Flat feet, a condition where the arch of the foot flattens, are often considered normal and usually don't cause concern unless they become painful. This is a common belief among medical practitioners.

​

While flat feet are not as harmful as serious diseases like cancer or diabetes, they can compromise the coordination of different body parts during daily activities and sports.

How Flat Feet Affect Movement

​

In typical walking, the ankle, knee, and hip flex and extend smoothly. These movements are deemed normal because they involve a wide range of motion controlled by larger muscle groups, which can work for extended periods.

However, for those with flat feet, this natural flexion and extension are significantly reduced. Instead, the legs' joints resort to rotational movements, which have a limited range of motion.

​

This restriction impacts walking speed and agility. Moreover, the repetitive rotational forces exert constant strain on the ligaments surrounding the ankle and knee joints, causing them to become lax and loose.

​

This leads to permanent joint instability, making the ankle and knee more prone to injuries. The hip is less affected due to the greater number of muscles controlling its rotation.

​

Consequences of Joint Instability

​

When the ankle and knee joints become unstable, they are more susceptible to injury. The muscles around these joints struggle to function properly because the ligaments, acting as hinges in the leverage system, are loose. This is similar to how a poorly hinged door is harder to control.

​

Anyone who has experienced an ankle sprain or knee injury knows how long it takes for the pain to heal and the difficulty in regaining confidence to use the affected joint. Flat feet increase the likelihood of such injuries, leading to a cycle of pain and hesitation in physical activity.

Living with Flat Feet

​

While flat feet don't pose the same threat as life-threatening illnesses, they can significantly impact quality of life. They make us physically vulnerable, preventing us from engaging fully in activities like sports, running with children, or playing basketball with friends. The fear of injury can overshadow the joy of these experiences.

​

In summary, while flat feet may seem minor compared to severe health issues, they can lead to significant physical challenges and limitations. Understanding and addressing these issues can help those affected live more active and fulfilling lives.
