Fitting FAQ

Common questions about New Balance sizing and fit — answered.

Do New Balance shoes run true to size?
Generally, yes — New Balance shoes run true to US sizing. However, some models may fit slightly longer. If you're between sizes we recommend sizing up by half a size, especially in 608 and 624 models.
Are New Balance shoes good for nurses and healthcare workers?
Absolutely. New Balance shoes are a top choice in healthcare thanks to their wide-width options, cushioned soles, and all-day comfort. Models like the 608 and 624 are particularly popular among nurses, aged care workers, and hospital staff who spend long hours on their feet.
What width should I choose?
If you've never bought wide-fit shoes before, start with the standard width — D for men, B for women. If your feet feel cramped or spill over the sole edge, go up one width. New Balance's 2E and 4E wide options are great for people with bunions, swollen feet, or orthotics.
Are Australian sizes the same as US sizes for New Balance?
For women's sizing, AU and US sizes are the same. Men's AU sizes are 0.5–1 size smaller than US sizes (an AU 9 = US 9.5 approximately). However, New Balance shoes sold in Australia are labelled in US sizing, so the size on the box is what you'll find on our product pages.
Can I use orthotics with New Balance shoes?
Yes — many New Balance models have a removable insole, allowing you to replace it with your own orthotics. If you use custom orthotics, consider going up a width (e.g. from D to 2E) to accommodate the added volume.
How do I measure my foot at home?
Trace your foot on a piece of paper while standing, then measure the longest point (heel to toe) in centimetres. Compare to our CM column in the size charts above. Always measure both feet and fit to the larger one.
