Description

HIGH-HEELED SHOES FOR WOMEN

Technical Field

[1] The present invention relates, in general, to high-heeled shoes for women and, more particularly, to a high-heeled shoe for women which has shock absorption units. Background Art

[2] Generally, footwear is classified into various kinds of footwear depending on the intended purpose. Typically, as footwear having no special purposes, there are shoes suitable for formal dress, sports shoes, sandals, etc. Of these shoes, high-heeled shoes of interest to women are shoes having high heels. Many women use high-heeled shoes regardless of the user's height. Most high-heeled shoes have no separate shock absorption unit, because the heels are reliably fixed to the shoes, unlike typical sports shoes. If separate shock absorption units are mounted to the high-heeled shoes, the thicknesses of midsoles of the shoes must be varied. In this case, because of variation in the shape of the midsoles, the external appearance of the shoes becomes crude. Thereby, the marketability of the shoes will be reduced.

[3] Furthermore, due to structural characteristics of high-heeled shoes, the interiors of the shoes, particularly, heel portions, are made of a hard material having little elasticity, thus increasing the fatigue of users. In addition, in the case of users who wear the high-heeled shoes for a long period of time, specific portions of the user's feet may become deformed. Disclosure of Invention Technical Problem

[4] To date, among various kinds of footwear, women have preferred high-heeled shoes, and many women use high-heeled shoes regardless of a user's height.

[5] However, due to structural characteristics of high-heeled shoes, heel portions of the shoes are made of hard material having little elasticity, thus increasing the fatigue of users. In addition, in the case of users who wear the high-heeled shoes for a long period of time, specific portions of the user's feet may become undesirably deformed.

[6] Therefore, required are high-heeled shoes for women which can markedly mitigate impact transmitted to the soles of a user who wears the shoes, thus reducing the fatigue of the user. Technical Solution

[7] In order to achieve the above purposes, the inventors of the present invention provide a high-heeled shoe for women in which shock absorption units are installed on a lower surface of a front portion of a midsole and in a heel without deteriorating the external design of the shoe, thus absorbing impact when the user walks.

[20] The present invention provides a high-heeled shoe for women having shock absorption units. Mode for the Invention

[21] The present invention provides a high-heeled shoe for women in which shock absorption units are respectively provided under a front portion of a midsole and in a heel. Preferably, the shock absorption unit that is provided under the front portion of the midsole includes one selected from a plurality of protrusions, a spring provided in a depression, and a soft cushioning member. The shock absorption unit that is provided in the heel includes a compression spring which has a T-shaped support along the center axis thereof, or two or more magnets which are placed on top of one another at regular intervals such that the same poles thereof face each other.

[22] Hereinafter, embodiments of the present invention will be described. The embodiments are provided for the sake of facilitating understanding of the present invention, therefore the present invention is not limited to these.

[23] FIG. 1 is a view showing a high-heeled shoe for women, according to a first embodiment of the present invention. As shown in the drawing, the high-heeled shoe 200 includes a midsole 210, an insole 220, an outsole 240, a heel 260 and a top lift 270. A plurality of protrusions 300 are attached to a lower surface of a front portion of the midsole 210. The heel 260 has a hole 260H therein. A compression spring 261 which is oriented downwards is installed in the hole 260H. A T-shaped spring support 262 is provided in the compression spring 261 along the center axis thereof.

[24] The construction of the high-heeled shoe according to the first embodiment of the present invention will be described in detail herein below with reference to FIGS. 2 through 4.

[25] Referring to FIG. 2, the midsole 210 is prepared, which has a convex curved surface from the front end of the high-heeled shoe to the rear end thereof. The midsole 210 is made of polyester or polyurethane. Furthermore, the midsole 210 has a hardness ranging from 40 to 60. The insole 220 is attached to the entire upper surface of the midsole 210. The insole 220 is made of non woven fabric and has a hardness ranging from 25 to 30.

[26] Referring to FIG. 3, the protrusions 300 are integrally attached to the lower surface of the front portion of the midsole 210. The protrusions 300 are integrally provided with the midsole 210 and form a cushion in upward and downward directions. Impact attributable to pressure applied to the shoe is reduced by the cushion formed in the front portion of the sole of the shoe. The outsole 240 is attached to the front portion of the midsole 210 such that the outsole 240 covers the entire lower surface of the front portion of the midsole 210 on which the protrusions 300 are provided. The outsole 240 is made of polyester or polyurethane and has a hardness ranging from 25 to 30.

[27] Referring to FIG. 4, the heel 250 is attached to a lower surface of a rear portion of the midsole 210. The heel 250 has the hole 260H therein and includes the compression spring 261 which is installed in the hole 260H, and the T-shaped spring support 262 which is provided in the compression spring 261 along the center axis thereof. The top lift 270 is attached to the lower surface of the heel 260.

[28] The compression spring 261 which is installed in the heel 260 absorbs direct compressive force transmitted from the sole of the user's foot to the heel 260. Impact attributable to pressure applied to the shoe can be reduced by compression of the compression spring. When the user who wears the high-heeled shoes according to the present invention walks, vertical cushioning operation of the compression spring can mitigate impact applied to the heel of the user, thus reducing the fatigue of the user, and it can effectively reduce impact transmitted from the sole of the user's foot.

[29] FIG. 5 is a view illustrating a high-heeled shoe for women, according to a second embodiment of the present invention. As shown in the drawing, the high-heeled shoe 200 according to the second embodiment includes a midsole 210, an insole 220, an outsole 240, a heel 260 and a top lift 270. A plurality of protrusions 300 are attached to a lower surface of a front portion of the midsole 210. The heel 260 has a hole 260H therein.

[33] Referring to FIG. 8, the heel 260 is attached to a lower surface of a rear portion of the midsole 210. The heel 260 has the hole 260H therein. Two or more magnets 264 are installed in the hole 260H and are placed on top of one another at regular intervals such that the same poles thereof face each other. The top lift 270 is attached to the lower surface of the heel 260.

[34] In detail, the magnet 264 comprises a first magnet 262 and a second magnet 263 which is placed above the first magnet 262 at a position spaced apart from the first magnet 262 by a predetermined distance. The same poles of the first and second magnets 262 and 263 face each other. Preferably, the second magnet 263 comprises at least two magnets which are placed on top of one another at regular intervals.

[35] The two or more magnets which are installed in the hole 260H generate cushioning force in the vertical direction. Furthermore, this cushioning force, along with cushioning force generated in the front portion of the sole of the shoe, mitigates impact attributable to pressure applied to the shoe.
