Definitions

  • the invention relates to a shoe with a sole, which has a convex shape, wherein the sole has a midsole and an outsole.
  • Instabil quaternary depression which consists partly of a soft material. This is to simulate running as on sand or barefoot and lead to a more conscious and targeted movement.
  • Such a shoe is for example from the EP 0 999 764 B1 known.
  • the shoe has a sole body made of a soft material in the heel area, which causes the foot to be damped during placement. This is intended to reduce the impact load on the joints and the spine.
  • the sole has a pivot axis which is designed to be flexible in order to facilitate unrolling.
  • EP 1 785 048 A1 Another shoe with a convex sole is made of EP 1 785 048 A1 known. This has in addition to a soft sole body in the heel area a kink area in the front half of the sole. The sole construction should allow both a smooth appearance and a smooth unrolling.
  • Object of the present invention is therefore to provide a shoe, in addition to a good cushioning when putting on and while walking the required
  • roller-shaped elements preferably have a different size, wherein preferably the largest element is placed on the heel and the smallest element in the middle of the sole, so that the elements have a descending size from the heel to the middle of the sole.
  • roller-shaped means elongated elements which have a significantly greater longitudinal than transverse extent.
  • the cross-section of the roller-shaped elements is oval in the broadest sense, and due to the fit in the sole or in recesses of the midsole individual sections of the cross section may also be straight, so that an oval cut is formed.
  • the two front roller-shaped elements are arranged approximately so that both elements approximately in the middle of the sole, i. in the center of gravity of the shoe, in which it is in a horizontal position.
  • the middle of the sole is considered in the broadest sense next to the exact center of the sole and the entire middle third of the sole.
  • the three roll-shaped elements closest to the heel are also referred to as the back elements.
  • the two roller-shaped elements closest to the sole center are correspondingly as front elements.
  • the rear elements serve while the damping of the shoe, while the front elements form a resistance to the rolling motion while walking.
  • the two front cylindrical elements in the middle of the sole preferably have the same hardness and consist of the same material. Particularly preferably, they are made of rubber or a thermoplastic material.
  • the front elements are in one embodiment part of the outsole and integrated into it.
  • the midsole has at the corresponding locations recesses for receiving the roller-shaped elements.
  • the three rear roller-shaped elements closest to the heel are preferably made of ethylene vinyl acetate (EVA) or other elastic material that aids cushioning.
  • EVA ethylene vinyl acetate
  • the back elements are preferably integrated as separate form elements in the midsole, i. inserted in this.
  • the outsole of the shoe according to the invention is preferably an abrasion-resistant outsole of thermoplastic or rubber.
  • the material is preferably chosen so that the sole is non-slip.
  • the two roller-shaped elements are integrated in the middle of the sole in the outsole.
  • the midsole preferably consists of a convex molded body with recesses for the roller-shaped elements.
  • the midsole is polyurethane.
  • the material of the midsole is chosen so that, as with all instability shoes, it leads to the destabilization of walking.
  • the material chosen is also shock-absorbent to protect the joints and spine while walking.
  • the three roller-shaped elements in the heel area are preferably made of ethylene vinyl acetate (EVA).
  • EVA ethylene vinyl acetate
  • the three roller-shaped elements in the heel area preferably have increasing degrees of hardness towards the middle of the sole.
  • the elements are preferably inserted in the midsole.
  • the hardness (Shore hardness) can be, for example, from the heel to the shoe center 40 °, 45 °, 50 ° and 55 °.
  • the shoe according to the invention additionally has a shoe upper, which is designed, for example, as a sports shoe, leisure shoe or sandal.
  • the shoe according to the invention optionally has an insole and / or an insole.
  • the shoe according to the invention additionally contains a stabilizer. This stabilizer is e.g. poured into the midsole and e.g. made of a plastic like nylon. The stabilizer preferably has a length of 70 to 90% of the midsole length, more preferably 75 to 85%.
  • the shoe according to the invention actively trains the addressed muscle groups during normal walking or running.
  • the heel area initially experiences a strong damping due to the cylindrical elements in the heel, which have the lowest hardness. This damping decreases gradually in the course of the rolling movement of the foot forward, since the roller-shaped elements from the heel back to the middle of the sole have an increasing hardness.
  • Due to the damping or sinking of the sole the heel sits lower than the foot center, so that the foot must be actively unrolled from the wearer of the shoe to allow it to move forward. Due to the strong cushioning of the heel and the deep sinking an active foot movement forward is necessary.
  • the resistance to the rolling motion increases during the movement.
  • the resistance is generated on the one hand by the decreasing damping in the heel and on the other hand by the roller-shaped elements in the middle region of the sole, over which the wearer must move the foot away.
  • the rolling movement encounters a resistance, which is generated by the solid cylindrical elements integrated in the sole, preferably the outsole.
  • These two front cylindrical elements have a greater hardness than the three rear cylindrical elements.
  • the wearer of the shoe must actively support the rolling forward, ie it must roll over the roller-shaped elements. For this additional muscle power is necessary, which also trains the mentioned muscle groups.
  • a roller-shaped element In the middle of the sole, only a roller-shaped element could be used. According to the invention, however, two front elements are preferably used. This has the advantage that the kinetic energy, which is transferred after overcoming the first front element as momentum forward, is somewhat reduced by the second, smaller element, because here again a resistance is overcome. The kinetic energy that is transmitted to the front, is thereby reduced, so that the wearer of the shoe is not catapulted forward, but "dosed" is pushed in the direction of travel, but then the movement must actively slow down. Due to this effect, the first of the front elements that is positioned closer to the heel is definitely larger than the second front element that is positioned closer to the toe.
  • FIG. 1 shows a shoe 1 according to the invention with a sole 2 and a shoe upper 3.
  • the sole 2 is constructed of a midsole 4 and an outsole 5 arranged thereunder.
  • In recesses of the midsole 4 five roller-shaped elements 6a, 6b, 6c, 7a and 7b are arranged.
  • FIG. 2 shows a side view of the sole 2 of the shoe according to the invention 1. It can be seen that in the midsole 4 five cylindrical elements 6a, 6b, 6c, 7a and 7b are arranged. The cross-section of the cylindrical elements decreases from the heel 8 to the middle of the sole 9 from. While the element 6a is the largest element, the element 7b arranged in the sole center 9 forms the smallest element. The sizes thus decrease in order 6a to 6b to 6c to 7a to 7b.
  • the three roller-shaped elements 6a, 6b and 6c, which are arranged in the region of the heel 8, are preferably made of an elastic material and serve to cushion the shoe 1 when placing the heel 8.
  • the two cylindrical elements 7a and 7b which are in the range the sole center 9 are made of a harder material. These form a resistance against which it is necessary to work during the unrolling of the foot.
  • the two middle roller-shaped elements 7a and 7b are also designed differently sized here, but they can also be made almost the same size.
  • FIG. 3 shows an exploded view of the shoe 1 according to the invention.
  • the sole 2 is arranged under the shoe upper 3.
  • the sole 2 consists of a midsole 4, which has a stabilizer 10, and five different large recesses 11.
  • the recesses 11 serve to receive the roller-shaped elements 6a, 6b, 6c, 7a and 7b.
  • the rear elements 6a, 6b and 6c are separate elements in the present embodiment.
  • the two front elements 7a and 7b are formed as part of the outsole 5.
  • the outsole has a reinforcement in the ball area, which leads to a better stabilization.
