Five Categories Of Shoes Design Knowledge

Shoes are indispensable daily necessities for people. With the development of human society, they have developed from the original protection function to the consumer goods of specific circumstances.

As a designer, it is the duty to enable people to enjoy the functional convenience brought by shoes and boots in different environments. This requires that the factors that affect the comfort of footwear products scientifically and reasonably are:

One, shoe last design for shoes.

The design of the last is based on the data of every part of the foot, and is the first one from the angle of footwear design.

The quality of the last type design directly affects the beauty and comfort of the shoes.

The 1. foot has four arches, that is, the front and rear horizontal arch, the inside and outside longitudinal bow.

When the foot is in motion, the four arches play the role of spring to slow down the ground counterforce.

When designing the last shape, if the front palm is too large, the shoe worn over this long time will cause damage to the anterior pverse arch ligament, lose elasticity and cause it to sag, then cause the pverse arch and the longitudinal arch to collapse and form a flat foot.

Flat feet are easy for patients to suffer from prolonged exercise and standing.

When designing the front palm crown, it is necessary to design the front and back stilts based on the human foot.

The front stilts are based on the natural stilts of the feet. The height of the front stilts of adults is generally controlled at 15-18.

The higher the rear stilts, the smaller the crown of the forehand, the smaller the front stilts, so that the area of the front palm can be ensured, so that the wearing will not be sprained.

The 2. metatarsophalangeal joint is one of the main parts of human body weight and labor load. It is also the key part of bending when walking. Whether the size of the last metatarsus and the physical arrangement are reasonable will affect the wearing comfort and the service life of the shoes.

The plantar circumference is large and the feet move in the shoes.

The rear stilt height is generally suitable for 20-40 old n.

Two, the sample design is a part of pforming the design into physical objects based on the rule of feet, the structure and function of the lower limbs, the material and the process. Through the help design, the design can smoothly pition to the product processing stage, so as to produce the products that conform to the design.

1. when designing full shoes, control the front face length of the shoe on the last surface - the mouth door position control point, because when the human body squats or the foot is bent, the upper part of the foot will be thickened.

The front face usually does not exceed the mouth door position, so as to facilitate the foot movement and prevent the tongue or shoe ears from grinding feet and knocking feet.

2. for the shoes with short front face, the rear part of the middle waist should be increased with the design of the feet, such as strips or small bags, and the design of the foot strap, so that wearer can walk without difficulty.

Often used in women's sandals design, the front narrow strip or short front support, walking without lifting feet, dragging the heel, it is very laborious, at this time should increase the design of feet at the back.

3. after the middle of the seam, except the high waist and tube boots, all the short shoes should control the height of the seam.

In particular, leather shoes, leather shoes because of the main heels, too high after the gang to cause grinding feet, card feet.

Too low for shoes.

Its height is controlled on the heel bone along the point, the scope should not be too large, and the reasonable size should be set according to experience and technological method.

4., the outer ankle height of the back Gang is designed in the design of the general short shoes, and the contour should be controlled after delineation. The theoretical basis is the high ankles inside and outside the feet.

The height of the lower edge of the ankle bone is derived from the rule of foot type. It can only be lower than this value and not high.

Otherwise, the ankle will be damaged by grinding the ankle bone.

And note that the internal and external ankles are different in height. The medial malleolus is higher than the lateral malleolus. When designing, it can be considered that the medial arm is better than the outer arm 2-3mm.

The 5. door door position control is located in the bending part of the instep exercise, because the deep and narrow door design is easy to tear and wear out.

6. little toe control point, broken band position or sandal band design at the end of the little toe, if not properly controlled, will cause the small toe to be exposed to collision and exposure. Some women's little toes are often drilled from the gap of the sandals, and the little toe is vulnerable to external injury and uncomfortable.

7. heel control points generally control the position of the two upright posts after the sandals, so as to improve the carrying ability of the upper to the heel.

Three. The influence of bottom parts design on comfort. The design of bottom parts includes soles, heels, main heels, inner Baotou, insole and so on.

1. the design of the sole should not be too heavy.

