Give your children the gift of healthy feet: Healthy feet make for happy toes, and more importantly, happy children. 
Growing feet are developing feet
A baby’s foot contains more cartilage than bone, which, over time, will fuse and harden into adult bones. Although the structure of the foot develops fully by the first 2 years, the bones themselves will not fully develop and harden until around the age of 18. If the cartilage is deformed by badly shaped or rigid shoes, the bones will take on the deformed shape. More than 80% of foot problems, bunions and injuries are a result of misshaped and inflexible shoes. It’s vital that kid’s shoes allow enough room for natural growth, until the foot bones mature.  This is why it is crucial to have good shoes early on, so that the bones are allowed to develop naturally.
