You will need a piece of paper, a pen or pencil, and a ruler or measuring tape.

Look for an area with a hard floor, such as tile or hardwood, where you can comfortably stand and place the paper.

Place the piece of paper flat on the floor. Make sure it's large enough to accommodate your entire foot.

To simulate wearing shoes, put on a thin sock that you would typically wear with the type of shoes you are planning to buy.

Stand up straight with your feet parallel and your weight evenly distributed on both feet. This will ensure an accurate measurement.

Place one foot carefully on the paper, ensuring that your heel is aligned with the edge of the paper.

With the pen or pencil held vertically, trace the outline of your foot, keeping the pen in contact with the paper at all times. Make sure to trace around the widest points of your foot, including the toes and the ball of your foot.
