This condition is a progressive collapse of the tendons and ligaments that hold up the foot’s arch. This condition most commonly affects women. It typically occurs in only one foot, but in some cases, both feet are afflicted.

Causes:

Adult flat foot typically occurs very gradually. It often develops in an obese person who already has somewhat flat feet. As the person ages, the tendons and ligaments that support the foot begin to lose their strength and elasticity.

Arch Collapses

The posterior tibial tendon, which travels along the inner side of the ankle and into the arch, may begin to gradually stretch and tear. The ligaments of the arch fail, allowing the bones of the foot to slip out of the position and the foot to roll inward. Eventually, the arch collapses completely.

Common Symptoms:

• In many cases, adult flat foot causes no pain
• Aching pain
• Swelling along the inner side of the foot.

Pain Points:

• Arch
• Heel
• Inner side of the foot
