MIZUNO CORPORATION

Production of customized shoes of a plurality of types each of which has a shape corresponding to a corresponding one of respective feet of a plurality of wearers in different shapes and that can provide similar fit feeling from uppers of same dimensions is enabled. An upper 20 includes a first portion A 1 and a second portion A 2 having a higher stretchability than that of the first portion A 1 . The first portion A 1 is provided at least at an upper body 21 and the second portion A 2 is provided at least at an upper bottom portion 22.

The disclosed systems and methods relate to improved customizable golf club heads. The golf club head can include a first body, a second body, and a fastener. The first body can include a striking face, a first top surface, a first bottom surface, a first heel, a first toe, a first rear wall opposite the striking face, and a hosel. The first body can further define at least one aperture. The second body can be removably attached to the first body. The second body can include a front face, a second top surface, a second bottom surface, a second heel, a second toe, and a second rear surface opposite the front face. The second body can define at least one second aperture. The fastener can extend through the at least one first aperture and into the at least one second aperture to attach the first and second bodies.

Each of midsoles of a plurality of types of soles that constitute a sole series includes an upper midsole and a corresponding one of lower midsoles. Each of the plurality of types of soles is configured such that, in a non-wearing state, while the sole contacts ground at an intersection, a heel region does not contact the ground. While the upper midsoles of the plurality of types of soles are formed to have the same shape, the lower midsoles of the plurality of types of soles are formed to have different shapes such that an angle between a straight line and the ground is a forwardly descending angle that differs between the soles.

The sole structure for a shoe further increases grip performance. The sole structure includes a longitudinally extending sole body. The sole body has a plurality of columnar portions provided at the lower surface of the sole body. The bottom surface of the respective columnar portions has a ground-contact surface. The outer circumferential surface of the respective columnar portions has a plurality of protrusions that protrude laterally.

A boundary portion located between an upper and a midsole in a foot width direction includes a first boundary portion. The first boundary portion is positioned at a portion of the sole corresponding to a lateral side of the wearer's forefoot. An expansion portion is positioned at a portion of the midsole corresponding to the lateral side of the wearer's forefoot. The expansion portion bulges from the first boundary portion toward the lateral side of the sole with respect to the first boundary portion in the foot width direction. An outsole has a roll-up portion protruding upward from a peripheral edge portion of an upper surface of the outsole. The roll-up portion is located at a portion corresponding to the expansion portion of the midsole and covers a peripheral edge portion of the expansion portion from the outside.

A swimsuit includes a fabric for swimsuit. The fabric includes a warp knitted fabric that has elasticity and includes an elastic yarn and a non-elastic yarn. The swimsuit includes, in at least a portion in the fabric thereof, a stripe pattern that is continuous in one direction, and the stripe pattern includes a recessed stripe portion and a protruding stripe portion. At least portion of the stripe pattern includes a warp knitted fabric portion formed by a herringbone structure. The herringbone stripe pattern is formed by the non-elastic yarn and extends along the length direction of the swimsuit. The swimsuit including the fabric has a low surface friction resistance in water.

A resin composition for monofilaments contains a poly(3-hydroxyalkanoate)-based resin component. The resin composition has a melting point peak temperature of 140° C. or higher and a crystal melting enthalpy of 65 J/g or less as calculated from all melting peaks in differential scanning calorimetry. The monofilament containing the resin composition has high strength and elongation. A method for producing the monofilament containing the resin composition contains, in the stated order, (i) discharging the resin composition in a molten state from a spinning nozzle, and then cooling thereby forming a raw yarn and (ii) stretching the raw yarn in at least one direction.

The disclosed systems and methods relate to improved customizable golf club heads. The golf club head can include a first body, a second body, and a fastener. The first body can include a striking face, a first top surface, a first bottom surface, a first heel, a first toe, a first rear wall opposite the striking face, and a hosel. The first body can further define at least one aperture. The second body can be removably attached to the first body. The second body can include a front face, a second top surface, a second bottom surface, a second heel, a second toe, and a second rear surface opposite the front face. The second body can define at least one second aperture. The fastener can extend through the at least one first aperture and into the at least one second aperture to attach the first and second bodies.

A golf club includes: a shaft; an adapter having a shaft insertion portion and a fixation portion; a head having a hosel portion provided with a hosel hole and a through hole; and a retaining member detachably attached to the through hole. The fixation portion is smaller in a second direction than in a first direction, the first direction being orthogonal to the central axis of the shaft insertion portion, the second direction being orthogonal to the first direction. The retaining member is configured to extend from a hosel outer wall through the through hole in the second direction so as to press a cutaway portion.

The disclosed technology includes bat comprising a first hollow barrel, a second hollow barrel disposed in the first hollow barrel and spaced a distance apart from the first hollow barrel, and a compressible material disposed between the first hollow barrel and the second hollow barrel. The disclosed technology further includes a bat, which has a hollow barrel and an internal assembly configured to resist deformation of the hollow barrel. The internal assembly includes a rod disposed longitudinally in the hollow barrel, a ring attached to the rod, a deformable sleeve (a second hollow barrel) disposed around the ring and extending longitudinally in the hollow barrel. The bat can include a compressible material disposed between the hollow barrel and the deformable sleeve.
