Description

{FUNCTIONAL RUNNING SHOES}

The present invention relates to a functional running shoe, and more particularly, to a shoe sole structure that absorbs the impact of a heel primarily by allowing the backing member to contact the ground first when the wearer is walking or running, Which absorbs the impact of the heel, and thirdly, the backing member itself absorbs the shock, thereby relieving the impact of the heel.

There are three main types of landing patterns that users take to the ground when they run their running shoes. Fore-foot running with the front ball first reaching the ground, mid-foot running with the sole touching the ground at the same time, and running with the heel touching the ground first.

Most users here prefer to run with the heel touching the ground first, resulting in a sustained accumulation of impact on the calf when the heel is landed, resulting in Achilles tendinitis, plantar fasciitis, and knee, hip, and back injuries.

As shown in FIG. 1, in the conventional running shoes, although the degree of difference is different, the bottom surface is in a straight style, and when the user wears it, the impact is applied to the leg which is three times the weight of the user. Therefore, there is a limit to mitigate such a shock only by the material of the middle window.

And the front window groove 136 is recessed in the lateral direction on the third inclined surface 132. [ The front window groove 136 may have a shape in which the cross-sectional area decreases toward the inside of the front window member 130, and preferably has a triangular cross section. The front window groove 136 is communicated with the outside through the front window hole 138b.

The front end of the fourth inclined surface 134 is connected to the front end of the second horizontal surface 131 and is inclined upward toward the front end of the second horizontal surface 131. [ The rear end of the fourth inclined face 134 is connected to the front end of the third inclined face 132. [ That is, the front window member 130 may have a triangular cross section. The fourth beveled surface 134 provides a propulsive force when the wearer walks off the ground so that the wearer can advance faster.

By making the thickness of the front window member 130 smaller than the thickness of the back cover member 120 by 2 to 3 mm or more, the wearer can go forward rhythmically.

The functional running shoe 100 according to the present embodiment includes an intermediate member 140 disposed between the back cover member 120 and the front window member 130 to stably connect the back cover member 120 and the front window member 130 .

The back cover member 120, the front window member 130, and the intermediate member 140 may be made of an ethylene vinyl acetate (EVA) material having excellent elasticity. The nature of these materials can alleviate the shock that is transmitted to the heel in the third place.

3 is a view showing a state in which a front window member and a back window member are attached to a conventional running shoe. Referring to Fig. 3, the backsheet member 120 and the forehead member 130 can be used attached to a conventional running shoe.
