Pediatric flat foot, also known as fallen arches, is a condition where the entire sole of the child’s foot contacts the ground. The sole of the foot has an arch on the inner side that extends from the heel to the base of the big toe. The foot is called flat when it does not have this arch.
It’s a normal condition that almost all babies and young children have. In infants, the baby fat pad in the foot hides the developing arch. Young children have flat feet because they are loose jointed. Most children show the sole arch around the age of six except for one or two in 10 children who might never develop an arch. However, this doesn’t mean that they will have problems with physical activities, sports, or feel any pain.
A study was conducted to investigate the prevalence of flat foot in school children where 835 kids were scanned. The age range was between three to six years old. The results showed that 44% of the kids have flexible flat foot. The study also concluded that flat foot is affected by factors as age, gender, and weight.
- In the three-year-old children group, 54% showed flat foot, while the percentage in the six-year-old group was 24%.
- The prevalence of flat foot was 52% in boys and 36% in girls which shows that boys have a higher tendency for flat foot.
- 13% of the kids with flat foot were overweight or obese.

- Stretching of the tissues in the feet due to a foot or ankle injury or gaining excess weight.
- Conditions affecting the muscles, nerves, and joints.
- The bones of the feet didn’t grow properly in the womb.

There is a lot of controversy regarding the urgency and effectiveness of surgery in some flat feet cases. However, there are some non-surgical treatments that can be applied. They won’t change the shape of the feet but will help get rid of the painful or limiting symptoms:
