Description

Technical Field

[0001] This utility model relates to the field of shoe insole technology, specifically to a pad-type cushioning shoe insole. Background Technology

[0002] Insoles are components placed inside shoes to enhance comfort and support the feet. Insoles typically conform to the shape of the foot and come into direct contact with the ball of the foot. Their core function is to relieve pressure during walking by distributing stress points and filling gaps within the shoe, thus reducing foot fatigue. Specifically, the cushioning and shock absorption functions of insoles effectively absorb the impact generated during walking or running, reducing pressure on the feet, knees, and spine, and improving overall wearing comfort.

[0003] Because the heel and forefoot bear the most weight when walking or running, although some insoles can increase softness by changing the material itself, this method changes the overall softness of the insole and makes it difficult to increase the softness or elasticity of the heel area according to needs while ensuring support, resulting in limited functionality. Utility Model Content

[0004] The purpose of this invention is to provide a pad-type cushioning insole to address the defects and shortcomings of the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pad-type cushioning insole, comprising an insole body, an arch support piece disposed on the lower end face of the insole body, a heel groove formed on the lower end face of the insole body and the arch support piece, a replaceable pad detachably disposed on the lower end face of the insole body within the heel groove, and a forefoot cushioning piece disposed on the lower end face of the insole body.

[0006] A further improvement is that: the insole body has a transverse arch-shaped bulge at the forefoot, and the lower end of the insole body, at the end of the transverse arch-shaped bulge, has a groove for the transverse arch area, and a replaceable pad is detachably installed in the groove for the transverse arch area on the lower end of the insole body.

[0007] A further improvement is that a fleece surface is fixedly provided on the lower end face of the insole body within the heel groove, and a bristle surface is fixedly provided on the replacement pad, with the fleece surface and the bristle surface being bonded together.

[0008] A further improvement is that a fleece surface is fixedly provided on the lower end face of the insole body within the groove of the transverse arch area, and a bristle surface is fixedly provided on the replacement pad, with the fleece surface and the bristle surface being bonded together.

[0009] A further improvement is that the replacement gasket includes an inner gasket and an outer ring gasket, both of which are provided with bristle surfaces.

[0010] A further improvement is that the replacement gasket is an EVA gasket, a sponge gasket, a supercritical foam gasket, a silicone gasket, or a rubber gasket.

[0011] A further improvement is that the arch support plate is made of nylon.

[0012] A further improvement is that the forefoot cushioning sheet is an EVA sheet, a sponge sheet, a supercritical foam sheet, a silicone sheet, or a rubber sheet.

[0013] A further improvement is that the upper end face of the outer ring gasket is provided with a side groove, the side groove being close to the end face of the inner gasket, and the upper end face of the inner gasket is provided with a side extension, the side extension being in clearance fit with the side groove.

[0014] A further improvement is that the forefoot cushioning plate is provided with a metatarsophalangeal joint decompression zone.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are as follows: the slot opened at the heel position of the arch support plate can provide a cushioning space for the heel while the arch support plate provides support for the arch position. It can improve the flexibility of the heel while ensuring support. The forefoot cushioning plate can buffer the pressure on the forefoot area and improve the flexibility of the forefoot. When it is necessary to improve the softness or elasticity of the heel area, a flexible pad or elastic pad of appropriate material can be selected and installed in the heel slot according to the flexibility requirements. Thus, the softness or elasticity of the heel is improved by the softness or elasticity of the flexible pad or elastic pad itself. It has multiple functions.

[0016] Further benefits: The transverse arch arch design can distribute pressure when the forefoot is under pressure by deforming the transverse arch arch, thereby improving the cushioning effect of the forefoot. When the replacement pad is removed from the groove in the transverse arch area, the deformation space of the transverse arch arch increases, thereby increasing the cushioning effect and the flexibility of the forefoot.

[0017] Further benefits: The burr and napped surfaces facilitate the installation or removal of replacement pads from the heel slot and transverse arch slot.

