If it is not congenital and there is no trauma, it is possible to recover from flat feet. You can wear a pair of patented negative-heeled shoes with soles that are high in the front and low in the back to reduce the pressure on the arch and help recovery. This patented negative-heeled shoe can be purchased in some tertiary hospitals and is an effective arch-decompression shoe. Directly reducing the burden on the arch of the foot is beneficial to the walking of patients with flat feet, and is also beneficial to reducing pain, and is beneficial to the human body.
Patients with flat feet are better able to walk in flat shoes than in shoes with heels, and their symptoms will be less severe. Symptoms can be further alleviated by wearing flat shoes and walking on your heels. Negative heel shoes are high in front and low in back, which can reduce the pressure on the arch of the foot to a greater extent. You can try it out by stepping on a book about 18 mm thick with your front feet barefoot or wearing flat shoes to see if the symptoms of flat feet are relieved.
If you have flat feet, you should avoid standing or walking for too long, especially walking with too much weight. After fatigue, you should rest in time and pay attention to recovery. Pay special attention not to wear any shoes with heels. Heels of any height will increase the pressure on the arch of the foot - high heels are harmful, and mid-heeled shoes are moderately harmful, but they are by no means beneficial or harmless! There is a popular science article "The Rights and Wrongs of Shoes and Health" which makes it very clear.
