Flat feet, or pes planus, is a condition where the arch of the foot is completely flattened or less pronounced than normal. This common orthopedic condition affects both children and adults. The foot arch plays a critical role in distributing body weight evenly during walking, running, and standing, absorbing shock, and reducing stress on joints. In flat feet, however, the arch is absent, causing the entire sole to touch the ground. This condition can be congenital or develop later due to factors such as age, injuries, obesity, improper footwear, or various health issues.
In this article, we will explore flat feet symptoms, treatment options, severity levels, potential complications, diagnostic tests, exercises, and more in detail. We will also provide practical information on how flat feet affect daily life, treatment methods, and preventive measures to help you manage the condition effectively. The characteristics of individuals with flat feet and the condition’s impact across different age groups will also be thoroughly examined.
What is Flat Feet?
Flat feet is a condition where the inner arch of the foot (longitudinal arch) is either absent or minimally pronounced. In a typical foot, the arch supports body weight, provides balance during movement, and absorbs impact while walking. In flat feet, however, the arch flattens, and the sole makes full contact with the ground. While this condition may be asymptomatic and not affect daily life for some, it can cause significant issues for others, including pain, fatigue, restricted movement, and joint problems.
Characteristics of individuals with flat feet often include a predisposition to pain, rapid fatigue during walking or standing, balance issues, and joint discomfort. Flat feet can result from genetic factors, improper footwear, obesity, tendon weakness, or various health conditions. For example, wearing unsupportive shoes for extended periods or excessive weight-bearing due to obesity can weaken the arch structure over time.
Types of Flat Feet
Flat feet are generally categorized into two main types: flexible flat feet and rigid flat feet. These types differ in causes, symptoms, and treatment approaches.
Flexible Flat Feet
Flexible flat feet occur when the arch is visible when the foot is not bearing weight but flattens when weight is applied. This type is more common in children and is often painless. In most children, the arch develops naturally during growth (typically between ages 5-10), and the condition resolves on its own. However, flexible flat feet can persist into adulthood, sometimes causing pain, fatigue, or balance issues. For instance, an adult may experience foot pain after standing for long periods or engaging in intense physical activities. Supportive shoes and orthotic insoles are typically effective solutions in such cases.
Rigid Flat Feet
Rigid flat feet are characterized by a consistently flat arch, regardless of weight-bearing, with no flexibility. This type is often linked to congenital bone abnormalities or structural issues. Rigid flat feet can cause pain, restricted movement, and joint problems. For example, a patient may experience heel or knee pain during walking. Treatment is more complex than for flexible flat feet and may require surgical intervention in some cases. Surgery may involve tendon repair or bone fusion.
Symptoms of Flat Feet
Flat feet symptoms vary from person to person. While some individuals are unaware of the condition and experience no discomfort, others face significant health issues. Common symptoms include:
- Pain in the sole or arch of the foot
- Fatigue after prolonged standing or walking
- Pain in the heel, ankle, knee, hip, or lower back
- Swelling or tenderness in the feet
- Balance issues during walking or running
- Rapid wear on the inner side of shoes
- Toe deformities (e.g., bunions or hammertoes)
These symptoms often worsen with prolonged standing or wearing inappropriate shoes. For example, an office worker walking on hard surfaces in flat shoes may experience foot and back pain by the end of the day.
Flat Feet in Adults
In adults, flat feet often result from posterior tibial tendon weakness, obesity, diabetes, rheumatoid arthritis, or foot injuries. The complications of flat feet are more pronounced in adults. For instance, prolonged standing or heavy physical activities can exacerbate pain and limit daily activities. Adult flat feet are typically managed with physical therapy, orthotic insoles, or surgical intervention. Controlling risk factors like obesity also plays a significant role in alleviating symptoms.
Flat Feet in Children
Flat feet in children are often part of normal development. Babies and young children are born with flat feet as the arch has not yet fully formed. By ages 5-6, the arch typically develops. However, if the condition persists or the child exhibits symptoms like pain, difficulty walking, balance issues, or uneven shoe wear, an orthopedic specialist should be consulted. Pediatric flat feet are usually flexible and often resolve spontaneously. For example, a child who frequently falls while running or has rapidly worn inner shoe soles may have flat feet.
What Causes Flat Feet?
The causes of flat feet vary, involving both genetic and environmental factors. Key causes include:
- Genetic Factors: A family history of flat feet increases the likelihood of the condition. For example, if a parent has flat feet, the child is at higher risk.
- Tendon Weakness: Weakness or damage to the posterior tibial tendon can cause the arch to collapse.
- Injuries: Ankle sprains, fractures, or tendon injuries can lead to flat feet.
- Obesity: Excess weight places excessive stress on the arch, causing it to flatten. For instance, an individual with 20 kg of excess weight may experience arch collapse due to increased load.
