5. Measure the length and width of your foot. Using your ruler, measure the inches between the two parallel lines on either side of your foot: top to bottom and side to side. Note these two numbers.
6. Subtract 3/16 of an inch from each number. This just accommodates for the tiny bit of extra space between your foot and the straight lines.
