Excuse me, how to calculate the size of shoes?

The calculation method of shoe size is that the foot length times 2 minus 10 equals the shoe size. For example, a foot length of 25 cm corresponds to 25 times 2 minus 10 equals 40 yards, so the internal length of 44 yards is the sum of 44 plus 10 and divided by 2 equals 27 cm.

Shoe size, also known as shoe size, is a standard unit system, which is used to measure the shape of people's feet in order to match shoes. The shoe sizes adopted by countries all over the world are not consistent. Even in the same country or region, the shoe sizes of different people and different uses are different.

According to the size comparison table of China, size 38 is 24 cm, size 39 is 24.5 cm, size 37 is 23.5 cm, size 40 is 25 cm, size 4/kloc-0 is 25.5 cm, size 42 is 26 cm and size 43 is 26.5 cm. There may be errors in the actual work of the shoe field, and the shoes are generally 0.5 cm smaller.

Male adults with average height 1.85 meters generally wear shoes with standard shoe size of 270 (commonly known as size 44). There is a relative proportional relationship between height and foot length: 7: 1. To calculate height according to foot length, we should also consider regional factors, such as heredity, race and nutrition. And there are exceptions (such as short feet and tall feet).
