Adidas Shoe Size Chart

Adidas shoe size guide at a glance#

A men’s adidas US 9 is a UK 8.5 / EU 42 2/3 and fits a 10.4 in (26.3 cm) foot. Women’s run one US size higher for the same foot length, so a women’s 8 and a men’s 7 are both 9.7 in (24.6 cm). Kids’ K sizes run 1k to 13.5k, then youth 1 to 7.5. Measure heel to toe and match the inches or cm column below.

• UK sizes run half a size below US across all adidas charts: a US 10 is a UK 9.5.
• K sizes are kids’ sizes: 4k = 4.2 in (10.6 cm), 9k = 6 in (15.3 cm), 13k = 7.4 in (18.8 cm).
• Big kids’ 3.5 to 7.5 overlap adult sizing: a big kids’ 6.5 and a women’s 7.5 are both 9.5 in (24.2 cm).

Adidas shoes generally run true to size, though it varies by style. When in doubt, go by foot length in centimeters, not by the size you wear in another brand, or let our shoe size recommender convert from a brand you already know fits.

What do adidas K sizes mean?#

The k stands for kids. Adidas kids’ sizes run 1k to 13.5k before switching to youth sizes 1 to 7.5. Sizes 1k to 10k cover babies and toddlers (about ages 0 to 3); 10.5k to 3 cover children (about ages 4 to 7). Common K sizes by foot length: 4k = 4.2 in (10.6 cm), 5k = 4.5 in (11.5 cm), 6k = 5 in (12.8 cm), 9k = 6 in (15.3 cm), 11k = 6.7 in (17 cm), 12k = 7 in (17.8 cm), 13k = 7.4 in (18.8 cm). UK kids’ sizes run half a size behind US, so a UK 13k (US 13.5k) is 7.5 in (19.1 cm).

Frequently asked questions#

Do adidas shoes run true to size?#

Adidas shoes generally run true to size, but it varies by style. Go by foot length: measure heel to toe in centimeters and match the chart for your range.

How do I measure my foot for adidas shoes?#

Stand on a piece of paper, mark your heel and the tip of your longest toe, then measure the distance between the marks. Compare that length to the inches or cm column.

Should I size up or down if I’m between sizes?#

Size up. A little extra room is more comfortable than a shoe that presses on your toes.

What size is a big kids’ 6.5 in women’s?#

A big kids’ 6.5 is 9.5 in (24.2 cm), which matches a women’s 7.5 in adidas sizing.

Sizing tips#

• Measure both feet and fit the larger one; one foot is usually slightly longer.
• Leave growing room for kids: about a thumb’s width beyond the longest toe, but no more, or the shoe will slip.
• Think about socks: thicker sports socks can push you up half a size.
