Under Armour size chart

Under Armour’s own size charts cover men’s 7–16, women’s 5–12, kids 1K–7.

Under Armour runs large in men’s shoes, against 23 other brands’ charts: size for size, its chart is made for a longer foot than another brand’s 58% of the time, about the same (within 2.5 mm) 33% and a shorter one 9%, typically by half a size. Go about half a size down from the size you wear in most brands, or size from your foot length on its chart.

Under Armour’s charts at a glance

Chart	Sizes	Foot lengths

Women’s	5–12	22.5–28.5 cm
Kids	1K–7	7.0–25.0 cm

Does Under Armour run big or small?

From Under Armour’s 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, Under Armour’s chart gives a US size a size to 1½ sizes smaller for 11 of 12 foot lengths from 24.0 to 30.0 cm: its sizes allow a longer foot than the standard ones.

For example, Under Armour’s men’s US 9 is for a foot up to 27.0 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: 11 for a shorter foot than Under Armour’s, 10 for about the same (within 1 mm) and 2 for a longer one.

Charts that size like Under Armour’s: Saucony, Timberland, Vans, UGG, Dr. Martens, Fila, New Balance and Crocs. Charts that size like the standard tables: Nike, adidas, HEYDUDE, KEEN, SOREL, HOKA, ANTA, Clarks and Reebok.

Women’s

Under Armour 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 44% of the time, about the same (within 2.5 mm) 35% and a shorter one 21%. Your usual US size is a good start; check your foot length on its chart.

Against the standard size tables, Under Armour’s chart gives a US size half a size to 1½ sizes 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, Under Armour’s women’s US 8 is for a foot up to 24.5 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: 4 for a shorter foot than Under Armour’s, 8 for about the same (within 1 mm) and 9 for a longer one.

Charts that size like Under Armour’s: Salomon, Saucony, Timberland, Vans, UGG, adidas, SOREL, Teva, Veja, Golden Goose and ANTA. Charts that size like the standard tables: KEEN, Clarks, Crocs and Reebok.
