- Avoid a fit that is too big, unless shoes will not be worn until the child's foot grows into them. Poor-fitting shoes can damage feet.
- It is not uncommon for a child to have one foot larger than the other. Fit to the larger foot.
- If between sizes, we recommend you order 1/2 size up.
- Have the child try out the shoes indoors, walking on carpeted surfaces wearing socks normally worn. Make sure there is room for the toes to wiggle a bit.
