Pes Planus, also commonly known as "flat feet," is a condition where the arches of the feet are relatively low or non-existent. Flat feet can lead to pain and discomfort for individuals who are active or on their feet for extended periods of time. Some synonyms for Pes Planus include fallen arches, pes valgus, and flat footedness. Exercises and supportive shoes can help alleviate symptoms and improve foot function for those with flat feet. In severe cases, orthotics or surgery may be necessary to correct the condition and provide long-term relief.
