adidas size chart

adidas’ own size charts cover men’s 4–20, women’s 5–15.5, toddler 1k–10k, little kid 10.5k–3, big kid 3.5–7.5, plus charts for football boots.

adidas runs small in men’s shoes, against 23 other brands’ charts: size for size, its chart is made for a longer foot than another brand’s 2% of the time, about the same (within 2.5 mm) 42% and a shorter one 55%, typically by half a size. Go about half a size up from the size you wear in most brands, or size from your foot length on its chart.

Does adidas run big or small?

From adidas’ own foot lengths: first against the other brands’ charts, size for size (whether a US size is made for a longer or shorter foot than theirs), then against the standard size tables, foot by foot. Brands measure differently (Nike’s chart, for one, prints a box size in centimetres beside the foot length and says the two differ), so this is what each chart advises, not a fit test.

Men’s

Against the standard size tables, adidas’ chart gives the same US size for 10 of 13 foot lengths from 24.0 to 30.0 cm (for the other 3, half a size smaller).

For example, adidas’ men’s US 9 is for a foot up to 26.3 cm (the standard US 9: 26.25 cm). The other 23 brands’ charts make it for a foot from 26.0 to 27.7 cm: 3 for a shorter foot than adidas’, 5 for about the same (within 1 mm) and 15 for a longer one.

Charts that size like adidas’: Nike, HEYDUDE, KEEN, SOREL, HOKA, ANTA, Clarks and Reebok.

Women’s

adidas sits in the middle in women’s shoes, against 21 other brands’ charts: size for size, its chart is made for a longer foot than another brand’s 24% of the time, about the same (within 2.5 mm) 47% and a shorter one 29%. Your usual US size is a good start; check your foot length on its chart.

Against the standard size tables, adidas’ chart gives a US size half a size to a size smaller for 12 of 12 foot lengths from 22.0 to 27.5 cm: its sizes allow a longer foot than the standard ones.

For example, adidas’ women’s US 8 is for a foot up to 24.6 cm (the standard US 8: 24.1 cm). The other 21 brands’ charts make it for a foot from 24.0 to 25.3 cm: 5 for a shorter foot than adidas’, 8 for about the same (within 1 mm) and 8 for a longer one.

Charts that size like adidas’: Nike, Salomon, HEYDUDE, SOREL, Veja, HOKA, ANTA and Under Armour. Charts that size like the standard tables: KEEN, Clarks, Crocs and Reebok.

adidas’ own advice, on its chart: “In between sizes: tight fit go one size down, loose fit go one size up”.
