Key New Balance Sizing & Fitting Rules
- ✓ If your toddler has chubby feet, thick arches, or high insteps, choose Wide (W) or Extra Wide (XW).
- ✓ Remove the insole to visually check toe clearance: your child's longest toe should have about a thumbnail's width (12mm) from the edge.
- ✓ New Balance 574, 990, and Rave Run kids models offer excellent arch support for active children.
Frequently Asked Questions
Helpful fit allowances, measuring wisdom, and sizing advice for parents.
Do New Balance kids shoes run true to size or wide?
New Balance kids shoes generally run true to size in length, but offer a noticeably roomier toe box than narrow athletic brands. They are one of the few footwear makers offering dedicated Wide (W) and Extra-Wide (XW) widths in infant, toddler, and youth models.
How do I know if my child needs New Balance Wide (W) or Extra Wide (XW)?
If standard sneakers leave red pressure marks on the sides of your child's feet, pinky toes, or instep, or if you struggle to fasten velcro straps across the top of their foot, opt for Wide (W) or Extra Wide (XW).
Can I remove New Balance insoles to check sizing?
Yes. Most New Balance children's sneakers have removable insoles. Place your child's foot directly on the removed insert; there should be approximately 12 mm (about half an inch or a thumb's width) of clear space in front of their longest toe.
How do New Balance youth sizes convert to adult women's sizes?
New Balance follows standard US sizing conversions: add 1.5 to the Big Kid / Youth size to find the women's equivalent. For example, a New Balance 5Y corresponds directly to a Women's 6.5.
