Man is the only vertebrate with an arch. The presence of the arch is considered both as a feature of “man” and as a hallmark of human evolution. The height of the foot arch is different, so there are normal foot, flat foot and high arch foot. Face these different foot type, whether can choose insole according to uniform standard? First of all, we should understand the foot arch, which is composed of the foot tarsal, metatarsal and ligament and tendon, which can be divided into the medial longitudinal arch, the lateral longitudinal arch and the internal and external direction of the transverse foot arch. The medial longitudinal arch, also known as the elastic foot arch, is a buffer against the shock. The lateral longitudinal arch, mainly related to maintaining the body upright posture, is also known as the support arch. The main function of the foot arch is to disperse the gravity from the ankle joint forward to the metatarsal small head, and back to the calcaneus, to ensure the stability of the plantar support when standing upright. If the arch of the foot is abnormal, it will not only affect the body’s balance and force conduction, but also will easily bring damage and pain to the foot.

Therefore, if you want to wear it comfortably, it is recommended to choose the corresponding arch bearing insole according to your own foot shape. 1. Normal foot. Normal arch presents a natural bow, which can help the human body to absorb the reaction force of the ground, and spread these shocks to the lower limbs to avoid excessive local stress. At the same time, the arch has good elasticity and can help the body to achieve better motor performance, which is often said to jump higher and run faster. For the normal foot arch, it is recommended to choose the foot arch bearing insole with a slight curved foot arch position and a relatively soft material, so as to better fit the foot arch, increase the contact area of the foot sole, and disperse the foot plantar pressure evenly, and be more conducive to the growth of the foot arch. 2. flatfoot. Flat foot shows the collapse or overflattening of the medial longitudinal arch of the foot, and the foot sole is relatively flat. When standing, the foot arch sticks to the ground, usually accompanied by the valgus of the heel. Flat foot will not only affect the appearance of the foot, but also change the pressure distribution of the foot, affect the foot function and lower limb force line, generally manifested as walking easily tired or pain, over time may also lead to foot pain, knee pain, foot injury and poor sports performance. For the arch is low or flat foot tendency, suggest that after understanding the specific arch, choose support strong arch support insoles, give appropriate support strength, which can well maintain the arch radian, effectively improve the plantar force and buffer shock, to improve the symptoms of flat foot discomfort effect. For people with more serious degree of flat foot, it is recommended to customize and wear corrective insoles in hospitals or professional institutions after foot morphological measurement, so as to assist the arch of the foot to give better support to the foot, and avoid the occurrence of lower limb pain and injury. 3. hollow foot. High arch foot refers to the abnormal increase of the foot arch and the shorter length of the foot. Due to the rise of the arch of the foot, the plantar pressure will be concentrated in the front foot and heel, shock absorption force becomes poor, easy to lead to cocoon and pain on the soles of the foot, running and other sports ability is worse, in addition, the increased center of gravity will also be easy to sprain. For people with mild high foot arch foot, they can wear the foot arch bearing cushion to fill the too high foot arch, reduce the pressure of the forepaw and heel, disperse the body gravity and ground rebound force, and make walking more smooth and safe. If the high arch foot condition is more serious, then a pair of professional correction insoles to relieve the symptoms, or to the hospital for surgery.

Different foot type, the choice of insoles is exquisite, so how to judge their own foot type? There are three common methods: 1. Observation method: Take off your shoes and stand on the plane, and observe the height of the arch from the side. 2. Foot printing method: wet your feet, step on the newspaper to leave the foot print, and judge the foot type according to the foot print. 3. Instrument measurement: conduct foot measurement through the instrument. Among them, the observation method and the foot printing method are very simple, and it can be tested at home, but it can only be used as a rough reference, if you want to accurately understand their feet, it is recommended to the relevant institutions to use professional instruments for measurement.
