Seattle Flat Feet, Overpronation & Arch Collapse Treatment Center

Flatfoot Pain in Seattle? Get Relief

Flatfoot, also known as pes planus, is a common condition affecting many individuals in Seattle and beyond. It occurs when the arches of the feet collapse or fail to develop properly, causing the entire sole to make contact with the ground. This condition is caused by pronation, and can affect your gait and cause discomfort or even pain.

Flat feet and arch collapse can contribute to many structural foot problems, including posterior tibial tendon dysfunction (PTTD), bunions, hammertoes, neuromas, midfoot collapse, and midfoot arthritis. Some patients have the opposite problem—high arches (cavus foot)—which can also cause pain, instability, and overload injuries.

At Seattle Foot and Ankle Center, Seattle podiatrist for flatfoot Dr. John Hoy offers comprehensive diagnosis and personalized treatment options — including orthotic management — to help patients regain comfort and mobility.

Foot and Ankle Problems Deserve Specialist Evaluation Early

The foot and ankle are an anatomic region, and podiatry is the specialty dedicated to that region. Musculoskeletal conditions of the foot and ankle have long been part of comprehensive podiatric medicine. Podiatrists diagnose and treat these conditions using both conservative and surgical approaches. A foot and ankle physician can first evaluate the problem, establish the diagnosis, and determine the appropriate course of care. When additional expertise is needed, that care can be coordinated as part of the treatment plan.

When pain persists despite initial treatment, the diagnosis and contributing factors may need to be reassessed.

Flatfoot is often associated with foot and ankle arthritis and treated in a similar fashion. Flatfoot can lead to arthritis and arthritis can cause flatfoot. Flatfoot may be congenital or develop over time as part of adult acquired flatfoot, often due to weakening of the posterior tibial tendon or progressive ligament failure.

What is Flatfoot?

Flatfoot is characterized by the flattening or absence of the arch in the foot. While some people have flexible flatfoot, where the arch appears only when not bearing weight, others have rigid flatfoot, which causes a permanent lack of arch. Flatfoot can develop due to genetics, injury, arthritis, posterior tibial tendon dysfunction (PTTD), or age-related ligament failure.

Common symptoms include:

  • Foot pain or tenderness along the arch or heel
  • Swelling on the inside of the ankle
  • Difficulty standing on tiptoes
  • Fatigue in the feet or legs after prolonged activity

How Does Pronation Relate to Flatfoot?

Pronation refers to the natural inward roll of the foot during walking or running. While pronation is a normal movement, excessive pronation with standing is commonly seen in individuals with flatfoot. This overpronation can cause uneven weight distribution, increasing strain on the foot, ankle, and even the knees and hips.

Over time, untreated overpronation can lead to:

  • Plantar fasciitis
  • Achilles tendonitis
  • Shin splints
  • Knee and lower back pain
  • Bunions
  • Hammertoes
  • Neuromas
  • Midfoot arthritis

Adult Acquired Flatfoot and PTTD

Adult acquired flatfoot is a progressive condition that develops when the posterior tibial tendon weakens or tears, causing the arch to collapse over time. This often leads to pain along the inside of the ankle, progressive flattening, and difficulty walking. Early treatment may help prevent worsening deformity or the need for reconstructive surgery.


Orthotic Management: A Key to Relief

One of the most effective non-surgical treatments for flatfoot and overpronation is orthotic therapy. Custom orthotics are specially designed shoe inserts that provide targeted support to the arch, realign the foot, and reduce excessive pronation.

Benefits of custom orthotics include:

  • Improved foot and ankle alignment
  • Reduced pain and inflammation
  • Enhanced balance and gait efficiency
  • Prevention of further joint and soft tissue damage

Dr. Hoy uses advanced assessment techniques to create orthotics tailored to your unique foot structure and lifestyle needs.


How Flatfoot Can Cause Other Foot Deformities

When the arch collapses, abnormal forces can shift across the foot, increasing pressure on the forefoot and midfoot. Over time, this may contribute to bunions, hammertoes, neuromas, toe deformities, and midfoot arthritis.


