For children with long feet, there are several ways to deal with the situation. First, if the child has only long feet, but walks relatively smoothly, is in a good mental state and is developing normally. This is a physiological phenomenon, often related to parental genetics, and the parents of such children also have long feet and do not need special treatment. Alternatively, if the child has long feet and also has other discomforts, such as very disproportionate body proportions. This condition should be highly suspected to be caused by an inherited metabolic disease, such as Marfan’s syndrome. In addition to the disproportion between the limbs and the body, the child will also have other disorders, such as heart damage, which should be treated promptly with symptomatic support. Because there is no particular solution for inherited metabolic disorders, the main focus is on symptomatic support treatment to prevent serious complications, such as recurrent infections in the child.
