Interpretation Of The Quality Of Leather Shoes

July 13th leather shoes are made of natural leather, synthetic leather or synthetic leather as the main raw materials and other synthetic materials.

Key indicators

1. shoe number.

According to the national leather shoes standards, the shoes and shoes numbers should comply with the requirements of GB/T3293.1-1998.

At present, leather shoes sold in the market can match the index in shoe numbers, except for shoes with special foot problems.

2. shoe last size.

When designing a sample, it is necessary to properly handle the relationship between the last shape and the sample line. The position of the shoe after the change of line on various shoe last shoes is in harmony with the foot type and the last type.

3. shoe upper material.

The quality of the shoe material determines the cost of the finished shoe and the factory price and the marketing situation.

Most of the finished shoes are high-end brand, and they will study leather material and shoes making.

4. sensory quality.

Among them, the overall appearance, facade, main heel and Baotou, heel and Zi Kou 5 items are the main items, and the 5 items of suture, folding edge, outsole, fittings and dimensions are minor items.

5. peel strength.

When the surface is sheepskin and artificial material, the front end thickness of the outsole is less than 3mm; the strength of the outsole width less than 40mm at the 20mm breakpoint from the outsole is greater than 40N/cm.

6. folding resistance.

At present, the shoe sole materials in the market basically meet the requirements, and there are fewer cracks, cracks, cracks, or glue opening on the bottom.

The main reasons for the failure are shoe sole materials or too many stuffing materials.

7. wear resistance of the outsole.

The wear-resisting performance of sole depends on the properties of the material itself. The wear resistance of qualified products soles is close to rectangle and less than 14.0mm, and different people wear uneven strength at the bottom of their feet, causing some shoes to tilt towards a certain side, causing bad habits for long-term wear. Therefore, the wear resistance of the shoe bottom materials is more stringent.

8. the strength of heel.

The height of heel and the area of the heel determine the compressive strength of the back of the shoe. During walking, the heel may shake or clip in some gaps. If the heel binding force is not enough, it will easily lead to ankle sprain. Therefore, the pursuit of the beauty of the heel requires higher heel adhesion.

Shopping guide

1. leather.

There are two kinds of leather shoes: smooth leather and reverse leather.

Smooth leather shoes with good quality, even and smooth grain size, smooth and meticulous, no wrinkles and scars, uniform brightness and color, bright and bright colors, no shades and shades.

Press the skin with your fingers. The wrinkles are uniform and small. When the fingers are released, the fine lines disappear immediately. The touch feels soft, lubricated, elastic and rigid, and the thickness of the leather is uniform and moderate.

The reverse leather shoes with good quality are soft, uniform and uniform in color. They have no thick long fiber and oil stains. They have no obvious wrinkles and scars. They feel the same as smooth leather shoes.

2. sole.

Leather shoes have two types of leather and leather.

The leather shoes with good quality are smooth, smooth and uniform in color. There are no spots, stains and scars. They are thick and thin.

The soles are flexible, plump, tensile strength and wear resistance.

The quality of the colloidal sole is smooth and uniform, and the patterns are neat. Each edge should be bright and complete.

From the side, the cut surface is uniform and meticulous without impurities, no particle size, no thickness and uneven phenomenon. Touch with hands should have better toughness and elasticity.

If you are glued with leather shoes, check that the bottom edges are tight and smooth, and there is no space and glue.

3. breathability.

Leather leather has the worst permeability in synthetic leather.

Natural leather shoes generally have better air permeability, especially pig leather, because porcine skin pores are several times thicker than cattle skin pores, pores are much larger and sweat is easier to discharge, but leather is not as good as cowhide.
