How to calculate the shoe size

• Pull the linen out of the shoes and measure its length.
• If the insole is not removed, wear a sock of required thicknes, stand on a piece of paper and circle the foot with a pencil or pen.
  
• Take the ruler and measure the distance from one extreme point to another. Do the same with the other leg. Take as its basis the biggest number.
  
• Round the result and find your size in the shoe size chart