For winter wear shoes, the design of a slightly thicker bottom is beneficial to isolate the ground air conditioner and maintain the normal temperature of the feet.

Too thick, so that the feet feel bad on the ground, easy to make the center of gravity biased, the phenomenon of sprained feet.

The design of bottom pattern affects the skid resistance of shoes.

The design of bottom pattern should resist lateral and longitudinal slip.

The skid resistance is good, and the friction between sole and ground is increased when walking. People can walk freely with the help of the ground reaction force.

On the contrary, people are difficult to walk and are easily injured by their feet and body.

The special structure design makes the air in the shoes effectively change in the movement and improves the comfort.

2. a reasonable design can make the weight of the human body more reasonably distributed on the supporting points of every part of the foot, enhance the stability of the human body and improve the elasticity of the arch.

The height, size and shape of heels affect the comfort of shoes.

The height of the heel depends on the height of the last step. When designing or selecting, the attention should be paid to the consistency between the two.

The lower edge of the calcaneus is the main force point of the center of gravity of the human body. It is located at the center of the heel of the foot of the human body. Therefore, the vertical force between the lower surface of the calcaneus and the ground must be penetrated through the base, the heel and the heel.

The size of the seat surface affects the fastness of shoe heel assembly.

It has large contact area with the seat surface and large contact area with the heel part of the sole. It is not easy to shake when worn. The size of the heel affects the area and plays a role of stabilizing the center of gravity.

At the bottom of the small heel shape, it is not easy for people to master the balance in movement. The width of the heel without thickness is very light and elegant. If the assembly position is on the back, the heel tends to lean backward when walking, so that people feel a sense of forward setback.

3. during the design of Baotou, the length should not exceed the bending part of the foot. Otherwise, the bending of the foot is limited, and there is a hidden danger of cards and grinding feet.

4. due to the physiological function of the feet, the distribution of sweat glands on human feet is not balanced.

The density of the foot and metatarsophalangeal joints is the largest, and the heel and instep should be less. Therefore, we should pay attention to the design of the insole, insole and inner lining of the front palm.

The interior design increases softness and breathability.

For the middle sole design of the sneakers, elastic materials are used to ease the impact of the foot and the ground.

Four, the choice of materials for comfort, the selection of shoes is not only the appearance, but also to a large extent, considering the hygienic properties of shoes.

Whether the shoe is comfortable or not is related to the microclimate in the shoe.

The natural grain leather and cotton textiles in the upper material have excellent hygienic properties. Because of the good permeability, moisture permeability and moisture absorption of the material, there are prerequisites for not stuffing feet and not covering their feet.

At present, the synthetic leather and artificial leather developed by our country are far inferior to natural leather in terms of hygienic properties. Therefore, when designing, we should choose suitable materials according to the style, wearing conditions and environment, so as to enhance the comfort of shoes.

Redecorated leather and two layers of leather are leather shoes, but their surface is covered with finishing materials. The pores of natural leather are blocked, so their permeability and moisture permeability are greatly reduced.

The upper material of the upper fabric should be selected for materials with good hygiene and comfort, such as breathability, moisture absorption, lightness, softness, sterilization and deodorization.

The superior material of shoe upper should be used in combination with materials such as lining, inner bottom, inner Baotou, adhesive and other materials, so as to give full play to its superior performance.

Rico, the shoe material is closest to the feet, and the feet give steam and sweat. If Rico itself does not have breathable and moisture absorption functions, the hygienic properties of the fabrics will not be realized.

Good quality shoe interior materials should be hygroscopic, breathable, with good dimensional stability, flexural flexibility, etc., in order to meet the requirements of use, will also give the foot a comfortable bottom environment.

The properties of sole materials greatly affect the comfort of wearing.

For shoes wear occasions and the purpose of use.

For general shoes, the sole design should be light in weight and moderate in hardness.

Hardness is too low, no stiffness, feet easily pulled; too high, walking feet, can not bend with the feet, two cases are easy to cause foot fatigue.

Five. The influence of the production process on the comfort of the shoes. The influence of the production process on the shoes is due to improper or improper process operation.

Improper or improper process operation will affect the appearance, wearing life and wearing comfort of shoes.
