Advice from PodiatryNZ
Great care should be taken with your child’s feet as they can be at risk from injury and deformity due to ill-fitting footwear and general activity.
The main difference between a child’s foot and an adult foot is that it grows. This means the child may suffer from foot and lower limb problems at different ages as they continue to develop and grow. Only once the arch is properly developed (usually around 8 – 10 years) will your child be able to develop an adult walking motion. Even when your child’s foot looks like an adults it is still vulnerable.
Having shoes that are the correct shape and fit is vital. You need the right shoe for the job.
