Definitions

  • the present invention relates to an outsole structure of a football shoe, and more particularly, to an outsole structure that can improve rigidity and strength as well as flexibility of an outsole.
  • an outsole of a shoe receives various pressures as well as bending at the time of a dash, stopping, kicking or feinting.
  • a conventional outsole of a football shoe has an equal rigidity and strength at its every portion.
  • rigidity, strength and flexibility of the outsole that are highly required during games could not be made compatible at the same time.
  • each of studs 100 provided on the sole surface has a nearly equal size to each other and the studs 100 are disposed generally uniformly on the whole sole surface. That is, arrangement of conventional studs on the sole surface is determined in the light of appearance.
  • some or all of the studs generally have truncated cone shapes or solid cylindrical shapes, and these studs 100 have relatively greater bottom areas. Therefore, the studs sometimes are not stabbed into the ground. In such a case, a slippage will occur between the stud and the ground during various movements in a game.
  • EP 0123550 discloses a cleated athletic shoe with a plurality of abutting elements extending downward from an outsole layer to prevent downward flexing of the ball and toe area of the outsole layer below its normal unstressed position, while at the same time permitting further upward flexing in order to alleviate physical ailments known as turf toe in a football player.
  • WO 00/57740 discloses a contoured platform to be used in an article of footwear including a curved arch portion and/or a raised portion, such that the contoured inner and outer surfaces extend beyond the arch of the footwear.
  • FIGS. 4 and 5 each show a sole pressure distribution diagram where a sole pressure actually applied to a pivot foot of a soccer player is indicated.
  • FIG. 4 illustrates a diagram for an instep kick
  • FIG. 5 illustrates a diagram for feinting.
  • a sole viewed from a bottom side of a left foot is shown, and a medial side of the foot is shown by a symbol "M” and a lateral side 5 of the foot is shown by a symbol "L”.
  • M medial side of the foot
  • L a lateral side 5 of the foot
  • a sole pressure becomes higher.
  • an outsole is divided into six portions, i.e. a heel portion A, a tread portion B, a toe portion C, a midfoot portion D, an arch portion E and a toe root portion F (see FIG. 3).
  • a sole pressure is relatively high at a heel portion, tread portion, toe portion and midfoot portion of a foot, whereas a sole pressure is relatively low at an arch portion and toe root portion of the foot.

  • the heel portion, tread portion, toe portion and midfoot portion are made more rigid and thus less bendable because higher sole pressures will be applied to these portions during various actions.
  • the arch portion and toe root portion are made less rigid and thus more bendable because sole pressures applied to these portions are relatively low during various actions and further bendability is required at these portions.
  • the rigidities of the above-mentioned six portions of the first invention may preferably be designed in the order; (heel portion) > (tread portion) > (toe portion) > (midfoot portion) > (arch portion) > (toe root portion).
