Neither flat nor curved feet are inherently "better." The optimal foot structure depends on individual factors and how well the foot functions. While high arches and flat feet both present potential problems, neither is universally superior.
Understanding Foot Arches
The arch of the foot acts as a shock absorber and helps with efficient movement. A healthy arch provides proper weight distribution and support during activities.
-
High Arches (Supination): High arches can lead to reduced shock absorption, potentially causing pain in the feet, ankles, knees, and hips. The rigid nature of a high arch means it doesn't flatten during gait, unlike a normal functioning foot. (Source 1) (Source 7) High-arched feet tend to turn outwards. (Source 2)
-
Flat Feet (Pronation): Flat feet lack sufficient arch support, leading to overpronation (rolling inwards). This can also cause pain and discomfort in various parts of the body due to improper weight distribution. However, flat feet offer advantages in some contexts; for example, they provide greater stability for activities like weightlifting and certain combat sports. (Source 3) (Source 1) Flat feet often turn inwards. (Source 2)
The Importance of Function over Form
The key is how well the foot functions, not simply its shape. Both flat feet and high arches can cause problems if they lead to poor weight distribution, gait issues, and pain. (Source 8) The arch's role as a shock absorber is vital; the lack of this function in high arches and its overcompensation in flat feet are both sources of potential problems. (Source 5) (Source 6)
Genetic predispositions influence foot structure. (Source 10) Ultimately, a podiatrist can assess individual foot function and suggest appropriate interventions, such as orthotics or exercises.
