the CM in the Nike men's shoe size comparison table indicates the shoe length.

foot length measurement: the horizontal straight line distance between the vertex of the longest toe and the heel protrusion. Be careful not to measure your feet directly, there will be great errors in direct measurement. The measurement method is as follows:

Tools: A4 paper, pen and ruler

1. First, put a piece of A4 paper on the ground, remove socks with both feet, stand naturally, and put one foot on A4 paper;

2. Draw the outline of the foot with a pen vertically close to the foot, but without pressing the foot;

3. Use a ruler to measure the longest and widest distance between two feet; The longest distance is the net foot length, which is used to refer to the size of shoes;

4. The widest width is the clear foot width, which can be used as a reference for the width of the shoe type. If the clear foot width is too large, the size of the clear foot width should be selected, and it is usually appropriate to select half the size according to the clear foot length.

1. Europe

The shoe sizes of continental European countries such as France and Germany are generally calculated as follows, in centimeters:

Shoe size = 1.5* last length = 1.5* (foot length+2)

However, the specific size may be slightly different due to different characteristics of last.

2. North America

Shoe sizes in the United States and Canada are measured in inches:

Men's shoe size = 3* Shoe last length -22

Women's shoe size (common) = 3* Shoe last length -2.5

In addition, there is a relatively rare shoe size for women, which is made by Footwear Association of America (Footwear).
