Introduction
Flat feet can affect the body, potentially causing discomfort, limiting prolonged walking, and impairing spinal development. First, individuals with flat feet are prone to conditions such as plantar fasciitis, foot pain, and Achilles tendinitis. Due to insufficient shock absorption in the feet, the knees and hips may also be affected, increasing the risk of knee osteoarthritis and hip inflammation.

Flatfoot (pes planus) refers to the absence or collapse of the normal medial longitudinal arch of the foot. It is important to note that flatfoot is not synonymous with “flatfoot syndrome,” nor does every case of flatfoot require treatment. Flatfoot only constitutes a clinical condition—termed “flatfoot syndrome”—when it is accompanied by symptoms such as pain, in which case intervention may be warranted. In fact, flatfoot is relatively common in the general population, whereas symptomatic flatfoot syndrome is comparatively rare—and when present, it can have significant functional implications.

Does flatfoot have adverse effects?

Yes, flatfoot can adversely affect the body, potentially causing discomfort, limiting walking endurance, and impairing spinal development.

First, individuals with flatfoot are prone to plantar fasciitis, foot pain, and Achilles tendinitis. Due to diminished shock absorption in the foot, excessive stress may be transmitted proximally to the knee and hip joints, increasing the risk of knee osteoarthritis and hip joint inflammation.

Second, flatfoot often impairs walking endurance and exercise tolerance. Prolonged foot fatigue may trigger inflammatory changes in the soft tissues of the foot and cause pain due to abnormal mechanical loading across the joints.

Third, flatfoot may negatively influence spinal development. The lack of adequate arch support leads to navicular bone collapse, ligamentous elongation in the plantar aspect of the foot, and compensatory external rotation of the calcaneus during gait. This altered biomechanics propagates upward, affecting the calcaneus, calf muscles, and knees, ultimately resulting in pelvic tilt, caudal displacement of the sacrum, and even spinal curvature (e.g., scoliosis).

Although flatfoot is highly prevalent, its potential complications are substantial. Many affected individuals experience foot discomfort, and severe or untreated cases may precipitate secondary musculoskeletal disorders. Therefore, timely and appropriate management is essential upon diagnosis to prevent disease progression and avoid increased therapeutic complexity.
