How to calculate the size of feet

Calculation method of foot length and shoe size

Calculation method of shoe size (code): shoe size = foot length ×2- 10.

Calculation method of foot length (cm): foot length = (shoe size+10)÷2.

(foot length unit: cm? Shoe size unit: yards)

For example, your feet are 25.0cm long. How many yards is 25.0? How to convert it?

25.0cm× 2- 10 = 40 yards (25.0)?

Correct shoe selection strategy:

The first trick: don't buy a pair of shoes that don't fit the size just because they are discounted at the end of the season or really like them. Don't think that shoes that are too small can get bigger and bigger, but you should know that the degree of support is limited. Temporary inspection of the foot surface may cause a series of diseases such as corns, blisters, foot pain, leg pain and back pain.

The second trick: you should know that your feet will swell with heat and shrink with the seasons. If you buy shoes that are discounted in summer in winter, try on the right size, which may be slightly smaller than those in summer.

The third measure: Ten toes can move freely in the shoes, which is an ideal size. At the same time, there should be comfortable filling and moderate internal space. Moreover, the radian of the sole of the foot and the depression of the foot are very close to the foot, and the ankle bones and toes can't touch the shoes. The upper surface of the sole of the heel should be well attached to the heel, and it will not slide left and right when walking.

The fourth trick: If you like a pair of shoes, but the material is not good, then don't buy them. Within the scope of economic conditions, it is best to choose all leather shoes with smooth leather surface, no sewing lines inside and leather soles. Because leather has good air permeability, sweat absorption function and elasticity, and will not suppress sweat, it is very comfortable to wear.

The fifth measure: Generally speaking, the higher the heel, the wider the trouser legs; The shorter the heel, the narrower the trouser legs, which makes people more comfortable to wear. So when trying on low-heeled or flat shoes, you can narrow the trouser legs with a small clip to see the effect.
