European shoe sizes often consist only of whole numbers. This is because the sizes are based on centimeters, and because a centimeter is smaller than an inch, the size will by definition be more precise. Originally, the method to calculate EU shoe sizes was developed in France several hundred years ago and goes as follows:
EU shoe size = (Foot length in cm + 1.5) x 1.5
So if your foot is, for example, 24 centimeters long, the calculation would be: (24 + 1.5) x 1.5 = 38.25. In this case, you would round to the nearest whole size, in this case, 38.
Note: Although this formula is often used, the result may vary based on the specific shoe size chart used by different brands or countries. It is always advisable to consult the specific manufacturer's size chart for the most accurate conversion.
