Abstract

A sole structure for an article of footwear includes an upper layer comprised of a plate member and a lower layer comprised of a plurality of segmented portions separated by flexing regions. The flexing regions may comprise portions of a compressible material. The sole structure accommodates vertical bending and torsion, while limiting lateral bending.

Claims (42)

1. A sole structure for an article of footwear, comprising:

a plate member;

a plurality of segmented portions extending from a surface of the plate member, wherein each of the segmented portions is discrete and detached from each adjacent one of the segmented portions;

a plurality of compressible portions each disposed inside a respective one of the plurality of segmented portions, wherein each of the plurality of compressible portions is discrete;

a central flexing region extending from a forefoot portion of the sole structure to a heel portion of the sole structure, the central flexing region separating the plurality of segmented portions into a first set of segmented portions and a second set of segmented portions;

the plurality of segmented portions being further separated by a plurality of outwardly extending flexing regions, wherein the plurality of outwardly extending flexing regions extend from the central flexing region to side edges of the sole structure;

wherein the plurality of compressible portions is separated by the plurality of outwardly extending flexing regions;

wherein each of the plurality of outwardly extending flexing regions is a void space between adjacent segmented portions and adjacent compressible portions;

wherein the sole structure has a medial side and a lateral side opposite the medial side;

wherein each segmented portion of the first set of segmented portions extends from the lateral side of the sole structure;

wherein each segmented portion of the second set of segmented portions extends from the medial side of the sole structure;

wherein the sole structure has a midfoot portion between the heel portion and the forefoot portion;

wherein the first set of segmented portions extends through forefoot portion, through the midfoot portion, and through the heel portion of the sole structure; and

wherein the plate member includes a plurality of side sections extending from an outer periphery of the plate member, the plurality of side sections defining a sidewall portion, and each of the plurality of side sections is spaced apart from and adjacent to one of the plurality of side sections by a respective gap, and

wherein at least one segmented portion of the plurality of segmented portions includes a bottom portion that is cantilevered.

2. The sole structure according to claim 1 , wherein the gaps are vertically aligned with the plurality of outwardly extending flexing regions at an outer periphery of the sole structure.

3. The sole structure according to claim 2 , wherein the plurality of side sections is vertically aligned with the plurality of segmented portions at the outer periphery of the sole structure.

4. The sole structure according to claim 1 , wherein the central flexing region has a variable width.

5. The sole structure according to claim 1 , wherein the plurality of segmented portions includes a third set of segmented portions, each segmented portion of the third set of segmented portions extends from the medial side of the sole structure, each segmented portion of the third set of segmented portions is disposed at the heel portion of the sole structure, and an intermediate gap separates the second set of the segmented portions from the third set of segmented portions.

6. The sole structure according to claim 1 , wherein the central flexing region has a first width associated with a narrowest portion of the central flexing region and wherein the plurality of outwardly extending flexing regions has a second width associated with an average width of the outwardly extending flexing regions, and wherein the first width is greater than the second width.

7. A sole structure for an article of footwear, comprising:

a plate portion including a first side and a second side;

a plurality of lower segmented portions extending away from the second side of the plate portion, wherein each of the plurality of lower segmented portions is configured to contact a ground surface;

the sole structure including a medial side and a lateral side opposite the medial side;

the plurality of lower segmented portions further comprising a first set of lower segmented portions associated with the lateral side of the sole structure and a second set of lower segmented portions associated with the medial side of the sole structure;

a plurality of compressible portions each disposed inside a respective one of the plurality of lower segmented portions, wherein each of the plurality of compressible portions is discrete;

wherein the first set of lower segmented portions are spaced apart in a longitudinal direction and wherein the second set of lower segmented portions are spaced apart in the longitudinal direction;

wherein the first set of lower segmented portions are separated from the second set of lower segmented portions in a lateral direction by a central flexing region, the central flexing region being a gap;

wherein each lower segmented portion of the first set of lower segmented portions extends from the lateral side of the sole structure;

wherein each lower segmented portion of the second set of lower segmented portions extends from the medial side of the sole structure;

wherein the sole structure has a forefoot portion, a heel portion, and a midfoot portion between the heel portion and the forefoot portion;

wherein the first set of lower segmented portions extends through the forefoot portion, through the midfoot portion, and through the heel portion of the sole structure;

wherein at least one lower segmented portion of the first set of lower segmented portions is entirely disposed in the heel portion of the sole structure;

wherein the plurality of lower segmented portions is separated by a plurality of outwardly extending flexing regions;

wherein the plurality of compressible portions is separated by the plurality of outwardly extending flexing regions;

wherein each of the plurality of outwardly extending flexing regions is a void space between adjacent lower segmented portions and adjacent compressible portions; and

wherein at least one lower segmented portion of the plurality of lower segmented portions includes a bottom portion that is cantilevered.

8. The sole structure according to claim 7 , wherein the at least one lower segmented portion includes a side portion, and the bottom portion is attached to the plate portion by the side portion.

9. The sole structure according to claim 8 , wherein the at least one lower segmented portion of the plurality of lower segmented portions forms a c-shaped channel with the plate portion.

10. The sole structure according to claim 7 , wherein one of the plurality of compressible portions is disposed within a channel formed by the at least one lower segmented portion.

11. The sole structure according to claim 7 , wherein the plurality of lower segmented portions is integrally formed with the plate portion.

12. The sole structure according to claim 7 , wherein the at least one lower segmented portion includes an upper side section, and wherein the upper side section extends outwardly from the first side of the plate portion.
