  • insoles solves the whole spectrum of problems arising from the footwear use, as a consequence of the fact that the soles of footwear manufactured, offered and massively used today on exclusively hard, uneven and inelastic surfaces, are manufactured practically as flat surfaces, so that the soles of the feet lean against the so formed flat surfaces of the footwear soles, making the problems as manifesting and reflecting unfavourably on feet in many ways.
  • the technical problem is manifesting as a consequence of the fact that the feet, or the feet bones, respectively, bear the entire body weight, when the body is in upright and walking position, and thus the feet are under pressure in the direction of the flat surface of the footwear sole, so that the bones in the region of midfoot form a certain, generally known bridge, the particular parts of which are detached, with the pertaining distance, from the flat surface of the footwear sole, and therefore, assume all the static and dynamic weight, and owing to that, occasionally complete relying on and leaning against the flat surface of the footwear sole occur, the end result of which is that the deformation of the foot bones and the entire foot occur eventually.
  • the footwear sole is manufactured practically as a flat surface constitutes a further problem to be solved by the present invention, as a result of the fact that the flat surface of the footwear sole causes that the movement in the footwear is limited to the movement of one integrated entirety, meaning that freedom and movement possibilities of particular partial foot parts are eliminated, depending on the effects made on the pertaining partial parts, and the foot in the footwear from the outside, and owing to that, automatic and natural activation and strengthening of the indispensable elasticity of foot muscles, ligaments and tendons, and the feet in their entirety are lacking.
  • the insole according to the present invention by which it is achieved that the conditions such as those, when walking, the foot is in direct contact with a soft, natural surface, like forest soil, a meadow or sand beach are ensured, the conditions for which the foot has been originally and evolutionary made, and owing to which the foot bone deformation is eliminated, ensuring at the same time that automatic and natural activation and strengthening of indispensable elasticity of foot muscles, ligaments and tendons, even the feet in their entirety is achieved by walking, the summary result of which is the preservation of feet functionality.
  • a human being falls within the group of creatures having foot soles, the movements of which are performed by two legs ending in feet (1.1), that bear the whole body weight and that have feet soles on their lower sides.
  • the human foot performs the function of support for the whole body with the weight both of the body itself and the additional weight, and that not only when the body is in upright position when standing but also when it is in motion.
  • the human foot is a complex multiple joint mechanism consisting of bones, joints, ligaments, tendons, muscles and soft tissues.
  • This complex mechanism is an anatomic structure by which a human being, a two-legged creature is relying on the surface and owing to which it achieves stability when walking.
  • the foot must permanently adjust to the change of the mass centre and body centre of gravity and on the other hand adjust to all the kinds and configurations of the surface on which the movements occur, and only in such a way it may perform its functional integrity.
  • the foot is our single connection with the surface, since through it we constantly receive information about the surface on which we walk, inform us on whether the surface is hot or cold, hard or smooth, and based on this we also adjust our body position in the space. This function is possible due to a rich enervation, and the nerve endings of feet are of the same type as the ones found on the face, making the foot an exclusively sensitive organ containing approximately 250.000 glands.
  • the foot structure is a very complex and sensitive formation, which is extremely influential on the human health. Any change of a particular foot element causes a change of other elements and parameters of the whole body.
  • human feet are relatively small. They consist of muscles and bones, whereas the bones of human feet incorporate 25 percents of all the human bones.
  • the foot itself consists of 28 individual bones in total, out of which 26 bones are movable, and connected with joints with 32 joints, elastically interconnected by blood vessels, tendons and very strong ligaments, the number of which is more than 100. 20 muscles of the foot itself and 1 1 muscles of the shank as well as approximately 250.000 sweat glands are annexed (linked) to the various foot segments.
  • Foot bones constitute three clusters: root of foot, forefoot and midfoot
  • Root of foot looking from the front side to the back side, consists of three cuneiform bones (3.3.1) and one cuboid bone (3.3.2), navicular bone (3.3.3), heel bones (3.3.4 and 3.3.5), as well of talus (3.3.6), all the bones being elastically interconnected by ligaments and joints.

  • the foot has three weight bearing points and three bridges, which, due to being burdened by the body weight adhere to each other in such a way to absorb shocks caused by walking. This is called foot elasticity on three characteristic weight bearing points.
  • Foot bones, as well as phalanges/bones M1 , M2, M3, M4 and M5 (6.2) in segments S1 , S2, S3, S4 and S5, (6.2) are elastically interconnected by muscles, blood vessels, tendons and very strong ligaments (6.3), and of crucial importance is that the possibility that the foot bones in the footwear together with those interconnections have the possibility of movement in all the directions, as are necessary according to the anatomic foot constitution.
  • each step represents a complete and unique walk cycle, which starts with the heel strike against a surface, continues with the leaning on the heel, then on the outer edge of the foot, then on the front side of the foot and ends in the big toe resistance, after which a new step begins.
  • the biggest weight during walk is borne by our feet, and consequently by our joints.
  • Human foot is formed to walk on the natural soil and has natural elasticity placed on three weight bearing points. The walking on the soft natural surface, such as grass, sand, and soft soil does not only suit feet, maintaining their flexibility, but evolutionally, feet have been developed exactly for such surfaces.
  • the foot is a complex structure containing 26 movable bones and 32 joints elastically interconnected by blood vessels, tendons and very strong ligaments, created for walking on the natural soil, indicating that it is necessary that the possibility of free movement of each and every bone, as well as every bone cluster, which forms part of the total number of feet bones exists in the everyday locomotion.
  • the surface of the foot sole is of complex form with marked differences between its particular points in the direction vertical to the surface of the foot sole or the cross section, respectively, and that, both in the longitudinal (7.1) and transversal (7.2) directions.
