Flat Feet: Is Low Arch a Concern for Military Service?

Arch problems

Hello, doctor: I would like to ask about a foot health assessment I had a few days ago, where I stood on a device that showed my foot impressions.
The professional determined that my left foot has a low arch (but not classified as flatfoot), while my right foot has a more normal arch.
I would like to know if this means I have flatfoot.
Soon, I will be enlisting in the military, and the physical examination will measure the arch angle; an angle of 168 degrees or less is considered flatfoot.
No one in my family has flatfoot, and I have never experienced the discomfort associated with flatfoot, such as prolonged standing or running, except for one instance of plantar fasciitis.
My left foot's arch appears smaller, but there is still an arch present, unlike flatfoot, which typically has little to no arch.
Therefore, I would like to know if I can be classified as having flatfoot.
Where can I go to have my arch angle checked?

Hello~ Flat feet do not necessarily lead to movement disorders.
The military service physical examination includes X-ray assessments with specific standards; if the angle exceeds 168 degrees, it is classified as alternative service.
In this case, you should inform the examination hospital, and further X-ray evaluation of the arch angle will be conducted.

More Info

Flat feet, or pes planus, is a condition characterized by a low arch or no arch at all in the foot. It can lead to various symptoms, including pain and discomfort in the feet, ankles, knees, and even the lower back. However, not everyone with low arches will experience these issues. In your case, you mentioned that your left foot has a low arch while your right foot has a normal arch. This condition is often referred to as "asymmetrical flatfoot" and may not necessarily qualify as flat feet unless it meets specific criteria.

In the context of military service, the standards for determining whether someone has flat feet can vary. In your case, the military's requirement of measuring the arch angle at 168 degrees or below to classify it as flat feet is a specific criterion. If your left foot's arch angle is above this threshold, it may not be classified as flat feet, even if it is lower than the right foot's arch.
It is important to note that having a low arch does not automatically disqualify you from military service. Many individuals with low arches serve without any issues. The key factors that the military will consider include whether you experience pain or discomfort during physical activities, your overall foot function, and whether you have any related conditions, such as plantar fasciitis, which you mentioned having experienced once.

To assess your arch angle accurately, you should consult a podiatrist or an orthopedic specialist. They can perform a thorough examination, including a physical assessment and possibly imaging studies, to determine the exact nature of your foot structure. They can also provide recommendations for treatment or management if necessary, such as custom orthotics, exercises, or physical therapy to strengthen the foot and improve its function.

In summary, while you have a low arch in one foot, it does not necessarily mean you have flat feet, especially if you do not experience significant symptoms. The military's classification will depend on specific measurements and your overall foot health. Consulting with a specialist will provide you with the most accurate information and guidance regarding your eligibility for military service and any necessary interventions to support your foot health.
