Adult Flat Feet Treatment in Livonia & Metro Detroit
Expert Care for Fallen Arches, Painful Flat Feet & Adult Acquired Flatfoot
Flat feet do not always cause problems, but when the arches collapse, the foot becomes painful, or walking starts to feel different, the underlying cause should be evaluated. Adult flat feet can affect the heel, arch, ankle, tendons, knees, and overall walking mechanics.
At Nationwide Foot & Ankle Care, P.C., our podiatrists provide comprehensive adult flat feet treatment in Livonia, Royal Oak, Metro Detroit, and Southeast Michigan, with treatment plans designed around the cause of your arch collapse, symptoms, activity level, and long-term mobility goals.
Comprehensive Care for Fallen Arches
Flat Feet Treatment for Adults in Metro Detroit
Flat feet, commonly called fallen arches, describe feet in which the arch along the inside of the foot is lower than expected or collapses significantly while standing. Some adults have had flexible flat feet their entire lives without pain. Others develop a progressively flatter foot later in life because of tendon dysfunction, arthritis, injury, ligament weakness, or changes in the structure of the foot and ankle.
The appearance of a low arch alone does not necessarily require treatment. What matters most is whether the foot is painful, whether the deformity is changing, whether the ankle is becoming unstable, and whether walking, work, exercise, or everyday activities are becoming more difficult.
At Nationwide Foot & Ankle Care, P.C., we evaluate the entire foot and ankle rather than simply treating the visible arch. This helps us determine whether your symptoms are related to flexible flat feet, overpronation, posterior tibial tendon dysfunction, arthritis, a structural deformity, or another condition.
What Are Flat Feet?
The arch of the foot helps absorb force, distribute pressure, support balance, and create an efficient platform for walking and running. When the arch lowers excessively, the foot may roll inward, the heel may shift outward, and additional stress may be placed on the tendons, ligaments, muscles, and joints supporting the foot and ankle.
Flat feet are generally described as flexible or rigid. Flexible flat feet develop an arch when the foot is not bearing weight but flatten when standing. With rigid flat feet, the arch remains low even when the foot is unloaded and joint motion may be limited.
Adult Acquired Flatfoot & Progressive Collapsing Foot Deformity
One of the most important causes of newly developing flat feet in adults is a condition historically referred to as adult acquired flatfoot deformity or posterior tibial tendon dysfunction. It is also increasingly described as progressive collapsing foot deformity.
The posterior tibial tendon travels along the inside of the ankle and helps support the arch. When the tendon becomes inflamed, stretched, torn, or unable to support the foot effectively, the arch may gradually collapse. As the condition progresses, ligaments and joints may also become involved.
Patients may initially notice pain or swelling along the inside of the ankle. Over time, the heel can drift outward, the arch can become flatter, and the front of the foot may shift outward. Walking longer distances may become increasingly uncomfortable, and standing on the toes can become difficult.
Possible Signs of Progressive Arch Collapse
- A foot that appears flatter than it did previously
- Pain or swelling behind or below the inner ankle bone
- Heel pain or arch pain
- Difficulty standing on one foot or rising onto the toes
- The heel drifting outward
- The forefoot appearing to turn outward
- Ankle pain developing on the outside of the joint
- Increasing difficulty walking or standing for long periods
Progressive changes in foot shape should be evaluated because treatment options may differ significantly depending on the stage of the condition.
What Causes Flat Feet in Adults?
There is no single cause of adult flat feet. Some people inherit a naturally low or flexible arch, while others develop arch collapse later in life. Identifying the cause is essential because a lifelong flexible flat foot is very different from a newly collapsing arch caused by tendon or joint damage.
Inherited Foot Structure
Some adults have had low arches since childhood. Flexible flat feet can run in families and may remain completely painless. Symptoms can sometimes appear later when work demands, sports, weight changes, footwear, injuries, or age place additional stress on the feet.
Posterior Tibial Tendon Dysfunction
Weakness or degeneration of the posterior tibial tendon can reduce support for the arch and contribute to progressive collapse of the foot. This is an important cause of adult acquired flatfoot.
