Flat feet, also known as "pes planus," occur when the arches of the feet are low or absent. This condition is often associated with excessive pronation, where the foot and ankle roll inward excessively during weight-bearing activities. In young children, flat feet are considered part of the developmental process, and the arch typically forms gradually as they begin walking. Most children develop a natural arch by the age of six, although some may retain flat feet into adolescence and adulthood.
Causes and Risk Factors of Flat Feet in Children
Developmental Factors: Many children are born with flat feet, and arches typically develop as they grow.
Genetics: A family history of flat feet increases the likelihood of the condition.
Joint Hypermobility: Excessive joint flexibility, often seen in children, can contribute to flat feet.
Low Muscle Tone: Poor muscle tone in the foot can delay proper arch formation.
Neurological Conditions: Disorders such as cerebral palsy or muscular dystrophy can lead to flat feet.
Congenital Foot Deformities: Conditions like tarsal coalition or vertical talus can cause flat feet.

Signs and Symptoms of Flat Feet in Children
Visible Flattening of the Arch: The foot may appear flat, especially when standing.
Pain or Discomfort: Pain in the feet, legs, or knees due to poor alignment, especially after prolonged walking or standing.
Fatigue: The child may tire easily when walking or running.
Dislikes Walking: Frequently asks to be carried due to discomfort or fatigue.
Difficulty with Balance: Flat feet can affect balance, leading to clumsiness or frequent tripping.
Uneven Shoe Wear: Shoes may wear out unevenly, requiring frequent replacements.
Postural Changes: Misalignment in the knees, hips, or lower back, causing poor posture.
Treatment and Management of Flat Feet in Children
You should consider seeking treatment for your child's flat feet if they experience pain or discomfort in their lower limbs, especially after walking or standing for long periods. Treatment may also be necessary if your child has difficulty with balance or coordination, frequently trips, or avoids physical activity due to fatigue or discomfort. Additionally, if flat feet contribute to postural problems or misalignment in the knees, hips, or lower back, it's a good idea to consult a podiatrist for evaluation.
If treatment is recommended, options can include:
Orthotic Devices: Customised insoles, ankle foot orthoses, or supramalleolar orthoses are used to support the foot and improve lower limb alignment.
Supportive Footwear: Shoes with adequate pronation control and cushioning to reduce foot strain and increase comfort.
Stretching and Strengthening Exercises: Exercises to stretch tight muscles and strengthen weak foot and leg muscles, improving function and reducing pain.
