Historical review

For many years, researchers and clinicians believed that individuals with flat feet were at high risk of sustaining a musculoskeletal injury during sports and activities of daily living. Even though this theory was postulated a long time ago, it was revived during the second half of the 20th century when Root et al 1 popularised the concept of ‘ideal feet’. According to those authors, feet that did not fit specific criteria for normalcy were considered abnormal, less efficient and more prone to injury due to many biomechanical compensations. This paradigm became the cornerstone of educational curriculums in health profession education related to the human musculoskeletal system. Consequently, throughout the years and persisting to this day, many healthcare professionals and researchers have perpetuated the belief that flat feet are an important risk factor for musculoskeletal disorders, creating a perceived need for treatment even if no symptoms are present.
