1. Stand upright with your foot on an A4 piece of paper. Don't sit. This will result in an inaccurate foot length measurement.

2. Have another person trace around the circumference of your foot using a thin barreled pen or pencil. Ensure you hold the pen in an upright position.

3. Draw a horizontal line at both the top and bottom extremeties of your foot tracing.

4. Draw a perpendicular line between these two horizontal line and measure the distance.

5. Double check this measurement by standing on a hard surfaced floor with your heel against a wall with no skirting board. Draw a line at the tip of your longest toe and measure the distance between the wall and the mark.
