1. The quality of the shoe material includes the upper part of the upper and the shoe, and the authenticity of the leather should be discerned.
(1) Natural skin characteristics
1, the leather smell is thicker, thicker, generally greater than 1.0m / m, resistant to torture.
2, covered with a lot of fine pores, good ventilation performance.
3, the dermis has obvious stratification, showing a transitional state.
4, good softness, luster, longitude, not easy to deform after molding.
2. Check the adhesion of the upper suture and the bottom, and identify the quality of the processing.
See if there are broken wires and whether the upper sutures are neat and tidy. In particular, the bonding part of the adhesive leather sole should be bonded flat and without gully, and the glue oozing and opening depth and width should not be more than 1mm and can not exceed 2 places. Casual men's shoes line requirements: the distance between the car line and the leather side is generally set to 1-1.5mm. The margin is even, the line is even, no jumper and disconnection.
3. Touch the inner cavity of the shoe to see if there is any unevenness in the shoe and the inner sole.
Anything that can touch the feet should not be uneven, otherwise the feet will blister. There must be an insole in the shoe, which is designed to keep the inside of the shoe clean, cover the uneven nails on the inner bottom, and improve the touch of the foot.
4. See if the front and back gangs are qualified when climbing. Ask the front and back gangs to align with the middle line respectively.
5. Press the inner bottom of the waist to see if it is hard.
The inner sole of the shoe is the torso and skeleton of the shoe, and the inner sole is pressed hard, so that the silk does not move as well. The skeleton and the trunk are not stiff, and the shoes are inevitably deformed and damaged.
6. Place the shoes flat on a horizontal table or glass plate to see if the shoes are stable.
When the shoes are placed on the table, they should stop shaking right and left immediately.
7. Use the middle fingertip to insert under the front sole to see if the front height is suitable.
When the apex of the toe is just enough for the thickness of the middle finger, it indicates that the front of the toe is just right. When the front of the toe is too large, the stability is lowered; when the front is too small, the shoe is worn quickly, the shoe is easily deformed, and the foot is prone to fatigue. Use a ruler to measure whether the height of the shoe is parallel. Whether the middle gang is parallel or not, the heel is parallel.
8. Put the shoes on the table and check whether they are correct from the front and rear directions.
First, from the toe of the shoe to the back, to see the size of the inner and outer edges of the sole from the top of the table, the difference should be small, in order to maintain a balanced balance. Then, from the heel of the shoe, look up to see if the heel of the shoe is up and down, so that it is not inclined to the inside or the outside.
IX. Check the symmetry of the upper part and whether the contour of the upper is deformed
Taking the straight line between the toe and the midpoint of the heel as the axis of symmetry, it is better to see whether the components on the upper are symmetrical, and the inner and outer sides are symmetric with each other and not moved forward and backward. The contour of the shoe opening should be hugged in the shoe, smooth and smooth; the twisted into the lotus leaf shape is the inferior shoe.
X. Understand the performance of the outsole of the shoes, choose the appropriate outsole
The following is the material difference between the soles of the shoes: the casual shoes are widely used in the composite rubber outsole.
1, leather sole:
The leather sole is a sole that can breathe automatically and breathe the foot. It has good air permeability and no loose feet. It can automatically release the absorbed sweat to keep the feet dry. The leather sole is mainly made of cowhide and the price is higher. The utility model has the advantages of easy setting, invariable type, fit, and good elasticity, can reduce impact without fatigue, ventilate, absorb moisture, etc., and is easy to process, and the shape is easy to display aesthetics. Hard texture is not easy to be pierced, but it is easy to warp or rot after being soaked in water and oil. Its main features: A, has a good thermal insulation to ensure the proper temperature of the foot in the shoe B, light weight, the weight per square centimeter is 0.95 ~ 1.05 grams, just the same as the density of water. It is waterproof and releases moisture when the shoes are no longer wet, ensuring that the shoes are in a comfortable state. C, unique three-dimensional fiber structure, the sole does not break when bent at 180 degrees. It can quickly adapt to the shape of the foot, can effectively support the impact of the ground, and protect the foot more effectively than the sole of other materials of the same thickness.
2. Rubber sole (RB):
RB is an abbreviation for English rubber (rubber); hot compression molding, divided into natural rubber and recycled rubber. It is heavy and oil-resistant. When molding the bottom, it must be ground on the bonding surface. It is easy to shorten when heated, and the color is inconsistent.
Advantages: good wear resistance, non-slip, elastic, not easy to break, good softness, good ductility, stable shrinkage, good hardness, good flexibility and waterproof.
Disadvantages: heavier, easy to spit (it is a quality problem), not easy to corrode (environmental problems); not hard, easy to be punctured; breathable, hygroscopic, not afraid of oil soaking, not suitable for contact with oil at gas stations Place to wear.
A rubber foaming weight is lighter than rubber sole, with rubbery taste. When pressed with fingers, the surface rebound is more obvious than the general sole, and the wear resistance is poor.
Eleven, is the shoe molding qualified?
Hold the left and right feet in your hand and see if the toe is the same. Whether the height of the toe to the eyelet is the same. Is the height of the heel of the shoe the same?
