Flatfoot, also known as pes planus, is a condition where the arches of the feet are lowered or absent, causing the entire sole to make contact with the ground. This can lead to discomfort and pain in the feet, ankles, and legs, especially after prolonged standing or walking. Flatfoot can be present at birth or develop over time due to factors like injury, obesity, or aging. Most people with flatfoot do not experience significant issues, but some may require treatment. Options include supportive footwear, orthotic inserts, and physical therapy to strengthen the foot muscles. In severe cases, surgery may be considered to correct the alignment of the foot.
