Crocs Shoe Size Chart

Crocs's own published size chart, covering a 20cm to 35cm foot, including a children's chart Crocs publishes itself, in whole sizes only. Every figure below is keyed to a measured foot length rather than converted from another size number. Open the calculator with Crocs selected to read it against all 35 brands at once.

Does Crocs run small?

Yes. By its own size chart, Crocs runs slightly small in men's sizes and runs a full size to one and a half sizes small in women's sizes. A 24 cm foot is a women's US 7 in 16 of 34 other brands' charts, and a US 8 in Crocs. Charts show how a brand means its sizes to fit, not how any one shoe feels, so read Crocs's own fit advice below as well.

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 Crocs'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 Crocs's size and the size the other brands give most often. See the methodology.

How to measure for Crocs

Crocs come in whole sizes only (no half sizes, except the Custom Cloud model). Measure heel-to-toe standing, using the longer foot.

Crocs fit guidance

Crocs Classic Clogs and most sandals run roomy by design; if your measurement falls between two whole sizes, Crocs and most retailers recommend sizing down to the smaller size for a more secure fit -- the opposite of the usual size-up advice for between-size measurements.

Where this data comes from
