Nike children's shoes 8c are equivalent to 7.5K of Adidas babies.

shoe size, also called shoe size, is a standard unit system used to measure the shape of human feet in order to match shoes. In 213, the shoe sizes adopted by countries all over the world were not consistent, but generally included two measures: length and width. Even in the same country/region, different people and different uses of shoes, such as children and sports shoes, have different definitions of shoe sizes. In the late 196s, based on the national measurement of foot length, Chinese mainland formulated China shoe sizes with a length interval of No.1 (1cm) and a width of 1 (narrowest) -5 (widest).

Different shoe sizes

Classification

Different shoe sizes include: British size, American size, Japanese size, etc.

Europe

The shoe sizes of continental European countries such as France and Germany are generally calculated as follows, and the unit is cm:

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.

north America

shoe sizes in the United States and Canada are measured by 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 women's shoe size, which is determined by the Footwear Industries of America.

Hong Kong

American and European shoe sizes are commonly used in Hong Kong. Generally, Hong Kong men wear shoes of size 42-48 (European size), while women wear shoes of size 36-4 (European size). Generally speaking, the length of the foot determines the shoe size, but if the foot version is wider (more than 9.5cm) or thicker, it is necessary to add half a yard. For example, if the feet are 29.5-3. cm long, you should wear size 46 (European size) shoes. If your feet are 27.5cm long, you should wear size 43 (European size) shoes.

Men's shoes

In the late 196s, Chinese mainland formulated the "China Shoes Size" on the basis of national foot length measurement, with the length interval of No.1 (1cm) and the width of 1 (narrowest) -5 (widest).

In 1998, the government issued the Chinese national standard GB/T3294-1998, which is based on the Mondopoint system and takes millimeters as the unit, and is called "new shoe size". Previously, shoe sizes in centimeters were called "old shoe sizes" from now on.

All shoes on the market in Chinese mainland in the 21st century are required to be marked with new shoe sizes.

the conversion formula of old and new shoe sizes is: new shoe size = (old shoe size +1)/2. (New shoe size needs to be converted into units)

Example:

If the old shoe size is 4 yards

, the new shoe size = (4+1)/2

= 5/2

= 25 cm

= 25 mm

The new shoe size is 25 yards
