How to know your shoe size

To know the shoe size, you need to measure the length and circumference of your feet.

1, foot length measurement

Foot length refers to the horizontal straight line distance between the apex of the longest toe and the heel protrusion. The specific method of measuring the foot length is: take a piece of white paper and a pen, step on the white paper, draw the periphery of the foot along the shape of the foot (90 degrees perpendicular to the paper) with the pen, or mark the longest front end and back end of the foot respectively; According to the foot map drawn, measure the longest length from toe to heel, which is the foot length. Be careful not to measure your feet directly, there will be a big error in direct measurement.

2. Foot circumference measurement

Foot circumference refers to the width of the foot, that is, the horizontal straight line distance from the root of thumb to the root of tail toe. The specific method of measuring the foot circumference is: just like measuring the foot length, lightly step on the paper with a pen and paper to trace the outline shape, and then measure the widest width of the foot map.

Generally speaking, the size is judged mainly by the length of the foot. However, it should be noted that if the foot width exceeds the normal value, or the instep is high, it will affect the size, so it is necessary to wear shoes of one size or even two.

3, measuring time

It is suggested that it is best to measure the foot size in the afternoon, because the foot will expand slightly in the afternoon, and the determined size is the most comfortable to wear at this time.

Note: people's left and right feet are basically symmetrical, but there must be subtle differences, so choose a bigger one when measuring.

4. Compare with shoe size table

According to the length and circumference of feet, find the shoe size that suits you according to the standard shoe size comparison table.

Extended data:

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, generally including length and width. Length refers to the length of the wearer's foot or the length of the manufacturer's shoe last. Even in the same country/region, different people and shoes with different uses, such as children and sports shoes, have different definitions of shoe sizes.

The Mondopoint shoe size system recommended by ISO standard ISO 9407 is based on the width and average length of the foot, with millimeters as the basic unit.

In the late 1960s, Chinese mainland formulated the "China Shoe Size" based on the national foot length measurement, with the length range of 1 (1 cm) and the width of 1 (narrowest) -5 (widest).

1998, the government issued the China people's standard GB/T3294- 1998, which is called "new shoe size" based on the Mongolian multi-point system and in millimeters. The shoe size in centimeters used to be called "old shoe size" from now on.

2 1 century shoes in Chinese mainland market 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+10)/2. (New shoe size needs to be converted into units)