[0018] Further benefits: The inner and outer ring pads can be installed in the heel groove and transverse arch groove as needed to achieve different levels of softness. When only the inner pad is installed in the heel groove and transverse arch groove, a gap is formed between the inner pad and the groove. This gap disperses the pressure generated on the sole of the foot, thereby improving the softness and cushioning effect. When only the outer ring pad is installed in the heel groove and transverse arch groove, a gap is formed between the inner ring of the outer ring pad and the groove. This gap disperses the pressure generated on the sole of the foot, causing the pressure to deform towards the inner ring of the outer ring pad, thus changing the softness and cushioning effect.

[0019] Further benefits: When changing the size of the insole, the inner and outer ring pads can be installed according to the size of the insole. For example, when changing to a small insole, simply install the inner pad in the heel groove and the groove in the transverse arch area. When changing to a large insole, after splicing the inner and outer ring pads, attach the extra outer ring pad to the replacement pad. The installation is done according to the size of the insole through the ring setting, eliminating the need to purchase replacement pads of the same size separately.

[0020] Further benefits: The material of the replacement pad can be changed as needed, and different degrees of cushioning and softening effects can be achieved by using different materials with varying degrees of softness.

[0021] Further benefits: When the inner and outer ring pads need to be installed in the heel groove and the transverse arch groove, first install the outer ring pad in the heel groove and the transverse arch groove, then install the inner pad in the inner ring position of the outer ring pad, and press the annular extension into the side groove. Through the adhesive fit of the bristles and the pile, and the setting of the side extension in the side groove, the inner pad further presses the outer ring pad into the heel groove and the transverse arch groove, further preventing the outer ring pad from curling up from the periphery of the inner pad.

[0022] Further benefits: The metatarsophalangeal joint decompression zone can relieve pressure on the metatarsophalangeal joints at the bottom of the foot, improving the flexibility of the foot in the metatarsophalangeal joint area. Attached Figure Description

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0031] See Figures 1 to 5 As shown, the technical solution adopted in this specific embodiment is: a pad-type cushioning insole, including an insole body 1, an arch support piece 2 disposed on the lower end surface of the insole body 1, a heel groove 3 formed on the lower end surface of the insole body 1 and the arch support piece 2, a replaceable pad 4 detachably disposed on the lower end surface of the insole body 1 within the heel groove 3, and a forefoot cushioning piece 5 disposed on the lower end surface of the insole body 1. The arch support piece 2 is disposed at the lower end of the insole body 1 at the arch position.

[0032] The insole body 1 has a transverse arch 6 located at the forefoot. A groove 7 for the transverse arch area is formed on the lower end of the insole body 1, at the end of the transverse arch 6. A replaceable pad 4 is detachably installed within the groove 7 on the lower end of the insole body 1. The replaceable pad 4 can be adjusted to provide different levels of softness, shock absorption, or resilience in the heel or transverse arch area according to the needs of different individuals. Alternatively, the pad can be removed to create a pressure-reducing effect in the cavity, thereby alleviating pain in the heel or transverse arch.

[0033] Because some people are intolerant to transverse arch support (and will feel pain), but for many people with flat feet and plantar fasciitis, transverse arch support is necessary. Therefore, this group can consider removing the replacement pad 4 during exercise. The arch of the transverse arch 6 and the opening of the groove 7 in the transverse arch area can relieve pain in the transverse arch area. When wearing the shoes daily, the replacement pad 4 can be installed in the groove 7 in the transverse arch area to provide support for the transverse arch. The support for the transverse arch can be replaced by a replacement pad of hard, soft or elastic size.

[0034] A fleece surface 8 is fixedly disposed on the lower end face of the insole body 1 within the heel groove 3, and a bristle surface 9 is fixedly disposed on the replacement pad 4. The fleece surface 8 and the bristle surface 9 are bonded together. The fleece surface 8 is bonded to the lower end face of the insole body 1 within the heel groove 3 using adhesive. The bristle surface 9 is bonded to the replacement pad 4 using adhesive.

