How to Measure Foot Size

• Place a piece of paper to a flat floor, ensuring the paper doesn’t slip. If needed Tape the paper to avoid slipping.
• Stand with one foot on the paper or do this sitting in a chair, just make sure the  foot is firmly planted on the paper..
• With a pen or pencil mark the tip of the big toe and the outermost part of the heel 
• Repeat the process with the other foot. It’s common for a person’s feet to be two slightly different sizes. If your feet are different sizes then use the measurement of the larger foot.
