Description

Technical Field

[0001] This utility model relates to the field of insole technology, specifically to a high arch support insole. Background Technology

[0002] High arch is a common foot deformity, also known as high arch. It is characterized by an excessively high foot, an excessively high longitudinal arch, which leads to a shortened foot length, claw-shaped toes, Achilles tendon contracture, etc., affecting walking and standing. In severe cases, it can cause foot pain and functional impairment.

[0003] Orthotic insoles are assistive devices used to improve symptoms of high arches by providing extra support and balance to reduce foot discomfort. Specifically, they help reduce foot pressure and alleviate pain by providing additional support and cushioning. For patients with mild high arches, orthotic insoles can improve symptoms and increase the contact area with the sole of the foot, thereby reducing pain, improving walking function, and preventing further development of the deformity.

[0004] In the prior art, a high arch correction insole with corrective function, disclosed in CN207898020U, includes an insole body comprising a forefoot, a midfoot, and a heel. The forefoot and heel, corresponding to the pressure points on the foot, are respectively provided with a first lower groove and a second lower groove. A first high-cushioning energy-absorbing polyurethane pad and a second high-cushioning energy-absorbing polyurethane pad are respectively provided on the first and second lower grooves. The insole body, from top to bottom, consists of a fabric layer, a polyurethane foam material layer, and an EVA layer. The EVA layer, specifically the forefoot and heel, is provided with the first and second high-cushioning energy-absorbing polyurethane pads. This invention has a good arch correction effect and can effectively reduce or avoid fatigue and injury caused by strenuous exercise. However, it still has the following problems: (1) Insufficient forefoot support and anti-slip: The lack of honeycomb cushioning structure and blocking design makes the forefoot easy to slip when walking, and the pressure distribution effect is poor; (2) Poor dynamic adaptability of arch support: It may use a fixed rigidity support structure, which cannot be dynamically adjusted with gait, resulting in limited cushioning effect. Utility Model Content

[0005] The purpose of this invention is to provide a high arch support insole to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high arch support orthotic insole includes: The insole body, and the heel area, arch area and forefoot area provided on the insole body, wherein the heel area and forefoot area are concave; A second polyester elastic pad is adhered to the heel area, and a third polyester elastic pad is distributed around the second polyester elastic pad. Two first polyester elastic pads are adhered to the arch area.

[0007] Preferably, the groove in the heel area is offset inward by 5mm, has a depth of 3mm, and a width of 15mm.

[0008] Preferably, a honeycomb TPU pad is adhered to the bottom of the forefoot area. The honeycomb TPU pad is honeycomb-shaped, with a honeycomb pore diameter of 5mm, a spacing of 2mm between adjacent honeycomb pores, and a depth of 4mm.

[0009] Preferably, the honeycomb TPU pad is located 55mm from the front edge of the insole body and offset 2.5mm from the inside.

[0010] Preferably, a TPU cushioning pad is adhered to the bottom of the heel area.

[0011] Preferably, a TPU blocking pad is adhered to the forefoot area, and the TPU blocking pad has a "V" shaped structure.

[0012] Preferably, the insole body has several air holes distributed inside.

[0013] Preferably, a wavy twist plate is provided on one side of the arch area.

[0014] Preferably, the wavy twisted piece is wavy and distributed along the arch curve of the foot.

[0015] Preferably, the TPU cushioning pad is elliptical in shape.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This invention provides arch support to reduce pressure concentration caused by excessively high arches, while improving overall comfort and preventing problems such as plantar fasciitis. High arches are often accompanied by pressure concentration on the forefoot, so the design needs to distribute pressure reasonably and improve dynamic balance.

[0017] The heel area features an eccentric groove and multi-layer shock absorption design. The groove is 5mm inward from the center, 3mm deep, and 15mm wide. It is paired with a second polyester elastic pad and a third polyester elastic pad around the perimeter. A TPU cushioning pad is added to the bottom. The pressure is distributed through the eccentric groove on the inside to avoid excessive wear or pain in certain areas.