Cavus Foot (High Arches)

While flat feet involve arch collapse, cavus foot is the opposite condition—an abnormally high arch. High arches can increase pressure on the heel and forefoot, contributing to stress fractures, ankle instability, tendon injuries, and chronic pain. Proper biomechanical evaluation helps identify the best treatment approach.

Frequently Asked Questions About Flatfoot and Overpronation

What is flatfoot?

Flatfoot, also known as pes planus, occurs when the arch of the foot collapses or does not fully develop. As a result, most or all of the sole of the foot makes contact with the ground when standing. Some people have flexible flatfoot, where the arch appears when sitting or standing on tiptoes, while others have rigid flatfoot with little or no arch at all.

What causes flat feet?

Flatfoot can develop for several reasons, including:
Genetics or inherited foot structure
Weak or stretched tendons in the arch
Injury or trauma to the foot or ankle
Aging and wear on supportive ligaments
Arthritis affecting the foot joints
Some individuals develop flatfoot gradually over time as the supporting structures of the arch weaken.

What symptoms can flat feet cause?

Not everyone with flat feet experiences pain, but symptoms may include:
Pain in the arch or heel
Swelling along the inside of the ankle
Foot fatigue during standing or walking
Difficulty standing on tiptoes
Uneven shoe wear
Pain that radiates to the knees, hips, or lower back
If these symptoms persist, evaluation by a foot and ankle specialist can help determine the cause and appropriate treatment.

What is overpronation?

Pronation refers to the natural inward rolling motion of the foot during walking or running. Overpronation occurs when the foot rolls inward too much, which is commonly seen in individuals with flat feet.
Excessive pronation can place additional strain on the feet, ankles, and legs, potentially leading to other conditions such as:
Plantar fasciitis
Achilles tendonitis
Shin splints
Knee or lower back pain
Proper diagnosis helps identify whether overpronation is contributing to these issues.

How are flat feet diagnosed?

A podiatrist evaluates flatfoot through a physical examination, gait analysis, and assessment of foot alignment. Imaging studies such as X-rays may also be used to evaluate bone structure and determine whether the flatfoot is flexible or rigid.
This comprehensive evaluation helps guide the most effective treatment plan.

Do custom orthotics help flat feet?

Yes. Custom orthotics are one of the most effective non-surgical treatments for flatfoot and overpronation. These specialized shoe inserts support the arch, improve foot alignment, and help distribute pressure more evenly across the foot.
Benefits of custom orthotics may include:
Reduced foot and ankle pain
Improved walking and posture
Less strain on joints and tendons
Prevention of related injuries
Orthotics are designed specifically for each patient’s foot structure and activity level.

Can flat feet lead to other foot problems?

Yes. If left untreated, flatfoot and excessive pronation can contribute to several other conditions, including:
Heel pain and plantar fasciitis
Achilles tendonitis
Shin splints
Knee and hip strain
Chronic foot fatigue
Early treatment can reduce stress on the feet and help prevent these complications.

Do children need treatment for flat feet?

Many children naturally have flat feet during early development. In most cases, arches form as the child grows. However, if a child experiences pain, difficulty walking, or abnormal foot alignment, evaluation by a podiatrist may be recommended.
Early care can help guide proper foot development and prevent long-term problems.

When should I see a podiatrist for flat feet?

You should schedule an evaluation if you experience:
Persistent arch or heel pain
Swelling on the inside of the ankle
Difficulty standing on tiptoes
Foot fatigue during normal activities
Frequent ankle or foot injuries
Early diagnosis and treatment can improve comfort and prevent long-term joint stress.

What treatments are available for flatfoot?

Treatment depends on the severity of the condition and your symptoms. Options may include:
Custom orthotics for arch support
Supportive footwear recommendations
Physical therapy exercises
Activity modifications
In severe cases, surgical consultation
Most patients find relief with conservative treatments such as orthotics and strengthening exercises.
