You need two sheets of paper (DIN A4), a pencil and a ruler.

That’s how it’s done: we recommend using a pencil or a ball pen. A thick pen, such as a felt-tip or marker, can distort the result.

Place the sheets of paper on the floor. Stand straight on the paper with your heels against the wall.

Measure the length: mark the longest toe of each foot.

Measure the width: with the help of a pencil, mark the outermost points at the left and right side of the balls of your feet.
