Abstract

This invention relates to sporting shoes. In a pair of sporting shoes composed of the upper part and the outsole which is composed of the outer outsole and intermediate outsole with the whole length of the shoe, the intermediate outsole has a slot going across the bottom of a heel and the slot includes the internal space to be able to insert the plug into the slot from both sides of a shoe. And because this plug has enough size to fill the slot, it offers an suitable buffer and glues to the intermediate outsole not to be removable from the outsole in running.

The present invention relates to sneakers. There are a variety of sneakers available for running. Such shoes usually consist of an upper portion and a midsole, ie a sole with a uniform thickness on the inside and outside of the shoe. Although these shoes usually have an outer sole and a middle sole, they are formed to have a constant density along the inside and outside of the shoe and along the length of the shoe.

In human anatomy, when most people run or walk, each foot comes first in contact with the outside of the heel, and then physiologically, the foot touching the ground rotates inward. Thus, the weight of the human being is carried on the outer edge of the foot inward toward the center of the leg. Afterwards, the foot rotates outward and walks toward the big toe to release the foot.

Most racers are known to show different physiological phenomena in each person when running with conventional shoes.

Most people first step on the ground outside the heel of the foot in contact with the earth, and then maintain the state after the foot is turned inward by improper ergonomics.

This improper operation is called transient physiology. In addition, it is known that 3 to 4 times the weight is applied to the lateral edge of the foot when driving, and particularly in the heel portion when driving rather than walking. The concentrated force on the heel has a tendency for most riders to turn their feet strongly inward, as well as a great impact on the heel, and increases wear on the heel of the worn shoe.

SUMMARY OF THE INVENTION An object of the present invention is to provide a pair of sneakers that eliminate the disadvantages inherent in conventional sneakers, and in particular to provide a pair of neutral shoes having a device that reduces abnormal physiological phenomena of the feet when the legs flatten when running. It is a special object of the present invention that the device for reducing physiological activity is that a person wearing sneakers can be varied to suit a particular running pattern.

These objectives consist of a pair of sneakers consisting of an upper sole and a sole of the length of the shoe from the heel to the heel, the sole of which is a pair of sneakers consisting of an outer sole and a middle sole, the middle sole having a special inner-sized heel width. It is obtained by the invention, which is characterized in that it has a slot across it. Plugs are inserted into the slots from both sides of the shoe and these plugs are sized to fill the slots sufficiently to provide adequate stopping and cushioning when driving. In addition, the plugs are designed to be fixed in the midsole so that they do not escape from the midsole while driving due to the force generated every time they walk. These plugs have a different hardness than the material of the midsole and they themselves have different hardnesses.

The sole structure according to the present invention reduces abnormal driving physiology. In addition, the plugs can be exchanged such that the impact is evenly distributed during driving, depending on the wearer's driving pattern, while at the same time a transverse or "neutral" sole is used for the shoe.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

Figure 1 shows the configuration of the plugs required to achieve design conditions where the plugs are simultaneously inserted into the slots from both sides to provide adequate support during use and to be sufficiently secured so as not to escape from the sole during use.

The intermediate sole and the plugs thus joined are usually made of ethyl vinyl acetate (EVA), so that they have sufficient elasticity so that the edges 22 and 24 of the plug 20 can be sufficiently pushed in the insertion space 26, and the plug 30 The rounded ends 28 of are also fitted in a similar space 27 and the plugs 30 are fully inserted to engage the plugs 20, which are constrained together by the internal size of the slots.

Referring to FIG. 2, it is shown that the sole portion consists of an outer sole 36 and an intermediate sole 32, 34.

Outer soles are conventional and have a number of gripping elements or cretes.

The midsole is formed of a composite structure for ease of construction. The slot is formed in the lower half of the middle sole 34 and the upper half portion 32 of the upper portion is bonded to the upper portion to give the inner sole shape and strength when the plug is not inserted, and the upper portion can be adhesively fixed. To provide a surface. The hardness of each element of the midsole 32, 34, 20, 30 changes with the design of the shoe. The hardness of the plugs 20, 30 is changed by the user according to the driving technique or the driving conditions. To do this, it is necessary to supply several plugs of the same size and different hardness to make the present invention effective.

As described above, rotational movement from the outside to the inside of the foot is known to be a physiological action. Most drivers of these physiological phenomena use high density plugs on the inside 20 to minimize excessive physiological phenomena, since high hardness is well tolerated by excessive compression causing excessive physiological phenomena. Similarly, a small number of riders rotating from the inside out use high hardness plugs on the outside.

In addition, the driver is divided into a person whose heel of the foot first contacts the earth and a person who has a flat center contact with the earth. The latter uses a plug having a hardness similar to that of the midsole with less physiological phenomena, while the former uses a plug having a higher hardness as the physiological phenomenon is severe.

It can be seen that the right shoe of the pair corresponds to the left shoe.

Claims (5)

In a pair of sneakers consisting of an outer sole (36) and a midsole (32, 34) that spans the length of the shoe from the top and the heel to the toes, the midsole is a slit that spans the width of the heel portion.
