Flat Feet (Fallen Arches): What Patients Should Know

Flat feet, also known as fallen arches, are a common foot condition seen by podiatrists across all age groups. While some people with flat feet experience no discomfort, others may notice pain, fatigue, or changes in the way they walk. Understanding flat feet — and knowing when to seek professional evaluation — can play an important role in maintaining long-term foot comfort and mobility.

At Laguna Woods Podiatry Group, Dr. Neda Arjomandi, DPM, Board-Certified Podiatrist, regularly evaluates and treats patients with flat feet using individualized, evidence-based care.

What Are Flat Feet?

Flat feet occur when the arches of the feet are lower than normal or absent, causing the entire sole of the foot to make contact with the ground when standing. Flat feet may affect one or both feet and can be present from childhood or develop later in adulthood.

There are two general types:

• Flexible flat feet – the arch appears when sitting or on tiptoes but flattens when standing

• Rigid flat feet – the arch remains absent both sitting and standing

Common Causes of Flat Feet

Flat feet can develop for several reasons, including:

• Genetics or inherited foot structure

• Weak or overstretched tendons, particularly the posterior tibial tendon

• Aging-related changes in ligaments and joints

• Prior foot or ankle injuries

• Arthritis or inflammatory conditions

• Pregnancy or weight changes that place additional stress on the feet

In adults, a progressive flattening of the arch may indicate tendon dysfunction and should be evaluated by a podiatrist.

Symptoms Patients May Notice

Not all flat feet cause symptoms, but when they do, patients commonly report:

• Foot or arch pain, especially after standing or walking

• Heel or ankle discomfort

• Fatigue in the feet or legs

• Pain along the inside of the ankle

• Changes in walking pattern or balance

• Knee, hip, or lower back discomfort related to altered biomechanics

Symptoms may worsen with prolonged activity or improper footwear.

When to Seek Podiatric Evaluation

It’s important to schedule a podiatric evaluation if you experience:

• Persistent foot or ankle pain

• Progressive flattening of the arch

• Difficulty walking or standing for long periods

• Uneven shoe wear

• Swelling along the inside of the ankle

Early assessment may help identify contributing factors and guide appropriate treatment options.

How Flat Feet Are Evaluated

During an office visit, a podiatrist may assess:

• Foot structure and alignment

• Gait and walking mechanics

• Muscle strength and tendon function

• Areas of tenderness or instability

Imaging studies may be recommended when necessary to better understand bone or tendon involvement.

Treatment Options for Flat Feet

Treatment for flat feet depends on symptoms, activity level, and overall foot health. Options may include:

• Supportive footwear designed to improve stability

• Custom orthotics to support the arch and improve alignment

• Activity modification when appropriate

• Stretching and strengthening exercises

• Bracing in certain cases

• Advanced care options for progressive or painful conditions

A personalized approach is essential, as not every patient with flat feet requires the same treatment.

Everyday Tips for Supporting Flat Feet

Patients with flat feet may benefit from:

• Wearing supportive shoes with firm heel counters

• Avoiding worn-out or unsupportive footwear

• Replacing athletic shoes regularly

• Gradually increasing activity levels

• Paying attention to new or worsening symptoms
