Abstract
A shoe sole includes a rear bottom surface part and a toe portion. The rear bottom surface part is formed to extend from a rearfoot portion to a midfoot portion and, when the shoe sole is placed on a flat virtual surface, the rear bottom surface part is in contact with the virtual surface. A height of the toe portion from the virtual surface is set to 170% or greater and 250% or less with respect to a thickness dimension in the rear bottom surface part.
Claims16
A shoe sole comprising:
- a rearfoot portion, a midfoot portion, and a toe portion, and
- a rear bottom surface part formed from the rearfoot portion to the midfoot portion,
- wherein when the shoe sole is placed on a virtual flat surface, (1) the rear bottom surface part is in contact with the virtual flat surface, (2) the toe portion is in non-contact with the virtual flat surface, and (3) a distance from the virtual flat surface to the toe portion is equal to 170% or greater and 250% or less of a thickness of the shoe sole corresponding to the rear bottom surface part.
A shoe sole comprising:
- a rearfoot portion, a midfoot portion, and a toe portion;
- a bottom surface part that includes
- a rear bottom surface part formed from the rearfoot portion to the midfoot portion, wherein when the shoe sole is placed on a virtual flat surface, (1) the rear bottom surface part is in contact with the virtual flat surface and (2) the toe portion is in non-contact with the virtual flat surface, and
- a front bottom surface part that is formed from a front part of the rear bottom surface part and that extends curvedly and upwardly extend to the toe portion so that the front bottom surface part is gradually away from the virtual flat surface;
- an upper surface part that includes
- a first upper surface part formed from the rearfoot portion to the midfoot portion, wherein the first upper surface part includes a surface that is parallel with the virtual flat surface in a unloaded state or a surface that extends downward from a rear part toward a front side with respect to the virtual flat surface in the unloaded state, and
- a second upper surface part that upwardly extends toward the toe portion from a front end of the first upper surface part;
- and
- a deformation restraining part (1) that is formed at least from a portion of the rear bottom surface part and a portion of the front bottom surface part, and (2) that includes a region adapted to face an MP joint part of a foot, wherein
- in the upper surface part, the front end of the first upper surface part is closest to the virtual flat surface, and a front end of the second upper surface part is most distant from the virtual flat surface.
