Items needed: pen or pencil, large sheet of paper, tape-measure in millimeters. Measure wearing socks that you will most often wear with these boots. You will be taking measurements of both feet!
Step 1: Place a sheet of paper flat on the floor. Sit on a chair and place one foot on the paper. Apply pressure to your foot and trace the shape of that foot on the paper, carefully holding the pen vertically and perpendicular to the paper, tracing the foot as closely as possible without angling the pen in or out.
Step 2: Using a tape-measure, measure the distance from the very bottom of the heel to the top of the longest toe, as illustrated in points A and B on the diagram. It is necessary to measure in three-digit millimeters (for example: 292mm)
Step 3: Measure the distance spanning the ball of the foot at its widest point, as illustrated in points C and D on the diagram, using two or three digit millimeter measurements depending on the size of your foot.
Step 4: Repeat the above steps for your other foot and compare the measurements. Find the longer of the two length measurements between your right and left feet, as well as the wider of the two width measurements.
Step 5: Use the longest length measurement and the widest width measurement in three-digit millimeters to reference the chart and find the appropriate size.
