Basic Knowledge Of Leather Shoes Design

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 responsibility of people to enjoy the functional convenience of shoes and boots in different environments. This requires that there are five main factors that affect the comfort of footwear products scientifically and reasonably: last type design, sample design, bottom part design, material selection and process design.

First, the influence of last design on the comfort of 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, sample design.

Sample design is a link that pforms the design into physical objects based on the foot type rule, lower limb physiological structure and movement function, material and technology. Through the help design, the design can smoothly pition to the process stage of product processing, so as to produce the product that accords with 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.
