The sole of the human foot must be bent, because the muscles in combination with the bone structure are the spring of the moving body. So it is the first way to absorb body impacts from walking and running. In flat feet, this function exists to a limited extent or not at all, and uneven muscle tension also causes many complaints. What causes pain in uneven flat feet and why are corrective measures necessary for good posture?

How much should the arch be?
As soon as the child grows up, the shape of the sole must be good to ensure optimal further body development. Problems can arise with the curvature of the foot, causing the growing body to not grow properly. It can result in crooked growth, overloaded joints and pain. If the foot has grown, there should be a standard convexity of approximately 1.3 centimeters in order to be able to perform the walking movement smoothly. If the curvature is more, it is a hollow foot and if it is much less, it is a flat foot. What could it lead to?
What causes uneven flat feet?
Every foot is not the same in terms of shape, muscle formation and bone size. Because different muscle tensions may apply, a bulge may be larger or smaller than normal. It can happen that the muscles are so tense that the bulge under the foot has completely disappeared. As a result, walking will be less smooth and may possibly cause a clapping movement. Because the walking movement is not smooth, it has consequences for the other joints.
Uneven arch two soles
There is often flat feet in both legs. The tension in the muscles can differ per foot, causing the bulging of the soles to differ. Without additional support under the sole, an unevenness occurs, causing the body to move out of its normal position. It means that the hips are slightly crooked and the spine is also out of alignment. As the child grows up, this growth must be compensated so that the body returns to its normal upright position.
Necessity to wear insoles when growing up
There is still a debate going on as to whether wearing insoles is necessary. On the one hand, it would ensure that the sole grows in the correct position, while the rest of the body is also in the correct position. On the other hand, it is assumed that the sole of the foot derives dependence from the insole. That in itself is true, but the supported sole also influences the correct position of the rest of the body. It deserves special attention if there is uneven growth in the arch of the foot, so that an incorrect position can be avoided. To prevent nerve compression and a far-reaching incorrect growth position, wearing insoles is recommended despite the dependence. Once the child turns twelve or thirteen, the arch of the foot has grown and it can be determined to what extent additional insoles are needed.
Difference between flexible and stiff flat feet
If the muscles are so tense that the bottom is practically straight, it may be a stiff flat foot. If you stand on your toes, the bulge may not return. It is the most advanced stage of flatfoot, in which muscle stiffness does not show deformability of the bottom. This means that the foot no longer has a cushioning effect, making walking more jarring. To compensate for this, you need to walk in an adapted manner, so that the movement runs optimally.
A distinction is made between complaints with uniform soles and with uneven growth. Consider the following complications.
With an equally reduced arch on the left and right, the body is in a normal position, but the shock absorption effect is less or non-existent. The walking movement is also completed less smoothly. It ensures that muscles are used differently and joints are loaded in a less normal way. It can lead to premature bone wear. With an adapted walking method there will be no dramatic consequences.
With an uneven arch (without the use of insoles), the body will become crooked. The hips are in the wrong position and so is the back. It can lead to lower back pain, hernia, stiff neck muscles, chronic muscle tension headaches, sciatica, leg pain, and so on. Many of these complaints are related to the position of the body. The greater the difference in arch, the more serious the complaints can be.
How to intervene?
As the child grows up, attention should be paid to the position of the hips at an early stage. If a difference is noticeable, one leg may be slightly longer or there may be an uneven arch. To ensure normal growth, the growing child must wear insoles. This allows growth to be reasonably corrected so that the hips and spine are perpendicular. If you are older and have complaints, attention should also be paid to your posture. A condition such as sciatica can cause severe pain in the legs due to pinched nerves. Aids and walking techniques can ensure that the influence of complaints is minimal, so that you can walk in a reasonably normal manner. Ask a (manual) therapist what you can best do to reduce the complaints.
