Footgear

Abstract

The object of the present invention is to provide footwear that exactly matches the feet of many people, the movement of a big toe inward and away from a second toe is not restricted, movement of the five toes is not limited, the base sections of the toes are stimulated, putting on the footwear is easy, the toes are made uncomfortable, and the footwear will not slip off even during fast walking. The footwear comprises a sole and instep covers formed of a soft material, wherein five openings and holes are provided on toe tip parts of the instep covers, the instep covers serve as guides, the five toes are led to the corresponding openings and holes, the five toes can easily protrude from the openings and holes, and broad sections between the openings and holes serve as straps.

Description

BACKGROUND OF THE INVENTION [0001] 1. Technical Field [0002] The present invention relates to footwear, such as shoes, zori (Japanese sandals), geta (clogs), and slippers, that enables walking in a manner close to walking barefoot by using a constitution such that movement of toes is not restricted, that facilitates the slipping in of toes into the corresponding space between straps (hereinafter called “putting on of footwear” or a variant thereof), that facilitates the heel-to-toe rolling motion, and that naturally works with the foot as a single unit. [0003] 2. Background Art [0004] More than 4 million years are said to have passed since an ancestor of humankind began to walk upright, and 150-180,000 years have passed since the birth of Mitochondrial Eve, considered to be an ancestor of modern humans. For most of this time, man lived barefoot. The sandals of the ancient Egypt, said to be the oldest footwear, first appeared merely four thousand years ago. [0005] The Japanese, after...

Problems solved by technology

Thus there is the problem that people cannot walk normally unless they select the proper shoe size for their feet.

This leads to the problem that, unless a special order is placed for each foot, with foot length, foot perimeter, foot height, arch height, heel width and other measurements taken, people will not find shoes that fit their feet exactly.

As a result the person is forced to use the middle toe, which does not have sufficient strength for the task, or else walks in an unnatural manner, without pushing off, causing injury to knees and back.

In particular, the longer the distance from tip of big toe to shoe tip, the more the push-off function is inhibited.

When movement of the big toe is restricted, the longitudinal arch and the transverse arch are unable to function as cushions, and this brings injury to the knees and back.

In particular, shoes that are pointed in the tip center, which are common among women's shoes, often cause such painful conditions as hallux valgus, bring discomfort to women.

Because walking with shoes on restrains movement of the toes, where capillaries are concentrated and blood can easily accumulate, there is the further problem that the milking action that walking should provide is inhibited.

On the other hand, zori (Japanese sandals), geta (clogs), sandals, slippers and other footwear have the problem of not functioning as a unit with a foot.

Even so, the foot and bottom portion of the footwear separate from each other, causing the problem that when a person walks fast, a ...
