Nike Shoe Size Chart
Nike's own published size chart, covering a 22.5cm to 40cm foot, including a children's chart Nike publishes itself. Every figure below is keyed to a measured foot length rather than converted from another size number. Open the calculator with Nike selected to read it against all 35 brands at once.
Does Nike run small?
No. By its own size chart, Nike sizes in line with most brands in both men's and women's sizes. A 27 cm foot is a men's US 9 in Nike and in 22 of 34 other brands' charts. Charts show how a brand means its sizes to fit, not how any one shoe feels, so read Nike's own fit advice below as well.
| Foot length | Nike | Most common in other brands |
|---|---|---|
| Men's, 25.5 cm | US 7.5 | US 7.5 (20 of 34) |
| Men's, 27 cm | US 9 | US 9 (22 of 34) |
| Men's, 28.5 cm | US 10.5 | US 10.5 (19 of 34) |
| Women's, 23 cm | US 6 | US 6 (14 of 33) |
| Women's, 24 cm | US 7 | US 7 (15 of 34) |
| Women's, 25 cm | US 8 | US 8 (15 of 34) |
How this is worked out: every foot length from 25 to 29 cm (men's) and 22.5 to 26 cm (women's), in 1 mm steps, is read against Nike's chart and the other 34 brands' charts the way the calculator reads them, rounding up between sizes. The answer is the average gap between Nike's size and the size the other brands give most often. See the methodology.

Nike lists two sizes at some foot lengths, because its centimeter column is rounded. Both are shown; the calculator gives the smaller.

How to measure for Nike
Nike states that the CM size on shoe boxes/labels is different from Foot Length (cm).
Nike fit guidance
Measure both feet and use the longer foot. If between sizes, Nike recommends sizing up. Nike does not run a width programme. A small number of models appear in a 2E or 4E men's or D women's wide, but most Nike shoes are made in one width only, and Nike's last runs narrow relative to other brands. If you need width, check the specific model for a wide option rather than assuming one exists. The calculator gives a general estimate for Nike rather than a Nike fitting, because there is no consistent fitting to give.
Where this data comes from
Sizing information reviewed October 2026. Manufacturers revise their charts from time to time, so always confirm against the specific model before buying.
