Description

WO 2010/079509 PCT/IN2009/000691 PERFECT GAIT SHOE Technical Field The present invention relates generally to footwear and more particularly to a shoe that has been adapted to improve a walker's power posture and comfort. This is accomplished by a unique shape & structure of footwear arrangement, which optimizes the use of all muscles of lower limbs and increases the power of the walker, present inventive shoe adopts to the shape of the foot and supports the foot in all stages of normal walking, provides shoe spring or rebound cushioning. Although the shoe provides benefits which extend to all forms of footwear including sports shoes, it has proven especially effective for use by people who walk for exercise and or competition, and is described in the context of race walking below. Background of the invention Locomotion or walking is an important and basic function of humans. Our life depends on walking, Walking is essential in providing the basic necessities of life, 'Movement is life and life is movement' and movement is necessary to all living beings, walking has evolved over millions of years. Human walking is an advanced form of walking of all 1 WO 2010/079509 PCT/IN2009/000691 -living creatures. Each and every muscle, bones are interlinked, developed and evolved to the needs of varied movements of the body, perfected and evolved to the present state, thus human walking is a highly evolved essential organ system, all other organs of our body like heart, liver, kidney, digestive organs are built around the walking organ, "life means walking, walking means life", due to the faulty and unscientific foot wear presently used, normal walking is suppressed, this causes disuse of muscles and humans are suffering from life style diseases, hence foot wear is not just a protective device of the foot but also a health device, foot is the gate way of individual's health. Foot wear has been designed as protective device to the foot, many inventions have been taken place in the field of foot wear yet so far no foot wear has been designed to suit the normal walking style of humans. Human's foot is flat, yet normal walking is not flat it takes many shapes with each step but our present foot wear is flat, sole of the present foot wear is hard and inflexible, foot in natural walking is flexible and changes its shape, hence present foot wear do not promote normal walking due to this rigidity and this defect in the present foot wear leads to life style diseases like obesity, cardiac diseases, osteoporosis arthritis of knee, spondylosis, backache, ankle fractures, hip fractures 2 WO 2010/079509 PCT/IN2009/000691 and other diseases, It is evident that lack of proper walking techniques and exercise are the main reason for the advent of these life style diseases. Normal walking has heel strike, foot flat, heel off and toe off stages. Modern foot wear with its hard rigid soles do not allow so many movements of the foot, this causes disuse atrophy of various muscles of the leg, back and other .parts of the body, in effect our body gradually adjusts to the foot wear, instead of foot wear adjusting to our foot, we are left with one movement of the foot that is foot flat stage, This makes a chain of reactions in the body, the muscles gets disuse, bulk of the muscles decreases, body falls to this trap and succumbs to modern life style diseases as a consequence to the use of badly designed rigid soled foot wear. In recent years to overcome the modern life style diseases there has been an explosion in the physical fitness industry, and correspondingly, in the desire for better equipment which improves an individual's performance of activities which promote good health, perfect walking is an area which requires a particular importance which improve physical condition without unduly taxing an individual's joints, walking have thus popularized and have developed into competition sports such 3 WO 2010/079509 PCT/IN2009/000691 as performance walking or race walking, the sport serves as an increasingly popular form of exercise and recreation, attracting persons of differing levels of skill and physical ability, the fitness industry, however, has been slow in recognizing this trend, and has yet to develop an acceptable walking shoe, walkers have thus been forced to use the running shoes, shoes designed to accommodate a high impact activity which requires very different foot posture, stride technique, impact absorption, and overall shoe use from that of performance walking or race walking. Walking technique consists of series of steps, where each step constitutes a cycle in which the walker shifts from a single support phase to a double support phase and then back to the single support phase. In the single support phase the walker's entire weight is balanced on one foot, the other foot being moved forward so as to move the walker into the double support phase. In the double support phase, the walker's weight is balanced between a leading and a trailing foot, the trailing foot is used to push the walker forward so as to again enter the single support phase, and begin the cycle anew, the aforementioned "push-off' begins during the single support phase when the walker's center of gravity passes over the supporting foot. The walker, at all times, has at 4 WO 2010/079509 PCT/IN2009/000691 least one foot in contact with the ground, reducing the impact associated with each step, and resulting in an overall lower impact exercise routine. With each step in the stride phase, the human's foot lands on the heel or heel strike phase, and moves forward to a planted position or foot flat position with the heel and a ball of the foot supported from below. The ball of the foot acts as a fulcrum, the walker's foot pivoting forward about the fulcrum as the walker's center of gravity passes there over, the foot then moves forward to heel off and toe off stages, This stage accommodates push-off by the walker's toes, the walker's push-off with the trailing foot to assist the leading foot to plant so as to provide the walker with longer stride and stable support. In conventional shoes the sole of the shoes is flat, in some shoe the wearer's heel is elevated relative to the toes and the ball of the foot preventing the movement of the foot and in all the shoes the sole will be rigid, hard and inflexible and flat when the foot is planted, this arrangement of the shoes does not allow double support and causes the disuse of leg, thigh &, hips muscles and decreases in size this leads to improper walking posture, which can lead to injury, bad posture detracts and decreases the wearer's walking power and walking speed, the wearer will tend to stand with a body reclined slightly so as to maintain balance, stand on the front of the foot rather than back of the 5 WO 2010/079509 PCT/IN2009/000691 foot results in an unhealthy posture and increases the likelihood of injury to the walker's lower torso, conventional shoes also detract from walking efficiency because it is necessarily provided a sole with an undersurface which is generally planar, rigid and inflexible from the shoe's heel to the tip of its toe, however, during fast walking, planar shoes may be uncomfortable and does not confirm to the shape of the foot along the various stages of walking, most of the times this deters the foot movement, reduces the use of calf muscle and .hamstring muscle and in turn reduces the bulk of the calf muscles, hamstrings muscles and gluteus muscles. 