  • Publication number: 20230157407
    Abstract: A sole structure and shoes having the sole structure are provided which enable smooth cutting maneuvers or the like and stabilize a stacking state in the sole structure. An outsole has an elastic structure arranged between a base plate and a lower midsole portion in a thickness direction of a sole structure. The elastic structure includes a plurality of elastically deformable first columnar portions and at least one coupling portion for coupling the first columnar portions adjacent to each other. The elastic structure is configured such that the coupling portion couples second end portions of the first columnar portions adjacent to each other, and that the second end portions are connected, together with the coupling portion, to the lower midsole portion.

  • Publication number: 20210298424
    Abstract: The object is to improve fitting and supporting properties relative to the midfoot region of the foot of the wearer. The upper structure 2 for the shoe 1 includes a stretchable inner upper portion 20 that has a forefoot part F to cover the forefoot region of the foot of the shoe wearer and a midfoot part M to cover the midfoot region of the foot, and an outer upper portion 21 that is less stretchable than the inner upper portion 20 and that is disposed outside the inner upper portion 20 and overlapped with the inner upper portion 20. In the state of a free length that the inner upper portion 20 is extended without slackening via its own weight when the upper structure 2 is inverted upside down, the inner upper portion 20 has a clearance e relative to the outer upper portion 21 at least at the midfoot part M.

  • Publication number: 20210282498
    Abstract: A sole of a shoe has a plurality of lower protrusions and a plurality of upper protrusions arranged at least at a portion of the sole corresponding to a forefoot of a wearer of the shoe. A support includes a planta rest that is arranged in an internal space surrounded by a shoe upper and bridges between a position of the shoe upper corresponding to a medial side of the foot of the wearer of the shoe to a position of the shoe upper corresponding to a lateral side of the foot of the wearer of the shoe in a foot width direction. The planta rest is configured to receive a portion of the planta of the foot of the wearer of the shoe near a base of metatarsal bone and lift the base of metatarsal bone above the sole.

  • Patent number: 10779613
    Abstract: An outsole includes a substantially flat reference surface formed on a lower side of the outsole, and studs projecting downward from the reference surface and each having a projection surface positioned below the reference surface. Midsole hollows are provided in a lower portion of a midsole. The midsole hollows are each defined between an upper portion of the outsole and an associated one of midsole recesses formed in a lower surface of a lower midsole at positions facing upper sides of the studs.

  • Patent number: 10694812
    Abstract: A sole structure is configured such that in a state where a ground surface of an outsole is in contact with the ground surface, when a planta support surface of a deformable part receives a load of a human body, the deformable part is flexurally deformed downward while being supported on a fixed end functioning as a supporting point, thereby allowing the planta support surface to be inclined downward such that a free end of the deformable part moves downward.

  • Publication number: 20190387835
    Abstract: An outsole includes: a first stud projecting downwards in a stationary manner in a vertical direction from a reference surface and having a first projection surface; and a second stud having a second projection surface. The second stud moves in the vertical direction so that, when an external force acts on the second projection surface, the outsole hollow is compressively transformed and the second projection surface comes close to the reference surface.
