Flat feet, we must first understand the structure of the arch, which is composed of upper and lower parts, and can be vividly compared to the structure of bows and arrows. The upper part is like the back of a bow, and the lower part is like a bowstring. The bowstring of the arch of the foot is plantar aponeurosis, which starts from calcaneal tubercle, divides into five tendons forward, and ends at flexor tendon sheath and transverse metatarsal ligament, and is the bowstring that maintains the longitudinal arch of the foot. Plantar aponeurosis is an important structure to maintain the arch of the foot. If you relax this arch string, the height of the arch will inevitably decrease. The normal arch of the foot is maintained by bones, ligaments and muscles, which is commonly known as the three lines of defense. There are many flat foot pads and flat foot corrective shoes on the market, which are aimed at supporting the arch back of the arch, but before supporting the arch back, they have already played a very unfavorable role in plantar aponeurosis. This hard pad is installed under the arch of the foot. When people stand and walk, the plantar aponeurosis is constantly squeezed and pulled, so that the plantar aponeurosis is stretched and relaxed. When people put on shoes to correct their arches, they will feel pain in the soles of their feet, that is, the hard arch pad is stretching the plantar aponeurosis. If people wear hard orthopedic insoles for a long time, the consequences will be unimaginable. The injury of "bowstring" is the injury of arch. The biggest problem in the design of arch pad is that it ignores the function of plantar aponeurosis as a "bowstring", which is very important. The arch of the foot is a whole composed of "arch back" and "bow string", so it is against the physiological and mechanical structure of the foot to emphasize the support of "arch back" mechanically. At present, many insoles for correcting flat feet are harmful and useless, and this is the problem. Moreover, many shoes have heels, which will move the center of gravity forward, increase the pressure on the arch and aggravate flat feet.
Flat feet are mostly caused by long-term pressure on the forefoot arch, and reducing the pressure on the forefoot arch is the fundamental correction. Therefore, flat shoes must be more beneficial than shoes with heels, and patients generally report that wearing flat shoes has stronger walking ability and lighter symptoms than wearing shoes with heels. Patients with flatfoot often use heel stress to reduce arch pressure and relieve symptoms. You can do an experiment, barefoot or wearing flat shoes, stepping on a book with a thickness of about 18 mm with your front foot and stepping on the ground with your back foot to see if the symptoms of flat feet are relieved.
If there is any relief, you can use a pair of patent heel shoes with high front and low back. Repeated customers buy more. The sole is high in the front and low in the back, effectively reducing the pressure on the forefoot and arch. It is an effective forefoot and arch decompression shoe. This change of plantar stress can reduce the burden of ligaments, which is beneficial to the walking and pain relief of patients with flat feet. But also beneficial and harmless to human body. Patent heel shoes can be bought in some top three hospitals.
Note: Don't wear shoes with heels at ordinary times. Any shoes with heels will increase arch pressure and aggravate flat feet.
