1. The quality of shoe materials includes the upper and the insole, so it is necessary to distinguish the authenticity of leather.
Natural leather is genuine leather with pores. When it is difficult to see clearly with your eyes, you can press the leather surface with your thumb to see if there are fine dermatoglyphics next to your thumb. There are fine lines, and the fine lines disappear after letting go. The natural leather with good elasticity on the surface of leather shoes is good, and the natural leather with large wrinkles and deep wrinkles is poor leather. If there are no fine lines, most of them are not natural leather, including two layers of shaved skin.
Another notable feature of natural leather is that the leather surface has defects. Generally, the upper of natural leather will have a few slight defects in inconspicuous places such as the inside of the shoe, such as uneven skin texture, bright furuncle, lice furuncle and so on. The cross section of natural leather has three layers with different densities: the epidermis is very thin and elastic, with a dense dermis in the middle, and the meat surface below is a loose fiber layer with no obvious boundaries between layers.
The lining of leather shoes is a reinforcing material used to prevent stretching deformation and improve the touch of the foot. It is required that the materials in the shoes have delicate feel, good air permeability, excellent moisture absorption and perspiration performance and no fading. Middle and high-grade leather shoes are made of natural leather and cotton cloth. If the upper is natural leather and the shoes are artificial leather, they can only be regarded as middle and low-grade shoes. Most consumers ignore the selection and identification of materials in shoes, which is wrong.
2. Check the sewing thread of the upper and the glue seam of the sole to determine the processing quality.
See if there are any broken lines and whether the upper stitches are neat and standardized. In particular, the upper and lower bonding parts of bonded leather shoes should be bonded smoothly, without grooves and ridges, and without signs of virtual seams and glue opening.
3. Touch the inner cavity of the shoe with your hand to see if there are irregularities in the shoe and insole.
Wherever you can touch your feet, don't be uneven, or your feet will blister. There must be an insole in the shoes. The insole is designed to keep the shoes clean, cover the uneven nail holes on the insole and improve the touch of the feet.
4. Pinch the heel of the vamp by hand to see if it is stiff and elastic.
It is required that there should be no groove marks on the stiff part of the heel, and the elasticity under the ankle should be good, and it should not be too hard, otherwise it will damage the ankle.
5. Press the insole on the waist to see if it is hard or not.
The insole of a shoe is the trunk and skeleton of the shoe. It is best to press the insole hard and don't move. If the bones and trunk are not stiff, shoes will inevitably deform and damage the foot shape.
6. Feel free to lay your shoes flat on the table or glass plate to see if they are stable.
When the shoes are placed on the table, they should stop shaking from side to side immediately.
7. Insert the tip of the middle finger under the toe sole to see if the toe height is appropriate.
When the toe of the toe is just enough for the belly thickness of the middle finger, it means that the toe of the toe is just right. When the toe cap is too large, the stability decreases; The front stilts are too long, the soles wear quickly, the shoes are easy to deform and the feet are easy to fatigue.
8. Hold the shoes by hand to see if the sole and heel contact smoothly.
Place the sole and heel gently on one side of the table (or counter), with the side of the shoe facing upward, and check the contact parts of the sole. It is better for the sole (the widest part of the sole) and the whole heel plane to contact the side of the table. Otherwise, the shoes will deform easily and the heels will fall off.
9. Put the shoes flat on the table and check whether they are correct from the front and back directions.
From toe to back, look at the size of the inner and outer edges of the sole inclined from the desktop. There shouldn't be much difference, so it's better to keep a balance. Then from the heel to the front, check whether the heel is vertical up and down to avoid leaning inward or outward.
10. Stand on the outside of the heel of shallow shoes with your index finger and check the height of the upper at the outside ankle.
The tip of the index finger touches the insole downwards, so that the index finger is close to the upper part of the lateral ankle, and whether the height of the second knuckle line of the index finger is consistent with the upper part of the lateral ankle. Generally, daily shoes, social etiquette shoes and fashion shoes should be slightly lower than the second knuckle line of the index finger. The upper openings of the back uppers of low-waist sports shoes and leisure shoes are all soft-mouth structures, and the height of the lateral ankle uppers can be slightly higher than the second knuckle line of the index finger.
1 1. Look at the vamp from top to bottom to see if the vamp components are symmetrical and the vamp outline is deformed.
Take the straight line from the toe of the shoe to the midpoint of the heel as the symmetry axis to see if all parts of the upper are symmetrical. It is best to keep internal and external symmetry and not to move back and forth. The contour line of the shoe mouth should be held to the inside of the shoe, and it is better to be smooth and round; Those twisted into lotus leaves are inferior shoes.
12. Understand the performance of shoe outsole and choose the appropriate outsole.
There are many kinds of outsoles of shoes, which can be divided into rubber soles, imitation leather soles and plastic soles according to the main raw materials. Their respective properties are: rubber soles are soft, elastic, non-slip, wear-resistant, heat-resistant and cold-resistant. It's just a little heavy.
Imitation leather shoes soles are light, crisp, wear-resistant and tortuous. But the elasticity is poor, not very slippery. Plastic sole has good wear resistance and elasticity. But the texture is hard and the heat and cold resistance are poor.
