Description
Technical Field
The invention relates to an insole, in particular to a pressure-relieving and fatigue-resisting walking insole.
Background
Modern people often have too much teaching in wearing shoes when walking, but neglect the important function of the insoles. The insoles are common daily articles, and can be divided into health-care insoles, functional insoles and conventional insoles according to the function. The structure of the traditional insole is formed by sewing multiple layers of cloth or pressing multiple layers of leather, has certain softness and buffering and damping effects, and basically meets the requirement of ordinary walking shoes.
However, when walking, the excessive walking can cause hyperosteogeny, and some people who may feel tired and feel blisters can feel blisters when walking for a long time. Many patients who see a doctor due to heel pain mainly show pain below the heel with slight swelling, and the pain is aggravated after walking on the ground; some people get up in the morning or start to walk after rest with more obvious pain, but the pain is relieved after slight activities, but the pain is aggravated when walking more.
When a person normally walks, each foot needs to go through the processes of stepping (landing the heel), rolling (the gravity center moves forwards in a transition mode, one leg is in a swing stage) and pedaling (the metatarsophalangeal joint bends the toes and pedals the toes off the ground). The foot arch can lead gravity to be transmitted and dispersed from the ankle joint to the metatarsal bone capitis forwards and backwards to the calcaneus through the talus (bones of joints between the ankle and the crus bones which bear the weight of a human body), and the impact of the ground on the body is buffered, so that the brain and internal organs are protected from concussion. The feet of the person are in arch shape like an arch bridge, which is a guarantee for the stability of the body. The arch is an integral system formed by fusing joints, ligaments and muscles, and the bending and elasticity of the arch can adapt to uneven ground to play a role in bearing and absorbing shock. Our foot bears the body weight of the whole body, and any change in the physiological curvature of the arch will seriously affect the weight-bearing function of the arch, as well as walking, running and maintaining body posture. The contact area between the outer longitudinal arch and the ground is larger when the user walks, so that the stability of the human body is improved when the user stands and moves, the curvature of the inner longitudinal arch is larger, so that the foot is more elastic, and part of impact can be counteracted during the movement.
Changes in arch morphology can affect its physiological function and, in severe cases, can cause health problems. For example, when wearing high-heeled shoes, the foot sole bends, the arch radian is reduced, the ankle joint is loosened and unstable, the lateral movement can be performed, and the probability of sprain is greatly improved.
When walking, the traditional insole has the following defects: firstly, the traditional insole has poor shock absorption and foot protection effects, the impact force on the half sole and the bottom of the heel of the foot is large during exercise, the traditional insole has poor elasticity, is difficult to absorb the impact force on the foot bones during walking and exercise, is difficult to protect the foot bones, ankles and knee joints, and is not suitable for long-term walking; secondly, the traditional insole has poor air permeability, is easy to breed bacteria and fungi, and is easy to cause foot problems such as dermatophytosis and the like; thirdly, the arch of the traditional insole is not bent, the insole is not easy to bend, the arch of the foot cannot be protected, and the flat foot cannot be improved; fourthly, the traditional deodorant insole contains components which are irritant to skin, so that the skin of the sole of a foot can be dry after being worn for a long time, and severe people can have chaps and cannot achieve the aim of deodorization; fifthly, the traditional insoles are too thick, too heavy, too light and too hard to meet the physiological requirements of human bodies, and have no special protection effect on heels; sixthly, the traditional insole can not massage the soles of the feet, and people feel uncomfortable to walk and have enhanced fatigue feeling after wearing the insole for a long time.
