Frequently Asked Questions
Why do Nike and adidas give me different sizes for the same foot?
Each brand grades its charts differently. adidas publishes finer 0.4–0.5 cm steps; Nike uses even half-centimetre steps. The same foot can sit on different numbered rows — compare the covered foot range, not just the number.
My foot is between two official rows — which do I take?
Most people go up when between sizes, but last shape matters more: narrow lasts (e.g. some adidas models) often need the upper row, roomy lasts can go down. Check the model's own chart.
Are these official charts?
Yes — each row links to the brand's own size-chart page, and every dataset shows the date it was last verified. We do not scrape; values are maintained by hand.
What about EU or UK sizes?
This tool compares on US sizes because every carried brand publishes a US column. For system conversion, use the general shoe-size converter.
Lookup intervals are calculated from adjacent row midpoints, not official fit ranges. All values come from each brand's published size chart and are manually maintained — last check dates are shown per brand. Last shapes differ between models, so treat the result as a starting point and confirm on the product page. · Shoe size converter · Read our fashion coverage