Arthritis
Osteoarthritis, inflammatory arthritis, and arthritis following previous injuries can damage joints that support the arch. As joint alignment and motion change, the foot may become flatter, stiffer, and more painful.
Foot or Ankle Injuries
Fractures, ligament injuries, tendon tears, or trauma affecting the midfoot or ankle may alter alignment and lead to acquired flatfoot or post-traumatic arthritis.
Ligament Weakness or Degeneration
Ligaments help maintain the shape of the foot. When these supporting structures stretch or weaken, the arch may gradually lose stability.
Changes With Age
Tendons, ligaments, cartilage, and muscles can change over time. These changes do not automatically cause flat feet, but they can contribute to symptoms in people who already have vulnerable foot mechanics.
Body Weight and Increased Load
Higher loads on the feet may increase strain on an already weakened arch or painful tendon. Weight is not the only cause of flat feet, but it can influence symptoms and mechanical stress.
Pregnancy-Related Changes
Some people notice changes in foot size or arch height during or after pregnancy. Hormonal changes and increased load may affect the ligaments and structure of the feet.
Common Symptoms of Painful Flat Feet
Many adults with flat feet never experience symptoms. Treatment becomes more important when the arch position is associated with pain, fatigue, instability, tendon irritation, or changes in walking.
Symptoms may include:
- Pain along the arch of the foot
- Heel pain
- Pain or swelling along the inside of the ankle
- Outside ankle pain as the deformity progresses
- Foot fatigue after walking or standing
- Difficulty walking long distances
- Stiffness in the foot or ankle
- Weakness when pushing off during walking
- Difficulty rising onto the toes
- Uneven shoe wear
- Ankle instability
- Pain during running or exercise
- A visible change in the shape of one or both feet
If one foot is becoming noticeably flatter, symptoms are worsening, or your normal activities are becoming more difficult, a podiatric evaluation can help identify the cause.
Where Does Flat-Foot Pain Occur?
Flat feet can affect more than the arch itself. Changes in alignment may influence several structures throughout the foot and ankle.
Arch Pain
Strain through the plantar fascia, muscles, ligaments, and tendons supporting the arch can create aching or fatigue along the bottom or inside of the foot.
Inside Ankle Pain
Pain behind or below the inside ankle bone can be associated with irritation of the posterior tibial tendon, especially when the arch is progressively collapsing.
Outside Ankle Pain
As the heel shifts and the foot becomes more deformed, compression can develop around the outside of the ankle. This may occur in more advanced cases of progressive collapsing foot deformity.
Heel Pain
Flat-foot mechanics may contribute to increased stress around the heel and plantar fascia. Heel pain can have several causes, so a proper diagnosis is important before assuming the arch is responsible.
Knee, Hip, or Leg Discomfort
Changes in foot mechanics can influence movement farther up the leg. Flat feet do not cause every case of knee, hip, or back pain, but they can contribute to abnormal loading or compensation in some patients.
How Adult Flat Feet Are Diagnosed
Successful treatment starts with determining why the foot is flat and whether the condition is stable or progressing. Our podiatrists evaluate foot structure, symptoms, flexibility, tendon function, joint movement, and walking mechanics.
Standing and Non-Weight-Bearing Examination
Comparing the foot while sitting and standing helps determine whether the deformity is flexible or rigid. Your podiatrist may also examine heel position, arch height, forefoot alignment, ankle motion, and areas of tenderness.
Posterior Tibial Tendon Testing
Strength and function of the posterior tibial tendon may be evaluated, particularly when adult acquired flatfoot or progressive collapsing foot deformity is suspected.
Gait Evaluation
Watching you walk helps identify excessive pronation, heel movement, balance concerns, and compensations affecting the ankles or legs.
Diagnostic Imaging
Weight-bearing X-rays may be recommended to assess bone alignment, arthritis, joint position, and the severity of a structural deformity. Additional imaging may be considered when tendon, ligament, cartilage, or other soft-tissue damage is suspected.
Non-Surgical Flat Feet Treatment for Adults
Many painful flat-foot conditions can be managed without surgery, particularly when treatment begins before the deformity becomes rigid or severely arthritic. Treatment is individualized based on the underlying diagnosis and severity of your symptoms.
