  • Patent number: 11058170
    Abstract: There is provided a footwear capable of efficiently removing vibrations of specific frequencies that could propagate to the human body upon landing during running or walking. A footwear includes a sole; an upper connected to an upper-side perimeter region of the sole; and a vibration absorbing unit which absorbs vibration generated by an impact upon landing. The vibration absorbing unit includes a platy flexible support portion which has a smaller rigidity in the vertical direction than in the horizontal direction, and a weight portion provided in the support portion. The support portion is fixed to the sole or the upper, surrounding a perimeter of the weight portion.

  • Patent number: 6763615
    Abstract: Disclosed is a shoe sole comprising an outer sole 1F, 1B, a midsole 2 and a reinforcement device 4 made of a resin plate. The reinforcement device 4 is firmly secured to the underside of an arch portion 2M of the midsole 2. At a medial side 11 and a lateral side 10 of the foot, the reinforcement device 4 is shaped like an arch between separated outer sole parts 1F and 1B. A medial foot portion 43 of the reinforcement device 4 is formed to have a higher hardness than a lateral foot portion 40 of the reinforcement device 4. This allows the reinforcement device 4 to have a greater flexural rigidity in its medial foot portion 43 than in its lateral foot portion 40.

  • Patent number: 6685011
    Abstract: This invention is directed to a shock absorbing device for a shoe sole comprising a lower layer 2 having an upper face 21 and an upper layer 3 having a lower face 30. The two layers 2, 3 are both made of an elastomer. The faces 21, 30 are each formed to have substantially a corrugated section. The corrugated faces 21, 30 each have a plurality of top portions 22, 32, bottom portions 23, 33, and inclined portions 24, 34 joining the top portions 22, 32 and bottom portions 23, 33, with the corrugated faces 21, 30 each being formed from essentially a smooth surface. The corrugated faces 21, 30 mate with each other. The two mating faces 21, 30 are spaced apart from each other at the top portions 22, 32 and/or at the bottom portions 23, 33, with gaps 4 being formed at the spaced-apart portions.