- Medical Conditions: Diabetes, rheumatoid arthritis, cerebral palsy, or muscular diseases increase flat feet risk.
- Improper Footwear: Shoes lacking support (e.g., flat sandals or high heels) contribute to arch flattening.
- Aging: Weakening tendons and ligaments with age can lead to flat feet.
What Are the Degrees of Flat Feet?
Flat feet are classified into three main severity levels, which are critical for diagnosis and treatment planning:
- Mild Flat Feet: The arch is slightly flattened and typically asymptomatic. Supportive shoes and insoles can easily manage it. For example, a patient may feel mild fatigue after prolonged standing.
- Moderate Flat Feet: The arch is more noticeably flattened, with symptoms like pain, fatigue, and restricted movement. Physical therapy and orthotic insoles are often recommended. Patients may experience balance issues during running or walking.
- Severe Flat Feet: The arch is completely absent, leading to significant pain, joint issues, and walking difficulties. Surgery may be required. For instance, a patient may experience severe pain during daily walks.
What Are the Complications of Flat Feet?
Untreated flat feet can lead to serious health issues, including:
- Chronic Pain: Persistent pain in the feet, knees, hips, or lower back. For example, a patient may feel heel pain during morning steps.
- Tendon Inflammation: Posterior tibial tendinitis or other tendon issues.
- Plantar Fasciitis: A common cause of heel pain associated with flat feet.
- Ankle Sprains: Increased risk due to balance loss.
- Joint Wear: Uneven weight distribution can lead to osteoarthritis.
- Gait Abnormalities: Prolonged flat feet may alter walking patterns, causing limping.
- Foot Deformities: Bunions, hammertoes, or cavus foot.
These complications, if untreated, can significantly reduce quality of life.
How is Flat Feet Diagnosed?
A flat feet test is one of the simplest ways to diagnose the condition. The most common method is the “wet foot test.” Wet your feet, then walk on a dry surface. If your footprint shows no arch (a completely filled sole), flat feet are likely. In a normal footprint, the arch leaves a gap, while a flat foot print appears fully filled. An orthopedic specialist can confirm the diagnosis through physical examination, X-rays, MRI, or gait analysis. Symptoms like rapid inner shoe wear, pain during walking, or balance issues while standing also indicate flat feet.
Flat Feet Treatment
Flat feet treatment is tailored to the condition’s severity, symptoms, and the patient’s lifestyle. Key treatment methods include:
- Orthotic Insoles: Custom insoles support the arch, reduce pain, and improve movement. For example, 3D-scanned insoles can be personalized.
- Proper Footwear: Wide-toed, supportive, arch-friendly shoes are recommended. Athletic or orthopedic shoes are ideal.
- Physical Therapy: Exercises strengthening foot and leg muscles support the arch. Physiotherapist-guided sessions provide long-term relief.
- Medication: Nonsteroidal anti-inflammatory drugs (NSAIDs) can manage pain and inflammation.
- Surgery: In severe cases, procedures like tendon repair, bone fusion, or arch reconstruction may be necessary. For example, a patient with significant tendon damage may require surgery.
- Weight Control: Obesity exacerbates flat feet. Weight loss reduces stress on the feet.

What Happens if Flat Feet Are Untreated?
Untreated flat feet can lead to serious complications, including chronic pain, joint damage, tendon inflammation, and gait abnormalities. Additionally, flat feet place excess stress on knees, hips, and the lower back, potentially causing osteoarthritis over time. For example, an untreated patient may develop cartilage wear in the knee joint years later. Early intervention significantly reduces these risks and preserves quality of life.
What Should People with Flat Feet Pay Attention To?
Individuals with flat feet, prone to pain and restricted movement, should:
- Wear supportive, arch-friendly shoes, such as orthopedic athletic shoes.
- Avoid excess weight to reduce stress on the feet.
- Limit prolonged standing or walking on hard surfaces.
- Perform regular exercises to strengthen foot and leg muscles.
- Schedule regular check-ups with an orthopedic specialist.
- Avoid walking barefoot on hard surfaces.
Flat Feet Exercises
Flat feet exercises strengthen foot muscles, support the arch, and reduce pain. Examples include:
- Heel Raises: Stand and slowly lift your heels, hold for 5 seconds, then lower (15 repetitions, 3 sets).
- Toe Curling: Place a towel on the floor and pull it toward you with your toes (2 minutes).
- Arch Massage: Roll a tennis ball or cylinder under your foot (5 minutes).
- Toe Spreading: Open and close your toes to engage muscles (20 repetitions).
- Calf Stretch: Lean against a wall to stretch calf muscles (30 seconds, 3 repetitions).
Performed regularly, these exercises support foot health and alleviate flat feet-related discomfort. For example, a patient doing 10 minutes of morning exercises may significantly reduce pain.
