Kids' Fit Tips

1. Your child’s feet are constantly growing! Be sure to make sure their shoes fit properly every two to three months.
2. Kids’ shoes should have ¼" of wiggle room in the toe area. This allows room to grow and helps with balance. A snug fit is also important to keep your child from slipping out of his/her shoes.
3. Often brands size their shoes differently, and you may see fit recommendations for certain styles. If you are accustomed to the brand, please purchase the size you normally buy. If not, please consider our recommendations.
4. It is normal for a child to have one foot larger than the other. Order shoes to the larger foot.
5. If no narrow sizes are available, you may wish to order a ½ size down.
6. If no wide sizes are available, you may wish to order a ½ size up.
7. If your child is in between sizes, we recommend ordering the next ½ size up.
