Title: Shock absorption insole

Description:
BACKGROUND OF THE INVENTION  
       [0001] This invention reinforces the function of the shock absorption by three arches which the foot skeleton originally has, gathers the efficiency of a walk, a run, or taking off and landing by that cause, and relates to preventing an obstacle with still more various legs and bodies.  
       [0002] In order that a leg may disregard the shock absorption by the spring action of three arches which it originally has and may ease the shock of a leg, to a sole, gravity is not applied uniformly [the place which has uniform and soft structure] by the conventional insole, but it is concentrated on the grounding point of three arches. However, in the conventional insole, since structure is uniform and soft, three importance sinks and the structure of an arch disappears. This will produce fatigue of a leg, not only an obstacle but athlete&#39;s foot, pustules plantaris, plantar fasciitis, sports anemia, etc, and an obstacle with the whole various bodies will be caused through the backbone.  
       SUMMARY OF THE INVENTION  
       [0003] By dividing qualitatively or structurally the contact part and the non-contacting part with the ground of each arch of a foot and carrying out adhesion fixation of the three discontinuous three arch contact parts on the surface of an insole in a specific position, it protects the function of the shock absorption by the arch. By making discontinuous three arch contact parts it is made not to spoil the shock absorption by the arch, as each contact part can be moved independently, each arch makes possible 3-dimensional the thing for which all from is taken-like, and it aims at preventing fatigue of a leg, and an obstacle or a fall.

     DETAIL DESCRIPTION OF THE INVENTION  
     [0020] Now, this invention is explained in detail. On the base ( 3 ) of the insole made with the somewhat thick sponge which the structure of this invention consists of three layers, and has shock absorption, the skin, etc. A horizontal arch ( 3   a ) inner side longitudinal arch ( 3   b ), an outside longitudinal arch ( 3   c ), on the position of the contact points of these arches, adhesion fixation is gained separate independence and carried out, and three places of an inside [removing a part] point part ( 2   a ) an outside point central part ( 2   b ) which removes a part, and a heel part ( 2   c ) are equipped with the product of the comparatively hard quality of the materials, such as a rubber system or carbon fiber, and a synthetic resin, more highly than a base ( 3 ). Furthermore, those whole upper surfaces are covered with cloth with a comparatively high friction coefficient, or soft leather, and are suck. Thereby—the toe of a tip portion—a part ( 1   a ) and the arch of foot part ( 1   b ) of a central inner side portion can serve as structure low one step, and can carry out strengthening maintenance of the shock absorption by the arch at the time of a walk run further. Since three places of the arch contact part of the insole of this invention have been independent structurally, respectively, a leg can respond to movement of the center of gravity of the body promptly. Consequently, various changes of like 3 dimensional three arches can perform easily raising a like 4 dimensional balance function further, and people being able to respond to inclination of the body promptly and protecting the body from the obstacle of a leg, or a fall. Since it has been independent, the meantime has elastic and soft structure and three arch contact apportions can move the center of gravity to the center point of lower leg bone immediately by the action of an arch even if they can change the distance and height delicately and become unstable posture, they can require a burden neither for muscles nor the Achilles tendon, but can prevent the obstacle of a fall or a leg. By partition each structure portion of the insole of this invention, a flatfoot, hallux valgus, etc. can be corrected or prevented by suiting and preparing the structure of each of that part potion for every individual. By making three arch contact portions high by the component, the middle portion of arch of a leg becomes high, and it has the structure where it becomes easy to secure the space made in the lower part of the arch middle, circulation of air is promoted, and the sports anemia by pressure of the blood vessel of foot bottom athlete&#39;s foot, and a plantaris inflamed membrane can also be prevented.