Custom Orthotics
Custom orthotics for flat feet can support the arch, redistribute pressure, improve foot mechanics, and reduce strain on painful structures. Orthotics are often helpful for flexible flat feet, overpronation, tendon irritation, and activity-related pain.
Supportive Footwear
Shoes with a secure heel counter, appropriate width, cushioning, and adequate stability can improve comfort. Footwear recommendations should match your specific foot structure and activities rather than relying on a single shoe style for every patient.
Bracing
More supportive ankle braces may be recommended when tendon weakness, significant deformity, or ankle instability is present. Bracing can sometimes provide more control than a shoe insert alone.
Temporary Immobilization
A walking boot or other temporary immobilization may be recommended when a tendon is significantly inflamed or painful and needs time to recover.
Physical Therapy
Physical therapy can improve calf flexibility, ankle mobility, tendon strength, balance, and lower-extremity movement. Therapy may be especially helpful when weakness or tightness contributes to symptoms.
Stretching and Strengthening
Targeted exercises may focus on the calf, Achilles tendon, intrinsic foot muscles, posterior tibial tendon, and surrounding stabilizing muscles. Exercise recommendations should be based on the diagnosis because not every painful flat foot responds to the same program.
Activity Modification
Temporarily reducing activities that repeatedly aggravate symptoms can give irritated tissues time to recover. Patients can often maintain fitness through lower-impact alternatives while treatment begins.
Pain and Inflammation Management
Depending on your medical history and diagnosis, your treatment plan may include ice, elevation, or medication recommendations to help control pain and inflammation while the underlying mechanical problem is addressed.
Do Orthotics Help Flat Feet in Adults?
Orthotics are one of the most common treatments for symptomatic flexible flat feet, but their purpose is often misunderstood. Orthotics do not necessarily create a permanently higher arch. Instead, they are designed to improve support, redistribute pressure, control excessive motion, and reduce strain on painful structures.
Custom orthotics may be particularly helpful when flat feet are associated with:
- Arch pain
- Heel pain
- Overpronation
- Foot fatigue
- Posterior tibial tendon irritation
- Abnormal pressure distribution
- Activity-related discomfort
- Associated ankle instability
For more advanced or rigid deformities, an orthotic alone may not provide enough control. A brace or another form of treatment may be recommended instead.
When Is Flat Foot Surgery Considered?
Surgery is not required simply because an adult has flat feet. It is generally considered when significant pain or deformity continues despite appropriate non-surgical care, the arch is progressively collapsing, joints are becoming arthritic, or the condition substantially limits mobility and quality of life.
Surgical planning depends on which bones, joints, tendons, and ligaments are involved. There is no single operation for every case of adult flatfoot.
Flat Foot Reconstruction
Reconstructive surgery may combine several procedures to restore alignment, support the arch, correct tendon dysfunction, and improve stability. The exact combination depends on the stage and flexibility of the deformity.
Tendon Repair or Tendon Transfer
When the posterior tibial tendon is significantly damaged, tendon repair or transfer may be part of reconstruction to improve support and function.
Bone Realignment Procedures
Osteotomies may be used to reposition bones and improve alignment of the heel or forefoot when a flexible deformity requires structural correction.
Ligament Reconstruction
Damaged or stretched ligaments may require reinforcement or reconstruction when they contribute to instability and arch collapse.
Joint Fusion for Advanced Arthritis or Rigid Deformity
When the foot has become rigid or severely arthritic, selected joints may need to be fused to improve stability and reduce pain. Surgical recommendations are based on imaging, symptoms, flexibility, activity goals, and overall health.
Flat Feet and Exercise: Can You Stay Active?
Having flat feet does not automatically mean you need to stop exercising. Many people with flexible flat feet run, walk, lift weights, hike, and participate in sports without significant problems.
The key is whether activity causes symptoms. Repeated pain, swelling, or fatigue after exercise may indicate that your feet are not tolerating the current load well.
For active adults with painful flat feet, treatment may focus on improving footwear, supporting the arches, increasing calf and ankle flexibility, strengthening the muscles that stabilize the feet, and modifying training until irritated tissues recover.
