The present invention relates to a high-caliber multifunctional footwear insole, which comprises an upper surface and a lower surface having an outer shape corresponding to a sole shape, a side lower end portion having a lower height than a side upper end portion, And a side surface having a side higher than the side lower end of the foot sole, wherein the foot bottom is formed by a height difference between the side lower end and the side upper end along the rim on the upper side of the side lower end, A plurality of fine protrusions are formed on a lower surface of the side lower end portion and a plurality of diamond protrusions are formed at a predetermined interval And a plurality of side projections of triangular shape are formed at left and right sides of the central projection at regular intervals Castle is, the air line of the central protrusion and the side protrusion, the groove shape is formed between the connected together, between the side protrusion is composed of the buffer groove is formed in a line-type. Accordingly, the wearer is provided with excellent elasticity to improve the fit feeling, and the load applied to the heel portion is relieved, so that it is possible to prevent the back and joints from being burdened when walking, thereby relieving fatigue of the legs and body, And the fresh air is continuously supplied to the bottom of the elastic insole due to the repetition of the up and down movement by the load of the heel when the foot is worn after wearing the shoes. Circulation, which reduces the temperature inside the shoe, thereby preventing the generation of odor, thereby preventing diseases such as eczema and athlete's foot and maintaining a healthy foot. It is also known that the foot is pushed or slipped in the traveling direction And the load of the heel is not centered but behind the feet But distributed in the right and left sides are values that are members sense of cushion to maintain a stable connection structure with each other, and is a very useful invention for increasing a chakhwagam yet overcome the phenomenon of the displacement load.
