The arched portion of the foot located between the toes and the ankle is a crucial anatomical structure. This upward curve, formed by the tarsal and metatarsal bones, along with ligaments and tendons, provides both flexibility and support during weight-bearing activities like walking and running. A healthy arch distributes body weight evenly across the foot, mitigating pressure on the heel and the ball of the foot.
Proper arch structure is essential for biomechanical efficiency and injury prevention. A well-supported arch acts as a shock absorber, reducing impact stress on the lower extremities and spine. Conversely, deviations from the normal arch height, such as excessively high or flat arches, can lead to conditions like plantar fasciitis, metatarsalgia, and ankle instability. Maintaining arch integrity contributes significantly to overall musculoskeletal health and athletic performance.
