Normal foot and ankle biomechanics describe how the bones, joints, and ligaments work together during movement. Healthy biomechanics allow the foot to absorb impact, adapt to different surfaces, and provide stability when needed. During weight-bearing activities, the feet support the body while distributing pressure across the heel, midfoot, and forefoot. Proper alignment and controlled movement help reduce unnecessary stress on the lower extremities and support efficient walking, standing, and exercise.

Walking follows a coordinated sequence that begins when the heel contacts the ground and continues as the body moves forward over the foot. The ankle and foot gradually adjust to absorb impact before becoming more stable for push-off. Muscles and tendons provide control throughout this process. If alignment, flexibility, or joint motion is altered, certain areas may experience increased pressure. These changes can contribute to discomfort, overuse injuries, or changes in walking patterns.

Running places greater demands on foot and ankle biomechanics because the body experiences increased impact and faster movement. The foot must absorb force and then become stable enough to help propel the body forward. Risk factors for abnormal biomechanics include previous injuries, muscle weakness, and limited flexibility. Structural differences, improper footwear, and sudden increases in activity may also be factors. Symptoms of a biomechanical problem may include persistent foot or ankle pain, uneven shoe wear, or discomfort during weight-bearing activities.

A podiatrist can evaluate biomechanics by observing walking and running patterns and examining foot alignment, joint movement, and weight distribution. The foot doctor may also recommend supportive shoes, orthotics, or activity changes when appropriate. Follow-up visits can help determine whether treatment is improving movement and reducing stress. Understanding foot mechanics can support injury prevention and better mobility. If you have foot or ankle pain and want to understand your foot biomechanics, it is suggested that you consult a podiatrist for an accurate diagnosis and appropriate treatment.

Biomechanics in Podiatry

Podiatric biomechanics is a particular sector of specialty podiatry with licensed practitioners who are trained to diagnose and treat conditions affecting the foot, ankle and lower leg. Biomechanics deals with the forces that act against the body, causing an interference with the biological structures. It focuses on the movement of the ankle, the foot and the forces that interact with them.

A History of Biomechanics

• Biomechanics dates back to the BC era in Egypt where evidence of professional foot care has been recorded.
• In 1974, biomechanics gained a higher profile from the studies of Merton Root, who claimed that by changing or controlling the forces between the ankle and the foot, corrections or conditions could be implemented to gain strength and coordination in the area.

Modern technological improvements are based on past theories and therapeutic processes that provide a better understanding of podiatric concepts for biomechanics. Computers can provide accurate information about the forces and patterns of the feet and lower legs.

Understanding biomechanics of the feet can help improve and eliminate pain, stopping further stress to the foot.
