Flat Feet
Feet with little or no arch, so the whole sole rests on the ground — often painless, but supportive shoes and exercises help when they ache.
📝 Summary
In short: Feet with little or no arch, so the whole sole rests on the ground — often painless, but supportive shoes and exercises help when they ache.
Common causes: A naturally low arch that never fully formed in childhood; Stretching or weakening of the tendon that supports the arch with age; Being overweight, pregnancy, or long hours on hard floors.
First thing to try: Wear supportive, well-fitted shoes with good arch support, or add cushioned insoles.
See a doctor if: Foot or ankle pain that limits walking despite supportive shoes
🌿 Overview
Flat feet means the arch on the inside of the foot is low or absent, letting most of the sole touch the floor when standing. Many people have flat feet their whole lives with no trouble at all. When they do cause aching, tired feet, or ankle and knee strain, supportive footwear and simple strengthening exercises usually bring relief.
The arch acts like a spring, soaking up shock with every step. Some people never develop a normal arch in childhood; in others the arch falls later in life as the supporting tendon stretches or weakens. Flat feet may cause aching along the inner foot and ankle, tired legs after standing, and uneven shoe wear.
Most flat feet need no treatment. When they hurt, the goal is to support the arch and strengthen the muscles that hold it: well-fitted shoes with good arch support or insoles, calf and foot stretches, and easing inflammationThe body's natural response to injury — like redness, swelling, or heat around a sore spot. More → with rest and ice or warmth. A suddenly flattening, painful arch in an adult deserves a check, as it can mean a stretched or torn tendon.
