Flat feet, also called pes planus, is a foot deformity condition associated with the collapse or absence of the foot arch that supports the body weight while standing. People who have flatfeet have foot that point outward when they stand up, and the whole soles of their feet touch the ground.
When the arches do not form during childhood, flatfeet may result. It can also appear later in life due to an injury or the natural wear-and-tear strains of becoming older.
Typically, flatfeet are painless. There is no need for treatment if you are pain-free. A specialist’s assessment may be necessary if your flatfeet are painful and restricting your activities.


Patients with flatfeet usually do not experience any symptoms. However, some persons with flat feet have foot pain, particularly in the heel or arch region. With activity, pain could get worse. Along the inside of the ankle, swelling could develop.
If you or a member of your family suffers from foot discomfort, especially if it prevents you from doing things you want to, consult your doctor.


Because the foot’s arch has not yet formed, flatfeet are common in infants and toddlers. Most individual’s arches form throughout childhood, but some people never do. Those without arches could or could not experience issues.
Some kids have flexible flatfeet, also known as flexible flatfoot, where the arch is only noticeable when the kid is sitting or standing on their tiptoes and vanishes when the kid is standing. The majority of kids grow out of flexible flatfeet without any issues.
The syndrome can also develop in people who don’t have flat feet. Arches that have been injured may suddenly fall. Or the collapse can occur after years of deterioration. The tendon that supports the arch and runs along the inside of the ankle might weaken or tear over time. Arthritis in the foot could occur as the severity rises.
