Progressive collapsing foot deformity, also known as adult-acquired flatfoot, occurs when the arch gradually collapses, leading to changes in your foot’s shape and function. Adult-acquired flatfoot often results from dysfunction in the posterior tibial tendon, which plays a key role in supporting the arch and turning the foot inward. As this tendon weakens, the foot may flatten, and the alignment of the ankle can shift, sometimes causing pain or difficulty walking. Aging, previous injuries, obesity, diabetes, or arthritis may contribute to the development of adult-acquired flatfoot. It may result in pain along the inside of the ankle, swelling, or an outward shift of the foot’s position. A podiatrist can assess the severity of the condition using certain imaging tests to determine the best course of treatment. Supportive devices, orthotic inserts, and in more advanced cases, surgery, may help restore function and relieve pain. If you notice that your feet have become flatter, it is suggested that you schedule an appointment with a podiatrist for an exam, diagnosis, and treatment options.

Flatfoot is a condition many people suffer from. If you have flat feet, contact one of our podiatrists from Ankle & Foot Care Center. Our doctors will treat your foot and ankle needs.

What Are Flat Feet?

Flatfoot is a condition in which the arch of the foot is depressed and the sole of the foot is almost completely in contact with the ground. About 20-30% of the population generally has flat feet because their arches never formed during growth.

Conditions & Problems:

Having flat feet makes it difficult to run or walk because of the stress placed on the ankles.

Alignment – The general alignment of your legs can be disrupted, because the ankles move inward which can cause major discomfort.

Knees – If you have complications with your knees, flat feet can be a contributor to arthritis in that area.  

Symptoms

• Pain around the heel or arch area
• Trouble standing on the tip toe
• Swelling around the inside of the ankle
• Flat look to one or both feet
• Having your shoes feel uneven when worn

Treatment

If you are experiencing pain and stress on the foot you may weaken the posterior tibial tendon, which runs around the inside of the ankle.
