Adidas Shoes Size Chart
By Mohit Patel, Marketing Specialist, Tailor Size Guide
A Adidas men's US 9 is a UK 8.5 and EU 42 2/3, made for a foot about 26.3 cm (10.4 in) long. A women's US 8 is a UK 6.5 and EU 40, for a foot about 24.6 cm.
Adidas uses one combined chart for men and women, with heel to toe length published in both centimetres and inches. Here's the full chart split by men's and women's sizes, how adidas compares with other brands, and how to read its fractional EU sizes.

How Adidas sizes its shoes
Adidas puts men's and women's sizes on one chart, and its women's US sizes are men's US + 1, not the 1.5 most brands use. So an adidas women's 8 is a men's 7. UK sizes are the men's US size minus half a size up to men's 15; above that the chart steps in whole sizes and UK becomes men's US minus 1.
Adidas prints EU sizes in thirds, such as 42 2/3, because it follows the French Paris point scale, where each size is two thirds of a centimetre. The heel to toe length on the chart is the measurement to compare with your own foot.
Adidas men's and women's sizes
By foot length on Adidas's own charts, a Adidas women's US 8 matches a men's US 7, and a men's US 9 matches a women's US 10. Because the converter works through foot length, it uses Adidas's own charts rather than a general rule, so you can trust it for switching between Adidas's men's and women's shoes.
Does Adidas run small or large?
By its chart, Adidas links each size to a shorter foot than most brands: a men's US 9 is for a foot of about 26.3 cm, against a typical 26.8 cm across the 13 brands we cover. So the same foot often needs a bigger Adidas number. For example, a 27 cm foot is a Adidas men's US 10 and a Nike men's US 10. Fit also depends on the model, so check the product page too.

Tips for buying Adidas shoes
- Adidas's own chart advice: for a tighter fit go one size down, for a looser fit go one size up.
- Measure at the end of the day, from your heel to your longest toe.
- When converting adidas women's to men's, subtract 1, not 1.5.
How to measure your foot
Stand on a sheet of paper with your heel against a wall, mark the tip of your longest toe, and measure from the wall to the mark. Do it at the end of the day, in the socks you'll wear, and use your longer foot. Our guide to measuring your shoe size without a Brannock device has step by step photos.
