Description

Arch insole

The present invention relates to the field of insoles, particularly arch insoles.

In daily life, people walk in shoes for a long time. Without good support, the internal joints absorb the pressure generated by the walking process, and bear great ground reaction force. The slight ones produce foot pain or tension. Moreover, the shoes make people's movements of the internal joints restricted during walking, unable to maintain good mobility and elasticity, causing pressure to accumulate in the lower limb joints outside the joints of the feet, and more likely to cause ankles and knees in severe cases. Joints, hips and even spine-related diseases.

A variety of functional insoles are currently available on the market. Generally, functional insoles are usually provided with a cushion made of elastic sponge at the corresponding arch to absorb shock or pressure generated during the user's travel. The evaluation of such products in the initial stage of use is generally good, but after a long period of use, the elastic sponge is deformed due to the loss of resilience, and it is unable to effectively support and disperse the pressure generated when the user walks. In addition, prolonging the user's foot on an unevenly deformed insole may also accelerate the damage caused by degeneration of the user's foot or even the knee joint or hip joint.

In view of this, there is a need in the art for an improved arch insole that provides individual foot support and flexibility to improve prior art deficiencies.
