Reasons Flat Feet Occur

Pes planus is the medical term for the condition known as flat feet. Flat feet are also referred to as fallen arches and are common among infants and young children. Most babies are born with flat feet, and their arches begin to develop between the ages of 2 and 3. Studies show the most common type of flat feet is flexible flat feet. With this condition, the arch is visible when the foot is lifted and disappears when the foot is placed on the ground. An injury can also cause additional problems like posterior tibial tendon dysfunction, which generally occurs during adulthood. The tendons that support the arch can become weak and flat from a lack of adequate support. Flat feet can be caused by genetic reasons or possibly from existing medical conditions, such as cerebral palsy. If you have this foot condition, it is suggested that you consult with a podiatrist who can offer you treatment options, which may include wearing custom-made orthotics.

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.  


  • Pain around the heel or arch area
  • Trouble standing on the tip toe
  • Swelling around the inside of the ankle
