Doctors argue that most foot problems and pains in adulthood stem from ill-fitting shoes or poor foot experiences during childhood. It is important to remember that the foot is not a separate entity, but an integral body part that supports the entire skeletal structure. Ill-fitting shoes put the child at risk for injury or deformity later in life. Many problems with posture, walking, and even back pain can be associated with ill-fitting or poorly made shoes. In the long run, good shoes are a good investment.
