Abstract

A shoe comprises a sole and an upper. The sole comprises a lower sole member and an upper sole member. The lower sole member includes a plurality of sipes and a longitudinal cavity. The longitudinal cavity is at least in a sole midfoot region and extends downwardly from a top surface of the lower sole member. The plurality of sipes extend upwardly from the bottom surface of the lower sole member and intersect the longitudinal cavity such that the plurality of sipes and the longitudinal cavity combine to define a plurality of through openings. The upper sole member is within the cavity and covers the plurality of through openings.

Claims

1. A shoe comprising a sole and an upper operatively secured to the sole, the sole comprising a lower sole member and an upper sole member, the lower sole member including a sole heel region, a sole midfoot region, a sole forefoot region, a medial side, a lateral side, a bottom surface, a top surface, a plurality of sipes, and a longitudinal cavity, the longitudinal cavity being at least in the sole midfoot region and extending downwardly from the top surface of the lower sole member, the longitudinal cavity extending from the sole heel region to the sole forefoot region of the lower sole member, the plurality of sipes extending upwardly from the bottom surface of the lower sole member and intersecting the longitudinal cavity such that the plurality of sipes and the longitudinal cavity combine to define a plurality of through openings, the upper sole member being within the cavity and covering the plurality of through openings;

wherein said plurality of sipes includes at least a first sipe, a second sipe, and a third sipe, the first sipe being in the sole heel region of the lower sole member, the second sipe being in the sole midfoot region of the lower sole member, and the third sipe being in the sole forefoot region of the lower sole member; and

wherein the first sipe extends transversely from the medial side to the lateral side of the lower sole member.

2. A shoe as set forth in claim 1 wherein the second sipe extends transversely from the medial side to the lateral side of the lower sole member.

3. A shoe as set forth in claim 2 wherein the third sipe extends transversely from the medial side to the lateral side of the lower sole member.

4. A shoe comprising a sole and an upper operatively secured to the sole, the sole comprising a lower sole member and an upper sole member, the lower sole member including a sole heel region, a sole midfoot region, a sole forefoot region, a medial side, a lateral side, a bottom surface, a top surface, a plurality of sipes, and a longitudinal cavity, the longitudinal cavity being at least in the sole midfoot region and extending downwardly from the top surface of the lower sole member, the longitudinal cavity extending from the sole heel region to the sole forefoot region of the lower sole member, the plurality of sipes extending upwardly from the bottom surface of the lower sole member and intersecting the longitudinal cavity such that the plurality of sipes and the longitudinal cavity combine to define a plurality of through openings, the upper sole member being within the cavity and covering the plurality of through openings;

wherein at least some of the plurality of sipes extend transversely from the medial side to the lateral side of the lower sole member.

5. A shoe as set forth in claim 4 wherein none of the transversely extending sipes intersect with another of the transversely extending sipes.

6. A shoe as set forth in claim 4 wherein none of the plurality of sipes intersect with another of the plurality of sipes.

7. A shoe comprising a sole and an upper operatively secured to the sole, the sole comprising a lower sole member and an upper sole member, the lower sole member including a sole heel region, a sole midfoot region, a sole forefoot region, a medial side, a lateral side, a bottom surface, a top surface, a plurality of sipes, and a longitudinal cavity, the longitudinal cavity being at least in the sole midfoot region and extending downwardly from the top surface of the lower sole member, the longitudinal cavity extending from the sole heel region to the sole forefoot region of the lower sole member, the plurality of sipes extending upwardly from the bottom surface of the lower sole member and intersecting the longitudinal cavity such that the plurality of sipes and the longitudinal cavity combine to define a plurality of through openings, the upper sole member being within the cavity and covering the plurality of through openings;

wherein the lower sole member is of a first material and the upper sole member is of a second material, the second material being different from the first material;

wherein the first material is of a first durometer hardness and the second material is of a second durometer hardness, the first durometer hardness being greater than the second durometer hardness; and

wherein the longitudinal cavity includes a cavity heel region, a cavity midfoot region, and a cavity forefoot region, the cavity forefoot region being closer to the medial side of the lower sole member than to the lateral side of the lower sole member.

8. A shoe as set forth in claim 7 wherein the cavity heel region is generally midway between the medial and lateral sides of the lower sole member.

9. A shoe comprising a sole and an upper operatively secured to the sole, the sole comprising a lower sole member and an upper sole member, the lower sole member including a sole heel region, a sole midfoot region, a sole forefoot region, a medial side, a lateral side, a bottom surface, a top surface, a plurality of sipes, and a longitudinal cavity, the longitudinal cavity being at least in the sole midfoot region and extending downwardly from the top surface of the lower sole member, the longitudinal cavity extending from the sole heel region to the sole forefoot region of the lower sole member, the plurality of sipes extending upwardly from the bottom surface of the lower sole member and intersecting the longitudinal cavity such that the plurality of sipes and the longitudinal cavity combine to define a plurality of through openings, the upper sole member being within the cavity and covering the plurality of through openings;

wherein the lower sole member further includes a plurality of ground engaging members, each of the ground engaging members being separated from an adjacent one of the ground engaging members by one of the plurality of sipes; and

wherein one of the ground engaging members and another of the ground engaging members that is adjacent said one of the ground engaging members are spaced apart a sufficient longitudinal distance such that the upper sole member is visible via the sipe separating said one of the ground engaging members and said another of the ground engaging members as viewed in a lateral side elevational view of the shoe.

10. A shoe as set forth in claim 9 wherein the sipe separating said one of the ground engaging members and said another of the ground engaging members extends transversely from the medial side to the lateral side of the lower sole member.

11. A shoe comprising a sole and an upper operatively secured to the sole, the sole comprising a lower sole member and an upper sole member, the lower sole member including a sole heel region, a sole midfoot region, a sole forefoot region, a medial side, a lateral side, a bottom surface, a top surface, a plurality of sipes, and a longitudinal cavity, the longitudinal cavity being at least in the sole midfoot region and extending downwardly from the top surface of the lower sole member, the longitudinal cavity extending from the sole heel region to the sole forefoot region of the lower sole member, the plurality of sipes extending upwardly from the bottom surface of the lower sole member and intersecting the longitudinal cavity such that the plurality of sipes and the longitudinal cavity combine to define a plurality of through openings, the upper sole member being within the cavity and covering the plurality of through openings;
