Abstract

A support is configured such that a bulge is allowed to deform toward a deformation space due to the deformation space when the deformation space is in an open state, and that the bulge is allowed to deform upward and a buffer member is compressively deformed when the deformation space is in a closed state.

First claim

What is claimed is:

1. A sole structure for a shoe, the sole structure comprising a sole body, wherein
a support is provided to a heel area of the sole body, the heel area supporting a heel of a wearer of the shoe,
the support includes:
an upper plate configured to support a foot of the wearer;
a lower plate provided below the upper plate; and
a buffer member which is elastically deformable, provided between the upper plate and the lower plate, and has a lower Young's modulus than the upper plate and the lower plate,

the lower plate includes a plurality of bulges, each of which is elastically deformable, and a bottom of each of which protrudes downward, the plurality of bulges forming a corrugated shape including upwardly curved portions and downwardly curved portions alternately arranged in a longitudinal direction of the shoe,
the buffer member is disposed to extend along an outer peripheral edge of the heel area, the outer peripheral edge of the heel area corresponding at least to both of a medial side and a lateral side of the wearer of the shoe, the buffer member covering, from above, the plurality of bulges entirely in the longitudinal direction of the shoe,
the buffer member includes a plurality of deformation spaces provided above each of the plurality of bulges and extending through the buffer member in a direction perpendicular to a thickness direction of the sole body, each of the plurality of deformation spaces being a hollow or in a shape of a recess, and
the support is configured such that the plurality of bulges are allowed to elastically deform toward the plurality of deformation spaces due to the plurality of deformation spaces when the plurality of deformation spaces are in an open state, and that when the plurality of deformation spaces are in a closed state, the plurality of bulges are allowed to elastically deform upward and the buffer member provided above the plurality of bulges is compressively deformed while being sandwiched between the upper plate and each of the plurality of bulges.

2. The sole structure of claim 1 , wherein
the upper plate includes a lifting portion formed at each of both ends of the upper plate in the foot width direction, and extending upward.

3. A shoe comprising the sole structure of claim 1 .

4. A shoe comprising the sole structure of claim 2 .
