Composite sole structure

An article of footwear, comprising:

• a sole structure having a forefoot region, a midfoot region and a heel region, wherein the sole structure includes a plurality of layers comprising:
• a first zone of flexibility located in the forefoot region, wherein a first layer and a second layer are disposed in the first zone of flexibility;
• a second zone of flexibility located in the forefoot region, wherein the first layer, the second layer, and a third layer are disposed in the second zone of flexibility, wherein the second zone of flexibility is more rigid than the first zone of flexibility, and wherein the first zone of flexibility is located closer to a forward edge of the sole structure than the second zone of flexibility is located;
• and
• a third zone of flexibility located in the midfoot region, wherein the first layer, the second layer, the third layer, and a fourth layer are disposed in the third zone of flexibility and the third zone of flexibility is more rigid than the first zone of flexibility and more rigid than the second zone of flexibility.

A sole structure, comprising:

• a bottom plate member having a forefoot region, midfoot region, heel region, a top surface, and a bottom surface, the bottom surface of the bottom plate member forming a ground-engaging surface of the sole structure;
• a cleat member extending from the bottom plate member, the cleat member including a penetrating portion that is configured to penetrate into a ground surface and the cleat member having a depression opposite the penetrating portion;
• and
• an intermediate plate member having a top surface and a bottom surface, the intermediate plate member being more rigid than the bottom plate member and being configured to provide structural support for the sole structure;
• wherein the bottom surface of the intermediate plate member overlies the top surface of the bottom plate member, wherein a portion of the intermediate plate member extends into the depression of the cleat member.

A sole structure comprising:

• an upper plate member having a top surface and a bottom surface, the upper plate member having a first concave indentation in the top surface and a corresponding convex indentation extending from the bottom surface of the upper plate member;
• an intermediate plate member having a top surface, the intermediate plate member having a second concave indentation in the top surface of the intermediate plate member, wherein the second concave indentation in the top surface of the intermediate plate member is configured to receive the convex indentation extending from the bottom surface of the upper plate member;
• and
• a chambered member comprising a plurality of geometrically-shaped columns forming chambers, the chambered member being inserted within the first concave indentation in the top surface of the upper plate member.