6 WO 2010/079509 PCT/IN2009/000691 Summary of Invention The problems explained are overcome by the present inventive design. The device according to the invention for perfect Gait shoe 1 hereinafter called Perfect Gait Shoe 1, comprises an upper shoe 2 and a sole 3, the upper shoe 2 is used for the reliable fixing of the walking device 1 to the foot, this can take place by means of straps, such as are used for sandals, laces as are used in the case of beach shoes or an entire upper shoe made from leather or a textile material, what is important is that through said upper shoes 2 the foot is firmly and comfortably connected to the midsole 10. The sole 3 is divided into front section, mid section and rear section, shape of the shoe in unique to the present invention, the front section intersects with mid section at an angulation of 45 to 95 degrees and, the mid section intersects with rear section at an angulation of 85-125 degree. The sole 3 has undersole 12 which has pockets which contains highly compressible materials in the front and rear section, the midsole 10 of the front and the rear sections contains cushion materials, the undersole 12 contains a wedge shaped sole which is made of hard materials in the rear section under sole 12 has hard strip 22 across all sections of the footwear, maintains the shape of the footwear. 7 WO 2010/079509 PCT/IN2009/000691 Statement of invention A Perfect Gait Shoe According to one aspect of the invention, includes the shape of the foot wear, the foot wear is divided into front section, mid section and rear section, the front section of the sole interfaces with the mid section at an angle of 45 to 95 degree, mid section interfaces with the rear section at an angle of 85 to 125 degree. The perfect gait shoe also includes a hard under sole with oval to varied shaped pockets filled with highly compressible material in the front section and the rear section of the foot wear, this provides cushioning of the fore foot and hind foot. The rear section of the foot wear also has a very hard sole in the rear end of the under sole, the newly invented perfect gait shoes of the foot wear helps in shoe confirming to the shape of the foot in heel strike, foot flat, heel off and toe off stages of walking, the inventing design of the sole helps in providing adequate cushion to the foot preventing pain and injury to the bones of the fore foot and hind foot, the hard outer sole helps in transmitting the muscular force to the ground during walking, the invented shoe thus helps in building up of the muscles of hip, thigh, leg and foot by promoting natural walking, this bulk of muscles prevents the onset of modern life style diseases. Present invention is to improve the shoe or the other foot wears of the aforementioned type in such a way that active walking, active 8 WO 2010/079509 PCT/IN2009/000691 standing, active sitting becomes easy and necessary; it is useful in building up of the muscles. As a result daily walking becomes natural promoting the buildup of muscles, strengthening of ligaments, protecting the joints, straighten the posture, all parts of the body gets revitalized and is able to walk faster and longer, this increases the stride and cadence of individuals, helps in competing in various athletic competition, also increases the lung capacity and heart pumping capacity, bulkier leg muscles provides stamina to the body, increases the individual's capacity to work, more work means more burning of calories and less fat accumulation and more productivity, thus the present invented shoes not only prevents the modern life style diseases but also increases productivity. Our new perfect gait walking device is not just a foot wear, it is a new health device which reinvents the perfect walking style, rejuvenates the muscles of the leg and body which in turn rejuvenates all other organs like lungs, heart, and kidney and prevents life style diseases, promotes good health to the mankind. 9 WO 2010/079509 PCT/IN2009/000691 The Walking Shoe in Action The newly invented walking shoe's use is intended for use in pairs, one shoe being placed on each of the wearer's feet, as previously described, walking consists of a series of steps, each step constituting a cycle wherein a walker shifts from a single support phase to a double support phase, and then back to the single support phase, in action during the single support phase, the walker's entire weight is balanced on one foot, the other foot being moved forward so as to move the walker into the double support phase, in the double support phase, the walker's weight is balanced between a leading foot and a trailing foot. The trailing foot is used to push the walker forward so as to again enter the single support phase, and being the cycle anew, Push-off begins during the single support phase when the walker's center of gravity passes over the supporting foot. With each step, an individual's foot lands on the heel and transitions forward from the heel strike position to a planted position with the heel and ball of the foot supported from below by the ground to heel off stage where the fore foot takes 3 times the weight of the body, the unique shape of the foot wear and differing densities of the sole serve. to provide a smooth transition as the walker's weight shifts from the heel to the forefoot, providing smooth movement of the foot from heel to toes 10 WO 2010/079509 PCT/IN2009/000691 and body moves forward. This accordingly helps in full functioning of the muscles of foot, leg, thigh, hip, back and makes each of these muscles strong at least some of the sole compresses the energy and is stored, the unique shape of the sole helps in the maximizing the push of the foot by utilizing the full muscles power of the limb, perfect gait shoe perfectly adopts to shape of the foot and allows maximum shift of centre of gravity of the body without any hindrance, the central support along all sections of the shoe helps to maintain the shape of the foot wear even during the deforming weight that falls on the foot wear during walking.
