Abstract: When a midfoot portion of a sole is divided by a predetermined sole center line into a medial midfoot region and a lateral midfoot region one on each side in the foot width direction, a rigidity lowering portion, which is provided in the medial midfoot region, is provided and, in such a manner that the bending rigidity of the medial midfoot region around a foot width direction axis becomes smaller than that of the lateral midfoot region, the rigidity lowering portion in the medial midfoot region reduces the bending rigidity of the medial midfoot region due to another factor other than the shape of the medial edge and the shape of the lateral edge of the sole in a planar view.

Abstract: Provided is a last for shaping a shoe upper. The last includes at least an outer peripheral portion composed of a plastic material that is reversibly transformed between a solid state where the plastic material has a certain shape when the shoe upper is shaped, and a plasticized state where the plastic material has fluidity and is thereby deformable.

Abstract: An object of the present invention is to provide a shoe including an upper that is easily conformed to a shape of a last when it is shaped. The shoe includes an upper made of a fiber sheet that includes: a first layer made of knitted fabric or woven fabric that includes yarns having a heat shrinkability and has inner gaps; and a second layer layered on the first layer and made of nonwoven fabric, knitted fabric or woven fabric, and being integrated with the first layer by needle punching.

Abstract: The second transverse groove, provided in an area between the Chopart's joint and the Lisfranc joint, including the navicular bone where the arch of the foot is highest, is deeper than the first transverse groove, and is equal to or deeper than the third transverse groove. Therefore, the rest of the midsole is thin and it becomes easier for the shoe sole to flex, thereby facilitating the upward displacement of the area where the arch is highest. Thus, it is possible to suppress the lowering of the arch even if an exercise is continued over a long time. On the other hand, a flexion area including at least one third transverse groove is provided directly below the talus, and has a larger width than other transverse grooves. This makes it easier for the rear foot portion directly below the talus to flex, thereby facilitating the upward displacement of the area of the arch.
