Description

Technical Field

[0001] This utility model relates to a thickened badminton functional sports insole, belonging to the technical field of sports insole technology. Background Technology

[0002] It is understood that badminton players often have unique arch shapes and are prone to foot injuries. However, the market lacks functional arch support insoles that comprehensively control the three arches and consider the biomechanics of badminton. The height of the arch is highly correlated with age, frequency of use, weight-bearing load, foot fatigue, and injury. In badminton, the sport requires frequent movement, jumping, and turning, all of which put significant pressure on the arch. Athletes with unique arch shapes, such as flat feet or high arches, are more susceptible to foot injuries because their arches cannot effectively distribute and absorb this pressure.

[0003] However, while many arch support and correction products are available on the market, most only offer additional auxiliary accessories or generic arch support insoles. Although these products provide some arch support, they often fail to fully meet the specific arch support needs of badminton players. Because badminton has unique kinematic characteristics, insoles need to provide arch support while maintaining their original functionality and comfort. Using auxiliary accessories on original badminton insoles may disrupt the overall structure of the insole, affecting its original cushioning and anti-slip functions; while replacing the original insole with a generic one may not perfectly conform to the athlete's foot shape, failing to provide sufficient support and stability. Therefore, these products often cannot truly solve the arch problems encountered by badminton players during the sport.

[0004] In addition, the forefoot thickness of insoles in commercially available badminton shoes is generally 3-4mm. If it's too thin, it will affect wearing comfort, the fit to the arch of the foot, the effectiveness of arch support, as well as the lifespan of the insole and the stability of the shoe. The thickness of the insole is closely related to its lifespan. During prolonged use, the insole is subjected to continuous pressure and friction. If the insole is too thin, its durability will decrease, making it prone to deformation or damage. An insole of appropriate thickness can better resist these pressures and frictions, extending its lifespan. The insole is an important component inside the shoe, and it is closely related to the size and shape of the internal space. If the insole is too thin, the internal space will be too large, which will result in insufficient support and fixation for the foot during exercise, thus affecting the stability of the shoe.

[0005] A normal foot refers to a foot with a normal arch. The arch support area is calculated using the Cavanagh arch parameter formula: AI = B / (A + B + C), where AI represents the arch index, and A, B, and C represent the areas of different regions of the foot.Figure 1 As shown, a foot type database was established by collecting real human foot scan results, and the foot arch was divided into three basic types according to the Cavanagh arch parameter formula: high arch (AI < 0.21), normal arch (0.21 ≤ AI ≤ 0.26), and low arch (AI > 0.26). The three arches are the transverse arch, the medial longitudinal arch, and the lateral longitudinal arch. The three arches make the shape of the entire foot three-dimensional. Together with the plantar fascia, the foot can generate a spring-like effect, which can increase the contact time with the ground to disperse the ground reaction force, thereby reducing the risk of muscle and bone wear / injury, and storing the energy of the reaction force to feed back to the next step.

[0006] The plantar fascia is a fan-shaped connective tissue that supports the arch of the foot, covers the bones from the heel to the toes, and absorbs the impact energy during walking and exercise, making it a very important natural shock absorber for the human body. Plantar fasciitis originates from congenital foot structural factors and acquired usage. During foot degeneration, excessive load or fatigue on the arch causes it to collapse, increasing the pressure and tension on the plantar fascia, leading to small tears. These tears then become inflamed under the repeated stimulation of stretching and tearing. Conversely, strengthening the arch support and compensating for arch collapse can mitigate the impact of exercise on the plantar fascia.

[0007] Studies have found that increased rigidity in the transverse arch leads to increased rigidity in the longitudinal arch, making a significant contribution to overall foot support. The transverse arch (including the plantar fascia) can compensate for longitudinal arch collapse, thereby maintaining the foot arch's shock absorption and rebound functions. Therefore, the focus of the foot arch is no longer just on the medial longitudinal arch; maintaining the curvature of the transverse arch and the allowability of ligament stretching is more helpful in improving arch rigidity and reducing the occurrence of injuries. Utility Model Content

[0008] The technical problem to be solved by this utility model is to overcome the problems existing in the prior art and provide a thickened badminton functional sports insole designed for the special needs of badminton players. It can provide sufficient arch support while ensuring the original functional characteristics and comfort of the insole, thereby truly solving the arch problems encountered by badminton players during sports; at the same time, the thickness of the insole is adjusted to ensure the best wearing effect and sports experience.

[0009] When designing insoles with arch support, the design is generally based on the arch height of a normal foot, with added functional designs to control the transverse arch and the medial and lateral longitudinal arches. Furthermore, considering the functional needs of badminton insoles and common foot problems such as plantar fasciitis, the design helps alleviate exercise pain.

