Definitions

• the present invention relates to a highly engineered shoe sole developed to fit the natural structure of the human foot and walking.
• the shoe naturally shifts the center of the body inwards from the outside of the shoe area, disperses the weight distribution evenly to the entire area of the shoe soles, thus absorbs and mitigates the impact on the foot that supports the body weight while enabling the triple-time stepping which is most idealistic walking method for our body, and also preventing and correcting deformation of our vertebra that reduces fatigue from walking and enhances physical growth, at the same time that corrects out-toed gaits into a proper walking habit.
• the shoe soles comprise the bottom of the shoes, and depending on types of the shoes, the heels can be separately attached or manufactured without the boundaries.
• the rear portions (shoe heels) of formal shoes are usually separately attached, whereas the shoe heels of athletic shoes or slippers are without partition.
• the back portion of the shoes can be formed as a part of the single body in a shoe sole, or can be separately attached.
• the idealistic way of walking is the triple-time stepping, but the majority of the shoes concentrate the body weight on the heels of the foot, thus delivering the impact to the vertebra that results in pain in the waist, shoulders and the neck, and also deforming the toes and increasing the fatigue from walking.
• part of the rear portions were removed which caused pain when the cut out part strongly irritated and caused pain in the middle of the foot when the shoe is put on for long hours. Also, the cut out parts are slippery when touching the ground which can result in unintended fall.
• the rear portion is formed in a downward curve which thickens the shoe sole too much and results in many problems such as limiting the function of the actual shoe heels, the variety of design and especially blunting the senses of the feet that causes more falls.
• the objective of the invention is to provide an ergonomically fit shoe sole for walking by differentiating the thickness of the shoe bottoms and the rear portion of the shoe sole that touches the ground from the rear part to the front part of the shoes and thus dispenses the center of the body from the outside of the shoe to the inner sole areas that absorbs and mitigates impact on the foot and induces the most proper and idealistic triple-time stepping, correcting the out-toed gaits and preventing the deformation of the vertebra.
• a shoe sole according to an embodiment of the invention is composed by heightening the outer side more than the inner side of the rear portion bottom and lowering the inner side than the outer side of the front portion.

• FIGS. 16 to 19 are rear views illustating the status when walking with the shoes on.
• the back part of the shoe heel 20 or the rear portion 120 touches the ground first, which is different from standing.
• the body weight presses the foot as it touches the ground, the shoe heel
• the rear portion 120 of the shoe touches the ground naturally from the outer side with higher sole thickness to the inner side with lower sole thickness, gathering the feet inwards.
• the shoe induces the steps that places the feet in a paralleled line opposed to out-toed steps when the shoe heal 20 or the rear portion 120 is brought into close contact with the ground.
• the body weight pressure is transferred naturally from the flattened part 21 of the shoe heel 20 or the flattened part 121 of the rear portion
• the center of the body is moved to front of the shoe as it is transferred to the flattened part 11 of the main body 10 or the flattened part 111 of the front portion 110, so the body weight pressure is gradually lessened on the shoe.
• the shoe is twisted more inward as the inner side of the front part of the main body 10 or the front portion 110 which has the smallest sole thickness.
• the shoe By gathering the shoes inward when walking, the shoe provides flexibility and minimizes the pressure of the body weight to the ankle.
• the foot is less fatigued even when walking for a long time, can maximize prevention of slipping, and also prevent and at the same time correct the deformed walking postures so called the out- toed gait.
• the shoe sole provides an idealistic triple-time stepping by aligning the feet, ankle and the shoe in a straight line when walking or standing due to raising the rear portion from the inner side to the outer side, and lowering the front portion of the sole from the outer side to the inner side.
• this invention naturally moves the center of the body from the outside of the shoe to the inside area of the shoe and distributes the weight on the entire shoe area that absorbs and mitigates the impact and reduces fatigue, prevents and corrects deformed walking habits such as out-toed gaits and prevents slipping.
• This invention has a very useful effect of providing an ergonomic shoe sole that is designed to fit the anatomical structure of the foot and walking that constantly and naturally maintains proper walking habits that prevents and corrects deformed vertebra.
