Definitions

  • the present invention relates to a shoe that has a structure that is comfortable to wear and that can efficiently convert an impact at landing to a propulsive force when kicking, and is suitable for running and walking.
  • conventional running shoes and walking shoes (hereinafter simply referred to as shoes) disperse and reduce the impact on the soles at the time of landing, and obtain flexibility and propulsive force when kicking.
  • the cushion material 24 is disposed over the entire 20 soles 22.
  • a shoe having such a configuration for example, a configuration disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2002-85104) is known.
  • Patent Document 2 Japanese Patent Laid-Open No. 2010-162318.
  • the hard tread plate 31 and the hard ground plate 32 are joined to each other by a joint 34 of the heel part (rear foot part) with an appropriate gap 33 so that the gap 33 is obtained.
  • a leaf spring 35 having a restoring force to return to the original gap 33 is formed, and this leaf spring 35 is attached to the bottom of the shoe with a forefoot portion of a rigid stepping plate 31. It is a shoe of composition.

  • an object of the present invention is to provide a shoe that is lightweight, can improve the cushioning properties and the propulsive force obtained at the time of kicking without impairing the comfort, and can be easily mass-produced with a simple configuration.
  • the present invention covers a shoe body portion into which a foot is inserted and a required range in the length direction of the bottom surface side of the shoe body portion, and is fixed to the bottom surface side of the shoe body portion only at a required position in the front foot portion. And a cushion material attached to at least both end positions in the length direction of the hard plate on the ground contact surface side.
  • the required range is preferably the entire length direction of the shoe main body. Thereby, the choice of the attachment position of a cushion material can be increased.
  • the required range is a range from the forefoot part to the buttocks part excluding the toe part. Accordingly, it is possible to improve the flexibility of the shoe main body when kicking and the followability of the hard plate to the shoe main body.
  • the cushion material is attached to the position of the toe portion on the bottom surface side of the shoe main body portion. Therefore, it is possible to improve the comfort when kicking and increase the repulsive force.
  • the hard plate is formed in a curved shape protruding toward the ground surface side at the position of the forefoot part. This makes it easier for the hard plate to follow the shoe body when kicking, and the distance to disengage from the heel of the shoe body (the distance that separates) is shortened, so the moment of inertia of the shoe is reduced, and during running It can reduce foot fatigue and burden.
  • the cross-sectional shape in the width direction of the hard plate is preferably formed in a corrugated shape.
  • the hard plate is formed so that the bending resistance in the range of the forefoot portion is smaller than the bending resistance in the range of the middle foot portion to the heel portion. As a result, the flexibility of the shoe during traveling can be ensured, and the repulsive force obtained during kicking can be increased.
  • the hard plate and the cushion material protrude to the rear side of the shoe main body. This promotes the dispersion and mitigation of impact during landing.
  • the cushion material can be disposed on the grounding surface side of the hard plate is widened, options for the attachment position of the cushion material can be increased, and the cushion material can be disposed according to the user's preference.
  • the cushioning material can be locally disposed on the ground contact surface of the hard plate without impairing the comfort. Since the hard plate is fixed to the bottom side of the shoe body only at the required position on the forefoot, the shoe body is separated from the heel (rear foot) of the shoe body when the kick plate is kicked off. The bendability can be maintained. By disposing cushioning materials at both ends (toe or forefoot and heel) in the length direction of the ground plane side of the hard plate, there is no need to place cushioning material on the middle foot, Weight reduction is possible.
  • the cushion material by locally disposing the cushion material on the ground contact surface of the shoe, the amount of deformation of the cushion material increases, and the cushioning properties and repulsive force are improved. That is, the impact when landing during running is absorbed by the cushion material of the buttocks and forefoot, and the cushion material of the buttocks is restored along with the weight shift, so that the user wearing the shoes is pushed up and the forefoot part The cushion material will be further compressed. Therefore, the hard plate and the shoe main body are inclined forward, and the return of the shoe can be promoted. Furthermore, when the kicking is started, the compressed cushion material of the forefoot part is restored, so that the body of the user wearing the shoes is pushed upwards and the propulsive force is generated. As described above, it is possible to efficiently convert the energy stored by deforming the cushion material at the time of landing to the propulsive force at the time of kicking. Furthermore, since the configuration can be simplified, shoes that are lightweight and suitable for mass production can be provided.
  • the shoe 10 in the present embodiment includes a shoe main body 1 into which the foot F is inserted, a hard plate 2 having a size that covers a required range in the length direction of the bottom surface of the shoe main body 1, A cushion material 3 attached to the grounding surface side of the hard plate 2 is provided.
