What is the function and principle of correcting insoles?

The function and principle of corrective insoles can be mainly explained from the following aspects:

effect

Improving foot deformities: The design of corrective insoles aims to correct foot deformities such as flat feet, high arch feet, inversion or eversion. By providing necessary support or increasing pressure in certain areas, pushing the foot towards a normal shape can help gradually correct or alleviate the development of these deformities.

Relieve foot pain: Foot pain is often caused by improper foothold or abnormal foot structure. Corrective insoles can effectively reduce local pain caused by abnormal pressure points, especially when standing or walking for long periods of time, by adjusting the distribution of foot load.

Improving ankle function: insoles help enhance ankle stability and balance by changing the position and angle of ankle movement. This can not only improve the smoothness of the user's gait, but also to some extent prevent falls caused by unstable gait.

Reducing the risk of ankle injuries: By improving the biomechanical structure of the foot and correcting insoles, the risk of impact and sprains on the ankle during high-intensity exercise can be reduced. Reasonable foot support and force distribution are crucial for sports safety.

principle

Biomechanics principle: Corrective insoles are designed based on the biomechanics of the foot, adjusting the support and pressure distribution of the foot and ankle by changing the biomechanical characteristics of the foot. Its design aims to achieve a balance of three-point forces on the transverse arch, medial arch, and lateral arch, thereby improving erroneous forces.

Personalized customization: Many corrective insoles can be customized according to the patient's specific foot shape and needs. For example, using plaster molds to directly fix onto the patient's feet, or heating and molding onto the patient's feet or into plaster molds to provide sufficient space and protection for the feet.

Material characteristics: Orthopedic insoles are often made of materials such as double density EVA (ethylene vinyl acetate), which allows for a wide range of modifications and angles to be created and added to the insole, making it a customizable orthopedic insole. At the same time, these materials also have good support and comfort.

In summary, corrective insoles provide support and cushioning for the foot, adjust the kinematic and mechanical relationships of the foot and its related structures, thereby improving foot function, reducing pain, and preventing injury. However, when using corrective insoles, it should be done under the guidance of a professional doctor to ensure the selection of appropriate insoles and correct usage methods for optimal results.
