High-heeled shoe sole structure and high-heeled shoe including same

Abstract

The present invention discloses a sole structure of a high-heeled shoe that may have a walking mechanism similar to movement of human walking when a pedestrian wears and walks in high-heeled shoes.A sole structure of a high-heeled shoe of the present invention includes: a front portion supported on the ground; a bending portion that extends from the front portion to be positioned at a rear side of a metatarsophalangeal joint and is bent in an opposite direction to the ground; and a rear portion extending from the bending portion.

Description

TECHNICAL FIELD[0001]The present invention relates to a high-heeled shoe sole structure and a high-heeled shoe including the same that may have a walking mechanism similar to movement of human walking when a pedestrian wears and walks in high-heeled shoes.BACKGROUND ART[0002]During a human gait cycle, at the heel off and toe off period after the midstance, extension of the metatarsophalangeal joints occurs, and simultaneously, inversion and adduction of the heel of the foot occur.[0003]A pedestrian wearing conventional high-heeled shoes suffers from an ankle sprain due to instability of a rearfoot depending on a high heel, when a body's weight is loaded on the ground while standing or walking. Therefore, a sole structure of the conventional high-heeled shoes is made of a very hard material in which a metal shank is inserted from a rear boundary of a front portion that is a portion where the shoe contacts the ground and is supported on the ground to an end of the rearfoot.[0004]In ad...

AI Technical Summary

Benefits of technology

The invention includes a shoe with a bending portion that improves stability when walking in heeled shoes. This bending portion helps to limit flexion of the metatarsophalangeal joint during a swing phase and maintain stability of the foot during a stance phase or standing. Additionally, the shoe has a bending portion at the rear of the metatarsophalangeal joint or a ground support boundary line that moves in the same direction as the metatarsophalangeal joint and the heel during heel off and toe-off while walking. This helps to walk comfortably and stably.

Problems solved by technology

A pedestrian wearing conventional high-heeled shoes suffers from an ankle sprain due to instability of a rearfoot depending on a high heel, when a body's weight is loaded on the ground while standing or walking.

Particularly, when a platform is attached to a sole of the front portion of the high-heeled shoe supported by the ground, movement of the forefoot and rearfoot is not allowed at all.

However, since the conventional high heel sole structure is not flexible, it cannot cope with this, and thus there is a problem in that the heel comes out of the shoe, so that it is difficult to normally walk.

However, even in this case, since it is not bent enough to follow the movement of the foot, and the heel comes out from the shoe as shown in FIG. 27 (c).

Therefore, since the high-heeled shoe to which the conventional sole structure S is applied is not suitable for the movement of the foot according to the walking, it is not possible to effectively support the foot.
