There is no direct relationship. Congenital flat feet may be caused by genetics or disease. Acquired flat feet are generally postural. During recovery, wear P-type negative heel shoes. The soles are high in front and low in back, which can effectively reduce the pain in the forefoot and foot. Arch Pressure, is an effective forefoot and arch pressure reducing shoe. This change in the force on the sole of the foot can reduce the burden on the ligaments, facilitate walking for patients with flat feet, and also help reduce pain. And it is beneficial and harmless to the human body. Wearing P-shaped, negative-heeled shoes for flat feet is a significant technological advancement. The contents of university textbooks and experimental methods are found in a book with a thickness of two centimeters. Step on the book with the forefoot and the ground with the heel. Shifting the center of gravity backward will reduce the pressure on the forefoot. It should be noted that: Do not wear shoes with heels. Any shoes with heels will increase the pressure on the arch of the foot and aggravate flat feet.