[0018] The forefoot area features a honeycomb TPU pad with a "V"-shaped blocking design. The honeycomb TPU pad has a pore diameter of 5mm, a spacing of 2mm, a depth of 4mm, and an inner offset of 2.5mm. The TPU blocking pad is in a "V" shape, and the honeycomb structure disperses foot pressure through a hollow design, preventing excessive local pressure on the forefoot. The "V"-shaped blocking pad prevents the foot from shifting forward, solving the problem of insufficient anti-slip properties that may exist in the original patent and improving walking stability.

[0019] The arch support features a wavy twisted plate and a double polyester pad design. The wavy twisted plate is distributed along the arch curve, and the peak and trough design achieves dynamic deformation of 0.5-1mm. The double first polyester elastic pad enhances support. Compared with traditional fixed rigid support, the wavy twisted plate adapts to the dynamic changes of the arch during walking through elastic deformation (trough cushioning and peak rigid support), thus improving support comfort.

[0022] 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.

[0023] Please see Figure 1-3 A high arch support insole, comprising: The insole body 1, and the heel area 2, arch area 3, and forefoot area 4 provided on the insole body 1, with the heel area 2 and forefoot area 4 being concave; A second polyester elastic pad 11 is adhered to the heel area 2, and a third polyester elastic pad is distributed around the second polyester elastic pad 11. Two first polyester elastic pads 5 are bonded to the arch area 3.

[0024] In the above technology, the second polyester elastic pad 11 and the third polyester elastic pad evenly distributed around the second polyester elastic pad 11 are used to provide support and shock absorption for the heel and to protect the heel.

[0025] like Figure 1 As shown, the center of the groove in the heel area 2 is offset inward by 5mm, with a depth of 3mm and a width of 15mm.

[0026] In the above technology, through the eccentric design, the pressure on the heel of patients with high arches is biased to the outer side, and the inner groove can balance the pressure.

[0027] like Figure 1 As shown, a honeycomb TPU pad 7 is bonded to the bottom of the forefoot area 4. The honeycomb TPU pad 7 is honeycomb-shaped, with a honeycomb pore diameter of 5mm, a spacing of 2mm between adjacent honeycomb pores, and a depth of 4mm. The honeycomb TPU pad 7 is 55mm away from the front edge of the insole body 1 and offset 2.5mm from the inside.

[0028] In the above technology, the honeycomb structure of the honeycomb TPU pad 7 can provide support for the foot and disperse the force on the honeycomb TPU pad 7, thus providing uniform support and cushioning for the foot.

[0029] like Figure 1 As shown, a TPU cushioning pad 6 is attached to the bottom of the heel area 2. The TPU cushioning pad 6 is oval in shape.

[0030] In the aforementioned technology, the TPU cushioning pad 6 provides additional cushioning support to the heel, further protecting the heel.

[0031] like Figure 1 , Figure 2 As shown, a TPU blocking pad 10 is bonded to the forefoot area 4, and the TPU blocking pad 10 has a "human" shaped structure.

[0032] In the above technology, the TPU blocking pad 10 is used to prevent the foot from sliding forward and to provide cushioning for the sole of the foot.

[0033] like Figure 1 As shown, the insole body 1 has several air holes 8 distributed inside to provide breathability.

[0034] like Figure 1 As shown, a wavy twisted piece 9 is provided on one side of the arch area 3. The wavy twisted piece 9 is wavy and distributed along the arch curve.

[0035] In existing technologies, wave-shaped twisted plates can effectively support high arches by increasing the contact area and elastic deformation, but the wave parameters and material hardness need to be optimized; the wave trough area (thin part) deforms slightly during walking to provide cushioning; the wave crest (thick part) maintains rigid support; TPU wave-shaped twisted plates can produce dynamic deformation of 0.5-1mm (adapting to gait).

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
