Shoe sizes explained

  • In the United States, you can count the shoe size using the equation:

    shoe size = 3 × foot length [in] - 22

    for males, and

    shoe size = 3 × foot length [in] - 21

    for females.

  • In the European sizing system, the size is expressed in Paris points, which are equal to 2/3 centimeter.

    Shoe size [Paris points] = 3/2 × foot length [cm] + 2

How to convert US shoe size to EU

First, determine if the US size is male or female. Now the simplest way to convert the size step by step is:
