Steps to check VANS shoe size:
Step 1: Prepare a piece of paper and place your foot on that piece of paper.
Step 2: Draw the heel and toe on the paper.
Step 3: Draw a line from the tip of the heel to the tip of the longest toe as shown (note: use the longest toe because some people have long big toes, some people have long middle fingers, etc.)
Step 4: Measure the length of the straight line and compare it with the Cm section of the size table.
