The present invention is directed to an outsole for use with a shoe and a shoe having an improved outsole. The outsole includes a forward portion and a rearward portion that are connected by a ball-and-socket connection that allows the portions to move freely. The outsole may include a flexible member disposed between two pieces, for example, of the forward portion to allow these pieces to flex freely. The outsole may be used with a sole construction that includes a gel cushion that is adjacent a transparent window member of the outsole.

1. An outsole comprising: a forward portion; and a rearward portion comprised of a heel section and a shank section that are coupled to the forward portion at a pivot point located just behind a transverse arch of a user, wherein the forward and rearward portions are operatively connected to freely allow independent and relative movement of the forward and rearward portions about the pivot point while walking. 2. The outsole of claim 1, further comprising a stiff member in the shank section positioned to cover a substantial portion of the midfoot. 3. The outsole of claim 2, wherein the shank section is shaped to focus the torsional forces exerted upon the heel and shank sections toward the pivot point. 4. The outsole of claim 1, wherein the forward section is comprised of a toe piece and a forefoot piece connected together by a flexible member. 5. The outsole of claim 4, wherein the flexible member is located substantially below metatarsal bones of a user. 6. The outsole of claim 4, wherein the flexible member is located directly below metatarsal heads of a user. 7. The outsole of claim 4, wherein the flexible member is softer than the toe and forefoot pieces. 8. The outsole of claim 4, wherein the toe piece material has a Shore A hardness of greater than about 75. 9. The outsole of claim 4, wherein the forefoot piece material has a Shore A hardness of greater than about 75. 10. The outsole of claim 4, wherein the flexible member material has a Shore A hardness of less than about 85. 11. The outsole of claim 4, wherein the toe piece, the forefoot piece, and the heel section materials have a Shore A hardness of greater than about 85, and the flexible member material has a Shore A hardness of about 70. 12. The outsole of claim 1, wherein the heel section material has a Shore A hardness of greater than about 75. 13. The outsole of claim 1, wherein the forward section is comprised of a toe piece and a forefoot piece connected together by a flexible member and the shank section is comprised of a stiff member positioned to cover a substantial portion of the midfoot. 14. The outsole of claim 13, wherein the shank section is trapezoidal in shape such that it focuses torsional forces exerted on the heel and shank sections toward the pivot point. 15. The outsole of claim 1, wherein the rearward portion comprises a protrusion extending therefrom and the forward portion comprises a flexible connector defining a chamber for receiving the protrusion extending from the rearward portion. 16. The outsole of claim 15, wherein the chamber is spherical and includes an opening and a ridge disposed near the opening for resiliently maintaining the protrusion in the chamber once the protrusion is received therein. 17. The outsole of claim 16 wherein the protrusion has a ball at a free end that is received in the chamber and maintained therein by the ridge. 18. The outsole of claim 17, wherein the connector is transparent. 19. The outsole of claim 15, wherein the protrusion and chamber form a ball-and-socket connection there between. 20. The outsole of claim 19, wherein the ball-and-socket connection is configured to allow relative movement of the forward and rearward portions during walking or swinging of a golf club. 21. A sole construction comprising: an outsole heel section comprised of a bottom surface, a front surface and an arcuate shaped side wall having an upper surface, the bottom surface, front surface and side wall defining a recess, and the outsole further having a transparent, arcuate-shaped window member on the upper surface; a heel cushion configured and dimensioned to fit in the recess; a midsole connected to the outsole; and a gel cushion between the heel cushion and the midsole so that at least a portion of the gel cushion is aligned with the window member.
