Description

(a) TECHNICAL FIELD OF THE INVENTION

The present invention generally relates to a foot balance device that adjusts force distribution on human foot and is particularly applicable to leather shoes, sports shoes, loafers, high-heal shoes, and the likes.

(b) DESCRIPTION OF THE PRIOR ART

The economic development and progress makes the opportunity of taking physical activity remarkably reduced in the modern living and the consequence is insufficiency of physiological loading for modern people. This leads to the emergence of disease of civilization, including metabolic syndrome, obesity, hypertension, hyperlipidemia, and deterioration of cardiopulmonary function.
In addition to the diseases of civilization, chronic pains are also very common in the modern society. The general causes for the chronic pains are basically improper motions and gestures that make bones and muscles losing balance. In view of creature evolution, in the evolution course of human beings, humans changed from an animal walking with four legs to an animal walking with two legs. To maintain balance for standing with two legs and walking in an upright posture with the two legs, bones and muscles are forced to coordinate with each other to induce an effect of compensation, so that the human body does not get falling in an upright posture in standing with two legs and also can move forward in the upright, two leg standing posture.
Such a compensation effect is an interaction induced between bones and muscles and such an interaction between bones and muscles may easily lead to improper motions and gestures when humans are standing and walking. Such improper motions and gestures may make bones and muscles losing balance and as a consequence, the chronic pans discussed above, as well as other sours and pains, may occur.
The chronic pains and other sours and pains are generally brought by the general effect of compensation of human body and techniques of the related medical field or science may not be possible to solve these problems. In other words, the current medical or scientific techniques and knowledge cannot provide a simple and effective solution to constantly maintain the bones and muscles of human body in a balanced condition in the every living and is also incapable of avoidance of sours and chronic pains that were mentioned above caused by improper motion and gestures.
When a human body is standing or walking, the perfect condition is that the force that the heel and the sole take is uniformly distributed and the support to the total body weight is substantially at a center of the sole, as shown in FIG. 1, whereby the bone and muscle systems may be kept at a neutral and balanced position when a person is standing or walking. However, under a natural condition, the sole is subjected to influence of the design of shoes. When the heel unduly applies a force, the heal may be hurt and the shoe heal get damaged. On the other hand, when an undue force is applied by the sole, a rush may occur in walking forward, or as shown in FIG. 2, pigeon toeing may occur in walking, where the body weight is not uniformly distributed, making one of heel, sole, or heel and either an inside portion or an outside portion of sole bearing a great pressure. This is adverse to body balance and may change the way of standing or walking to cause improper motion and gesture.
To resolve the above discussed problems, a conventional solution that a podiatrist or a shoe manufacturer may take is to add a post in the shoe, or place an elastic material in a cavity formed in the shoe heel, or adopt a design of heel cup. However, such solutions may sometimes cause an increase of force applied to the heel or sole, making it impossible to resolve the problems. This is because that those know solutions including post, elastic material, and heel cup, although changing the improper gesture caused by non-uniform distribution of force on the heel and sole, cannot be effectively decrease the pressure acting on the heel and sole.
In view of these problems, the present invention aims to overcome the drawbacks of the conventional solution for adjusting pressure acting on foot by providing a foot balance device of which a detailed description of a preferred embodiment will be given as follows.
