While you are usually born with flat feet, there can be reasons why you have flat feet as an adult. These include the following:
- You can have an injury to the ankle or foot that disrupts the supporting ligaments of the foot arch.
– You can be very overweight, which puts excess pressure on the arches to hold your body up.
– You can suffer from rheumatoid arthritis, which deforms the joints of the foot, flattening out the foot in the process.
– The incidence of flat feet increases as you age because the strength of the ligaments is not as great and the feet flatten out.
