Children under the age of 16 that are wearing adult size shoes inevitably have a smaller arch. If your child’s adult shoe size lands right on the edge of one of our adult sizes the smaller X Brace is usually the correct choice.
If you have an extremely wide or narrow foot and would like additional information about sizing please don’t hesitate to contact us.
