How to measure the length of your foot - instructions in 4 steps

1. Prepare a sheet of paper and set it on a hard, non-slippery surface - it is best to tape it to the floor.

2 Stand barefoot on a piece of paper - distribute your body weight evenly and set your foot straight.

3. Mark the tip of the big toe and the back of the heel - preferably holding the pencil vertically.

4. Take off the foot and measure the distance between the marks - this is the length of the foot. Repeat for the other foot and choose a larger measurement, matching it to the size chart.
