What Are Flat Feet?
Flat feet — also known as pes planus or fallen arches — is a condition in which the arches on the inside of the feet are significantly reduced or absent, causing the entire sole of the foot to make contact with the floor when standing. In a normal foot, the arch acts as a natural shock absorber, distributing body weight across the foot and reducing the impact on bones, joints, and soft tissues during movement. When this arch is flattened, the foot loses much of its natural cushioning ability.
Flat feet are extremely common and can be present in either one or both feet. In many children, flat feet are a normal part of development — the arches typically form between ages 3 and 10. In some children, the arches never fully develop, a condition that may or may not cause symptoms as they grow into adulthood. Flat feet can also develop later in life due to injury, pregnancy-related weight gain, aging, obesity, or conditions affecting the tendons that support the arch, such as posterior tibial tendon dysfunction (PTTD).
There are two types of flat feet: flexible flat feet, in which the arch appears when the foot is not bearing weight but flattens when standing, and rigid flat feet, in which there is no arch regardless of weight-bearing. Flexible flat feet are far more common and are generally easier to manage. Rigid flat feet may indicate a more complex underlying structural or neurological issue.
Symptoms of Flat Feet
Many people with flat feet have no symptoms at all. However, others experience pain or aching in the arch or heel area, swelling along the inner ankle, leg fatigue or cramping during prolonged standing or walking, knee, hip, or lower back pain caused by changes in alignment, and difficulty standing on tiptoe. The inward rolling of the foot associated with flat feet — known as overpronation — can place abnormal stress on the ankle, knee, hip, and lumbar spine over time, making the condition a contributing factor in a wide range of musculoskeletal problems beyond the foot itself.
Flat Feet Treatment Options
At Comprehensive Podiatry Associates, P.C. Foot Specialists in , treatment for flat feet is tailored to whether your flat feet are causing symptoms and to what degree they affect your daily function. For patients with mild or asymptomatic flat feet, monitoring and supportive footwear may be all that is needed. For those experiencing pain or functional limitations, treatment options include custom orthotics designed to support the arch and control overpronation, stretching and strengthening exercises targeting the calf, Achilles tendon, and foot muscles, supportive footwear recommendations, physical therapy, and anti-inflammatory medications for acute pain episodes. In rare cases involving rigid flat feet or severe posterior tibial tendon dysfunction unresponsive to conservative care, surgical reconstruction may be considered.
Frequently Asked Questions About Flat Feet
Are flat feet a serious condition?
Flat feet are not inherently serious, and many people with flat feet live without any significant discomfort. However, when flat feet cause pain, fatigue, or alignment issues that affect the ankles, knees, hips, or back, they warrant professional treatment. Left unaddressed, the biomechanical changes associated with flat feet can lead to a range of secondary problems over time.
What causes flat feet in adults?
In adults, flat feet can develop due to age-related changes in the tendons that support the arch, obesity, injury, prolonged standing on hard surfaces, pregnancy, or a progressive condition called posterior tibial tendon dysfunction in which the main tendon supporting the arch weakens and eventually fails. Some adults simply never developed arches fully during childhood.
Can flat feet cause knee or back pain?
Yes. Flat feet cause overpronation — an inward rolling of the foot and ankle — which misaligns the entire kinetic chain from the foot up through the knee, hip, and lower back. Over time, this misalignment can contribute to knee pain, hip bursitis, and chronic low back pain. Correcting the foot mechanics with custom orthotics can significantly reduce stress on these joints.
Do children outgrow flat feet?
Many children with flexible flat feet develop normal arches by age 8 to 10. However, if flat feet persist into the teenage years, cause pain or difficulty with activity, or are associated with a rigid structure rather than flexible collapse, a podiatric evaluation is recommended to determine whether intervention is needed.
Can custom orthotics fix flat feet?
Custom orthotics cannot structurally rebuild an arch, but they are highly effective at supporting the arch, controlling overpronation, and relieving the pain and secondary problems associated with flat feet. For many patients, orthotics combined with appropriate footwear and exercise provide significant long-term relief.
What type of shoes are best for flat feet?
Motion control or stability shoes with firm midsoles, strong arch support, and a wide base are generally best for people with flat feet. Avoid flat, unsupportive footwear like flip-flops or minimalist shoes that offer no arch support. Our team can provide specific footwear guidance based on your degree of flat foot and activity level.
When should I see a podiatrist for flat feet?
You should see a podiatrist if flat feet are causing foot, ankle, knee, hip, or back pain, if you are experiencing leg fatigue or cramping with normal activity, if your foot is visibly turning inward when you walk, or if your child complains of foot pain or is avoiding physical activity due to discomfort. Early evaluation helps prevent secondary complications from developing.
