Description

Shoe Insole {SHOES INSOLE}

The present invention relates to a shoe insole, and more particularly, enhances the shock absorption function of the foot during walking or exercise, and has a pumping function to stimulate and massage acupoints on the soles of the feet to circulate the blood concentrated in the feet to the whole It relates to a shoe insole that can reduce fatigue and stably support the arch of the foot and have body balance.

In general, the foot, which is a part of the human body, is the most used part during walking or exercise, and is one of the very important body parts, such as supporting the body and giving a sense of stability.

As described above, the foot is one of the very important body parts, such as having many uses, and shoes are worn to protect it, and insoles are spread on the bottom surface of the shoes to pursue safety and comfort during walking.

However, the forefoot and heel of the foot are continuously subjected to impact during walking, and when the arch of the foot collapses as a result of standing for a long time or aging, deformation or imbalance occurs in the leg length, hip joint, pelvis, and spine.

As a result, walking becomes uncomfortable, changes occur in bodily functions such as ankles, knees, waists, and shoulders, and fatigue is felt quickly during external activities.

In addition, there are many cases in which sweat is generated in shoes due to a rise in temperature during walking or exercise, and it is not easy to discharge sweat, which causes inconvenience and deterioration in comfort on the foot side, and there is a problem in that fatigue is doubled.

Therefore, in order to develop a shoe or insole that can improve or solve the above-mentioned problems, the industry has been conducting a lot of research and development and making efforts, and various technologies have been proposed and disclosed.

Meanwhile, in the prior art, Korean Patent Publication No. 10-2021-0001322 and Korean Utility Model Registration No. 20-0335961 may be referred to.
