Adidas vs New Balance: common questions

Does New Balance run bigger or smaller than Adidas?

New Balance runs about a full size bigger than Adidas: the same foot takes a lower number in New Balance, consistently across the size range. For example, an Adidas US 10 maps to a New Balance US 9.

Can I buy New Balance in my Adidas size?

No. The number on the box means a different foot length in each brand, which is why a straight size-for-size swap misfits. Use the table above or the converter to translate properly.

How do I convert my Adidas size to New Balance?

Find your Adidas size in the table above and read across, or use the converter with your exact size. The most reliable method is your measured foot length in centimeters: both brands publish their charts against it, so it translates without guesswork. Half sizes round to the nearest size the brand actually makes.
