AI Technical Summary

Benefits of technology

The present invention provides a shoe with a concave portion at the insole where the big toe naturally enters a medially deviated state, reducing the weight load on the big toe and alleviating pain in the foot. A pressing portion at the insole presses adjacent to the heel side of the big toe, causing the first site to sink in the concave portion. The weight load on the other toes is reduced, resulting in a more stable and comfortable shoe. The footwear also lifts the four toes, increasing the clearance between them and reducing discomfort. The straight line connecting the top ends of the four toes is substantially horizontal, providing uniform support and reducing pain from uneven weight load. A projecting portion widens the clearance between the third and fourth toes, further reducing discomfort by sharing the weight load with another pair of toes.

Problems solved by technology

As the symptom of the hallux valgus progresses, sharp pain may be caused by the root portion of the big toe being brought into contact with the insole of the shoe.
This may hinder walking.

Embodiment Construction

[0025]Next, with reference to the accompanying drawings, a description will be given of the preferred embodiment of the present invention. FIG. 1 is a plan view showing a left-foot insole of footwear according to one embodiment of the present invention. FIG. 2 is a cross sectional view taken along A-A in FIG. 1. In FIG. 1, an insole 3 of a shoe 1 being the footwear according to the present embodiment includes a concave portion 31 formed at the region corresponding to the big toe f1 of the foot f, a pressing portion 32 formed so as to be adjacent to the concave portion 31, and a lifting portion 33 formed at the region corresponding to the four toes f2 to f5 except for the big toe f1. Here, the “insole” refers to the element positioned at the bottom plane inside the footwear, and it includes a shoe insert placed on the bottom plane.

[0026]In planar view of FIG. 1, the concave portion 31 is formed at the region corresponding to a first site ranging from the ball f1a of the big toe f1 to...

Abstract

A concave portion (31) for reducing the weight load of the wearer acting on the big toe (f1) is formed at a region in an insole (3) of a shoe (1). The region corresponds to a first site ranging from the ball (f1a) of the big toe (f1) to the tip of the toe. Further, at a region corresponding to a second site adjacent to the heel side of the ball of the big toe (f1a), a pressing portion (32) is formed for pressing the second site, so that the reaction force occurring by the pressing causes the first site to sink in the concave portion (31).

Description

TECHNICAL FIELD[0001]The present invention relates to footwear for alleviating pain in foot caused by hallux valgus.BACKGROUND ART[0002]In recent years, an increasing number of people are suffering from hallux valgus, which is developed by continuous use of shoes not fitting to feet such as high-heeled women's shoes. Hallux valgus refers to the symptom in which the big toe is in the laterally deviated state. That is, the tip of the big toe deflects toward the small toe side, while the root portion of the big toe is bent in a “V”-shape, to project toward the medial side in the foot width direction. As the symptom of the hallux valgus progresses, sharp pain may be caused by the root portion of the big toe being brought into contact with the insole of the shoe. This may hinder walking.[0003]Conventionally, as footwear for alleviating such pain in the foot caused by hallux valgus, what is known is footwear in which a concave portion is formed at the insole at the position corresponding ...
