Causes of Flat Feet
Foot shape and arch type have a strong hereditary component, but a number of conditions and events can cause or contribute to flat feet:
- A posterior tibial tendon tear can cause the arches to fall.
- Obesity and pregnancy put excessive stress on the arches and tendons and cause the arch to flatten.
- Systemic conditions such as rheumatoid arthritis and diabetes can also lead to fallen arches and flat feet.
- A flattening of the arch often occurs as a result of the aging process.
