Is the Othotic Insole for Flat Feet Useful?

First of all, we must understand the structure of the foot arch, which is composed of the upper and lower parts. It can be figuratively compared with the structure of the bow and arrow. The upper part is like the back of the bow, and the lower part is like the bowstring. The arch string of the foot arch is the plantar aponeurosis, which is divided into five tendons from the calcaneal tubercle and ends at the flexor tendon sheath and the transverse ligament of the metatarsal head. It is the arch string that maintains the longitudinal arch. The plantar aponeurosis is an important structure to maintain the arch of the foot. If the arch string is relaxed, the arch height will inevitably decrease. The normal arch of the foot is maintained by the bones, ligaments and muscles, known as the three lines of defence.

There are many flat foot arch support pads in the market, flat foot orthodontic shoes, the purpose of which is to play a supporting role on the arch back of the foot arch, but before supporting the arch back, it has played a very negative role on the plantar aponeurosis bowstring. This hard cushion is installed under the arch of the foot. When people stand and walk, the plantar aponeurosis of the arch cushion is constantly squeezed and pulled, which makes the plantar aponeurosis stretched and relaxed. When people wear arch corrective shoes, they feel plantar pain. That is, the plantar aponeurosis is stretched by the rigid arch cushion. If they wear the rigid corrective insole for a long time, the consequences are unimaginable. Damaging the "arch string" is to damage the arch.

The biggest problem in the design of foot arch support pads is that it neglects the function of plantar aponeurosis, which is very important. The foot arch is an integral part of bow back and bow string. It can not be separated from each other. It is against the physiological and mechanical structure of foot. At present, many flat foot orthodontic insoles are not beneficial. And that's the problem. And many shoes with heels will make the body's center of gravity forward and increase the pressure of the arch of the foot. It will also increase the flat foot.
