Updated for 2026 — This article has been reviewed and updated with the latest recommendations.
Most kids under six have flat feet, and that is completely normal. The arch develops over time. But for some children, the arch never fully develops, leading to discomfort, fatigue, and sometimes knee or hip pain during activity. The right shoes provide gentle support that keeps the foot aligned without forcing an arch.

Orthotics and What to Avoid
For most kids with flexible flat feet and no pain, supportive shoes are sufficient. If pain occurs, see a pediatric podiatrist.
Over-the-counter insoles from Superfeet or PowerStep ($20 to $35) are a good middle ground. Avoid flat shoes with no structure, flip-flops, and hand-me-down shoes that are molded to another foot shape.
How Flat Feet Develop in Children
When babies are born, they all have flat feet. The fat pad in the arch area is thick, and the bones, muscles, and tendons have not yet developed the structural support needed to form an arch.
Between ages 3 and 6, the arch gradually appears as the child walks, runs, and climbs. By age 6 to 8, most children have developed a visible arch. For about 20 percent of children, the arch remains flat into adolescence and adulthood.
Flexible flat feet, where the arch appears when the child sits or stands on tiptoe but disappears when standing flat, is the most common type and is usually not a cause for concern. Rigid flat feet, where no arch appears in any position, are less common and may warrant medical evaluation. The distinction matters because flexible flat feet rarely cause problems beyond mild fatigue, while rigid flat feet can sometimes indicate structural issues that benefit from early intervention.
Activities That Strengthen Foot Arches
Beyond wearing the right shoes, certain activities naturally strengthen the muscles that support the arch.
Walking barefoot on sand or grass (not hard surfaces) allows the foot muscles to work freely and develop strength. Toe curls, where the child picks up small objects like marbles or a towel with their toes, strengthen the intrinsic foot muscles. Standing on one foot for balance helps develop the stabilizer muscles throughout the foot and ankle.
Swimming, climbing, and general active play all contribute to foot development.
The worst thing for developing feet is prolonged sitting and always wearing rigid shoes that do not allow any foot muscle engagement. Structured shoes are important for activities like sports and long walks, but unstructured time for the feet, like playing barefoot in the yard, is beneficial too.
Growth and Re-evaluation
Because children's feet are still developing, it is worth re-evaluating the situation every year or two with a pediatrician or podiatrist.
Some children who have flat feet at age 5 will develop a normal arch by age 10. Others will have flat feet for life, which is perfectly fine as long as it does not cause pain or functional limitations. The shoe needs may change as the child grows, so what works at age 6 might need to be reassessed at age 9. Stay attentive to any complaints of pain and adjust footwear accordingly.
Final Thoughts

Whether you are just getting started or looking to optimize an existing setup, the principles covered here apply across experience levels. Do not let perfect be the enemy of good. Starting with a solid foundation and making incremental improvements over time is a much more effective strategy than waiting until you have everything figured out before taking any action at all.
