The tightening force transmitter has stretchability in foot girth directions set higher than that of the arch support part.

Abstract: A shoe includes a sole, an upper joined to the sole, and a shoe tongue provided in an internal space formed by the sole and the upper. The shoe tongue is formed of a knitted member and includes a ridge portion of inverted V shape along the front and rear directions of the shoe. The shoe tongue is formed of a single knitted member of which side ends on a medial side and a lateral side are each joined to a vicinity of a tangent between a bottom part and a side part in the internal space. In the shoe tongue, part of an area from the ridge portion to the side end on the medial side or the lateral side is formed to have higher stretchability than at least part of other adjacent areas.

Abstract: There is provided a sole having a forefoot support portion supporting a forefoot of a foot of a wearer, a midfoot support portion supporting a midfoot of the foot, and a rearfoot support portion supporting a rearfoot of the foot, the forefoot support portion, the midfoot support portion, and the rearfoot support portion being connected in this order from a front side, the sole including a midsole having cushioning property, in which the midsole includes a cushioning portion formed of a first foam material, and a torsion control portion formed of a second form material having higher hardness than the first foam material, and the torsion control portion includes a first portion extending in a front-rear direction over at least the entire midfoot support portion on a medial foot side, and a second portion extending obliquely rearward from the first portion toward a lateral foot side.

Abstract: A sole includes a midsole body and a buffer member made of a material having hardness lower than that of a material constituting the midsole body. A mounting portion that mounts the buffer member is formed on a surface of a rearfoot region of the midsole body. The buffer member is mounted on the mounting portion in a non-adhesive state. One of the mounting portion and the buffer member includes a reference surface and a protrusion. The other of the mounting portion and the buffer member includes a recess. The recess includes a surrounding wall having a shape that entirely surrounds a periphery of the protrusion.

Abstract: A sole constituting a part of footwear includes a shock-absorbing part provided at least in a rearfoot region, the shock-absorbing part cushioning an impact applied to a heel of a foot upon landing, and a support part provided at least in a midfoot region, the support part being higher in rigidity than the shock-absorbing part and supporting a midfoot portion of the foot, the support part includes a support surface, the support surface being provided forward of the shock-absorbing part and having a shape extending from one end to the other end in a width direction, and the shock-absorbing part includes a recessed surface located at a height position lower than the support surface, and a plurality of columnar bodies each having a shape extending from the recessed surface to a height position identical in height to the support surface.

Abstract: An upper includes an upper main body that covers an instep of a foot. A first region and a second region adjacent to the first region are formed in the upper main body . The upper main body includes: a first linear body provided across the first region and the second region or provided only in the second region; and a second linear body provided in the first region while avoiding the second region and having an end located at a boundary portion between the first region and the second region. The first linear body and the second linear body have mutually different stretchability.

Abstract: A shoe is constituted of an upper, a sole, and a shell in which the upper and the sole are inserted. A shoe making assistance apparatus that assists making of a shoe includes an input device that accepts foot form data, a processor that selects at least one type of a shell model from among a plurality of types of shell models different in shape based on the foot form data accepted by the input device, and an output device that provides output of the shell model selected by the processor.

Abstract: A method of manufacturing a shoe includes preparing a flexible shell having an internal space, preparing an upper body in a form of a bag, the upper body being provided with an opening in a portion corresponding to a topline, preparing a sole body, accommodating the upper in the shell, partially fixing the shell and the upper body, and forming the upper body with a last being located in the upper body accommodated in the shell, taking the last out of the formed upper body, and inserting the sole body in the shell.

Abstract: A shoe comprises a flexible shell having an internal space and a sole body accommodated in the shell. The shell includes a bottom wall portion and a peripheral wall portion. The bottom wall portion and a portion of the peripheral wall portion adjacent to the bottom wall portion define a lower space which is a space of the internal space in which the sole body is disposed. A portion of the peripheral wall portion located above the portion adjacent to the bottom wall portion forms an upper space of the internal space that is a space in which the wearer's foot is inserted. The bottom wall portion covers a lower surface of the sole body and thus has an external surface configuring a tread of the shoe.

Abstract: A shoe includes: an upper; a tightening tool disposed above an instep of a wearer and capable of applying, to the upper, tightening force for drawing portions and on the both sides in a foot width direction of the upper; and an arch support part provided such that tightening force applied to a first side portion in a foot width direction of the upper can be transmitted to the arch support part. The tightening force transmitter has stretchability in foot girth directions set higher than that of the arch support part.

Abstract: A plurality of rubber-made medial cleats project from a base surface of an outsole in a medial portion of a forefoot portion, and a plurality of rubber-made lateral cleats project from the base surface of the outsole in a lateral portion of the forefoot portion, wherein a first engaging surface of each of the medial cleats faces toward a posterior direction or an obliquely posterior direction and a second engaging surface of each of the lateral cleats faces toward an anterior direction or an obliquely anterior direction.

Abstract: A flexible member includes a reinforced area reinforced by first and second reinforcement portions, wherein: the area is defined by the posterior edge of a first reinforcement portion and the anterior edge of a second reinforcement portion; the first and second reinforcement portions are smoothly continuous with each other without gaps; the perimeter of the area is completely surrounded by the first and second reinforcement portions; the virtual first center line of the area extends obliquely forward and upward; and the angle formed between the first center line and the tread surface of the sole is about 40° to 55°.
