with different hardness. For example, the material of the body 100 can be plastic with a certain hardness and elasticity.

[0041] In addition, during implementation, a gradually rising limiting edge 101 extends outward from both sides and the periphery of the heel area 30 of the main body 100 to conform to the surrounding area of ​​the user's foot. In order to strengthen the strength of the limiting edge 101, a plurality of reinforcing ribs 60 can be provided on the bottom surface of the limiting edge 101 to strengthen its structural strength and make the limiting edge 101 less prone to deformation.

[0042] As mentioned above, the forefoot cushioning pad 12, the arch cushioning pad 22, and the heel cushioning pad 32 are relatively soft and made of materials such as silicone, rubber, or latex that have anti-slip and cushioning elasticity. In addition, considering the breathability of the insole, the body 100 is provided with a plurality of ventilation holes 50 in positions other than the first, second, and third positioning openings 11, 21, and 31, so as to improve the breathability of the user's shoes through these ventilation holes 50.

[0043] The above-described embodiments and accompanying drawings are merely illustrative examples of preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any embodiments that are similar or identical to the purpose, structure, device, or features of the present utility model shall fall within the patent scope of the present utility model.
