Shoe with cut in the sole
A shoe includes a sole with a midsole, and an upper portion joined to the sole. The midsole includes a cut having a linear shape, and a depth from a first height position to a second height position in a thickness direction. The cut is configured such that a part of the cut has no contact point with an other part of the cut, and the cut forms a V shape at the deepest part on a cross section when opposite inner walls of the cut are spaced from each other.
1 . A shoe, comprising:
a sole comprising an inner sole, a midsole below the inner sole, and an outsole below the midsole, the outsole being configured to be in contact with the ground, the sole having a forefoot region, a midfoot region, and a heel region; and
an upper joined to the sole, wherein
in the midsole, at least one cut of linear shape is provided which has a depth from a first height position to a second height position in a thickness direction,
the cut is provided in the heel region on an upper surface in the midsole,
the cut is configured such that no part of the cut intersects with another part of the cut at the upper surface in the midsole and such that no part of the cut intersects with another cut at the upper surface of the midsole,
the cut forms a V shape at the second height position as viewed at a cross section when opposite inner walls of the cut are spaced away from each other while a load is applied through the upper, and the opposite inner walls are in contact with each other in a normal state when the load is not applied through the upper, and
the inner sole covers the cut.
2 . The shoe according to claim 1 , wherein the cut is provided in an area locally lying in at least one of a lateral region or a medial region of the midsole.
3 . The shoe according to claim 1 , wherein the cut is provided in a region other than a region where the load applied while the shoe is worn is relatively smaller or relatively larger than other regions.
4 . The shoe according to claim 2 , wherein the cut is provided in a region other than a region where the load applied while the shoe is worn is relatively smaller or relatively larger than other regions.
5 . The shoe according to claim 1 , wherein the cut is a plurality of cuts provided at a plurality of discrete positions and having a predetermined linear shape.
6 . The shoe according to claim 1 , wherein the cut is a plurality of cuts provided at a plurality of positions at intervals such that the density differs from the density in another area.
7 . The shoe according to claim 2 , wherein the cut is a plurality of cuts provided at a plurality of positions at intervals such that the density in the area locally lying differs from the density in another area.
8 . The shoe according to claim 1 , wherein the cut is formed such that the depth thereof differs according to a difference in distance to an end of the midsole.
9 . The shoe according to claim 1 , wherein the cut is formed in an oblique direction from a front medial portion to a rear lateral portion or from a front lateral portion to a rear medial portion.
10 . The shoe according to claim 1 , wherein the inner sole covers the cut and contacts the upper surface in the midsole surrounding the cut in the normal state when the load is not applied through the upper.
11 . The shoe according to claim 10 , wherein the cut is provided in an area locally lying in at least one of a lateral region or a medial region of the midsole.
12 . The shoe according to claim 10 , wherein the cut is provided in a region other than a region where the load applied while the shoe is worn is relatively smaller or relatively larger than other regions.
13 . The shoe according to claim 11 , wherein the cut is provided in a region other than a region where the load applied while the shoe is worn is relatively smaller or relatively larger than other regions.
14 . The shoe according to claim 10 , wherein the cut is a plurality of cuts provided at a plurality of discrete positions and having a predetermined linear shape.
15 . The shoe according to claim 11 , wherein the cut is a plurality of cuts provided at a plurality of positions at intervals such that the density in the area locally lying differs from the density in another area.
16 . The shoe according to claim 10 , wherein the cut is formed such that the depth thereof differs according to a difference in distance to an end of the midsole.
17 . The shoe according to claim 10 , wherein the cut is formed in an oblique direction from a front medial portion to a rear lateral portion or from a front lateral portion to a rear medial portion.
