  • Patent number: 12290150
    Abstract: A stud for an outsole includes: an outer tubular portion located on an outsole body and having a tubular shape; and a core portion located inside the outer tubular portion. The outer tubular portion is integral with the outsole body with no seam between the outer tubular portion and the outsole body. An inner wall surface of the outer tubular portion surrounds, and is in contact with, a side surface of the core portion. This configuration reduces separation of the stud from the outsole and firmly holds the stud on the outsole.

  • Patent number: 12262779
    Abstract: A sole reference posture is determined such that a straight reference line connects a toe-tip position and a rearmost end position of a sole top surface, a path length measured along the sole top surface from the origin of the rearmost end position to the toe-tip position is L, an intersection point of a sole bottom surface and a line crossing a position of 0.45×L and orthogonal to the reference line is position C, and the sole is in contact with the ground at position C. In the reference posture, the sole bottom surface is separated from the ground at a heel portion and a toe portion, and an inequality ??5 is satisfied, wherein ? is an angle between a straight line connecting a heel central position of 0.15×L with a metatarsophalangeal joints position of 0.68×L and the ground.

  • Patent number: 12096817
    Abstract: To achieve a favorable feeling particularly during running. A midsole includes: a first midsole portion; and a second midsole portion stacked on the first midsole portion in a thickness direction of the midsole and made of a material having a lower hardness than a material forming the first midsole portion. In a cutting plane when the midsole is cut along a foot width direction at a location corresponding to the sustentaculum tali of a foot of a wearer, the first midsole portion and the second midsole portion have a relatively-low hardness at a location corresponding to the calcaneus of the wearer, and a relatively-high hardness in an area ranging from a location corresponding to the sustentaculum tali to a medial instep side.
