Check your children’s shoe fit frequently to avoid foot problems. Children’s feet often grow faster than parents expect, and tight shoes can lead to lasting foot problems. Make a point of checking shoe fit every few weeks, experts recommend. Check shoe fit while a child is standing. Philip Wilson, an orthopedic surgeon at University of Texas Southwestern Medical Center, tells parents to allow for half the length of an adult thumbnail between the tips of the toes and the front of the shoes. If there’s less space, buy new shoes. Infants generally don’t need shoes except in cold weather.
