New Balance runs true to size for most people, with a slightly roomier toe box than Nike or Adidas. Use the tables below to convert between US, UK, EU and CM (foot length) sizing before you order. If you’re between two sizes, or want the full fit breakdown by model, see our New Balance sizing guide.

How to Use This Chart
Measure your foot length in centimeters from heel to the tip of your longest toe, in the afternoon when feet are slightly swollen, and match it to the CM column — this is more accurate than converting from a size you wear in another brand. New Balance also offers Narrow (B), Standard (D), Wide (2E) and X-Wide (4E) widths on most men’s styles, and Narrow (2A), Standard (B), Wide (D) and X-Wide (2E) on women’s styles, so if your foot is wider or narrower than average, size length using this chart first and then choose the matching width.
Frequently Asked Questions
Does New Balance run true to size?
Yes, most New Balance styles run true to size in length. The fit is generally roomier through the toe box than Nike or Adidas, which is why some wearers who size down in other brands find their true New Balance size more comfortable.
Is New Balance sizing the same for men and women?
No. Women’s New Balance shoes are built on a dedicated women’s last, not simply a relabeled men’s size. Use the women’s table above rather than converting from the men’s chart.
What EU size is a US men’s 10 in New Balance?
A US men’s 10 converts to EU 44, UK 9.5, and 28 cm foot length.