[0035] A fleece surface 8 is fixedly disposed on the lower end face of the insole body 1 within the groove 7 in the transverse arch area. A bristle surface 9 is fixedly disposed on the replacement pad 4. The fleece surface 8 and the bristle surface 9 are bonded together. The fleece surface 8 is bonded to the lower end face of the insole body 1 within the groove 7 in the transverse arch area using adhesive. The bristle surface 9 is bonded to the replacement pad 4 using adhesive.

[0036] The replacement gasket 4 includes an inner gasket 41 and an outer ring gasket 42, both of which have bristle surfaces 9. The inner gasket 41 and the outer ring gasket 42 are fitted with a clearance fit.

[0037] The replacement gasket 4 is an EVA gasket, a sponge gasket, a supercritical foam gasket, a silicone gasket, or a rubber gasket.

[0038] The arch support piece 2 is a nylon sheet. The arch support piece 2 is installed on the lower end surface of the insole body 1 by means of heat pressing, adhesive, or glue.

[0039] The forefoot cushioning plate 5 is an EVA sheet, a sponge sheet, a supercritical foam sheet, a silicone sheet, or a rubber sheet. The forefoot cushioning plate 5 is fixedly installed on the insole body 1 with glue or adhesive.

[0040] The outer ring gasket 42 has a side groove 10 on its upper end face, which is close to the end face of the inner gasket 41. The inner gasket 41 has a side extension 11 on its upper end face, which is clearance-fitted with the side groove 10. The side groove 10 and the outer ring gasket 42 are integrally formed. The side extension 11 and the inner gasket 41 are integrally formed.

[0041] The forefoot cushioning plate is provided with a metatarsophalangeal joint decompression zone 12.

[0042] The working principle of this utility model is as follows: The slot opened at the heel position of the arch support plate 2 can provide a cushioning space for the heel while providing support for the arch position. It can improve the flexibility of the heel while ensuring support. The forefoot cushioning plate 5 can buffer the pressure on the forefoot area and improve the flexibility of the forefoot. When it is necessary to improve the softness or elasticity of the heel area, a flexible pad or elastic pad of appropriate material can be installed in the heel slot 3 according to the flexibility requirements. The softness or elasticity of the heel can be improved by the softness or elasticity of the flexible pad or elastic pad itself. It has multiple functions.

[0043] The transverse arch arch 6 can disperse pressure when the forefoot is compressed by deforming the transverse arch arch 6, thereby improving the cushioning effect of the forefoot. When the replacement pad 4 is removed from the groove 7 in the transverse arch area, the deformation space of the transverse arch arch 6 increases, thereby increasing the cushioning effect of pressure and the flexibility of the forefoot.

[0044] The bristle side 9 and the napped side 8 facilitate the installation or removal of the replacement pad 4 from the heel slot 3 and the transverse arch area slot 7.

[0045] The inner pad 41 and the outer ring pad 42 can be installed in the heel groove 3 and the transverse arch groove 7 as needed to achieve different softness effects. When only the inner pad 41 is installed in the heel groove 3 and the transverse arch groove 7, a gap is formed between the inner pad 41 and the heel groove 3 and the transverse arch groove 7. This gap can disperse the pressure generated on the sole of the foot, thereby improving the softness and cushioning effect. When only the outer ring pad 42 is installed in the heel groove 3 and the transverse arch groove 7, a gap is formed between the inner ring of the outer ring pad 42 and the heel groove 3 and the transverse arch groove 7. This gap can disperse the pressure generated on the sole of the foot, causing the pressure to deform towards the inner ring of the outer ring pad 42, thereby changing the softness and cushioning effect.

[0046] When it is necessary to install the inner pad 41 and the outer ring pad 42 in the heel groove 3 and the transverse arch groove 7, first install the outer ring pad 42 in the heel groove 3 and the transverse arch groove 7, and then install the inner pad 41 in the inner ring position of the outer ring pad 42, and press the annular extension into the side groove 10. Through the adhesive cooperation of the bristles and the pile, and the setting of the side extension 11 in the side groove 10, the inner pad 41 further presses the outer ring pad 42 into the heel groove 3 and the transverse arch groove 7, further preventing the outer ring pad 42 from curling up from the periphery of the inner pad 41.