[0010] The technical solution of this utility model to solve its technical problem is as follows:

[0011] A thickened badminton functional sports insole includes an insole body, wherein the insole body has an outwardly protruding arch pad at the arch, the back of the insole body has a high-strength EVA layer corresponding to the arch pad, the back of the insole body has a nylon support piece extending from the midfoot to the heel, and the back of the insole body has a heel cushioning layer.

[0012] This invention relates to an insole designed based on the arch shape of a typical foot, with the addition of a forefoot transverse arch pad. This, combined with a high-strength EVA layer on the back of the insole, helps support the transverse arch while maintaining its arched curvature, preventing the toes from spreading out excessively. This enhances the rigidity of the arch, compensates for existing or sports-related arch collapse, provides better support and control for the arch, and mitigates the effects of high-intensity badminton on plantar fascia degeneration.

[0013] The further improved technical solution of this utility model is as follows:

[0014] Preferably, the insole body consists of a forefoot portion, a midfoot portion, and a heel portion from front to back, with the forefoot portion having a thickness of 7mm, the midfoot portion having a thickness of 10mm, and the heel portion having a thickness of 7mm.

[0015] The thickness of the insole in this invention is increased to 7mm. The increase in insole thickness can enhance the softness, elasticity, cushioning and dispersion of foot pressure of the insole material, make the arch of the foot more obvious, provide a better effect for the above-mentioned arch support design, and also increase the insole's coverage of the heel, thereby improving the overall wearing comfort.

[0016] Preferably, the nylon support piece includes an inner support piece and an outer support piece, the inner support piece and the outer support piece are connected to form an approximately H-shaped structure, the inner support piece is located at the inner longitudinal arch of the back of the insole body, and the outer support piece is located at the outer longitudinal arch of the back of the insole body.

[0017] Preferably, the high-strength EVA layer matches the shape of the open groove on one side of the nylon support sheet, and the heel cushioning layer matches the shape of the open groove on the other side of the nylon support sheet.

[0018] Preferably, the heel cushioning layer is egg-shaped, and the thickness of the egg-shaped cushioning layer is 7-10 mm.

[0019] More preferably, the thickness of the egg-shaped buffer layer is 8 mm.

[0020] This invention features a nylon support plate on the back of the insole, extending from the midfoot to the heel. This not only enhances the support of the inner and outer longitudinal arches but also provides excellent torsional resistance. Extending to the heel, it incorporates an egg-shaped, thickened cushioning design, which improves landing stability and reduces heel discomfort. Helps relieve exercise pain caused by plantar fasciitis .

[0021] Preferably, the forefoot area is provided with a set of breathable and moisture-wicking pores.

[0022] Preferably, the crossbeam pad is provided with multiple breathable and moisture-wicking pores.

[0023] Breathable and moisture-wicking pores allow moisture to escape quickly, keeping your feet dry and comfortable.

[0024] Preferably, the back of the insole body has a flexible texture and a big toe cushioning layer on the forefoot.

[0025] The propulsive motion in badminton primarily relies on the forefoot and thumb for power. This invention increases the thickness of the forefoot and thumb area to enhance the insole's cushioning and durability. Additionally, fine grooves are designed beneath the thickened insole to increase its flexibility, allowing for easy bending of the forefoot to maintain the instantaneous acceleration characteristic of badminton shoes.

[0026] Preferably, a stabilizing block is provided on the back of the insole body on the outer side of the forefoot.

[0027] The stabilizer is made of a high-hardness material on the outer forefoot, which can improve foot stability during lateral movements in badminton.

[0028] Preferably, the front of the insole body has an arc-shaped area extending from the midfoot to the heel and conforming to an ergonomic foot design.

[0029] This product features an ergonomic curved sole design that mimics the curvature of a human foot from midfoot to heel, providing a fully enveloping feel to the foot.

[0030] The advantages of this utility model are as follows:

[0031] (1) The insole of this utility model adds a forefoot transverse arch pad, which is combined with the high-strength EVA material on the back of the insole to effectively support the transverse arch, maintain its curvature structure, prevent the toes from spreading out too much, improve the rigidity of the arch, and compensate for the collapse of the arch; the back of the insole uses a nylon support plate to strengthen the support of the inner and outer longitudinal arches, provide good anti-torsion, and reduce the risk of foot sprains during exercise.

[0032] (2) The egg-shaped thickened cushioning design extending to the heel can enhance landing stability and reduce heel discomfort, which helps to relieve the pain of plantar fasciitis during exercise.

[0033] (3) The increased thickness of the insole makes the insole more soft, elastic, cushioning and dispersing of foot pressure more effective, and makes the arch of the foot more obvious, thus improving the effect of the arch support design.

[0034] In summary, this invention provides insoles that comprehensively consider arch shape, sport characteristics, and foot health, aiming to meet the needs of normal arch support, satisfy the characteristics of badminton, and effectively alleviate foot problems, thereby providing badminton players with comprehensive and professional foot support and protection.
