Let's take a look
Is the method of choosing shoes by foot type reliable?
The most commonly seen classification of foot types on the Internet divides foot types into "Egyptian feet", "Greek feet", "Roman feet" and "square feet" according to the relative position between the toes.
This simple classification helps to choose the shape of the toe.
For example, "Egyptian foot" is suitable for slanted toe shoes, "Roman foot" and "square foot" are suitable for square toe shoes, and "Greek foot" is suitable for round toe shoes.
But when choosing shoes, you also have to balance comfort and safety.
It has been suggested that the Greek foot is the most beautiful foot type, and it is said that people with this feature usually have slender limbs and more beautiful women.
However, although the "Greek foot" does produce some beautiful women, other foot types can still produce beautiful women, and the appearance has nothing to do with the foot shape.
Moreover, the "Greek foot" is a common anterior foot abnormality, which can lead to a variety of injuries such as back pain, low back pain, pelvic irregularities, etc., because the two-point support formed by the second toe and heel is far less stable than the triangle formed by the first and fifth toes and heels.
What other foot types are there?
In addition to the above classification of foot types according to the relative position of the toes, there are also simple classifications according to the arch of the foot:

In addition, some studies have also studied the use of the ratio of foot width to foot length to divide the foot type into narrow long type, intermediate type, and short width type. However, most of these foot type studies focus on relatively simple indicators such as foot length and foot width.
The foot is a varied three-dimensional shape, and changes in any one part should be taken into account when typing the foot.

Finally, the male foot type in China is divided into flat long type (ll type), slender short type (s type), and wide and strong type (wh type).
Female foot types are divided into wide and large (lw type), narrow flat type (nl type), and short and strong type (sh type).

Fully understand your foot type to find the right shoes for you.
Why do different foot shapes form?
There are many reasons that affect the shape and size of a foot, which can be summarized as biological and environmental factors.
Biological factors
1. Racial differences
Under the same foot length, German children's feet are slender, while Brazilian children's forefoots are narrow and his heels are wide. Racial differences may be caused by the long-term accumulation of genetic factors and living habits.
2. Gender differences
For example, a study of Japanese foot types found that under the same foot length, men's feet are wider and the arches are higher; while women's thumb valgus is significantly greater than that of men.
3. Age difference
The shape of people's feet is not static, but changes with age.
Babies' feet are flat, thick and very soft, and as they age, they gradually become ossified and hardened, become longer and wider, and the transverse arch is more pronounced. As an adult, feet are still malleable. Compared to younger people, older people's feet become longer, wider, and the arches are lower and flatter.
environmental factors
1. Wear shoes
The study found that compared with long-term shoe wearers in the same area, the spacing between the five toes of habitual barefoot people was significantly increased.
2, Region
A study of the foot shape of people in different parts of mainland China found that the foot shape of people in East China and Southwest China is fatter, and the foot shape of people in Northwest China is thinner.
3. Weight
Body weight is applied to the foot in the form of pressure, which may alter the distribution of soft tissues in the foot, thus affecting foot width, height, and circumference.
How do I choose the right shoes for me?
In addition to choosing shoes based on the relative position of the toes, the arch of the foot is also a factor that needs to be considered:
Most shoes on the market are designed according to the normal foot, so the normal arch can be selected from a wide range.
The high arch instep is high, it is easy to be oppressed by the upper, because the arc of the arch is too large, the impact between the foot and the ground during movement is very large, and it is easy to be injured. Lace-up shoes or comfortable mesh sneakers, stretch shoes, shock-absorbing shoes are preferred.
Flat arch is preferred to choose lace-up sneakers, the sole has arch pads, the heel is slightly stiffer, and the sole heel and bow waist are slightly narrower. When choosing leather shoes, try to avoid materials that are too soft and avoid shallow shoes. It should be noted that severe flat feet are not something that can be solved by a pair of shoes, and should be corrected in time.
In addition, split-toe sneakers, flip-flops, pointed shoes, ballet flat shoes, wedge-heeled effuser shoes, etc. are not conducive to foot activities and are not recommended to wear for a long time.
How do special people choose shoes?
When a runner chooses running shoes, he also chooses different running shoes by combining the arch type and the foot flip type:

Children and adolescents need to meet the normal growth and development of the foot and the amount of activity:
1, the toe of the shoe material to have a certain strength and toughness;
2. Easy to bend the outsole structure to ensure good bending function of the metatarsal toe;
3. Pay attention to the functional design of ankle protection;
4. The area of the sole of the forefoot is larger;
5. The non-slip design of the sole is in place.

Pregnant women's shoes should protect the ankle and heels, heel height of 2 to 3 cm low heel shoes or wedge shoes are appropriate, the sole should have non-slip lines, soft and comfortable, easy to wear and take off.
The shoes of the elderly should be selected:
1. The toe is relatively wide;
2, the upper should be soft, elastic and breathable;
3, the sole can not be too hard nor too soft, there is enough arch support;
4. The non-slip design of the sole is reasonable, and shoes with shoelaces should be avoided.
