Step-by-step
HOW TO MEASURE
YOUR FOOT.
01
Prep your materials
Place a piece of paper on a hard floor. Stand on it with your heel touching the wall.
02
Mark the longest point
Mark the tip of your longest toe (usually the big toe) with a pencil.
03
Measure in mm
Measure from the wall edge to your mark. Use millimetres for the most accurate match.
04
Find your size
Cross-reference your measurement in the MM column above. When between sizes, size up.
MEASURE HEEL TO LONGEST TOE
The blue arrow shows the measurement you need. Stand upright with full weight on the foot — do not measure sitting down.
SIZING TIPS
Measure in the afternoon
Feet swell throughout the day — afternoon gives the most accurate fit.
Wear your usual socks
Crocs are worn without socks but if you layer, measure accordingly.
Check both feet
Measure both feet and use the larger measurement to select your size.
Crocs run true to size
For a standard fit choose your regular size. For a roomier feel, size up.
