Nike vs Reebok: common questions

Does Reebok run bigger or smaller than Nike?

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

Can I buy Reebok in my Nike 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 Nike size to Reebok?

Find your Nike 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.
