How to take an accurate foot measurement: 

1. Place a piece of paper on a hard floor, against the wall 

2. Stand barefoot on the paper with your heel against the wall 

3. Make sure the paper has not shifted and is still flat and against the wall 

4. Draw a line on the paper at the tip of your longest toe 

5. Measure the distance between the edge of the paper that was against the wall and the line you drew, in Millimetres

 6. Do this again with the other foot *Use the measurement of your biggest foot (for most people, a foot will be slightly bigger than the other)
