Flat foot occurs when the arch of the foot is lower than usual or collapses, causing the sole of the foot to sit closer to the ground.
Flat foot, sometimes referred to as fallen arches, occurs when the arch on the inside of the foot is reduced or absent. In a typical foot, the arch helps distribute body weight and absorb shock during walking and running. When the arch is lower, the foot may roll inward more than usual, which can change how weight is distributed across the foot and ankle.
Many people with flat feet experience no symptoms at all, and the condition can be a normal variation in foot shape. However, in some cases it can lead to foot fatigue, aching in the arch, heel discomfort, or pain along the ankle. The altered mechanics of the foot can also place additional strain on the ankles, knees, and lower legs.
Assessment by a podiatrist helps identify how the foot is functioning and whether the flat foot is contributing to pain or other issues. Understanding the condition and making appropriate footwear or lifestyle adjustments can help improve comfort and support overall foot health.
