How to Measure Your Foot
Not sure of your shoe size, or buying for someone else? A quick foot measurement takes twominutes and removes the guesswork.
- Measure in the afternoon. Feet swell slightly through the day, so an afternoon measurement gives the truest fit.
- Stand on a piece of paper. Place a sheet of A4 on a hard floor (not carpet) and stand on it in the socks you'll usually wear.
- Trace your foot. Hold a pencil upright at 90° and trace around the longest foot — most people have one foot slightly larger.
- Measure heel to longest toe. Use a ruler to measure the longest distance on your tracing in centimetres.
- Match to the chart. Compare your foot length to your shoe size, then choose the matching sock size in the adults' table above.
Tip: if you're between sizes or have wide feet, choose the larger size for comfort.
