New Balance vs Nike: common questions
Does Nike run bigger or smaller than New Balance?
Nike runs about a full size smaller than New Balance: the same foot takes a higher number in Nike, consistently across the size range. For example, a New Balance US 10 maps to a Nike US 11.
Can I buy Nike in my New Balance 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 New Balance size to Nike?
Find your New Balance 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.
