How to use a test machine to identify the quality of leather shoes

Put the sole and heel lightly against the side of the table (or counter), so that the side of the shoe faces upward, and view the contact area of ​​the sole. It is better to contact the soles of the shoe (width of the sole) and the entire heel plane with the side of the table. Otherwise, the shoes will easily deform and lose the heel. Place the shoes flat on the table, fromCheck whether the shoe material is correct in both front and back; the quality of the shoe material includes the upper and inside the shoe, and the authenticity of the leather should be distinguished. Natural leather is, which is usually difficult to see clearly with the eyes. When the thumb is used to press the leather surface with your thumb to see if there is any fine one next to the thumb.The leather pattern has fine lines, the fine lines disappear after letting go of the hand, and the leather shoes have a plump and elastic surface, which is better natural leather. The leather with larger and deeper wrinkles is the natural leather with poor leather. If there are no small patterns, most of them are not natural leather, including the second-layer finishingAnother prominent feature of natural leather, film leather, is that there are flaws on the leather surface. Generally, natural leather uppers have a few slight flaws on the inside of the shoe and other inconspicuous places, such as uneven thickness of the leather pattern, bright boils, lice boils, etc. Cross section of natural leatherThere are three levels of sparse and denseness: the surface layer is very fine and flexible, with a dense layer in the middle, and a relatively loose layer of flesh-face fiber below, and there is no obvious demarcation between layers. In leather shoes, it is to prevent extension and deformation and improve the touch of the feet.Reinforced materials used. The materials in the shoe are required to have delicate touch, breathability, excellent moisture absorption and moisture removal, and color removal. The shoes of the mid-leather shoes are made of natural leather and cotton. If the upper is natural leather, the shoe is artificial substituteLe can only be considered a mid-to-low-end shoe. Most consumers ignore the selection and identification of materials in shoes, which is wrong. Looking down at the upper from top to bottom, check the symmetry of the upper parts and whether the outline of the shoe mouth is deformed. The straight line between the tip and the midpoint of the heel is the same as the line between the shoe tip and the heel.To measure the axis, see if the components on the upper are symmetrical. It is better to be symmetrical between the inside and the outside and not move forward and backward. The outline of the shoe mouth should be hugged toward the inside of the shoe. It is better to be smooth and round; the one that is twisted into a lotus leaf shape is inferior shoes. Understand the performance of the shoe's outsole and choose the appropriate outsole.There are many outsoles of shoes, which can be divided into rubber soles, imitation leather soles, plastic soles, etc. According to the main raw materials, their respective properties are: rubber soles have the characteristics of softness, good elasticity, anti-slip, wear resistance, good heat and cold resistance. It's just a little heavier texture. The imitation leather sole is lightIt is resistant to wear and twists. But it is less elastic and not very anti-slip. Plastic soles are wear-resistant and elastic. But the texture is hard and the heat and cold resistance is poor. Check the upper suture and upper sole bonding seams to identify the quality of processing and production to see if there are any broken threads.Is the upper suture neat and standard? Especially the joint area of ​​the upper soles of the adhesive leather shoes should be flat and without grooves, without any signs of debris and opening. Touch the inner cavity of the shoe with your hands to see if there are any unevenness inside and on the inner soles of the shoe. Wherever you can touch the feet, do notCan be uneven, otherwise your feet will blister. There must be insoles inside the shoes, which are designed to keep the inside clean, cover the uneven nail holes on the inner sole, and improve the touch of the feet. Pinch the heel of the upper and lower shoes with your hands to see if it is hard and elastic. Require a hard heelThere should be no traces of grooves and bumps. The elasticity below the ankle is good and cannot be too strong, otherwise it will damage the ankle. Press the inner sole on the waist to see if it is hard. First, look at the toe facing back, and see the size of the inner and outer edges of the sole from the tabletop. There should be no big difference to maintain balance and consistency.good. Then, facing forward from the heel of the shoe, check whether the heel of the shoe is vertical up and down, so as not to tilt the inside or outside. Use your index finger to erect on the outside of the back top of the shallow top, check the height of the upper part of the shoe upper. The index finger tips touch the inner sole of the shoe, so that the index finger is close to the outer ankle.The upper of the shoe depends on whether the second knuckle line of the index finger is consistent with the upper height of the outer ankle. Generally, daily shoes, social etiquette shoes, and fashion shoes are slightly lower than the second knuckle line of the index finger; the upper back upper mouth of the low-waisted sports shoes and casual shoes are both soft-mouthed, outsideThe ankle height can be slightly higher than the second knuckle line of the index finger. The inner sole of the shoe is the torso and skeleton of the shoe. Press it hard to keep it moving. If the skeleton and torso are not stiff, the shoes will inevitably deform and damage the shape of the feet. Place your shoes flat on a tabletop or glass plate, check whether the shoes are stable. When the shoes are placed on the table, stop shaking left and right immediately. Use the middle finger tip to insert the sole of the front pointed shoe to check whether the front squin height is appropriate. When the toe of the shoe tip is just enough to the thickness of the middle finger, it means that the front squin of the shoe tip is just right.When the front squinting of the shoe tip is too large, the stability decreases; if the front squinting is too small, the shoe will wear quickly, the shoe will easily deform, and the feet will easily become tired. Hold the shoes with your hands to see if the sole and heel are in contact smoothly.
Footwear complaints have always been at the forefront of all kinds of product complaints. How to do a good job in appraisal and protect the interests of consumers is our imperative responsibility. To identify the quality of a pair of leather shoes, you need to focus on both appearance and internal indicators. Intrinsic indicatorsThe physical and mechanical properties of instant shoes must be detected by instruments. For manufacturers, they must have professional testing machines to test the quality of leather shoes so that they can be responsible to the majority of consumers.