Signs Your Exercise Routine May Be Aggravating Flat Feet
- Arch or ankle pain that increases during running
- Swelling after workouts
- Increasing heel pain
- Pain that lasts into the following day
- A progressive loss of arch height
- Weakness when pushing off
- Increasing difficulty completing normal training
Can Flat Feet Get Worse With Age?
Some adults maintain essentially the same flexible flat-foot structure throughout life. Others experience progressive changes because the tendons, ligaments, or joints supporting the arch become damaged or weakened.
A foot that has recently become flatter deserves more attention than one that has looked the same for decades. New pain, swelling, weakness, or changes in foot shape can indicate an acquired condition rather than a lifelong anatomical variation.
Early evaluation can be particularly valuable when posterior tibial tendon dysfunction or progressive collapsing foot deformity is developing because the available treatment options may change as the deformity becomes more advanced.
When Should You See a Podiatrist for Flat Feet?
You do not need treatment simply because your arches are low. A podiatric evaluation becomes more important when flat feet are painful, worsening, asymmetric, or beginning to interfere with function.
Schedule an evaluation if you have:
- Persistent arch, heel, or ankle pain
- New or increasing flattening of one foot
- Pain or swelling along the posterior tibial tendon
- Difficulty standing on your toes
- Foot fatigue that limits work or daily activity
- Pain while running or exercising
- An ankle that feels unstable
- Progressive changes in foot shape
- Increasing difficulty finding comfortable shoes
- Symptoms that have not improved with basic home care
A comprehensive evaluation can determine whether the issue can be managed with footwear, orthotics, therapy, or bracing, or whether advanced treatment should be considered.

Frequently Asked Questions About Flat Feet in Adults
Do flat feet need treatment in adults?
Not necessarily. Adults with painless flexible flat feet may not require treatment. Treatment is more commonly recommended when flat feet cause pain, fatigue, tendon problems, instability, progressive deformity, or difficulty with normal activities.
Can flat feet develop in adulthood?
Yes. Adults can develop a progressively flatter foot because of posterior tibial tendon dysfunction, ligament weakness, arthritis, injury, or other structural changes. Newly developing flat feet should be evaluated, especially when pain or swelling is present.
Can flat feet be corrected without surgery?
Many symptomatic flat-foot conditions can be treated without surgery using custom orthotics, supportive footwear, bracing, physical therapy, activity modification, stretching, strengthening, and other conservative treatments. The appropriate treatment depends on the cause and severity of the deformity.
Do orthotics work for flat feet?
Orthotics can help many adults with symptomatic flexible flat feet by supporting the foot, redistributing pressure, improving mechanics, and reducing strain on painful tissues. More advanced deformities may require a brace or other treatment.
What is adult acquired flatfoot?
Adult acquired flatfoot describes a progressive loss of arch height that develops during adulthood. Posterior tibial tendon dysfunction is an important contributor, although ligaments and joints may also become involved. The condition may also be described as progressive collapsing foot deformity.
Can flat feet cause ankle pain?
Yes. Some adults with flat feet develop pain along the inside of the ankle because of posterior tibial tendon strain. More advanced deformity can also create discomfort along the outside of the ankle.
Can flat feet cause knee or hip pain?
Flat-foot mechanics may contribute to altered movement and loading through the legs in some people, but knee and hip pain have many possible causes. A comprehensive evaluation can help determine whether foot mechanics are contributing to the symptoms.
Can adults with flat feet run?
Many adults with flexible flat feet can run and exercise without problems. Evaluation is recommended when running causes recurring arch pain, ankle pain, swelling, weakness, or other symptoms that continue despite rest or footwear changes.
When is flat foot surgery necessary?
Surgery may be considered when significant pain, progressive deformity, tendon dysfunction, arthritis, or mobility limitations continue despite appropriate non-surgical treatment. The exact procedure depends on which structures are involved.
Should I see a podiatrist if one foot suddenly becomes flatter?
Yes. A noticeable change in the shape of one foot, especially when accompanied by pain, swelling, weakness, or difficulty walking, should be evaluated to determine whether a tendon injury, progressive collapsing foot deformity, arthritis, or another condition is responsible.
