Abstract

The utility model relates to the technical field of soles, in particular to a flexible damping sole, which comprises a small sole, a middle sole and a big sole, wherein a cavity and a damping body corresponding to the cavity are arranged at the heel of the big sole, and the damping body is just accommodated in the cavity; the bottom of the outsole is provided with a cutting line mark which can cut along the pattern path of the outsole. The arrangement of the cutting lines of the sole makes the sole more complete; the shock absorber arranged at the heel plays a certain shock absorbing role in the wearing process, and the wearing comfort of the shoe is improved. The utility model is suitable for shoes, casual shoes, light sports shoes and other articles.

Description

Damping sole of easily buckling

Technical Field

The utility model relates to a sole technical field, concretely relates to damping sole of easily buckling.

Background

Along with the acceleration of the pace of life and the improvement of health awareness of people, the requirement of people on the comfort of feet is also improved, the requirement on the comfort of the traditional leather shoes/leisure leather shoes as the choice of people in public business is higher and higher, and the leather shoes have the defect of being stiffer due to the structure.

The sole is an important component of the shoe and is a key part which most affects the wearing comfort of the shoe, and the softness and the shock absorption degree of the sole are key factors of the comfort of the sole.

Disclosure of Invention

The utility model provides a flexible damping sole to optimize the sole stiffness problem of the existing front-end shoes and leather shoes.

A flexible shock-absorbing sole is composed of a small sole, a middle sole and a big sole, wherein a cavity and a shock-absorbing body corresponding to the cavity are arranged at the heel of the big sole, and the shock-absorbing body is just accommodated in the cavity. The bottom of the outsole is provided with a cutting streak, and the depth of the streak is smaller than 1/2 of the thickness of the outsole.

Furthermore, bulges are distributed at the half sole of the small sole.

Furthermore, the bottom of the outsole is provided with an undersize, and the cutting lines are cut along the undersize pattern.

Furthermore, the bottom of the outsole is provided with a wavy bottom.

Furthermore, the shock absorber is high-elastic PU.

Furthermore, the half sole of insole is provided with high-elastic PU gasket.

Furthermore, at least one anti-slip strip is arranged at the heel of the outsole. The anti-slip stripes are formed by foaming together with the outsole.

Furthermore, the anti-slip stripes are made of glass fibers; during the production process, the glass fiber is placed at the bottommost layer of the mold, the outsole foaming material is placed on the glass fiber, and then the outsole foaming material and the glass fiber are foamed together.

Further, the small sole and the middle sole are formed by foaming EVA; the outsole is formed by rubber in one step.

Compared with the prior art, the utility model discloses a have following beneficial effect to do:

1. the utility model is formed by compounding a small sole, a middle sole and a big sole, and the three components all provide certain cushioning and shock absorption effects; the shock absorption body is arranged at the heel, so that the shock absorption and buffering functions of the whole shoe are further improved, and the shoe is more comfortable to wear; meanwhile, the shoes are easier to bend by cutting the marks on the half sole of the sole.

2. The half sole of the small sole is distributed with bulges; can massage the sole of the foot and can play a certain anti-skidding effect in the shoe.

3. The half sole department in insole is provided with high-elastic PU gasket, further promotes the bradyseism effect of sole, promotes the travelling comfort of dress.

4. The heel part is provided with anti-slip stripes formed by foaming glass fiber and the outsole together, the process is simple, and good anti-slip effect can be achieved on indoor smooth floor tiles or other smooth surfaces.

Drawings

Fig. 1 is an exploded view of a sole structure according to an embodiment of the present invention.

FIG. 2 is a schematic bottom view of a sole according to an embodiment of the present invention;

wherein: 1. a small bottom; 11. a protrusion; 2. a midsole; 21. a high-elastic PU gasket; 3. a outsole; 31. a shock absorber; 32. a damping cavity; 33. cutting the streak by a knife; 34. slip-resistant stripes.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

The technical solution in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in figure 1 and figure 2, the damping sole capable of being bent easily comprises a small sole 1, a middle sole 2 and a big sole 3, wherein the small sole 1 and the middle sole 2 are formed by EVA foaming, the big sole 3 is formed by rubber through one-step forming, a bulge is arranged at the half sole part of the small sole 1, the effect of massaging the sole of a foot is achieved, and meanwhile a certain anti-skidding effect is achieved in the shoe.

A shock absorption cavity 32 and a shock absorption body 31 matched with the shock absorption cavity are arranged at the heel of the outsole, and the shock absorption body is preferably high-elastic PU; the bottom of the half sole face of the outsole 3 is provided with a transverse cutting streak which can be cut along the transverse grain of the sole pattern.

Generally, to avoid the cutting mark being too deep and affecting the service life of the shoe, the cutting depth is not greater than 1/2 of the thickness of the sole.

The half sole department of insole 2 is provided with high-elastic PU gasket to increase the holistic shock attenuation effect of sole.

In order to further improve the grip of the shoe, a slip-resistant strip 34 is arranged at the heel of the outsole 3. The anti-slip stripes 34 are made of glass fiber, and are placed at the bottommost part of the mould in the foaming process, and the outsole foaming material is placed on the glass fiber and is foamed together. The friction force provided by the anti-slip stripes enables the finished shoes to be more suitable for indoor places paved with smooth floor tiles or the ground freezing condition in winter in the north.

The above-mentioned curved shock-absorbing sole is implemented by using traditional leather shoes and conventional shoes, but is not limited thereto, and can be matched with vamps of various structures or materials, and the vamps can have any shape, design, size or color so as to form complete footwear products. Such as light sports shoes, casual shoes, and the like. The footwear products adopting the flexible shock-absorbing sole provided by the utility model fall into the protection scope of the utility model.
