How Flat Feet Can Alter Your Body Biomechanics

Flat feet, also known as Pes Planus, are a foot condition for those with little or no foot arch when standing upright.

Causes of flat feet

Typically, a human foot consists of 33 joints that hold 26 different bones in place. It also has muscles, tendons, and ligaments to support the bones and the joints.

The foot arches serve as a spring when a person steps and, at the same time, help distribute the person’s body weight across the feet and the legs. The structure of the foot arch determines how the person walks. These arches must be flexible and sturdy enough to ensure the feet can adapt to stress and various surfaces when walking or running.

People with flat feet tend to have more difficulty distributing their weight as their feet may roll to the inner side when standing upright or walking. This condition is known as over pronation and may cause the feet to point outward.

Babies up to six years of age normally have flat feet. As their body develops, so do their foot arches begin to form. While most people develop arches, there are a few people who never develop their foot arches. There are also some cases where the arch falls, leading to acquired flat feet. Some of these conditions include:

  • Obesity - increase in weight puts pressure on feet
  • Aging - people over the age of 40 commonly develop flat feet
  • Hypertension - the reduced blood flow to the feet leads to falling of the arches
  • Injuries to the feet resulting in damage to the foot arches


  • Diabetes
  • Arthritis

Flat feet and Biomechanics

Flat feet affect the overall health. This condition leads to the inability of the feet to properly support the body posture, causing a significant impact on many parts of the body.

Poor Posture 

Flat feet affect the balance resulting in the compensation of other body parts to maintain an upright position. This, in turn, results in elevated and rounded shoulders with the head pushed forward. The hips are also noticeably titled forward with increased curvature of the spine and inward tilting of the knees.

Muscle pain  

Because flat feet affect the body's weight distribution, this causes tension to muscles and ligaments within the legs, the back, and the neck area. This tension results in pain and discomfort around the back, legs, and neck. 

Tired toes and swollen feet 

Because of the disproportionate weight distribution in the feet, the toes try to compensate for the weight resulting in pain and tenderness when walking or standing for long periods.

Balance problems 

People with flat feet struggle with balance compared to those with normal arches. Most of those who suffer from flat feet easily trip over or fall when walking or running.

Knee and Hip Pain

Due to changes in the biomechanics from the flat feet, the knees and hips commonly can experience pain over time.  In fact, the added stress on these areas can contribute to increasing arthritic change.


Flat feet are a complex problem that is not resolved with surgery. Healthcare practitioners offer relief by providing options for the patient to support proper weight distribution in the feet. This is with the help of foot orthotics.

Foot Orthotics are shoe inserts worn to promote proper foot alignment and posture. Some, lower quality orthotics are off-the-shelf cushions that can be used to provide some stress relief in the foot.  However, custom orthotics that are developed after thorough examination and measurements in the feet are available through some healthcare providers.
